偏远地区地下水监测系统通信组网方法

Communication network method of groundwater monitoring system in remote areas

针对偏远地区地下水监测中存在的数据传输稳定性低、GPRS通讯网络存在覆盖盲区等问题,研究利用北斗卫星通信短报文点对点数据传输、覆盖范围广、高效便捷等特点,将GPRS、北斗卫星通信组网应用于偏远地区地下水监测。结合西藏野外环境特点,对西藏自治区地下水水位以及温湿度数据进行监测,监测的水文数据传回中心站,对数据进行处理、分析与展示等。结果表明,GPRS+北斗卫星通信的双信道一体化地下水监测系统,能够解决公共通信网络覆盖盲区以及应急监测信号不稳定等问题,提高数据畅通率,为偏远水文高质量建设与运行管理提供技术支撑。

In view of the problems of low data transmission stability and blind coverage of GPRS communication network in groundwater monitoring in remote areas,this paper applies GPRS and Beidou satellite communication network for groundwater monitoring in remote areas by utilizing the characteristics of point-to-point data transmission,wide coverage,high efficiency and convenience of Beidou satellite communication short message.Combined with the characteristics of field environment in Tibet,groundwater level,temperature and humidity data in Tibet Autonomous Region are monitored and sent back to the central station for processing,analysis and display.Results show that the dual-channel integrated groundwater monitoring system including GPRS and Beidou satellite communication can solve the problems of blind coverage area of public communication network and unstable emergency monitoring signal,improve the data unimpeded rate,and provide technical support for the high-quality construction and operation management of hydrology in remote area.
