【摘要】：目前,我国大力发展智能变电站,构建大数据平台。在这战略背景下,电力设备的状态检测与诊断是智能变电站非常重要的一环,目前已被纳入到智能变电站建设中,而由于红外检测是电力设备检测的重要手段,因此,热像仪自然成为了电力设备状态检测中的重要工具。本文通过分析当前热像仪检测技术在电力检测的应用现状,发现存在数据离散、对电力设备的诊断比较粗糙等问题。在深入了解电力系统的需求状况,熟悉检测业务流程的基础上,本文利用热像仪、图像处理、软件工程等技术,设计开发适用于电力设备的精细化分析系统。本系统包括红外检测前端设备、3G网络、服务器以及客户端。红外检测前端设备采集数据,并通过3G网络实现其与服务器、客户端之间的通信与数据传输。服务器实现数据库操作、数据存储、数据分析以及权限管理。客户端实现预置位与设备台帐的匹配,以及对红外检测前端设备的控制、巡检路线的设置以及热图的分析等功能。为达到精细化分析的目标,客户端的开发包括对热图的点、线、方框、圆、椭圆、多边形、轮廓等区域温度分析工具的设计,以及电力设备的分析规则与报警功能设计。本系统以SQLSever2012作为数据库平台,采用VS2012进行软件设计,采用OpenCV开源视觉库对图像分析处理,完成基于红外图像分析的电力设备精细化分析软件设计,实现对电力设备采集红外图像并进行精细化测温分析的目的。运行测试结果表明,本系统所设计的软、硬件各项功能能可靠、稳定工作,实现了对电力设备的测温分析功能以及规则分析功能,完成了本系统对电力设备精细化分析的目标,对于提升电力设备的在线检测业务精细化水平有积极而深远的意义。
[Abstract]:At present, our country vigorously develops the intelligent substation, constructs the big data platform, under this strategic background, the electric power equipment condition detection and the diagnosis is the intelligence substation very important link. At present, it has been incorporated into the construction of intelligent substation, and because infrared detection is an important means of power equipment detection, so. Thermal imager has naturally become an important tool in the state detection of power equipment. This paper analyzes the current application of thermal imaging technology in electric power detection and finds that there are discrete data. The diagnosis of power equipment is rough. On the basis of deep understanding of the power system requirements and familiar with the detection business process, this paper makes use of thermal imager, image processing, software engineering and other technologies. The design and development of a detailed analysis system for power equipment. This system includes infrared front-end equipment 3G network, server and client. Infrared front-end equipment to collect data. The communication and data transmission between the server and the client are realized through 3G network. The server realizes database operation and data storage. Data analysis and authority management. The client realizes the matching of the preset and the equipment account, and the control of the front end equipment of infrared detection. In order to achieve the goal of fine analysis, the development of client includes the point, line, box, circle, ellipse, polygon of thermal map. The design of area temperature analysis tools such as contour, as well as the analysis rules of power equipment and the design of alarm function. This system takes SQLSever2012 as the database platform. The software is designed with VS2012, and the image is analyzed and processed by OpenCV open source vision library. The detailed analysis software of power equipment based on infrared image analysis is designed. The purpose of collecting infrared image and analyzing the temperature of power equipment is realized. The test results show that the software and hardware of the system can work reliably and stably. The function of temperature measurement and analysis of power equipment and the function of rule analysis are realized, and the goal of fine analysis of power equipment in this system is accomplished. It has a positive and profound significance for improving the fine level of online detection service of electric power equipment.
