Title:
WORKING-STATE CABLE PROTECTION MONITORING SYSTEM, WORKING-STATE CABLE PROTECTION MONITORING METHOD, AND STORAGE MEDIUM HAVING STORED THEREIN WORKING-STATE CABLE PROTECTION MONITORING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/256478
Kind Code:
A1
Abstract:
This working-state cable protection monitoring system is for suppressing expansion of damage to a working-state cable due to work being continued without detecting breakage of the working-state cable when the breakage occurs. The working-state cable protection monitoring system is provided with: a working means that moves or installs a wire cable-shaped construction material including an optical fiber having at least one core; an interrogator that acquires environment information about each position of the construction material, sensed by the optical fiber; and an abnormal event detection means that, when the environment information acquired at each position of the construction material satisfies an abnormal pattern, detects an abnormal event at the position. The working means stops movement and installment of the wire cable-shaped construction material when the abnormal event has been detected.
