Embodiment

[0024] Example--hard platen check

[0025] (1) Build a hard platen model

[0026] The hard platen model includes screen cabinet information, protection equipment information in the screen cabinet, platen name, platen position information, platen status information, platen function attributes, and the relationship between platen and equipment.

[0027] (2) Platen image acquisition

[0028] When the smart mobile terminal collects inspection data, the inspection of the item [Protective pressure plate (including soft pressure plate) input meets the requirements] triggers the mobile terminal to collect the image of the pressure plate of the screen cabinet, and transmits the image to the pressure plate identification module of the operation and maintenance system.

[0029] (3) Recognition and verification of platen status

[0030] The operation and maintenance system workstation recognizes the received platen images one by one, compares and checks the recognition results with the ...

Abstract

The invention discloses an automatic verification method for relay protection, which is based on the intelligent identification technology, according to the standardized operation requirements of substation relay protection, a one-key protection constant value is obtained from a relay protection device, by collecting a protection screen cabinet pressing plate picture and constant value value dataand adopting the image identification and machine learning technology, the intelligent identification and automatic judgment of a relay protection screen cabinet pressing plate and the mapping of theconstant value of the relay protection device, detection procedures are intelligently generated, therefore automatic verification of the protection function is achieved through a relay protection tester, and a verification report is automatically generated. Moreover, through the standardized regular checkup operation of a portable intelligent mobile terminal, paper-free regular checkup work is realized, the workflow and items are standardized, the data records are electronized, and the correctness and reliability of regular checkup operation data are ensured.

Description

technical field [0001] The invention relates to the field of relay protection verification, in particular to an automatic verification method for relay protection. Background technique [0002] The annual calibration of relay protection is a common business in the daily work of electric power production. The periodic calibration tasks are heavy, and the personnel devote a lot of energy to repetitive tasks such as the preparation of work instructions, test data recording, sorting, and input.
