摘要
为了解决土壤墒情监测数据通信能力差的问题,设计了一种基于北斗卫星与GPRS的土壤墒情监测系统。利用基于TDR的土壤水分传感器采集墒情数据,并以规定报文格式通过北斗卫星与GPRS传输至控制中心,北斗卫星为主信道,GPRS为备信道,实现主、备信道自动切换功能,进行多信道多协议土壤墒情监测传输、显示、查询,为抗旱减灾提供技术支撑。
In order to solve the problem of poor communication ability of soil moisture monitoring data,a soil moisture monitoring system based on Beidou satellite and GPRS was designed.The TDR based soil moisture sensor was used to collect soil moisture data and transmit it to the control center through Beidou satellite and GPRS in the specified message format.Beidou satellite was the main channel and GPRS was the backup channel.The function of automatic switching between the main channel and the backup channel was realized.The multi-channel and multi protocol soil moisture monitoring transmission,display and query were carried out,which provided technical support for drought resistance and disaster reduction and has good promotion prospects.
