in the first step, normally, the normally-closed gate 4 is in normally-closed state, the normally-open gate 5 is in normally-open state, and the normally-closed gate 4 blocks the passage of pedestrians.
Step two, when the pedestrian needs to pass through the door frame 1, the pedestrian needs to pass through a channel between the main machine boxes 2, the pedestrian inputs identity information through the identity recognition module 3 and sends signals to the identity information verification module, and the identity information verification module reads information stored in the database and compares the information with the sent information recognized by the identity recognition module.
And step three, when the comparison fails, the identity information verification module sends information to the controller, the controller sends a signal to the warning module after receiving the signal, and the warning module sends warning to pedestrians to prompt identity information verification errors.
And step four, when the comparison is passed, the identity information verification module sends a signal to the controller, the controller receives the signal and then sends the signal to the normally closed gate 4, and the normally closed gate 4 is opened after receiving the signal, so that a channel between the main cases 2 is opened for pedestrians to pass.
