Embodiment Construction
[0028] An RFID long-distance card reading system, please refer to figure 1 Shown, including radio frequency card, card reader, data collector. Multiple card readers can be set, and multiple radio frequency cards can be set as required.
[0029] Please also see figure 2 and image 3 As shown, they are respectively the block diagram of the hardware structure of the data collector and the card reader and the block diagram of the hardware structure of the radio frequency card in the present invention.
[0030] The data collector adopts the ARM processor, connects the card reader through the RS485 communication interface, sends relevant command operations to the card reader, analyzes and processes the read data, and also sets the information of the radio frequency card for management RF card. Run the communication protocol, send and receive command frames, data frames, management frames, manage card readers and radio frequency cards and analyze data processing. You can set th...
