Abstract

A thermal infrared image processing method and system for wire temperature monitoring, comprising the following steps: 1) collecting multiple infrared thermal image images of different wires in a power distribution cabinet at fixed points, storing and preprocessing; 2) using a machine for infrared thermal image images The learning algorithm performs image processing, and then identifies the conductor area and its temperature in each picture; 3) Repeat steps 1) and 2), and splicing the identified images to obtain all the conductors and their corresponding temperature maps of the power distribution cabinet. The invention realizes real-time update and storage of the temperature data of each wire, improves the accuracy of temperature monitoring, and effectively avoids thermal abnormality of the wire due to temperature rise.

Description

technical field [0001] The invention relates to the field of power distribution cabinets, in particular to a thermal infrared image processing method and system for wire temperature monitoring. Background technique [0002] Electric power resources are the necessary energy resources for activities such as production and life in all fields of our society, and are closely related to the production and life of the people.
