介绍了一种基于加速度传感器ADXL105和无线数传模块的运动员起跑反应时测量系统的设计和实现。该系统通过以89C2051为核心的前端反应时测量装置实时采集运动员的反应时,然后通过无线数传模块将运动员反应时传送到PC机进行显示,并对该反应时进行记录处理,绘制成运动员反应时曲线图。
An accelerometer ADXL105 and wireless data transmission module based on the athlete starting reaction time measurement system design and implementation. The system through 89C2051 as the core of the front-end reaction time measuring device real-time acquisition of athletes reaction, and then through wireless data transmission module athletes reaction will be sent to the PC to display, and the reaction time record processing, drawn as athletes reaction When the graph.
