Abstract

The telephone is linked with a satellite location system. An automatic orientation device acts on an antenna (3) of the system. Negative or positive acceleration undergone by the system is measured. An antenna support moves through an angle of 180 degrees . The support orients itself based upon gravity so as to give maximum antenna gain. The antenna support moves within a sphere (7) and is held by two cylindrical coins (9). A stop (10) limits the movement of the support to 180 degrees and allows a lower cylinder to bypass a cable opening.

Description

L'invention concerne un système portable d'appel urgent comprenant un téléphone sans fil et un système de repérage par satellite.A portable emergency call system includes a cordless telephone and a satellite tracking system.

Certains brevets sont relatifs au repérage de véhicule en cas d'incident ou d'accident, le brevet DE 4421568 décrit un système avec un téléphone sans fil couplé à un système de localisation GPS. Lorsqu'un capteur de décélération détecte une collision, le système transmet un message et les coordonnées du lieu éventuellement mis en mémoire.Some patents relate to vehicle tracking in the event of an incident or accident, the patent DE 4421568 describes a system with a cordless telephone coupled to a system of GPS location. When a deceleration sensor detects a collision, the system transmits a message and the coordinates of the place possibly stored.

Le brevet US 551543 comporte un téléphone sans fil, un système de repérage GPS et un microcontrôleur notamment pour l'acquisition des signaux de capteurs dont un capteur de décélération et également un déclenchement manuel de l'appel. Celui-ci transmet via un synthétiseur de parole les données recueillies du système GPS par le microcontrôleur.US Patent 551543 includes a cordless telephone, a GPS tracking system and a microcontroller especially for the acquisition of sensor signals including a deceleration and also manual triggering of the call. This transmits via a speech synthesizer the data collected from the GPS system by the microcontroller.

Le brevet EP 0679041 est relatif à un système basé sur un téléphone sans fil comportant une touche d'appel d'urgence. La position de l'appelant est déterminée soit à partir de stations du système radio-mobile, soit par une unité de repérage par satellite en liaison avec le téléphone. Le texte transmis est compressé à l'enregistrement et décompressé à la lecture.Patent EP 0679041 relates to a system based on a cordless telephone comprising an emergency call button. The position of the caller is determined either from radio-mobile system stations, either by a satellite tracking unit in conjunction with the phone. The transmitted text is compressed when saved and decompressed when reading.

Les brevets cités ne décrivent rien en ce qui concerne la réception du signal du système de localisation par satellite. Dans le cas du GPS avec une antenne plate, celle-ci doit être orientée au zénith avec une bonne précision pour recevoir correctement les signaux des différents satellites. Certes les deux premiers brevets concernent les automobiles, qui ne posent pas de problème si elles restent dans une position normale. Pour le troisième brevet bien qu'il décrive un système portable rien n'est prévu pour le système de localisation par satellite. Dans les brevets mentionnés pour le déclenchement automatique de l'appel, les systèmes utilisent le capteur de décélération de l'air-bag ou celui de la ceinture de sécurité.The cited patents describe nothing with regard to signal reception from the signaling system. satellite location. In the case of GPS with a flat antenna, this must be oriented at the zenith with good precision to correctly receive signals from different satellites. Certainly the first two patents relate to automobiles, which do not no problem if they stay in a normal position. For the third patent although it describes a portable system, nothing is provided for the location system by satellite. In the patents mentioned for the automatic triggering of the call, the systems use the airbag or seat belt deceleration sensor.

Un système portable d'appel urgent doit pouvoir être embarqué sur une moto ou une bicyclette ou mis dans un sac à dos pour une randonnée pédestre par exemple en montagne, ce qui implique une position éventuellement non optimale pour le système de repérage par satellite, puisque demain les radio-communications seront relayées par satellite, s'affranchissant ainsi des questions de couverture de territoire par les relais terrestres.A portable emergency call system must be capable of being carried on a motorcycle or bicycle or put in a backpack for hiking, for example in the mountains, which implies a possibly non-optimal position for the tracking system by satellite, since tomorrow radio communications will be relayed by satellite, thus freeing itself from questions of territory coverage by land relays.

La présente invention remédie aux inconvénients mentionnés.The present invention overcomes the drawbacks mentioned.

Selon l'invention le système portable d'appel urgent pour radio-mobile composé d'un téléphone sans fil, interfacé avec un système de repérage par satellite est caractérisé en ce qu'il comporte un dispositif automatique d'orientation de l'antenne du système de repérage dans la position lui donnant le gain maximum, d'un dispositif de mesure de l'accélération positive ou négative subit par le système et d'un photogénérateur pour recharger les batteries.According to the invention the portable urgent call system for radio-mobile composed of a cordless telephone interfaced with a satellite tracking system is characterized in that that it includes an automatic device for orienting the antenna of the tracking system in the position giving it the maximum gain, of an acceleration measurement device positive or negative suffered by the system and a photogenerator to recharge the batteries.

La figure 1 des dessins annexés représente un système d'appel d'urgence.Figure 1 of the accompanying drawings shows an emergency call system.

La figure 2 une vue du dispositif d'orientation automatique.Figure 2 a view of the automatic orientation device.

Le système d'appel urgent (figure 1) est composé d'un téléphone sans fil (1), d'un ensemble (2) comprenant un système de repérage par satellites, de traitement de l'information et d'interfaçage comme par exemple celui décrit dans le brevet US 5515043, d'un dispositif automatique d'orientation d'antenne (3) du système de repérage par satellite, d'un dispositif de mesure de l'accélération (4) avec des capteurs (6) selon trois directions orthogonales, et d'un photogénérateur (5).The emergency call system (Figure 1) consists of a cordless telephone (1), a assembly (2) comprising a satellite tracking system, processing of information and interfacing, such as that described in US patent 5515043, an automatic antenna orientation device (3) of the satellite tracking system, an acceleration measuring device (4) with sensors (6) in three directions orthogonal, and a photogenerator (5).

Le dispositif d'orientation automatique d'antenne est constitué pour que le support d'antenne se déplace angulairement de 180° dans tous les plans et s'oriente par gravité dans le plan donnant le gain maximum de l'antenne. Une sphère (7) dans laquelle se déplace le support d'antenne (8) de forme circulaire et d'un diamètre inférieur à celui de la sphère. Le diamètre inférieur est nécessaire pour d'une part obtenir un mouvement angulaire suffisant et d'autre part pour permettre le passage du câble d'antenne. Le support d'antenne est tenu par deux pièces cylindriques (9) de chaque côté de celui-ci, disposées l'un en face de l'autre. La base des cylindres est fixée sur le support d'antenne ou d'un côté sur l'antenne s'il s'agit d'une antenne plate, et le sommet peut être de deux formes. Soit il est hémisphérique, dans ce cas les matériaux de la sphère et du cylindre doivent avoir entre eux un bon coefficient de frottement pour permettre un glissement sans contrainte, avec une usure normale en absence de lubrifiant, soit le sommet est équipé d'une bille. Une butée de forme cylindrique (10) dont la hauteur est compatible avec le diamètre du support d'antenne limite le mouvement du support d'antenne à 180° et permet au cylindre inférieur de contourner l'orifice (11) du câble d'antenne.The automatic antenna orientation device is formed so that the support antenna moves angularly 180 ° in all planes and is oriented by gravity in the plane giving the maximum gain of the antenna. A sphere (7) in which the antenna support (8) of circular shape and of a diameter smaller than that of the sphere. The smaller diameter is necessary on the one hand to obtain sufficient angular movement and on the other hand to allow the passage of the antenna cable. The antenna support is held by two cylindrical pieces (9) on each side thereof, arranged one opposite the other. The base of the cylinders is fixed on the antenna support or on one side on the antenna if it is a flat antenna, and the top can be of two shapes. Either it is hemispherical, in this case the materials of the sphere and the cylinder must have a good coefficient of friction to allow sliding without constraint, with wear normal in the absence of lubricant, or the top is equipped with a ball. A form stop cylindrical (10) whose height is compatible with the diameter of the limiting antenna support the movement of the antenna support at 180 ° and allows the lower cylinder to bypass the opening (11) of the antenna cable.

En position normale d'utilisation, on équilibre le support de sorte que son orientation donne le gain maximum à l'antenne. Celle-ci conserve cette orientation quelle que soit la position spatiale du système d'appel. Un rappel du câble d'antenne peut être utilisé de sorte qu'il ne soit pas un obstacle au mouvement du support d'antenne.In normal position of use, the support is balanced so that its orientation gives the maximum gain at the antenna. This retains this orientation whatever the position spatial of the calling system. An antenna cable recall can be used so that it does not is not an obstacle to the movement of the antenna support.

Par exemple, une antenne plate (12) peut être installée sur le support d'antenne. Celle-ci, accordée sur 1 575 MHz, la fréquence standard (code S) du GPS, doit être orientée au zenith pour obtenir un gain maximum.For example, a flat antenna (12) can be installed on the antenna support. This one, tuned to 1,575 MHz, the standard frequency (code S) of the GPS, must be oriented zenith for maximum gain.

Le dispositif de mesure de l'accélération (4) est composé d'un cube sur lequel est disposé un capteur (6) sur chacune des trois faces orthogonales générant un signal électrique proportionnel à l'accélération positive ou négative subie par le système d'appel. Un réglage du seuil de déclenchement à partir duquel le système d'appel transmet un message et les coordonnées du lieu comme il est indiqué dans les brevets mentionnés ci-dessus, peut être sous deux formes. Soit par un bouton, par exemple rotatif, avec un index gradué, soit l'utilisateur compose la valeur sur le clavier du téléphone qui se trouve dans le mode de fonctionnement adéquat.The acceleration measurement device (4) consists of a cube on which is placed a sensor (6) on each of the three orthogonal faces generating an electrical signal proportional to the positive or negative acceleration suffered by the call system. A trigger threshold setting from which the calling system transmits a message and contact details of the place as indicated in the patents mentioned above, can be in two forms. Either by a button, for example rotary, with an index graduated, or the user dials the value on the telephone keypad located in the adequate mode of operation.

Le système de traitement de l'information calcule l'amplitude de l'accélération à partir des trois vecteurs représentés par le signal des trois capteurs.The information processing system calculates the amplitude of the acceleration from the three vectors represented by the signal from the three sensors.
