基于图像识别技术的高压电缆附件数字化工艺库设计与研究

Design and Research of Digital Process Library of HV Cable Accessories Based on Image Recognition Technology

为了实现高压电缆附件安装工艺的标准化管控,确保高压电缆安全稳定运行,技术人员应在项目施工前审核附件安装工艺图纸,减少因施工安装不当而出现的高压电缆线路跳闸事故。为了实现施工中所用图纸与标准图纸信息快速、精准比对,建立了涵盖不同厂家、型号、电压等级高压电缆的数字化工艺库,开发了具有图像识别技术、光学字符识别(OCR)和一致性检测算法功能的指纹识别系统,技术人员在工程审查时可通过指纹识别系统对施工过程中的图纸进行审查,快速准确地定位图纸中的差异信息,排除施工安装过程中形成的高压电缆安全隐患。

In order to realize the standardized control of the installation process of high-voltage cable accessories and ensure the safe and stable operation of HV cables,technicians should review the installation process drawings of accessories before the project construction to reduce the trip accidents of high-voltage cable lines caused by improper construction and installation.In order to achieve rapid and accurate comparison of information between drawings used in construction and standard drawings,a digital process library covering HV cables of different manufacturers,models and voltage levels has been established,and a fingerprint identification system with image recognition technology,optical character recognition(OCR)and consistency detection algorithm has been developed.During the engineering review,technical personnel can review the drawings in the construction process through the fingerprint identification system,quickly and accurately locate the difference information in the drawings,and eliminate the HV cable safety hazards formed in the construction and installation process.
