摘要 通过对不同异物入侵变电站特征的分析,提出了采用基于图像处理技术的变电站防异物入侵技术.基于对图像的帧间差分法原理分析,系统地对两幅或多幅图像差异进行比较,当采集图片与背景图片差异的结果充满一定的面积和变化的位置时,则认为有异物入侵,实现对变电站异物入侵的判断.此外,系统采用了太阳能供电技术和无线4G通信技术,使运行人员能够及时地了解到变电站异物入侵的状态,同时也使整个系统具有现场安装方便等特点.由此可见,整个系统能够实现对变电站异物入侵的准确诊断,具有良好的应用价值. Through the analysis of the characteristics of different foreign bodies invading substation,this paper proposes an anti-foreign body invasion technology for substation based on image processing technology.Based on the analysis of the principle of inter-frame difference method,the system compares the difference between two or more images.When the difference between the collected pictures and the background pictures is full of a certain area and change of position,foreign body invasion is considered to occur,realizing the judgment of foreign body invasion in substation.In addition,the system uses solar power supply technology and wireless 4G communication technology,so that operators can timely understand the state of foreign body intrusion in substations,but also make the whole system easy to install and so on.Therefore,the whole system can realize the accurate diagnosis of foreign body intrusion in substation,and has good application value.
