粮库检测系统的网络设计

The Network Design of Detection System for Grain Storage

针对大型粮库粮食存储环境监测点分散的现状,设计一种树状拓扑结构的无线传感器网络中央监测系统。该系统以ZigBee无线传输技术为核心,结合温湿度传感器模块,构成无线传感器网络检测子节点。系统能够对现场环境实时检测,同时通过路由节点将检测到的数据上传给上位机,其中路由节点采用无线传输方式与终端节点进行通讯,使得现场检测到的数据能够实时传送给中央监控计算机,最终实现粮库内部的多点检测及和实时监控。

In view of the present situation that large grain storage environment monitoring points are scattered, this paper has designed one kind of wireless sensor network central monitoring system of a tree topology. The system uses the Zig- Bee wireless transmission technology as the core, and combines with the temperature and humidity sensor module to make up of network node detection of wireless sensor. The system can make real-time detection of field environment, and transfer the data detected through the routing node to the host computer. The routing nodes communicate with the terminal node by wireless communication, and the detected data can be transmitted in real time to the central monitoring computer. Finally the system realizes the multi-point grain internal detection and real--time monitoring.
