Abstract
A method for operating a wireless-based monitoring system of a transportation vehicle, wherein tag units are held in the transportation vehicle by a respective retention device and each retention device includes a mechanical encoding through which a spatial orientation of the held tag unit is specified. Each tag unit determines its spatial orientation and its characteristic position in the transportation vehicle by its own position sensor apparatus, and each tag unit repeatedly captures a distance from at least one predetermined object by its own distance measuring apparatus, and the central control unit determines a respective object position of the at least one object based on the respective characteristic position of the tag units and of the distances signaled respectively by these tag units and controls at least one predetermined security function in the transportation vehicle.
