A method and system for optimizing power line inspection trajectory

Abstract

The invention discloses a method and a system for optimizing a trajectory of a power line patrol inspection, including: step 1, constraining the trajectory points collected by the patrol inspection into an inner buffer zone and an outer buffer zone, and obtaining a first trajectory point set and a second trajectory point set; step 2, perform mean value processing on the second track point set, and obtain the third track point set; step 3, perform topology constraints on the first track point set and the third track point set, to eliminate redundant track points and repeated tracks points and abnormal trajectory points; step 4, sort the remaining trajectory points in the first trajectory point set and the third trajectory point set in time order. The invention is used to optimize the inspection track data collected by the mobile inspection equipment, so as to reduce redundant data and error data and make the inspection track more concise and reasonable.

Description

technical field [0001] The invention belongs to the technical field of power line patrol inspection, and in particular relates to a method and system for optimizing a power line patrol inspection track. Background technique [0002] At present, the inspection operation of power lines is a routine operation content of line maintenance. The paper-based operation method used in traditional inspection is relatively backward, and the operation method with the help of mobile inspection equipment and corresponding inspection auxiliary software has been adopted by many maintenance units. However, due to the uncertainty of the direction of the power line, especially the hidden parts of some equipment, the inspection operation is still not efficient enough. [0003] Relying on the positioning function of the high-precision GPS module, the problems of equipment positioning and inspection trajectory collection are well solved. On the one hand, the inspection track collection is conduc...

AI Technical Summary

Problems solved by technology

However, since the frequency of collecting the inspection trajectory by the mobile inspection equipment cannot be too low, there are many discrete trajectory points collected by the inspection trajectory.

At the same time, due to the fact that there may be round-trips and detours during the actual inspection operation, coupled with abnormal points caused by weak signals, etc., there are a large number of redundant or wrong data in the inspection track, which guides the value of subsequent inspection operations also greatly reduced
