Description

Domaine TechniqueTechnical area

La présente invention concerne le domaine des camions malaxeurs comportant une cuve agitatrice, et en particulier le domaine du suivi de livraison du contenu de la cuve agitatrice.The present invention relates to the field of mixer trucks comprising an agitating tank, and in particular to the field of monitoring delivery of the contents of the agitating tank.

Technique antérieurePrior art

Les camions malaxeurs sont utilisés pour livrer, à un site de livraison ou de déchargement, du béton fourni par un site d'élaboration ou de chargement. Les camions malaxeurs, ou camions toupies, comportent à cet effet une cuve agitatrice, ou toupie, dans laquelle est versé le béton, sur le site de chargement. La cuve agitatrice est entraînée en rotation pendant tout le trajet d'acheminement du béton jusqu'au site de déchargement afin d'éviter sa prise. Une fois le camion malaxeur arrivé sur le site de déchargement, le sens de rotation de la cuve agitatrice est inversé et le béton contenu dans la cuve agitatrice est déchargé à l'endroit souhaité.Concrete mixer trucks are used to deliver concrete supplied by a processing or loading site to a delivery or unloading site. Mixer trucks, or mixer trucks, have for this purpose an agitating tank, or mixer, in which the concrete is poured, on the loading site. The agitator tank is driven in rotation during the entire route of conveying the concrete to the unloading site in order to avoid its setting. Once the mixer truck arrives at the unloading site, the direction of rotation of the agitator tank is reversed and the concrete contained in the agitator tank is unloaded at the desired location.

Il est connu d'utiliser des systèmes de suivi de livraison du béton, avec des moyens de saisie et de communication montés sur le camion malaxeur. En particulier, les systèmes de suivi actuels sont liés au camion malaxeur, généralement au niveau du moyen d'entraînement en rotation de la cuve agitatrice, et sont paramétrés par le conducteur du camion malaxeur lors des différentes étapes de la livraison.It is known to use concrete delivery tracking systems, with input and communication means mounted on the mixer truck. In particular, current monitoring systems are linked to the mixer truck, generally at the level of the means for driving the agitator tank in rotation, and are configured by the driver of the mixer truck during the various stages of delivery.

Cependant, le fonctionnement de tels systèmes de suivi est contraignant, notamment pour les chauffeurs des camions malaxeurs pour qui l'utilisation de tels dispositifs n'est pas intuitive et qui peut différer d'un système de suivi à un autre. De plus, les camions malaxeurs n'étant pas toujours utilisés par la même société, il est également difficile de gérer les changements d'utilisateur pour un même système de suivi lié à un camion malaxeur. Enfin, de tels systèmes de suivi se sont également avérés fragiles, et en particulier peu résistants aux forts nettoyages effectués sur les camions malaxeurs.However, the operation of such monitoring systems is restrictive, in particular for drivers of mixer trucks for whom the use of such devices is not intuitive and who may differ from one monitoring system to another. In addition, the mixer trucks are not always used by the same company, it is also difficult to manage user changes for the same monitoring system linked to a mixer truck. Finally, such systems of monitoring have also proved to be fragile, and in particular not very resistant to heavy cleaning carried out on mixer trucks.

Exposé de l'inventionDisclosure of the invention

La présente invention vise à résoudre les différents problèmes techniques énoncés précédemment. La présente invention vise ainsi à proposer un dispositif de suivi de livraison d'un camion malaxeur qui a un fonctionnement aisé, dont la gestion est simplifiée pour l'utilisateur du système de suivi, et qui présente une meilleure fiabilité que les systèmes actuels. En particulier, la présente invention vise ainsi à proposer un dispositif de suivi de livraison qui améliore le suivi effectif de la livraison tout en limitant les actions à effectuer par le chauffeur du camion malaxeur.The present invention aims to solve the various technical problems mentioned above. The present invention thus aims to propose a device for monitoring the delivery of a mixer truck which is easy to operate, the management of which is simplified for the user of the monitoring system, and which has better reliability than current systems. In particular, the present invention thus aims to propose a delivery monitoring device which improves the effective monitoring of the delivery while limiting the actions to be carried out by the driver of the mixer truck.

Ainsi, selon un aspect, il est proposé un dispositif de suivi de la livraison du chargement d'un camion malaxeur comportant une cuve agitatrice, le dispositif de suivi comprenant un boitier avec :

  • au moins un gyroscope et/ou au moins un accéléromètre monté dans le boitier et fournissant des données, et
  • des moyens de fixation du boitier sur le camion malaxeur,
dans lequel lesdits moyens de fixation sont configurés pour fixer le boitier de manière amovible, sur la cuve agitatrice du camion malaxeur.Thus, according to one aspect, there is proposed a device for monitoring the delivery of the load of a mixer truck comprising an agitating tank, the monitoring device comprising a box with:
  • at least one gyroscope and / or at least one accelerometer mounted in the box and providing data, and
  • means for fixing the unit to the mixer truck,
wherein said fixing means are configured to fix the housing in a removable manner, on the agitating tank of the mixer truck.

Ainsi, grâce au boitier amovible, il devient possible d'avoir un dispositif de suivi qui ne soit pas lié au camion malaxeur. Le boitier selon la présente invention, et donc le dispositif de suivi, peut alors n'être utilisé que lors des phases de livraison du béton, par fixation du boitier sur la cuve agitatrice avant ou après le chargement du béton par exemple, et être stocké dans les locaux de l'utilisateur du dispositif de suivi lorsqu'il n'y a plus de livraison à suivre. Ainsi, lors du nettoyage de la cuve agitatrice, le boitier peut en être retiré afin d'éviter tout risque de casse ou de panne.Thus, thanks to the removable box, it becomes possible to have a monitoring device which is not linked to the mixer truck. The box according to the present invention, and therefore the monitoring device, can then only be used during the concrete delivery phases, by fixing the box on the agitating tank before or after loading the concrete for example, and be stored at the premises of the tracking device user when there is no further delivery to track. Thus, when cleaning the agitator tank, the housing can be removed in order to avoid any risk of breakage or breakdown.

De plus, le boitier selon la présente invention peut être positionné sur n'importe quel camion malaxeur utilisé par l'utilisateur du dispositif de suivi. Les changements effectués sur une flotte de camions malaxeurs, par ajout, remplacement ou par retrait de certains camions de la flotte, ne modifient alors pas la gestion du dispositif de suivi puisque les boitiers sont indépendants des camions malaxeurs. Il suffit aux conducteurs des camions malaxeurs d'aller récupérer un boitier dans les locaux de l'utilisateur du dispositif de suivi, puis de le fixer sur la cuve agitatrice du camion malaxeur pour rendre opérationnel le suivi, puis de le retirer du camion malaxeur lorsque le camion malaxeur n'est plus utilisé.In addition, the box according to the present invention can be positioned on any mixer truck used by the user of the tracking device. The changes made to a fleet of mixer trucks, by adding, replacing or removing certain trucks from the fleet, then do not modify the management of the monitoring device since the units are independent of the concrete mixer trucks. The drivers of the mixer trucks simply have to go and retrieve a box from the premises of the user of the monitoring device, then attach it to the agitating tank of the mixer truck to make the monitoring operational, then remove it from the mixer truck when the mixer truck is no longer used.

En effet, le boitier est indépendant du camion malaxeur. Il peut ainsi être librement fixé ou retiré de la cuve de n'importe quel camion malaxeur. Le boitier est également autonome. En particulier, le boitier n'utilise pas de ressource du camion, par exemple énergétique, et n'utilise également pas de données fournies par des capteurs ou des parties du camion malaxeur : le boitier est configuré pour récupérer les informations indépendemment du camion malaxeur sur lequel il est fixé.Indeed, the box is independent of the mixer truck. It can thus be freely attached or removed from the tank of any mixer truck. The box is also autonomous. In particular, the unit does not use any resource from the truck, for example energy, and also does not use data supplied by sensors or parts of the mixer truck: the unit is configured to retrieve the information independently of the mixer truck on which it is fixed.

Préférentiellement, le boitier comprend une centrale inertielle comportant au moins trois gyroscopes et au moins trois accéléromètres.Preferably, the box comprises an inertial unit comprising at least three gyroscopes and at least three accelerometers.

La centrale inertielle permet de connaître les mouvements qu'effectue le boitier. Il devient alors possible d'enregistrer ou bien de communiquer à une personne, les différents mouvements du boitier, et donc de la cuve agitatrice du camion malaxeur. En particulier, différents événements, prévus ou non, peuvent ainsi être détectés ou communiqués par le boitier, par exemple un arrêt prolongé du camion malaxeur ou bien encore un changement de sens de rotation de la cuve agitatrice.The inertial unit makes it possible to know the movements made by the box. It then becomes possible to record or to communicate to a person, the various movements of the box, and therefore of the agitating tank of the mixer truck. In particular, various events, planned or not, can thus be detected or communicated by the unit, for example a prolonged stoppage of the mixer truck or even a change in the direction of rotation of the agitator tank.

Préférentiellement, les moyens de fixation comprennent des aimants configurés pour fixer le boitier sur la cuve agitatrice du camion malaxeur.Preferably, the fixing means comprise magnets configured to fix the box on the agitating tank of the mixer truck.

Les aimants permettent une fixation réversible du boitier sur la cuve agitatrice, et sont aisés à utiliser. En particulier, les aimants ne nécessitent pas de support sur la cuve mais peuvent venir s'y fixer directement, sans élément intermédiaire. Par ailleurs, les aimants limitent également les risques de mauvaise fixation susceptible de conduire à une chute, et donc une perte, du boitier.The magnets allow a reversible fixing of the box on the agitating tank, and are easy to use. In particular, the magnets do not require a support on the tank but can be fixed there directly, without an intermediate element. In addition, the magnets also limit the risks of poor fixing likely to lead to a fall, and therefore a loss, of the case.

Préférentiellement, le boitier comprend également un moyen d'activation configuré pour pouvoir indiquer lorsque le boitier est fixé à une cuve agitatrice d'un camion malaxeur.Preferably, the box also comprises an activation means configured to be able to indicate when the box is fixed to a stirring tank of a mixer truck.

Le moyen d'activation permet de savoir, lors du suivi par le dispositif de suivi, à quels moments le boitier est fixé sur une cuve agitatrice et à quels moments il en est détaché ou en est tombé. Un tel moyen d'activation permet alors de rendre plus fiable le traitement des autres informations communiquées par le boitier. Alternativement, un tel moyen d'activation permet de laisser en veille les capteurs et l'électronique du boitier lorsque celui-ci n'est pas fixé sur une cuve agitatrice, et donc d'en économiser la batterie, et de n'enregistrer ou communiquer les informations des capteurs uniquement lorsque le boitier est fixé sur la cuve agitatrice. Le fonctionnement du boitier par le conducteur du camion malaxeur devient ainsi particulièrement aisé et intuitif puisqu'il suffit juste d'actionner le moyen d'activation du boitier au moment où la livraison commence et où on souhaite avoir un suivi de celle-ci, pour que le boitier devienne effectivement opérationnel.The activation means make it possible to know, during monitoring by the monitoring device, at what times the box is fixed on a stirring tank and at what times it is detached from it or has fallen from it. Such an activation means then makes it possible to make the processing of the other information communicated by the box more reliable. Alternatively, such an activation means makes it possible to leave the sensors and the electronics of the box on standby when the latter is not attached to a stirring tank, and therefore to save the battery, and not to record or communicate sensor information only when the unit is attached to the agitator tank. The operation of the box by the driver of the mixer truck thus becomes particularly easy and intuitive since it is enough just to actuate the activation means of the box at the moment when the delivery begins and when one wishes to have a follow-up thereof, to that the box actually becomes operational.

Préférentiellement, le moyen d'activation est configuré pour automatiquement détecter lorsque le boitier est fixé à une cuve agitatrice.Preferably, the activation means is configured to automatically detect when the box is fixed to a stirring tank.

Dans un tel mode de réalisation, l'activation du boitier n'est pas effectuée par une personne, par exemple par le conducteur du camion malaxeur, mais s'effectue automatiquement lorsque le boitier est fixé sur une cuve agitatrice. L'utilisation du boitier s'en trouve encore plus simplifiée puisque le conducteur du camion malaxeur n'a plus qu'à le fixer sur la cuve agitatrice.In such an embodiment, the activation of the box is not carried out by a person, for example by the driver of the mixer truck, but is carried out automatically when the box is fixed on a stirring tank. The use of the box is even more simplified since the driver of the mixer truck only has to fix it on the agitator tank.

Préférentiellement, le moyen d'activation comporte un bouton faisant saillie en-dehors du boitier sur une longueur supérieure à la distance séparant le boitier d'une cuve agitatrice lorsque le boitier est fixé sur une cuve agitatrice, de manière à ce que la fixation du boitier sur une cuve agitatrice provoque l'appui sur le bouton.Preferably, the activation means comprises a button projecting outside the box over a length greater than the distance separating the box from a stirring tank when the box is fixed on a stirring tank, so that the fixing of the box on a stirring tank causes the button to be pressed.

Dans un tel mode de réalisation, l'activation du boitier s'effectue par appui sur un bouton destiné à se retrouver entre le corps du boitier et la cuve agitatrice. La forme du boitier, notamment du corps et du bouton, est configurée pour que le bouton se retrouve enfoncé par la paroi de la cuve agitatrice lorsque le boitier est fixé sur ladite cuve agitatrice. A l'inverse, lorsque le boitier est détaché de la cuve agitatrice, cela libère le bouton et donc désactive le fonctionnement du boitier, par exemple pour en économiser les batteries.In such an embodiment, the box is activated by pressing a button intended to be located between the body of the box and the agitating tank. The shape of the housing, in particular of the body and of the button, is configured so that the button is found depressed by the wall of the agitating tank when the housing is fixed to said agitating tank. Conversely, when the box is detached from the agitating tank, this releases the button and therefore deactivates the operation of the box, for example to save the batteries.

Préférentiellement, le boitier comprend également des moyens de communication, de préférence sans fil et plus préférentiellement des moyens de communication GSM, recevant en entrées les données fournies par le ou les gyroscopes et/ou le ou les accéléromètres.Preferably, the box also comprises communication means, preferably wireless and more preferably GSM communication means, receiving as inputs the data supplied by the gyroscope (s) and / or the accelerometer (s).

Les moyens de communication permettent de transmettre les données fournies par les capteurs du boitier à une personne distante. Il devient alors possible de superviser, en direct et à distance, la livraison de béton d'un camion malaxeur et, plus généralement, les livraisons de béton par plusieurs camions malaxeurs. Il devient notamment possible de détecter si le site de déchargement est libre ou au contraire déjà bloqué par plusieurs camions malaxeurs en attente de décharger le béton contenu dans leur cuve agitatrice, et donc d'adapter en conséquence le déplacement d'autres camions malaxeurs vers le site de déchargement.The means of communication make it possible to transmit the data supplied by the sensors of the box to a distant person. It then becomes possible to supervise, directly and remotely, the delivery of concrete from a mixer truck and, more generally, the deliveries of concrete by several mixer trucks. In particular, it becomes possible to detect whether the unloading site is free or, on the contrary, already blocked by several mixer trucks waiting to unload the concrete contained in their agitator tank, and therefore to adapt the movement of other mixer trucks towards the site accordingly. unloading site.

Préférentiellement, le boitier comprend également un moyen de géolocalisation et/ou un capteur de température et/ou une alimentation électrique.Preferably, the box also comprises a geolocation means and / or a temperature sensor and / or an electrical supply.

Le moyen de géolocalisation permet de connaître, en plus des données fournies par les capteurs du boitier, la position du camion malaxeur lors de l'obtention desdites données. On peut ainsi améliorer le suivi de livraison en comprenant mieux les éventuelles anomalies détectées par le boitier, par exemple une panne du camion malaxeur ou un arrêt prolongé imposé par la circulation, et en agissant en conséquence.The geolocation means makes it possible to know, in addition to the data supplied by the sensors of the box, the position of the mixer truck when said data is obtained. It is thus possible to improve delivery monitoring by better understanding any anomalies detected by the unit, for example a breakdown of the mixer truck or a prolonged stop imposed by traffic, and by acting accordingly.

Préférentiellement, les moyens de fixation sont configurés pour s'adapter à la courbure de la surface de la cuve agitatrice, quelle que soit l'orientation du boitier sur la cuve agitatrice. De préférence, les moyens de fixation sont montés mobiles sur le boitier, par exemple coulissant selon une direction perpendiculaire à la surface de la cuve agitatrice.Preferably, the fixing means are configured to adapt to the curvature of the surface of the agitating tank, regardless of the orientation of the housing on the agitating tank. Preferably, the fixing means are movably mounted on the housing, for example sliding in a direction perpendicular to the surface of the agitating tank.

Les cuves agitatrices des camions malaxeurs sont généralement de forme cylindrique, avec une paroi avant arrondie et une paroi latérale présentant plusieurs inclinaisons différentes par rapport à l'axe du cylindre. Les moyens de fixation sont ainsi configurés pour s'adapter à la paroi de la cuve agitatrice sur laquelle ils sont amenés à se fixer, de manière à permettre une fixation efficace et à limiter les contraintes mécaniques sur le boitier. Les moyens de fixation peuvent ainsi être montés coulissant par rapport au boitier, ou plus précisément au corps de boitier, afin de permettre un contact entre les moyens de fixation et la paroi de la cuve agitatrice sans forcer le boitier à se déformer en raison de la courbure de la cuve agitatrice.The agitator tanks of mixer trucks are generally cylindrical in shape, with a rounded front wall and a side wall having several different inclinations with respect to the axis of the cylinder. The fixing means are thus configured to adapt to the wall of the agitating tank on which they are made to be fixed, so as to allow effective fixing. and to limit the mechanical stresses on the case. The fixing means can thus be mounted to slide with respect to the case, or more precisely to the case body, in order to allow contact between the fixing means and the wall of the agitating tank without forcing the case to deform due to the curvature of the agitator tank.

Préférentiellement, le dispositif de suivi, et de préférence le boitier, comprend également un moyen de traitement des données fournies par le ou les gyroscopes et/ou le ou les accéléromètres, et configuré pour identifier une ou plusieurs étapes de livraison du chargement du camion malaxeur, telles que le chargement, l'arrivée sur site, et/ou le déchargement du béton par le camion malaxeur, à partir des données fournies par le ou les gyroscopes et/ou le ou les accéléromètres, par exemple à partir du sens de rotation de la cuve agitatrice et/ou à partir du déplacement ou de l'arrêt du camion malaxeur.Preferably, the monitoring device, and preferably the box, also comprises a means of processing the data supplied by the gyroscope (s) and / or the accelerometer (s), and configured to identify one or more stages of delivery of the loading of the mixer truck. , such as loading, arrival on site, and / or unloading of concrete by the mixer truck, from the data provided by the gyroscope (s) and / or the accelerometer (s), for example from the direction of rotation from the agitator tank and / or from moving or stopping the mixer truck.

Le moyen de traitement des données peut être monté dans le boitier. Dans ce cas, le moyen de traitement des données permet de récupérer et d'analyser directement in situ les données fournies par le ou les capteurs du boitier. Ainsi, au lieu de transmettre l'ensemble des données fournies par les capteurs, le boitier peut ne transmettre que les données traitées ou les données pertinentes, par exemple l'état d'avancement des étapes principales d'une livraison, notamment afin de limiter la consommation des batteries du boitier.The data processing means can be mounted in the box. In this case, the data processing means makes it possible to recover and analyze directly in situ the data supplied by the sensor (s) of the box. Thus, instead of transmitting all the data provided by the sensors, the box can only transmit the processed data or the relevant data, for example the progress of the main stages of a delivery, in particular in order to limit the consumption of the batteries of the box.

Alternativement, le moyen de traitement de données peut être distant du boitier, par exemple peut être situé dans un serveur pouvant communiquer avec le boitier. Dans ce cas, les différentes données obtenues par les capteurs du boitier sont transmises à un moyen de supervision comprenant le moyen de traitement des données distant, et l'analyse de ces données n'est pas effectuée in situ, par le boitier lui-même, mais par le moyen de supervision distant, selon par exemple les informations souhaitées par l'utilisateur à un instant donné. Dans ce cas, le boitier est amené à transmettre plus d'informations, mais ne consomme pas d'énergie pour le traitement des données.Alternatively, the data processing means can be remote from the box, for example can be located in a server that can communicate with the box. In this case, the various data obtained by the sensors of the box are transmitted to a supervision means comprising the remote data processing means, and the analysis of these data is not carried out in situ, by the box itself. , but by the remote supervision means, depending for example on the information desired by the user at a given time. In this case, the box is required to transmit more information, but does not consume energy for data processing.

Description des modes de réalisationDescription of the embodiments

La figure 1 représente un camion malaxeur 1 pour la livraison de béton notamment. Le camion malaxeur 1 comprend ainsi une cuve agitatrice 2 montée en rotation autour de son axe O. La cuve agitatrice 2 présente une forme générale cylindrique, avec un côté avant 4, ou tête, une face latérale 6 et un côté arrière 8.The figure 1 represents a mixer truck 1 for the delivery of concrete in particular. The mixer truck 1 thus comprises an agitator tank 2 mounted in rotation around its axis O. The agitator tank 2 has a generally cylindrical shape, with a front side 4, or head, a lateral face 6 and a rear side 8.

Sur la figure 1, la face latérale 6 de la cuve agitatrice 2 comporte trois sections 6a, 6b et 6c adjacentes. La première portion 6a, située du côté de l'avant de la cuve agitatrice 2, présente une forme de tronc de cône orienté vers l'avant. La portion 6c, située du côté de l'arrière de la cuve agitatrice 2, présente une forme de tronc de cône orienté vers l'arrière. La portion 6b située entre les portions 6a et 6c, présente une forme cylindrique.On the figure 1 , the side face 6 of the agitator tank 2 comprises three adjacent sections 6a, 6b and 6c. The first portion 6a, located on the side of the front of the agitating tank 2, has the shape of a truncated cone oriented towards the front. The portion 6c, located on the rear side of the stirring tank 2, has the shape of a truncated cone oriented towards the rear. The portion 6b located between the portions 6a and 6c has a cylindrical shape.

Le côté avant 4 de la cuve agitatrice 2 est fermé par une paroi arrondie, et est monté sur un moyen d'entraînement 10 configuré pour entraîner en rotation la cuve agitatrice 2. L'entraînement en rotation de la cuve agitatrice 2 a pour but d'éviter la prise du béton contenu dans celle-ci lors de l'acheminement du béton jusqu'au site de déchargement. Par ailleurs, le moyen d'entraînement 10 permet également, lorsque le sens de rotation est inversé, de décharger le béton contenu dans la cuve agitatrice 2.The front side 4 of the agitating vessel 2 is closed by a rounded wall, and is mounted on a drive means 10 configured to rotate the agitating vessel 2. The rotational drive of the agitating vessel 2 is for the purpose of '' avoid setting the concrete contained therein when conveying the concrete to the unloading site. Furthermore, the drive means 10 also makes it possible, when the direction of rotation is reversed, to unload the concrete contained in the agitating tank 2.

Le côté arrière 8 est ouvert et permet le chargement du béton dans la cuve agitatrice 2, par exemple depuis un moyen d'accueil 12 en forme d'entonnoir, et le déchargement du béton contenu dans la cuve agitatrice 2, par exemple depuis un moyen de distribution 14 monté en rotation par rapport au camion malaxeur 1.The rear side 8 is open and allows the loading of the concrete into the agitating tank 2, for example from a reception means 12 in the form of a funnel, and the unloading of the concrete contained in the agitating tank 2, for example from a means distribution valve 14 mounted in rotation with respect to the mixer truck 1.

Afin de permettre le suivi de la livraison de béton depuis le site de chargement jusqu'au site de déchargement, ainsi qu'éventuellement le retour du camion malaxeur au site de chargement, l'invention propose un dispositif de suivi 16 destiné à permettre un suivi à distance de la livraison du béton et représenté schématiquement à la figure 2.In order to allow the monitoring of the delivery of concrete from the loading site to the unloading site, as well as possibly the return of the mixer truck to the loading site, the invention provides a monitoring device 16 intended to allow remote monitoring of the delivery of concrete and shown schematically on figure 2 .

Le dispositif de suivi 16 comprend ainsi un boitier 18 destiné à se fixer sur la cuve agitatrice 2 du camion malaxeur 1, et plus particulièrement sur le côté avant 4 ou la paroi latérale 6 de la cuve agitatrice 2. Le boitier 18 est illustré de manière schématique sur la figure 2, avec les moyens fonctionnels qu'il comprend, et est représenté en perspective sur la figure 3. Le boitier 18 peut notamment comprendre un contenant 19, ou boite, dans lequel sont montés les différents moyens du boitier 18, ainsi qu'une alimentation électrique (non représentée), par exemple une batterie rechargeable, ou accumulateurs, ou bien des piles.The monitoring device 16 thus comprises a box 18 intended to be fixed on the agitating tank 2 of the mixer truck 1, and more particularly on the front side 4 or the side wall 6 of the agitating tank 2. The box 18 is illustrated in such a manner. schematic on the figure 2 , with the functional means that it includes, and is represented in perspective on the figure 3 . The box 18 may in particular comprise a container 19, or box, in which the various means of the box 18 are mounted, as well as an electric power supply (not shown), for example a rechargeable battery, or accumulators, or else batteries.

Le boitier 18 a pour but de collecter des informations sur le fonctionnement du camion malaxeur 1 et de la cuve agitatrice 2. Le boitier 18 comprend ainsi au moins un accéléromètre 20 et/ou au moins un gyroscope 22 permettant de détecter au moins un déplacement du camion malaxeur 1 et/ou une rotation de la cuve agitatrice 2, et fournissant des données correspondantes. Le but des capteurs est notamment de pouvoir détecter le déplacement du camion malaxeur 1, afin de savoir si celui-ci est en cours d'acheminement, est bloqué sur la route ou bien est sur un site de chargement ou de déchargement, tandis que le gyroscope permet de savoir si, et dans quel sens, la cuve agitatrice 2 tourne et donc de savoir notamment si le béton est toujours en cours d'acheminement ou bien si le béton est train ou a été déchargé sur le site de déchargement.The purpose of the box 18 is to collect information on the operation of the mixer truck 1 and of the agitating tank 2. The box 18 thus comprises at least one accelerometer 20 and / or at least one gyroscope 22 making it possible to detect at least one movement of the mixer truck 1 and / or a rotation of the agitator tank 2, and providing corresponding data. The purpose of the sensors is in particular to be able to detect the movement of the mixer truck 1, in order to know whether the latter is in transit, is blocked on the road or is on a loading or unloading site, while the gyroscope makes it possible to know if, and in what direction, the agitating tank 2 turns and therefore to know in particular if the concrete is still being conveyed or if the concrete is underway or has been unloaded on the unloading site.

Le boitier 18 peut comprendre de préférence une centrale inertielle comportant au moins trois accéléromètres montés selon les trois directions de l'espace, et au moins trois gyroscopes montés selon les trois directions de l'espace. Une centrale inertielle permet donc de détecter tous les déplacements et rotations du boitier 18 dans l'espace : une centrale inertielle permet ainsi de déterminer les déplacements et rotations du boitier, quelle que soit la position dans laquelle le boitier 18 est fixé sur la cuve agitatrice 2 du camion malaxeur 1. Avec une centrale inertielle, il n'est alors plus nécessaire de prévoir un montage du boitier 18 sur la cuve agitatrice 2 selon une direction spécifique, notamment pour s'assurer que les mesures effectuées par les capteurs seront exploitables.The box 18 can preferably comprise an inertial unit comprising at least three accelerometers mounted in the three directions of space, and at least three gyroscopes mounted in the three directions of space. An inertial unit therefore makes it possible to detect all the movements and rotations of the unit 18 in space: an inertial unit thus makes it possible to determine the movements and rotations of the unit, regardless of the position in which the unit 18 is fixed on the agitating tank. 2 of the mixer truck 1. With an inertial unit, it is then no longer necessary to provide for mounting the box 18 on the agitating tank 2 in a specific direction, in particular to ensure that the measurements made by the sensors will be usable.

Le boitier 18 peut également comprendre d'autres capteurs, afin de fournir une information plus riche sur les conditions d'acheminement du béton par le camion malaxeur 1. Le boitier 18 peut ainsi comprendre un moyen de géolocalisation 24, permettant de connaître la position du camion malaxeur 1 et donc de confirmer les informations fournies par ailleurs par le ou les accéléromètres. Le moyen de géolocalisation 24 peut permettre de localiser la position du camion malaxeur 1 lorsque celui-ci se trouve bloqué lors de l'acheminement du béton, par exemple à cause du trafic automobile ou bien à cause d'une panne. Il peut également permettre de savoir si le camion malaxeur 1 est déjà sur le site de déchargement mais en attente de pouvoir décharger son béton, notamment parce qu'il y a déjà plusieurs autres camions malaxeurs devant lui.The box 18 can also include other sensors, in order to provide richer information on the conveying conditions of the concrete by the mixer truck 1. The box 18 can thus include a geolocation means 24, making it possible to know the position of the concrete. mixer truck 1 and therefore to confirm the information provided elsewhere by the accelerometer (s). The geolocation means 24 can make it possible to locate the position of the mixer truck 1 when the latter is blocked during the delivery of concrete, for example because of automobile traffic or else because of a breakdown. It can also make it possible to know whether the mixer truck 1 is already on the unloading site but waiting to be able to unload its concrete, in particular because there are already several other mixer trucks in front of it.

De même, le boitier 18 peut comprendre un capteur de température 26 permettant de mesurer et de fournir la température à proximité immédiate de la cuve agitatrice 2. Un tel capteur de température 26 permet notamment de connaître les conditions d'acheminement du béton, et de s'assurer que les conditions météorologiques, en particulier la température, sont compatibles avec l'utilisation du béton contenu dans la cuve agitatrice.Likewise, the box 18 can include a temperature sensor 26 making it possible to measure and supply the temperature in the immediate vicinity of the agitating tank 2. Such a temperature sensor 26 makes it possible in particular to know the conditions for conveying the concrete, and to ensure that the weather conditions, in particular the temperature, are compatible with the use of the concrete contained in the agitator tank.

Le boitier 18 comprend également des moyens de communication 28 configurés pour transmettre les données qu'il reçoit à des moyens de communication 30, par exemple à un serveur. Les moyens de communication 28 peuvent être notamment des moyens de transmission des données de manière dématérialisée. Il peut s'agir dans ce cas d'une transmission sans fil, via les réseaux de téléphonie mobile par exemple, et plus précisément via le protocole LTE-M notamment qui utilise le réseau 4G de téléphonie mobile, ou via d'autres protocoles de communication sans fil tels que les transmissions WIFI ou BLUETOOTH. Dans ce cas, les moyens de communication 30 peuvent être distants des moyens de communication 28. Les moyens de communication 28 peuvent alors permettre une communication en temps réel des données collectées par les capteurs du boitier 18, à un serveur distant, ce qui permet de superviser à distance l'état de la livraison du béton.The box 18 also comprises communication means 28 configured to transmit the data that it receives to communication means 30, for example to a server. The means of communication 28 may in particular be means of transmitting data in a dematerialized manner. In this case, it may be a wireless transmission, via mobile telephone networks for example, and more precisely via the LTE-M protocol, in particular which uses the 4G mobile telephone network, or via other communication protocols. wireless communication such as WIFI or BLUETOOTH transmissions. In this case, the communication means 30 can be remote from the communication means 28. The communication means 28 can then allow real-time communication of the data collected by the sensors of the box 18, to a remote server, which makes it possible to remotely supervise the delivery status of the concrete.

Alternativement, les moyens de communication 28 peuvent être des moyens de transmission filaire, par exemple via un câble ou une connexion USB. Dans ce cas, les données fournies par le boitier 18 peuvent être utilisées pour s'assurer, à postériori, du bon déroulement de la livraison et/ou pour connaître et sauvegarder les conditions de livraison du béton.Alternatively, the communication means 28 can be wire transmission means, for example via a cable or a USB connection. In this In this case, the data provided by the box 18 can be used to ensure, a posteriori, that the delivery has gone smoothly and / or to know and save the concrete delivery conditions.

Dans les deux cas, les données fournies par le boitier au moyen de communication 30 sont ensuite transmises par le moyen de communication 30 à un moyen de supervision 32. Le moyen de supervision 32 peut être configuré pour uniquement afficher les données reçues du boitier 18, ou au contraire être configuré pour afficher les données et envoyer des requêtes au boitier 18 via les moyens de communication 30, 28, de manière à établir une interaction entre le moyen de supervision 32 et le boitier 18. Par exemple, le moyen de supervision 32 peut être configuré pour envoyer des requêtes au boitier 18, mais également pour paramétrer, à distance donc, les réglages du boitier 18, tels que notamment les seuils de détections, ou de sensibilité, du boitier 18.In both cases, the data supplied by the box to the communication means 30 are then transmitted by the communication means 30 to a supervision means 32. The supervision means 32 can be configured to only display the data received from the box 18, or on the contrary be configured to display the data and send requests to the box 18 via the communication means 30, 28, so as to establish an interaction between the supervision means 32 and the box 18. For example, the supervision means 32 can be configured to send requests to box 18, but also to configure, therefore remotely, the settings of box 18, such as in particular the detection or sensitivity thresholds of box 18.

Le moyen de supervision 32 peut également être configuré pour traiter les données reçues, par exemple pour traiter les données brutes fournies par les capteurs du boitier 18 et transmises par les moyens de communication 28, ou bien pour opérer un deuxième niveau de traitement sur les données éventuellement déjà traitées fournies par le boitier 18.The supervision means 32 can also be configured to process the data received, for example to process the raw data supplied by the sensors of the box 18 and transmitted by the communication means 28, or else to operate a second level of processing on the data. possibly already processed provided by the box 18.

Le moyen de supervision 32 peut enfin être configuré pour également, voire uniquement, enregistrer et sauvegarder les informations collectées par le boitier 18.The supervision means 32 can finally be configured to also, or even only, record and save the information collected by the box 18.

Dans le cas illustré sur la figure 2, le dispositif de suivi 16 ne comprend qu'un seul boitier 18. Néanmoins, on comprend que le dispositif de suivi 16 peut, voire est prévu pour, comprendre plusieurs boitiers 18 utilisés en parallèle sur plusieurs camions malaxeurs 1. Le moyen de supervision 32 est dans ce cas configuré pour permettre le suivi et la gestion des différents boitiers 18, en même temps, en exploitant les données transmises par chacun des boitiers 18. Il devient alors aisé de superviser, mais aussi d'adapter, les livraisons des différents camions malaxeurs 1 en fonction des données collectées directement par les boitiers 18 sur les camions malaxeurs 1 en déplacement.In the case illustrated on figure 2 , the monitoring device 16 only comprises a single box 18. Nevertheless, it is understood that the monitoring device 16 can, or even is intended to, comprise several boxes 18 used in parallel on several mixer trucks 1. The supervision means 32 is in this case configured to allow the monitoring and management of the different boxes 18, at the same time, by exploiting the data transmitted by each of the boxes 18. It then becomes easy to supervise, but also to adapt, the deliveries of the different trucks mixers 1 as a function of the data collected directly by the boxes 18 on the mixer trucks 1 on the move.

A titre d'exemple, le moyen de supervision 32 peut être une application disponible sur un serveur et installée sur un terminal, tel qu'un ordinateur ou un smartphone. Une telle application présente notamment l'avantage de pouvoir être mise à jour, par exemple afin d'en enrichir les fonctionnalités ou bien pour l'adapter aux différentes situations pouvant être rencontrées lors de l'utilisation du dispositif de suivi 16.By way of example, the supervision means 32 can be an application available on a server and installed on a terminal, such as a computer or a computer. smartphone. Such an application has in particular the advantage of being able to be updated, for example in order to enrich its functionalities or else to adapt it to the different situations that may be encountered when using the monitoring device 16.

Dans l'exemple illustré à la figure 2, les données fournies par les capteurs 20, 22, 24 et 26 ne sont pas transmises directement aux moyens de communication 28, mais sont reliés, par leur sortie, à un moyen de traitement de données 34. Le moyen de traitement de données 34 permet ainsi de récupérer les différentes données fournies par le ou les accéléromètres 20, le ou les gyroscopes 22, le moyen de géolocalisation 24 et le capteur de température 26, et de les traiter pour en déduire une information traitée exploitable et plus petite en taille. Le moyen de traitement de données 34 peut notamment être configuré pour identifier une ou plusieurs étapes de livraison du béton, telles que le chargement, l'arrivée sur site et/ou le déchargement du béton, à partir des données fournies par les différents capteurs du boitier 18. Par exemple, un changement de sens de rotation de la cuve agitatrice 2 peut être analysé par le moyen de traitement des données 34, comme un déchargement du béton contenu dans la cuve agitatrice 2 sur le site de déchargement. L'information traitée par le moyen de traitement de données 34 peut ensuite être transmise aux moyens de communication 28 pour transmission au moyen de supervision 32.In the example shown in figure 2 , the data supplied by the sensors 20, 22, 24 and 26 are not transmitted directly to the communication means 28, but are connected, by their output, to a data processing means 34. The data processing means 34 allows thus recovering the various data supplied by the accelerometer (s) 20, the gyroscope (s) 22, the geolocation means 24 and the temperature sensor 26, and processing them to deduce therefrom processed information that is usable and smaller in size. The data processing means 34 can in particular be configured to identify one or more stages of delivery of the concrete, such as the loading, the arrival on site and / or the unloading of the concrete, from the data provided by the various sensors of the box 18. For example, a change in the direction of rotation of the agitator tank 2 can be analyzed by the data processing means 34, such as an unloading of the concrete contained in the agitator tank 2 on the unloading site. The information processed by the data processing means 34 can then be transmitted to the communication means 28 for transmission to the supervision means 32.

Le moyen de traitement de données 34 peut également être configuré pour échanger avec le moyen de supervision 32, via les moyens de communication 28, 30. Ainsi, le moyen de traitement des données peut être configuré pour pouvoir traiter et répondre aux requêtes du moyen de supervision 32. Le moyen de supervision 32 peut également être configuré pour pouvoir, notamment à distance, mettre à jour le moyen de traitement de données 34, c'est-à-dire remplacer le logiciel interne (ou firmware) du moyen de traitement de données 34. Il devient ainsi possible de mettre facilement à niveau, et donc de faire évoluer, le ou les boitiers 18 sans nécessiter de les récupérer physiquement au préalable.The data processing means 34 can also be configured to communicate with the supervision means 32, via the communication means 28, 30. Thus, the data processing means can be configured to be able to process and respond to requests from the communication means. supervision 32. The supervision means 32 can also be configured to be able, in particular remotely, to update the data processing means 34, that is to say to replace the internal software (or firmware) of the data processing means. data 34. It thus becomes possible to easily upgrade, and therefore to upgrade, the box or boxes 18 without having to physically retrieve them beforehand.

Le moyen de traitement des données 34 permet ainsi de réduire la quantité d'informations transmises par les moyens de transmission 28, et donc d'en limiter la consommation électrique, même si le moyen de traitement de données 34 consomme également de l'énergie électrique.The data processing means 34 thus makes it possible to reduce the quantity of information transmitted by the transmission means 28, and therefore to limit it. power consumption, even if the data processing means 34 also consumes electric power.

Le boitier 18 peut également comprendre un moyen d'activation 36. Le moyen d'activation 36 est un moyen configuré pour détecter, de préférence automatiquement, lorsque le boitier 18 est fixé à une cuve agitatrice 2 d'un camion malaxeur 1. Le moyen d'activation 36 peut ainsi être configuré pour déclencher le fonctionnement du boitier 18 lorsque celui-ci est fixé sur la cuve agitatrice 2 d'un camion malaxeur 1. Le moyen d'activation 36 peut notamment déclencher les mesures par les différents capteurs du boitier 18, et éventuellement le traitement des données par le moyen de traitement 34 ou encore l'émission/réception de données par les moyens de communication 28.The box 18 may also include an activation means 36. The activation means 36 is a means configured to detect, preferably automatically, when the box 18 is fixed to a stirrer tank 2 of a mixer truck 1. The means activation 36 can thus be configured to trigger the operation of the box 18 when the latter is fixed to the agitating tank 2 of a mixer truck 1. The activation means 36 can in particular trigger the measurements by the various sensors of the box 18, and possibly the processing of the data by the processing means 34 or the transmission / reception of data by the communication means 28.

Le moyen d'activation 36 a pour but notamment d'activer les fonctionnalités du boitier 18, de préférence automatiquement, lorsque celui-ci vient à être positionné sur la cuve agitatrice 2 d'un camion malaxeur 1.The purpose of the activation means 36 is in particular to activate the functionalities of the box 18, preferably automatically, when the latter is positioned on the agitating tank 2 of a mixer truck 1.

Alternativement, ou en complément, le moyen d'activation 36 peut également être configuré pour pouvoir indiquer lorsque le boitier est fixé sur la cuve agitatrice 2 d'un camion malaxeur.Alternatively, or in addition, the activation means 36 can also be configured to be able to indicate when the box is fixed on the agitating tank 2 of a mixer truck.

A cet effet, le moyen d'activation 36 peut comprendre un bouton 38 monté sur le boitier 18, et plus particulièrement sur le contenant 19, du côté destiné à venir se fixer sur une surface de la cuve. Le bouton 38 fait saillie en-dehors du boitier 18, et plus particulièrement en-dehors du contenant 19, et sur une longueur supérieure à la distance séparant le boitier 18 de la cuve agitatrice 2, lorsque le boitier est fixé sur une cuve agitatrice 2. Ainsi, lorsque le boitier 18 est fixé sur une cuve agitatrice 2, le bouton 38 est automatiquement enfoncé par la paroi de la cuve sur laquelle est fixé le boitier 18 : cela permet de détecter automatiquement, sans nécessiter aucune action spécifique de la part de la personne venant placer le boitier sur la cuve, que le boitier 18 est monté sur une cuve et que les différents capteurs du boitier 18 peuvent être rendus actifs.To this end, the activation means 36 may comprise a button 38 mounted on the box 18, and more particularly on the container 19, on the side intended to be fixed on a surface of the tank. The button 38 protrudes outside the box 18, and more particularly outside the container 19, and over a length greater than the distance separating the box 18 from the stirring tank 2, when the box is fixed on a stirring tank 2 Thus, when the box 18 is fixed on a stirring tank 2, the button 38 is automatically pressed by the wall of the tank on which the box 18 is fixed: this makes it possible to detect automatically, without requiring any specific action on the part of the operator. the person coming to place the box on the tank, that the box 18 is mounted on a tank and that the various sensors of the box 18 can be made active.

Le type du bouton 38, et plus généralement du moyen d'activation 36, peut être directement lié au mode de fixation du boitier 18 sur la cuve agitatrice 2. Les moyens de fixation du boitier 18 sont notamment configurés pour approcher le boitier 18 de la cuve agitatrice 2 d'une distance inférieure à la taille du bouton 38.The type of the button 38, and more generally of the activation means 36, can be directly linked to the method of fixing the housing 18 on the agitating tank 2. The fixing means of the housing 18 are in particular configured to bring the housing 18 closer to the agitator tank 2 from a distance less than the size of the button 38.

Selon la présente invention, le boitier 18 comprend des moyens de fixation amovibles, c'est-à-dire des moyens de fixation configurés pour fixer le boitier 18, et plus précisément le contenant 19, sur la cuve agitatrice 2 d'un camion malaxeur 1, de manière réversible. Par exemple, et comme illustré sur la figure 3, le boitier 18 comprend des moyens de fixation 40 comportant des aimants, par exemple quatre montés aux quatre coins du contenant 19 qui présente, dans le cas illustré sur la figure 3, une forme globalement parallélépipédique. Le contenant 19 peut notamment être en deux parties avec une coque et un support vissés ensemble, le support étant destiné à venir se fixer, via les moyens de fixation 40, sur la cuve agitatrice 2.According to the present invention, the box 18 comprises removable fixing means, that is to say fixing means configured to fix the box 18, and more precisely the container 19, on the agitating tank 2 of a mixer truck. 1, reversibly. For example, and as shown in the figure 3 , the box 18 comprises fixing means 40 comprising magnets, for example four mounted at the four corners of the container 19 which has, in the case illustrated in the figure 3 , a generally parallelepipedal shape. The container 19 can in particular be in two parts with a shell and a support screwed together, the support being intended to be fixed, via the fixing means 40, on the agitating tank 2.

Les moyens de fixation 40 sont configurés pour empêcher le boitier 18 de tomber de la cuve agitatrice 2, en utilisation. Ainsi, et afin de limiter les contraintes entre la cuve agitatrice 2 et le boitier 18 lorsque celui-ci est monté sur la cuve agitatrice 2, les moyens de fixation 40 sont configurés pour s'adapter à la forme de la cuve agitatrice 2, et notamment à la courbure de la paroi de la cuve agitatrice 2. Par exemple, les moyens de fixation 40 peuvent comprendre un ou plusieurs aimants montés mobiles sur le support du contenant 19. Chaque aimant peut notamment être monté sur le support par une liaison glissière, par exemple à l'extrémité d'une tige traversant le support et reliée au support par un ressort. Dans ce cas, le ressort permet de plaquer le boitier 18 sur la paroi de la cuve agitatrice 2, afin de s'assurer de l'activation du bouton 38, tout en permettant un jeu entre le boitier 18 et la cuve agitatrice 2 pour compenser l'encombrement géométrique pouvant apparaître entre le boitier 18 et la cuve agitatrice 2.The fastening means 40 are configured to prevent the housing 18 from falling from the agitator tank 2, in use. Thus, and in order to limit the stresses between the stirring tank 2 and the housing 18 when the latter is mounted on the stirring tank 2, the fixing means 40 are configured to adapt to the shape of the stirring tank 2, and in particular to the curvature of the wall of the agitating tank 2. For example, the fixing means 40 can comprise one or more magnets movably mounted on the support of the container 19. Each magnet can in particular be mounted on the support by a sliding connection, for example at the end of a rod passing through the support and connected to the support by a spring. In this case, the spring allows the housing 18 to be pressed against the wall of the agitating tank 2, in order to ensure the activation of the button 38, while allowing a clearance between the housing 18 and the agitating tank 2 to compensate. the geometric bulk that may appear between the housing 18 and the agitating tank 2.

Ainsi, grâce au boitier selon la présente invention, il devient possible d'avoir un suivi d'un ou plusieurs camions malaxeurs devant livrer du béton. Le boitier selon la présente invention peut être facilement installé et enlevé de la cuve, pour effectuer le suivi uniquement mais facilement sur les camions malaxeurs souhaités. Par ailleurs, grâce à son côté amovible et à ses fonctionnalités qui peuvent être délocalisées, il devient également plus aisé de renouveler, remplacer mais aussi améliorer les fonctionnalités de suivi du dispositif de suivi, notamment pour l'adapter aux évolutions de la flotte de camions malaxeurs, et aux contraintes de livraison.Thus, thanks to the box according to the present invention, it becomes possible to have a follow-up of one or more mixer trucks having to deliver concrete. The box according to the present invention can be easily installed and removed from the tank, for monitoring only but easily on the desired mixer trucks. In addition, thanks to its removable side and its functions that can be relocated, it also becomes easier to renew, replace but also improve the monitoring functions of the monitoring device, in particular to adapt it to changes in the truck fleet. mixers, and delivery constraints.
