Abstract

The invention discloses a method for automatically identifying a terminal connection state by using a terminal strip picture in a relay protection screen cabinet. The method comprises the following steps: acquiring a screen cabinet terminal strip picture in a transformer substation; carrying out region division on the basis of the preprocessed photo, numbering terminal strips in each region and labeling terminal connection states to form a training data set with labels; training the data set based on a yolov5 neural network to generate a terminal identification model, and identifying the newly obtained picture of the terminal strip of the screen cabinet in the transformer substation to obtain a terminal strip number area and a terminal connection state; and performing picture character recognition to form a recognition result of the association relationship between the terminal strip number and the terminal connection state, and automatically comparing the recognition result with a screen cabinet terminal strip reference value to generate a terminal strip checking record. In the embodiment of the invention, the terminal strip connection state, the terminal strip number and the association relationship thereof are automatically identified by using the relay protection screen cabinet terminal strip picture shot by the mobile terminal, and the safety check of the terminal strip in the protection screen in the relay protection operation is quickly realized.

Description

technical field [0001] The present application relates to the technical field, in particular to a method for automatically identifying terminal connection status from a picture of a terminal row in a relay protection panel cabinet. Background technique [0002] In the prior art, the status of the terminals in the relay protection panel cabinet directly affects the operation of the relay equipment, and the position of the terminals themselves may be centered on the end and distributed at different angles, which is what makes the staff check The overall workload is very large. If image collection is used, how can we target the terminals of the screen cabinets in the station considering the number of terminals? Contents of the invention [0003] In order to solve the above-mentioned technical problems, the embodiment of the present application provides a method for automatically identifying the connection state of the terminals from the picture of the terminal row in the rela...
