摘要
根据明渠流速流量测量技术规范和远距离数据传输的需求,以旋浆式流速仪为一次测量仪器,设计了基于GPRS的明渠流速流量检测系统。系统采用固态存储技术,实现数据在下位机中的大量存储。通过采集电路及GPRS终端,利用通用分组无线业务(GPRS)和Internet网实现远程数据的采集与控制,解决了水文水生态监测中分散数据传输问题,实现了水文信息实时采集传输和处理的无线化、网络化、智能化。
According to the standard of open channel speed and flow quantity t and the long-distance requirement of the dates transmitting, the open channel speed and flow quantity measurement system of water based on GPRS was designed, which used propeller＇s current meter as first measuring instrument.The system used the technology of solid state storage to realize the massive date＇s storage. Through the gathering circuit and GPRS terminal, using technology of GPRS and Internet network, we realized the data gathering and controlling in long distance, soluted the question of transmission in dispersion data. Finally this sys- tem realized wireless, network and intellectualization of the real-time gathering, transmitting and processing of water information.
