Presence detection system and lighting system comprising such system

摘要

A presence detection system (1) for detecting a presence of an object (3), particularly a person or an animal or vehicle, within an area (5) divided in detection zones (9A;9B;9C;9D) covering the area. The system comprises a movement detection device (11A;11B;11C;11D) for detecting a movement of the object. The system further comprises an electronic processing device (13) for storing information relating to a position of the object in a zone-wise way, based on a detected movement of the object. The electronic processing device is configured for determining the presence of the object within the area based on a detected movement of the object and stored information relating to the position of the object. The system is highly sensitive and highly prevents false presence detections. The invention also relates to a method for presence detection, and a lighting system comprising the presence detection system.

主权项

1. A presence detection system for detecting a presence of an object within an area having a plurality of detection zones, the system comprising:
a movement detection device for detecting a movement of the object, and an electronic processing device for storing information relating to a position of the object in a zone-wise way, based on the movement of the object, detected by the movement detection device, wherein the electronic processing device is configured for determining, in a zone-wise way, the presence of the object within the area based on detected movement of the object and stored information relating to the position of the object, wherein the area comprises a passage, wherein the zones include a first zone covering the passage and a second zone adjacent to the first zone, and wherein, during use, the presence of the object is determined from a first moment in time when a movement in the first zone is detected and the presence is determined when a movement in one of the other zones of the area is detected, and a non-presence of the object is determined when a movement from the second zone to the first zone is detected and thereafter no movement in the first zone is detected for a predetermined period of time.
