Problems solved by technology

Since the GIS equipment is a sealed equipment, the outside cannot directly observe the internal equipment in place, so it can only be reflected indirectly by means of external instructions and operating mechanism signs
[0004] However, there are following problems: the isolating switch and the grounding switch in GIS are sealed inside the equipment, and their opening and closing positions cannot be directly observed visually. Judge according to the travel auxiliary switch of the switch and the transmission indicator
[0007] The inventor believes that when judging the opening and closing state of the isolating switch through the magnetic induction sensor, the micro switch and the position and posture sensor, it needs power-off installation and maintenance, which is inconvenient for maintenance. There is no self-test function, and it is impossible to objectively quantify the degree of opening and closing of the isolating switch, and it is impossible to output abnormal state information

Embodiment 1

[0038] The fish-eye opening and closing indicator, including the housing, is provided with a transparent observation window and an opaque shadow part on the housing, and an indicator plate printed with the words "open" or "close" corresponding to the observation window and shadow part , wherein, there are two observation windows. When the sign on the sign is in the observation window, the fisheye opening and closing is in the closed state. When the sign on the sign is in the observation window, the fisheye opening and closing Gate is open.

[0039] This embodiment discloses a substation fish-eye switch in order to realize the identification of the opening and closing state of the fish-eye switch by collecting the indicator image, and then to identify the opening and closing state of the fish-eye switch, and to realize the quantitative analysis of the switch-off and switch-off degree. Opening and closing state identification methods, such as figure 1 shown, including:

[0040...

Embodiment 2

[0079] In this embodiment, a substation fisheye opening and closing state identification system is disclosed, including:

[0080] The image acquisition module is used to vertically shoot the fisheye opening and closing indicator to obtain the indicator image;

[0081] The image analysis algorithm module is used to analyze the indicator image to determine the position of the two boundary lines of each observation window and the type and position of the characters in the observation window; the intersection of the two boundary lines of the two observation windows is Center of the circle, take the intersection point of the two boundary lines of the two observation windows as the center of the circle, and take the position of the characters in the observation window as the end point to obtain the angle between the line between the center and the end point that deviates from the boundary line of the observation window, and use this angle to identify the separation and combination T...

Embodiment 3

[0083] In this embodiment, a computer-readable storage medium is disclosed, which is used to store computer instructions. When the computer instructions are executed by a processor, a substation fisheye opening and closing state recognition method disclosed in Embodiment 1 is completed. A step of.

Abstract

The invention discloses a transformer substation fisheye type opening and closing state recognition method and system. The method comprises the steps that indicator images are collected in real time; determining positions of two boundary lines of each observation window and types and positions of characters in the observation window according to the obtained indicator image; taking the intersection point of the connecting lines of the two boundary lines of the two observation windows as the circle center, taking the positions of the characters in the observation windows as the terminal points, obtaining the angle of the connecting line of the circle center and the terminal points deviating from the boundary lines of the observation windows, and recognizing the opening and closing states of the opening and closing through the angle. An indicator image is vertically acquired and analyzed, an intersection point of connecting lines of two boundary lines of two observation windows is taken as a circle center, the positions of characters in the observation windows are taken as end points, the connecting lines of the circle center and the end points deviate from the boundary lines of the observation windows by an angle, and the opening and closing state of the opening and closing door is identified through the angle. Quantitative analysis of the opening and closing in-place degree of the opening and closing is realized.

Description

technical field [0001] The present disclosure relates to a method and system for identifying a substation fish-eye opening and closing state. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] GIS equipment is widely used in power systems because of its small footprint and stable performance. Since the GIS equipment is a sealed equipment, the outside cannot directly observe the internal equipment in place, so it can only be reflected indirectly by means of external instructions and operating mechanism signs. [0004] However, there are following problems: the isolating switch and grounding switch in the GIS are sealed inside the equipment, and their opening and closing positions cannot be directly observed visually. Conventionally, they can only be judged based on the travel auxiliary switch of the switch and the transmission indicator. ...
