摘　　要：为保证避难硐室内各系统可靠运行,设计了一套避难硐室监控系统,监控系统以PLC为核心,同时采集硐室内温度、CO浓度、压风管道气体压力等相关参数,并对空气净化机、喷淋系统、O2装置等设备实现了自动控制,PLC通过光缆与地面中心站的监控设备通信。实践表明,实施该系统后,地面工作人员能对井下避难硐室实施有效地救援指挥。In this paper,a refuge chamber monitoring system was designed to ensure the reliable operation of every system inside the refuge chamber.The monitoring system adopted PLC as the core,it collected relevant parameters in refuge chamber simultaneously,such as temperature,CO concentration and gas pressure of ventilation pipeline,and it automatically controlled air cleaner,spray system,oxygen devices and other equipments.PLC communicated with the monitoring equipment of the ground center station through the fiber optic cable.The practice showed that the ground staff implemented effective rescue command for the underground refuge chamber by using this system.
