System and method for tracking and monitoring personnel and equipment
A system and method are described for using RFID tags to track and monitor personnel and equipment in large environments and environments that are prone to multipath fading. The system scans the environment by selecting local interrogation zones where RFID tags may be located. Multiple antennae are used, each transmitting a portion of an activation signal, such that the activation signal will be formed in the selected local interrogation zone. Different subsets of the antennae are successively selected, each targeting the selected local interrogation zone, to repeat the activation signal for each subset of antenna. RFID tags in the local interrogation zone will receive the portions of the activation signals and process them to determine whether the full activation signal was destined for that local interrogation zone for each of the subsets of antennae. An activated RFID tag will transmit its tag information, including any data collected from sensors connected to the tag, back to the system. The systems and method will use the location information of the various RFID tags in the global environment and combine that with data received through cameras and other sensors to provide a display with the RFID tag location information superimposed. The data collected about various regions of the environment may be transmitted back to the RFID tags to provide the personnel with information about their surroundings.
