Access control system design and access control system principle

The access control system is an indispensable part of the intelligent building security automation system and is also one of the necessary systems for all intelligent buildings. According to the latest intelligent building design standards, the access control system and the anti-theft alarm system, closed-circuit television monitoring system and electronic patrol system constitute the main part of the intelligent building security system. Therefore, nowadays, regardless of the size of enterprises, units, office buildings, banks, and even residential quarters themselves have begun to use the access control system. Today, we will learn about the design of the access control system and the principles of the access control system .

With the continuous advancement of science and technology, people have also raised higher and higher requirements for the automation level of work and life. The access control system was born to meet people's needs for higher-level security management of modern offices and living places. At present, the commonly used access control systems mainly include biometrics (fingerprints, palms, irises, etc.) and access control systems represented by radio frequency card systems.

Different forms of door installation requirements for access control systems are not the same. Here we will introduce the most common access control systems for everyone.

1. The schematic diagram is a schematic diagram of the structure of a control point of a door. An AC220V socket must be left near each door as a power take-off port. An 8-core super five cable (usually a computer network cable) must also be installed to the nearest LAN switch or HUB as the network cable. These two tasks must be done. If the access control system uses the 485 local area network connection method, it needs to use twisted pair shielded wire to ensure the stability of the communication system. If the access control system adopts the TCP/IP communication method, the type 5 network cable is selected as the communication wire. Ensure the normal communication of the system.

2. For the occasion of frequent power off can be equipped with their own batteries, battery capacity determines the length of time after the use of breakpoints, for the occasion does not often power off the battery can not be installed.

3. The door magnet is a sensor that detects the door open/close state. If a door magnet is installed, the door's switch action and the door's state can be seen on the local area network management computer. Similarly, if it is a remote Internet control management, you can see Thousand kilometers away from the opening and closing of the door and the state of the door. If the user does not need to be installed. Magnetic wire can be used two-core wire.

4. The exit button can directly control the opening of the door. When the controller is pressed gently, the door opening action is performed. The exit button can be installed in parallel as required. The exit button is generally installed at the front desk reception and security office so that the door can be opened for the guest without going to the door. If the user does not need to be installed. The wire for the exit button can use two wires.
