摘要
傳統的搶答器都是導線布線，受現場環境影響很大。本文介紹的六路無線搶答器，是以8051單片機為核心制成的，其功能為連續可調的0到9秒的，搶答有效有高頻鈴聲并顯示組別，搶答無效有低頻鈴聲也是顯示組別，并且有計分功能，預置100分，答對為加10分，答錯為減10分，由主持人手動復位，加減分，所以此搶答操作方便，在很多的場所都可以使用，并且給人的視覺效果非常好。
關鍵字：搶答器、智能搶答器、無線編解碼、單片機。

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.
