Application of Wireless Sensor Network in Plant Growth Environmental Information Monitoring System

针对植物生长环境信息大滞后及大惯性的特点,基于WSN和低功耗ZigBee CC2430无线通信技术设计一个植物生长环境多环境参数监测系统。无线传感器网络实时采集和处理植物生长环境数据,由信息接收端保存,可进一步显示处理结果,从而完成动态信息监测任务。植物生长环境数据最终传送至系统的上位机监测中心,对环境数据进行统一管理,充分发挥无线传感器网络的路由监测作用。系统克服了有线传感器网络的局限性,组网灵活、节点成本低、网络容量大。同时,实时监测实验表明,该系统操作灵活,有较好的数据传输精度。由于良好的系统稳定性,使得其在植物生长环境信息监测中可以胜任多参数监测任务。

Focused on plant growth environment parameters information of large dead-time and inertia , in this paper , the amulti-parameters monitoring system of low-powerwireless communication technology based on WSN and ZigBee CC 2430 was designed .The collection part digitalizes the plant growth environment signal from the sensor and sends it out by WSN.At the reception part,the data is received, saved and displayed.The system collects environment information in monitoring center system to realize unified data management and monitoring function of ZigBee network. This system over-come the defect of wired sensor network and had many advantages , such as moving conveniently , flexible networking . The nodes is low-cost , network capability is large .Experimental result for temperature and humidity of plant growth en-vironment implies that the system is quite reliable and suitable , could bewidely work stably for automatic monitoring in plant growth environment .
