摘要
针对矿井避难硐室应急响应流程复杂、操作难度大、管理培训困难等问题,通过数学建模、仿真模拟、硬件编程等方式,对避难硐室自动控制系统进行研究,提出了自动控制系统的组成方式及基于该控制系统的避难硐室应急响应流程。实现了对避难硐室电力系统和压风系统的自动状态检测及切换,得出了100人避险条件下的压风切换阈值为0.48 MPa。实现了压风量、温度、O2浓度、CO2浓度等参数的自动调节,并通过Simulink软件仿真模拟得出:该控制系统在100人避险条件下,O2、CO2、温度超限恢复响应时间分别为11.7、15.0、13.3 min。同时利用人机界面,对整个硐室进行直观、有效地控制。运用该系统,可以有效提升矿井避难硐室应急响应效率,降低操作、管理及培训难度。
According to the complicated emergency response procedure,high difficult operation,difficult management and training and other problems of the mine refuge chamber,the mathematic modeling,analogue simulation,hardware programming and other method were applied to the study on the automatic control system of the mine refuge chamber. The composition mode of the automatic control system and the emergency response procedure of the refuge chamber were provided. The automatic status detection and switching of the refuge chamber electric power system and compressed air system were realized and the compressed air switching threshold value was 0.48 MPa under the condition of 100 persons in the refuge chamber. The automatic adjustment of the compressed air volume,temperature,oxygen concentration,carbon dioxide concentration and other parameters were realized. The Simulink similar simulation showed that under the condition of100 persons in the refuge chamber,the temperature overlimite response time of the control system was 11.7,15.0 and 13.3 min individually. A man-machine interface was applied to the direct and effective control of the whole chamber. With the application of the system,the emergency response efficiency of the mine refuge chamber could be effectively improved and the difficulty of the operation,management and training could be reduced.
