Description

A dual-video remote control inspection automatic charging device for unattended substations

technical field

The present invention relates to an automatic charging device for dual-video remote control inspection in an unattended substation.

Background technique

With the continuous improvement of the application level of electric power technology and the development of the "big operation" of the power grid, more and more substations will become unattended substations after technological upgrading and transformation, which has effectively improved the production management level of the power system. At the same time It also puts forward new requirements for substation monitoring and management. After the "big operation" work is implemented, the automation system will transmit the collected data of the power grid equipment to the power monitoring room, and the control personnel will operate and manage the power grid. The limited video collection points cannot provide more on-site video information for the monitoring personnel. Human-on-duty substations cannot conduct on-duty inspections of on-site equipment, which is not conducive to timely judgment and handling of power grid accidents.

In order to solve the above problems, the existing technology uses unmanned substation remote control device for inspection, such as the patent of "Remote Control Inspection Device for Unattended Substation" with the patent number "CN 103686073A", which includes on-site acquisition device and monitoring room monitoring device, The on-site acquisition device is provided with a track on the site, on which an electronic eye that moves along the track and can make the camera rotate up and down, left and right, and the monitoring device in the monitoring room is connected to the on-site image acquisition device through the network. This patent can realize the daily video inspection of the equipment in the equipment area of the unattended substation and the multi-angle inspection of the appearance of the equipment when the equipment fails. Frequent replacement of batteries and multiple groups of batteries are used in rotation at the same time to ensure the normal operation of the equipment. However, battery replacement often needs to be done manually. People are on duty.

Both the control keyboard and the video display are connected to the single-chip microcomputer in the monitoring room, and the single-chip microcomputer is connected to the sending and receiving module in the monitoring room through a codec module.

The track is a U-shaped track.

The present invention is simple in structure, and double-video is added on the basis of the remote inspection device of unattended substation. The 90-degree video range passed by the inspection vehicle is collected by two cameras respectively, and there is no need to use the upper and lower ranges of the same position during the inspection process. Adjusting the resolution of the camera when the field of view is unclear can reduce the time for a single remote control tour and further improve the efficiency of the remote control tour of the device.
