Title:
作業中ケーブルの保護監視システム、作業中ケーブルの保護監視方法及び作業中ケーブルの保護監視プログラム
Document Type and Number:
Japanese Patent JP7424487
Kind Code:
B2
Abstract:
To suppress 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, where in the working means stops movement and installment of the wire cable-shaped construction material when the abnormal event has been detected.
