Embodiment Construction

[0025] The present invention is described in detail below in conjunction with accompanying drawing:

[0026] This embodiment proposes a method and system for identifying equipment faults based on infrared temperature measurement technology. The infrared temperature measurement information acquisition module, that is, the infrared temperature measurement device, obtains information such as infrared detection images and infrared temperature measurement data, and uploads them to the big data analysis. Platform, the big data analysis platform processes, identifies and analyzes the data, compares it with the temperature threshold, and realizes real-time online alarm when an abnormality occurs.

[0027] Specific implementations, such as figure 1 Shown:

[0028] 1) Acquisition of infrared detection data information according to the infrared temperature measurement information acquisition module; the infrared temperature measurement information acquisition device combines the video i...

Abstract

The invention discloses an equipment fault identification system and method based on an infrared temperature measurement technology. A infrared temperature measurement information acquisition module acquires information of equipment; the acquired infrared temperature measurement information is uploaded to a big data analysis platform, and the big data analysis platform calculates a relative temperature difference of an equipment detection area; the calculated relative temperature difference of the equipment detection area is compared with a relative temperature difference of a preset typical fault case library which serves as a fault criterion, thereby judging the fault type corresponding to abnormal heat emission of the equipment; and the big data analysis platform displays the fault type obtained by analysis on a monitoring interface, and displays an infrared detection image of the equipment with abnormal heat emission on the monitoring interface. The invention realizes a system capable of automatically identifying a fault of electric power transmission and transformation equipment, considers influence of surrounding environmental conditions, and through a relative temperature difference judging method, automatically judges the running state and fault information of electrical equipment, and realizes on-line rapid detection of the running state of the electrical equipment.

Description

technical field [0001] The invention relates to the inspection industry of power transmission and transformation equipment, in particular to an equipment fault identification system and method based on infrared temperature measurement technology. Background technique [0002] The operating state of power transmission and transformation equipment directly affects the safety and efficiency of the power system. Once an abnormal working state occurs during operation, it will directly affect the power supply of the power grid. In addition to the large repair cost, it will also cause greater direct economic losses. loss. Temperature is an important parameter for the normal operation of equipment. When power equipment fails, there are obvious heat source parts and accompanied by thermal phenomena. [0003] For the potential failure of equipment, infrared detection technology is mostly used at present. Because infrared detection technology can obtain equipment operating status inf...
