Pressing plate state image identification method and system

Abstract

The invention provides a pressing plate state image identification method and system, which can be used for verifying an operation result when operation and maintenance personnel execute pressing plate switching operation on a transformer substation screen cabinet according to an electronic operation ticket, and the identification method comprises the following steps: identifying the current state of each pressing plate of the screen cabinet after the pressing plate switching operation by using a mobile terminal APP; employing the mobile terminal APP for identifying and reading a label at the screen cabinet of the transformer substation, and querying the pressing plate switching target state of the screen cabinet after the pressing plate switching operation from the pressing plate account management module according to the identification and reading result of the label; after one step or multiple steps of pressing plate switching operation are executed according to the electronic operation ticket, performing operation result verification on the identified current state of the pressing plate according to the queried pressing plate switching target state in the method, and when the pressing plate state recognition result is not consistent with the pressing plate switching target state, stopping the pressing plate subsequent operation in the electronic operation ticket. According to the invention, the efficiency and accuracy of pressure plate state checking can be improved, and the workload and difficulty of pressure plate state checking and pressure plate inspection can be reduced.

Description

technical field [0001] The invention relates to the technical field of power grid operation and maintenance, in particular to an image recognition method and system for a pressing plate state. Background technique [0002] In the substation's platen inspection, operation and maintenance routine switching and checking the correctness of the platen throwing and withdrawing during the maintenance operation process is the key work of the daily operation and maintenance. In order to meet the normal state of the platen throwing and withdrawing, the platen is generally put into operation on a monthly, quarterly and operational basis. Retirement status check, which puts high demands on the work efficiency and quality of operation and maintenance personnel. [0003] The target of the pressure plate status check is the pressure plate on each protective device screen cabinet of the substation. A 220kV conventional substation generally has 50~80 screen cabinets, and each screen cabinet ...

Problems solved by technology

[0005] During the process of checking the status of platen throw-in and withdrawal, there are many screen cabinets, a large number of platens, and a high frequency of operations. It is easy for operation and maintenance personnel to make subjective judgments on whether the platen throw-in and withdrawal is correct;

When checking the switch-in and withdrawal status of the pressure plate, each screen cabinet and the pressure plate on the site are basically the same, and there is no obvious sign to indicate whether the pressure plate of the screen cabinet should be cast or withdrawn, and the operator is likely to miss or wrongly inspect the pressure plate of the screen cabinet;

The pressure plate generally does not have a mandatory locking device to lock and prohibit the operation of throwing and withdrawing. When the door of the screen cabinet is opened, the throwing and withdrawing operation can be performed at will, and there is a risk of mistakenly throwing, mistakenly returning, missing, throwing and returning the pressure plate.
