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 complex deployment, low transmission rate and difficult access to wireless sensor networks in existing mine monitoring system, a wireless sensor network mine monitoring system based on WiFi communication is designed. The system builds the hardware platform of mine monitoring based on STM32 chip and Wi Fi chip, uses 802.11 protocol to realize WiFi ad hoc network communication of sensor node, aggregates the measurement parameters of sensor node through router node and forwards it, finally transmits it to the monitoring center for mine monitoring .
