APPARATUS AND METHOD FOR TRACING POSITION BASED ON SELF ORGANIZATION MAPPING ALGORITHM

摘要

PURPOSE: A tracing position tracing apparatus based on self-organization mapping algorithm and a tracing method thereof are provided to trace a movement of a target in a space of a building by using a self-organizing map. CONSTITUTION: A tracing position tracing apparatus based on self-organization mapping algorithm comprises a plurality of access points(10), a communication unit(11), a standard position database(12), a mapping unit(13), and a tracing unit(14). The access points sense the intensity of signals at each node in a space of a building. The communication unit performs data transmission/reception operations between the access points. The standard position database stores the information about the intensity of the signals according to inner space coordinates in the building. The mapping unit constructs the standard position database by mapping the coordinates corresponding to the intensity of the signals using a self-organizing map. The tracing unit traces mobile coordinates of an active tag.
