Door entry control, also known as access management control system, is a digital management system that organically combines information technology, electronic technology, and mechanical locks to identify the entering and exiting personnel with the appropriate level of authority and perform corresponding control.
The RFID door entry system replaces the traditional mechanical keys, reducing the trouble of key management, and effectively avoids the loss of keys. At the same time, it can record and query the information of entering and exiting personnel, which has incomparable superiority compared with ordinary mechanical locks.
1. The principle of Independent RFID door entry system
Independent door entry control is non-network type, each door lock is independent, and its information reading mode is usually plug-in type and inductive type.
The principle is that the card reader is used to read the smart card information of the person who swipes the card, and then convert it into an electrical signal and send it to the RFID door entry system controller. The controller uses the software to determine whether the cardholder has been authorized according to the card number received. During this period of time, you can enter the gate, and complete the work such as unlocking and keeping locked according to the determination.
2. The principle of networked RFID door entry system
The networked door entry system is composed of a controller, a card reader, an electric control lock, a door opening button, etc. It manages all the information analysis and processing in the system through the computer equipped with the software of the door entry system.
The principle is that the RFID door entry system controller receives personnel information and corresponding authorization information sent from the management computer, and at the same time transmits the card entry and exit records to the computer. A single controller can form a simple door entry system to manage one or two doors. Multiple controllers are connected to the computer through the communication network to form the door entry system of the entire building.
The RFID door entry system is developed on the basis of traditional door locks, and its security has been improved and developed with a great leap in recent years. Nowadays, fingerprint door entry systems, facial recognition door entry systems, and so on, which have been spawned by new technologies have ensured the residency safety of more and more families and enabled the door entry systems to be applied in more and more fields.
