The turnstile is also a kind of entrance and exit control equipment. Because of its special control function, it can effectively prevent illegal entry behaviors such as climbing and crossing. Therefore, it is often used in various special control areas that require stricter control requirements. People need to have special permissions before they are allowed to pass. The speed of the turnstile is about 30 people per minute.
Product structure and working principle of turnstile: 1. The mechanical part of the turnstile
The mechanical part of the turnstile (door) is divided into two parts: the structure frame and the movement. The structure frame is used as the carrier, and the main components of the movement are the motor, the optocoupler plate (single and dual circuit), the transmission shaft, the electromagnet, etc.;
2. Rotating gate control part
The control part of the turnstile (door) is composed of an industrial-grade main control board, a transformer, a battery, a relay, and an air switch.
3. The working principle of the system
1) Turn on the power, and the system will enter the working state 2 seconds after the main board of the revolving door, and the left and right positioning arms will automatically lock.
2) Use the manual button to open the gate signal to the main board. After the main board receives the gate opening signal, the main board sends out the gate opening instruction, the relay is closed, and the electromagnet is energized to open the left and right positioning arms to reach the gate opening requirements, and wait for pedestrians to pass (passing time for pedestrians) The default is 10S, if it exceeds 10S, the pass will be cancelled).
3) After the turnstile is powered off, the battery-powered main control board sends out a normally open command, and the motor drives the drive shaft to limit the position through the double-way light-coupling plate. The revolving door is normally open to allow pedestrians to pass freely, meeting the fire protection requirements.
