Study on automatic control system of mine refuge chamber

Aceording to the comlicated emergency response procedure, igh dificult operation d ficult management and raining and other problems of the mine refuge chamibe,the mathem atic modeling,analogue sinulation.hardware programming and other method were applied to the study on the automatic control system of themine refuge chamber. The compo.stion nodeof the automatic conrolsystem and the emergency response procedure of the refuge chamboer were provided. The automati status detection and swithing of the refuge chamber electic power system and compressed air system were realied and the compressed airswithigtreaold alue was 0.48 MfPa under the condion of 1 persons in the refuge chamber.The automaic adjustment of the compressed air volume temperature oxygen concentration.,carbon dioxide concentration and other parameters were realized. The Sinmulik sinilarsinulation showed thatunder the condtion of00 persons in the refuge chamberthe temperature overimite respons e time of the control system was1715.0 and 13.3 min individuall , A man-machine interace was appid to the direct and efectve control of the whole chanber . with the application of the system.the energency response eficiencyof the mine refge chamber could be efecivly improved and the difficulty of the operation,management and training could be reduced.
