Abstract

The invention is composed of a transmitter 1 and its antenna 2, two take-up antennas 3 and an electronics box 4. The transmitter, connected to its antenna arranged at the location of the passage, generates an electromagnetic field whose induction is strongly increased, during a passage, at the two pick-up antennas actuated one after the other. The electronics box processes the desired data.

Description

La présente invention concerne un dispositif permettant de détecter le passage et le sens de franchissement (une porte par exemple). The present invention relates to a device for detecting the passage and the direction of crossing (a door for example).

Le dispositif selon l'invention permet, en détectant le passage et le sens de franchissement de commander intelligemment un point lumineuse, une alarme ou autres applications. The device according to the invention makes it possible, by detecting the passage and the direction of crossing, to intelligently control a light point, an alarm or other applications.

Ce dispositif se compose d'un émetteur avec son antenne, de deux antennes réceptrices et d'un boitier électronique. This device consists of a transmitter with its antenna, two receiving antennas and an electronic unit.

Selon une variante, le dispositif peut etre utilisé en détecteur de passage ou de présence et ne comporte qu'une seule antenne réceptrice. According to a variant, the device can be used as a passage or presence detector and has only one receiving antenna.

Le dessin annexé en figure 1 représente en perspective un exemple d'utilisation . selon l'invention. The attached drawing in Figure 1 shows in perspective an example of use. according to the invention.

Un émetteur (i) est raccordé à une antenne (2 disposée au sol sur le lieu de passage. La dite antenne (2) dépasse suffisamment de part et d'autre le chambranle de porte (par exemple) pour qu'au passage d'un individu il y est présence d'au moins un pied sur la surface couverte par l'antenne (2). Deux antennes réceptrices (3) et un boitier électronique (4 composent les deux détecteurs de passage. Les deux antennes réceptrices (3) sont posées sur le pourtour du chambranle de porte (par exemple), l'une coté extérieur, l'autre cote intérieur. Le rayonnement de l'antenne émettrice (2 ) vers les antennes réceptrices (3) se trouve considérablement augmenté par la présence d'un individu situé sur le passage de porte. A transmitter (i) is connected to an antenna (2 placed on the ground at the crossing point. The said antenna (2) protrudes sufficiently on either side of the door jamb (for example) so that the passage of an individual there is the presence of at least one foot on the surface covered by the antenna (2). Two receiving antennas (3) and an electronic unit (4 make up the two passage detectors. The two receiving antennas (3) are placed on the periphery of the door jamb (for example), one on the outside, the other on the inside. The radiation from the transmitting antenna (2) to the receiving antennas (3) is considerably increased by the presence of an individual located in the doorway.

Le sens de passage est déterminé par l'ordre de sollicitation des antennes réceptrices (3) solidaires du boîtier électronique (4).  The direction of passage is determined by the solicitation order of the receiving antennas (3) integral with the electronic unit (4).

Le dispositif selon l'invention est destiné aux applications domestiques et industrielles:
- commande de points lumineux par détection.The device according to the invention is intended for domestic and industrial applications:
- control of light points by detection.

- commande d'alarmes par détection. - alarm control by detection.

- controle d'accès et de présence par détection. - access and presence control by detection.

- ect...  - ect ...

Claims (3)

REVENDICATIONS i) Dispositif pour détecter le passage et le sens de franchissement caractérisé en ce qu'un émetteur (1 relié a une antenne (2) couvrant a la base une dimension suffisante du passage, influence correctement lors d'une présence ou d'un passage les deux antennes réceptrices (3 ) espaçées en fonction de l'utilisation. Les deux antennes réceptrices (3) sont reliées a un boitier électronique (4 ) qui traite les informations recherches. i) Device for detecting the passage and the direction of crossing, characterized in that a transmitter (1 connected to an antenna (2) covering at the base a sufficient dimension of the passage, influences correctly during a presence or a passage the two receiving antennas (3) spaced depending on the use.The two receiving antennas (3) are connected to an electronic unit (4) which processes the information sought. 2) Dispositif selon la revendication 1 caractérise par son utilisation en détecteur de passage ou de présence et ne comportant qu'une seule antenne réceptrice (3). 2) Device according to claim 1 characterized by its use as a passage or presence detector and comprising only a single receiving antenna (3). 3) Dispositif selon les revendications 1 ou 2 caractérisé en ce que l'émetteur peut etre le réseau électrifié (secteur 22 volts par exemple).  3) Device according to claims 1 or 2 characterized in that the transmitter can be the electrified network (22 volt sector for example).
