摘要
为解决目前我国农业上主要农作物群体存在的自动化灌溉程度不高问题,研制一款基于土壤墒情传感器MS10的田间无线精准灌溉系统。该系统主要有3个重要的组成部分:上位机监控系统、无线数据传输通道和下位机数据采集器。该系统可根据用户在上位机设置的土壤墒情上、下范围自动控制电磁阀的开闭使土壤墒情值始终保持在一个范围内。该传感器是根据频域反射法(FDR)原理制成,精度高、反应快。该系统总体运行稳定、功耗较低、操作方便简单,对于目前我国农业存在问题的解决针对性强,有较好的实用价值和市场推广价值。
To solve the problem of the low degree for automation irrigation of main farming groups in China,a field wireless precision irrigation system is designed based on soil moisture sensor MS10.The system is composed of three major components,including PC monitoring system,wireless data transmission channel and lower machine data acquisition.The system can automatically control the electromagnetic valve according to the range of soil moisture,which is set by the users at PC.The sensor is based on the frequency domain reflection（FDR） principle with high precision and fast response.The overall system is stable with low power consumption and easy operation,which has good practical value and marketing value.
