摘要:
近年来随着工业和科技的飞速发展，单片机的应用正在不断地走向深入，同时带动传统控制检测日新月异更新。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，加以完善。
本设计组要分两个部分：硬件部分的设计和软件部分的设计。在硬件部分将介绍抢答器的工作状态和抢答器的硬件手工图。在软件设计部分将介绍：1,抢答器的时续控制电路2,抢答器的报警电路，3,抢答器定时电路，4,抢答器抢答电路，5,抢答器数码管点亮电路，6,抢答器的总程序。
本设计的特点是电路结构简单、程序简短、系统可靠性高，能够实现课题中所提的设计要求。

Abstract:
In recent years along with industry and technical swift development.Monolithic integrated circuit's application is moving toward thoroughly unceasingly .simultaneously leads the traditional control examination to change with each new day the renewal.In real-time examination and in automatic control monolithic integrated circuit application system ,The monolithic integrated circuit often is takes a core part to use,But only the monolithic integrated circuit aspect knowledge is insufficient ,We should also act according to the concrete hardware architecture,And in view of concrete application object characteristic software union ,Consummates .
This design team must divide two parts ,Hardware part design and software part design.In the hardware part will introduce vies to answer the first active status and vies to answer first hardware manual chart ,Will introduce in the software design part :1st, vies to answer first when continues the control circuit .2nd, vies to answer first alarm circuit, 3rd, vies to answer the first timing circuit, 4th, vies to answer first vies to answer the first electric circuit, 5, vie to answer the first nixietube to lighten the electric circuit,6th, vies to answer first total procedure.
This design's characteristic is the circuit structure is simple, the procedure brief, the system reliability is high, can realize the design requirements which in the topic raises.
Key words:
Monolithic integrated circuit (MIC),Vies to answer first ,Electric circuit ,Procedure .777
