One Edge Detectable Algorithm Which Suits The High Voltage Switch

With the development of the Power industry and especially the highest pressure nets raises to set up actively, the safety of the Power system to automation, the intelligence turn of the request is more and more high, the Power television system to put forward and applies provide a powerful technique foundation to the transformer substation, which are a beneficial complement of the function to the traditional"four movements". But in the actual movement of the Power television system, the picture of the television video flows being displayed in the supervising and controlling port didn't through any processing of the video original picture, this to some blurry video or night video picture bring a very huge difficulty when judge the equipments appearance. Therefore, it's important to carry on research to the technique of the Power television system video picture because this is valuable to the engineering and academic.This paper first introduced the basic knowledge of the Power television system about the video, and after described and discussed some related technique knowledge about the video picture processing, then take the switch which is in the video picture as an example, bring forward a kind of being applicable to the switch in the video picture of the edge detection, and respectively to the switch of the GW17-550D that appears close situation and the switch of GW22-12 that appears open situation adopt classic detection way and the paper's detection way carried on MATLAB simulation, the result expresses that the paper'detection way had great superiority. Finally to the video picture move carried on analysis and put forward some solutions, including the two parts of making sure the location of starting point and revising the changed relative coordinates, among them, it gives actually simulation example to make sure the location of starting point, and explains the principle of the way to revise the changed relative coordinates, then, this paper carried on complement modification to the paper's detection way's flow chart, make it more meet actual demand.The end this paper carried on summary to the work that this paper makes, and points out the advantage and shortage of this paper's edge detection way, and gives an prospect to the later research direction.
