Power fault diagnosis and early warning system based on infrared spectrum technology

Abstract

The present invention provides a power fault diagnosis and early warning system based on the infrared spectrum technology. The system comprises an identification module, an analysis module and a diagnosis display module that are sequentially connected. The identification module comprises an image collection client and a processing circuit connected with the image collection client; the analysis module comprises an image intelligent analysis unit and a communication unit connected with the image intelligent analysis unit; and the diagnostic display module comprises an early warning unit and a display unit. The processing circuit is connected with the image intelligent analysis unit; the communication unit is connected with the diagnostic display module; and the image collection client collects infrared data, the infrared data is combined with equipment information collected in a visible light manner, and after being subjected to processing, the combined infrared data and equipment information is transmitted to the analysis module to form an equipment image automatic annotation model. According to the system provided by the present invention, by identifying the infrared spectrum of the power equipment, identification and annotation are carried out on the equipment, a bidirectional equipment type annotation model is established, and fault diagnosis of the power equipment is implemented.

Description

technical field [0001] The invention relates to the technical field of power fault diagnosis information measurement and early warning, in particular to a power fault diagnosis and early warning system based on infrared spectrum technology. Background technique [0002] With the rapid development of my country's economy, UHV, AC-DC hybrid, and massive access to new energy have become the inevitable development trends of the power grid. At present, my country's power grid coverage is very large, and the number of various substation equipment is also huge, such as substations, wires, towers, etc. It is obviously impossible to rely on manual maintenance, and the requirements for unified management and monitoring of these substations are also increased. On this basis, the rapid development of unattended substations also puts forward new requirements for their safe operation and management. Therefore, in order to improve the safety of personnel and equipment in unattended or le...

Problems solved by technology

[0005] However, in practical applications, through visible light, infrared, ultraviolet and other multi-spectral detection analysis and identification technologies, some problems in the current online monitoring of substation equipment can be fundamentally solved: the operating parameters of important equipment need to be monitored in real time, and manual inspection is used It is difficult to meet the real-time requirements. The sense of responsibility, work attitude and mental state of the inspectors have seriously affected the detection results; the operating status of many high-voltage equipment is difficult to convert into electrical signals, and they are easily affected by strong electromagnetic field interference during signal conversion and transmission. Diagnosis: The use of infrared to detect equipment is still at the simple application level of temperature records. It is not associated with equipment status, and historical data is difficult to store and retrieve. In addition, it is difficult for human eyes to distinguish the grayscale changes of subtle images, and it is difficult to analyze substation equipment objectively. degree of surface defects
