La présente invention concerne un appareil de contrôle utilisable pour vérifier le fonctionnement d'un dispositif émetteur d'ondes infrarouges. The present invention relates to a monitoring device which can be used to check the operation of an infrared wave emitting device.
Il existe de nombreux dispositifs et systèmes qui utilisent une émission de lumières infrarouges comme par exemple les télécommandes, des dispositifs de repérage ou des moyens qui permettent des transits d'informations. There are many devices and systems which use an emission of infrared lights such as for example remote controls, tracking devices or means which allow information transits.
Compte-tenu du fait que la lumière infrarouge est invisible pour l'oeil humain, le contrôle du bon fonctionnement de ces dispositifs ou systèmes, s'effectue avec un matériel particulier qui n'est pas utilisable dans toutes les situations. Given the fact that infrared light is invisible to the human eye, the proper functioning of these devices or systems is checked with special equipment which cannot be used in all situations.
La présente invention propose un appareil qui permet de vérifier facilement l'émission de lumière infrarouge, sans contrainte particulière au niveau de son utilisation. The present invention provides an apparatus which makes it possible to easily verify the emission of infrared light, without any particular constraint in terms of its use.
L'appareil selon l'invention se présente sous la forme d'un boîtier de très faible dimension, de la taille d'un briquet par exemple, ce qui permet de l'avoir à disposition sur soi, en permanence, ou en tout endroit utile pour contrôler et vérifier les émetteurs de rayonnements infrarouges. The device according to the invention is in the form of a very small box, the size of a lighter for example, which makes it possible to have it available on you, permanently, or anywhere useful for controlling and verifying the emitters of infrared radiation.
Selon l'invention, cet appareil comprend : - une cellule de détection sensible à la longueur d'onde de l'émetteur ; - un dispositif d'amplification du signal, du genre transistor ; - des moyens d'affichage de la présence d'un signal ; - une alimentation électrique appropriée. According to the invention, this device comprises: - a detection cell sensitive to the wavelength of the transmitter; - a signal amplification device, of the transistor type; - means for displaying the presence of a signal; - an appropriate power supply.
Selon l'invention, la cellule de détection est constituée d'une photo diode ou photo transistor et les moyens d'affichage sont par exemple constitués d'une diode électroluminescente ou d'une lampe à filament. According to the invention, the detection cell consists of a photo diode or photo transistor and the display means consist for example of a light-emitting diode or a filament lamp.
L'invention sera encore détaillée à l'aide de la description suivante et des dessins annexés, donnés à titre indicatif, et dans lesquels : - la figure 1 représente l'appareil de contrôle selon l'invention face à un émetteur ; - la figure 2 correspond au schéma électrique de l'appareil. The invention will be further detailed with the aid of the following description and of the appended drawings, given by way of indication, and in which: - Figure 1 shows the control apparatus according to the invention facing a transmitter; - Figure 2 corresponds to the electrical diagram of the device.
L'appareil se présente sous la forme d'un boîtier de dimension modeste correspondant par exemple à la taille d'un briquet. Ce boîtier 1 renferme une ou deux piles 2 par exemple pour l'alimentation électrique des composants. A The device is in the form of a box of modest size corresponding for example to the size of a lighter. This box 1 contains one or two batteries 2 for example for the electrical supply of the components. AT
<Desc/Clms Page number 2><Desc / Clms Page number 2>
l'extrémité du boîtier, sur la face 3 en regard de l'émetteur 4, on trouve une cellule 5 de détection constituée par exemple d'une photo diode ou photo transistor. Sur le côté du boîtier c'est-à-dire la face 6, on trouve un interrupteur 7 de mise en service ou d'arrêt de l'appareil ainsi qu'un voyant 8 qui permet de signaler l'état marche ou arrêt et éventuellement l'état des piles 2. the end of the housing, on the face 3 facing the emitter 4, there is a detection cell 5 consisting for example of a photo diode or photo transistor. On the side of the housing, that is to say the face 6, there is a switch 7 for putting the device into service or stopping, as well as a light 8 which makes it possible to signal the on or off state and possibly the state of the batteries 2.
Le voyant 8 est constitué d'une diode électroluminescente de couleur verte par exemple. The indicator 8 consists of a light-emitting diode of green color for example.
Sur le dessus du boîtier, bien en vue de l'opérateur, on trouve un voyant 9 qui indique la présence ou l'absence de signal en provenance de l'émetteur 4. On the top of the box, in full view of the operator, there is an indicator light 9 which indicates the presence or absence of a signal from the transmitter 4.
Ce voyant est en forme de diode ou de lampe à filament. This indicator is in the form of a diode or a filament lamp.
L'émetteur 4 est par exemple constitué d'un dispositif quelconque renfermant une diode à rayonnement infrarouge. The emitter 4 is for example made up of any device containing an infrared radiation diode.
Le boîtier 1, à disposition d'un opérateur, permet de contrôler facilement en tout lieu, l'état de fonctionnement de l'émetteur 4, en captant le rayonnement par l'intermédiaire de la photo diode 5 par exemple. The box 1, available to an operator, makes it possible to easily control anywhere, the operating state of the transmitter 4, by capturing the radiation via the photo diode 5 for example.
La figure 2 montre le schéma électrique et les composants disposés dans le boîtier. Figure 2 shows the electrical diagram and the components arranged in the housing.
Ainsi on retrouve l'interrupteur 7 et les piles 2 qui alimentent un premier circuit constitué du voyant 8 et d'une résistance 10 en série d'une valeur de 3,3 kQ par exemple. Thus we find the switch 7 and the batteries 2 which supply a first circuit consisting of the indicator 8 and a resistor 10 in series with a value of 3.3 kQ for example.
Le second circuit, parallèle au premier, comprend-un transistor 11 du type 2N1711 qui joue le rôle d'amplificateur, - le voyant 9 de signalisation constitué d'une diode électroluminescente du type HLMPED31 et-une résistance 12 de l'ordre de 1 kQ, interposée entre les deux. The second circuit, parallel to the first, comprises a transistor 11 of the 2N1711 type which acts as an amplifier, the indicator light 9 consisting of a light-emitting diode of the HLMPED31 type and a resistor 12 of the order of 1 kQ, interposed between the two.
La cellule 5 servant à la détection des ondes infrarouges est du type EF10SD1-ST. Elle est disposée entre la base et le collecteur du transistor 11. The cell 5 used for the detection of infrared waves is of the EF10SD1-ST type. It is arranged between the base and the collector of transistor 11.
Le voyant 9 est alimenté par le transistor 11 et s'allume dès que la cellule 5 reçoit un signal infrarouge provenant de l'émetteur 4. The indicator 9 is supplied by the transistor 11 and lights up as soon as the cell 5 receives an infrared signal from the emitter 4.
