摘　　要：为了实时了解土壤墒情信息,为旱情预报预警及农业灌溉提供基础数据,设计了一套基于GPRS的土壤墒情远程监测系统。该系统利用太阳能供电,以STC12C5A60S2单片机作为主控单元核心控制器,通过GPRS网络进行土壤墒情数据无线传输。通过上位机软件的开发设计,可实现多个终端节点土壤墒情信息的动态实时监测。试验结果表明,系统运行稳定,满足设计要求,能够为农业灌溉提供可靠的依据。Remote soil moisture monitoring system based on GPRS（ General Packet Radio Service） was designed to achieve real-time soil moisture content information and provide data for drought prediction and agricultural irrigation. It could be charged by solar panels. STC12C5A60S2 microcontroller was used as core controller in this system,and soil moisture data was sent through GPRS wireless transmission network. Through development and design of upper computer software,the system could carry out real-time monitoring of soil moisture content information from a plurality of terminal nodes. Results showed that the system had well stable performance,met design requirements and could provide reliable basis for agricultural irrigation.
