Cable status management system

Abstract

This cable condition management system provides comprehensive monitoring of the progression of cable breakage and effectively suppresses equipment failures caused by cable malfunctions. [Solution] The cable condition management system 1 includes, as its main data, resistance value data representing the time-series change in the resistance value of the managed cable 2, and operation data representing the operating status of the managed device 110. The cable condition management device 400 is configured to communicate with the main data management device 120 via a network, and based on a data update signal transmitted to the main data management device 120, it acquires new main data to be stored in the storage unit 122 of the main data management device 120 and stores it in the cable condition storage unit 401. Subsequently, based on the main data stored in the cable condition storage unit 401, it estimates the progress of the break in the managed cable 2.

Claims
