MEMS technology-based mine wireless sensor acquisition system

针对煤矿设备状态有线监测系统的布线复杂、成本高、灵活性差等现状,为改善现有无线监测系统存在的通讯距离有限、抗干扰能力差、能耗高等问题,及解决已有监测系统数据无法接入共享的信息孤岛的问题,研究了一种基于MEMS技术的矿用无线传感采集系统。详细介绍了该系统的总体设计方案、采集器和集中器的硬件电路设计及软件实现(包括通讯报文的编制),并通过测试验证了系统的性能可靠。结果表明,该无线传感采集系统可灵活适应煤矿井上、井下复杂工作环境,实现煤矿设备的振动、温度信号的实时、远距离、无线传输,可为矿用设备的健康监测和故障诊断提供丰富的数据支撑。

Aiming at the complex wiring,high cost,and poor flexibility of the wired monitoring system for coal mine equipment status,and the limited communication distance,poor anti-interference ability,and high energy consumption of the current wireless monitoring system,as well as the information island of current monitoring system data,a wireless sensor acquisition system for mines based on MEMS technology is studied.The overall design plan of the system,the hardware circuit design and software implementation of the collector and concentrator(including the compilation of communication messages) are introduced in detail,and the reliability of the system is verified by tests.The results show that the wireless sensor acquisition system can flexibly adapt to the complex working environment of coal mines both on the surface and underground,realize real-time,long-distance,and wireless transmission of vibration and temperature signals of coal mine equipment,and can provide rich resources for data support of health monitoring and fault diagnosis of mining equipment.
