基于ZigBee的田间灌溉自动测控系统设计

Field Irrigation Automatic Control System Design Based on ZigBee

针对目前我国农业灌溉用水量大、水资源利用效率低的问题,基于ZigBee无线通信技术设计了田间灌溉自动测控系统。通过湿度传感器HM1500测量土壤的水分,经下位机单片机系统采集,并通过ZigBee无线数传模块发送土壤水分含量数据至上位机;上位机能够实时监测现场数据,并通过与设定的土壤水分下限值进行比较,若达到灌溉要求则经ZigBee发送命令至下位机,启动水泵灌溉。设计的测控系统成本低、性能优,为节水灌溉系统的设计提供了借鉴。

According to the status of agriculture irrigation with much water consumption and low efficiency,the automatic observe and control system is designed based on ZigBee wireless technology. The lower monitor gets the soil moisture content by HM1500 and sends the data to upper monitor through ZigBee module. The upper monitor shows the information and compares the data with lower limit which is set,the start- up order is sent to the lower monitor with ZigBee transmission. The system has the character of low cost and good nature,and also provides a reference for water saving irrigation system design.
