| 中文摘要: |
| 目前市场上的智力竞赛抢答器已经相当成熟，但由很多电路组成，线路复杂，可靠性不高，功能也比较简单，特别是抢答器路数很多时，实现起来比较困难。因此设计以单片机为核心的新型智能抢答器，利用AT89S52单片机及外围接口实现抢答系统，结合单片机的定时器/计数器的功能，将软、硬件有机地结合起来，使得系统能够正确地进行计时，使数码管能够正确地显示时间。所设计的系统具有反应快、操作简单、实用性强的特点。 |
| 英文摘要: |
| The rush-answer system for quiz has been quite mature in the market at present, but it is composed of many complex circuits, the reliability is not stable and the function is simpler. It is more difficult to implement when the system involves multichannel. So we designed a new intelligent rush-answer system based on single-chip microcomputer, which uses AT89S52 single-chip microcomputer and peripheral interface. This system combined the software and hardware organically with single-chip microcomputer timer/counter, which enables the system to time accurately and the digital tube to display the time correctly, at the same time, it has many characteristics like quick reaction, simple operation, and strong practicability. |
