Barrier-free channels consist of RF reading, RF tags, and infrared modules. The RF reading module is used to read the information in the radio frequency tag, which is the core part in the barrier-free channel. RFID tags are used to store personnel, identity information and other specified information. The infrared module is used to judge whether there are people or items in the channel and play an auxiliary role. 
system structure
â—† The system adopts distributed database management. All the data exists in both the central database and the local database. When there is data change (such as account opening, loss reporting, and account cancellation), the data is automatically synchronized through the network at each management workstation.
â—† When the network or server fails, it will not affect the operation of the channel control system.
â—† If the network or server fails, all data will be automatically stored in the management workstation database, and will automatically pass through when the failure recovers.
â—† The data transmission adopts the CRC check mode to verify and ensure the correctness of data transmission.
The main components
(1) Data server: Stores all personnel information files, logs in and out of records, and captures images when passed.
(2) Card issuing workstation: The cardholder's file management is used to complete card issuance with a card reader.
(3) Communication and monitoring workstations: Complete the channel access records and 24-hour monitoring tasks.
(4) Channel Machine: Real-time feed-in and return-out records, alarm when an illegal person enters or exits.
(5) Surveillance Camera: Monitors and photographs people entering and exiting.
working principle
After the person or item carrying the radio frequency tag enters the reading area of ​​the barrier-free channel, the radio frequency tag will be activated. The radio frequency reading module reads the ID number and data information stored inside the tag and sends the information to the background server, and the background server performs subsequent processing on the data.
