Cable anti-theft monitoring method and system and computer readable storage medium

Abstract

The invention relates to a cable anti-theft monitoring method and system and a computer readable storage medium. The method comprises the following steps: coupling pulsed light to a single-mode optical fiber to generate backward Rayleigh scattering in the single-mode optical fiber; receiving the backward Rayleigh scattering reflected by the single-mode optical fiber, and acquiring a vibration signal distributed along the single-mode optical fiber according to the pulsed light and the backward Rayleigh scattering; obtaining an intrusion position of a to-be-tested cable according to the pulsed light and the backward Rayleigh scattering, and inputting the vibration signal into a prediction model to obtain an intrusion type of the to-be-tested cable; according to the intrusion position and theintrusion type, outputting corresponding alarm information according to a preset alarm strategy. The intrusion type of intrusion time can be accurately acquired by using a prediction model, the identification accuracy of an intrusion event is improved, and meanwhile, a corresponding alarm signal can be output according to the intrusion event to warn a worker.

Description

technical field [0001] The invention relates to the technical field of cable monitoring, in particular to a cable anti-theft monitoring method and system, and a computer-readable storage medium. Background technique [0002] Cable trenches are widely distributed and have long distances. Fires cause cable breakage, short circuit, equipment tripping, power outages and other faults, which not only cause economic losses to power users, but also pose a serious threat to the safe operation of the power grid. [0003] Traditionally, the cable can be monitored based on electrical parameters such as cable leakage current measurement or outer layer capacitance measurement. The disadvantage is that it can only be monitored after the line is damaged, and it cannot be monitored or identified after a power failure. The intrusion location and intrusion type of the intrusion event; secondly, the cable detection can be realized based on the optical fiber vibration sensing monitoring technolo...

[0002] The distribution of cable trenches is wide and the distance is long. Fires cause cable breakage, short circuit, equipment tripping, power outages and other failures, which not only cause economic losses to power users, but also pose a serious threat to the safe operation of the power grid.

[0003] Traditionally, the cable can be monitored based on electrical parameters such as cable leakage current measurement or outer layer capacitance measurement. The disadvantage is that it can only be monitored after the line is damaged, and it cannot be monitored or identified after a power failure. The intrusion location and intrusion type of the intrusion event; secondly, the detection of the cable can be realized based on the optical fiber vibration sensing monitoring technology, and the intrusion location and intrusion type of multiple intrusion events cannot be identified
