Description

A detection system for abnormal appearance of substation equipment

technical field

The utility model relates to a detection system for abnormal appearance of substation equipment.

Background technique

The current substation status monitoring system monitors the operating status of the substation equipment through real-time monitoring of the data collected from the power equipment, but it cannot directly detect the possible abnormalities in the appearance of the equipment; Plastic, oil leakage of transformer equipment, and cracks on the surface of equipment will bring hidden dangers to the safety of substations and should be removed or maintained in time. Relying solely on manual inspection, due to the high-voltage environment of the substation, there are many unsafe factors, and it is difficult to find problems in time due to the inspection of the current substation personnel at a specific time. At present, there is no device related to the abnormal detection of the appearance of electric equipment.

Utility model content

The purpose of the utility model is to solve the above problems, and provide a simple structure, safe and convenient, and can quickly and effectively identify abnormal appearance detection system of substation equipment with abnormal appearance.

In order to achieve the above object, the utility model adopts the following technical solutions:

A substation equipment appearance abnormality detection system, which includes a substation equipment image acquisition module, which is installed on the pan/tilt of the line patrol car and connected to the control module. The control module completes the movement control of the trolley and the pan/tilt control, and the wireless communication module Responsible for the transmission of image information, the image information is transmitted to the background processing module, and the background processing module is connected with the alarm module.

The image acquisition module includes a camera and a memory, the images collected by the camera are stored in the memory, and the memory completes the temporary storage of image information.

The control module is an embedded system, which completes the motion control of the car and the control of the pan-tilt.

The wireless communication system completes the communication between the image storage device and the background processing module, and transmits the image information to the background processing system in different environments.

The background processing system is a computer, which is responsible for the abnormal detection of the image. According to the image information transmitted by the wireless communication system, it detects the abnormal area on the image and gives an alarm message.

The utility model provides a detection system for abnormal appearance of substation equipment. The system is mainly composed of (1) substation equipment image acquisition module; (2) control module; (3) wireless communication module; (4) background processing module; (5) alarm module. Among them, the substation equipment image acquisition module mainly includes image acquisition equipment and image storage equipment. The control module mainly includes two parts: motion control and pan/tilt control. Among them, the motion control is mainly responsible for the parking position of the car, and the pan/tilt controls the shooting angle of the camera. The wireless communication module mainly sends the image information obtained by the acquisition device to the background processor through the wireless transmission device. The background processing module, based on the computer platform, mainly completes the anomaly detection function. The software compares the current image of the device with the normal image saved in the database, and uses a robust anomaly detection algorithm to extract the changes in the current image relative to the reference image. area, and calculate the changed position and area. After the background processing module completes the detection of the abnormal area, the alarm module gives a corresponding warning through certain judgment criteria.

The working process of the utility model is as follows: firstly, the image acquisition device selects a zoom camera, and when collecting images, selects a suitable focal length for different targets, and uses the same focal length for the equipment at the same position, through the motion control system and the pan-tilt control system , so that the camera collects images at a fixed position and a fixed angle (less than a certain error). Then put the captured device into the image storage device.

After obtaining the image, the image information in the image storage device is sent to the background processor by the wireless router through the wireless transmission system.

The background processing module compares the currently received equipment image with the normal reference image in the database, and obtains the changed area information through the substation equipment appearance anomaly detection program.

After the detection process is completed, the alarm system will give corresponding warnings based on the current abnormal detection results and based on a certain alarm mechanism, and notify the substation staff.

The system mainly collects images of different devices with appropriate focal lengths through motion control and PTZ control, transmits them to the background processor through the wireless network transmission system, and uses substation equipment anomaly detection software to detect the current status of equipment, such as An abnormal area is found, and an alarm signal is given according to certain rules. During the day, the trolley inspects many times, so as to detect abnormal appearance of the equipment in time, and provide guarantee for the safe production of the substation.

The beneficial effects of the utility model are: the utility model proposes an abnormal appearance identification system based on visual detection technology, based on the substation inspection robot, which can replace manual on-site inspection in the substation, and improves the safety of equipment inspection work; Through the wireless communication device, the background processing software can be placed in a safe place, so that the substation staff can monitor the equipment status safely and in real time; through the abnormal appearance detection software of the substation equipment, it can automatically detect the abnormality of the appearance of the equipment. In the state, the alarm signal is sent out in time.
