Distributed cable external damage prevention system based on video intelligent detection

Abstract

The invention discloses a distributed cable external damage prevention system based on intelligent video detection. A distributed optical fiber is adopted to realize a sensing trigger function of preventing external damage in the whole cable laying process along with cable laying. A standby camera is awakened by adopting the trigger signal. A scene at a preset monitoring position is captured. Thescene picture is grabbed to a target detection server. A behavior subject of the intrusion event is identified and acquired on the server, and a judgment is made that the behavior hazard. The system can realize all-weather unattended operation, fully covers a cable laying line, realizes standby awakening through vibration triggering, has relatively low power consumption, and is suitable for photovoltaic power supply and other field scenes. Particularly, the system can automatically identify the category of an invasion object by utilizing a target detection technology related to computer visionand image processing, and an effective monitoring means is provided for the detection of the intelligent power grid.

Description

technical field [0001] The invention relates to the field of computer vision technology and monitoring and protection of buried cables, in particular to a distributed cable anti-breakage system based on video intelligent detection. Background technique [0002] There are two main ways of laying optical cables: one is overhead laying, and the other is buried underground; since underground laying does not require materials such as poles, porcelain insulators, crossarms, and pull wires, it can greatly save investment, and taking into account Laying engineering conditions, environmental characteristics, etc., have become a trend in the future of optical cable erection. In particular, the buried armored power optical cable of the urban 10KV ring network power supply system has three major characteristics: high value, cable trench wiring, and widespread distribution in relatively remote areas, which leads to frequent external damage or thief attacks on the 10KV urban ring network ...

AI Technical Summary

Problems solved by technology

[0003] The anti-theft methods of optical cable mainly include covering the cover plate of the optical cable trench, manual fixed-point inspection, etc. For more remote places, there are few inspection personnel, which has led to a large number of criminals taking advantage of it.

In recent years, the use of sensors for optical cable anti-theft has emerged. The sensor installed together with the optical cable can be used to detect whether the line is complete, which can better prevent theft. The vibration generated when the heavy-duty vehicle passes has no ability to distinguish, and the vibration optical cable is laid in the form of parallel optical cable, the radiation range is limited, and the overall false alarm rate is high

[0004] The existing video surveillance technology is mainly for long-term monitoring of fixed points in key areas, which can be used to detect theft and damage in the early stage, and give corresponding early warning and treatment measures, but there are three problems: large amount of monitoring information Contradictions with limited monitoring personnel; large data storage volume, difficult analysis; passive monitoring, poor real-time response, and can only be dealt with after the event

[0006] However, this patent does not do further processing for video and photos, that is, target detection and recognition, etc., and has not been reasonably solved; therefore, the present invention now provides a solution for the deficiencies of the prior art
