Rfid tag pairing method, apparatus, and application method

A Radio Frequency Identification (RFID) tag pairing apparatus, comprising:

• a reader-writer, a plurality of master tags, and a plurality of slave tags, wherein each of the plurality of master tags is physically connected to one of the plurality of slave tags;
• the reader-writer is configured to:
• transmit, by each master tag, a pairing signal to a corresponding slave tag, wherein the slave tag is a tag physically connected to the master tag;
• and
• perform traversal to obtain master tag information and slave tag information, and pair the master tag and the slave tag that return the tag information in a same communication time slot, wherein the master tag and the corresponding slave tag communicate with the reader-writer in the same communication time slot in a temporal collaboration manner.

An application method for a Radio Frequency Identification (RFID) tag pairing apparatus, comprising:

• respectively attaching master tags and slave tags to network ports and network cables, wherein there are several network ports and several network cables;
• respectively physically connecting the master tags and the slaves on the corresponding network ports and network cables;
• transmitting, by a reader-writer, a pairing signal through each master tag, to a corresponding slave tag, wherein the slave tag is a tag physically connected to the master tag, and the pairing signal is a level handshake signal which the master tag transmits to the slave tag through a physical connection;
• performing traversal, by the reader-writer, to obtain master tag information and slave tag information, and pairing the master tag and the slave tag that return the tag information in a same communication time slot to obtain pairing information, wherein the master tag and the corresponding slave tag communicate with the reader-writer in the same communication time slot in a temporal collaboration manner;
• and
• determining a pairing relationship between the network ports and the network cables according to the pairing information.
