一种人性化抢答系统的设计

设计一套灵活性和实用性更强的人性化抢答系统,以满足一般小规模抢答比赛的相关需求.方法:基于AT89C51单片机并配合ISD1420语音芯片和YM12232B型液晶的使用,围绕系统的3大基本功能--抢答﹑语音提示和液晶显示,将电路设计分成3个相应部分同时采用模块化软件设计.结果:经10次以上的认真调试系统已排除了各种故障,可对抢答全程进行语音提示和液晶显示,实现了人性化的使用效果.结论:系统完全能够胜任一般小规模抢答比赛的任务,而比赛网络远程化的趋势则必将是新的期待和挑战.

Design of Human Answer Bell System

To design a kind of human answer bell system with more flexibility and practicality to meet the requirements of a small-scale talent contest.The design in hardware was broken down into three relevant segments on the basis of functions of answer,speech suggest and LCM display with the use of an AT89C51 microchip,a YM12232B model LCM and a speech chip ISD1420.The software implementation was done by modular programming.Through over ten earnest tests the system excludes sorts of malfunction and is able to give speech suggest and LCM display during the contest so as to attain the human use effect.The system serves the purpose of accomplishing a small-scale talent contest and to design a better answer bell system will is a new challenge and a kind of expectation with the tendency of distance contests on the net.
