Access control system (ACS) is a control system that adopts modern electronic technology and software information technology to identify the target through correct identification at the entrance and exit, determine the release or rejection of the target, and perform operations such as recording and alarming at the same time. Entry and exit numbers, entry and exit times, and entrance/exit numbers are registered and stored to ensure the security of controlled areas and targets and intelligent management.
Entry and exit control systems are widely used in smart building security, vehicle management, logistics management, security, banking and other fields.
The goals of control include people and things. In the intelligent building security management system, the main control is the person. This system is usually called the access control system. This article focuses on the different identification technologies in the intelligent building entrance and exit control system.
The composition of the entrance and exit control system
The entrance and exit control system is mainly composed of a reading part of the identification mark, a management/control part, an execution part, a transmission part, a corresponding management software, and a cloud server. The typical system is as follows:
The entrance and exit control system has a variety of construction modes. According to its hardware configuration mode, it can be divided into integral type and split type; according to its management/control mode, it can be divided into independent control type, network control type and data carrier transmission control type.
All components of the integrated entry and exit control system are internally connected, combined or integrated to realize all the functions of the entrance and exit control.
The various components of the split-type entrance and exit control system have separate parts in structure and parts that are combined in different ways. The separate and combined parts are connected together as a system through electronic, electromechanical and other means to realize all the functions of the entrance and exit control.
Independent control type entrance and exit control system, all functions of its display/programming/management/control of the management/control part are completed in one device (entrance controller).
The networked control type entrance and exit control system does not have all the display/programming/management/control functions of its management/control part completed in one device (entrance controller). Among them, the display/programming function is completed by another device. Data transmission between devices is achieved through wired and/or wireless data channels and network devices.
