摘要:
A real-time method and system of determining and validating location of a relocated mobile object or person in a tracking environment in which a plurality of sensors are located are provided. The method includes modulating a first carrier signal with a first packet including a first set of data to obtain a modulated first signal. The first signal contains the first packet and has a first precision and a first range within the environment. A modulated second signal is received from at least one of the sensors including the nearest sensor. The second signal contains a second packet including a second set of data and has a second precision and a second range within the environment. The method further includes determining and validating current location of the relocated tag within the environment based on a plurality of second packets.
摘要:
A real-time method and system for locating a mobile object or person in a tracking environment with a plurality of sensors. The method includes a tracking tag attachable to a person or object. The method includes modulating a first carrier signal with a first packet including a first set of data. The method includes transmitting the signal having a first precision and range from the tag to a nearest sensor. The method further includes repeating the steps until a modulated second signal is received at the tag from the nearest sensor within a time period. The second signal contains a second packet with second set of data and has a second precision range within the environment. The second signal is received at the tag within the time period to obtain the second packet. The location of the tag is determined based on the second packet of the received second signal.
