Three Roller Gate

Three Roller Gate also known as the three-roll door, it is a kind of channel gate, which belongs to the intelligent control terminal equipment of the entrance and exit of the people flow channel.

一、Definition and use

The three-roll brake machine is a special equipment for personnel to go through security check or control at the entrance. It is widely used in a variety of places that need to control personnel access, such as restaurants, hotels, office buildings, museums, stadiums, clubs, subways, stations, wharfs, tourist attractions and so on.

二、Working principle

The working principle of the three-roll brake mainly includes several aspects such as detecting signals, opening the brake, passing the verification, closing the brake and alarm functions:

Detection signals: Three-roll brakes are usually equipped with infrared sensors to detect whether pedestrians are approaching or passing through the gates. When someone approaches the gate, the infrared sensor senses it and sends a signal to the control system.

Open the gate: After the gate control system receives the signal of the infrared sensor, it will issue an instruction to open the gate. In general, the gate will drive three horizontally mounted rotating sticks through the motor, so that it rotates from the vertical state to the horizontal state, forming a whole channel.

Pass verification: On both sides of the access channel, the gate is usually equipped with identity verification devices such as card readers or fingerprint readers. Pedestrians need to use valid credentials (such as access cards, ID cards, fingerprints, etc.) for verification. If the credentials are valid, the gates will remain open and allow pedestrians to pass through.

Close the gate: After the pedestrian passes through the gate, the gate control system will automatically detect whether the channel is clear. If there is no obstruction, the command is issued to restore the gate to the original vertical state and close the channel.

三、Product category

According to the traffic direction, the three-roll brake can be divided into two kinds: one-way three-roll brake and two-way three-roll brake. One-way three-roll gates allow pedestrians to pass in only one direction, while two-way three-roll gates can be set to two-way or one-way traffic as needed.

四、Material characteristics

The three-roll brake is usually made of 304 stainless steel material, which has the characteristics of durability and is not easy to deformation. The choice of this material allows the three-roll brake to adapt to a variety of harsh environments and maintain long-term stability and reliability.

In summary, the three-roll brake is an efficient, safe and reliable access control equipment. It ensures the orderly and safe entry and exit of personnel through advanced detection, verification and alarm technology.
