Automatic checking method for protection pressing plates

Abstract

The invention discloses an automatic checking method for protection pressing plates. According to the method, a mobile phone client obtains a constant-value unique identifier of a screen cabinet wherepressing plates are located, a row number and a column number of the pressing plates are obtained to generate a recognition frame for sampled images, a mobile phone camera is used for shooting and sampling the pressing plates, sampled images are uploaded to a cloud server, the cloud server carries out image recognition and a current pressing plate state is returned to the mobile phone client; themobile phone client automatically matches and checks the current pressing plate state with a pre-obtained terminal standard pressing plate state to judge the consistency therebetween; and an analysisreport is generated, and if the current pressing plate state is not matched with the terminal standard pressing plate state, marking and automatic alarm are carried out. The method is capable of solving the manual checking difficulty of pressing plates, rapidly and effectively checking states of the pressing plates, effectively shortening the pressing plate checking time of substation watchers, improving the pressing plate checking correctness and effectively improving the safety level of power grids at the same time.

Description

technical field [0001] The invention belongs to the technical field of power system equipment detection, and in particular relates to an automatic checking method for a protective pressure plate. Background technique [0002] The protection pressure plate includes a function pressure plate and an outlet pressure plate. The function pressure plate is used for switching on and off of some protection functions, and the outlet pressure plate is used for the tripping of the circuit breaker or the start of other protection functions. When the operation mode is changed, it often involves switching on and off of the protection pressure plate. If there is a missing or wrong switching, it will directly affect the realization of the protection function. In serious cases, it will cause the protection to refuse to operate or malfunction, resulting in a large-scale power outage. Therefore, every month the on-duty staff will check the correctness of all the pressure plates in the whole sta...
