RFID technology parking space detection management system hardware composition, custom rfid wristban

　　RFID technology parking space detection vehicle entrance and exit management system hardware composition

　　1) RFID card reader, for parking 2.4G signal coverage, reading the dual-frequency electronic tag information on the vehicle, and connecting through the serial port 485, RJ45, Wiegand 26, relay output and the controller to control the opening and closing of the gate closure.

　　2) The low-frequency activator is installed on the ground of the vehicle entrance and exit. The activator activates and wakes up the dual-frequency electronic tag, resolves the ID of the induction coil and the electronic tag, and transmits the signal in the 2.4G frequency band. Reader for reading

　　3) Dual-frequency electronic tags are placed on vehicles entering and leaving the parking lot to identify the vehicles, and to perform parking space detection and intelligent guidance and reverse car search services for entering and leaving the parking lot.

　　4.1.2 Precautions for the hardware installation of the vehicle entrance and exit management system

　　1) The low-frequency activator adopts induction coils and is installed in a groove buried in the ground. The ground is cut to 20 cm and buried to form a loop. The antenna needs to be protected by a PVC pipe to prevent water ingress from corroding the antenna.

　　2) Dual-frequency electronic tags are placed on vehicles entering and exiting the parking lot to identify the vehicles. For entering and exiting the parking lot, parking space detection and intelligent guidance and reverse car search services are performed.

　　3) The 2.4G card reader performs full coverage of the signal, receives the data sent by the tag in real time, and installs it at the entrance and exit of the vehicle, about 1.5M above the ground, to ensure that it can cover the area of the low-frequency activator coil antenna to ensure the data Read
