Analysis of the Control System and Hardware Composition of Rotary Shutters

1, Control system of rotary gate
The control system of the turnstile is the core of its intelligence, responsible for receiving and processing various input signals, and controlling the operation status of the turnstile. A typical rotary gate control system includes the following key components:
Main control board: The main control board is the "brain" of the turnstile, responsible for receiving input signals from sensors, card readers, etc., and making decisions based on preset program logic to control the actions of actuators such as motors and electromagnets. The main control board usually adopts industrial grade design to ensure stable operation even under high loads and harsh environments.
Sensor system: The sensor system is used to detect the status of people and objects around the gate, including infrared sensors, microwave sensors, etc. These sensors can sense the real-time flow of people in front of the gate, ensuring that the gate opens and closes at the correct time. At the same time, sensors can also detect whether the gate is impacted by abnormal forces, in order to trigger the alarm system in a timely manner.
Card reader and identity verification module: Rotary turnstiles are usually equipped with card readers to read identity information such as access cards, IC cards, RFID tags, etc. These pieces of information are passed on to the authentication module for verification, and only authorized users are allowed to pass through the gate. With the development of technology, some turnstiles also support biometric recognition technologies such as fingerprint recognition and facial recognition, further improving security.
Alarm and monitoring system: When abnormal situations such as illegal intrusion or violent destruction are detected, the turnstile will trigger the alarm system and notify management or security personnel to take corresponding measures. At the same time, cameras are usually installed around the gate, which can monitor the situation in the gate area in real time and provide intuitive monitoring images for management personnel.
Power management system: Rotary turnstiles require a stable power supply to ensure their normal operation. The power management system is responsible for monitoring changes in power supply voltage and current to ensure that the gate operates within a safe voltage range. At the same time, some turnstiles are also equipped with backup power sources, such as batteries, to ensure normal operation for a period of time even in the event of a power outage.
2, Hardware composition of turnstile
The hardware composition of a turnstile is the foundation of its physical structure, including key components such as the structural frame, movement, transmission system, and electromagnet.
Structural frame: The structural frame is the main part of the rotary gate, used to support and fix other components. It is usually made of high-strength materials to ensure the structural stability of the gate during long-term use. The design of the structural framework also considers aesthetics and usability, allowing the gate to integrate into various environments.
Movement: The movement is the core component of the rotary brake, including the motor, reducer, transmission shaft, etc. The motor is responsible for providing power, reducing speed and increasing torque through a reducer, while the drive shaft transmits power to the rotating part of the gate. The design of the movement directly affects the operational efficiency and stability of the gate.
Transmission system: The transmission system is responsible for transmitting the power of the motor to the rotating part of the gate. It usually includes transmission components such as gears, chains, belts, etc. The design of the transmission system needs to consider factors such as transmission efficiency, noise control, and maintenance convenience.
Electromagnets and positioning arms: Electromagnets are used to control the opening and closing actions of gates. When receiving instructions from the main control board, the electromagnet will be powered on or off, attracting or releasing the positioning arm to rotate the gate to the corresponding position. The positioning arm is used to lock the position of the gate when it is closed, preventing illegal entry.
Access card reader and display screen: The access card reader is used to read the user's identity information, while the display screen is used to display the operation status and prompt information of the gate. These components are usually installed on the outside of the gate, making it convenient for users to operate and view information.
Other auxiliary components: The turnstile may also include some auxiliary components such as dust covers, waterproof covers, emergency buttons, etc. These components are used to improve the durability, safety, and usability of the gate.
