摘要
设计了一种基于的线路供电的水情遥测终端,利用电话线直接供电调制解调器CMX868,并且通过供电接口将节余的电能供给下位机,实时采集雨量、水位等水文数据,并对采集到的数据进行固态存储和传送,实现雨水情数据的全年自动化记录。
The paper designs a kind of line-powered hydrology telemetric terminal which directly powers the CMX868 MODEM with the phone line, and provides the subordinate computer the surplus electricity by power interference. The terminal collects the data like real-time rainfall and water level, stores in solid-state and transmit them to the host computer, which realizes the record of hydrology data of the whole year.
