Working principle of access control gate

The access control gate is composed of a passage gate and an access control system. It is different from the use of three roller gates and is generally used in various entrances and exits of office buildings and factories. Today, the gate manufacturer Beijing Simolo takes everyone to understand the working principle of its access gate, which is of certain help for the selection and installation of gates in the project.

Working principle of access control gate
The access control gate machine integrates machinery, electronics, microprocessor control and various identification technologies organically. By selecting different access control systems, visitor systems, biometric identification systems, etc. to achieve multi-functional entrance and exit management requirements, the main working principle It is to control the operation of the blocking body by human power, the mechanical limit controls the movement of the movement, the semi-automatic type uses the electromagnet to control the movement and stop of the movement, and the fully automatic type uses the motor to control the movement and stop of the movement. The movement and stop of the movement further control the opening and closing of the blocking body. When the person passes the pedestrian swing gate, if the person does not leave, the buzzer will alarm through the infrared detector, and the door will remain closed. If the door is opened, if the unauthorized pedestrian enters the door detection area, the access control gate The gate will close immediately.
The introduction of the working principle of the access control gate is provided by the technicians of Beijing Ximoro. We specialize in the production of gate equipment, including three roller gates, swing gates, wing gates, translation gates, rotary gates and other gate hardware for different entrances and exits. The gate system software, if you are interested, you can always pay attention to the gate manufacturer Beijing Simolo.
The main products of access control gates include intelligent swing gates, intelligent wing gates, and popular face recognition gates.

National Hose thread (NH) couplings, also known as National Standard Thread (NST). It is the most common type of fire hose coupling used in the United States. The male and female straight (non-tapered) threads screw together and the connection is sealed with a gasket.

NH Coupling include brass and aluminum NH couplings

NH couplings were used widely in Canada, USA and South American zone.

Main sizes include 1.5``,2`` and 2.5``.
