SYSTEM FOR TRACKING A PRESENCE OF PERSONS IN A BUILDING, A METHOD AND A COMPUTER PROGRAM PRODUCT
First Claim
1. A system for tracking a presence of persons in a building, comprising:
- a sensor network including;
a motion sensor for sensing a person'"'"'s motion in a room of the building,a localization sensor for sensing if a person is present at a particular location in the room, anda computer system that is communicately connected to the sensor network, wherein the computer system further includes a processor that is arranged for generating a presence state vector indicating a presence probability value of a person in the room, based on sensor information provided by the sensor network, and wherein the presence state vector is further based on information of interconnection structures between adjacent rooms in a floor plan of the building.

Abstract
A system for tracking a presence of persons in a building, a method and a computer program product Abstract The invention relates to a system for tracking a presence of persons in a building. The system comprises a sensor network a computer system that is communicately connected to the sensor network. The sensor network includes a motion sensor for sensing a person'"'"'s motion in a room of the building, a door sensor for sensing if a door of the room is opened and/or closed, and a localization sensor for sensing if a person is present at a particular location in the room. Further, the computer system includes a processor is arranged for generating a presence state vector indicating a presence probability value of a person in the room, based on sensor information provided by the sensor network.
