Workflow and principle of face recognition gate

The face recognition gate is generally composed of a face recognition tablet + a pedestrian passage gate. The main feature is that the face recognition system visitor can collect the face at the visitor machine with the certificate or collect the face through WeChat. . Whether you want to buy and install face recognition turnstiles or pass through face recognition turnstiles often, are you curious about their workflow principles?
Workflow and principle of face recognition gate
The general face recognition gate can not only pass through face recognition, but also have the function of swiping through the card gate. The following is the specific workflow and principle.
1. The working process and principle of swiping the card through the face recognition gate:
1. Turn on the power and enter the working state after 3 seconds.
2. When the card reader reads the useful card, the buzzer will sound and sound, prompting pedestrians to read the card successfully; at the same time, it will recognize and process the information read from the card, and will request through the signal Notify the main control panel.
3. The main control board accepts the signal from the card reader and the infrared sensor. After sensing and processing, it notifies the direction indicator and the motor of useful control signals, so that the direction indicator sign turns into a green arrow channel sign. If the system is in a normal shutdown state, The motor works, the limit switch controls the turning point of electric manipulation, and the door opens (when the motor is not in the open state, the motor does not move, allowing pedestrians to pass.
4. After the pedestrian passes the face recognition gate according to the direction indicator, the infrared sensor senses the whole process of the pedestrian passing through the face recognition gate, and continuously informs the main control panel of the signal until the pedestrian passes the face recognition gate.
5. If the pedestrian forgets to read the card or the card is invalid and enters the face recognition gate, the swing gate system will prevent the pedestrian from passing through.
Second, the face recognition gate face recognition through the workflow and principle:
1. Visitors can make an appointment to collect faces through WeChat. After the respondent passes, the visitor will pass the gate with his face. Or the visitor can collect the face on the self-service visitor machine with the reservation code after making an appointment through WeChat. The visitor then passes through the gate or passage gate through the face.
2. Visitors who have not made an appointment can go to the artificial visitor machine at the front desk to have their faces collected after registering their documents. Then pass through the gate or the channel gate through the face.
3. The company personnel of the unit can enter and exit the gate or the channel gate through the face and record the time, which can be used as the basis for attendance.
