METHOD AND SYSTEMS FOR LOCALIZING OBJECTS USING PASSIVE RFID TAGs |
摘要 |
Method and system for localizing an object in a stack of objects. A passive radio frequency identification (RFID) tag is attached to each object. Each RFID tag includes a unique identifier of the object to which the RFID tag is attached. A RFID reader has multiple antennas. Each antenna is positioned to transmit a signal that can be detected by different RFID tags attached to the objects within a reading range of the transmitted signal from each antenna. The antennas are sequentially selected and powered to transmit to the stack a read signal including object's identifier for the object to be localized. If a response to the read signal is received by a selected and powered antenna from a RFID tag that matched the object's identifier with its unique identifier, then a light emitting diode (LED) is lighted to identify a location of the object being localized.
