Overview of entrance and exit control system

The core technical element of the entrance and exit control system-feature carrier

The entrance and exit control system adopts modern electronic equipment and software information technology to control the entry, exit, release, rejection, recording and alarm operations of people or objects at the entrance and exit. The system also numbers the entry and exit personnel, entry and exit time, and entry number Logging in and storing in such situations becomes an effective measure to ensure the security of the area and realize intelligent management. The entrance and exit control system is mainly composed of a reading part, a transmission part, a management/control part, an execution part, and corresponding system software. There are multiple construction modes for the entrance and exit control system

 The entrance and exit control system is a system that manages and controls the flow of people, logistics, and information. Therefore, the system must first be able to confirm their identities and determine the legality of their access (behavior). This requires a method to give them a mark of identity and authority, which we call a feature carrier, and the identity and authority information it contains is a feature.

  Characteristic carrier is one of the basic elements of access control. The characteristic is the difference of uniqueness and stability. It can be used to distinguish identities, identify individuals, and also express power. The identity and authority of access control management objects can be given through feature carriers. Such as RFID, magnetic card, barcode, etc.; it can also be expressed by the characteristics of the object itself, such as facial image, fingerprint and other biological characteristics. In the traditional security system, the mechanical lock is a complete access control system, and the key is the feature carrier. The key of a mechanical lock is a feature carrier, and its "tooth shape" is the feature.

   There are many feature carriers that can be used in the entrance and exit control system, such as magnetic cards, photoelectric cards and the most commonly used IC cards. These feature carriers should be used with the holder (person or thing), but they are not identical to the holder, which means that the feature carrier can be held and used by others (things). To prevent this problem, multiple methods can be used, that is, using two or more feature carriers (depending on the security requirements of the system). If a unique and stable feature can be selected from the holder itself as the information that represents the identity, this problem will not exist. Of course, the characteristics from the "holder" are called "biological characteristics", and the characteristic carrier is naturally the holder.
