The embodiment of the invention, which relates to the field of safety protection of coal mine working, discloses a method, device, and system for recognizing the pressure change of a roof plate and astorage medium. The method comprises: collecting sound samples of a fully mechanized mining work site; performing preliminary screening on the sound samples to obtain an initial sample library; preprocessing the sound sample data in the initial sample library to obtain a sample sound spectrum; extracting a feature vector corresponding to the sample sound spectrum and constructing a feature vectorlibrary; training the feature vector library to obtain an optimal roof sound codebook and establishing a recognition model library; and extracting a feature vector of a to-be-tested sample, identifying the to-be-tested sample by using a recognition model, calculating distances between the feature vector of the to-be-tested sample and all codons of the optimal roof sound codebook, determining the pressure change of the roof, and outputting an abnormal early-warning command. Therefore, problems of small coverage surface and inaccurate reading of the existing method for monitoring the pressure change of the roof in the prior art are solved.
Description
Technical field [0001] Example relates to the field of security operations coal present invention, particularly relates to a method of identifying the top plate of the pressure variation, means, system and storage medium. Background technique [0002] In recent years, our country coal mine accidents have occurred, the security situation is very grim. The most commonly occurring in the mining production process is the roof fall accident. Roof cave is a large area because changes in the surrounding rock, a worker for not recognizing the changes in rock stress on the job site were reinforced support caused casualties collapse phenomenon, to prevent the roof fall accident, should grasp the roadway roof pressure changes. Therefore monitoring the pressure variation roof sound, while the sound of breaking Method roof emitted pressure change is needed. [0003] At this stage the use of technology is the law of change in real-time monitoring through the roof pressure, the pressure of the ...
