Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] Such as figure 1 As shown, the present invention proposes a multi-area scalable RFID system based on the CAN bus, including: one RFID main area subsystem A01 and multiple RFID extended area subsystems A03, and the subsystems are connected through the expansion interface A02.

[0044] Such as figure 2 As shown, the RFID main area subsystem A01 includes seven major components:

[0045] B01. The main control MCU is responsible for receiving and responding to the external commands of the RFID system, sending commands to the RFID reading and writing unit and receiving the returned tag informat...

Abstract

The invention belongs to the field of radio frequency identification and relates to a multi-area expandable RFID system based on a CAN bus, which is characterized in that the system comprises an RFIDmain area subsystem and a plurality of RFID expansion area subsystems. The RFID main area subsystem includes an RFID read / write unit, a master control MCU, an RF control unit, a CAN bus transceiver unit, a plurality of read-write antennas, and a plurality of expansion output interfaces. The RFID expansion area subsystem includes an auxiliary MCU, a radio frequency control unit, a CAN bus transceiver unit, a plurality of read-write antennas, an expansion input interface and an expansion output interface. The RFID primary area subsystem is interconnected with the extended area subsystem and theextended area subsystem only through the extended interface. The invention only uses one RFID read-write unit, realizes the RFID multi-area read-write ability through a simple expansion interface, supports the serial and star expansion of the read-write area, and can be widely used in the cost-sensitive multi-RFID read-write area.

Description

technical field [0001] The invention relates to the field of radio frequency identification, in particular to a CAN bus-based multi-region expandable RFID system. Background technique [0002] Radio Frequency Identification (RFID, Radio Frequency Identification) is a communication technology that can identify specific targets through radio signals and read and write related data without the need to establish mechanical or optical contact between the identification system and specific targets. It has non-contact, non-line-of-sight , anti-interference, large capacity and other advantages. RFID technology originated in the United Kingdom and was used in World War II to identify enemy and enemy aircraft. It was commercially used in the 1960s. With the advancement of technology, RFID is widely used in logistics and supply management, manufacturing and assembly, air baggage handling, mail / express package processing, document tracking / library management, animal identification, spo...
