RFID INTERROGATOR HAVING COLLISION TYPE IDENTIFICATION FUNCTION AND CONTROL METHOD THEREOF |
摘要 |
Disclosed is an RFID interrogator having a collision type identification function and a control method thereof. It verifies whether or not a collision occurs in a received signal by analyzing data of a signal received from an RF communication unit and performs a corresponding collision resolution operation by diagnosing a collision type in accordance with a collision generation means between the corresponding RFID interrogator and other interrogators or a tag. Since all types of collisions that occur between the RFID interrogator and the tag can be identified, a reason for occurrence of the collisions can be rapidly recognized to cope with the reason for the collisions.
