Embodiment Construction

[0031] In the following description, many technical details are proposed in order to enable readers to better understand the application. However, those skilled in the art can understand that without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can be realized.

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0033] The technical solution of the present invention utilizes the strategy of dividing the whole into parts and the image comparison technology to confirm the closed state of the knife gate, and the specific shape of the knife gate basically does not increase the difficulty of the judgment process. At the same time, the technical solution is eas...

Abstract

The invention relates to the field of image identification and discloses a method and a system for determining turning-on or turning-off of a switch. The method comprises the following steps of: acquiring images from a plurality of characteristic regions; performing edge extraction, and solving edge gradient histogram data; judging whether the edge gradient histogram data is matched with sample data; and determining the turning-on or turning-off of the switch according to the number of the matched characteristic regions. The invention has the advantages that: a judgment result is accurate and more stable; by using the turning-off state of the switch as a comparison reference, a stable and accurate comparison result is easier to obtain; and the characteristic regions are rectangular frames with simple background preferably and comprise the straight-line characteristics of the switch.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a technology for judging whether a knife switch is opened or closed by using image recognition. Background technique [0002] In the substation, the switching on and off of the high current circuit is controlled by a knife switch. In some scenarios, such as when a power failure occurs or a routine inspection occurs, it is necessary to know whether the switch is in a closed state or an open state. [0003] At present, the method of judging whether the knife switch is opened or closed is to send people to the scene to observe with the naked eye. However, the substation may be far away from the permanent location of the staff, and manual observation on site is time-consuming and laborious, which is very inconvenient. Moreover, the number of substations is large and the distribution is wide. If it is necessary to know the switch status of multiple substations at the same time, a lo...
