AI Technical Summary

Technical Problem

In the existing distribution network operating status monitoring system, slipping is prone to occur between the track and the roller, which affects the movement positioning accuracy and thus affects the efficiency of image recognition and acquisition.

Method used

A distribution network operating status monitoring system is designed, and laser ranging sensors are used to cooperate with positioning plate components to achieve accurate positioning between the camera and the distribution cabinet. The real-time distance value is obtained through the laser ranging sensor, and the speed and movement of the walking mechanism along the rail are controlled to ensure the accurate correspondence between the camera and the distribution cabinet. At the same time, the lifting mechanism can adjust the height of the camera to adapt to image acquisition of different heights.

Benefits of technology

It improves the mobile positioning accuracy, ensures the accurate correspondence between the camera and the distribution cabinet, improves the efficiency of image acquisition and recognition, and achieves the purpose of automatic inspection.

Abstract

The invention provides a power distribution network operation state monitoring system, which comprises a track, the track is provided with an along-track walking mechanism, the bottom of the along-track walking mechanism is provided with a lifting mechanism, and the bottom end of the lifting mechanism is provided with a camera; a walking positioning mechanism is arranged on the along-rail walking mechanism and provided with a vertical rod vertically and fixedly arranged at the top of the along-rail walking mechanism, a laser distance measuring sensor is vertically and fixedly arranged on the side face of the top end of the vertical rod, and positioning plate assemblies matched with the laser distance measuring sensor are arranged at the positions, corresponding to the power distribution cabinets, of the rail. A steering engine for driving the positioning plate assembly to swing up and down in a reciprocating manner is arranged on the track; through cooperation between the laser distance measuring sensors and the positioning plate assemblies, precise positioning between the camera and the power distribution cabinet can be achieved, meanwhile, the real-time distance value between the laser distance measuring sensors and the corresponding positioning plate assemblies is obtained through the laser distance measuring sensors, speed reduction is conducted in advance when the camera approaches the target position, and the situation that the positioning precision is affected due to the too high speed is avoided.
