【摘要】 南疆的温带大陆性气候为棉花生长提供了良好的自然条件，该地区棉花种植范围广，但干旱少雨。为解决传统灌溉方式自动化程度低、水资源浪费严重等问题，本文以LoRa无线通信、传感器、远程控制等技术，设计了一套基于LoRa通信技术的农业灌溉控制系统。该系统采用高精度土壤墒情传感器，远程在线采集土壤温湿度，远程控制电磁阀开关等控制方式，获得作物最佳灌溉时间、灌溉水量。试验结果表明：应用该系统进行灌溉后，灌溉效率有了显著提高，灌溉均匀度可达95%以上，效果良好，可为大田灌溉提供参考。更多还原

【Abstract】 The temperate continental climate in southern Xinjiang provides good natural growth condition for cotton, this area has a large range of cotton cultivation, but it is dry and short of rain. In order to solve the problems such as low level of automation and serious waste of water resources in traditional irrigation methods, an agricultural irrigation control system based on Lo Ra communication technology was designed. This system can obtain the best irrigation time and best irrigation amount of water through high-precision soil moisture senor, remote online collection of soil temperature and humidity, remote control of solenoid valve switch. The test result show that the irrigation efficiency has been significantly improved after utilization of this system, the irrigation uniformity can reach 95% or above, which is a good effect and can provide references for irrigation of fields.更多还原
