摘　　要：针对传统的灌溉控制器布线多、施工难,且采用RS485与计算机通信时距离受限等问题,设计和实现了一个基于Wi-Fi的自动灌溉控制器,能在远程计算机上以Web网页的方式实时控制灌溉、显示监测信息。该控制器可同时测量8路模拟量、3路数字量,并可以控制7路交流电磁阀。该灌溉控制器具有友好的监测操作界面,并且实现了广泛的信息共享。因此,在农业领域具有广阔的应用前景。Traditional irrigation controllers often have many problems such as routing too much, difficulty in constructing, restricted in long communication distance when adopting RS485 with computer. This paper designs and implements an automatic irrigation controller based on Wi-Fi, which realizes a real-time control and shows the monitoring information by way of web pages in a remote computer. This controller can simultaneously measure eight analog, three digital signals, and control seven alternating current electromagnetic valves. The irrigation controller has a friendly interface to monitor and control, and it achieves a wide range of information sharing. So it will have a wide application prospect in agriculture.
