摘　　要：随着人们业余生活的丰富,抢答器的作用越来越重要。该文介绍了一种八路抢答器的设计。该设计是以单片机为基本核心,在完成按键、显示、报警等硬件电路设计之后,配备相应的应用软件,然后设计制作硬件电路。经过测试,该系统达到了预期目标,实现了抢答、倒计时、违规显示、报警、双面显示等功能。该系统可应用于小型知识竞赛以及文娱活动等场所,具有一定的应用价值。Sparetime life of people are plentiful, the use of responder is more and more important. We introduced a kind of eight-way responder in this paper. It put single chip as basic core,we complete the design of hardware circuit,such as key,display,alarm and so on, we also complete software design. The test show that the system has reached the expected goal,achieve the following functions, such as preemptive answer,count down,violations,display,alarm, dual display and so on.the system can apply to small knowledge competition and recreational activities, it has certain application value.
