Three-dimensional visual unattended transformer substation intelligent linkage system based on video fusion

Abstract

The invention relates to a three-dimensional visual unattended substation intelligent linkage system based on video fusion. The system comprises a 3D video live-action fusion subsystem, an intelligentinspection subsystem, a sensor subsystem, a rail machine inspection subsystem, a door magnet and perimeter alarm subsystem, a dome camera linkage subsystem, a flame recognition and early warning subsystem and a monitoring center, and all the subsystems are interconnected and intercommunicated with the monitoring center. The three-dimensional visual unattended substation intelligent linkage systemis realized by fusing three-dimensional videos, the all-weather, omnibearing and 24-hour uninterrupted intelligent monitoring of a substation is realized, and the arbitrary browsing and viewing of athree-dimensional real scene of the substation and alarm prompting of faults in the substation are realized; a worker can watch the videos in the monitoring room, the real-time monitoring and dispatching command of a plurality of substations under administration are achieved, the worker does not need to inspect power transformation facilities and equipment every day, and the monitoring capacity and the working efficiency are improved.

Description

technical field [0001] The invention relates to video image fusion processing and the field of automatic control, specifically to the fusion of video data and three-dimensional models, and through the interconnection, intercommunication and mutual control of various sensors, the panoramic three-dimensional monitoring of substations is realized, unattended around the clock, intelligent identification of abnormalities, and timely Alarm linkage processing. Background technique [0002] As my country's high-speed rail construction is in full swing, there are currently about thousands of substations in my country's high-speed rail system, providing stable and reliable power supply and ensuring the safe and efficient operation of the entire railway network. In order to ensure the stability of the substation, these substations need to arrange staff to inspect and maintain each power supply equipment in the entire power grid, and record and analyze the overall equipment parameters o...

Problems solved by technology

There is a certain time interval in this inspection method, which makes the substation in a state of laissez-faire and unmanaged monitoring for a long time. Taking measures in time will cause power failure and incalculable losses, and this inspection method has problems such as requiring a large number of personnel, not responding in time, and being greatly affected by the weather

[0004] In order to improve the monitoring effect and all-weather monitoring, some intelligent monitoring systems have been put into use at present. However, most of the existing intelligent monitoring systems are monitored by installing multiple cameras in the substation. The on-duty staff stares at the screen 24 / 7 to find abnormalities, and once an accident occurs, such as a fire, the system cannot automatically identify it, cannot actively call the police, and cannot further deal with dangerous situations in substations, thereby aggravating accident losses

After the existing intelligent detection system obtains single-channel video information through multiple cameras, it often presents video images in nine-square or sixteen-square grids, which cannot correlate the video information. These chaotic information will easily cause visual fatigue to the staff on duty.

The video adopts a two-dimensional mode, which is not conducive to the overall control of the substation site, so that it is impossible to reasonably control the existing resources of the substation and take appropriate measures to deal with the danger

[0005] In the existing technology, illegal personnel are prevented from entering through the staff on duty or through the access control system. However, these methods cause a waste of human resources, and cannot completely avoid illegal intrusion

When an illegal intrusion occurs, the system cannot detect and feed back to the monitoring center in time, nor can it track and record the activity track of the intruder

When illegal intruders steal or destroy the equipment of the substation, they cannot report to the police in time, resulting in serious failure of power supply
