Abstract

The present invention can be used to automatically determine the measurement of a long jump while calculating the position of the take-off foot on the take-off board and the length of the run-up. The system comprises two transmitter modules, two receiver modules and a run-up module. The transmitters bombard the receivers with pulsed infrared photoelectric rays. Each ray has a scale of 1 cm. When the athlete places his or her foot in front of the run-up module, the run-up distance is automatically calculated and displayed. Next, as soon as the jumper places his or her foot on the take-off board, i.e. between the first two modules (transmitter-receiver), infrared micro-barriers are interrupted and the exact measurement of the position of the end of the foot is displayed on the receiver module or on a remote screen. If the foot is placed on the prohibited area, a beep and a voice signal are sounded (foot fault); the fault distance is displayed. If the jump is valid (no beep), when the athlete lands, the measurement of his or her jump is automatically displayed on the scaled receiver on the screen. This system can be used in athletics for long jump training. In competition, the system can replace or assist the chief judge.

Description

Titre de l'invention : SYSTÈME AUTOMATIQUE DE MESURE ET DE  Title of the invention: AUTOMATIC SYSTEM OF MEASUREMENT AND
VALIDATION DES SAUTS HORIZONTAUX  VALIDATION OF HORIZONTAL HOPPING
CONTEXTE DE L’INVENTION BACKGROUND OF THE INVENTION
En athlétisme les sauts horizontaux (saut en longueur et triple saut) sedéroulent comme suit :  In athletics the horizontal jumps (long jump and triple jump) are as follows:
-le sauteur est appelé et a un temps déterminé pour exécuter son effort. -l’athlète pose son pied sur une marque sous la forme d’une bande adhésivecollée sur la piste. (la marque est le début de la course d’élan, cette dernière est très précises les foulées sont comptées pour arriver sur la planche de façon optimale sans que le pied d’impulsion ne touche la zone interdite)il s’élance et après une course rythmée il pose son pied sur une planche, exécute sa technique et s’envolepour atterrir dans le sable. La planche poséedans la largeur de la piste d’élan, la planche a une largeur de 30cm. (un athlète peut prendre son impulsion dans les premiers 20cm de la planche, mais s’il touche la zone définie par les dix derniers centimètres ou après ,1e saut est invalide)  -the jumper is called and has a determined time to execute his effort. the athlete places his foot on a mark in the form of an adhesive strip stuck on the track. (the mark is the beginning of the run-up, the latter is very precise strides are counted to arrive on the board optimally without the foot of impulse does not touch the forbidden zone) he rushes and after a rhythmic race he puts his foot on a board, performs his technique and flies to land in the sand. The board laid in the width of the runway, the board has a width of 30cm. (an athlete can take his impetus in the first 20cm of the board, but if he touches the zone defined by the last ten centimeters or after, the jump is invalid)
Généralement deux juges sont assis de part et d’autres de la planche pour regarder l’endroit où le sauteur pose son pied. Si le juge lève un drapeau rouge le saut est invalide, au contraire le drapeau blanc signifie que le saut est valide et peut être mesure .A noter que le saut est valide même si l’athlète prend l’impulsion avant la planche. Usually two judges sit on either side of the board to watch where the jumper places his foot. If the judge raises a red flag the jump is invalid, on the contrary the white flag means that the jump is valid and can be measured. Note that the jump is valid even if the athlete takes the impulse before the board.
Pour mesurer le saut, un juge identifie grâce à son œil entraîne le point d’impact de l’athlète, plante un piquet et la mesure se fait soit en déroulant un décamètre du point d’impact a la zone permise d’impulsion(au centimètre près ) soit en utilisant le système des géomètres constitue d’un prisme qu’on plante au début de l’empreinte laissée par l’impact et l’unité de mesure qui exploite le rayon réfléchie par le prisme. To measure the jump, a judge identified by his eye leads to the point of impact of the athlete, plants a stake and the measurement is done either by rolling a decametre from the point of impact to the permitted area of impulse (at centimeter) or using the surveyors' system is a prism that is planted at the beginning of the footprint left by the impact and unit of measurement that exploits the ray reflected by the prism.
L’athlète ne sait pas où il pose le pied, généralement son entraîneur au loin essaye de regarder pour des éventuels réglages .Car prendre impulsion loin de la planche vous pénalise au niveau de la mesure, et en cas de morsure il faut rectifier la course d’élan, le sauteur ayant un nombre limité d’essaies. The athlete does not know where he is putting his foot, usually his trainer in the distance tries to look for possible adjustments. To take impulse away from the board penalizes you at the level of the measure, and in case of bite must be rectified the race momentum, the jumper having a limited number of tries.
A l’entrainement la course d’élan est réglée de manière empirique (par observation des foulées)car pas d’instruments permettant de régler la course d’élan, de déterminer la pose du pied d’impulsion et en mêmetemps de mesurer automatiquement le saut. Seul l’œil de l’entraineur sert pour la plupart du temps à la préparation du sauteur. At the training, the run-up is regulated empirically (by observing the stride) because there are no instruments to adjust the momentum, to determine the pose of the foot pulse and same time to automatically measure the jump. Only the eye of the coach is used for the most part to prepare the jumper.
Les sauteurs ont des problèmes pour s’entraîner seuls, il faut toujours quelqu’un pour observer l’endroit de la pose du pied d’impulsion sur la planche. Celle-ci est trèspetite (20cm) et 10cm interdite. L’athlète doit donc réglerprécisément ses foulées pour que la dernière arrive pile sur la planche. En courant à toute vitesse c’est difficile de voir ou l’on pose le pied. Età l’entrainement les sauteurs exécutent beaucoup de sauts et il est fastidieux de mesurer avec un décamètre ou un appareil de géomètre. The jumpers have problems to train alone, you always need someone to observe the place of the pose of the pulse foot on the board. This one is very small (20cm) and 10cm forbidden. The athlete must precisely adjust his stride so that the last arrives right on the board. Running at full speed is hard to see where you put your foot. And at the training jumpers perform a lot of jumps and it is tedious to measure with a decameter or surveying machine.
L’autre problème en compétition, il y asouvent jusqu’à 24 sauteurs sur un mêmesautoir, chacun ayant sa marque au sol (ca prête à confusion)et la distance d’élan est mesurée par les athlètes en comptant les pieds l’un après l’autre.  The other problem in competition, there are as many as 24 jumpers on the same hall, each having its mark on the ground (it is confusing) and the distance of momentum is measured by the athletes counting the feet one after the other.
ETAT TECHNIQUE ACTUEL CURRENT TECHNICAL STATUS
Pour mesurer un saut horizontal actuellement l’IAAF ou les différentes fédérations disposent de deux méthodes : To measure a horizontal jump currently the IAAF or the various federations have two methods:
Le décamètreet deux juges qui observent l’endroit où l’athlète pose le pieds .S’il prend impulsion dans les premiers 20cm ou avant la planche, dès son atterrissage le drapeau blanc est levé et le saut est mesure à partir de la dernière partie du corps de l’athlète qui touche le sable, où la marque qu’a fait le corps de l’athlète a l’impact est analyse par un juge et la mesure se fait du bord de celle-ci a la fin de la planche. La mesure est lue au centimètre près et communiquée .Si la planche est mordue, le drapeau rouge est levéet le saut n’est pas mesure.  The decametrator two judges who observe the place where the athlete sets foot.If he takes impetus in the first 20cm or before the board, from his landing the white flag is raised and the jump is measured from the last part of the athlete's body touching the sand, where the mark made by the athlete's body is impacted by a judge and measured from the edge of the athlete at the end of the board . The measurement is read to the nearest centimeter and communicated. If the board is bitten, the red flag is raised and the jump is not measured.
Dans cette méthode le facteur humain intervient et peu fausser le résultat. Exemple si la planche est mal appréciée (un mordu déclaré non mordu) le résultat est faux. Si le décamètre est place à partir d’un faux impact le résultat est aussi faux. L’athlète et son coach ne savent pas exactement ou le pied a été pose pour faire des réglages et n’ont pas de base pour réclamer un saut non mordu mais déclaré comme tel. Le LASER Ivnx pro mesure de distance électronique a été approuvé par les responsables de l’athlétisme est utilisé dans les plus haut niveaux de la piste y compris les championnats du mondes et jeux olympiques. Le LASER lynx pro comprend un prisme et un pôle prisme, une liaison avec l’ordinateur pour échanger les données avec le réseau des résultats. Le pôle prisme est plante sur l’empreinte laisse par le corps et la mesure est lue sur le module lecteur et transféré sur le réseau. La méthode de calcul est la loi des cosinus dans un triangle rectangle quand l’angle du cote adjacent et l’hypoténuse sont connus, on peut trouver le cote adjacent qui représente la mesure (la précision est a 2mm près ). In this method the human factor intervenes and little distort the result. Example if the board is badly appreciated (a bitten declared not bitten) the result is false. If the decameter is placed from a false impact the result is also false. The athlete and his coach do not know exactly where the foot was laid to make adjustments and have no basis to claim a jump not bitten but declared as such. The LASER Ivnx pro electronic distance measurement has been approved by the track and field officials is used in the highest levels of the track including world championships and Olympic games. The LASER lynx pro includes a prism and prism pole, a link with the computer to exchange data with the results network. The prism pole is plant on the footprint left by the body and the measurement is read on the reader module and transferred to the network. The method of calculation is the cosine law in a right triangle when the angle of the adjacent side and the hypotenuse are known, we can find the adjacent side which represents the measurement (the accuracy is within 2mm).
Dans cette méthode il y a toujours l’inconvénient du facteur humain dans la lecture de l’endroit où l’athlète pose le pied, de même que sur l’endroit où le juge pose le pôle prisme pour lire la mesure. In this method there is always the disadvantage of the human factor in reading where the athlete sets foot, as well as where the judge places the prism pole to read the measure.
Actuellement dans le système de mesure des sauts horizontaux Currently in the system of measurement of horizontal jumps
-il n’y a pas d’aide pour calculer la course d’élan there is no help to calculate the run run
-il n’y a pas d’instruments pour déterminer automatiquement la pose du pied  there are no instruments to automatically determine the laying of the foot
-il faut des juges pour lire les mesures.  it takes judges to read the measurements.

La figurée représente la structure des micro barrières infrarouge du système .  The figurative represents the structure of the infrared micro-barriers of the system.
Pour une Barrière, le module émetteur infrarouge (5) pilote une LED lr(2) placée sur le point focal(11) de la lentille convergente(1 ),la LED émet une lumière pulsée(14).la barrière est alimentée par batterie de 9-12 volts.  For a barrier, the infrared emitter module (5) drives an LED lr (2) placed on the focal point (11) of the convergent lens (1), the LED emits a pulsed light (14) .the barrier is powered by battery 9-12 volts.
Le module récepteur de la barrière comprend le même type de lentille et reçoit les pulsations lumineuse par la LED réceptrice(3) place sur le point focal(11)la LED est reliée à un microcontrôleur pic 18f877(6) via le module récepteur infrarouge(4). L’interruption de la barrière entraîne un changement d’état de la broche du récepteur infrarouge reliée au pic qui allume les LEDS haute luminosités (9). Le pic pilote aussi un réseau émetteurradiofréquence 433mhz(8) -codeur um3750 ou autre pour l’envoie des informations sans fils. L’alimentation est assurée par une batterie 12v(13).A noter que pour tout le système, les pics sont montés en cascade pour scanner les changements d’état des broches reliées aux récepteurs infrarouge qui sont a l’état logique haut ou bas selon que la barrière est interrompue ou pas. The receiver module of the barrier comprises the same type of lens and receives the light pulsations by the receiving LED (3) placed on the focal point (11) the LED is connected to a peak microcontroller 18f877 (6) via the infrared receiver module ( 4). The interruption of the barrier causes a change of state of the pin of the infrared receiver connected to the peak which lights up the high-luminosity LEDs (9). The peak also drives a 433mhz (8) -coder um3750 or other radio-frequency transmitter network for sending wireless information. Power is supplied by a 12v battery (13). Note that for the whole system, the peaks are mounted in cascade to scan the state changes of the pins connected to the infrared receivers which are logically high or low depending on whether the barrier is interrupted or not.

FONCTIONEMENT DU SYSTEME FUNCTIONING OF THE SYSTEM
Lors d’un entrainement ou d’une compétition le système de mesure automatique des sauts est disposécomme sur le schéma de la figure 1. During a training or a competition, the system for automatic measurement of jumps is arranged as in the diagram of FIG.
175 MODE ENTRAINEMENT 175 TRAINING MODE
Dans le mode entrainement une variante du système consiste aréduire la longueur du système émetteur-récepteur de calcul. Exemple 200 LEDS qui aboutissent à 200cm mesurables. In the training mode, a variant of the system is to reduce the length of the transceiver system. Example 200 LEDs that reach 200cm measurable.
Le sauteur entre sur le clavier(17) la distance des modules de calcul par 180 rapporté la fin de la planche légale(13).Et la mesure effectuée sera déduite du calcul entre la distance lue par le système et la distance introduite(13)(par addition dans le logiciel). The jumper enters on the keyboard (17) the distance of the calculation modules by 180 reported the end of the legal board (13). And the measurement made will be deduced from the calculation between the distance read by the system and the distance introduced (13) (by addition in the software).
L’athlètepose son pied d’appel devant le module de calcul d’élan(1),le système sent le pied par la réception du signal infrarouge qui rebondit du iss pied. L’écran (2) est réinitialisé, le module ultrason émet un signal qui rebondit sur le module(8) place au début de la planche, la longueur de la course d’élan symbolisée par l’écartement entre les modules (1 ) et (8) s’affiche automatiquement sur l’écran. Le sauteur démarre sa course et arrive sur la planche de saut, son pied d’appel interrompt les barrières 190 infrarouges constituées par les modules(9) et(8) ,les LEDS graduées au centimètre s’allument pour marquer la distance d’empreinte sur la planche. Si l’empreinte se trouve dans la zone permise ou (les premiers 20cm(25) le sauteur n’entend pas de bip ou de message vocal il sait que son saut est valide. A son atterrissage les micros barrières infrarouges 195 constituées par les modules (14) et(15) sont interrompues .  The athlete puts his foot of call in front of the module of elk calculation (1), the system feels the foot by the reception of the infrared signal which bounces of iss foot. The screen (2) is reset, the ultrasound module emits a signal that bounces on the module (8) placed at the beginning of the board, the length of the run of momentum symbolized by the spacing between the modules (1) and (8) is automatically displayed on the screen. The jumper starts his race and arrives on the jump board, his call foot interrupts the infrared barriers 190 constituted by the modules (9) and (8), the LEDS graduated centimeter light up to mark the footprint distance on Plate. If the footprint is in the permitted area or (the first 20cm (25) the jumper does not hear a beep or voice message he knows that his jump is valid.At his landing infrared microphones barriers 195 constituted by the modules (14) and (15) are interrupted.
Lors du balayage effectue par les microcontrôleurs pilotant la réception infrarouge la première barrière interrompue par une partie du corps de l’athlètereprésente la mesure. Celle-ci est affichée en allumant la LED correspondante sur la graduation(18) du module (15).Le sauteur peut donc lire la mesure de son saut. During the scanning carried out by the microcontrollers controlling the infrared reception the first barrier interrupted by a part of the body of the athlete represents the measurement. This is displayed by switching on the LED corresponding on the graduation (18) of the module (15) .The jumper can read the measurement of his jump.
Si lors de la prise d’impulsion, le pied(7) de l’athlète touche la zone interdite(24) il entend un bip et un message vocal du genre "saut mordu” en français ou le même message dans toutes les langues voulues. If during impulse taking, the foot (7) of the athlete touches the prohibited zone (24) he hears a beep and a voice message of the genre "jump bitten" in French or the same message in all the desired languages .
A noter que lorsque le saut est mordu la mesure de la distance mordue s’affiche, mais le système ne calcule pas la mesure du saut. Note that when the jump is bitten the measure of the bite distance is displayed, but the system does not calculate the jump measurement.
MODE COMPETITION  COMPETITION MODE
Dans le mode compétition en plus du mode entrainement, dès que le pied(7) est pose devant le module (1 ),le dispositif(4) sur le module (1 ) est un Lecteur RFID qui identifie l’athlète en lisant le transpondeur(6)et initialise l’écran des résultats(22). L’écran affiche a dimension de l’empreinte du pied par rapport à la zone légale de saut sur la planche d’impulsion, et aussi le résultat du saut .l’écran peut comporter des sorties usb,rs232 et Bluetooth pour intégrer automatiquement les mesures valides au réseau des résultats de la compétition. A noter que dans une variante du système toute la longueur du sautoir peut être encadrée par les modules de calcul des sauts (14) et(15), la valeur introduite dans le système à travers le clavier (16) sera juste 0 cm, et la mesure déterminée par la LED allumée sur l’écran (16) et le dispositif(18).Les modules (9) et (8) peuvent aussi être allonges jusqu’au début de la course d’élan, dans cette option les points d’impact des foulées peuvent être obtenues et la course d’élan réglée de façon beaucoup plus précise. In the competition mode in addition to the training mode, as soon as the foot (7) is placed in front of the module (1), the device (4) on the module (1) is an RFID reader which identifies the athlete by reading the transponder (6) and initializes the results screen (22). The screen displays a dimension of the footprint with respect to the legal jump area on the impulse board, and also the result of the jump. The screen can include usb, rs232 and Bluetooth outputs to automatically integrate valid measurements to the network of the results of the competition. Note that in a variant of the system the entire length of the jumper can be framed by the calculation modules jumps (14) and (15), the value introduced into the system through the keyboard (16) will be just 0 cm, and the measurement determined by the LED lit on the screen (16) and the device (18). The modules (9) and (8) can also be extended until the beginning of the run-up, in this option the points stride impact can be achieved and the run run run much more accurately.
