由于单片机具有体积小、易于产品化、面向控制、集成度高、功能强、可靠性高、价格低等特点，其在工业控制、机电一体化、智能仪表、通信等诸多领域中得到了广泛的应用。
在实时检测和自动控制的单片机应用系统中，单片机往往是作为一个核心部件来使用。
但是仅单片机方面知识是不够的,还应根据具体硬件结构，以及针对具体应用对象特点的软件结合,以作完善。

课程设计课程设计说明书题目：洗衣机定时器学生姓名：学号： 200806030125 院（系）：电气与信息工程学院专业：电子信息科学与技术指导教师：20010年12月 4日目录1、设计要求 (3)2、设计思路 (3)3、基本原理与设计框图 (4)4、电路设计 (4)4、1 芯片74ls192的逻辑功能 (4)4、2 1HZ脉冲产生电路 (5)4、3 递减计数器与时间显示 (5)4、4 洗涤时间设置电路 (8)4、5 工作状态显示电路 (8)5、总路图 (9)6、分析与改进 (10)7、小结与体会 (10)8、元器件清单 (11)参考文献 (12)正文1、设计要求洗衣机定时器设计说明：洗涤常规模式为：停机(1) 洗涤时间在20分钟内由用户自行设定。
(2) 用两位数码管显示洗涤的预置时间（以分钟为单位），对洗涤过程作计时显示，直到时间到而停机。
(3) 当定时时间达到终点时，一方面使电机停机，同时发出音响信号提醒用户注意。
2、设计思路1、对于洗衣机电机的工作顺序:“启动——>正转20s——>暂停10s——>反转20s——>暂停10s——>正转20s——>……——>时间到停止”设计一个定时器控制洗衣机的电机的运转，由其正传反转及暂停时间分析知道洗衣机运转的周期为60s，并且呈现周期循环，知道时间到停止为止。
我们可以利用计数器的功能进行60s的计数，及需要一个秒计数器，并且利用洗衣机的电机工作状态转换的时间来设置正转吗、暂停、反转。
2、如此则需要为计数器设置一个合适的脉冲，设计中的秒计数器所需的脉冲必为1HZ 脉冲，因此可以考虑555定时器，利用其构成多谐振荡器产生矩形脉冲信号。
3、对于用数码管显示洗涤时间，按倒计数方式对洗涤对洗涤过程作倒计时显示，并且洗涤时间在20分钟内可由用户任意设定，并设置启动键，在预置定时时间后，按启动键开始机器运转。
分析知道我们还需要设置一个分钟计数器，可以利用秒计数器的借位端BO端连接到分计数器的DOWN端作为分计数器的输入信号来实现秒从分计数器上的借位从而构成分计数器的工作脉冲。

7.设计正确，布局合理，排线整齐，功能齐全。
二．设计原理电子计时器是一个对标准频率进行计数的计数电路。
由于计数的起始时间与所需要的起点可能会不相同，所以需要在电路上加一个校分电路，以便将分时刻跳到想要的时刻。
为了使标准的1Hz时间信号准确并且稳定，实验中我们使用了石英晶体振荡器构成脉冲发生电路。
为了使电路更加简单，实验中我们使用了两片CD4518对计时器的秒、分位进行计数，由于所使用的计数器都有异步清零端，故可通过简单的电路就可以使电路具有随时清零功能。
三．分部电路图及原理1：脉冲发生电路脉冲发生电路是构成数字式计时器的核心，他保证了时钟走时的准确及稳定。
需要产生1Hz、2HZ、500HZ、1000HZ的脉冲信号。
其中1HZ 频率用于计时器电路，2HZ频率用于校分、清零电路，500HZ和1KHZ用于整点报时电路。
为此，需将对振荡器的输出信号进行分频，这里采用NE555集成电路和分频器CD4040构成。
555定时器不仅体积小，而且用它来构成多谐振荡器，波形稳定，上升沿和下降沿小，振幅大，占空比可调，因此越来越广泛地被用作振荡器。
而后通过CD4040产生几种频率供后面使用。
2：计时电路计时电路中的计数器，可以采用二-十进制加法计数器CD4518实现。
60秒为1分，将分和秒的个位、十位分别在七段数码显示器上显示出来，从0分0秒到59分59秒，然后重新计数。

智能融合Fabric高速定时器设计应用指南说明书
Application Note AC336January 20131© 2013 Microsemi CorporationDesigning a High-Speed Timer in SmartFusion FabricTable of ContentsIntroductionThis document explains how to implement an independent timer in SmartFusion ® customizable system-on-chip (cSoC) devices using FPGA fabric. The design example uses a timer with an advanced high-performance bus lite (AHB-Lite) interface. This has been implemented so that the timer can be run with an independent clock that is asynchronous to the microcontroller subsystem (MSS) clock. The independent clock can run at a much higher speed than the MSS clock, allowing applications in which an event must be captured that has a much higher resolution than the MSS clock. This timer can be started with a programmable FPGA I/O. The MSS can initialize the timer, load the timer value, and also start the timer. The fabric logic is used to customize the external interface. The logic that interfaces the timer with the MSS takes care of synchronization so that this timer can act as a standard slave to the MSS; running with an independent clock.Design Example OverviewThe design example shows a 24-bit timer module with an AHB-Lite interface. It acts as a slave to the MSS and can be connected to the MSS via the fabric interface controller (FIC). Figure 1 on page 2 shows how the timer can be connected to the MSS.Introduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1Design Example Overview . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1Description of the Timer Block . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2Interface and Register Description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4Hardware Implementation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6Running the Design . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7Conclusion . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8Appendix A – Design Files . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9List of Changes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9Designing a High-Speed Timer in SmartFusion Fabric2Description of the Timer BlockThe timer has a decrementing counter and its count value is loaded from the MSS. It has several registers that can be accessed through the AHB-Lite interface. The timer can be started by the MSS or the FPGA I/O. The counter uses FABTIMER_CLK, which can run at a separate frequency than the MSS clock. The maximum MSS clock frequency is 100 MH z . However, this design example allows running FABTIMER_CLK at a much higher speed than the MSS clock. Figure 2 shows the top-level block diagram of the timer. It has several unit/components: sync block, prescale, interrupt, sampling, and decrementing counter.Sync BlockThis block performs the clock synchronization. It monitors AHB-Lite bus signals and passes various register settings from the MSS clock to the FABTIMER_CLK clock. It also allows reading the register settings from the FABTIMER_CLK clock domain and passing it to the MSS clock domain. This block decodes the AHB-Lite address and depending on the HWRITE signal, performs a read or write operation. The design example assumes that the MSS clock and the FABTIMER_CLK are asynchronous to each other. It uses the handshake protocol to transfer data between these two asynchronous clock domains.Figure 1 • Fabric Timer Connected to MSS via FICFigure 2 • Fabric Timer Top-Level Block DiagramDescription of the Timer Block3A handshake protocol circuit uses less logic and guarantees that all bits of a data bus crossing an asynchronous clock domain are registered by the same clock edge in the receiving clock domain. The two domains exchange data via the reg_load_en signal, which is the request signal from HCLK to the FABTIMER_CLK domain, and the reg_load_ack signal, which is the acknowledge signal from FABTIMER_CLK to the HCLK domain. Figure 3 shows this state simplified. The basic operation sequence has the following steps:1.The HCLK domain sends a reg_load_en0 signal to the FABTIMER_CLK domain, which isregistered at FABTIMER_CLK domain, to generate reg_load_en2.2.The FABTIMER_CLK domain at this point reads the AHB_lite bus signals from the HCLK domainand updates the appropriate registers.3.After this read operation has finished, the FABTIMER_CLK domain sends a reg_load_ack0signal, which gets registered by HCLK domain, to generate reg_load_ack2.4.The HCLK domain turns off the reg_load_en0, which eventually turns off the reg_load_en2.5.Once the FABTIMER_CLK domain sees a low reg_load_en2 signal, it turns off the reg_load_ack0signal to the FABTIMER_CLK domain.6.Once the HCLK domain sees the low reg_load_ack2 signal, the data transfer between the twoasynchronous domains is complete.Figure 3 • Handshaking Protocol Between HCLK and FABTIMER_CLK DomainDesigning a High-Speed Timer in SmartFusion Fabric4PrescaleThe prescale component is used to provide a clock enable pulse for the decrementing counter. It allows dividing the counter clock (FABTIMER_CLK) by 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, or 1,024. Note that the FABTIMER_CLK can be driven for the clock condition circuit (CCC) or it can be driven by the FPGA I/O.Decrementing CounterThe decrementing counter is a 24-bit down counter. The counter can operate in two modes: Continuous mode and One-shot Timer mode. In Continuous mode, when the counter reaches zero, the counter is reloaded with the start value, which is stored in a programmable register, and continues to count down. In One-shot Timer mode, the counter decrements from its high value and halts on reaching zero. The timer must be reprogrammed from the MSS to begin counting down again.InterruptThe interrupt unit handles the interrupt generation. Two output ports, TIMINT and TIMINT_pending, show two types of interrupts. TIMINT is generated every time the counter reaches zero. TIMINT_pending holds the interrupt and is only cleared when the interrupt clears the register to which TIMERINTCLRA is written. Since the counter is running in the FABTIMER_CLK domain, this block stretches the interrupt pulse so it can be captured by HCLK and also synchronizes the interrupt signals with HCLK. SamplingThe sampling block samples Pulse_in input and detects the rise and fall condition. The counter starts when Pulse_in has a falling edge.Interface and Register DescriptionTable1 gives the port descriptions for the design example.Table 1 • Interface DescriptionSignal Direction DescriptionHCLK Input AHB bus clock. This clock times all bus transfers.HRESETn InputReset.Thebus reset signal is active Low and is used to reset the system and the bus.This is the only active Low AHB signal.HADDR[4:0] InputAHBaddress.HWRITE Input Transfer direction. When High, this signal indicates a write transfer and when Low, aread transfer.HSIZE[2:0] InputTransfersize.Indicates the size of the transfer, which can be byte (8-bit), half-word(16-bit), or word (32-bit). 000 – Byte, 001 – Half-word, and 010 – Word. Only word sizetransfer is used in the design example.HWDATA[31:0] Input 32-bit data from the masterHREADY Input Ready signal from all other AHB slaves.HSEL Input Combinatorial decode of HADDR, which indicates that this slave is currently selected. HRDATA[31:0] Output 32-bit data written back to the master.HREADYOUT Output Transfer done. When High, the HREADY signal indicates that a transfer has finishedon the bus. This signal can be driven Low to extend a transfer.Interface and Register Description5Several registers are available to dynamically control the operation of the timer. Table 2 shows the register settings.HRESP[1:0] Output Transfer response, which has the following meanings:00 = Okay 01 = Error 10 = Retry 11 = Split HTRANS[1:0]InputTypes of transfer: 00 = Idle 01 = Busy10 = Non-sequential 11 = SequentialTIMINTOutput Interrupt output for timer.

If your computer does not have the HyperTerminal program, use any free serial terminal emulation program such as PuTTY or Tera Term. Refer to the Configuring Serial Terminal Emulation Programs tutorial for configuring the HyperTerminal, Tera Term, and PuTTY .When you run the debugger in SoftConsole, the PuTTy window provides the user interface to select Timer mode. Figure 6 shows the screenshot of the PuTTy.Release modeThe release mode programming file (STAPL) is also provided. Refer to the Readme.txt file included in the programming zip file for more information.Refer to Building Executable Image in Release Mode and Loading into eNVM tutorial for more information on building an application in release mode.ConclusionSmartFusion cSoC FPGA devices have a programmable high-performance analog block, FPGA fabric,and a hardened ARM ® Cortex ™-M3 processor microcontroller block. The microcontroller block is composed of a 100 MHz Cortex-M3 processor and standard microcontroller peripherals, including two timers. Similar to a standard microcontroller, these timers are clocked with the PCLK0 that is generated from a microcontroller clock, also called MSS clock. This maximum PCLK0 frequency is 100 MHz.Figure 6 • PuTTy WindowAppendix A – Design Files9However, the FPGA fabric allows creating a custom timer with an independent clock that can be asynchronous to the MSS clock. This clock can run at a much higher speed than the MSS clock and help applications, where an event with higher resolution than the MSS clock is needed, to be captured. This application note shows the design example for that timer.Appendix A – Design FilesYou can download the design files from the Microsemi SoC Products Group website:/soc/download/rsc/?f=A2F_AC336_DF.

They operate over an universal range of supplyvoltages and a large time delay range, within compact dimensions. The easy-to-set front-face potentiometers, with direct reading scales, provide accurate time delay adjustment.Operating modeThe CT-APS.12 with 1 c/o contact offers 10 time ranges, from 0.05 s to 300 h, for the adjustment of the time delay. The time delay range is rotary switch selectable. The fine adjustment of the time delay is made via an internal potentiometer, with a direct reading scale, on the front of the unit.Timing is displayed by a flashing green LED labelled U/T.2C D C 251 037 V 0011Function diagramOFF-delay with auxiliary voltageThis function requires continuous control supply voltage for timing.If control input A1-Y1/B1 is closed, the output relay energizes immediately. If control input A1-Y1/B1 is opened, the time delay starts. The green LED flashes during timing. When the selected time delay is complete, the output relay de-energizes and the flashing green LED turns steady.If control input A1-Y1/B1 recloses before the time delay is complete, the time delay is reset and the output relay does not change state. Timing starts again when control input A1-Y1/B1 re-opens.If control supply voltage is interrupted, the output relay de-energizes and the time delay is reset.Electrical connectionWiring instructionsControl input (voltage-related triggering)The control input Y1/B1 is triggered with electric potential against A2. It is possible to use the control supply voltage from terminal A1 or any other voltage within the rated control supply voltage range.4 - Electronic timer CT-APS.12 | Data sheetTechnical DataData at T a = 25 °C and rated values, unless otherwise indicatedInput circuitsSupply circuit A1‑A2Rated control supply voltage U S24-48 V DC, 24-240 V ACRated control supply voltage U S tolerance24-48 V DC-15...+10 %24-240 V AC-15...+10 %Rated frequency DC n/aAC50/60 HzFrequency range AC47-63 HzTypical current / power consumption24 V DC230 V AC115 V AC24-48 V DC12 mA /on request- / -- / -24-240 V AC- / -50 mA /on request33 mA / on requestPower failure buffering time24 V DC min. 15 ms230 V AC min. 20 msControl circuitControl input, control function A1-Y1/B1start timing externalKind of triggering voltage-related triggeringRestistance to reverse polarity yesPolarized noCapable for switching a parallel load yesMaximum cable length to the control inputs50 m - 100 pF/mMinimum control pulse length20 msControl voltage potential see rated control supply voltage U SCurrent consumption of the control input24 V DC 1.2 mA230 V AC8 mATiming circuitKind of timer Single-function timer OFF-delay with auxiliary voltageTime ranges 0.05 s - 300 h0.05-1 s, 0.15-3 s, 0.5-10 s, 1.5-30 s, 5-100 s,15-300 s, 1.5-30 min, 15-300 min, 1.5-30 h, 15-300 h Recovery time< 80 msRepeat accuracy (constant parameters)Δt <± 0.2 %Accuracy within the rated control supply voltage toleranceΔt < 0.004 %/VAccuracy within the temperature rangeΔt < 0.03 %/°CUser interfaceIndication of operational statesControl supply voltage / timing U/T: green LED V: control supply voltage appliedU/T: green LED W: timingRelay status R: yellow LED V: output relay energizedData sheet| Electronic timer CT-APS.12 - 5Output circuitsKind of output15-16/18Relay, 1 c/o (SPDT) contact Contact material Cd-freeRated operational voltage U e250 VMinimum switching voltage / Minimum switching current12 V / 10 mAMaximum switching voltage / Minimum switching current see ‘Load limit curves’ on page 8 Rated operational current I e (IEC/EN 60947-5-1)AC12 (resistive) at 230 V 4 AAC15 (inductive) at 230 V 3 ADC12 (resistive) at 24 V 4 ADC13 (inductive) at 24 V 2 AAC rating (UL 508)utilization category (ControlCircuit Rating Code)B 300max. rated operational voltage300 V ACmax. continuous thermalcurrent at B 3005 Amax. making / breakingapparent power at B 3003600/360 VAMechanical lifetime30 x 106 switching cycles Electrical lifetime AC12, 230 V, 4 A0.1 x 106 switching cyclesMaximum fuse rating to achieve short-circuit protection (IEC/EN 60947-5-1)n/c contact 6 A fast-acting n/o contact10 A fast-actingGeneral dataElectrical connection6 - Electronic timer CT-APS.12 | Data sheetEnvironmental dataAmbient temperature ranges operation-25...+60 °Cstorage-40...+85 °CDamp heat, cyclic (IEC/EN 60068-2-30) 6 x 24 h cycle, 55 °C, 95 % RH Vibration, sinusoidal (IEC/EN 60068-2-6)functioning40 m/s2, 10-58/60-150 Hzresistance60 m/s2, 10-58/60-150 Hz, 20 cycles Vibration, seismic (IEC/EN 60068-3-3)functioning20 m/s²Shock, half-sine (IEC/EN 60068-2-27)functioning100 m/s2, 11 ms, 3 shocks/directionresistance300 m/s2, 11 ms, 3 shocks/direction Isolation dataRated insulation voltage U i input circuit / output circuit500 VRated impulse withstand voltage U imp between allisolated circuits (IEC/EN 60664-1, VDE 0110)4 kV;

它全面支持WINDOWS 9X/ME/NT/2K/XP按时执行程序、播放声音、关机、待机、拨号、断开连接、关闭显示器等等操作。
具有多种设定任务的方法。
支持SKIN，可以随意更换界面。
人类最早使用的定时工具是沙漏或水漏，但在钟表诞生发展成熟之后，人们开始尝试使用这种全新的计时工具来改进定时器，达到准确控制时间的目的。
1876年，英国外科医生索加取得一项定时装置的专利，用来控制煤气街灯的开关。
它利用机械钟带动开关来控制煤气阀们。
起初每周上一次发条，1918年使用电钟计时后，就不用上发条了。
定时器确实是一项了不起的发明，使相当多需要人控制时间的工作变得简单了许多。
人们甚至将定时器用在了军事方面，制成了定时炸弹，定时雷管。
现在的不少家用电器都安装了定时器来控制开关或工作时间定时器的种类：1、接通延时型定时器：接通延时型定时器是各种PLC中最常见最基本的定时器，这种定时器在 SIEMENS的PLC中，称为SD型定时器2、断开延时型定时器：这种定时器是当输入条件00000为ON时无延时作用，只有在输入条件00000为OFF时产生延时作用。
在SIEMENS的PLC中，称为SF型定时器3、保持型接通延时定时器：这种定时器是当输入条件00000为ON后，即产生锁存功能，即使输入条件00000又变为OFF，仍视输入条件为ON，当定时器的当前值等于设定值时，定时器动作，这种定时器在SIEMENS的PLC中，称为SS型定时器4、脉冲型定时器：这种定时器是当输入条件00000为ON后，定时器即时动作，但经过定时器所设定的时间后，即使输入条件00000仍为ON，定时器却变为OFF状态。
即这种定时器ON状态的维持时间是由设定值决定的。
如果00000为ON的时续时间小于定时器的设定值，定时器的ON状态维持时间为输入条件00000为ON的持续时间。
这种定时器在SIEMENS的PLC中，称为SP型定时器。
5、扩张型脉冲定时器：这种定时器与脉冲型定时器的区别是，只要输入条件00000出现了ON状态，不管其持续时间多长，均可使定时器为ON的维持的时间与定时器的设定值一致。
这种定时器在SIEMENS的PLC中，称为SE型定时器。
二、定时器设计要求定时器电路是一种将模拟功能与逻辑功能巧妙地结合在同一硅片上的组合集成电路。
该电路可以在最基本的典型应用方式的基础上，根据实际需要，经过参数配置和电路的重新组合，与外接少量的阻容元件就能构成不同的电路，因而555电路在波形的产生与变换、测量与控制、家用电器、电子玩具等许多领域中都得到了广泛应用。
设计一个定时器，使它每六个小时向工作单元发送一个工作脉冲。
这里所设计的定时器是在一般条件下工作的定时器。
要求是能够进行六个小时的定时。
当定时结束，蜂鸣器报警。
在实际工作中，也可根据实际需求，将蜂鸣器换成其他的元件，或者也可以外接驱动电路对实际工作元件（如电动机等）进行驱动。
具体的工作是通过一个六个小时的定时器，使一个球阀完成每六个小时开一次，每六个小时关一次的动作。
三、定时器设计步骤电源开关若没有上一级电路则发出"劈"响电子蜂鸣器为带有"劈""劈"响声间隔的电路几赫的振荡SW2SW1→→由时钟0→1→2……→9顺序分别变为、用旋转开关设置时间内部装有晶振时间设置开关产生标准时间计数器（1）计数器（2）触发器振荡电路电源接通复位图3.1定时器结构图图3.1使我们制作的定时器框图。
这个图由四部分组成：左边是一个用于产生标准时间的计时装置、中间是由计数器（1）、计数器（2）组成的计数单元、右上角是由RS触发器、振荡电路、蜂鸣器构成的动作单元，最下面是用于整个电路复位的电源接通复位单元。
图 3.2是定时器的示意时序图。
当电源接通时，复位电路首先开始工作，它使所有的数字集成电路复位。
然后，基准时间每五分钟输出一个脉冲，作为基准系统时钟。
计数器（1）以五十进制计数，即每五十分钟向计时器（2）发送一个脉冲。
计数器（2）以五百进制计数。
当条件满足（两个计数到第六个小时时），RS触发器置位开始动作，产生输出Q，振荡电路使蜂鸣器发出“劈”的声响。
整个电路完成一次六个小时的定时。
劈"设置时间百进制计数十进制计数蜂鸣器振荡电路输出复位触发器的置位计数器（2）10计数器（1）1计时装置脉冲接通电源复位接通电源图3.2定时器的示意时序图一种分别测量和累积计算用电单位计量柜各相断相时间的方法，由断相传感器和用电传感器分别从用电单位的计量柜的电压互感器和用电线路上获取断相信号和用电信号，仅当上述两种信号同时加到控制单元时才驱动相应计时器计时。
实施该方法的计时装置可有电压闭锁式和电流闭锁式两种型式，它们均由面板、机壳、断相传感器、断相信号变换器、用电传感器、用电信号变换器、控制器、电计时器等部件所组成。
两种断相计时装置可采用石英电子钟作计时器，计时精确可靠。
计时装置在这里使用准确的时间脉冲振荡器。
多谐振荡器的振荡频率不够准确。
另外，考虑到电路的可靠和简单，选择使用模块化的，做成集成电路形式的晶体振荡器。
复位电路的作用是：当电源接通时产生脉冲，使各个电路复位。
一般地，计数器触发器以及带触发器的各种集成电路，输出的电压是不确定的。
而现在的工作条件下，要求在电路开始工作时，必须知道触发器初始状态是怎么样的。
所以，必须设置复位电路，在接通电源后，通过复位电路，对各计数器触发器置零为确保微机系统中电路稳定可靠工作，复位电路是必不可少的一部分，复位电路的第一功能是上电复位。
一般微机电路正常工作需要供电电源为5V±5%，即 4.75～5.25V 。
由于微机电路是时序数字电路，它需要稳定的时钟信号，因此在电源上电时，只有当VCC 超过4.75V 低于5.25V 以及晶体振荡器稳定工作时，复位信号才被撤除，微机电路开始正常工作。
两个计数单元分别由一个十进制计数器构成，由它对标准时间脉冲进行计数。
该十进制计数器的个位输出端根据计数基准脉冲个数，顺序输出高电位，当个位输出端输出脉冲位置当从9变到0时，则产生一个负电位的十进制脉冲。
第二个计数器对这个负电位的脉冲进行计数，从而在结构上完成进位。
通过计算，我们将标准时间脉冲设置位于分钟时，计数器（1）是五分位，计数器（2）是五十分位。
当六个小时计时结束时，通过动作装置完成对球阀的驱动。
因此，首先需要一个逻辑电路，用它来判断六个小时计时结束。
定时器的开关（1）接在计数器（1）的第十个脉冲输出端口，用于设定个位的0～9分；定时器的开关（2）接在计数器（2）的第三个脉冲输出端口，用于设定十位。
个位和十位设定的时间输出都是高电位。
当“与非”门取出时间设定与计数值一致的信号时，即完成了判断。
RS触发器被置位。
RS触发器的输出Q控制振荡电路，使电子蜂鸣器发出“劈……劈”的断续报时声响。
如果用于球阀的驱动，则可以将电子蜂鸣器换成放大电路，外接一个电动机来驱动球阀。
四、定时器电路设计图4.1定时器电路图4.1是实际的定时器整体电路图。
电源为三节1.5V 电池。
十进制计数器使用CMOS4000B 系列中的4017B 集成电路。
此外，驱动电子蜂鸣器的集成电路也消耗电能，这里使用大电流高速CMOS74HC 系列，其耗用电流可达20mA。
4000B 系列CMOS 的耗用电流为10mA。
电子蜂鸣器是内部装有振荡电路的蜂鸣器，与别的电路相组合，可以发出断续音。
4.1 计时装置定时器的基准时间，和数字表等一样使用频率稳定度非常好的晶体振荡器。
由于晶体振荡器的振频率在数十KHz 以上，有必要使用分频器来分频，使其频率下降。
基准时间发生集成电路使用的是可编程晶体振荡器 SPG8651B 芯片。
晶体振荡器和用程序可任意设定的分频器组装在一个芯片中。
1：H0：OPEN以上是8651B 控制端设定表。
CTL1~CTL6按表中给出的那样设定，能够输出100KHz ～1/1200Hz 的频率，上表中1表示接高电平，0表示接地。
根据现在的设计任务，我们选定输出频率为1/300，即CTL1接地，其余接高电平，时钟每5分钟输出一个脉冲。
4.2 复位电路电源接通电源接通时DD图4.2复位电路 (1)图3.2是电源接通后产生复位脉冲的电路。
当电源开关接通后，在电容C 和电阻R的串联电路中有充电电流流过。
在电阻R两端产生了如图中①那样的电压。
当充电结束后充电电流没有了，电压变为零。
电源接通后，在②处产生负脉冲，③处产生正脉冲，将该脉冲加给计数器和触发器的复位端，使之初始化。
图 3.3是电源断开时的电路图。
在电源关断时，电容C上保持的电荷通过二极管向电源放电。
放电时的电流不通过电阻R，时间常数变小，放电时间很短。
复位电路恢复到初始工作状态。
图4.3复位电路 (2)4.3 计数电路计数电路中使用的十进制计数器是CMOS4000B 系列中的4017B 集成电路。
该计数器和普通的十进制计数器BCD计数器有所不同。
它在约翰逊计数器中装入了十进制译码器，所以对这里的使用是非常重要的集成电路。
该集成电路的时序图如图3.4。
时钟使能端为L，clock端加上脉冲，则用时钟的上升沿来计数。
这是一种非常有益的功能。
在定时电路设计中，计数器（1）的4017B作为基准时钟SPG8651B的输出，每五分时钟的下降沿来计数。
输出端Q0～Q9依次输出H。
另外，计数器（1）的cappy out，即进位输出端每10个时钟向计数器（2）输出一次，也就是每五十分钟升起一次，完成五十分钟的计数。
计数器（2）将这个信号的升起次数进行计数。
