Zusammenfassung: | The invention relates to a sound field induction type high-pressure gas leakage alarm system and method, and the gas leakage alarm system comprises a frame body, a plurality of ultrasonic receiving devices, a signal processor, an indicating lamp, an alarm, and a display. The high-pressure gas leakage detection device is used for preprocessing the original sound wave signals acquired by each ultrasonic receiving device, integrating the preprocessed sound wave signals into a test signal set, comparing the test signal set with signals in a preset ultrasonic audio library, carrying out qualitative judgment on high-pressure gas leakage, and judging whether the high-pressure gas leakage occurs or not. And inputting the corresponding test signal set into a pre-trained neural network model, and calculating through the pre-trained neural network model to obtain a final leakage position coordinate. Compared with the prior art, whether high-pressure gas leakage occurs or not can be quickly judged, meanwhile, the positio |
