摘要
为解决目前农田自动监测系统存在的布线困难、成本高和灵活性差等问题,本文构建了基于无线传感器网络的农田信息远程监测系统。该系统的传感器节点负责农田土壤墒情、温度、湿度、光照强度和二氧化碳浓度的采集功能,并通过无线传感网络将数据发送给汇聚节点,汇聚节点通过RS232串口将数据传送给数据监测中心。传感器节点的硬件主要由一个传感器模块、处理模块、无线通信模块和电源模块组成。试验证明,该系统可以实现了对农田信息的远程实时监测,有效提高农田管理的信息化和自动化水平,大大提高了劳动效率,降低了人工劳动强度。
Some problems of Field Informationss Remote Monitoring System, such as wiring difficulties,low performance-price ratio and short of flexibility, still exist. This paper analyzes the limitations of the existing Field Information monitoring systems and the new Field information monitoring system based on wireless sensor networks.The proposed system uses sensor nodes to obtain data of soil moisture,temperature,humidity,light intensity and carbon dioxide concentration in the fields; a sink node is used to collect data from the sensor nodes through a wireless sensor network and monitoring center to process data downloaded from the sink node through RS232 serial port. The hardware platform of the sensor node is composed of a sensor module,a processing module, wireless communication and a power module.Tests showed that the system can be used for real-time monitoring in the field, improve greatly informational and automatic level of field information management. Laborintensity is reduced, and working efficiency is greatly improved.
