Description: 本文介绍了四路智力抢答器的分模块设计电路及各模块的逻辑功能及其电路和波形展示。所设计的抢答器除了基本的锁存和复位功能外，还有其它功能：席位灯亮且扬声器响提示抢答成功；数码显示选手号码和两个倒计时（抢答和回答）；倒计时可设定（根据需要对计数器置数）；抢答倒计时可暂停，对同一道题可多次抢答直至计时归零时响警报；回答倒计时有5秒倒计时警报等。这些功能都使得该器件更加贴近现实，更加智能化、人性化-In this paper, it introduces that 4-wire answering device circuit designed by module, and the logical function of them with the display of the circuit and waveform. The device is no more than the lock and reset function: the seat light and the speaker clued on reply successful displaying of the player number and the count down timer the timer can be set up by design the reply count down timer can be paused, for that one question could be replied more than once until the timer run to zero and speaker work there are 5 seconds alarming during answering etc. All these functions would make the device close to praxis, more brainpower and more humanistic.

Description: A simple count-down LED timer that counts in minutes and seconds. Three buttons below the LED provide control of the unit, allowing you set the desired countdown time in minutes and seconds and a start/stop button.
Completion of the countdown is indicated by an alarm that starts when the countdown has finished and the display reads zero.
The alarm is stopped by pressing the start/stop button. Platform: |

Description: 电子钟的设计电子钟需要一个时钟基准信号，产生基本的而且准确的计时单位，根据实验室的实际环境，我们可以设计一个变量来计算时钟基准信号的个数，来达到计时的目的。例如用计时器计1S，计数到60时可以产生1min的定时。然后计数器清零，分加1。循环反复计数。由此实现电子钟的设计。
对于能够调节分、秒值的电子钟，当触发某一按键时，通过执行相应的程序而去对分、秒值进行加减。
所以在这里把问题归结找到计时的基本单位，并编写对应按键的程序。
-The design of electronic clock electronic clock requires a clock reference signal to produce a basic and accurate timing units, according to the laboratory' s physical environment, we can design a variable to calculate the number of clock reference signal, to achieve timing purposes. For example, the timer count with 1S, count to 60 can produce 1min timing. Then the counter is cleared, points plus 1. Cycle repeated counts. Thus to achieve electronic clock design. Able to adjust for the minute and second values of electronic clock, when the trigger of a button, through the implementation of the corresponding program away for minute and second value addition and subtraction. So the problem boils down to find where the basic unit of time, and write the corresponding button of the program. Platform: |

Description: 用方波信号发生器发出1HZ的稳定的方波信号作为CP信号输入 ,秒计数器满60向分计数器进位,分计数器满60向小时进位,小时计数器按“23翻0”规律计数，计数器经译码器送到显示器；计数出现误差可用校时电路进行校时、校分、校秒。并具有可整点报时与定时闹钟的功能。
本数字钟的功能列表如下：
1）基本功能：秒、分钟、小时计时、显示及校对；
2）整点报时功能：在每小时59分50秒开始500Hz频率发声提示，整点时1000Hz发声，之后声音停止；
3）定时报闹功能：可设定闹钟定点报闹，可用开关关闭；-Square wave signal generator with a 1 HZ stability of square wave signal as CP signal input, counter full 60 seconds to points counter carry and points to counter full 60 hours carry and hours counter press "23 turn 0" rule count, the counter decoder to display Count serious error when the circuit can be used when the school, the school to points, the school to seconds. And has the time and timing of the alarm clock function.
The function of the digital clock listed below:
1) the basic function: seconds, minutes, hours timer, display and proofreading
2) hourly chime function: every hour on 59 points 50 seconds began to 500 Hz frequency voice prompt, the hour 1000 Hz uttered his voice, the voice after stop
3) set times make function: to set the alarm clock fixed-point report make, can be used to switch to shut down

Description: 本系统共由抢答单元、答题单元和报警单元等三部分组成。
首次进行时，主持人设置答题时间，再按一次清零开关，报警器发出声音提示抢答开始，同时抢答锁存模块开始工作，抢答定时器开始减计数，并将时间通过译码电路显示在数码管上。当在规定的时间内，有选手抢答时，抢答锁存模块就将该选手的号码锁存，其他的选手的抢答无效，同时报警器发出警报，定时器停止工作，抢答时间和该选手的号码分别通过数码管显示出来。当规定的时间到并且没有人抢答，定时器递减到0，并通过译码器显示出00，同时报警器报警。
