Embodiment 1

[0045] In this embodiment, an equipment failure analysis system is first established. The equipment failure analysis system includes an infrared camera, a microprocessor and a communication module arranged at each target equipment, and a data analysis center. The microprocessor communicates with the infrared thermal imager respectively The imager and the communication module are connected by communication, and the communication module is connected by communication with the data analysis center. The infrared thermal imager is used to collect the original infrared thermal image of the target device and send it to the microprocessor. Images and images are sent to the data analysis center for equipment failure analysis, avoiding manual inspections, reducing labor costs, and improving inspection efficiency.

[0046] Infrared thermal imaging camera is a device that uses infrared thermal imaging technology to convert the image of the temperature distribution of the target object into ...

Abstract

The present invention belongs to the technical field of failure analysis, and specifically discloses a method for analyzing equipment failure, including the following steps: S1: Acquire the original infrared thermal image of the target equipment, and obtain the temperature data of the original infrared thermal image; S2: According to the temperature data, Perform temperature correction on the original infrared thermal image to obtain the temperature-corrected infrared thermal image; S3: Extract the contour of the temperature-corrected infrared thermal image to obtain several fault areas; S4: Obtain the fault judgment data of each fault area, and Judgment data to obtain failure analysis results. The invention solves the problems in the prior art of high labor cost input, low detection efficiency and failure to observe the details of the fault area, resulting in low fault analysis accuracy.

Description

technical field [0001] The invention belongs to the technical field of failure analysis, and in particular relates to an equipment failure analysis method. Background technique [0002] Power equipment mainly includes power generation equipment and power supply equipment. The planned maintenance system adopted by most power equipment in the power system has serious defects, such as frequent temporary maintenance, insufficient maintenance or excessive maintenance, and blind maintenance. Costly in equipment maintenance. How to reasonably arrange the maintenance of power equipment, save maintenance costs, reduce maintenance costs, and at the same time ensure that the system has high reliability is an important issue for system operators. [0003] Problems existing in the prior art: [0004] 1) Most of the maintenance of power equipment relies on manual inspection. This method has a large labor cost and low detection efficiency, and usually relies on experienced workers to ana...
