Overview of Turnstile Access Control Systems
Turnstiles are high-tech products designed for intelligent management of pedestrian access. As an upgrade to intelligent swing barriers and tripod turnstiles, these systems incorporate industrial-grade circuit control systems and user-friendly mechanical transmission designs. They are stable, fully functional, high-end, and suitable for places with high foot traffic, including:
- Subway stations
- Docks
- Clubs
- Smart buildings
- Residential villas
- Hotel lobbies
These systems are compatible with various access control systems, such as RFID card access, biometric access, and static electricity testing access. By integrating with flap barriers, they achieve intelligent access control and management.
Structure of Turnstiles
2.1 Main Structure
The body is made of specially processed high-strength stainless steel pipes and plates, ensuring durability and reliability.
2.2 Drive Mechanism
The drive mechanism integrates the control system, transmission system, and electronic lock components into a compact, low-noise, maintenance-free design.
2.3 Main Drive Motor and Control
The system uses a DC motor with the following features:
- Compact size and high output power
- Low noise and maintenance-free
- Low rotational inertia and high precision control
The DC motor utilizes a PWM modulated controller, Hall sensors, and an incremental shaft encoder for automatic speed adjustment and precise positioning. It surpasses traditional VVVF-controlled AC motors in performance.
2.4 Optional Features
Customizable additions include:
- Card readers
- Intercom systems
- Coin acceptors
- Remote control consoles or panels (open, lock, deny access)
Features of Turnstile Access Control Systems
1. Self-check and alarm functions: Simplifies maintenance and usage.
2. Single or bidirectional access control: Achieved via external buttons or remote controls.
3. Automatic reset function:
- The barrier automatically locks after a 120°/90° rotation.
- If no access is made within the set time, the system cancels the access permission and locks the barrier (adjustable delay: 2s, 5s, 10s, 60s).
4. Anti-collision: The barrier remains locked without an open signal.
5. Anti-tailgating: The system locks after each person passes (120°/90° rotation).
6. Fail-safe operation: Automatically unlocks during power outages to meet fire safety requirements.
7. Device compatibility: Works with various card readers via relay switch signals.
8. Flexible access control: Supports single or bidirectional access.
9. Prevents multiple entries with one card: Uses optical technology to eliminate signal delays and ensure single-entry accuracy.
10. External button control:
- Left or right side can remain open.
- Continuous open without power interruption.
11. Remote control and management: Can be customized for integration with management software.
12. Counting function: Tracks entry and exit counts via the control board (customizable).
