1. Introduction to the working principle of the access control turnstile:
Turn on the power, and the system will enter the working state after 5 seconds. When the card reader of the access control turnstile reads a valid card, the access control panel sends a switch signal after judging and processing the read card information;
The main control board of the access control turnstile receives the switch signal of the access control board, and after comprehensive processing, sends an effective control signal to the direction indicator and the motor, so that the direction indicator turns into a green arrow pass sign. In the closed mode, the motor runs, the built-in encoder of the motor controls the rotation angle of the motor, and the gate is opened (in the normally open mode, the motor does not act), allowing pedestrians to pass;
After the pedestrian passes through the access gate according to the direction indicator arrow, the infrared beam senses the whole process of the pedestrian passing through the passage, and continuously sends a signal to the main control panel until the pedestrian has passed the passage and then the gate is closed;
If a pedestrian forgets to read the card or reads an invalid card and enters the passage, the system will prohibit pedestrians from passing, and will issue an alarm, and the alarm will not be released until the pedestrian exits the passage; the valid card will be re-read to allow passage;

When using the access control turnstile, pay attention to:
Do not pass the access gate in the reverse direction. The access gate has an anti-retrograde function of the passageway, which may be caught and cause an accident;
When passing through the gate, do not crowd, and keep a certain distance between people to avoid injury accidents;
Do not follow the access control turnstile, follow the principle of one person, one card, the gate has an anti-trailing function, and the trail may be caught.
Children who are less than 1m tall should pass through the gate under the supervision of an adult;
When pedestrians read the card to access the access control turnstile, if the direction indicator sign does not turn green, it is strictly forbidden to enter the access control turnstile;
When pedestrians pass through the gate, do not stay in the middle of the gate for a long time to avoid being caught and causing congestion;
2. Introduction to the structure and composition of the access control turnstile:
access control turnstile
Access control system: It consists of main control board, servo motor control box, servo motor, infrared beam, direction indicator, alarm, transformer (12V), etc.
The main control board of the access control turnstile: the control center of the system, it receives the signals from the card reader and infrared radiation, and after logically judging and processing these signals, and then issuing execution commands to the direction indicator, servo control box, and alarm .
access control turnstile servo control box: control the operation of the motor and communicate with the host computer;
Infrared radiation of access control turnstile: detect the position of pedestrians and play a role in safety protection;
The direction indicator light of the access control turnstile: display the current traffic sign status of the passage, and guide pedestrians to pass through the passage in a safe and orderly manner;
access control turnstile alarm: when the system detects a pedestrian who has entered the passage illegally, it will issue an alarm prompt;
The above is some introduction to the working principle and structure of the access control turnstile. Have you gained a deeper understanding of the access control turnstile through this article?
