Abstract

The invention provides a screw fastening work management system, a screw fastening work quality determination device and a screw fastening work quality determination method, which are not influenced by surrounding external noise and can reliably determine the tightening work of an implemented screw according to the sound generated when the screw is tightened. In one embodiment of the present invention, acceleration data indicating the acceleration of a designated tool at the time of screw fastening work and sound data indicating sound generated by the designated tool at the time of screw fastening work are acquired, and sound to be analyzed is extracted from the sound data on the basis of the acceleration data. The quality of the screw fastening work is determined on the basis of the frequency included in the sound to be analyzed.

Description

technical field [0001] The present invention relates to a screw fastening work management system for managing screw fastening work by workers, a screw fastening work quality judging device, and a screw fastening work good or bad judging method. Background technique [0002] In the inspection work of passenger conveyors such as escalators and moving walkways (moving walkways), there is work such as tightening the bolts for fixing the pedals with a torque wrench (specified tool). In the tightening of the pedal fixing bolts, the tightening torque is determined. Generally, it is managed based on the worker's self-report whether or not the worker tightened with a predetermined torque using a torque wrench (designated tool). Therefore, there is a risk of poor workmanship, such as tightening with a tool other than a torque wrench, such as a wrench, or failure to perform tightening due to some important factors. [0003] The part tightened with the designated tool such as a torque...
