摘要
GPRS现场仪表远程监控系统由数据中心和位于现场的仪表数据采集点组成,现场仪表数据通过中国移动现有的GPRS/GSM网络进行传输。现场仪表通过RS232口或485口与GPRS透明数据传输终端连接现场仪表数据经过协议封装后发送到中国移动的GPRS数据网络,通过GPRS数据网络将数据传送至数据中心,实现现场仪表数据和数据中心系统的实时在线连接,从而实现监控。
The GPRS scene measuring appliance long-distance supervisory system is composed of the data center and the instrumented data gathering spot. The transmission of scene instrumented data is carried through China mobile GPRS/GSM network .The scene measuring appliance is connected to the scene instrumented data through the RS232 interface or 485 with the GPRS transparent data transmission terminal to transmit the GPRS data to network after the protocal packaging which moves to the data center through the GPRS data network, realizes the scene instrumented data and the data center system real-time on-line connection, thus realizes monitoring.
