Temperature detection method and system based on substation equipment and storage medium

Abstract

The invention discloses a temperature detection method and system based on transformer substation equipment and a storage medium. The temperature detection method based on the transformer substation equipment comprises the steps: acquiring an infrared imaging picture; extracting a to-be-detected area of the substation equipment according to the infrared imaging picture; acquiring a temperature change curve of the to-be-detected area in a preset time range, and determining a relative temperature difference according to the temperature change curve; and if the relative temperature difference is greater than a preset temperature difference threshold, outputting abnormal information. After the to-be-detected area of the substation equipment in the infrared imaging picture is extracted, the corresponding temperature change curve is obtained according to the to-be-detected area, then the relative temperature difference is calculated according to the temperature change curve, and if the relative temperature difference is larger than the preset temperature threshold value, it is accurately and comprehensively judged that the temperature change of the substation equipment is abnormal and the substation equipment may have a fault threat, and abnormal information is output so that related personnel can receive the abnormal information and take corresponding protection measures, and accidents are reduced.

Description

technical field [0001] The invention relates to the technical field of substation monitoring, in particular to a temperature detection method, system and storage medium based on substation equipment. Background technique [0002] There are a large number of substation equipment in the substation. Since there are many substation equipment in the machine room and the heat generation is large, the temperature of the substation equipment is likely to be too high. If the temperature of substation equipment is too high, it may not only cause hardware damage, but also cause software failure due to hardware damage. [0003] In related technologies, the substation equipment in the substation mainly uses temperature sensors to obtain temperature values. To fully monitor the substation equipment, multiple temperature sensors need to be installed, but this will increase the cost of temperature monitoring. If only a few temperature sensors are installed, then only Monitoring the tempera...

AI Technical Summary

Problems solved by technology

[0002] There are a large number of substation equipment in the substation. Since there are many substation equipment in the computer room and the heat is large, the temperature of the substation equipment is likely to be too high.

If the temperature of the substation equipment is too high, it may not only cause hardware damage, but also cause software failure due to hardware damage

[0003] In related technologies, the substation equipment in the substation mainly uses temperature sensors to obtain temperature values. To fully monitor the substation equipment, multiple temperature sensors need to be installed, but this will increase the cost of temperature monitoring. If only a few temperature sensors are installed, then only Monitoring the temperature at a single point cannot accurately express the temperature value of the substation equipment, so the accuracy of temperature monitoring is low
