基于单片机的万年历时钟设计【文献综述】
毕业设计开题报告测控技术与仪器基于单片机的万年历时钟设计1前言部分在当代繁忙的工作与生活中，时间与我们每一个人都有非常密切的关系，每个人都受到时间的影响。
为了更好的利用我们自己的时间，需要一款灵活、稳定而又功能强大的自动定时控制系统，以规范本单位的作息时间或定时控制一些设备。
目前，市面上出现的一些时控设备或功能单一，或使用烦琐，或价格昂贵，总有一些不尽如人意的地方[1]。
我们必须对时间有一个度量，因此产生了钟表。
钟表的发展是非常迅速的，17 世纪中叶, 由荷兰人C. Huygens来发明的第一个钟摆与以前任何计时装置相比, 摆钟的精确度提高了上百倍,而他随后发明的螺旋平衡弹簧,又进一步提高精度、减小体积, 导致了怀表的出现。
然而再好的摆钟,其精度也只能达到每年误差不超过一秒[2]。
1939年出现了利用石英晶体振动计时的石英钟, 每天误差只有千分之二秒, 到二次大战后精度提高到30 年才差一秒。
很快, 测年的技术又推进到原子层面, 1948 年出现第一台原子钟, 1955年又发明了铯原子钟, 利用Cs133原子的共振频率计时,现在精度已经高达每天只差十亿分之一秒[2]。
从刚开始的机械式钟表到现在普遍用到的数字式钟表，即使现在钟表千奇百怪，但是它们都只是完成一种功能——计时功能，只是工作原理不同而已，在人们的使用过程中，逐渐发现了钟表的功能太单一，无法更大程度上的满足人们的需求。
发展到现在人们广泛使用的万年历。
万年历在家庭居室、学校、车站和广场使用越来越广泛，给人们的生活、学习、工作带来极大的方便[3]。
电子万年历具有信息量大、直观清晰、经济实用等优点，正成为家庭、商场、公共场所等新的消费热点，具有重要的开发价值[4]。
随着科技的不断发展，家用电子产品不但种类日益丰富，而且变得更加经济实用，，功能也越来越齐全，除了公历年月、日、时分秒、星期显示及闹铃外，又增加了农历、温度、24节气及l2生肖等显示。

A keypad control circuit (3) consists of several keys for entering the date information to the central processing unit (20) for converting the entered date to the corresponding Chinese Lunar Calendar date or National Calendar of R.O.C./Gregorian Calendar date. Both the entered and converted date will be displayed on the corresponding display units on the display screen (12). The user can use this invention to find out the corresponding Chinese Lunar Calendar date or National Calendar of R.O.C./Gregorian Calendar date in the past or future.The keypad control circuit (3) of this invention consists of the following keys: two "YEAR/HOUR" keys (31,31') for increasing/decreasing the setting of YEAR display unit (121); two "MONTH/MINUTE" keys (32,32') for increasing/decreasing the setting of MONTHdisplay unit (122); two "DAY" keys (33,33') for increasing/decreasing the setting of DAY display unit (123); an alarm pre-set key (34) is used for setting up multiple sets of alarm time, the alarm time will be stored in the memory of central processing unit (20), the audio integrated circuit will be triggered to broadcast music or Buddhist information through loudspeaker(35) when the information from time control circuit(21) is the same as the pre-set alarm time; one National Calendar of R.O. C./Gregorian Calendar switch over key (36) is used to switch the YEAR display unit (121) from one to another.When the electronic calendar is powered on, the current date in both the Chinese Lunar Calendar and Gregorian Calendar format will be displayed on the display screen. As shown in FIG. 1, the date is Thursday, Apr. 18th of the 85th year of R.O.C., the corresponding Chinese Lunar Calendar date is the 1st day of the third month (this is a short month) of the year and the time is 12 o'clock.. If "YEAR/HOUR" key(31')、"MONTH/MINUTE" key (32) and "DAY" key (33') are pressed to change the date to the 8th day of October of the 84th year of R.O.C., the corresponding Chinese Lunar Calendar will be changed to the 14th day of the intercalary month of the eighth month (short month) of the year. Similarly, the user can find out the Chinese Lunar Calendar date of desired National Calendar of R.O.C./Gregorian Calendar date instantly by pressing the appropriate keys and both the entered date and the corresponding Lunar Calendar date are displayed on the same display screen (12).As this electronic calendar can display the date of National Calendar of R.O.C. and the corresponding date of the Chinese Lunar Calendar on the display screen (12) at the same time, it can be used to perform conversion between the Chinese Lunar Calendar date and of National Calendar of R.O.C./Gregorian Calendar date, and to support two types of alarm notifications (based on pre-set hour and minute and based on the pre-set date). It is obvious that this electronic calendar is superior to the commonly available electronic calendars.With reference to FIG. 5 showing the circuit diagram of this invention, the timing control circuit (21) sends timing information to the central processing unit (20) which will process the incoming information from timing control circuit (21) and send the output information to converter (22). Then, the converter (22) will convert the information from central processing unit (20) into display signal for the display units. The display signal from converter (22) will cooperate with the display/keypad scanner circuit (23) for displaying the information on the corresponding display units on the display screen (12). The displayed information includes year, month and day of National Calendar of R.O.C./Gregorian Calendar, month and day of the Chinese Lunar Calendar, day of week, hour and minute. The central processing unit (20) will also receive key-in information from the keypad control circuit (3) and the received information will be processed to produce the corresponding Chinese Lunar Calendar date and National Calendar of R.O.C. date information. The information will be displayed on the corresponding display units on display screen (12) through the cooperation of converter (22) and display/keypad scanner circuit (23). An alarm notification may be pre-set by pressing the keys of keypad control circuit (3) and the pre-set alarm is stored in the memory of central processing unit (20).The audio integrated circuit will be triggered to broadcast a voice through loudspeaker (35) to notify user of the arrival of the pre-set time/date when the time/date information from timing control circuit matches with the pre-set alarm time/date .Referring to FIG.6，the logic Bow of the present invention will be described as follows:The calendar starts to run after power is switched on and the system will perform initial valueinput and output to decide if information is updated or not. If information update is true, enter new information, and if new information is read, then update the Chinese Lunar Calendar and National Calendar of R.O.C. information and the corresponding display information, update and scan the display units of display screen display units to reflect the entered new information, update the day of week information, scan the keypad for any input information If input information is detected, then determine which function is requested. If the requested function is calendar date conversion, then convert the information to corresponding National Calendar of R.O.C. and the Chinese Lunar Calendar information and send the converted information to the corresponding display units on the display screen. If the requested function is setting of alarm type "1", allow the pre-setting of multiple daily alarms. If the requested function is setting of alarm type "2", allow the date alarm setting. When the date information of timing control circuit is the same as the pre-set date, the audio integrated circuit will be triggered to broadcast voice information through loudspeaker to notify the user.The keypad control circuit (3) consists of an alarm reset key (37) for resetting the signal for triggering the loudspeaker (35), so that the audio alarm is interrupted (cleared).In conclusion, the present invention has the following advantages:1. This invention can display the date of the Chinese Lunar Calendar, date of National Calendarof R.O.C./Gregorian Calendar, year, day of week and time on the same display screen at the same time.2. This invention provides instant date conversion between date of Lunar Calendar and date ofNational Calendar of R.O.C./Gregorian Calendar and both the date for conversion and the converted date are displayed on the same display screen at the same time, so that the user can find out; the National Calendar of R.O.C/Gregorian Calendar date and its corresponding Lunar Calendar date without the need of the switchover of display screen.3. This invention provides multiple calendar information (the Chinese Lunar Calendar, NationalCalendar of R.O.C. and Gregorian Calendar) used for Chinese custom. It can be used for years and as replacement of the use of printed paper calendar, so that less paper is used and better environment protection is achieved.4. This invention supports the pre-set of multiple time and date alarm notification. When thepre-set time/date is arrived, an audio notification is created to notify the user. This feature is quite suitable for notifying the user of the important date, activity,…etc.原文题目： Electronic calendar 译文题目：电子日历电子日历的背景1．发明的领域本发明是有关中国阳历和阴历之间相互转化的一个电子日历。
基于AT89S52单片机和DS1302的电子万年历设计英文翻译
英文翻译OverviewThe 8051 family of micro controllers is based on an architecture which is highly optimized for embedded control systems. It is used in a wide variety of applications from military equipment to automobiles to the keyboard on your PC. Second only to the Motorola 68HC11 in eight bit processors sales, the 8051 family of microcontrollers is available in a wide array of variations from manufacturers such as Intel, Philips, and Siemens. These manufacturers have added numerous features and peripherals to the 8051 such as I2C interfaces, analog to digital converters, watchdog timers, and pulse width modulated outputs. Variations of the 8051 with clock speeds up to 40MHz and voltage requirements down to 1.5 volts are available. This wide range of parts based on one core makes the 8051 family an excellent choice as the base architecture for a company's entire line of products since it can perform many functions and developers will only have to learn this one platform.The basic architecture consists of the following features:12which can be individually accessed34567paces for DA TA and CODE memoryOne 8051 processor cycle consists of twelve oscillator periods. Each of the twelve oscillator periods is used for a special function by the 8051 core such as op code fetches and samples of the interrupt daisy chain for pending interrupts. The time required for any 8051 instruction can be computed by dividing the clock frequency by 12, inverting that result and multiplying it by the number of processor cycles required by the instruction in question. Therefore, if you have a system which is using an 11.059MHz clock, you can compute the number of instructions per second by dividing this value by 12. This gives an instruction frequency of 921583 instructions per second. Inverting this will provide the amount of time taken by each instruction cycle (1.085 microseconds).Memory OrganizationThe 8051 architecture provides the user with three physically distinct memory spaces which can be seen in Figure A - 1. Each memory space consists of contiguous addresses from 0 to the maximum size, in bytes, of the memory space. Address overlaps are resolved by utilizing instructions which refer specifically to a given address space. The three memory spaces function as described below.The CODE SpaceThe first memory space is the CODE segment in which the executable program resides. This segment can be up to 64K (since it is addressed by 16 address lines) . The processor treats this segment as read only and will generate signals appropriate to access a memory device such as an EPROM. However, this does not mean that the CODE segment must be implemented using an EPROM. Many embedded systems these days are using EEPROM which allows the memory to be overwritten either by the 8051 itself or by an external device. This makes upgrades to the product easy to do since new software can be downloaded into the EEPROM rather than having to disassemble it and install a new EPROM. Additionally, battery backed SRAM can be used in place of an EPROM. This method offers the same capability to upload new software to the unit as does an EEPROM, and does not have any sort of read/write cycle limitations such as an EEPROM has. However, when the battery supplying the RAM eventually dies, so does the software in it. Using an SRAM in place of an EPROM in development systems allows for rapid downloading of new code into the target system. When this can be done, it helps avoid the cycle of programming/testing/erasing with EPROM, and can also help avoid hassles over an in circuit emulator which is usually a rare commodity.In addition to executable code, it is common practice with the 8051 to store fixed lookup tables in the CODE segment. To facilitate this, the 8051 provides instructions which allow rapid access to tables via the data pointer (DPTR) or the program counter with an offset into the table optionally provided by the accumulator. This means that oftentimes, a table's base address can be loaded in DPTR and the element of the table to access can be held in the accumulator. The addition is performed by the 8051 during the execution of the instruction which can save many cycles depending on the situation. An example of this is shown later in this chapter in.The DATA SpaceThe second memory space is the 128 bytes of internal RAM on the 8051, or the first 128 bytes of internal RAM on the 8052. This segment is typically referred to as the DA TA segment. The RAM locations in this segment are accessed in one or two cycles depending on the instruction. This access time is much quicker than access to the XDA TA segment because memory is addressed directly rather than via a memory pointer such as DPTR which must first be initialized. Therefore, frequently used variables and temporary scratch variables are usually assigned to the DATA segment. Such allocation must be done with care, however, due to the limited amount of memory in this segment.V ariables stored in the DATA segment can also be accessed indirectly via R0 or R1. The register being used as the memory pointer must contain the address of the byte to be retrieved or altered. These instructions can take one or two processor cycles depending on the source/destination data byte.The DATA segment contains two smaller segments of interest. The first sub segment consists of the four sets of register banks which compose the first 32 bytes of RAM. The 8051 can use any of these four groups of eight bytes as its default register bank. The selection of register banks is changeable at any time via the RS1 and the RS0 bits in the Processor Status Word (PSW). These two bits combine into a number from 0 to 3 (with RS1 being the most significant bit) which indicates the register bank to be used. Register bank switching allows not only for quick parameter passing, but also opens the door for simplifying task switching on the 8051.The second sub-segment in the DA TA space is a bit addressable segment in which each bit can be individually accessed. This segment is referred to as the BDA TA segment. The bit addressable segment consists of 16 bytes (128 bits) above the four register banks in memory. The 8051 contains several single bit instructions which are often very useful in control applications and aid in replacing external combinatorial logic with software in the 8051 thus reducing parts count on the target system. It should be noted that these 16 bytes can also be accessed on a "byte-wide" basis just like any other byte in the DATA space.Special Function RegistersControl registers for the interrupt system and the peripherals on the 8051 are contained in internal RAM at locations 80 hex and above. These registers are referred to as special functionRegisters (or SFR for short). Many of them are bit addressable. The bits in the bit addressable SFR can either be accessed by name, index or bit address. Thus, you can referto the EA bit of the Interrupt Enable SFR as EA, IE.7, or 0AFH. The SFR control things such as the function of the timer/counters, the UART, and the interrupt sources as well as their priorities. These registers are accessed by the same set of instructions as the bytes and bits in the DATA segment. A memory map of the SFRS indicating the registers..The IDATA Spac eCertain 8051 family members such as the 8052 contain an additional 128 bytes of internal RAM which reside at RAM locations 80 hex and above. This segment of RAM is typically referred to as the IDATA segment. Because the IDA TA addresses and the SFR addresses overlap, address conflicts between IDATA RAM and the SFRs are resolved by the type of memory access being performed, since the IDA TA segment can only be accessed via indirect addressing modes.The XDATA Space.The final 8051 memory space is 64K in length and is addressed by the same 16 address lines as the CODE segment. This space is typically referred to as the external data memory space (or the XDA TA segment for short). This segment usually consists of some sort of RAM (usually an SRAM) and the I/O devices or external peripherals to which the 8051 must interface via its bus. Read or write operations to this segment take a minimum of two processor cycles and are performed using either DPTR, R0, or R1. In the case of DPTR, it usually takes two processor cycles or more to load the desired address in addition to the two cycles required to perform the read or write operation. Similarly, loading R0 or R1 will take minimum of one cycle in addition to the two cycles imposed by the memory access itself. Therefore, it is easy to see that a typical operation with the XDA TA segment will, in general, take a minimum of three processor cycles. Because of this, the DA TA segment is a very attractive place to store any frequently.It is possible to fill this segment entirely with 64K of RAM if the 8051 does not need to perform any I/O with devices in its bus or if the designer wishes to cycle the RAM on and off when I/O devices are being accessed via the bus. Methods for performing this technique will be discussed in chapters later in this book.On-Board Timer/CountersThe standard 8051 has two timer/counters (other 8051 family members have varying amounts), each of which is a full 16 bits. Each timer/counter can be function as a freerunning timer (in which case they count processor cycles) or can be used to count falling edges on the signal applied to their respective I/O pin (either T0 or T1). When used as a counter, the input signal must have a frequency equal to or lower than the instruction cycle frequency divided by 2 (ie: the oscillator frequency /24) since the incoming signal is sampled every instruction cycle, and the counter is incremented only when a 1 to 0 transition is detected (which will require two samples). If desired, the timer/counters can force a software interrupt when they overflow.The TCON (Timer Control) SFR is used to start or stop the timers as well as hold the overflow flags of the timers. The TCON SFR is detailed below in Table A - 7. The timer/counters are started or stopped by changing the timer run bits (TR0 and TR1) in TCON. The software can freeze the operation of either timer as well as restart the timers simply by changing the Trx bit in the TCON register. The TCON register also contains the overflow flags for the timers. When the timers overflow, they set their respective flag (TF0 or TF1) in this register. When the processor detects a 0 to 1 transition in the flag, an interrupt occurs if it is enabled. It should be noted that the software can set or clear this flag at any time. Therefore, an interrupt can be prevented as well as forced by the software.Microcomputer interfaceA microcomputer interface converts information between two forms .Outside the microcomputer the information handled by an electronic system exists as a physical signals, but within the program , it is represented numerically . The function of any interface can be broken down into a number of operations which modify the data in some way ,so than the process of conversion between the external and internal forms is carried out in a number or steps.This can be illustrated by means of an example such as than or Fig 10-1,which shows an interface between a microcomputer and a transducer producing a continuously variable analog signal. transducers often produce very small out requiring amply frication, or they may generate signals .in a form that needs to be converted again before being handled by the rest of the system .For example ,many transducers these variable resistance which must be converted to a voltage by a special circuit. This process of converting the transducer output into a voltage4 signal which can be connected to the rest of the system is called signal conditioning .In the example of Figure 10-1, the sigma conditioning section translates the range lf voltage or current signals from the transducer to one which can be converted to digital forum by an analog-to-digital converter.。

为了更好的利用我们自己的时间，我们必须对时间有一个度量，因此产生了钟表。
钟表的发展是非常迅速的，从刚开始的机械式钟表到现在普遍用到的数字式钟表，即使现在钟表千奇百怪，但是它们都只是完成一种功能——计时功能，只是工作原理不同而已，在人们的使用过程中，逐渐发现了钟表的功能太单一，没有更大程度上的满足人们的需求。
因此在这里，我想能不能把一些辅助功能加入钟表中。
人类不断研究，不断创新纪录。
发展到现在人们广泛使用的万年历。
