System: Interaction between RFID Reader and Tag
1. A round of operation starts with the RFID reader receiving a
Switch-on
signal from the
backbone system via Ethernet (cable) . The reader then converts the instruction to wireless
signaling, and broadcasts it via antenna RF1.
2. All tags (both types) in the coverage of the reader will receive the signaling via their receiving
antennas; after deciphering and processing the signaling, each of the tags obtains its target tag
ID and compares the ID with its own unique ID in its chip (EPC zone). If a tag whose ID is same
as the target ID, it will determine itself as the target tag and then switch on the LED on itself.
3. If the button of a tag (both types) is clicked, the tag will send a encrypted
Feedback
signal to the
reader via its transmission module. The signal is called
Feedback
because it is expected to take
place after lighting up and is prepared for sending back to activate certain following operation.
4. The reader receives the
Feedback
signal, deciphers, processes and converts it into a message,
which will then be sent to the backbone system via Ethernet.
5. The two types of the tags transmit their own working status signal (
Heartbeat
) to certain
readers at a certain time interval via their transmission modules.
6. The reader receives the
Heartbeat
signal, deciphers, processes and converts it into a message,
which would then be sent to the backbone system via Ethernet.
7. The two types of tags are designed to support full duplex communication. Above
communication 2 and 3, 2 and 5 can be carried out simultaneously; whilst 3 (press the button)
and 5(periodic heartbeat) can be carried out successively at a very short time interval.
