The working principle of the invention is as follows:
the device realizes the functions of the invention through the following steps, thereby solving the technical problems provided by the invention:
step one, under a normal state, the normally closed gate 4 is in a normally closed state, the normally open gate 5 is normally open, and the normally closed gate 4 blocks the passing of pedestrians.
And step two, when the pedestrian needs to pass through the door frame 1, the pedestrian needs to pass through a passage between the main case 2, the pedestrian inputs identity information through the identity recognition module 3 and sends a signal to the identity information verification module, and the identity information verification module reads information stored in the database and compares the information with the information identified by the identity recognition module.
And step three, when the comparison is not passed, 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 a warning to the pedestrian to prompt that the identity information is verified wrongly.
And step four, when the comparison is passed, the identity information verification module sends a signal to the controller, the controller sends a signal to the normally closed gate 4 after receiving the signal, and the normally closed gate 4 is opened after receiving the signal, so that a channel between the main case 2 is opened for a pedestrian to pass through.
And step five, the monitoring module 6 monitors the passing condition of the pedestrians and sends signals to the controller.
Step six, after the pedestrian passing the identity recognition normally passes through the channel between the main case 2, the controller sends a signal to the normally closed gate 4, and the normally closed gate 4 blocks the channel after receiving the signal.
And step seven, when the power supply is damaged by strong current, the main power supply is disconnected, and the control of the main power supply to the electric control device 7 is removed, so that the internal structure of the electric control device 7 is reset, and then the standby power supply is turned on.
And step eight, replacing the main power supply with the standby power supply to perform emergency power supply on the access control device.
Step nine, charging the standby power supply when the main power supply is not damaged.
Step ten, when stand-by power supply opened, the controller sent the signal for normally open gate 5, and normally open gate 5 closed after receiving the signal to completely isolate the passageway between the door frame 1, make the pedestrian can't overturn mainframe box 2 by oneself and come through door frame 1, simultaneously, because of normally closed gate 4 is the normally closed structure, self-closing under the condition of the power supply of lack the main power source has further guaranteed the effect of blocking.
And step eleven, when the standby power supply is started, the controller sends a signal to the remote terminal for alarming through the remote communication module, and informs workers in the remote control room to know the situation in time.
And step twelve, when the identity verification information module fails to verify, and the pedestrian abnormally passes through a channel between the main case 2, the monitoring module 6 sends a signal to the controller, and the controller gives an alarm to the remote terminal through the wireless communication module.
The foregoing shows and describes the general principles, essential features, and advantages of the invention.
