Full height turnstile (also known as full height revolving gate or revolving door gate) is a common high security pedestrian channel management device, mainly used to strictly control personnel entry and exit, prevent tailgating or forced entry.
structural composition
Mechanical system: divided into two parts: structural frame and movement. The structural frame serves as a carrier, on which directional finger reading and writing devices are installed; The movement is mainly composed of a motor, a frame, a transmission shaft, a gate, etc.
Electric control system: composed of access card reader, access control main control board, limit switch, transformer, battery, electromagnet, PLC, etc.
Other components: It also includes sensors such as infrared radiation and pressure detection, used for anti pinch and anti tailgating judgment; Some turnstiles are also equipped with hydraulic shock absorbers, which can be freely adjusted to reduce the working noise of the turnstile.
working principle
After turning on the power, the system enters working mode. When the access card reader reads a valid card, it will emit a prompt sound and send a signal to the access control board to apply for approval. After receiving the signal and processing it comprehensively, the access control controller sends effective control signals to the motor to make it run. The limit switch controls the rotation angle of the motor, and the gate opens, allowing pedestrians to pass. When in normally open mode, the motor does not operate.
Application scenarios
Transportation hubs, such as subway stations, train stations, airports, etc., can effectively control the flow of people, maintain order, and ensure the safe and orderly passage of passengers.
High security places: such as prisons, military bases, nuclear power plants, etc., the fully enclosed design of the full height turnstile and strict traffic control can prevent unauthorized personnel from entering and ensure the safety of the place.
Enterprises and institutions: used to control personnel entering and leaving the office area, improve security, and achieve attendance, statistics, and other functions for convenient management.
Commercial complexes, such as shopping malls, shopping centers, etc., can be used to control customer entry and exit, track passenger flow, and set up permission controls in specific areas to ensure the safety and rights of merchants and customers.
Schools and hospitals: Schools can manage the entry and exit of students and faculty through full height turnstiles to ensure campus safety; Hospitals can be used to control the flow of personnel in ward areas, important departments, and other areas, providing patients with a safe medical environment.
Industrial and construction sites: personnel can be restricted from entering hazardous areas or important work areas to prevent accidents and facilitate the management of construction personnel's entry and exit.
Key points for selection
Material and process: Priority is given to using 304 stainless steel material for the full height turnstile, which is sturdy, rust resistant, corrosion-resistant, and impact resistant. At the same time, pay attention to checking the production process, such as whether the welding is firm, whether the surface treatment is smooth, etc. High quality product processes can ensure the stability and service life of the turnstile.
Functional requirements: Select turnstiles with corresponding functions based on actual usage scenarios and needs. If strict anti tailgating measures are required in certain areas, products with strong anti tailgating capabilities should be chosen; For areas with fire safety requirements, power-off pole lowering or power-off free passage function is essential.
Traffic speed: Different application scenarios have different requirements for traffic speed. For places with high passenger flow such as subway stations and train stations, it is necessary to choose turnstiles with faster traffic speed to reduce queue congestion. Generally, a traffic speed of more than 30 people per minute is more suitable.
