摘要:智能灌溉是发展高效节能农业和园艺的主要方法。由于我国淡水资源的缺乏，因此要实现按需求、按时期、按灌溉量进行喷灌，既可以节省水资源，也可以节省劳动力，具有很强的实用性。这对于贯彻党中央的“建设节能型社会”的号召非常有利，有较好的经济效益和社会效益。
该系统能在无人值守时自动喷灌，在雨天和土壤水分充足时自动停止喷灌。该系统对节约水资源和人力很有意义。从影响作物生长环境入手，分析并确定是否灌溉的决定性因素，如：风速、湿度、PH、阴雨天等因素，以PLC作为控制器，设计一套自动灌溉的控制系统。此系统在满足非雨天、风速不高、湿度较低，再根据PH的大小来确定灌溉什么溶液，当达到土壤平衡状态的时候，自动停止喷灌，实现自动灌溉，达到节能环保的作用。

ABSTRACT:Intelligent irrigation is the main method of developing energy efficient agriculture and horticulture. Due to the lack of freshwater resources in China, therefore to realize the demand, according to the times, spray by irrigation amount, not only can save water resources, but also can save labor force, has a strong practical. To implement the Party Central Committee "the construction of energy-saving society" appeal is very favorable, with good economic benefit and social benefit.
To be punctual automatic sprinkling value in one of the system, automatic sprinkler irrigation in the rain and soil moisture is sufficient. This system is of significance for saving water resources and human. This paper starts from the influence of the crop growth environment, the decisive factor, analysis and to determine whether such as: wind speed, humidity, irrigation, PH, rainy days, with PLC as controller, design a set of automatic irrigation control system. Automatic irrigation, achieve energy-saving and environmental protection.
Keywords: PLC; Smart Irrigation; Automation; Sensor; Inverter
