Substation intelligent robot inspection system and inspection method

Abstract

The invention discloses an intelligent robot inspection system and an intelligent robot inspection method for transformer station. The intelligent robot inspection system comprises a monitoring centre, which is connected to at least one station robot intelligent inspection system of a transformer station, and each station robot intelligent inspection system comprises at least one base station. At the same time, the transformer station is also provided with an environment acquisition subsystem inside and fixed point monitoring subsystems disposed at devices needed to be monitored in the transformer station. The intelligent inspection robot is provided with an intelligent inspection robot lower computer connected to a detection unit, the detection unit includes an infrared detection unit and an ultraviolet detection unit, and the ultraviolet detection unit includes an ultraviolet video server and an ultraviolet detection device. The intelligent robot inspection system and the intelligent robot inspection method have the advantages of optimized inspection path, excellent safety protection, high intelligent degree, all-time fault detection and seamless video monitor, thus providing brand new technology detection means and all-round safety guarantee for an intelligent transformer station.

Description

technical field [0001] The invention relates to the technical field of power system substation operation and maintenance, in particular to a substation intelligent robot inspection system and inspection method. Background technique [0002] For a long time, substation inspection work has been carried out manually. The traditional manual inspection method not only has shortcomings such as high labor intensity, low work efficiency, scattered detection quality, and single means, but also cannot be manually detected afterwards. The data is accurately and timely transmitted to the management information system for use in work. [0003] With the promotion of unattended substations, the inspection workload of substations is increasing, and the inspection rate and timeliness cannot be guaranteed. Especially after special geographical conditions such as plateaus and Gobi or extreme weather such as strong winds, fog, ice and snow, hail, thunderstorms, etc., manual inspections cannot ...

AI Technical Summary

Problems solved by technology

When inspecting specific equipment, the inspection robot does not optimize the path, and needs to take some unnecessary paths, which not only wastes battery energy, but also prolongs the inspection time of the inspection robot, and the detection efficiency is not high

[0007] 2. The pattern recognition function of the mentioned inspection robot is weak

The current status of high-voltage circuit breaker equipment in substations mostly depends on manual inspection or online monitoring. Manual inspection is labor-intensive and low in work efficiency; inspection / verification is not in place, and the docking cycle with the existing management information system is long; the mentioned inspection The online monitoring of the robot has fewer sampling signals and insufficient data; lack of records for the movement process; low analysis accuracy and lack of convincing diagnostic conclusions, etc.

[0008] 3. The mentioned inspection robot lacks a safety protection system

During the commissioning and normal inspection process of the inspection robot, especially when it is operated through wireless technology, due to the lack of effective protection means, when the inspection robot encounters an unexpected situation, the shell collides with the equipment and is damaged.

[0009] 4. The mentioned inspection robot cannot detect the early failure of the equipment in advance

Infrared detection is easily affected by infrared radiation in the environment, especially solar radiation, so infrared detection generally cannot be carried out during the day, which causes some equipment failures to be detected and discovered in time; infrared detection usually detects late-stage failures of equipment, and cannot detect early-stage early warning

[0010] 5. The mentioned inspection robot cannot be effectively combined with the traditional video surveillance system

There is still a large monitoring blind spot, and it is difficult to truly meet the requirements of video inspection and all-round coverage

[0011] 6. The mentioned inspection robot cannot cooperate with the sequence control system

Existing substation inspection robots cannot realize automatic identification of equipment status after switching operations, cannot interact with the substation sequence control platform, and cannot realize the sequence control process of switching operations
