基于无线传感器网络的农田监测系统

摘要

In recent years, with the speeding up of the socialist new rural construction, the development of modern agriculture and precision agriculture, demand for farmland monitoring technology is also increasing. Aiming at the characteristics of the farmland monitoring, TinyOS technology as the core, sensor gateway LM-430 as the control unit, processing unit through RS-485 serial port receiving summary data gateway node, analysis of farmland state and take corresponded measures, and use the TinyDB database management program for storage. The test verifies that system is real-time, reliable wireless monitoring of various meteorological indexes and meet the field monitoring data collection, transmission and processing requirement, for the implementation of agricultural complex environment provides scientific basis for accurate control.%近年来随着社会主义新农村建设进程的加快，现代农业与精准农业的发展，对农田监测技术的要求也不断提高。本文针对农田监测的特点，以TinyOS技术为核心，以LM-430传感器网关为控制单元，处理单元通过RS-485串口接收网关节点汇总数据，分析农田状态并采取相应措施，并通过TinyDB数据库管理程序进行存储。经测试，该系统能够实时可靠地对多种气象指标进行无线监测，满足农田监测数据的采集、传输及处理的要求，为实施农业复杂环境的精准调控提供了科学依据。
