Description

L'invention concerne les courses cyclistes. Un coefficient allant de 1 à 10 permet d'indiquer au public la difficulté du parcours sur lequel se déroule la course. Ce coefficient de difficulté provient d'un calcul sur des paramètres physiques qui sont mesurés à l'aide de capteurs embarqués dans un véhicule qui emprunte le parcours de la course.The invention relates to bicycle races. A coefficient ranging from 1 to 10 makes it possible to indicate to the public the difficulty of the course on which the race is taking place. This coefficient of difficulty comes from a calculation on physical parameters that are measured using sensors embedded in a vehicle that follows the course of the race.

Les courses cyclistes se pratiquent sur des routes sur lesquelles la circulation est momentanément interdite aux autres usagers. Le public ne se rend pas toujours compte de la difficulté de la course. Cette difficulté peut provenir de l'état du revêtement de la route, de la pente montante ou descendante, des conditions météorologiques telles que le vent favorable ou défavorable, pluie ou temps sec, chaleur ou froid.Cycling races are practiced on roads on which traffic is temporarily prohibited to other users. The public is not always aware of the difficulty of the race. This difficulty may arise from the condition of the road surface, the rising or falling slope, weather conditions such as favorable or unfavorable wind, rain or dry weather, heat or cold.

Il est impossible de comparer les performances des coureurs sur une même course d'une année sur l'autre si on ne connait pas ce coefficient de difficulté. Le dispositif selon l'invention permet donc de réaliser un coefficient de difficulté d'une course cycliste, compréhensible par le public, allant de 1 à 10. Il est entendu que ce coefficient provient d'un calcul effectué sur différents paramètres mesurés pendant la course et le résultat doit être fourni au public dans un délai très court pouvant aller de points de mesures espacés de 10 mètres au plus court et à 100 mètres au plus long sur le parcours de la course cycliste. Les composants suivants sont mis en oeuvre : Sur un véhicule qui roule pendant la course cycliste. 20 - Un dispositif météorologique comprenant : -Un capteur de vent à ultra-sons qui mesure la vitesse, la direction et la force du vent. -Un capteur qui mesure la température. - Un capteur qui mesure l'humidité de l'air. 25 - Un capteur mesure la pression atmosphérique qui par rapport à une référence d'altitude connue donne l'altitude du lieu. On calcule ainsi la pente montante ou descendante du lieu. - Un dispositif issu de la prise diagnostique du véhicule qui mesure la distance parcourue depuis le départ ainsi que la vitesse du véhicule. -2- - Un capteur mesure les vibrations sur la roue avant gauche démunie de suspension. On peut connaitre ainsi la qualité du revêtement de la route. - Un capteur mesure les vibrations sur la roue avant droite démunie de suspension. On peut connaître ainsi la qualité du revêtement de la route. - Un GPS, de type EGNOS par exemple, donne l'altitude et le positionnement géographique du véhicule sur la carte du parcours où s'effectue la course cycliste. On calcule ainsi la pente montante ou descendante du lieu. - Un microcontrôleur stocke les mesures effectuées. Par calcul sur les éléments mesurés il fabrique le coefficient de difficulté allant de 1 à 10 qui est mis dans une mémoire. Cette 10 mémoire peut être utilisée instantanément ou à la demande. Le résultat du coefficient de difficulté allant de 1 à 10 est affiché sur un afficheur à cristaux liquides. - Un émetteur radio qui permet l'envoi du coefficient de difficulté allant de 1 à 10 pour informer le public par l'intermédiaire de différents médias. Les dessins annexés illustrent l'invention : 15 La figure 1 représente les différents composants installés sur le véhicule. La figure 2 représente un détail de la modification apportée sur le véhicule. Sur la figure 1 on a représenté le dispositif de mesure des événements météorologiques (1), relié électriquement au microcontrôleur (5). Un capteur mesure la pression atmosphérique (3) qui par rapport à une référence d'altitude connue donne l'altitude du lieu. On calcule 20 ainsi la pente montante ou descendante du lieu, relié électriquement au microcontrôleur (5).Un dispositif mesure la vitesse et la distance parcourue, issu de la prise diagnostique du véhicule (6), relié électriquement au microcontrôleur (5). Un dispositif mesure l'altitude et le positionnement géographique du véhicule (4), relié électriquement au microcontrôleur (5). Un dispositif permet l'envoi du coefficient de difficulté allant de 1 à 10 par émetteur 25 radio (2), relié électriquement au microcontrôleur (5). Un dispositif microcontrôleur (5) qui permet de stocker les mesures effectuées, par calcul sur les éléments mesurés il fabrique le coefficient de difficulté allant de 1 à 10 qui est mis dans une mémoire. Les pneumatiques (7) des quatre roues du véhicule sont sur gonflés de manière à ne pas amortir les vibrations de roulage du véhicule. -3- Sur la figure 2 on a représenté de manière simplifiée la modification apportée à la suspension d'origine des roues avant du véhicule. Le ressort (8) est laissé tel quel alors que l'amortisseur (10) est désolidarisé du châssis du véhicule. Un capteur (9) de type accéléromètre vertical, choisi en fonction du véhicule, est fixé sur le support de la suspension, il est relié électriquement au microcontrôleur (5). Il peut être envisagé de choisir des composants électroniques de valeurs sensiblement améliorées en fonction de l'état de la technique du moment, sans modifier pour autant l'agencement des composants de cette réalisation. Par extension on peut imaginer d'autres applications sur des courses autres que cyclistes.It is impossible to compare the performance of the riders on the same race from one year to the next if we do not know this coefficient of difficulty. The device according to the invention therefore makes it possible to achieve a difficulty coefficient of a race, understandable by the public, ranging from 1 to 10. It is understood that this coefficient comes from a calculation made on various parameters measured during the race. and the result must be provided to the public in a very short time, ranging from measurement points spaced 10 meters shortest and 100 meters longest on the course of the cycling race. The following components are used: On a vehicle that rolls during the cycling race. 20 - A meteorological device comprising: - An ultrasonic wind sensor which measures the speed, direction and strength of the wind. -A sensor that measures the temperature. - A sensor that measures the humidity of the air. 25 - A sensor measures the atmospheric pressure which relative to a known altitude reference gives the altitude of the place. This calculates the rising or falling slope of the place. - A device from the diagnostic test of the vehicle that measures the distance traveled from the start and the speed of the vehicle. -2- - A sensor measures vibrations on the left front wheel with no suspension. We can thus know the quality of the pavement of the road. - A sensor measures vibrations on the right front wheel with no suspension. One can thus know the quality of the pavement of the road. - A GPS, eg EGNOS, gives the altitude and the geographical position of the vehicle on the map of the route where the cycling race is taking place. This calculates the rising or falling slope of the place. - A microcontroller stores the measurements made. By calculation on the measured elements it manufactures the coefficient of difficulty ranging from 1 to 10 which is put in a memory. This memory can be used instantaneously or on demand. The result of the difficulty coefficient ranging from 1 to 10 is displayed on a liquid crystal display. - A radio transmitter that allows sending the difficulty coefficient ranging from 1 to 10 to inform the public through various media. The accompanying drawings illustrate the invention: FIG. 1 shows the various components installed on the vehicle. Figure 2 shows a detail of the modification made to the vehicle. FIG. 1 shows the meteorological event measuring device (1) electrically connected to the microcontroller (5). A sensor measures the atmospheric pressure (3) which relative to a known altitude reference gives the altitude of the place. Thus, the upward or downward slope of the locus is calculated, electrically connected to the microcontroller (5). A device measures the speed and the distance traveled, coming from the diagnostic socket of the vehicle (6), electrically connected to the microcontroller (5). A device measures the altitude and the geographical position of the vehicle (4), electrically connected to the microcontroller (5). A device makes it possible to send the difficulty coefficient ranging from 1 to 10 per radio transmitter (2), electrically connected to the microcontroller (5). A microcontroller device (5) which stores the measurements made by calculation on the measured elements makes the difficulty coefficient ranging from 1 to 10 which is put in a memory. The tires (7) of the four wheels of the vehicle are inflated so as not to dampen the running vibrations of the vehicle. FIG. 2 is a simplified representation of the modification made to the original suspension of the front wheels of the vehicle. The spring (8) is left as is while the damper (10) is disengaged from the chassis of the vehicle. A sensor (9) of vertical accelerometer type, chosen according to the vehicle, is fixed on the support of the suspension, it is electrically connected to the microcontroller (5). It may be envisaged to choose electronic components of substantially improved values according to the state of the art of the moment, without changing the arrangement of the components of this embodiment. By extension we can imagine other applications on races other than cyclists.
