Xi'an access control attendance management system works

The system integrates automatic identification technology, computer network technology, and projection technology to form an integrated system for automatic reporting. The label worn by the conference representative is called a representative card. It is a non-contact IC card with a frequency band of 13.56M and supports the protocol ISO15693. The original TI chip is used to ensure long-distance identification and stability.

The open channel reader adopted by this system is a high-frequency radio frequency automatic identification system developed by Shanghai Hao Bin Information. The working mechanism is that each tag has a 64-bit globally unique ID number. When the tag enters the sensing range of the card reader, the tag is activated by the electromagnetic inquiry signal emitted by the reader continuously. , which feeds back to the reader a response signal carrying an ID number and data. It is through the interrogation and response of signals between the electronic tag and the card reader that the card reader can accurately and quickly recognize the carried in the electronic tag. The ID number and data, and read the electronic tag ID number and data output to the computer, external controller or other terminal device in accordance with a certain output format, so as to achieve the identification of electronic tags.

There are 2048bits of data storage space in the RFID electronic tag, which can be used to store some of the basic information represented, so as to avoid storing all data in the back-end database, increasing the burden and instability of the system. As long as the representative wears the identification card to go everywhere. To meet, even if the back-end database is not the same, as long as it is a legitimate reader, the basic information of the delegate can still be read, this is the current ID card can not do.

When the representative wearing the electronic tag arrives at the entrance to the terminal, the nearby reader will transmit the ID number of the tag via RS232 (RS485, TCP/IP or wireless) to the reporting terminal and report it to the terminal. The data (the read electronic tag ID number) is transmitted to a remote computer server via a computer network. In this way, the reporting terminal and inquiry terminal connected to the server can update data in real time: the reporting terminal displays real-time information such as the name of the photo represented by the channel, and simultaneously inquires the terminal of real-time display of the real-time conditions and statistical data of the meeting report, such as the number of users. The actual number and the number of people who did not arrive.
