摘　　要：为构建信息化的墒情监测网络,设计了一种基于串口无线模块、GPRS和短信3种通信模式的远程墒情监测系统,该系统采用图形化的方式实现对多种数据传输方式的墒情自动监测站的数据监测。为了满足多种墒情监测环境下系统的可靠性,采用Modbus RTU方式实时读取监测数据,采用短信方式和网络通信方式定时读取监测数据。通过对土壤墒情和气象的实时数据监测及历史数据查询的图表显示实现对监测站的管理。测试运行结果表明,该系统能提高墒情监测的稳定性和可靠性。In order to establish the information-based soil moisture monitoring network, the paper designs a remote soil moisture monitoring system based on three communication modes,including serial port wireless module, GPRS and SMS, which uses graphical means to achieve data monitoring of soil moisture automatic monitoring stations in a variety of data transmission methods. In order to meet the reliability of monitoring system in various soil moisture monitoring environment, the Modbus RTU protocol is used to read the monitoring data in real-time, the text messages and network communication are used to read the monitoring timing data. Through monitoring soil moisture and meteorological data in real-time and chart display of historical data query, the management of the station is realized. The test running results show that the system can enhance the stability and reliability of soil moisture monitoring.
