Turnstile parts are an important standard for measuring turnstile gate quality. Many turnstile manufacturers are not willing to disclose what types of turnstile parts they use, and many customers also purchase turnstile gates in a daze. They are not sure what type of turnstile parts actually uses. Let’s analyze the turnstile parts in detail.
The turnstile parts are mainly divided into mechanical parts and control parts. The mechanical part is divided into a structural frame and a turnstile mechanism. The structure frame is used as the carrier, and the turnstile mechanism is mainly composed of a motor, optocoupler small board (single or double), transmission shaft, electromagnet, etc.; the turnstile gate control part is composed of the industrial main control board, transformer, storage battery, relay, air switch, etc.
Sometimes, when we understand a security turnstile product, we cannot just look at its surface or its appearance. We must deeply understand all turnstile components and all turnstile accessories to better understand the quality of the turnstile, and then better use the turnstile to make it serve us and solve our security access control management problems.

Whether it is to use or install the turnstile gate, or to make it realize the required functions, we need to have a deep understanding of the turnstile components, which can help us quickly find and solve problems. Let’s briefly introduce the turnstile components.
The turnstile gate is mainly composed of internal structure and external structures. The outside mainly includes the turnstile chassis, blocking rod, swipe cardboard, face recognition machine, scanning area, and so on. The internal structure mainly consists of the turnstile mechanism, a control module, an integration module, and an auxiliary module.
The auxiliary module is an indispensable part of the turnstile gate to achieve various functions. For example, there are pedestrian detection modules responsible for pedestrian traffic detection, and alarm modules responsible for safety alarms. We will introduce these modules in detail below.
Based on the above general understanding of turnstile parts and turnstile components, we can list the main turnstile accessories, including turnstile chassis, turnstile mechanism, turnstile controller, blocking rod, control module, integration modules, auxiliary modules like led instruction modules, counting module, pedestrian detection module, alarm module, voice prompt module, permissions input module.
Next, Let’s introduce these turnstile accessories and turnstile components in detail.
The turnstile chassis is the outer shell component of the turnstile gate machine, which has functions such as waterproof, dustproof, and anti-corrosion. Generally made of stainless steel or aluminum alloy material, it has the characteristics of high strength, aesthetics, and durability.
The turnstile chassis is to protect the internal turnstile components such as the mechanism, control module, and so on. Can also play a supporting, aesthetic role. The main material is usually 304 or 316 stainless steel, and the auxiliary material includes plexiglass, toughened glass, resin, stone or wood, etc. Material selection generally needs to consider strong, beautiful, not easy to deform, anti-scratch, anti-scratch, anti-rust, anti-corrosion, and easy to process fixed.
The usual processing procedures of the turnstile chassis shell are opening, bending, cutting, welding, grinding, and so on. The turnstile chassis shall have a certain waterproof performance, especially the outdoor turnstile chassis.

Turnstile mechanism is composed of all kinds of mechanical components (including a driving motor, reducer, etc.), which is called the mechanism of the turnstile gate and uses the mechanical principle to control the opening and closing action of the blocking body. The turnstile mechanism adopts high-precision transmission components, which have the characteristics of high precision, good stability, long service life, and low noise.
The turnstile mechanism is the key factor affecting the performance and service life of the machine including the processing technology and material of the mechanical parts, as well as the important driving motor and the matching reducer.
Drive motor usually uses DC brushless motor or DC brushless motor. The cost of a DC brush motor is low and the control technology is relatively simple, so it is widely used by domestic turnstile gate manufacturers, but the carbon brush belongs to the consumable parts and needs to be maintained and replaced regularly. The turnstile mechanism is the most important part of turnstile components.
DC brushless motor without carbon brush, there is no loss, and the service life is also longer. If we want to improve the performance and service life of the machine, it is a good choice to adopt a DC brushless motor with better performance and longer service life, especially the first-line brand DC brushless motor in Europe. Its reliability and durability are not achieved by ordinary motors, but the cost is very high and the control technology is very complex.
When pedestrians are not allowed to pass, the blocking body or blocking rod will open and release.
Material selection generally needs to consider strong, can withstand a certain impact force, but its own impact force can not hurt people, weight as small as possible, beautiful, rust-proof and corrosion-proof, easy to process fixed, and damage after no injury.
The turnstile gate blocking body can orderly manage the entry and exit of personnel. It plays the role of arresting when pedestrians are not allowed to pass through the pedestrian turnstile gate and will be opened and released when pedestrians are allowed to pass through the turnstile gate. The turnstile gate blocking body is generally realized in the form of a crossbar, wing door, and swing door.
The main material of the pedestrian turnstile gate blocking body is usually stainless steel, plexiglass, tempered glass, resin, wood, and other materials.
The material selection of the turnstile gate blocking body generally needs to be considered to be solid and can withstand a certain impact force, but its own impact force can not harm people. It should be as small as possible, beautiful, rust and corrosion-resistant, easy to process and fix, and will not hurt people after damage.
Special patterns, characters, or prompt information can be processed on the blocking barrier body of the pedestrian turnstile gate to increase safety and aesthetics.
Turnstile controller is the core component and important part of the turnstile gate, which uses microprocessor technology to control various electrical components and drive motors of the turnstile gate. It is mainly used on various pedestrian turnstile gates to realize the safety management of people in and out. Through setting, it can realize the normal opening and normal closing of two-way and one-way passages. It can adjust the effective passage time, has the counting function, and has the function of a power failure and rod dropping at the same time.
The turnstile gate contains multiple modules, which require coordination and cooperation between each module in order to achieve flexible and efficient access control management. When designing each module, it is necessary to consider its waterproof, dustproof, and shockproof characteristics based on factors such as its placement and usage environment, in order to ensure the reliability and stability of the turnstile gate machine.
The control system is the brain of the turnstile gate machine, mainly including modules such as the control board, power supply, and lock control. The control board is responsible for the control of asynchronous motors and the implementation of electrical control logic. The power supply mainly provides power support for the gate, while the locking control ensures the safety of the turnstile gate.
Microprocessor technology is used to control various electrical components and drive motors.
In short, it is the motherboard module that controls the gate switch, which normally opens, normally closed, and so on. For turnstile components, the control module is an important part as well.
Microprocessors generally use single-chip computers, but if the control system is more complex, or needs to be integrated with many other systems (including a ticketing system, access control system, etc.), and the response time is very high, it needs to use an ARM processor or even cortex processor with higher performance.
The simple control circuit is generally realized by the main control board, the motor control board, and the auxiliary control board, and the complex control circuit (such as the subway ticket checking machine) needs to be equipped with a special industrial control computer to realize it.
Including LED display module, counting module, pedestrian detection module, alarm module, permission input module, voice prompt module, etc., can be selected according to the requirements of users.
The display is mainly used to display the operating status of the turnstile gate and prompt information on personnel entering and exiting the site. The display is generally divided into two types: LED digital screen and LCD screen, which can provide clear and clear information display and operation interface.
Usually composed of an LED lattice or LED display screen, it is used to indicate the traffic state and direction of the turnstile gate, and some also contain prompt information such as text or pattern and welcome information.
For recording the number of people, can be displayed tube or display screen, which can clear and set the upper limit of the count. The counting module and the pedestrian turnstile gate form a simple turnstile counting system.
Pedestrian detection module:
it is used to identify the passing state of pedestrians, judge whether pedestrians pass legally, and judge whether pedestrians are within the movement range of the blocking body, so as to protect the personal safety of pedestrians. The performance of the detection module is very critical, which affects the effectiveness and safety of the turnstile gate.
It is mainly determined by two factors: Hardware sensor and software identification algorithm. The sensor generally adopts an infrared photoelectric switch (more common) or infrared light curtain, and the infrared photoelectric switch is divided into the opposite type used in pairs (more common) and single-use reflective; high-end turnstile gates will use more than 10 pairs of imported infrared photoelectric switches, and high-performance infrared light curtain or other special sensors will be used in special occasions.
Sensors are mainly used to detect information about personnel entering and exiting the turnstile gate, including infrared sensors, photoelectric switches, dynamic sensors, etc. Sensors can adapt to different personnel statuses, heights, distances, and other conditions, ensuring that the gate can efficiently and accurately control and manage entry and exit.
The infrared radiation sensor is mainly used to ensure the safety of personnel passing through the pedestrian turnstile gate and not being pinched by the sudden closing of the blocking body. The safety accessories of turnstile gates mainly refer to infrared radiation sensors. Each pedestrian turnstile gate will be equipped with multiple sensors. The infrared radiation sensor is one of the most important safety parts of turnstile components.
Its working principle is as follows: the device that uses infrared to detect the object feels the signal of the measured object through the shielding of the measured object to the infrared, transforms the signal fed back by the infrared radiation sensor into the code that can be received by the pedestrian turnstile gate according to a certain law, and transmits it to the blocking body control board. The program forms an information command output through calculation and audit, which is used for turnstile gate access records and door opening. The closing command provides information that when an object is detected, the blocking body of the turnstile gate will not be closed.
In addition, the recognition algorithm is also very important. Different pedestrians have different heights, steps, and speeds, and carry a variety of sizes and positions of luggage. It is also necessary to consider the continuous passage of multiple people Front backspacing (anti-tailing). In some cases, bicycle riding should be considered.
High-end turnstile suppliers generally establish corresponding mathematical models based on a large number of experimental data and develop their own identification algorithms, which can effectively identify common traffic targets such as pedestrians, luggage, and bicycles, and the anti-tailing distance can reach within 20mm. This index also depends on the identification accuracy and accuracy of sensors According to the algorithm, the anti-tailing distance of an ordinary turnstile gate can only reach 100mm.
The turnstile gate triggers an alarm in various abnormal use conditions, which are used to prompt or warn pedestrians, managers, and maintainers. These conditions include illegal traffic, abnormal gate, self-examination of power on, etc. The alarm methods include buzzing (more common), lighting, voice, etc. (which can be used synthetically).
Voice Prompt Module:
The voice prompt here is different from the voice alarm in the previous alarm module, which is mainly used to assist with the information related to the pedestrian, such as the type of ticket, the welcome information, and so on. This module is not commonly used and needs to be customized by users.
Permissions Input Module:
Pedestrians need to let the turnstile gate “know” whether they have the right to pass legally before passing, which means,” input “permission to let the turnstile gate judge whether it can be released. There are many kinds of input methods, such as contactless IC card swipe mode, biometric identification, password input, coin input, and so on. There is also a simple way to press a direct button to pass. The module is generally combined with an access control system or ticketing system.
The common turnstile gate is integrated with the access control system, using the access control controller of the access control system as the control module of the passage machine. It is used with the card reader (IC card, second-generation card, fingerprint, finger vein, face, iris, etc.), which can greatly expand the application scene of the channel gate and meet the relevant needs of customers.
The turnstile gate is closely related to the access control system, and few turnstile gates are used alone. Therefore, the integration module is also an important part of the turnstile components.
The above is all about turnstile parts, turnstile accessories, and turnstile components. Of course, this is just a general explanation. The specific details of turnstile components must be more complicated.
