Image Recognition Of Electric Device On/Off State Based On Remote Vision

Vision is the important means of observing and cognizing the world for human being. Following the improvement of power system automation and management modernization,power remote vision(Remote video monitoring) and the technology of infrared heat imaging are applied to power system widely. It supplies abundant local information for power system. from which not only power system operators can realize the state of local equipments and environment straightly and accurately,but also by analyzing these images,we can solve many difficult question of power system. Because of the property of duration, real time, complexity, strong coupling of power system process, the images of remote vision and infrared heat imaging are too abundant to monitor and analyze for human being. This article brings up the directions for the questions. Firstly, the framework, functions and key technology of network remote vision are expatiated. Following the integration of remote vision and technology of infrared heat imaging is introduced, the software and hardware integration of remote vision and infrared heat imaging, the pretreatment, fake color coding and transmission coding of infrared heat imaging in remote vision is particularly discussed. It discusses several key technology questions. On base of discussion of remote vision and technology of infrared heat imaging integration, it imports machine vision, proceeds with auto-recognition of switch, particularly discusses the state recognition of switch base of remote vision. It discusses the image collection, coding, binarization and depth analysis of switch. It elaborates matching arithmetic of switch state. Discusses the matching difficulty when the state of switch is difficult to confirm. On base of auto-recognition emluator, it analyzes the performance of auto-recognition system. It strikes up the mathematics model of anti-jamming, emulates the factors which affects veracity, reliability and real time. Secondly it dissertates image recognition of relay pressing on/off based on integrated remote vision, researches arithmetic and effects of recognition. It does a deploitation research for advanced apply of integrated remote vision. The researched problems of this article are summed up and more research directions are introduced about integrated remote vision lastly.
