Title
(EN) PASSIVE INFRARED SENSOR SYSTEM FOR POSITION DETECTION
(FR) SYSTÈME DE CAPTEURS PASSIFS À INFRAROUGE POUR DÉTECTION DE POSITION
Abstract
(EN)
According to the invention, a PIR sensor system (100) comprises a first PIR sensor (1) associated with a first sensing region (11) and a second PIR sensor (2) associated with a second sensing region (12). The first and second sensing regions partially overlap and are divided into detection cells (46a- 46f) and (45a- 45d). Each detection cell is represented by predetermined characteristics of first and second output signals, which signals are based on input signals from first and second sensing elements (4-7) of each PIR sensor. Thereby different detection cells are encoded by a certain combination of signal characteristics (amplitude and sign) of the first and second output signals. Further, the PIR sensor system comprises a processing unit (15) configured to associate the characteristics of the first and second output signals with one of the detection cells for determining in which of the detection cells a heat source is positioned. The invention is advantageous in that production costs of the PIR sensor system are reduced. A calibration method for identifying the correspondence between the detection cells and the output signals at installation is also provided.

L'invention concerne un système de capteur PIR (100) comprenant un premier capteur PIR (1) associé à une première région de détection (11) et un second capteur PIR (2) associé à une deuxième région de détection (12). Les première et deuxième régions de détection se chevauchent partiellement et sont divisées en cellules de détection (46a- 46f) et (45a- 45d). Chaque cellule de détection est représentée par des caractéristiques prédéterminées de premier et second signaux de sortie, ces signaux étant basés sur des signaux d'entrée à partir de premier et second éléments de détection (4-7) de chaque capteur PIR. Ainsi, différentes cellules de détection sont codées par une certaine combinaison de caractéristiques de signal (amplitude et signe) des premier et second signaux de sortie. En outre, le système de capteurs PIR comprend une unité de traitement (15) configurée pour associer les caractéristiques des premier et second signaux de sortie avec l'une des cellules de détection afin de déterminer dans laquelle des cellules de détection une source de chaleur est positionnée. L'invention est avantageuse en ce que les coûts de production du système de capteurs PIR sont réduits. L'invention concerne également un procédé d'étalonnage pour identifier la correspondance entre les cellules de détection et les signaux de sortie lors de l'installation.
