The invention provides a transregional equipment positioning method, system and device, and a medium. The method comprises the following steps: positioning area judgment, that is, judging whether equipment is located in a first area or a second area, proceeding to first area positioning if it is determined that the equipment is located in the first area, and proceeding to second area positioning if it is determined that the equipment is located in the second area; the first area positioning, that is, carrying out the first area positioning on the equipment; and the second area positioning, that is, carrying out the second area positioning on the equipment. The transregional equipment positioning method, system and device and the medium provided by the invention have the advantages that thepower consumption is extremely low; intelligent work mode switching for positioning equipment can be achieved through comprehensive judgements on factors such as durations, signal intensities, etc.;and a usage period for satellite positioning is shortened, and a usage frequency for the satellite positioning is reduced, so that the power consumption of the positioning equipment can be greatly reduced.
