基于无线传感器网络的农田灌溉远程监控系统
Remote farmland irrigation monitoring system based on wireless sensor networks
摘要
Abstract
A remote irrigation monitoring system,in which soil moisture monitoring,pump and electromagnetic valve control and data remote management are integrated,was designed to realizes automatic control on irrigation for saving water.In the system,the wireless sensor network nodes were developed with the 433 MHz core frequency to accomplish a real - time monitoring for soil temperature and moisture in farmland.Base stations were built based on ARM9 microprocessor S3C2410,where the operation of pumps and electromagnetic valves was controlled by comparing with the stored thresholds in the database.The remote real-time monitoring of irrigation system was conducted through GPRS wireless transmission ,and the Citect configuration software was used in the remote monitoring center for the data and HMI (human-machine interface) management.In the application,four groups of wireless sensor nodes were chosen.The soil temperatures and moistures in 25 cm depth were acquired by the system in the 30 min data sampling interval.The operation of the pumps and valves in the base stations was controlled according to the soil information just obtained.This information was also transmitted to the remote monitoring center through the GPRS wireless network.It was showed that the system is flexible in use,low power consumption and with a friendly HMI.It can better meet the demand on application of farmland ir- rigation remote monitoring.关键词
