Overview
According to statistics, more than 90% of illegal intrusions are entered through existing entrances and exits. Therefore, the management and protection of entrances and exits is a very important part of modern social security prevention technology.
With the continuous development of the world economy, the access control management system has become an indispensable part of intelligent buildings, parking lots, hotels, hotels, computer rooms, banks and even residential communities. As the most powerful and complete system in the access control series, the networked access control management system plays an irreplaceable role for other systems in security protection, efficient automation of entrances and exits, and intelligent management.
The E.CH networked access control management system has the most comprehensive and complete networking methods in the world, including RS485 networking, wireless networking, GPRS networking, TCP/IP networking, and the most advanced CAN bus group Net way.
2 Basic working principle
The system uses RFID proximity cards, and all personnel need to use an authorized RFID proximity card to enter. When the cardholder is within the valid range of the card reader, the card reader will verify the data (password) in the card and transmit it to the controller at the same time, and the controller will automatically recognize this signal instantly, including the card number, location, valid time period, etc., If all meet the requirements, the controller will activate the electronic door lock. At this time, the controller and the main control computer will record the card number, name, access time, and access control points of the cardholder in real time, and can print reports at any time as needed. If the main control computer is installed with attendance software, the staff’s commuting status can be counted and analyzed based on these card swiping records, so as to achieve the purpose of attendance. If the cardholder does not have access rights, the controller will refuse to open the door and can give an alarm. If the door is forced to enter or the door is opened overtime, the system will automatically transmit the alarm signal to the main control computer for processing by the security personnel. In this way, the purpose of prohibiting entry of persons without legal status is achieved, and the security of the unit or department is greatly improved. If the card is accidentally lost, as long as the card is cancelled in the software of the controller or the main control computer, the card no longer has the authority to open the door.
3 Application scope and purpose of RFID access control attendance management system
The main application scope of the access control management system includes: senior staff office, R&D center, experiment center, financial center, network management center, security center, computer room, main control room, main equipment room, factory, school, freight center, parking lot, mining unit , Personnel archives management center, community entrances and exits and other important passages, and cooperate with the fire protection, monitoring, anti-theft and other systems to implement security linkage to achieve the greatest sense of security protection.
The three most basic elements of the access control system are “3W”: When, Where, Who. That is, who can enter and exit where and when, in order to enhance the convenience and real-time of safety management, and realize scientific and effective management of entrances and exits.
4 Advantages of RFID induction access control and attendance management system
