Abstract: At present, the verification of substation pressure plates requires manual on-site verification, which lacks work efficiency, flexibility, and accuracy. In order to solve the problems of time-consuming, low work efficiency, and high error rate in verification, we provide a support technology for the verification of pressure plates through the technology of image recognition algorithms. We build a substation pressure plate database system and use a portable pressure plate verification handheld platform, which is of great significance for improving the current manual paper form verification method and solving the problem.
