What is the internal structure of the barrier gate chassis? What are the functions of the barrier gate?

Abstract: The barrier gate is a passage blocking device used to manage the flow of people and regulate the entry and exit of pedestrians. It is usually composed of a box, a blocking body, a movement, a control module, and an auxiliary module. Its function is mainly a mechanical anti-pinch function. , Remote control function, automatic reset function, entry alarm function, etc., as well as various functions such as face recognition system, fingerprint recognition system, scanning QR code, swiping ID card, fee deduction system, etc. can be customized according to needs. Let’s take a look at the structure and function of the barrier.

1. What is the internal structure of the barrier enclosure?

Barrier gates are commonly used channel management equipment that only pass one person at a time and can be used for entrances and exits in various occasions, mainly in office buildings, factories, scenic spots, construction sites, communities, entertainment venues, gyms, financial institutions, government agencies and other occasions. . The structure of the gate machine is mainly composed of the following parts:

• 1. Cabinet

The box of the gate machine is used to protect the core, control module and other internal components, and play a supporting role. It is generally made of 304 or 316 stainless steel, plexiglass, tempered glass, resin, stone or wood, etc., to choose Strong, beautiful, not easy to deform, scratch-proof, anti-scratch, anti-rust and anti-corrosion, easy to process and fix the material.

• 2. Arresters

It acts as an obstruction when pedestrians are not allowed to pass. When pedestrians are allowed to pass, it will be opened and let go, generally in the form of gates or fences. The arresting body is usually relatively strong and can withstand a certain impact force, but its own impact force should not harm people, and the weight should be as small as possible, beautiful, and it will not hurt people after damage.

• 3. Movement

It is composed of various mechanical components, including drive motors, reducers, etc., and uses mechanical principles to control the opening and closing actions of the blocking body. The drive motor often uses a DC brushed motor or a DC brushless motor. The DC brushed motor needs regular maintenance and replacement. If you want to improve the performance and service life of the movement, then use a DC brushless with better performance and longer service life. Motor is a good choice

• 4. Control module

Use microprocessor technology to realize the control of various electrical components and drive motors. The microprocessor of the gate machine generally uses a single-chip microcomputer, but if the control system is more complicated or needs to be integrated with many other systems (such as ticketing system, access control system, etc.), and the response time is very high, it needs to be used Higher performance processor. The simple control circuit is generally realized by the main control board, the motor control board and the auxiliary control board, while the complex control circuit (such as the subway ticket gate) needs to be configured with a special industrial computer to realize it.

• 5. Auxiliary module

Including LED indicator module, counting module, pedestrian detection module, alarm module, permission input module, voice prompt module, etc.

2. What are the functions of barrier gates?

As a barrier system, barrier gates are widely used and have many functions. In addition to basic functions, functions can also be customized according to requirements. The main functions of barriers include:

• 1. General function

Ordinary barrier gates usually have multiple basic functions such as mechanical anti-pinch function, remote control function, automatic reset function, passage mode selection, entry alarm function, multiple control functions, anti-trailing function, anti-collision function, etc.

• 2. Customized function

The barriers used in different places have different requirements, so special functions can be customized according to the installation location and usage requirements. Common optional customized functions are: face recognition system, fingerprint recognition system, scanning QR code, and swiping identity Certificate, fee deduction system, ticketing system, external LED screen, construction site system, magnetic stripe system, card ejection function, etc.
