When the size of the leak hole is smaller and the Reynolds number is higher, the flushed gas forms turbulence, the turbulence generates sound waves with certain frequency near the leak hole, the frequency of sound wave vibration is related to the size of the leak hole, when the leak hole is larger, the human ear can hear the air leakage sound, when the leak hole is smaller and the frequency of the sound waves is more than 20kHz, the human ear can not hear the sound waves, but the sound waves can be transmitted in the air and are called no-load ultrasonic waves, the sound waves can be detected by the leakage detector, the central controller judges whether the sound waves are pipeline leakage or not according to signals transmitted by the leakage detector through the fourth wireless communication device, if the leakage signals are detected, the central controller controls the water pump unit driver to close the water pump unit, the waste of continuous leakage of water resources is avoided, and meanwhile, the central controller also sends preset leakage reminding information to a user terminal and a water supply office server through the WIFI wireless communication device, on one hand, related workers are reminded to process in time, on the other hand, the emotion of the user is pacified, and the reason is informed; if the leakage detector does not detect the pipeline leakage, the central controller sends preset pipeline blockage information to the water supply office server and the user terminal; the design can facilitate the working personnel to know which kind of problem is specific, and facilitates the later treatment and solution of the problem; meanwhile, after a problem occurs, the central controller controls the voice alarm driver to start the voice alarm to broadcast preset reminding voice of the corresponding problem, and the purpose of reminding workers is achieved by matching alarm information; after the voice alarm is started, the timing device starts timing, and after the preset time is reached, the central controller controls the voice alarm driver to close the voice alarm, so that the interference of continuous operation on workers is avoided.
