Electronic lockFrom Wikipedia, the free encyclopedia An electronic lock (more precisely an electric lock ) is a locking device which operates by means of electric current. Electric locks are sometimes stand-alone with an electronic control assembly mounted directly to the lock. More often electric locks are connected to an access control system. The advantages of an electric lock connected to an access control system include: key control, where keys can be added and removed without re-keying the lock cylinder; fine access control, where time and place are factors; and transaction logging, where activity is recorded.The most basic type of electronic lock is a magnetic lock (commonly called a mag lock). A large electro-magnet is mounted on the door frame and a corresponding armature is mounted on the door. When the magnet is powered and the door is closed, the armature is held fast to the magnet. Mag locks are simple to install and are very attack resistant. One drawback is that improperly installed or maintained mag locks can fall on people. and also that one must unlock the mag lock to both enter and leave. This has caused fire marshals to impose strict codes on the use of mag locks and the access control practice in general. Additionally, NFPA 101, Standard for Life Safety and Security, as well as the ADA (Americans with Disability Act) require "no prior knowledge" and "one simple movement" to allow "free egress". This means that a person must be able to walk up to a door and with one motion (no push buttons, or having another person unlock the door, or read a sign "special knowledge") and exit. Other problems include a lag time (delay) in releasing as the collapsing magnetic field is not instantaneous. This lag time can cause a user to walk into the door. Finally, mag locks by design fail unlocked, that is if power is removed they unlock. This could be a problem where security is a prime concern. Additionally, power outages could affect mag locks installed on fire listed doors, which are required to remain latched at all times. Thus, a mag lock would not meet current fire codes as the primary means of securing a fire listed door to aframe [ 1 ] . Because of this, many commercial doors (this typically does not apply to private residences) are moving over to stand alone locks, or electric locks installed under a Certified Personnel Program. The first mechanical recodable card lock was invented in 1976 by TorSørnes , who had worked for VingCard since the 1950s. The first card lock order was shipped in 1979 to Westin Peachtree Plaza Hotel , Atlanta, USA. This product triggered the evolution of electronic locks for the hospitality industry.Electric strikes (also called electric latch release) replace a standard strike mounted on the door frame and receive the latch and latch bolt. Electric strikes can be simple to install when they are designed for drop-in replacement of a standard strike, although some electric strikes require that the door frame be heavily modified. Installation of a strike into a Fire ListedDoor (for open backed strikes on pairs of doors) or Frame must be done under listing agency authority if any modifications to the frame are required (mostly for commercial doors andframes). Since there is no current Certified Personnel Program to allow field install ation of electric strikes into fire listed door openings, listing agency field evaluations would most likely require the door and frame to be de-listed and replaced. Electric strikes allow mechanical free egress: As a user leaves, he operates the lockset in the door, not the electric strike in the door frame. Electric strikes can also be either fail unlocked (except in Fire Listed Doors, as they must remain latched when power is not present), as a mag lock, or the more secure fail locked. Electric strikes are easier to attack than a mag lock. It is simple to lever the door open at the strike, as often there is an increased gap between the strike and the door latch. Latch guards are often used to cover this gap.Electric mortise and cylindrical locks are drop in replacements for the door mounted mechanical locks. A hole must be drilled in the door for electric power wires. Also a power transfer hinge [ 2 ] is used to get the power from the door frame to the door. Electric mortise and cylindrical locks allow mechanical free egress. Electric mortise and cylindrical locks can be either fail unlocked or fail locked. In the US, UL rated doors must retain their rating. In new construction doors are cored and then rated. In retofits, the doors must be re-rated. Electrified exit hardware, sometimes called panic hardware or crash bars, are used in fire exit applications. One pushes against the bar to open it, making it the easiest of mechanically free exit methods. Electrified exit hardware can be either fail unlocked or fail locked. A drawback of electrified exit hardware is their complexity which requires skill to install and maintenance to assure proper function. Only hardware labeled "Fire Exit Hardware" can be installed on fire listed doors and frames and must meet both Panic Exit listing Standards and Fire listing Standards.Motor operated locks are used throughout Europe. A European motor operated lock has two modes, day mode where only the latch is electrically operated, and night mode where the more secure deadbolt is electrically operated.Numerical codes, passwords and passphrasesPerhaps the most prevalent form of electronic lock is that using a numerical code for authentication; the correct code must be entered in order for the lock to deactivate. Such locks typically provide a keypad, and some feature an audible response to each press. Combination lengths are usually between 4 and 6 digits long.A variation on this design involves the user entering the correct password or passphrase . Security tokensAnother means of authenticating users is to require them to scan or "swipe" a securitytoken such as a smart card or similar, or to interact a token with the lock.

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. The circuit of the system is required by AT89C51 chip, clock circuit, reset circuit, driving circuit, scanning line5driving circuit and LCD1602 LCD screen. 4*4 matrix keyboard accessof P1.0 —P1.7,LCD 1602 screen to access P0.0—P0.7.3 System hardware circuit design3.1 Liquid crystal moduleThe principle of liquid crystal display is the use of physical properties of liquid crystal, The display control area voltage, power is displayed, it can display graphics. 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. And all kinds of new technology, as a single field of the new method, the development trend of new products and symbol -- intelligent significantly is one of the trends in development. The module design display microcontroller matrix keyboard and LCD, make us understand8to this technology innovation, through in-depth study on this technology, we can master the use in other areas, such as the design of electronic password lock, adjustment and control of indoor temperature and humidity, field access control system design etc..

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.

电子密码锁英语翻译

An electronic lock (more precisely an electric lock) is a locking device which operates by means of electric current. Electric locks are sometimes stand-alone with an electronic control assembly mounted directly to the lock. More often electric locks are connected to an access control system. The advantages of an electric lock connected to an access control system include: key control, where keys can be added and removed without re-keying the lock cylinder; fine access control, where time and place are factors; and transaction logging, where activity is recorded.Contents [hide]1 Operation2 Types of electric locks3 Authentication methods3.1 Numerical codes, passwords and passphrases3.2 Security tokens3.3 Biometrics3.4 RFID4 See also5 References[edit]OperationElectric locks use magnets, solenoids, or motors to actuate the lock by either supplying or removing power. Operating the lock can be as simple as using a switch, for example an apartment intercom door release, or as complex as a biometric based access control system.[edit]Types of electric locksThis article may contain original research. Please improve it by verifying the claims made and adding references. Statements consisting only of original research may be removed. More details may be available on the talk page. (June 2008)This article uses first-person ("I"; "we") or second-person ("you") inappropriately. Please rewrite it to use a more formal, encyclopedic tone. (June 2008)The most basic type of electronic lock is a magnetic lock (commonly called a mag lock).A large electro-magnet is mounted on the door frame and a corresponding armature is mounted on the door. When the magnet is powered and the door is closed, the armature is held fast to the magnet. Mag locks are simple to install and are very attack resistant. One drawback is that improperly installed or maintained mag locks can fall on people. and also that one must unlock the mag lock to both enter and leave. This has caused fire marshals to impose strict codes on the use of mag locks and the access control practice in general. Additionally, NFPA 101, Standard for Life Safety and Security, as well as the ADA (Americans with Disability Act) require "no prior knowledge" and "one simple movement" to allow "free egress". This means that a personmust be able to walk up to a door and with one motion (no push buttons, or having another person unlock the door, or read a sign "special knowledge") and exit. Other problems include a lag time (delay) in releasing as the collapsing magnetic field is not instantaneous. This lag time can cause a user to walk into the door. Finally, mag locks by design fail unlocked, that is if power is removed they unlock. This could be a problem where security is a prime concern. Additionally, power outages could affect mag locks installed on fire listed doors, which are required to remain latched at all times. Thus, a mag lock would not meet current fire codes as the primary means of securing a fire listed door to a frame[1]. Because of this, many commercial doors (this typically does not apply to private residences) are moving over to stand alone locks, or electric locks installed under a Certified Personnel Program. The first mechanical recodable card lock was invented in 1976 by Tor S?rnes, who had worked for VingCard since the 1950s. The first card lock order was shipped in 1979 to Westin Peachtree Plaza Hotel, Atlanta, USA. This product triggered the evolution of electronic locks for the hospitality industry.Electric strikes (also called electric latch release) replace a standard strike mounted on the door frame and receive the latch and latch bolt. Electric strikes can be simple to install when they are designed for drop-in replacement of a standard strike, although some electric strikes require that the door frame be heavily modified. Installation of a strike into a Fire Listed Door (for open backed strikes on pairs of doors) or Frame must be done under listing agency authority if any modifications to the frame are required (mostly for commercial doors and frames). Since there is no current Certified Personnel Program to allow field installation of electric strikes into fire listed door openings, listing agency field evaluations would most likely require the door and frame to be de-listed and replaced. Electric strikes allow mechanical free egress: As a user leaves, he operates the lockset in the door, not the electric strike in the door frame. Electric strikes can also be either fail unlocked (except in Fire Listed Doors, as they must remain latched when power is not present), as a mag lock, or the more secure fail locked. Electric strikes are easier to attack than a mag lock. It is simple to lever the door open at the strike, as often there is an increased gap between the strike and the door latch. Latch guards are often used to cover this gap.Electric mortise and cylindrical locks are drop in replacements for the door mounted mechanical locks. A hole must be drilled in the door for electric power wires. Also a power transfer hinge[2] is used to get the power from the door frame to the door. Electric mortise and cylindrical locks allow mechanical free egress. Electric mortise and cylindrical locks can be either fail unlocked or fail locked. In the US, UL rated doors must retain their rating. In new construction doors are cored and then rated. In retofits, the doors must be re-rated.Electrified exit hardware, sometimes called panic hardware or crash bars, are used in fire exit applications. One pushes against the bar to open it, making it the easiestof mechanically free exit methods. Electrified exit hardware can be either fail unlocked or fail locked. A drawback of electrified exit hardware is their complexity which requires skill to install and maintenance to assure proper function. Only hardware labeled "Fire Exit Hardware" can be installed on fire listed doors and frames and must meet both Panic Exit listing Standards and Fire listing Standards.Motor operated locks are used throughout Europe. A European motor operated lock has two modes, day mode where only the latch is electrically operated, and night mode where the more secure deadbolt is electrically operated.[edit]Authentication methodsA biometric electronic lock with PIN entry.Electronic locks offer a variety of means of authentication; those described below are not considered exhaustive.[edit]Numerical codes, passwords and passphrasesPerhaps the most prevalent form of electronic lock is that using a numerical code for authentication; the correct code must be entered in order for the lock to deactivate. Such locks typically provide a keypad, and some feature an audible response to each press. Combination lengths are usually between 4 and 6 digits long.A variation on this design involves the user entering the correct password or passphrase.[edit]Security tokensAnother means of authenticating users is to require them to scan or "swipe" a security token such as a smart card or similar, or to interact a token with the lock. For example, some locks can access stored credentials on a personal digital assistant (PDA) using infrared data transfer methods.[edit]BiometricsAs biometrics become more and more prominent as a recognized means of positive identification, their use in security systems increases. Some new electronic locks take advantage of technologies such as fingerprint scanning, retinal scanning and iris scanning, and voiceprint identification to authenticate users.[edit]RFIDRadio-frequency identification (RFID) is the use of an object (typically referred to as an RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader. This technologyis also used in modern electronic locks.。

单片机也被称为微控制器（Microcontroller），是因为它最早被用在工业控制领域。

单片机由芯片内仅有CPU的专用处理器发展而来。

最早的设计理念是通过将大量外围设备和CPU集成在一个芯片中，使计算机系统更小，更容易集成进复杂的而对体积要求严格的控制设备当中。

INTEL的Z80是最早按照这种思想设计出的处理器，从此以后，单片机和专用处理器的发展便分道扬镳。

早期的单片机都是8位或4位的。

其中最成功的是INTEL 的8031，因为简单可靠而性能不错获得了很大的好评。

此后在8031上发展出了MCS51系列单片机系统。

基于这一系统的单片机系统直到现在还在广泛使用。

随着工业控制领域要求的提高，开始出现了16位单片机，但因为性价比不理想并未得到很广泛的应用。

90年代后随着消费电子产品大发展，单片机技术得到了巨大提高。

随着INTEL i960系列特别是后来的ARM系列的广泛应用，32位单片机迅速取代16位单片机的高端地位，并且进入主流市场。

而传统的8位单片机的性能也得到了飞速提高，处理能力比起80年代提高了数百倍。

目前，高端的32位单片机主频已经超过300MHz，性能直追90年代中期的专用处理器，而普通的型号出厂价格跌落至1美元，最高端[1]的型号也只有10美元。

当代单片机系统已经不再只在裸机环境下开发和使用，大量专用的嵌入式操作系统被广泛应用在全系列的单片机上。

而在作为掌上电脑和手机核心处理的高端单片机甚至可以直接使用专用的Windows和Linux 操作系统。

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 keyboard1 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. SCM2has 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/D converter, 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 key3information processing functions after the show. The circuit of the system is required by AT89C51 chip, clock circuit, reset circuit, driving circuit, scanning line driving circuit and LCD1602 LCD screen. 4*4 matrix keyboard access of P1.0 —P1.7,LCD 1602 screen to access P0.0—P0.7.3 System hardware circuit design3.1 Liquid crystal moduleThe principle of liquid crystal display is the use of physical properties of liquid crystal, The display control area voltage, power is displayed, it can display graphics. 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 module display characters and numbers).3.2 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 a4dither. 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 designThe 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 Conclusion5With the continuous development of high and new technology, the miniaturization and the miniaturization of electronic products has been achieved. And all kinds of new technology, as a single field of the new method, the development trend of new products and symbol -- intelligent significantly is one of the trends in development. The module design display microcontroller matrix keyboard and LCD, make us understand to this technology innovation, through in-depth study on this technology, we can master the use in other areas, such as the design of electronic password lock, adjustment and control of indoor temperature and humidity, field access control system design etc.. Technological progress and economic development are the main themes of the present era, the improvement of people's living standard is bound to the requirements of electronic products increase, the design of any a small system is for a foundation, design of system innovation, the hardware, software integration, method and technology of virtual display and soft measurement artificial intelligence, I firmly believe that our life will be more colourful.6基于单片机的矩阵键盘与液晶显示的设计摘要微电子技术的发展和工业测量的需求，给系统的开发及深入研究带来了良好的契机，发展前景广阔。
