Full height rotary gate is mainly used in access control occasions to prevent violent impact, such as football field, prison, etc. Compared with other gates, the main advantages of full height rotary gate are: strong, impact resistant and can not be illegally crossed. When selecting full height rotary gate, the following aspects need to be paid attention to:

1. Strong impact resistance: the rotating rod and peripheral guardrail need to be strong and able to withstand large destructive force.

2. Safety: the biggest worry of the full height rotary gate is that the audience is locked in the gate and can't enter or exit. In any case (such as sudden power failure), this situation must be avoided and designed according to the principle.

3. The rotating arm has large weight and inertia. When the rotating arm is in place, there should be no oscillation.

4. Reliability: the reliability of the gate is based on the reliability and integration mode of various components of the gate. Selecting good quality components is the basis, such as card reader, controller, display, etc; The integration mode mainly depends on the design and selection of control unit and communication mode. The existence of lightning protection components is also related to the reliability of the equipment.

5. Rotation life: the moving parts will be worn, and the design and selection of key parts are reasonable.

6. Glass material above the barcode reader: the upper part of the barcode reader must be transparent. Plexiglass is low cost and easy to process and install. However, after multiple ticket swiping, the glass will be worn and rough, affecting the reading speed and accuracy of the barcode. Therefore, wear-resistant quartz glass must be used;

7. Ticket inspection speed: for the large flow passage of the gate, the ticket inspection speed is a very important index. The ticket checking speed depends on the gate control mode, communication networking mode, ticket checking processing software and mechanical action speed. Generally, the gate response speed is within 500ms.
