GPRS远程通信在远程地温监测系统中的应用

Application of GPRS communication in remote terra temperature

青藏铁路沿线环境恶劣,为开展对多年冻土区监测,并对获取的基本数据、资料建立数据库,进行系统的分析,需要建立将地温数据自动测量、上报和分析的监测系统。GSM-R网络覆盖青藏铁路沿线,远程地温监控系统在GSM-R网络中采用ARM7MCU作控制单元,控制GPRS通信模块向监控中心数据传输,监测中心可进行数据分析实现对铁路沿线路基温度监控。终端按配置时间定时测量、保存数据,并在通过GPRS方式上报测量数据。系统试运行结果表明,监控终端和中心可正常建立GPRS连接并正确上报测量数据,同时系统具有低功耗的特点。

Environment along the railway of Qinghai ＆ Tibet is extremely adverse. To implement the surveillance of tundra, establish database for gained data and information and analyze systemically, it＇s necessary to design a remote monitor system with function of measuring, communicating and analyzing automatically. GSM-R network has covered the Qinghai ＆ Tibet Railway, and the remote monitor system applies ARM7 microprocessor as its CPU processing unit. By analyzing the transmitted data sent from GPRS communication model to monitor center, terra temperature of roadbed along the railway can be monitored. The terminal system performs measurement on timing, storage data and report data through GPRS in accordance of configured time. Result of testing shows terminal can reliably establish GPRS communication with center and report data steadily, and also with low power consumption.
