在竞赛、文体娱乐活动（抢答活动）中，抢答器能准确、公正、直观地判断出抢答者，具有很广泛的应用，因此设计抢答器很有必要。本项目主要阐述了以AT89S52单片机作为核心器件，采用模块化布局，设计的一个抢答器，通过数码管显示指示出第一抢答者。本项目利用单片机的内部定时器溢出产生中断来实现定时。采用汇编和C语言进行软件编程，用keil软件进行调试，proteus软件进行仿真。最后把调试成功后的程序烧写到AT89S52单片机中，通电运行。抢答器正常工作时能指示出第一抢答者，并对违规操作进行报警。本项目设计的抢答器能很好的完成设
计任务，但本人认为这个设计并不具备推广应用价值，因为这个设计的硬件电路花费比较大，设计的项目性价比不是很高，不是很适合推广。

At the competition, stylistic entertainment activities (scare-answering activities), vies
to answer first device can accurately, justice and intuitive to diagnose vies, who has a wide range of applications, therefore design contest is very be necessary. The project
mainly elaborated by AT89S52 SCM as the core device, modular layout, the design of a vies to
implement, through digital pipe display indicates that the first vies. The project of the microcontroller timer interrupt internal to achieve timing overflow produce. Using assembly and C language keil software with software programming, debugging, proteus software simulation. Finally the debugging after the success of the program burn wrote AT89S52 SCM, electrify operation. Vies to implement during normal working can indicate the first vies victim, and to violate compasses operation for alarm. This project
design contest device can be a very good completed the design task,
But I think that this design does not possess popularization value, because this design of hardware circuit cost is larger, design project price is not very high, is not very suitable for promotion.
Key words: Scare-answering manometers; MCU; Digital tube display; alarm
