Problems solved by technology

With the increasing number of distribution network equipment, traditional manual inspections face the following problems: First, the ratio of equipment to labor is huge, and the efficiency of manual inspections is low, which cannot meet the requirements of periodic inspections; second, the accuracy of manual temperature measurement and partial discharge measurement is poor. , the requirements for the experience and skills of the inspection personnel are high; the third is that the records and archives of the inspection results are cumbersome, and the efficiency of manual entry is low; the fourth is that the traceability of historical data is poor
At this time, the on-board system cannot determine whether the detected ultrasonic signal comes from the power distribution line, and the human-computer interaction device can only display the acquired ultrasonic signal. As for where the ultrasonic signal comes from, there is no intuitive way to visualize it if only ultrasonic equipment is used. show signal source
If a visible light camera is simply added, due to mechanical interference, the axis where it is located must not be collinear with the axis of the ultrasound equipment at the same time to collect pictures at the source of the ultrasound receiving signal
Assume that the target is about 10m away from the vehicle during the normal inspection of the vehicle. For general detection equipment, this distance is relatively long. If there is an angle error of even 1 degree, the resulting error will reach 175mm. This error is twice the size of the ultrasonic caliber. times, based on the problem of long-distance error amplification, the improvement of manufacturing precision cannot solve this problem

Abstract

The invention provides a visual positioning device and a positioning method for discharge point of power distribution equipment; whereinthe device comprises an ultrasonic detection mechanism and a visible light shooting mechanism which are fixed on a rotating holder, and the ultrasonic detection mechanism and the visible light shooting mechanism are coaxially and reversely arranged. The positioning method comprises the steps that a motor of the rotating holder receives a control instruction of a control terminal; the rotary holder drives the ultrasonic detection mechanism to rotate, and the ultrasonic detection mechanism performs detection according to a received control instruction of the control terminal; when the ultrasonic detection mechanism detects an abnormal signal, the rotary holder rotates by 180 degrees from the abnormal signal position, so that the visible light shooting mechanism directly faces the abnormal signal position; and the visible light shooting mechanism shoots an abnormal signal position according to a control instruction of the control terminal. According to the invention, the ultrasonic detection of the power distribution equipment in the coaxial mode and the visualization function of the corresponding point location are realized, and the visualization precision of the discharge point location is improved.
