Maintenance system for industrial machinery

Abstract

A maintenance system for industrial machinery that allows for maintenance to be performed remotely, while minimizing the impact of the machinery on the surrounding environment. [Solution] A maintenance system for a work machine, comprising: a first control device having a first function management unit that calculates a first separation distance between a work machine and a communication terminal, and if it is determined that the first separation distance is greater than a threshold, generates specific work execution permission information that permits the execution of only specific maintenance work among maintenance work on the work machine; the communication terminal comprising a second communication device and a second control device, the second communication device acquiring the specific work execution permission information from the first communication device, and the second control device having a second function management unit that executes maintenance work restriction processing that restricts to the specific maintenance work based on the specific work execution permission information acquired via the second communication device.
