Control method and control device for preventing misoperation of protective pressure plate

Abstract

The embodiment of the invention discloses a control method and a control device for protecting a pressing plate against misoperation. The control method for preventing misoperation of the protective pressure plate includes collecting and outputting the operation task code and the identity information of the operator by the information collection device; the controller verifies the identity information; The mapping relationship between the operation task and the operating state determines the target operating state of the protective platen; the controller determines the target operating area based on the target operating state and the preset mapping relationship between the platen number and the platen area; the sensor device collects and outputs the finger position of the operator ; The controller judges whether the current operation is legal based on the comparison result between the finger position and the target operation area. By judging whether the operator's operation is legal in advance before the operator operates the protective pressure plate, and giving corresponding prompts when the current operation is judged to be illegal, so as to avoid safety risks caused by misoperation.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electrical equipment operation and maintenance, and in particular to a control method and control device for protecting a pressure plate against misoperation. Background technique [0002] The correct input and withdrawal of the inner pressure plate of the relay protection panel in the substation is related to the normal operation of the protection device. Therefore, how to ensure the correctness of the operation is very important. [0003] Existing technical solutions can mainly be classified into two categories. One is to use image recognition technology or add auxiliary signal contacts on the pressure plate to collect corresponding images or signals, and then identify the state of the protection pressure plate, and compare it with the preset state of the pressure plate to know whether the operation of the protection pressure plate is correct , which means that if there is a m...

Problems solved by technology

This type of method requires each protective plate to be equipped with auxiliary devices such as a protective cover or a reminder light. The wiring is more complicated, the maintenance of the device is large, and the operation steps are more cumbersome.
