摘要
本文设计了一种基于CC2500无线收发模块的无线抢答器。该抢答器主要由无线模块、控制模块、USB通信模块等组成,此系统工作于免费的2.4-2.485GHz免许可证ISM频段,抗干扰能力强、减少现场布线麻烦。实现了抢答、评分、记分、计时以及屏幕显示、分数统计、信号监控等功能。通过USB通信,实现PC监控,具有高拓展性。可满足不同竞答赛事的不同需求,特别适用于高制作要求的电视直播竞答活动,能提高活动档次,简化工作流程,减少人为失误、节约竞赛成本。
a Wireless Responder device was designed,which is based on CC2500.It mainly by the wireless module,control module,USB communication modules and other components,this system work in the free 2.4-2.485GHz unlicensed ISM band,interference resistance,reduce field wiring trouble.To achieve the answer in,score,scoring,timing,and the screen display,fractional statistics,signal monitoring.Communication via USB,a PC monitor with high scalability.A different race events to meet the different needs,particularly for high production requirements of the activities of live television quizzes,activities can improve grades,and streamline workflow,reduce human error,saving the cost of competition.
