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 order to ensure the reliable operation of each system in the evacuation chamber, a set of evacuation chamber monitoring system is designed. The monitoring system takes PLC as the core and collects relevant parameters such as indoor temperature, CO concentration and gas pressure in the compressed air pipeline, , Sprinkler system, O2 devices and other equipment to achieve automatic control, PLC through the optical cable and the ground station monitoring equipment communication. Practice shows that the implementation of the system, the ground staff to underground rescue chambers to implement effective rescue command.
