Abstract
The tradition vies to answer first is the wire wiring, is been very big the scene environmental effect. This article introduced six groups vie to answer first wireless, is makes take 8051 monolithic integrated circuits as the core, its function for continuously adjustable 0 to 9 seconds, vies to answer first has the high frequency ting effectively and demonstrates the category, vies to answer first invalid has the low frequency ting also demonstrates the category, and has the scoring function, initializes 100 points, responds to add 10 points, answers wrong to reduce 10 points, by the director hand reset, adds and subtracts the minute, therefore this vies to answer the first ease of operation, may use in many places, and gives person's visual effect to be good.
key words Vies to answer first, the intelligence to vie to answer first, arranges the decoding, the monolithic integrated circuit wireless.
