The invention discloses a substation pointer type knife switch action degree identification method and device, and aims to solve the problems that the action degree of a knife switch in a corresponding state cannot be accurately identified at present, manpower and material resources are consumed by manual identification, and good management of a substation is not facilitated. The method comprisesthe steps of collecting a to-be-identified knife switch image; determining a specified character position, a graduated scale position and an indicator position in the to-be-identified knife switch image according to a pre-trained target detection model; determining the on-off state of the knife switch in the knife switch image to be identified according to the relationship among the specified character position, the graduated scale position and the indicator position; and determining the action degree of the knife switch in the corresponding state according to the relationship between the position of the indicator and the starting point and the ending point of the corresponding graduated scale.
Description
technical field [0001] The present application relates to the technical field of switch state identification, and in particular to a method and device for identifying the action degree of a pointer type switch in a substation. Background technique [0002] In the substation, the knife switch has the functions of overcurrent protection, switching control, emergency braking, etc., and is a very important power equipment. Therefore, it is very necessary to accurately identify the opening and closing state of the knife switch and grasp the state of the knife switch at all times. [0003] At present, the methods for identifying the opening and closing state of the pointer knife switch include: manually confirming through the video monitoring screen, or by collecting the image of the knife switch to be identified and performing image recognition to judge the opening and closing state of the knife switch. [0004] However, the opening and closing state of the knife switch is not o...
