基于低功耗无线传感器网络的煤矿井下环境监测系统设计

Design on Coal Mine Environment Monitoring System Based on Lowpower Wireless Sensor Network

针对现有煤矿井下环境有线监测方式成本高、接线复杂的问题,提出将低功耗无线传感器网络技术应用于井下监测系统,设置多个传感器节点采集多种数据,各节点以无线方式传输数据,提出改进型基于地理位置的路由协议构成MESH结构自组织网络,系统低功耗运行实现远程监测。该系统具有通信距离远、成本低、使用灵活、数据测量准确、抗干扰、使用寿命长等优点。

To solve the problem of the difficult to set up the network and high costs in existing coalmine environment monitoring methods, the low-power wireless sensor network technology for coalmine monitoring system is proposed. The system collects a variety of data by setting a plurality of sensor nodes. Each node transmits wireless data. Self-organizing networks with MESH structure are constituted. And it improved routing protocol based on geographic location. The system monitor real- time remote data in low-power operation, and the system is low cost, flexible, accurate, long survival.
