本系统以AT89S52单片机为核心部件，外加温度采集电路、及显示电路和越限报警等电路。采用单总线型数字式的温度传感器DS18B20，使系统具有测温误差小、分辨率高、抗干扰能力强，动态显示的方式等特点。本设计既可以对当前温度进行检测又可以对温度进行数码显示，两位整数两位小数的显示方式具有更高的显示精度，若超越极限温度则触发蜂鸣器报警。利用功能强大的Keil和具有互动电路仿真的Proteus进行程序的编写和仿真。-The system AT89S52 microcontroller as its core components, plus the temperature acquisition circuit, and display circuitry, and the more limited alarm circuits. Single bus-type digital temperature sensor DS18B20, the system has a temperature measurement error of the small, high resolution, anti-interference ability, dynamic show the way and so on. This design not only can detect the current temperature can also right temperature digital display, two integers with two decimal places are displayed to show a higher precision, if the temperature is beyond the limits of buzzer alarm is triggered. Keil and the use of powerful interactive circuit simulation of the Proteus programming the preparation and simulation.

（1） 有一个主持人控制开关和8路抢答按扭，当主持人允许抢答时才能进行抢答操作，并用一个数码管显示抢答选手的号码，同时其他选手不能再抢答。
（2）电路上要加个蜂鸣器的电路，当有选手抢答时蜂鸣器响一下。
（3）要有倒计时功能，开始抢答时开始倒20秒计时，用两个数码管显示，当有人抢答时停止倒计时。
2.2拓展部分
用按键可设置倒计时的时间，范围在5秒到30秒之间。-(1) has a host switch and 8-way control button to answer in, when the moderator allowed to be carried out to answer in time to answer in operation, and use an LED display to answer in the number of players, while other players can no longer answer in his place. (2) the circuit, we should add a buzzer circuit, when there are players when the buzzer rang to answer in about. (3) to have the countdown feature to begin to answer in 20 seconds when you start down time, using two digital tube display, when someone stops to answer in the countdown. 2.2 The expansion of part of the buttons can be set with the countdown time, the range of 5 seconds to 30 seconds.
