Summary:灌区墒情实时监测是现代灌区灌溉管理中的必要部分和基础工作。该文设计了一种利用微功耗处理器的墒情监测仪,仅用2节1号干电池供电,结合GPRS（general packet radio service）数据传输至网络服务器处理分析,从而实现了区域分布式的墒情监测。本系统设计装载4层土壤水分/温度传感器和1层水势传感器,根据灌溉管理需要布设在作物根区不同深度;利用微处理器和设计电路进行土壤墒情等参数的采集、存储、传输和控制,每小时采集1次数据、每日将数据发送至网络服务器。通过在灌区不同区域典型作物生育期内实际运行1 a结果表明,该系统采用干电池或锂离子电池供电,体积小而便于在田间布设,不影响农田耕作,方便经济;监测数据能够及时传送至网络服务器以进行结果处理和灌溉管理。该文同时也对系统特点进行了总结,并指出对该系统进一步改进和研发方向。

It is a very important and fundamental work to monitor soil water status in real time for irrigation management in modern irrigation district. This paper presented a system with low cost and low power dissipation to monitor soil water status for areal irrigation management. The instrument of soil water monitoring contains a microcontroller-based system and is powered by 1# dry cell. All of the measurement data would be sent to web server through GPRS（general packet radio services） chipset assembled in it, for analysis and use in irrigation management based on each point of distributed framework. There were 4 sets of soil water content and temperature sensors and 1 set of water potential sensor designed, which could be installed at different depth in the crop root zone to meet the demand of irrigation management. However, it could be configured with less or more sensors in the system according to the channel values of the data ac
