Similarly, the new group of buffers 1 to n can obtain the corresponding mean values 1 to n, the front-end acquisition device obtains the mean values of the mean values 1 to n again to serve as new threshold values, and updates the current first sound threshold value (i.e., the second sound threshold value) to the new threshold value, so as to realize the automatic updating of the sound threshold values in a circulating manner.
In this embodiment, the detection system implements automatic update of the sound threshold by the above method, does not depend on subjective judgment of an operator, is completely determined according to the sound data acquired during the operation of the device to be detected, and updates the sound threshold in real time according to the changed sound data, so that the obtained sound threshold is more suitable for the changed sound data, thereby improving reliability and precision of the determined sound threshold, more accurately judging whether the subsequently acquired sound data is abnormal, and further determining whether the device to be detected is abnormal according to the abnormal sound data, so as to improve accuracy of device detection.
