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.
