Access turnstile (turnstile solenoid) is a pedestrian passage management device, which is widely used in public places. Its hardware components include body, mechanical arm, card reader, controller and light indicator. The working principle is: after the user swipes the card or scans the code, the card reader identifies the identity information and sends it to the controller. The controller determines whether to allow the mechanical arm to be opened after judging the user’s authority. At the same time, the light indicator shows the access status. Access turnstile (turnstile solenoid) also has anti-pinch, anti-collision functions and data collection and remote monitoring functions. Access turnstile (turnstile solenoid) is a common pedestrian passage management device that can identify and control access rights through identity recognition. It is widely used in public places such as subway stations, airports, and bus stations. What are the basic components of access turnstile (turnstile solenoid)? Below we will analyze it in detail from two aspects: hardware composition and working principle.

1. Hardware composition

2. Body: The appearance of access turnstile (turnstile solenoid) is usually made of stainless steel or aluminum alloy, with a solid structure, beautiful appearance and corrosion resistance.

3. Robotic arm: the key part of the access turnstile (turnstile solenoid), used to control access rights, usually driven by a motor, and can achieve one-way or two-way access control as needed.

4. Card reader: used to identify the identity information of the card swipeer, including two types of inductive IC card readers and barcode scanners.

5. Controller: the core component that controls the operation of the access turnstile (turnstile solenoid), including control circuits, drive power supplies and other parts.

6. Light indicator: used to display the access status for user identification.

7. Working principle

8. Normal working process of access turnstile (turnstile solenoid)

After the user swipes the card or scans the code, the card reader identifies the identity information and sends it to the controller. The controller determines whether to allow the robotic arm to be opened after judging the user’s authority, and the light indicator displays the access status. When the user passes, the robotic arm will automatically close to ensure the safety and order of the passage.

1. Safety function

As a safe passage device, access turnstile (turnstile solenoid) is designed with a variety of safety functions: one is the anti-pinch function, when the mechanical arm is blocked by external force, it can automatically reverse to protect the user from injury; the other is the anti-collision function, which prevents the mechanical arm from colliding with the user or other objects and damaging the equipment.

1. Data management and remote monitoring

Access turnstile (turnstile solenoid) usually has data collection and monitoring functions, and can achieve remote monitoring and data management through network connection, which is convenient for managers to conduct traffic data statistics and equipment status monitoring. In summary, access turnstile (turnstile solenoid) as an intelligent traffic management device, through precise hardware composition and efficient working principle, realizes strict control and safety guarantee of personnel traffic. It not only improves traffic efficiency, but also improves the level of site management, which is of great significance to promoting urban intelligent construction and public safety management.
