Control system and control method for improving mine fire gas monitoring instantaneity

The invention relates to a control system and control method for improving mine fire gas monitoring instantaneity. The control system comprises a flow detection module and a control module, the flow detection module is arranged on a gas monitoring pipeline, and the control module is connected with the flow detection module in a sampling mode and provided with control signal output ports used for controlling and being connected with all reversing valves. The control module obtains time needed for emptying beam tubes and then controls the beam tubes to be emptied at the same time. When corresponding time needed for emptying a certain beam tube is up, gas in the beam tube is detected, and gas of all the beam tubes are sequentially detected. Compared with a conventional mode that emptying time is judged according to use experience and then four times of time detection are sequentially conducted, the control mode provided in the method can greatly save cost and time, and natural fire monitoring instantaneity of a
