Abstract
A position management system including two or more types of detection tags provided to objects whose positions are to be detected, detectors provided corresponding to the detection tags, and a position data processor, in which the detection tags complement detection abilities with each other, in which when a detector receives a signal from a detection tag provided to an object, the detector generates detection result data including a unique tag ID which is assigned to the detection tag and a device ID which is assigned to the detector, and in which the position data processor processes the detection result data acquired from the detector and arrangement data of the detector in order to specify a position of the object.
