基于WiFi通信的矿井监测无线传感器网络研究

Research on Mine Monitoring Wireless Sensor Network Based on WiFi Communication

针对现有矿井监测系统中无线传感器网络部署复杂、传输速率低、难以接入等问题,设计了一种基于WiFi通信的无线传感器网络矿井监测系统。该系统基于STM32芯片和Wi Fi芯片搭建矿井监测的硬件平台,利用802.11协议实现传感器节点的WiFi自组网通信,通过路由器节点汇聚传感器节点的测量参数并进行转发,最终传输至监测中心实现矿井监测。

Aiming at the problems of low data-rate, complex deployment, access difficulties and other issues on the traditional mine information monitoring system （MIMS）, a new MIMS based on WiFi wireless sensor networks is designed. The hardware platform of MIMS is constructed based on STM32 and WiFi chips, it uses 802.11 protocols to realize the WiFi communication between wireless sensors, and aggregates and forwards the wireless data with the help of the router nodes, ultimately transmitted those packets to the remote monitoring center.
