Embodiment Construction

[0032] The structural feature of the knife switch that rotates and closes in the vertical plane is that it contains a base, or a fixed end, and a knife arm with a joint in the middle and hinged to the base. In the straight plane, the obvious feature of the joint part is that its side projection is a disc-shaped structure, which is relatively easy to identify, while on the base side, it is easier to identify as a rounded rectangle, and the long side is parallel to the knife gate The form of the arm in the state of opening and closing, that is, the horizontal state.

[0033] In order to reduce manpower consumption or the inconvenient installation of fixed optical acquisition equipment, this solution is based on the mobile robot, by analyzing the visible light or infrared images collected by the mobile robot, using image pattern recognition technology, by analyzing the distance between the feature point of the knife arm and the fixed end , to realize the automatic identification ...

Abstract

The invention discloses a knife switch closing reliability judging method based on the distance between a knife switch arm feature point and a fixing end, which is applied to knife switches rotating in vertical surfaces to be opened and closed and includes the following steps of: A, module information generating, B, preprocessing after real-time image collection, and C, opening and closing in place judging through comparison of elements with state not changing or changing a little during image collection. The knife switch closing reliability distinguishing method based on the distance betweenthe knife switch arm feature point and the fixing end effectively solves the problem of automatic judging of the knife switch closing reliability.

Description

technical field [0001] The invention relates to a method for judging the reliability of a switch closing position based on the distance between a feature point of a switch arm and a fixed end. Background technique [0002] In the operation of substation, the knife switch is an important equipment for changing the operation mode. The "Technical Regulations of the Electric Power Industry" specially configures a set of operation precautions for the knife switch. During the operation of the switch in the substation, due to the abnormality of the limit switch of the secondary circuit of the switch or the looseness or stagnation of the mechanical components of the primary part of the switch, it will cause unreliable opening and closing of the switch, which will directly affect the safety of the system power supply and reliability, and may even cause vicious accidents, which will inevitably affect industrial and agricultural production and people's normal life, and bring losses to ...
