【摘要】 分析了无源直读式远传水表用户用水量采集原理,设计了由无线收发模块CC1020构成的收发模块电路图,在此基础上设计了一种由AT89C51和CC1020模块构成的无线远传水表,并实现了相应的软件设计.解决了传统的机械水表无法实现远程抄读的问题.实验结果表明:采集的用户用水量能准确的传输到上一级采集点.更多还原

【Abstract】 The principle of gathering water consumption with a passive direct reading remote meter was analyzed.A wireless remote meter consisting of AT89C51 and CC1020 modules and a Receive Transmitter circuit consisting of Wireless Receive Transmitter CC1020 were designed.The problem that traditional mechanical meter can not be reading from the remote place was solved.The results indicate that gathered water consumption can be accurately transmitted to the upper gather point.更多还原
