采煤机无线监测系统的设计

Design of Wireless Monitoring System of Shearer

  • 摘要: 为准确获取采煤机的运行状态参数,提出了一种采煤机无线监测系统的设计方案。该系统在采煤机机身的指定部位安装具有特定功能的无线传感器节点,用于采集采煤机的工作信号,该信号由DSP处理后,通过无线MESH网络传至无线网桥AP,再通过光纤传送到中心计算机,中心计算机上的分析软件对接收到的采煤机的工作信号进行分析,并根据预先设定的门限值进行报警或其它处理。现场试验结果表明,该系统运行良好,无线MESH网络的信号强度能够满足采煤机无线监测系统的要求。

     

    Abstract: In order to obtain parameters of running state of shearer accurately, a design scheme of wireless monitoring system of shearer was proposed. The wireless sensor nodes with specific-function are installed on appointed part of shearer frame,which are used to collect working signal of shearer. The signal is real-timely processed by DSP and is transmitted to wireless bridge AP by wireless MESH network, then it is transmitted to center computer by fiber. The working signal of shearer is analyzed by software of the center computer which makes alarming or other processing according to set threshold. The result of actual test showed that the system runs well and the signal intensity of wireless network can meet with requirements of wireless monitoring system of shearer.
