Overheat judgment system for lead connecting pipe of power transmission line

The invention relates to a power transmission line wire connecting pipe overheating judgment system, and the system comprises an inspection execution device which is used for starting night inspection operation based on infrared image collection for a power transmission tower at night; the pipe body distinguishing mechanism is used for identifying a sub-picture where each wire connecting pipe is located in the infrared inspection picture subjected to targeted quality improvement processing; and the overheating judgment mechanism is used for determining whether the wire connecting pipe is in a pipe body overheating state or not based on the red component numerical value of each constituent pixel point of the sub-picture where the wire connecting pipe is located. The overheat judgment system for the wire connecting pipe of the power transmission line is compact in structure, convenient and practical. A night infrared inspection mechanism can be introduced to execute an overheat detection mechanism based on visu
