Patent ID: 8694029

Claim:
A method for monitoring entities moving in a monitored space represented by a first digital model comprising a set of maps with different levels of granularity representing a fineness of the requested monitoring, each map being divided into geographical zones of a predetermined shape, and having a size defined according to the level of granularity, the method including: an identification step for identifying geographical zones of each map in the form of a complete address, so as to identify each geographical zone uniquely, a definition step for defining operational zones and associating each operational zone with a predefined level of granularity, a configuration step for loading a set of data relative to the geographical zones associated with the maps of different levels of granularity, and with the operational zones, a positioning step for positioning the entity, so as to determine the geographical coordinates of the monitored entity, a first determination step for determining a level of granularity to be applied, as a function of the geographical coordinates of the monitored entity a second determination step for determining a geographical zone, from a map with the predetermined level of granularity, containing the entity, a detection step for detecting a change of zone as a function of the geographical coordinates of the monitored entity, the monitored entity either going from an original geographical zone to a destination geographical zone without changing operational zones, or from an original operational zone to a destination operational zone, and an application step for applying a new level of granularity as a function of the operational destination zone, in the case of a change of operational zone, wherein the first and second determination steps, the detection step, and the application step are carried out within each entity, independently, without outside communications.
