摘要
根据建设国家防汛抗旱指挥系统的技术要求,结合近几年来系统实施和运用,遥测站配备数据在站存贮及远程批量传输技术可行。描述水文遥测终端RTU内集成SPI串行固态存贮电路的技术设计思路,给出设计案例。现地存贮的数据由GPRS传输通道进行远程提取。
According to technological requirements of the state flood control and drought resistance commanding system, and combined with system operation of several years, it has proved that telemetric data storage at stations and remote batch transmission technology is feasible. In this article, design idea for integrated SPI serial solid storage circuit in the remote terminal unit are described, and it＇s design case is also given out. Field stored data are picked up by GPRS transmission channel.
