单片机技术在温室灌溉系统中的应用

The Application of Microcontroller in Greenhouse Irrigation System

针对传统温室灌溉水资源利用率低、无法满足作物适时适量、按需灌溉的问题,以单片机技术为核心,结合传感器、遥控技术,设计一种具有参数遥控设定、土壤水分实时采集显示、土壤水分调节、超范围声光报警等功能的控制系统。经试验,该系统工作可靠、控制精度高,能够根据温室作物需求适时适量、按需、自动灌溉,能够节约用水、节约人工成本,具有良好的应用价值。

Against on low utilization ratio of water resources,Could not meet the timely and proper irrigation of crops in greenhouse irrigation,the paper designed a control system which put single chip technology as core and combined humidity sensor and remote control,it had some functions such as parameter setting by remote contro,real- time display,soil moisture adjustment,out of limit alarming etc.The test results show that the system with the advantages of good stabilization,better control performance,according to crop demand timely,adequate on- demand,automatic irrigation,reduce labor cost,it has a good application value.
