METHOD AND APPARATUS FOR LOCATING AND TRACKING OBJECTS IN A MINING ENVIRONMENT |
摘要 |
Methods and apparatus for locating and tracking objects in a mining environment are disclosed that include selecting an operational area within which the locations of a plurality of objects are to be determined and tracked over time. Radio transceiver systems and associated display systems provided to the plurality objects are operated to form an ad-hoc, peer-to-peer network. The relative positions of the various objects are determined by measuring the time-of-flight of radio signals exchanged between various ones of the radio transceiver systems and analyzing the time-of-flight of such exchanged radio signals. The relative positions of at least some of the objects within the operational area are then displayed on the display system.
