The invention relates to the technical field of noise detection, in particular to distributed acoustic detection equipment and a detection method thereof. The method comprises the following steps: calculating the credibility based on the noise decibel of each piece of distributed acoustic detection equipment and the distance from the equipment to a sound source; calculating the difference degree of any two distributed acoustic detection devices in each group based on the noise frequency of each distributed acoustic detection device; obtaining a difference coefficient according to a ratio of any two difference degrees in each group; calculating noise evaluation of the two groups of distributed acoustic detection equipment based on the difference degree of the two groups of distributed acoustic detection equipment with the maximum credibility; if the noise evaluation is greater than a second threshold value, obtaining the noise evaluation as a noise detection result; and if the noise evaluation is smaller than a second threshold value, calculating the noise degree of the two groups of distributed acoustic detection equipment based on the difference coefficient of the two groups of distributed acoustic detection equipment with the maximum credibility and the noise evaluation, and recording the noise degree as a noise detection result. The noise condition can be accurately detected.
Description
technical field [0001] The invention relates to the technical field of noise detection, in particular to a distributed acoustic detection device and a detection method thereof. Background technique [0002] Noise usually refers to random random interference. Noise detection is the detection activity of the sound and its source that interfere with people's life, study and work. Existing noise comes from a wide range of sources, including domestic noise, road traffic noise, factory noise, and so on. Among them, when the machines in the factory are working, there will be noise, which will not only damage the hearing of the workers, but also affect the surrounding environment. Therefore, it is necessary to detect the noise in the factory. The existing noise detection method uses a small number of noise detectors, and the sound is lost during the propagation process, which leads to unsatisfactory noise detection results. Contents of the invention [0003] In order to solve th...
