Embodiment Construction

[0050] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0051] Such as figure 1 As shown, the present invention provides an image recognition system for the opening and closing state of the start-up drag switch of a power station, including a video sensor, an image preprocessing module and a comprehensive judgment module, wherein the video sensor is directly installed on the shell of the start-up drag switch, and the video The sensor acquires the real-time image data of the switch, the image preprocessing module receives the real-time image data and preprocesses the acquired image data, the preprocessed image data is transmitted to the comprehensive judgment module, and the comprehensive judgment module calculates the image data, and finally the calculated The image data and the initial state of the switch are combined to obtain the final opening and closing state of the switch.

[0052] In this em...

Abstract

The invention discloses a power station starting dragging switch opening and closing state image identification method and system. The method comprises the following steps: acquiring and receiving image data; positioning a switch-on sensitive area on the image data, performing image processing on the switch-on sensitive area, and taking a support plate on a crank arm as a switch-on in-place key auxiliary feature to obtain a switch-on in-place judgment result; positioning a double-opening sensitive area on the image data, carrying out image processing on the double-opening sensitive area, and obtaining an opening in-place judgment result by taking the edge of the moving contact and the supporting plate on the crank arm as the key auxiliary characteristics of opening in place in sequence; and the closing in-place judgment result and the opening in-place judgment result are combined with the initial state of the starting dragging switch to obtain the opening and closing state after the action of the starting dragging switch, and image recognition is completed. Only sensitive area parameters need to be configured in the initial stage of use, online use can be achieved, time is saved, and cost is low.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to an image recognition method and system for opening and closing states of a power station start-up drag switch. Background technique [0002] At present, there is an increasing demand for intelligent monitoring of generator circuit breaker systems in power stations. For the information collection of the opening and closing status of the internal conductors of the start-up drag switch and the start-up of the bus section isolating switch, manual observation is basically adopted. The staff go to the side of the primary equipment and pass through the observation window on the switch casing to check and judge its opening and closing position with naked eyes. This method consumes manpower, is inefficient, has a large workload, is not safe, is inconvenient to observe, and is prone to errors. In this regard, remote video monitoring technology urgently needs to be popularized and...
