Abstract

The present invention discloses a system and method for monitoring the state of a bolt. The method comprises a step of collecting the bolt state parameter of an intelligent bolt through a bolt pretightening force tester, a step of calculating the pretightening force of the intelligent bolt according to the bolt state parameter, a step of comparing a prestored pretightening force measurement record and the pretightening force and determining whether the pretightening force of the intelligent bolt is in a preset safety range, and a step of uploading the pretightening force to a server when the judgment result is zero. According to the system and the method, the technical problem of hidden danger brought by the no control of the attenuation condition of the bolt pretightening force caused by the condition that the pretightening force of the bolt can be not accurately monitored is solved.

Description

technical field [0001] The invention relates to the technical field of electronic applications, in particular to a system and method for monitoring the state of bolts. Background technique [0002] Bolt pair is a common mechanical structure in mechanical applications. In specific application scenarios, taking railway structure assembly as an example, in various railway systems, most structures such as fastener systems, sound barrier systems or turnout areas are The assembly method of bolt pair is adopted. The assembly quality of the bolt pair interface mainly depends on the control of the bolt pre-tightening force. When the bolt does not reach the preset pre-tightening force when the bolt is tightened, the service life of the bolt pair will be reduced. At the same time, during the operation of the railway, if Insufficient monitoring of bolt pretightening force at key parts of key structures will lead to sudden failure of bolt pairs and affect driving safety. [0003] In th...
