7. The platen status image recognition system of claim 5, wherein: the pressing plate image recognition AI algorithm is based on a neural network, and the training of the neural network comprises the following steps;
step A1, taking pictures of the pressing plate under various light rays and angles by different personnel to collect training samples; the acquisition amount of the training samples is that each kind of pressing plate is not less than 20 matrix images, and the divided and closed states of the pressing plates respectively account for 40-60%;
a2, carrying out accurate sample labeling on the collected training samples through sample labeling software;
a3, generating a training set and a test set according to the sample, wherein the training set is used for training the neural network, and the test set is used for testing the recognition rate of the neural network; training of the neural network is performed with a dark neural network learning framework using a computing device with GPU acceleration;
step A4, in the training process of the neural network, optimizing by parameter adjustment, namely verifying the network generated by training by using a test set after the training of the neural network is finished, and continuously adjusting and optimizing according to the test result to generate the neural network meeting the requirements; and obtaining a neural network recognition engine model including the weight file.
8. The platen status image recognition system of claim 5, wherein: when the identification system is used for inspecting the pressing plate, the pressing plate image acquisition and analysis module judges whether the screen cabinet is an inspection target according to the identified screen cabinet two-dimensional code, and then quickly and automatically checks and checks the pressing plate throwing and withdrawing correctness of each screen cabinet according to the pressing plate account data record, and prompts a pressing plate state identification result.
9. The platen status image recognition system of claim 5, wherein: the mobile terminal is provided with an electronic ticket APP; the electronic ticket APP is connected with an anti-misoperation cloud module of the transformer substation anti-misoperation system through a wireless network to obtain an electronic operation ticket; the anti-misoperation cloud module comprises a pressing plate standing book management module.
