The embodiment of the invention relates to the technical field of data processing, in particular to a bolt tightening detection method, device and system and a storage medium. The method comprises thefollowing steps: receiving time sequence process data which is transmitted from the outside and is generated in the process of tightening a current bolt; screening the time sequence process data to obtain first data generated in an actual tightening stage; extracting similarity characteristics in the first data, and forming a similarity characteristic matrix; inputting the similarity characteristic matrix into a pre-established classifier model, classifying the current bolt tightening state, and obtaining a classification result; and displaying a classification result, and sending an alarm signal when determining that the bolt tightening state is in an abnormal state according to the classification result. Through the mode, not only can the normal or abnormal state of each bolt be accurately judged, but also the abnormal bolt fault type can be determined.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular to a bolt tightening detection method, device, system and storage medium. Background technique [0002] Bolts are indispensable fasteners in modern assembly processes. The bolt and connection process has excellent properties such as high connection strength, detachability, easy repeatability, interchangeability, etc., and has a high degree of freedom. Mass production can be realized through standardization, and the cost is low. It plays an important role in the industrial field and is called "the rice of industry". Due to its large-scale application in the manufacturing industry, the quality of bolt tightening directly affects the safety and reliability of the final product. Various accidents or recalls caused by improper bolt tightening not only cause huge economic losses, but also may cause potential safety hazards for personnel. How to eff...
