Embodiment 1

[0039] A valve hall equipment fault identification method provided by the embodiment of the present invention, such as figure 1 shown, including the following steps:

[0040] Step S1: Obtain a video stream of the device to be detected captured by the image acquisition device in real time, the video stream including: an infrared image and an ultraviolet image.

[0041] In the embodiment of the present invention, such as figure 2 As shown, when the user obtains the video stream of the device to be detected in real time captured by the image acquisition device in real time, he needs to enter the user name and password to log in. After the system logs in successfully, it initiates a login request to the network Take this as an example, not limited thereto, and select a corresponding network device in practical applications. After the device is successfully logged in, data initialization is performed, including: initializing TCP connection, video stream, infrared raw data stream, ...

Embodiment 2

[0120] An embodiment of the present invention provides a fault identification system for valve hall equipment, such as Figure 5 shown, including:

[0121] The image acquisition module 1 is used to acquire the video stream of the device to be detected captured by the image acquisition device in real time, and the video stream includes: infrared images and ultraviolet images; this module executes the method described in step S1 in Embodiment 1, where No longer.

[0122] The feature extraction module 2 is used to preprocess any frame of image in the video stream, and extract the feature data of the preprocessed image; this module executes the method described in step S2 in Embodiment 1, and will not repeat them here .

[0123] The fault detection module 3 is used to analyze the feature data by using at least one of the dynamic feature analysis algorithm and the heuristic classification algorithm, and judge whether there is a fault in the device to be detected; this module exec...

Embodiment 3

[0127] An embodiment of the present invention provides a terminal, such as Image 6 As shown, it includes: at least one processor 401 , such as a CPU (Central Processing Unit, central processing unit), at least one communication interface 403 , memory 404 , and at least one communication bus 402 . Wherein, the communication bus 402 is used to realize connection and communication between these components. Wherein, the communication interface 403 may include a display screen (Display) and a keyboard (Keyboard), and the optional communication interface 403 may also include a standard wired interface and a wireless interface. The memory 404 may be a high-speed RAM memory (Random Access Memory, volatile random access memory), or a non-volatile memory (non-volatile memory), such as at least one disk memory. Optionally, the memory 404 may also be at least one storage device located away from the aforementioned processor 401 . Wherein the processor 401 may execute the valve hall equ...

Abstract

The invention discloses a valve hall equipment fault identification method and system, and the method comprises the steps: obtaining a video stream, photographed by image collection equipment in realtime, of to-be-detected equipment, wherein the video stream comprises an infrared image and an ultraviolet image; preprocessing any frame of image in the video stream, and extracting feature data of the preprocessed image; analyzing the feature data by using at least one of a dynamic feature analysis algorithm and a heuristic classification algorithm, and judging whether the to-be-detected equipment has a fault or not; when a fault is detected, generating a fault type and positioning to a specific location. According to the invention, preprocessing and feature data extraction are carried out on an infrared image and an ultraviolet image; at least one of a dynamic feature analysis algorithm and a heuristic classification algorithm is used for analyzing the feature data, the fault type and the fault area position of the valve hall equipment are determined, and the reliability, scientificity and intelligence of operation and maintenance of the valve hall equipment are improved.

Description

technical field [0001] The invention relates to the technical field of electric power inspection, in particular to a fault identification method and system for valve hall equipment. Background technique [0002] At present, the time-based preventive test and regular maintenance of power equipment maintenance system, due to its own blindness and low level of maintenance, may cause damage to the good operation of the equipment or make the equipment "more repairs and worse". , especially complex and large-scale equipment such as UHV converter valves, converter transformers, and wall bushings. Since the commonly used preventive tests are usually carried out with low voltage applied offline, the low-voltage test cannot simulate the equipment in the UHV situation. Under the operating conditions; offline, it is impossible to simulate the thermal stress and other characteristics of the equipment; at the same time, the structure of the UHV converter valve and other equipment in the v...
