自行车电子里程表的初步设计

A Design of Bicycle Odometer

设计分为四个模块:数据采集、数据处理、电源模块和键盘与显示模块。数据信号采集采用高灵敏度光电管,并对被测信号进行4倍频放大;数据处理以单片机AT89C52为核心,对采集信号进行精确和严格计算;电源模块为自行设计制作的高效、低功耗充电模块;显示部分由OCMJ-B型液晶构成。

This design is composed of 4 modules:data collecting module, data processing module,power module,and keyboard and display module.And the first module which employs highly sensitive ptotoelectric tube,can amply the collected signals by 4 times.The second module,based on single chip AT89C52,can accurately calculate the collected signals.The third is highly efficient and power-consuming rechargeable module, designed for bicycle.The Last is composed of OCMJ-B type liquid crystal.
