外文文献译文设计(论文)题目: 电子密码锁的设计专业与班级:学生姓名:指导教师:Introduction of AT89C51Description:The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer with 4K bytes of Flash programmable and erasable read only memory (PEROM). The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set and pinout. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the ATMEL Co.’s AT89C51 is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications.Features:·Compatible with instruction set of MCS-51 products·4K bytes of in-system reprogrammable Flash memory·Endurance: 1000 write/erase cycles·Data retention time: 10 years·Fully static operation: 0 Hz to 24 MHz·Three-level program memory lock·128×8-bit internal RAM·32 programmable I/O lines·Two 16-bit Timer/Counters·Six interrupt source·Programmable serial channel·Low-power idle and Power-down modes·On-chip oscillator and clock circuitry·Full-duplex UART serial port interrupt line·Dual Data Pointer RegisterFunction Characteristic Description:The AT89C51 provides the following standard features: 4K bytes of Flash memory, 128 bytes of RAM, 32 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator and clock circuitry. In addition, the AT89C51 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port andinterrupt system to continue functioning. The Power-down Mode saves the RAM contents but freezes the oscillator disabling all other chip functions until the next hardware reset.The 8051 microcontroller is an industry standard architecture that has broad acceptance, wide-ranging applications and development tools available. There are numerous commercial vendors that supply this controller or have it integrated into some type of system-on-a-chip structure. Both MRC and IAμE chose this device to demonstrate two distinctly different technologies for hardening. The MRC example of this is to use temporal latches that require specific timing to ensure that single event effects are minimized. The IAμE technology uses ultra low power, and layout and architecture HBD design rules to achieve their results. These are fundamentally different than the approach by Aeroflex-United Technologies Microelectronics Center (UTMC), the commercial vendor of a radiation– hardened 8051, that built their 8051 microcontroller using radiation hardened processes. This broad range of technology within one device structure makes the 8051an ideal vehicle for performing this technology evaluationPin Description:·VCC: Supply voltage·GND: Ground·Port 0: Port 0 is an 8-bit open-drain bi-directional I/O port. As an output port, each pin can sink eight TTL inputs. When 1s are written to port 0 pins, the pins can be used as high impedance inputs.Port 0 may also be configured to be the multiplexed low order address/bus during accesses to external program and data memory. In this mode P0 has internal pull ups.Port 0 also receives the code bytes during Flash programming, and outputs the code bytes during program verification. External pull ups are required during program verification.·Port 1: Port 1 is an 8-bit bidirectional I/O port with internal pull ups. The Port 1 output buffers can sink/source four TTL inputs. When 1s are written to Port 1 pins they are pulled high by the internal pull ups and can be used as inputs. As inputs, Port 1 pins that are externally being pulled low will source current (IIL) because of the internal pull ups.Port 1 also receives the low-order address bytes during Flash programming and verification.·Port 2: Port 2 is an 8-bit bi-directional I/O port with internal pull ups. The Port 2 output buffers can sink/source four TTL inputs. When 1s are written to Port 2 pins they are pulled high by the internal pull ups and can be used as inputs. As inputs, Port 2 pins that are externally being pulled low will source current (IIL) because of the internal pull ups.Port 2 emits the high-order address byte during fetches from external program memory and during accesses to external data memory which uses 16-bit addresses (MOVX @ DPTR). In this application, it uses strong internal pull ups when emitting 1s. During accesses to external data memory which uses 8-bit addresses (MOVX @ RI). Port 2 emits the contents of the P2 Special Function Register.Port 2 also receives the high-order address bits and some control signals during Flash programming and verification.·Port 3: Port 3 is an 8-bit bi-directional I/O port with internal pullups.The Port 3 output buffers can sink/source four TTL inputs. When the P3 I write "1" after, they are internal pull-up is high, and used as input. As input, due to the external pull-down for the low, P3 port output current (ILL) This is due to pull-up's sake.Port 3 also serves the functions of various special features of the AT89C51 as listed below:Port 3 also receives some control signals for Flash programming and verification.·RST: Reset input. A high on this pin for two machine cycles while the oscillator is running resets the device.·ALE/PROG: Address Latch Enable output pulse for latching the low byte of the address during accesses to external memory. This pin is also the program pulse input (PROG) during Flash programming. In normal operation ALE is emitted at aconstant rate of 1/6 the oscillator frequency, and may be used for external timing or clocking purposes. Note, however, that one ALE pulse is skipped during each access to external Data Memory.If desired, ALE operation can be disabled by setting bit 0 of SFR location 8EH. With the bit set, ALE is active only during a MOVX or MOVC instruction. Otherwise, the pin is weakly pulled high. Setting the ALE-disable bit has no effect if the microcontroller is in external execution mode.·PSEN：Program Store Enable is the read strobe to external program memory. When the AT89C51 is executing code from external program memory, PSEN is activated twice each machine cycle, except that two PSEN activations are skipped during each access to external data memory.·/ EA /VPP：External Access Enable. EA must be strapped to GND in order to enable the device to fetch code from external program memory locations starting at 0000H up to FFFFH. Note, however, that if lock bit 1 is programmed, EA will be internally latched on reset. EA should be strapped to VCC for internal program executions. When / EA to maintain low, then during this period the external program memory (0000H-FFFFH), regardless of whether an internal program memory.This pin also receives the 12-volt programming enable voltage (VPP) during Flash programming, for parts that require 12-volt VPP.·XTAL1：Input to the inverting oscillator amplifier and input to the internal clock operating circuit.·XTAL2：Output from the inverting oscillator amplifier.·Ready/BUSY: The progress of byte programming can also be monitored by the RDY/BSY output signal. P3.4 is pulled low after ALE goes high during programming to indicate BUSY. P3.4 is pulled high again when programming is done to indicate READY.Oscillator Characteristics：XTAL1 and XTAL2 respectively, reverse amplifier input and output. The reverse amplifier can be configured as on-chip oscillator. Shi Jing oscillation and ceramic oscillation can be used. If using an external clock source drive the device, XTAL2 should not take. More than input to the internal clock signal through a two-way flip-flop, so the external clock signal pulse width without any request, but must ensure that the high-low pulse width requirements.Clock Oscillator：XTAL1 and XTAL2 are the input and output, respectively, of an inverting amplifier which can be configured for use as an on-chip oscillator. Either a quartz crystal or ceramic resonator may be used.To drive the device from an external clock source, XTAL2 should be left unconnected while XTAL1 is driven.There are no requirements on the duty cycle of the external clock signal, since the input to the internal clocking circuitry is through a divide by two flip trigger, but minimum and maximum voltage high and low time specifications must be observed. Idle Mode：In idle mode, the CPU puts itself to sleep while all the on-chip peripherals remain active. The mode is invoked by software. The content of the on-chip RAM and all the special functions registers remain unchanged during this mode. The idle mode can be terminated by any enabled interrupt or by a hardware reset.It should be noted that when idle is terminated by a hardware reset, the device normally resumes program execution, from where it left off, up to two machine cycles before the internal reset algorithm takes control. On-chip hardware inhibits access to internal RAM in this event, but access to the port pins is not inhibited. To eliminate the possibility of an unexpected write to a port pin when Idle is terminated by reset, the instruction following the one that invokes Idle should not be one that writes to a port pin or to external memory.Power-down Mode:In the power-down mode, the oscillator is stopped, and the instruction that invokes power-down is the last instruction executed. The on-chip RAM and special function registers retain their values until the power-down mode is terminated. The only exit from power-down is a hardware reset. Reset redefines the special function registers but does not change the on-chip RAM. The reset should not be activated before VCC is restored to its normal operating level and must be held active long enough to allow the oscillator to restart and stabilize.Program Memory Lock Bits:On the chip are three lock bits which can be left unprogrammed (U) or can be programmed (P) to obtain the additional features listed in the table below.When lock bit 1 is programmed, the logic level at the EA pin is sampled and latched during reset. If the device is powered up without a reset, the latch initializes to a random value, and holds that value until reset is activated. It is necessary that the latched value of EA be in agreement with the current logic level at that pin in order for the device to function properly.Programming the Flash:The AT89C51 is normally shipped with the on-chip Flash memory array in the erased state (that is, contents = FFH) and ready to be programmed. The programming interface accepts either a high-voltage (12-volt) or a low-voltage (VCC) program enable signal. The low-voltage programming mode provides a convenient way to program the AT89C51 inside the user’s system, while the high-voltage programming mode is compatible with conventional third party Flash or EPROM programmers.The AT89C51 is shipped with either the high-voltage or low-voltage programming mode enabled.The AT89C51 code memory array is programmed byte-by-byte in either programming mode. To program any nonblank byte in the on-chip Flash memory, the entire memory must be erased using the chip erase mode.Programming Algorithm:Before programming the AT89C51, the address, data and control signals should be set up according to the Flash programming mode table .To program the AT89C51, take the following steps:1. Input the desired memory location on the address lines.2. Input the appropriate data byte on the data lines.3. Activate the correct combination of control signals.4. Raise EA/VPP to 12V for the high-voltage programming mode.5. Pulse ALE/PROG once to program a byte in the Flash array or the lock bits.The byte-write cycle is self-timed and typically takes no more than 1.5ms.Repeat steps 1 through 5, changing the address and data for the entire array or until the end of the object file is reached.Data Polling:The AT89C51 features Data Polling to indicate the end of a write cycle. During a write cycle, an attempted read of the last byte written will result in the complement of the written datum on PO.7. Once the write cycle has been completed, true data are valid on all outputs, and the next cycle may begin. Data polling may begin any time after a write cycle has been initiated.Program Verify:If lock bits LB1 and LB2 have not been programmed, the programmed code data can be read back via the address and data lines for verification. The lock bits cannot be verified directly. Verification of the lock bits is achieved by observing that their features are enabled.Chip Erase:The whole array and three lock-bit PEROM electrical erase control signals through the right combination and maintain ALE pin is low 10ms to complete. Cleaning operation in the chip, code arrays were all written "1" and in any non-empty memory byte has been programmed to repeat the past, the operation must be executed. In addition, AT89C51 with steady-state logic, and can be in the low to zero frequency under the conditions of static logic, and supports two software selectable power-down mode. In idle mode, CPU stop working. But the RAM, timers, counters, serial port and interrupt system are still working. In the power-down mode, to save the contents of RAM and a freeze oscillator, to prohibit the use of other chip functions until the next until a hardware reset.Reading the Signature Bytes:The signature bytes are read by the same procedure as a normal verification of locations 030H, 031H, and 032H, except that P3.6 and P3.7 must be pulled to a logic low. The values returned are as follows:(030H) = 1EH indicates manufactured by ATMEL(031H) = 51H indicates AT89C51 single-chip(032H) = FFH indicates 12V programming(032H) = 05H indicates 5V programmingProgramming Interface:Every code byte in the Flash array can be written and the entire array can beerased by using the appropriate combination of control signals. The write operation cycle is self timed and once initiated, will automatically time itself to completion. Watchdog (WDT) circuit:Watchdog (WDT) reset circuit is to achieve the main functionality. When the MCU is running an infinite loop occurs when the watchdog (WDT) can play a protection circuit to achieve reduction effect.摘自: http：///p-35268283.htmlAT89C51的介绍描述：AT89C51是一个低电压，高性能CMOS8位单片机带有4K字节的可反复擦写的程序存储器（PENROM）。

The equipment has the advantages of small size, single power supply and a variety of output voltage leads it has a special module. Through the analysis of the hardware structure, we can summarizes each module needs.For example,we often go through the keys to realize the control of the electronic device. Small to watch mobile phone, to the TV computer, to a variety of complex instruments, all need to realize various operations through the buttons. This design is an important part of step for the further research，using buttons to control the display，include some modules like LCD 1602 liquid crystal display，4*4 matrix keyboard，STC89C52single-chip microcomputer and other bine with the Proteus software，the simulation results are displayed on the LCD in 1602 type of data.KEY WORDS: Single-chip; LCD 1602 liquid crystal display; 4*4 Matrix keyboard31 IntroductionWith the development of economy and the progress of science and technology, Microprocessors and peripheral chips have developed rapidly. The newest development of the integrated technology is the CPU chip and external. Like the program memory, data memory, parallel, serial, I/O timing / counter, interrupt controller and other control components are integrated in a chip—single chip. SCM has a manufacturing process CMOS, The smaller lithography process improves integration which make the chip space smaller, lower cost, lower working voltage, lower power consumption. Adopts double CPU structure, increasing the width of data bus, improve the speed and the ability of data processing, a pipeline structure, improve the processing and computing speed, in order to meet the needs of real-time control and processing. To increase the storage capacity, the internal EPROM EPPROM, secure program, to improve the driving capability of parallel port, in order to reduce the peripheral driving chip, increase the logic function and control the external I/O port flexibility. Peripheral in serial mode based expansion; peripheral circuit internal installation is an obvious trend to connect the internet. Reliability and application level is getting higher and higher. Some high-end microcontroller and launched in recent years also contains many special function unit, Such as A/D4converter, modem, communication controller, PLL, DMA, floating point unit etc.So,as we add some external expansion of the circuit and channel interface it can constitute a variety of computer applications, such as industrial control systems, data acquisition system, automatic test system, intelligent instrument, intelligent interface, function module etc. With MCU development and complete structure,SCM has become a powerful tool and will have a higher level and broader development.2 Design of the whole structure of systemThis design is based on single-chip, include matrix keyboard and LCD display module. Single-chip is the first model to select the appropriate target, function, reliability, cost, accuracy and speed control system. According to the actual situation of the topic selection, configuration management model different mainly from the following two aspects: First, supply chain management has strong anti-interference ability; second, SCM has a higher price. For information input module, keyboard selection can use economic benefits and meet the requirements of the 4*4 key matrix keyboard can realize multi function key requirements. As for the output module, using LCD 1602 liquid crystal display module, liquid crystal to achieve key information processing functions after the show.

Liquid crystal display with thin thickness, suitable for large scale integrated circuit directly driven, easy to realize full color display characteristics, has been widely used in many fields of portable computer, digital camera, PDA mobile communication tools etc.1602 liquid crystal is also called the 1602 character LCD, which is a special used to display letters, numbers, symbols of the LCD module. It is composed of a plurality of 5X7 or 5X11 dot matrix character components, each dot matrix character who can display a character, there is a distance between the interval of each, there are intervals between each line, played the character spacing and row spacing, and because of this it is not well display graphics (with custom CGRAM, show the effect is not good). 1602 LCD refers to the display of the content for the 16X2, which can display two lines, 16 characters per line (LCD moduledisplay characters and numbers).63.2 Matrix keyboard module1. Key characteristicsThe keyboard is composed of a number of separate keys, press and release key is through the closed mechanical contact and off to achieve, because of the elastic action of mechanical contact, in the closing and the opening of the moment has a dither. Jitter must be eliminated, include software and hardware elimination.2．Scanning principleFirst determine whether a key is closed, and then one by one scan to further determine which button closure;(1) D0 ~ D3 output 0, level detection line D4 to D7. If the D4 - level D7 all high, said no key was pressed. If the D4 - level D7 is not all high, said the key was pressed.(2) If no key closure, return the scanning. If there is a button closure, in column by column scanning, closed key key number to find out. The D0=0, D1 ~ D3=1, D4 ~ D7 level, if D4=0, said the K1 key is pressed; similarly, if the D5 ~ D7=0, K5 respectively, K9, K13 key is down; if the D4 ~ D7=1, said that without a key is pressed. Then the D1=0, D0, D2, D3 was 1, the scanning of the second columns, which were carried on, until the closure of the key found.4 Software design7The software design mainly consists of keyboard scanning procedures, write instruction code program of LCD module, LCD module display data initialization code written subroutine, liquid crystal display module, liquid crystal display a character subroutine, time delay subroutine and so on. Programming for each module, software programming ended, Keil software was used for debugging, when the various parts of the program debugging is correct, according to the source sequence of calls, the parts together, compile, compile successfully downloaded to the mcu. The result is when the user presses a key, LCD display of the button is pressed after the realization of functional parameters corresponding to the. When the system power supply, P1 port scan cycle and the key button debounce, after completion of input through the SCM processing, output in the P0 port, through the liquid crystal display program content, complete system function.5 ConclusionWith the continuous development of high and new technology, the miniaturization and the miniaturization of electronic products has been achieved.

The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set and pinout. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel A T89C51 is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications. Function characteristicThe A T89C51 provides the following standard features: 4K bytes of Flash, 128 bytes of RAM, 32 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator and clock circuitry. In addition, the A T89C51 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port and interrupt system to continue functioning. The Power-down Mode saves the RAM contents but freezes the oscillator disabling all other chip functions until the next hardware reset. Pin DescriptionVCC：Supply voltage. GND：Ground. Port 0：Port 0 is an 8-bit open-drain bi-directional I/O port. As an output port, each pin can sink eight TTL inputs. When 1s are written to port 0 pins, the pins can be used as highimpedance inputs.Port 0 may also be configured to be the multiplexed loworder address/data bus during accesses to external program and data memory. In this mode P0 has internal pullups.Port 0 also receives the code bytes during Flash programming,and outputs the code bytes during programverification. External pullups are required during programverification.Port 1Port 1 is an 8-bit bi-directional I/O port with internal pullups.The Port 1 output buffers can sink/source four TTL inputs.When 1s are written to Port 1 pins they are pulled high by the internal pullups and can be used as inputs. As inputs,Port 1 pins that are externally being pulled low will source current (IIL) because of the internal pullups.Port 1 also receives the low-order address bytes during Flash programming and verification. Port 2Port 2 is an 8-bit bi-directional I/O port with internal pullups.The Port 2 output buffers can sink/source four TTL inputs.When 1s are written to Port 2 pins they are pulled high by the internal pullups and can be used as inputs. As inputs,Port 2 pins that are externally being pulled low will source current, because of the internal pullups.Port 2 emits the high-order address byte during fetches from external program memory and during accesses to external data memory that use 16-bit addresses. In this application, it uses strong internal pullupswhen emitting 1s. Duringaccesses to external data memory that use 8-bit addresses, Port 2 emits the contents of the P2 Special Function Register.Port 2 also receives the high-order address bits and some control signals during Flash programming and verification. Port 3Port 3 is an 8-bit bi-directional I/O port with internal pullups.The Port 3 output buffers can sink/source four TTL inputs.When 1s are written to Port 3 pins they are pulled high by the internal pullups and can be used as inputs. As inputs,Port 3 pins that are externally being pulled low will source current (IIL) because of the pullups. RSTReset input. A high on this pin for two machine cycles while the oscillator is running resets the device. ALE/PROGAddress Latch Enable output pulse for latching the low byte of the address during accesses to external memory. This pin is also the program pulse input (PROG) during Flash programming.In normal operation ALE is emitted at a constant rate of 1/6 the oscillator frequency, and may be used for external timing or clocking purposes. Note, however, that one ALE pulse is skipped during each access to external Data Memory.If desired, ALE operation can be disabled by setting bit 0 of SFR location 8EH. With the bit set, ALE is active only during a MOVX or MOVC instruction. Otherwise, the pin is weakly pulled high. Setting the ALE-disable bit has no effect if the microcontroller is in external execution mode.PSENProgram Store Enable is the read strobe to external program memory.When the A T89C51 is executing code from external program memory, PSEN is activated twice each machine cycle, except that two PSEN activations are skipped during each access to external data memory. EA/VPPExternal Access Enable. EA must be strapped to GND in order to enable the device to fetch code from external program memory locations starting at 0000H up to FFFFH. Note, however, that if lock bit 1 is programmed, EA will be internally latched on reset.EA should be strapped to VCC for internal program executions.This pin also receives the 12-volt programming enable voltage(VPP) during Flash programming, for parts that require12-volt VPP.XTAL1Input to the inverting oscillator amplifier and input to the internal clock operating circuit. XTAL2Output from the inverting oscillator amplifier.Oscillator CharacteristicsXTAL1 and XTAL2 are the input and output, respectively,of an inverting amplifier which can be configured for use as an on-chip oscillator, as shown in Figure 1.Either a quartz crystal or ceramic resonator may be used. To drive the device from an external clock source, XTAL2 should be left unconnected while XTAL1 is driven as shown in Figure 2.There are no requirements on the duty cycle of the external clock signal, since the input to the internal clocking circuitry is through a语音电子密码锁的设计本设计是采用语音识别技术加键盘控制输入，在凌阳SPCE061A单片机上实现的一种语音电子密码锁的认证系统。

电子遥控防盗密码锁的发展与设计随着人们生活水平的提高和安全意识的加强,各种各样的密码锁广泛进入了人们的生活和工作。
电子式的密码锁市场占有量最大,因为它的成本相对较低,安全性高,操作简单，但是它的安全性不高。
为了解决目前电子密码锁的诸多不安全问题，本文引入遥控技术，红外线遥控技术出现较早，成本低，响应速度快，价格也具有优势。
因为红外线不能穿越砖瓦水泥砌筑的墙体，这在日常使用中经常会造成不便。
居于此本文提出设计无线遥控电子密码锁系统。
系统以AT89S52 单片机为核心，利用无线遥控技术和电子密码锁技术结合，能进一步提高电子密码锁的安全性、可靠性与实用性，降低了硬件成本。
1.绪论1.1 国内外发展状况目前市场上的密码锁主要有以下几类：（1）机械式密码锁。
它具有成本低，抗干扰能力强的优点，同时也具有密码量少，操作频繁，输入密码不易，安全性差，钥匙易于复制的缺点，而且没有自动报警功能，无法拒绝非法用户尝试密码。
（2）固定键盘式电子式的密码锁。
使用固定键盘输入门锁密码。
用户密码位数可以设定，它具有成本较低，密码量大，不易破译的优点和自动报警，错码自锁的功能，但是这些电子密码锁系统都采用的是固定键盘式的，也就是将操作键盘固定在保险箱或门的面板上，这就使得用户在操作时没有隐蔽性，极易被人看见和偷拍而使得密码不安全，因而操作的安全性不高。
（3）红外遥控式电子密码锁。
由于红外遥控技术已经纷纷用于我们的日常生活中，出现了红外遥控技术和密码技术相结合的电子密码锁。
由于红外线和激光都不具备“绕射”能力，用户无法在隐蔽的地方操作，因此也会使用户感到使用不便。
（4）其它密码锁。
市面上还有如手机遥控锁，磁卡式的保险柜锁、智能卡IC 卡式的保险柜锁，指纹保险柜锁等。
磁卡式保险柜锁和智能IC卡式的保险柜锁，虽然都具有更换方便，易于操作的优点，但是由于磁卡本身结构简单、磁条(磁层)暴露在外、存储容量小、无内部安全保密措施，容易被破译，安全性差。
外文文献-电子密码锁的设计
外文资料原文The Design of Electronic Lock PIC 16F628A MicroconrollerToday, we are living in the in the of embedded systems surrounded by devices that based on the embedded systems like cars, washing , medical equipment’s etc.An embedded system is a computer system designed for specific control functions often with realtime computing constraints.It is embedded as part of a complete device which often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal computer(PC), is designed to be flexible to meet a wide range of end-user needs. Embedded systems control many devices in common use today.One of prominent example of an embedded system is a microcontroller , which is a small and tiny computer designated to perform some specific tasks. A microcontroller program(firmware) is the one, which decides what functionality the microcontroller provides to a user. A program that has the ability to run on a microcontroller without the need of an operating system is called as a firmware. That means, a firmware has the privilege to access the hardware directly.This paper tries to explain an electronic lock firmware in detail. The basic idea of microcontroller is to collect all the input and output peripherals in one simple circuit, which represent the microcontroller instead of the large and sophisticated computer with microprocessor and large numbers of peripherals.The firmware directly deals with peripherals and Input/Output ports to give complete functionality of microcontroller.Microprocessor differs from a microcontroller in many aspects. First and the most important aspect is its architecture. In order for a microprocessor to function properly, other components such as memory, peripherals and input output ports must be connected to it. In short, we can say that a microprocessor is the heart of the computer and it works a group with other peripherals/parts of the computer system.On the other hand, a microcontroller is designed to be comprised as a single unit which can perform independently. No other external component is needed for its application because all necessary peripherals and ports are already built into it. Ultimately, it saves the time and space needed to construct devices.With the development of electronic technology, all kinds of electronic products emerge as the times require, electronic lock is one of them. According to the information, electronic lock research from the nineteen thirties began, in some special places early application. The lock is on the after the keyboard to input a password to complete the unlocking process. Study of the lock 's original intention, is to improve the safety of the lock. Due to the electronic lock key size ( code quantity greatly, with machine )Mechanical lock, and can avoid the key being imitated and stay safe hiddentrouble. Electronic lock just remember one password, without carrying metal key, remove people carrying metal.The key of troubles, and by more and more people enjoy. Electronic lock variety, such as fingerprint lock, digital lock, magnetic lock, IC card lock, and other biological. But more practical or key type electronic lock. 2.Nineteen eighties, with the electronic lock special integrated circuits, electronic lock has the advantages of small size, high reliability, high cost, is suitable for use in high security.Occasions, and have power to provide energy, use is limited in a certain range, so it is difficult to popularize, no study has been significant progress.At present, in the western developed countries, electronic lock technology is relatively advanced, full range, electronic lock has been widely used in the intelligent entrance guard system, through a variety of more safety. A more reliable technology to achieve the management of door. In the our country electronic lock overall level still is in on international 70 time around, electronic lock the cost is very high, the market still with buttons.Lock, key type and the card key type electronic lock has been the introduction of the international advanced level, now there are several factory production supply market. But the domestic self-developed electronic lock, the city field structure has not been formed, is applied. The domestic many enterprises also introduced the world's advanced technology, development foreground is very considerable.The system is implemented using assembly language. The purpose of using this language is to get a better picture and understanding of the PIC architecture.Another positive aspect of using assembly language is that it gives very wide and flexible way to interact with microcontrollers even though its implementation is harder than BASIC or C languages, which are used as a language for programming microcontrollers. There are mainly two parts of the system implementations:A. Keypad ImplementationThe system dedicates PORTB for keypad implementation in which 4 pins are reserved for columns and the remaining 4 pins for rows. Hence, the system uses these 8 pins for construction of 16 keys matrix, which makes an efficient use of the limited ports provided in PIC16F628A. There is an important precaution which must be taken while implementing the keypad because, the keypad processing rely on a mechanical process (pressing and releasing keys). This phenomenon generates a spark, which influences the electrical properties of pin while pressing and releasing the key, which causes the pin status to be unstable and can’t be recognized properly whether it is 0 or 1. So, to overcome this, a delay must be provided to give enough time for the pin status to be stable and can be read correctly, this time could be 20ms or more.1. Key ScanningThe keypad design is influenced by electrical phenomena, which states that, if we short circuit two pins, one with zero and the other with high voltage,then both the pin voltage would drop to zero. This fact could be used for designing the keypad.As mentioned above, PORTB is reserved for the keypad and the most significant 4 bits are used for column indexing, which are set as input port (for input port, we must set TRISB register to high ) to check whether they have dropped to 0 voltage when they are attached with the selected row after pressing the key.On the other hand, the least significant 4 bits of PORTB are set to output, and are used for row indexing. Since they are the output ports, they can be set to high (1) or low (0) by the firmware. By setting each row to zero for every key scan, the system can check each column, to see if any one of them is set to 0. If so, this means that one key of that row has been pressed. This process is repeated for all rows to check all the keys. The functions responsible for scanning key are row_scan and col_scan.1.1 Row scanThis function sets every row to zero at a time and calls col_scan function to check if any column pins drop to zero voltage. This function then increments the key variable for each row assignments, to index the row.1.2 Col_scanThis function scans every column pin to check if any one of them is set to zero.B. LCD ImplementationThe other main part of the system implementation is LCD implementation. The LCD configures to operate in 4 bits interface mode, because of PIC16F628A ports limitations.Sending the command 0x20 then 0x28 will configure the LCD to work in 4 bits interface mode , which means that the maximum characters can be displayed are 40 characters for a 20x2 LCD used by the system.Electronic lock technology development so far, has been widely used in higher property security areas as information technology and computer technology and the constant development, electronic lock technology will have greater development. Both at home and abroad, the application of electronic combination lock are common, has the very good development prospect. Electronic combination lock commonly used in daily life and work, it is mainly used for guard against theft. For example,our most common automatic deposit machine, the above is the keyboard type combination lock, if security is not good, bank will not use nature, visible keyboard type combination lock can be trusted. Now, with the progress of science and technology with the development of the electronic combination lock also reached a relatively high level, both on the function, safety performance, and stability is one of the more comprehensive. Now also appeared on the market for fingerprint recognition, is also useful to the human eye and human voice recognition and other high-tech electronic combination lock products. And in order to better achieve confidentiality, people begin to try to use a combination of ways, the password ways are usedtogether, if use fingerprint plus key presses, and voice recognition, etc., so that you can have more privacy. It can be used for bank vault, because for such a performance requirements to the critical point of safety, the use of this combination lock that has a variety of key combination is appropriate, of course we can be bold to try. Even if the combination lock to use some inconvenient, it meet the requirements of the specific bank vault, that is to have extremely high confidentiality, it is special combination lock set for special occasions. So, use your imagination, we can develop more and better electronic combination lock, to meet the needs of public and specific people, to the point of the design of the electronic combination lock reached perfection.So, is extremely broad prospects for the development of the electronic combination lock, and trend of development is the trend of The Times.外文资料译文基于PIC 16F628A单片机电子锁的设计当今，我们生活在嵌入式系统设备的周围，这些基于嵌入式系统的设备如汽车、洗衣机、医疗设备等。

Introduction of SCMSCM is a semiconductor wafer integration: the central processing unit (CPU), memory (RAM and ROM), parallel I/O, serial I/O, timer/counters, interrupt system, the system clock circuit and the system bus microcomputer. With miniature computer properties, thus called the single chip computer, abbreviation microcontroller.Mainly used in measurement and control field. When using single chip, are usually of the measure and control system in the core status and Embedded them so often called on international chip Embedded controller (EMCU MicroController, Embedded security unit.and), or micro controller (MCU, MicroController unit.and). Our country used to use "one-chip computer" this name.MCU is computer technology an important milestone in the history of computer, marks formal formation of the general computer systems and embedded computer system two branches. SCM small volume, low cost, embedded in industrial control unit, robot, intelligent instrumentation, automotive electronic system, the weapon system, home appliances, office automation equipment, financial electronic system, toys, personal information terminals and communication products.According to its use can be divided into general type and special two kinds big.(1) universal single-chip microcomputer is the internal development resources (such as the memory and I/O, etc. Various kinds of peripheral function parts) can all to give users. Users according to the needs, design a single-chip microcomputer chip on general as the core, match again with peripheral interface circuit and other peripheral equipment, and write the corresponding software to meet the various different need of measurement and control system. Usually said and book introduces is universal microcontroller.(2) special MCU is specific to certain products and make the specific use of the microcontroller. Because the design of "special", has the most simplified structure of this system, reliability and cost optimization, etc all did comprehensive consideration, so "special" SCM has obviously comprehensive advantage.Whatever "special" purposes microcomputer in how "designed", the basic structure and working principle is based on general single-chip microcomputer.MCU development history is how to divide?SCM according to the processing binary digits mainly divided into: four microcontroller, 8-bit microcontroller, 16 SCM and 32-bit SCM. Development can be divided into four stages.The first stage (1974 ~ 1976) : SCM primary stage. Because of craft, microcontroller with double piece limited form of and the function is simple. In December 1974, XianTong company has released eight F8 microcontroller, in fact only included eight CPU, RAM and 64 B two parallel port.The second stage (1976 ~ 1978) : low performance microcontroller stage. In 1976 the MCS-48 intel-based microcontroller (eight) greatly promote the reform and development of single chip, 1977 launch of the GI PIC1650, but this stage is still at low performance stage.The third stage (1978 ~ 1983) : high performance microprocessor stage. In 1978, the Zilog Z8 microcontroller, launched in 1980, the Intel company in MCS - 48 series launched MCS - based on 51 series, 6801 microcontroller. Mortorola launch To make SCM performance and the application of the leap in the new stage.Since then, each company 8-bit microcontroller rapid development. The launch of the single chip with universal serial I/O mouth, multilevel interrupt system, and A timer/counter, within the capacity of ROM, RAM, and addressing range increased to 64 KB, some within the piece with A/D converter. Because this kind of MCU high performance-to-price, so are widely used, is currently the largest number of MCU application.The fourth stage (1983 ~ now) : 8-bit microcontroller consolidates and 16-bit single chip, 32-bit SCM launch phase. 16 typical product of the Intel company series microcontroller - 96 MCS. And 32-bit SCM, except for its higher level of integration, the data processing the 16-bit single chip improve faster than many than 8 bits, and performance 16-bit single chip more superior.1990s large development period, microcontroller manufacturing Mortorola, Intel, ATMEL, Texas instruments (TI), mitsubishi, Hitachi, philips and LG company developed a large number of the superior performance of microcontroller, push the MCU application. In recent years, and there are many new type of high level of integration of the single chip products, the products emerging in the rich and colorful situation. Currently, except 8-bit microcontroller widely used outside, the 16-bit single chip, 32-bit SCM also get broad customers.1．MCU characteristics :MCU is integrated circuit technology and microcomputer technology, high-speed development of the product. Small size, low prices and easy application, stable and reliable, and therefore, to industrial automation areas such as a major revolution andtechnology progress. For small volume, easily into the system, in order to achieve the of all kinds of test, calculation or control, this, general microcomputer cannot do. Due to the microcontroller itself is a miniature computers, so as long as the microcontroller external appropriately increase some necessary peripheral expansion circuit, it can be flexibly constitute various application system, such as industrial automatic detection monitoring system, data acquisition system, automatic control system, intelligent instruments, etc.2．The advantage of MCU(1) complete function, application and reliable, strong anti-jamming capability.(2) is simple, easy to popularize. Microcontroller technology is easy control technology. Application system design, construction, commissioning is an easy thing, engineering and technical personnel through learning can quickly grasp its application design technology.(3) the rapid development and broad prospects. Only lasts for a few decades, microcontroller after four machine, eight machine, 16-bit machine, 32-bit machine and so on several big stage of development. Especially the integration high, function ever-improving single-chip microcomputer in the market, make continuous industrial control and industrial automation area achieved great progress and lots of applications. At present, more perfect, microcontroller internal structure pieces (functional components increasingly perfect periphery, to a higher level and the development of more massive lay solid foundation.(4) embedded easy, versatility, small size, high ratio of performance, application characteristics of flexibility in embedded microcontroller control system in a very important position.SCM appear before, making a set of measurement and control system, a large number of analog circuit, digital circuit, division element complete, in order to achieve calculation, judgment and control function. The huge volume, the line system, more complex, easy failure point. SCM appears after most of, and its function by MCU software program realization, other electronic circuit consists of functional components in outer piece to replace.3．MCU application :Hardware and software integration, small volume, easily embedded in application system to all sorts. Widely used1．Industrial test and controlMain application: industrial process control and intelligent control, equipment control, data collection and transmission, test, measure, monitor, etc. In industrial automation field, electromechanical integration technology will play a more and more important role in this set machinery, microelectronics and computer technology is a body comprehensive technology (such as robotics), SCM plays a very important role.2．InstrumentsAt present automation and intelligent instruments are increasingly demanding. SCM use help to improve the accuracy and precision instrument, simplified structure, reducing the volume and easy to carry and use, accelerate instruments to digital, intelligent, muti_function change direction.3．Consumer electronic productsFor example, washing machines, refrigerators, air conditioner, electric fan, television, microwave oven, humidifying machine, alexipharmic ark, etc. Embedded microcontroller, the function and performance greatly improved, and realize intelligent, optimization control.4．CommunicationIn modem, mobile phone, fax, program-controlled telephone exchanges, information network, and all kinds of communication equipment, SCM has also been widely used.5．WeaponsIn the modern arms and equipment, such as ships, aircraft, tanks and missiles, torpedo guidance, intelligent weapons and equipment, space shuttle, navigation system, have a single chip embedded them.6．All kinds of terminal and computer external equipmentThe computer network terminal (such as banking terminal) and computer external equipment (such as printer, hard disk drives, drawing machine, electrograph, photocopiers, etc.) use a single chip microcomputer as controller.7．Automotive electronic equipmentHas been widely applied in all kinds of automobile electronic equipment, such as car safety system, automotive information system, intelligent automatic driving system, satellite car navigation system, auto emergency request service system, automotive anti-collision monitoring system, car to be automatic diagnosis system and car indestructible black box, etc.8．Distributed computer systemIn more complex of the control system, and often the distributed more machine system. General by a number of different function of single chip, their complete particular task, they through serial communication mutual connection, coordination. In this system, the microcontroller often as a terminal, installed in the system of some nodes, real-time field information of measurement and control.From industrial automation, automatic control, intelligent instruments, consumer electronic products and other aspects, until the sophisticated national defense technology field, SCM has played a very important role.4．MCU development trend :The development trend of the chip will be to large capacity and high performance-based, peripheral circuit is installed inside aspects of development. To meet the requirements of different customers, the company can meet different needs to launch the product1. The CPU improvement(1) increase CPU data bus width. For example, all sorts of 16 SCM and 32-bit SCM, data processing ability is superior to the 8-bit microcontroller. In addition, 8-bit microcontroller internal using 16-bit data bus, its data processing ability obviously better than the general 8-bit microcontroller.(2) using dual CPU, in order to improve the structure of data processing ability.2. The development of memory(1) piece inside the program memory widespread use of the blink (Flash) memory. The program memory, no need to expand, simplify system structure.(2) increasing storage capacity. At present some SCM piece inside the program memory capacity of up to 128 KB even more.3. Slice the improvement in the I/O(1) increase parallel port drive ability, to reduce the external drive chip. Some SCM can directly output large current and high voltage, so as to be able to direct drive LED and VFD fluorescence display) (.(2) some single chip set up some special serial I/O functions, a distributed network system, to provide convenient conditions.4. The low power consumptionThe low consumption, CMOS configuration have waited for state, sleep state, such as closed way to work. Consumption only in A current maximum tire-road friction coefficient, suitable for making or magnitude of portable battery power, A hand-held instruments and other consumer electronic products.5. The outer circuit is installed insideMany peripheral circuit of, that is all in the system in the single chip is the development trend of. The United States, for example, the company Cygnal C8051F020 eight microcontroller, internal structure, most of the line of instructions finishing time for 1 or 2 clock cycle peak, processing power for the MIPS 25. Chip integrated eight channel A/D, two way D/A, two road voltage comparator, built-in temperature sensor, timer, programmable digital crossover switch and 64 general I/O port, power monitoring, the watchdog, various types of serial interface (two UART, SPI), etc. A chip is a "control" system.To sum up, microcontroller is to muti_function, high performance, high speed (40), MHz clock low voltage (2.7 V can work), low power consumption, low price a few (dollars), periphery in a circuit of the program memory and within and data storage capacity increasing development direction.5．MCS-51 series microcontrollerMCS is chip company intel-based series symbols, such as MCS-48, MCS-51, MCS-96 series microcontroller. MCS-51 series is in MCS-48 series basis in the early '1980 s to be developed, is the first entering the country, and is widely used in our country the SCM mainstream variety. MCS-51 series variety, often use is basic and enhanced.Basic: 8031/8051/8751 (low power consumption type 80 C31/80 C51/87 C51) enhanced: 8032/8052/8752. Has the technical personnel for the country's familiar andmaster. In the 1980 s and 90 s, MCS-51 series in China is the most widely used type of chip. Typical products: 8031/8051/8751.8031 internal including a 8 bits CPU, RAM, 128 B 21 special function registers (SFR), four eight parallel I/O mouth, a full-duplex serial port, two 16 timer/counter, five interrupt source, but within a program memory of no, need to outside enlarge program memory chips.8051 is in 8031, on the basis of the piece and integration within 4 KB ROM as program memory. So 8051 is a program does not exceed 4 KB little system.

In this paper, using speech recognition technology and keyboard to control the importation of the integration of SCM in Sunplus SPCE061A achieve a voice on the electronic certification system password lock.2 voice electronic password-lock systemThis system is mainly composed of Sunplus SPCE061A SCM, MIC input circuit, voice output circuit, 4 × 4 keyboard, six Qiduan LED display and output control and FLASH memory components. System is the main function: the training, the speaker's voice through a microphone into the speaker voice signal acquisition front-end circuit, by voice signal processing circuit on the acquisition of the characteristics of voice signals and voice processing, from the speaker's personality characteristics and parameters Store, a speaker parameters database. In recognition, will be voice recognition and speaker parameters database matching, voice recognition and complete control of the keyboard, and activate or release of locks, the final completion of the lock. System is relying on hardware and software to closely cooperate with the Sunplus SPCE061A SCM flexible control achieved.Voice entry due to the interference of external environment, it is possible errors, but through a number of training can make comparison and identification of voice greatly improved3 system hardware designThe system using a single kernel of Sunplus SPCE061A, the chip has ADC, DAC, timer / counter, RAM, FLASH, and other devices, coupled with appropriate external circuit and supporting Sunplus company's integrated development environment, Can easily complete the design of hardware and software programming, thus achieving the above-mentioned functions. Voice electronic code lock system is the core of speech recognition module.SPCE061A is Sunplus has developed a very high price of the 16-bit microcontroller, embedded 2 K word of SRAM and 32 K word FLASH, with 32 programmable multi-purpose I / O ports include 7 Channel 1 O-General A / D converter, built-in microphone amplifier, AGC AGC function of the single voice of A / D converter, and the audio output of the dual-channel 1 O-bit D / A converter in the 2.6 V ~ - 3.6V operating range of frequency range of 0.32 MHz ~ - 49.152Mhz, high processing speed enable it to easily and quickly handle complex digital signal; suspension system to support 1 O interrupt vector And l4 from the system can be a clock, timer / counter, time benchmark generator, external interrupt, key wake-up call, Universal Asynchronous serial communication and software interruption interrupt source, Very suitable for real-time applications; u'nSPTM command system also provides high computing speed of 16 × 16-bit multiplication instructions and directives within the plot operation, the DSP for the application of additional features in a complex digital signal processing both Very convenient than the DSP chip for much cheaper.3.1 voice input circuitSPCE061A built-in 8-channel 1 O-bit A / D converter, which will be seven channels for analog signals (such as voltage signal) converted to digital signals, a channel used only for voice input, through the built-in automatic gain control amplifier The microphone channels (MIC-IN) input. Therefore, it can be directly given to the voice signal input channels, the completion of 8 kHz voice signals in the collection, encoding and storage to off-chip FLASH, simplifying the circuit design.✧ 3.2 audio output circuitSunplus SPCE061A MCU with audio output of dual-channel 1 O-bit D / A converters can complete user training, identification of various operations, such as the voice prompts. SPCE061A provide audio loseA way for the dual-channel DAC, in this manner, DAC1 and DAC2 conversion ofanalog current output signal passed AUD1 and AUD2-pin output, enter the number of volume into the P-DAC1 (write) (0 x7017) and P - DAC2 (write) (0 x7016) unit.✧ 3.3 six Qiduan display of digital circuitsLED displays in each LED through 5 ~ 20mA current to achieve the normal brightness, and the IO I SPCEO61A output current up to 5 mA, do not have to drive circuit to reach normal brightness. In order to meet the reliability of systems design, driven by a transistor circuit. The whole process showed that the use of dynamic, that is, six monitors each cycle, each sustained lms or 10 ms cycle again, can also be appropriate to make changes, but the refresh rate not less than 30 per second, so that temporary stay because of the visual phenomenon , Is six Qiduan see the LED display at the same time show.✧ 3.4 Matrix keyboard scan circuitEnter key part of a total of the number keys, passwords, keys set, the key shown password, to confirm removal of keys and passwords, and other key 16 keys, enter your password and for the realization of function keys. This design uses a wake-up function keys of the IO low eight IOA0 - ~ IOA7 to 4 × 4 as the control input of the keyboard, which can be rational use of hardware resources and programming flexibility. Recognition keyboard keys are pressed whether the method is: Let all out lines are low, check the traffic on whether there is a high-level, if there is a statement that a key is pressed, if not, then no keys are pressed (Actual programming keys should be taken into account the impact of jitter, usually always use the software delay processing methods Consumers buffeting).Identify specific keys used scanning method: home-by-zero level out and check the level of the carriageway of the changes, if a line from the low level into a high, this trip can be sure this column cross-point Button is pressed.✧ 3.5 FLASH expansion of external circuitSPCEO61A FLASH memory chip of only 32 K, large number of players in thevoice of resources needs of expanding memory. The design Sunplus Technology, Inc., SPR4096 as a memory expansion, combined with SPCE061A broadcast voice.SPR4096 in use, the use of SPR4096 ResWriter to read and write operation, used to store the speaker's personality parameters reference template.3.6 the lock and lift activationSCM SPCE061A complete identification and display, the drive to realize the implementation of the electromagnetic lock function, and to detect its drive current value, to receive alarm signals sent by sensors, such as sending data. SCM receive the type code, and stored in FLASH in the password, if the correct password, the drive for the implementation of the electromagnetic lock, if your password is not correct, allowing operators to re-enter your password, can enter up to three If the three are not correct, the MCU through intelligent communication lines to monitor the police. SCM will unlock operation and each time the electromagnetic actuator drive current value as a status information sent to the smart monitor, will receive the report from the sensor interface information is also sent to the intelligent monitoring, as smart Analysis of the basis. In the transmitter, electronic locks through the pulse transformer T will modulation good boost after data signals sent out in the receiver, pulse transformer T will receive the data signal demodulator buck evacuation to reduce the carrier signal transmission In the process of wear and tear. In order to reduce communication and mutual interference between the power supply, chokes L, the choice of coupling capacitance C to comprehensive considerations, shown in Figure 4, a carrier frequency f0-400kHz, in order to ensure that most of the energy transmission signal to the receiver Duan, L for a 33.7 H, C1-0.047 ~ F.Current surveillance function is to prevent the destruction of communication lines and electromagnetic actuator, for some reason the flow of electromagnetic coil currents too large burning coil. Current Monitor by MAXIM company's current / voltage converter chip MAX471. The chip can be measured current I into pairs to the output voltage U, and is measured Wai, high precision, and U output voltage proportional to the measured current I characteristics. Current monitor output voltage service A / D converter, read through the single A / D converter results in the current line was informed of the situation, through the timely detection of abnormal, issued its report.4 system software designSPCE061A the development of online debugger PROBE To achieve. It uses a built-in online SPCE061 Circuit Simulation ICE (In-Circuit Emulator) and Sunplus's online series Line programming. PROBE can work in Sunplus IDE Integrated Development Environmental software nSP (tm), with editing, compile, link, debug and simulation capabilities. Use IDE friendly interface, the drop-down menu, shortcuts and quick access to the list can be ordered so that the user's programming and commissioning work more convenient and efficient.
