Problems solved by technology

During the opening and closing process, each device needs to cooperate with each other to complete the opening and closing of the switch. If the equipment fails or the coordination is not in place, it will cause the switch cabinet to fail, causing equipment and personnel injury. Therefore, it is very necessary to check the operating status of the switch cabinet. real-time monitoring
[0004] At present, the monitoring of the operating state of the switchgear mainly relies on various electrical sensors, which rely on monitoring various electrical signals to indirectly determine the working state of the switchgear, and the amount of monitored states is small and the visibility is poor.

Abstract

The invention discloses a switchgear operating state management monitoring system, method and computing equipment, including ground knife status, handcart position and arc monitoring; The knife image recognizes the current position of the ground knife, and determines whether the ground knife is currently in the opening state or the closing state; in the handcart position monitoring, the handcart image currently collected by the second image acquisition device is used to identify the position of the handcart. Position, to determine whether the handcart is currently moving to the opening or closing state. In the arc light monitoring, there is no contact image under lighting in the switch cabinet currently collected by the third image acquisition device and the third image acquisition device. The comparison results of the gray feature values ​​between the collected contact images where the arc phenomenon occurs can determine whether the arc phenomenon currently occurs; the present invention monitors the operating state of the switch cabinet in real time in a non-contact manner, and can realize the monitoring of the operating state of the switch cabinet. Accurate monitoring.

Description

technical field [0001] The invention belongs to the field of electric power measurement, and in particular relates to a management and monitoring system, method and computing equipment for the operating state of a switchgear.
