step 3, the controller inquires opening records of all the pollution discharge electromagnetic valves 4, if any one pollution discharge electromagnetic valve 4 is not opened once, the controller directly controls the corresponding pollution discharge electromagnetic valve 4 to be opened for pollution discharge, and closes the pollution discharge electromagnetic valve 4 after the preset pollution discharge time is reached, and meanwhile, the controller utilizes a timer to time the pollution discharge end time of the pollution discharge electromagnetic valve 4; if all the blow-down electromagnetic valves 4 are opened, the controller judges whether the actual time interval from the end of the last blow-down to the current time is equal to or greater than the preset blow-down time interval (the time interval is determined according to actual needs) or not for all the blow-down electromagnetic valves 4, if so, the controller directly controls the corresponding blow-down electromagnetic valves 4 to be opened for blow-down, closes the blow-down electromagnetic valves 4 after the preset blow-down time is reached, and simultaneously, the controller utilizes the timer to time the end time of the blow-down electromagnetic valves 4; if not, go to step 4;
step 4, the controller receives the actual air pressure information of the first air storage tank 8 and the second air storage tank 12 again, and compares the actual air pressure information with the preset maximum air pressure values of the corresponding air storage tanks respectively, and as long as the actual air pressure of one air storage tank is smaller than the corresponding preset maximum air pressure value, the controller controls the air compressor 1 to keep running; if the actual air pressures of the first air storage tank 8 and the second air storage tank 12 reach the corresponding preset maximum air pressure values, the controller controls the air compressor 1 to stop running;
step 5, the two pressure transmitters 5 respectively detect the actual air pressures of the first air storage tank 8 and the second air storage tank 12 and send detection signals to the controller, the controller respectively compares the actual air pressures of the first air storage tank 8 and the second air storage tank 12 with preset minimum air pressure values of corresponding air storage tanks, and the controller controls the air compressor 1 to start and keep running as long as the actual air pressure of one air storage tank is smaller than the corresponding preset minimum air pressure value;
