The working principle of flap barrier
The working principle of flap barrier
1. Turn on the power and the system will enter the working state after 5 seconds;
2. When the face machine/card reader/bar code platform reads the personnel information, it will judge and process the read information. If it is an authorized face/card number/bar code, it will prompt the recognition success and pass the face machine /The access control board sends an opening signal to the main control board of the gate;
3. After the main control board receives the information from the reader and infrared sensor, and performs comprehensive judgment processing, it sends an effective control signal to the motor to turn the direction indicator into a green arrow pass mark, the motor runs, and the limit switch senses the sensor sheet , The signal of in-position is given and the motor stops rotating;
4. The motor rotates at a certain angle, and the gate opens (when in the normally open mode, the motor does not operate), allowing pedestrians to pass;
5. After the pedestrian passes through the passage according to the indicator signs, the infrared sensor detects the whole process of the pedestrian passing through the passage, and continuously sends signals to the main control board until the pedestrian passes through the passage completely;
6. Pedestrians send signals to the main control board after passing infrared, the main control board of the gate controls the motor to reverse, and stops after detecting the signal in place, and the gate is closed.
7. If a pedestrian forgets to read the card or barcode, or when an unauthorized person enters the passage, the system prohibits pedestrians from passing (normally open mode, the gate will be closed; normally closed mode, the gate will not operate;), and an audible and visual alarm will be issued until the pedestrian After exiting the channel, cancel the alarm; re-read the valid card or barcode, or allow passage behind the face of authorized personnel.
