Substation perimeter laser fence position correction system and method based on image capture

Abstract

The invention relates to a substation perimeter laser fence position correction system and method based on image capture. The position correction system comprises control devices, three-dimensional holders, diode verification devices and image capture devices, wherein the three-dimensional holders, the diode verification devices and the image capture devices are connected with the control devicesrespectively. Each diode verification device comprises a laser diode and a photosensitive sensor, wherein the laser diode and the photosensitive sensor are arranged on two adjacent fence vertical rodsrespectively. Each image capture device comprises a camera and a reference object with point light sources. The cameras are arranged on the fence vertical rods. The reference objects with point lightsources are fixedly arranged at positions 30 cm from the vertical rods. The three-dimensional holders match the fence vertical rods. The fence vertical rods are vertically arranged on the three-dimensional holders. The control devices control the movement of the three-dimensional holders according to the feedback results of the diode verification devices and the image capture devices to correct the position of the fence vertical rods. Compared with the prior art, the system provided by the invention has the advantages of high correction efficiency, timely correction and the like.

Description

Technical field [0001] The invention relates to the technical field of substation perimeter protection, and relates to a substation perimeter laser fence, in particular to a system and method for correcting the position of the substation perimeter laser fence based on image capture. Background technique [0002] At present, a large number of laser fences are used in the safety monitoring of substations, which are necessary devices to prevent foreign objects from intruding and protecting equipment. However, even if the existing fence adopts a retractable fence bracket fixed on the work site, long-term outdoor operation will cause positional deviation due to factors such as deformation of the base, water accumulation in the device, and unstable expansion and contraction, resulting in the acceptance of laser fences. If the other party's signal is not available, an error alarm is generated. The traditional laser fence position correction is done by manual means, the work efficiency ...

AI Technical Summary

Problems solved by technology

However, even if the existing fence adopts the retractable fence bracket fixed on the job site, the long-term outdoor operation will cause the position to shift due to factors such as base deformation, water accumulation in the device, and expansion and contraction instability. The other party's signal is not received, and a false alarm is generated

The traditional laser fence position correction is done by manual means, the work efficiency is low, and the offset correction cannot be performed in time
