Swing Barrier Turnstile structure

1. Box

Protect the movement, control module and other internal components, and play a supporting role.

The main Swing Barrier Turnstile is usually 304 or 316 stainless steel, and the auxiliary materials include plexiglass, tempered glass, resin, stone or wood. The selection of materials generally needs to consider strong, beautiful, not easy to deformation, scratch and scratch proof, rust and corrosion proof, easier to process and fix.

2. Blocking body

Acts as a barrier about Swing Barrier Turnstile when pedestrians are not allowed to pass, and opens the pass when pedestrians are allowed to pass. It is usually implemented in the form of a door or bar.

The selection of materials generally needs to be considered strong, can withstand a certain impact, but its own impact can not be harmful to people, Swing Barrier Turnstile weight is as small as possible, beautiful, rust and corrosion prevention, easy to process and fix, and not hurt after damage.

3. Movement

It is composed of various mechanical components as a whole (including drive motor, reducer, etc.), and uses mechanical principles to control the opening and closing action of the arrester.

The key factors affecting the performance and service life of the movement include the processing technology and material of the mechanical components, and the most important drive motor and matching reducer.

The drive motor is usually DC brush motor or DC brushless motor. Dc brush motor cost is low, the control technology is relatively simple, so it is widely used by domestic brake manufacturers, but the carbon brush is easy to lose parts, need regular maintenance and replacement. Dc brushless motor has no carbon brush, does not exist this loss, and has a long service life. If you want to improve the performance and service life of the movement, then the use of better performance, longer service life of the DC brushless motor is a good choice, especially the European first-line brand of DC brushless motor, its reliability and durability are ordinary motors can not be achieved, but the cost is high, the control technology is also very complex. Among the domestic brake brands, the use of imported DC brushless drive motor is [Cimoro CMOLO]; Among foreign brake brands, there are [Kaiba KABA], [Gulibao GUNNEBO] and so on.

4. Control module

Microprocessor technology is used to control various electrical components and drive motors.

The microprocessor is generally used, but if the control system is more complex, or needs to be integrated with many other systems (including ticketing systems, access control systems, etc.), and the response time is very high, you need to use a higher performance ARM processor or even Cortex processor.

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 configured with a special industrial computer to achieve.

5. Auxiliary module

Including LED indicator module, counting module, pedestrian detection module, alarm module, authority input module, voice prompt module and so on.

LED indicator module: generally composed of LED dot matrix or LED display, used to indicate the status and direction of the gate, and some also contain text or patterns and other prompt information and welcome information.

Counting module: used to record the number of passengers, can be displayed through the LED digital tube or display screen, can clear and set the upper limit of counting.

Pedestrian detection module: used to identify the pedestrian status, determine whether the pedestrian is legal to pass, and can determine whether the pedestrian is in the movement range of the arrester, in order to protect the personal safety of the pedestrian. The performance of the detection module is very critical, affecting the effectiveness and safety of the gate, which is mainly determined by two factors: hardware - sensor and software - recognition algorithm. The sensor generally adopts infrared photoelectric switch (more common) or infrared curtain, and the infrared photoelectric switch is divided into a pair of beam type (more common) and a single reflection type; High-end gates will use more than 10 pairs of imported infrared photoelectric switches, special occasions will use high-performance infrared curtains or other special sensors.

In addition, the recognition algorithm is also very important, the height, step and speed of different pedestrians are different, the size and location of luggage are also diverse, but also take into account the number of people continuous through the front and back spacing (anti-trailing), some occasions also consider the situation of riding a bicycle, high-end brake manufacturers generally establish the corresponding mathematical model according to a large number of experimental data, The self-developed recognition algorithm can effectively identify common traffic targets such as pedestrians, luggage and bicycles, and the anti-tailgating distance can reach within 20mm (such as IDL, [Cimoro CMOLO], etc.), which also depends on the sensor recognition accuracy and algorithm, and the anti-tailgating distance of the ordinary gate can only reach 100mm.

Alarm module: the gate will trigger an alarm under various abnormal use conditions, which is used to prompt or warn pedestrians, managers and maintainers, including illegal passage, abnormal gate, powerup self-test, etc., alarm methods include buzzer (more common), light, voice, etc. (can be used comprehensively).

Permission input module: pedestrians need to let the gate "know" whether they have legal permission to pass before passing, that is, "input" permission to let the gate judge whether they can be released. There are many types of input methods, such as contactless IC card swipe, biometric identification, input password, coin, etc., simple to have direct button access. The module is usually combined with an access control system or a ticketing system. This module is not required in the case of free passage.

Voice prompt module: The voice prompt here is different from the voice alarm in the previous alarm module, which is mainly used to assist in prompting pedestrian-related information, such as the type of ticket, welcome information, etc. This module is less commonly used and needs to be customized by the user from the manufacturer.
