Definitions

  • the present invention relates to a control system for loading and unloading or movement of goods. It applies, in particular, to all companies, public or private organizations using the transport of goods in handling or packaging units or any other container that can be handled in the same way as a container support such as a pallet ( handling by pallet truck).
  • container support or "pallet” used in this document covers any type of goods whether or not contained in containers that can be handled by a fork-lift machine (manual or electric pallet truck, forklift, stacker, etc. ..), it can be wooden pallets, plastic pallets, metal pallets, pallet boxes (wood, plastic, cardboard, wire mesh) ...
  • One of the aims of the invention is to automatically trace the movements of goods during the loading and unloading phase.
  • a prior art consists in using a laser beam bar code reader.
  • the disadvantages of this technique are that the reading area must be less than 1 meter in height, bar code reading is unreliable (of the order of 30% of unread bar code) and there is no no proof of loading or unloading
  • Another technique consists in using a portable terminal with barcode reader type PDA (for Personal Digital Assistant, in English terminology or personal digital assistant in French, also called an organizer).
  • PDA Personal Digital Assistant
  • the disadvantages of this technique are that it is not guaranteed that the identification of the container support is done before loading (the container support can be loaded and not identified), it is necessary to pause to identify the carrier of goods, and also there is no proof of loading or unloading.
  • the invention can be extended from the automatic traceability of the movements of goods during the loading and unloading phase, to the movements of goods during their movements from one warehouse to another, and to the movements of stocks in general.
  • the present invention aims to remedy these drawbacks with a completely innovative approach.
  • the present invention relates to a system for controlling the loading and unloading or movement of goods comprising a terminal positioned near the point of passage of the goods, said goods being in containers, each container having a bar code or a container support comprises a bar code, said system being remarkable in that the terminal comprises:
  • a camera-type taking device configured for taking a photo or film when at least one container passes in front of said terminal, said terminal extracts and decodes the bar code identifying the container (s) ( s) before sending said photo or said film to a database;
  • control unit comprising a microcontroller controlling the system and said database, a photo or film processing unit to identify the bar code taken in a photo or film, a unit for triggering the taking of a photo or film in function of at least:
  • the first detection cell comprising a first diffusion sensor and a second diffusion sensor indicating a passage in front of the terminal
  • the second detection cell having a first reflection sensor and a second reflection sensor, cooperating with a reflector positioned on the container (s) or the or the container support (s) or a container support handling device indicating the presence of at least one container at the terminal.
  • Diffusion sensors are installed in a single terminal, the transmitter and the receiver both being in the same housing. Diffusion sensors use the reflection of the target object within the predetermined detection range. The emitter sends out a continuous beam of light. Once it hits the target, it is scattered all over the place. Some of this light comes back and is recognized by the receiver which then sends an electrical signal to the output. Alternatively, background suppression diffusion sensors are used which utilize an adjustable sensing distance. In this case, objects with a reflective background are ignored to ensure that only objects included in the detection distance are detected. The information is then processed by the control unit.
  • the system makes it possible to automatically trace the movements of goods or containers of goods or the like:
  • the system is reliable in identifying everything on a container support passing nearby.
  • proximity is meant a distance of less than 20m.
  • Automatic identification consists of performing the following operations: [0016] - Automatically read the identification bar code of the container or of the container support without stopping the machine handling the container support (pallet truck, handling trolley, etc.), there is a continuous reading.
  • the system makes it possible to identify with certainty and proof by the photo or film the movements of containers or supports of the containers carried out within the framework of precise operations (loading / unloading of a truck, transfers of stock, transfer of zone etc ).
  • the system makes it possible to detect with certainty and proof by the photo or film the movements of containers or supports of the multiple containers pushed one behind the other, or superimposed on one another.
  • the reflection sensors are installed in a terminal and the transmitter and the receiver are in the same housing. It is therefore sufficient simply to position the reflector facing the sensor. In the present case, the reflector is positioned on the handling machine. The principle is that a detection takes place when the light beam between the emitter and the receiver is received. The reflector returns the light beam to the sensor when an object is present which makes it possible to receive the beam and causes the sending of an electrical signal by the sensor to the output. The information is then processed by the control unit.
  • the system can be easily installed anywhere in a warehouse or workshop: no need for square meters to install a terminal.
  • the system of the present invention also makes it possible to identify the container (package) and container support (pallets) and their characteristics at a distance greater than 40 cm and up to several meters (which again gives the flexibility in material flows, and give agility and flexibility to material flows).

Description

Titre de l'invention : Système de contrôle de chargement et de déchargement ou de transfert de zone de marchandises Title of the invention: Control system of loading and unloading or transfer of goods area
Domaine technique de l'invention Technical field of the invention
[0001] La présente invention concerne un système de contrôle de chargement et de déchargement ou de mouvement de marchandises. Elle s’applique, en particulier, à toutes les entreprises, organismes publics ou privés utilisant le transport de marchandises dans des unités de manutention ou de conditionnement ou tout autre contenant manipulable de la même façon comme un support de contenant tel qu’une palette (manipulation par transpalette). The present invention relates to a control system for loading and unloading or movement of goods. It applies, in particular, to all companies, public or private organizations using the transport of goods in handling or packaging units or any other container that can be handled in the same way as a container support such as a pallet ( handling by pallet truck).
[0002] Le terme « support de contenant » ou « palette » utilisé dans ce document recouvre tout type de marchandises contenu ou pas dans des contenants pouvant être manipulé par un engin de manutention à fourche (transpalette manuel ou électrique, chariot élévateur, transgerbeur etc..), il peut s’agir de palettes bois, palettes plastique, palette métal, caisse palette (bois, plastique, carton, grillagée) ... The term "container support" or "pallet" used in this document covers any type of goods whether or not contained in containers that can be handled by a fork-lift machine (manual or electric pallet truck, forklift, stacker, etc. ..), it can be wooden pallets, plastic pallets, metal pallets, pallet boxes (wood, plastic, cardboard, wire mesh) ...
Technique antérieure Prior art
[0003] Un des buts de l'invention est de tracer automatiquement les mouvements de marchandises pendant la phase de chargement et déchargement. One of the aims of the invention is to automatically trace the movements of goods during the loading and unloading phase.
[0004] Une technique antérieure consiste à utiliser un lecteur de code barre à faisceau laser. Les inconvénients de cette technique sont que la zone de lecture doit être inférieure à 1 mètre de hauteur, la lecture de code barre n'est pas fiable (de l'ordre de 30 % de code barre non lus) et il n'y a pas de preuve du chargement ou déchargement [0004] A prior art consists in using a laser beam bar code reader. The disadvantages of this technique are that the reading area must be less than 1 meter in height, bar code reading is unreliable (of the order of 30% of unread bar code) and there is no no proof of loading or unloading
[0005] Une autre technique consiste à utiliser un terminal portable avec lecteur code barre type PDA (pour Personal Digital Assistant, en terminologie anglophone ou assistant numérique personnel en français, aussi appelé organiseur). Les inconvénients de cette technique est qu’on ne garantit pas que l'identification du support de contenant soit faite avant le chargement (le support de contenant peut être chargée et non identifiée), il est nécessaire de faire une pause pour identifier le support de marchandises, et aussi il n'y a pas de preuve du chargement ou déchargement. Another technique consists in using a portable terminal with barcode reader type PDA (for Personal Digital Assistant, in English terminology or personal digital assistant in French, also called an organizer). The disadvantages of this technique are that it is not guaranteed that the identification of the container support is done before loading (the container support can be loaded and not identified), it is necessary to pause to identify the carrier of goods, and also there is no proof of loading or unloading.
Présentation de l'invention Presentation of the invention
[0006] L'invention peut être étendue de la traçabilité automatique des mouvements de marchandises pendant la phase de chargement et déchargement, aux mouvements de marchandises lors de leurs déplacements d'un entrepôt à l'autre, et aux mouvements de stocks en général The invention can be extended from the automatic traceability of the movements of goods during the loading and unloading phase, to the movements of goods during their movements from one warehouse to another, and to the movements of stocks in general.
[0007] La présente invention vise à remédier à ces inconvénients avec une approche totalement novatrice. The present invention aims to remedy these drawbacks with a completely innovative approach.
[0008] A cet effet, la présente invention vise un système de contrôle de chargement et de déchargement ou de mouvement de marchandises comportant une borne positionnée à proximité du point de passage des marchandises, lesdites marchandises étant dans des contenants chaque contenant comporte un code barre ou un support de contenant comporte un code barre, ledit système étant remarquable en ce que la borne comporte :[0008] To this end, the present invention relates to a system for controlling the loading and unloading or movement of goods comprising a terminal positioned near the point of passage of the goods, said goods being in containers, each container having a bar code or a container support comprises a bar code, said system being remarkable in that the terminal comprises:
- un dispositif de prise de vues, de type caméra, configuré pour la prise de photo ou film au moment du passage d'au moins un contenant devant ladite borne, ladite borne extrait et décode le code barre d'identification du ou des contenant(s) avant d'envoyer ladite photo ou ledit film à une base de donnée ; a camera-type taking device configured for taking a photo or film when at least one container passes in front of said terminal, said terminal extracts and decodes the bar code identifying the container (s) ( s) before sending said photo or said film to a database;
- un flash relié au dispositif de prise de vues se déclenchant lors de la prise de photos ou films; - a flash connected to the camera that is triggered when taking photos or films;
- une unité de commande, comportant un microcontrôleur pilotant le système et ladite base de donnée, une unité de traitement de la photo ou film pour identifier le code barre pris en photo ou film, une unité de déclenchement de la prise de photo ou film en fonction d'au moins : a control unit, comprising a microcontroller controlling the system and said database, a photo or film processing unit to identify the bar code taken in a photo or film, a unit for triggering the taking of a photo or film in function of at least:
- une première cellule de détection d'au moins un contenant, la première cellule de détection comportant un premier capteur à diffusion et un deuxième capteur à diffusion indiquant un passage devant la borne,- a first detection cell of at least one container, the first detection cell comprising a first diffusion sensor and a second diffusion sensor indicating a passage in front of the terminal,
- une deuxième cellule de détection, la deuxième cellule de détection ayant un premier capteur à réflexion et un deuxième capteur à réflexion, coopérant avec un réflecteur positionné sur le ou les contenant(s) ou le ou les support(s) de contenant(s) ou un engin de manutention du support de contenant indiquant la présence d'au moins un contenant à la borne. a second detection cell, the second detection cell having a first reflection sensor and a second reflection sensor, cooperating with a reflector positioned on the container (s) or the or the container support (s) or a container support handling device indicating the presence of at least one container at the terminal.
[0009] Les capteurs à diffusion sont installés dans une seule borne, l'émetteur et le récepteur étant tous deux dans le même logement. Les capteurs à diffusion utilisent la réflexion de l'objet cible au sein de la plage de détection prédéterminée. L'émetteur envoie un faisceau de lumière continu. Une fois qu'il touche la cible, il est diffusé dans tous les sens. Une partie de cette lumière revient et est reconnue par le récepteur qui envoie ensuite un signal électrique à la sortie. Dans une variante, il est utilisé des capteurs à diffusion avec suppression du fond qui font appel à une distance de détection ajustable. Dans ce cas, on ignore les objets au fond réfléchissant pour garantir que seuls les objets inclus dans la distance de détection sont détectés. L'information est ensuite traitée par l'unité de commande. Diffusion sensors are installed in a single terminal, the transmitter and the receiver both being in the same housing. Diffusion sensors use the reflection of the target object within the predetermined detection range. The emitter sends out a continuous beam of light. Once it hits the target, it is scattered all over the place. Some of this light comes back and is recognized by the receiver which then sends an electrical signal to the output. Alternatively, background suppression diffusion sensors are used which utilize an adjustable sensing distance. In this case, objects with a reflective background are ignored to ensure that only objects included in the detection distance are detected. The information is then processed by the control unit.
[0010] Grâce à ces dispositions, le système permet de tracer automatiquement les mouvements de marchandises ou contenant de marchandises ou équivalents : [0010] Thanks to these provisions, the system makes it possible to automatically trace the movements of goods or containers of goods or the like:
[0011] - Identification automatique des contenants ou supports de contenant entrant dans un entrepôt ou tout site utilisant des produits conditionnés dans des contenants ou supports de contenant en particulier lors du déchargement des camions ou de transfert de zone (tampon, de stock, ...) par une marchandise. [0011] - Automatic identification of containers or container supports entering a warehouse or any site using products packaged in containers or container supports, in particular during unloading from trucks or zone transfer (buffer, stock, .. .) by a commodity.
[0012] - identification automatique des supports de contenant sortant d'un entrepôt ou de tout site utilisant des produits conditionnés sur un support de contenant en particulier lors du chargement des camions. [0012] Automatic identification of container supports leaving a warehouse or any site using products packaged on a container support, in particular when loading trucks.
[0013] - Identification automatique des supports de contenant transitant à l'intérieur d'un entrepôt ou de tout site utilisant des produits conditionnés sur un support de contenant (captation automatique de mouvement de transfert d'un stock à l'autre, ou d'une zone à l'autre sur le même site ou d'un site à l'autre). [0013] - Automatic identification of container supports transiting inside a warehouse or any site using products packaged on a container support (automatic capture of transfer movement from one stock to another, or 'one zone to another on the same site or from one site to another).
[0014] Ainsi, le système est fiable dans l'identification de tout sur un support de contenant passant à proximité. On entend par proximité, une distance inférieure à 20m. [0014] Thus, the system is reliable in identifying everything on a container support passing nearby. By proximity is meant a distance of less than 20m.
[0015] L'dentification automatique consiste à effectuer les opérations suivantes : [0016] - Lire automatiquement le code barre d'identification du contenant ou du support de contenant sans arrêt de l'engin manipulant du support de contenant (transpalette, chariot de manutention etc...), il y a une lecture en continu. Automatic identification consists of performing the following operations: [0016] - Automatically read the identification bar code of the container or of the container support without stopping the machine handling the container support (pallet truck, handling trolley, etc.), there is a continuous reading.
[0017] - Conserver une ou plusieurs photos ou films (et la date) du contenant ou du support du contenant avec le contenant lors de son passage devant le système. [0017] - Keep one or more photos or films (and the date) of the container or the support of the container with the container when it passes in front of the system.
[0018] Le système permet d'identifier avec certitude et preuve par la photo ou film les mouvements de contenants ou supports du contenants effectués dans le cadre d'opérations précises (chargement/déchargement d'un camion, transferts de stock, transfert de zone etc...). The system makes it possible to identify with certainty and proof by the photo or film the movements of containers or supports of the containers carried out within the framework of precise operations (loading / unloading of a truck, transfers of stock, transfer of zone etc ...).
[0019] Le système permet de détecter d'identifier avec certitude et preuve par la photo ou film les mouvements de contenants ou supports du contenants multiples poussés les uns derrière les autres, ou superposés les uns sur les autres. The system makes it possible to detect with certainty and proof by the photo or film the movements of containers or supports of the multiple containers pushed one behind the other, or superimposed on one another.
[0020] Les capteurs à réflexion sont installés dans une borne et l'émetteur et le récepteur se trouvent dans le même logement. Il suffit donc tout simplement de positionner le réflecteur face au capteur. Dans le cas présent, le réflecteur est positionné sur l'engin de manutention. Le principe est qu'une détection a lieu lorsque le faisceau lumineux entre l'émetteur et le récepteur est reçu. Le réflecteur renvoie le faisceau lumineux au capteur lorsqu'un objet est présent ce qui fait que permet de recevoir le faisceau et provoque l'envoi d'un signal électrique par le capteur à la sortie. L'information est ensuite traitée par l'unité de commande. The reflection sensors are installed in a terminal and the transmitter and the receiver are in the same housing. It is therefore sufficient simply to position the reflector facing the sensor. In the present case, the reflector is positioned on the handling machine. The principle is that a detection takes place when the light beam between the emitter and the receiver is received. The reflector returns the light beam to the sensor when an object is present which makes it possible to receive the beam and causes the sending of an electrical signal by the sensor to the output. The information is then processed by the control unit.
[0021] Ainsi, le système s’installe facilement n'importe où dans un entrepôt ou atelier : pas de besoins de mètres carrés pour installer une borne. Par exemple, il possible de fixer la borne sur le quai pour sa mise en place. Dans une variante, il est possible d'avoir une borne avec des roulettes pour faciliter son déplacement et de fixer les roulettes par système de blocage pour contrôler le chargement et déchargement, ou transfert d'une zone d'entreposage à l'autre. [0021] Thus, the system can be easily installed anywhere in a warehouse or workshop: no need for square meters to install a terminal. For example, it is possible to fix the bollard on the dock for its installation. In a variant, it is possible to have a terminal with casters to facilitate its movement and to fix the castors by a locking system to control loading and unloading, or transfer from one storage area to another.
[0022] En effet la plupart des systèmes de l'état de l'art mettent une infrastructure rigide avec protection humaine (dans les faits une machine dans lesquelles passent les palettes ou colis), et vont jusqu'à rendre rigide le passage des palettes ou colis. Pour notre part, avec le système de la présente invention il est possible de l'installer sur le flux de marchandise courant sans le rigidifier. Ainsi le système n'impose pas un chemin rigide à des supports de contenant et contenant sur un convoyeur, sur un tapis roulant, ou dans une machine avec protections. In fact, most of the systems of the state of the art put a rigid infrastructure with human protection (in fact a machine in which pass pallets or packages), and go so far as to make the passage of pallets or packages rigid. For our part, with the system of the present invention it is possible to install it on the current flow of goods without stiffening it. Thus the system does not impose a rigid path on the container and container supports on a conveyor, on a conveyor belt, or in a machine with protections.
[0023] Le système de la présente invention permet d'identifier aussi les contenant (colis) et support de contenant (palettes) et leurs caractéristiques à distance supérieure à 40 cm et allant jusqu'à plusieurs mètres (ce qui donne à nouveau de la souplesse dans les flux de matières, et donnent de l'agilité et de la flexibilité aux flux matières). The system of the present invention also makes it possible to identify the container (package) and container support (pallets) and their characteristics at a distance greater than 40 cm and up to several meters (which again gives the flexibility in material flows, and give agility and flexibility to material flows).
[0024] A contrario les systèmes de l'état de l'art sont des systèmes qui ont des capteurs à quelques centimètres des colis ou palette pour les détecter. On the contrary, the systems of the state of the art are systems which have sensors a few centimeters from the packages or pallets to detect them.
[0025] Le système de la présente invention permet de flasher un support de contenant qui est en mouvement. Dans un exemple de réalisation, il a été testé d'identifier des supports de contenant à 12km/h sans problème de lecture de la photo ou film qui a pu être lue parfaitement. The system of the present invention makes it possible to flash a container support which is in motion. In an exemplary embodiment, it was tested to identify container supports at 12 km / h without reading problem of the photo or film which could be read perfectly.
[0026] Comme le système de la présente invention est flexible, il n'impose pas non plus une largeur ou longueur maximale des colis chargés. A contrario les systèmes de l'état de l'art, il existe une dimension maximale dans lesquelles rentrent des colis ou palettes. As the system of the present invention is flexible, it also does not impose a maximum width or length of the loaded packages. Unlike the systems of the state of the art, there is a maximum dimension in which packages or pallets fit.
[0027] Le système de la présente invention est compatible et adaptable à chaque contexte d'installation (nature de reconnaissance de capteur, nature des éléments physique de mesure), par exemple avec l'usage ou non de RFID, avec l'usage ou non de caméras, avec l'usage ou non de lecteurs code barre, avec l'usage ou non d'appareil photo ou caméra. The system of the present invention is compatible and adaptable to each installation context (nature of sensor recognition, nature of the physical measurement elements), for example with the use or not of RFID, with the use or not of cameras, with the use or not of bar code readers, with the use or not of camera or camera.
[0028] L'invention est avantageusement mise en œuvre selon les modes de réalisation et les variantes exposées ci-après, lesquelles sont à considérer individuellement ou selon toute combinaison techniquement opérante. The invention is advantageously implemented according to the embodiments and the variants set out below, which are to be considered individually or according to any technically operative combination.
[0029] Dans un mode de réalisation, pour le chargement ou le transfert de zone l'unité de déclenchement de la prise de photo ou film prend la photo ou film si le premier capteur à diffusion indique la présence d'un passage devant la borne à l'unité de commande, puis le deuxième capteur à diffusion indique un passage devant la borne à l'unité de commande. In one embodiment, for the loading or the zone transfer the unit for triggering the taking of the photo or film takes the photo or film if the first diffusion sensor indicates the presence of a passage in front of the terminal to the control unit, then the second diffusion sensor indicates a passage past the terminal to the control unit.
[0030] Ainsi, il est nécessaire d'avoir un retour des deux capteurs dans cet ordre pour déclencher la prise photo ou film, car il s’agit d'un chargement ou le transfert de zone (entrée ou sortie). [0030] Thus, it is necessary to have feedback from the two sensors in this order to trigger the photo or film taking, because this is a loading or zone transfer (entry or exit).
[0031] Dans un mode de réalisation, pour le déchargement ou le transfert de zone l'unité de déclenchement de la prise de photo ou film prend la photo ou film si le deuxième capteur à diffusion indique un passage devant la borne, puis le deuxième capteur à réflexion indique la présence d'au moins un contenant ou support de contenant, puis le premier capteur à diffusion indique un passage devant la borne, puis le premier capteur à réflexion indique la présence d'au moins un contenant ou support de contenant. In one embodiment, for unloading or zone transfer the unit for triggering the photo or film taking takes the photo or film if the second diffusion sensor indicates a passage in front of the terminal, then the second reflection sensor indicates the presence of at least one container or container support, then the first diffusion sensor indicates a passage in front of the terminal, then the first reflection sensor indicates the presence of at least one container or container support.
[0032] Ainsi, il est nécessaire d'avoir un retour de quatre capteurs dans cet ordre pour déclencher la prise photo ou film, car il s’agit d'un déchargement ou de transfert d'une zone. Ce qui évite les prises de photo ou film intempestives, si par exemple l'opérateur sort du camion sans chargement. [0032] Thus, it is necessary to have a feedback from four sensors in this order to trigger the photo or film taking, because this is an unloading or transfer of an area. This prevents unwanted photo or film taking, if for example the operator leaves the truck without loading.
[0033] Dans un mode de réalisation, il comporte au moins un écran d'information du système. In one embodiment, it comprises at least one system information screen.
[0034] Dans un mode de réalisation, il peut comporter un second écran d'information du système à destination de l'opérateur ou son management lui donnant des informations quantitatives et qualitatives sur le statut du déchargement ou chargement. (Etat d'avancement, respect de consignes de sécurité et de passage, délais, temps, pourcentages etc.) In one embodiment, it may include a second system information screen intended for the operator or his management giving him quantitative and qualitative information on the status of unloading or loading. (State of progress, compliance with safety and transit instructions, deadlines, time, percentages etc.)
[0035] Par exemple, l'écran permet de montrer la photo prise ou film lors du chargement et du déchargement ou transfert de zone d'un contenant ou d'un support de contenant. [0035] For example, the screen makes it possible to show the photo taken or film during the loading and unloading or zone transfer of a container or of a container support.
[0036] Dans un mode de réalisation, de chaque côté du point de passage d'au moins un contenant ou support de contenant se trouve une borne. In one embodiment, on each side of the crossing point of at least one container or container support is a terminal.
[0037] Dans un mode de réalisation, au-dessus du point de passage d'au moins un contenant ou support de contenant se trouve un premier capteur de profondeur adapté à mesurer au moins une distance en hauteur du ou des contenant entre ledit premier capteur et le ou les contenant (s). [0038] Dans un mode de réalisation, de part et d'autre du point de passage d'au moins un contenant ou support de contenant se trouve un deuxième capteur de profondeur et un troisième capteur de profondeur, le deuxième capteur de profondeur et le troisième capteur de profondeur étant adaptés à mesurer au moins une distance en longueur et largeur d'au moins un contenant ou support de contenant entre le deuxième capteur et le ou les contenant(s) ou support de contenant, ou le troisième capteur et le ou les contenant(s) ou support de contenant. In one embodiment, above the point of passage of at least one container or container support is a first depth sensor adapted to measure at least one distance in height of the container or containers between said first sensor and the container (s). In one embodiment, on either side of the passage point of at least one container or container support is a second depth sensor and a third depth sensor, the second depth sensor and the third depth sensor being adapted to measure at least a distance in length and width of at least one container or container support between the second sensor and the container (s) or container support, or the third sensor and the or the container (s) or container support.
[0039] Grâce à ces dispositions, le système permet de déterminer automatiquement le volume en air des contenants sur le support de contenant (dimensions extérieures maximum : longueur, largeur, hauteur), sans arrêt de l'engin manipulant du support de contenant. Thanks to these arrangements, the system makes it possible to automatically determine the volume of air in the containers on the container support (maximum exterior dimensions: length, width, height), without stopping the device handling the container support.
[0040] Lors de la mesure volumétrique, il est nécessaire d'avoir l'information du sens de l'engin manipulant du support de contenant pour enlever le volume de l'engin de manutention et/ou du support de contenant et la personne qui manipule l'engin. Ainsi, les différents capteurs de mesure vont mesurer l'ensemble des contenants et vont pouvoir reconstituer en trois dimensions le volume de l'ensemble. During the volumetric measurement, it is necessary to have the information of the direction of the device handling the container support to remove the volume of the handling device and / or the container support and the person who manipulates the machine. Thus, the various measurement sensors will measure all of the containers and will be able to reconstruct the volume of the assembly in three dimensions.
[0041] L'unité de commande va réaliser un traitement l'information issue des différents capteurs pour soustraire la personne manipulant l'engin et l'engin de manutention pour qu’il reste que le volume des contenants. The control unit will process the information from the various sensors to subtract the person handling the machine and the handling machine so that only the volume of the containers remains.
[0042] Le traitement d'information issu des capteurs est possible en connaissant le sens et la direction du support de contenant, ce qui facilite le calcul du volume pour permettre d'identifier de façon fiable l'engin de manutention et la personne qui le manipule. The processing of information from the sensors is possible by knowing the direction and the direction of the container support, which facilitates the calculation of the volume to allow reliable identification of the handling machine and the person who uses it. manipulate.
[0043] Dans un mode de réalisation, ledit système comporte un terminal communiquant ayant un dispositif de prise de vues et un élément d'envoi desdites prises de vues à ladite base de données. In one embodiment, said system comprises a communicating terminal having a camera device and an element for sending said shots to said database.
[0044] Ainsi, le terminal communiquant est, par exemple : une tablette numérique, un téléphone mobile, notamment de type « smartphone », une montre connectée, des lunettes connectées, un casque, un ordinateur, ou un casque de réalité virtuelle, ou un écran numérique sous toutes ses formes. [0045] Ainsi, il y a des preuves en plus lors du chargement ou déchargement ou du transfert de zone. Thus, the communicating terminal is, for example: a digital tablet, a mobile phone, in particular of the “smartphone” type, a connected watch, connected glasses, a helmet, a computer, or a virtual reality helmet, or a digital screen in all its forms. [0045] Thus, there is additional evidence during loading or unloading or zone transfer.
[0046] Dans un mode de réalisation, le dispositif de prise de vues comporte une information d'horodatage, l'information d'horodatage comportant au moins la date et de l'heure de la prise de vues, ladite information d'horodatage étant transmise à la base de données par l'unité de traitement. In one embodiment, the picture taking device comprises a timestamp information, the timestamp information comprising at least the date and time of the shooting, said timestamp information being transmitted to the database by the processing unit.
[0047] L'information d'horodatage est corrélée à l'opération de chargement ou déchargement ou de transfert de zone des contenants ou supports de contenants concernés. The time-stamping information is correlated with the loading or unloading or zone transfer operation of the containers or container supports concerned.
[0048] L'heure et la date permettent en plus de photo ou film d'attester et de prouver à cet instant ce qui est visible. The time and date allow in addition to a photo or film to attest and to prove at this moment what is visible.

[0074] Exemples de réalisation [0074] Examples of implementation
[0075] La figure 1 représente une borne 20 du système de contrôle de chargement et de déchargement d'un support de contenant. La borne 20 représentée à une hauteur d'environ 1 ,50 m et est placée à proximité du point de passage des supports de contenant (quai de chargement /déchargement d'un entrepôt, portes d'entrées/sorties de stock). FIG. 1 represents a terminal 20 of the system for controlling the loading and unloading of a container support. The terminal 20 shown at a height of approximately 1.50 m and is placed near the point of passage of the container supports (loading / unloading dock of a warehouse, stock entry / exit doors).
[0076] Le système intègre principalement une caméra (dispositif de prise de vues, 21), un flash 22, un ordinateur ou microcontrôleur ou automate ou encore unité de commande, des cellules de détection des contenants ou supports de contenant. La première cellule de détection des contenants ou supports de contenant comporte un premier capteur à diffusion 23 et la deuxième cellule de détection des contenants ou supports de contenant comporte un deuxième capteur à diffusion 24. Au niveau de la borne 20 se trouve un écran 25 permettant l'affichage d'information. Au-dessus de la borne 20 se trouve un témoin de passage 26 lumineux, (des voyants) The system mainly integrates a camera (shooting device, 21), a flash 22, a computer or microcontroller or automaton or even control unit, cells for detecting the containers or container supports. The first cell for detecting the containers or container supports comprises a first diffusion sensor 23 and the second The container detection cell or container supports comprises a second diffusion sensor 24. At terminal 20 is a screen 25 allowing information to be displayed. Above terminal 20 is an illuminated passage indicator 26, (indicator lights)
[0077] Le système offre les fonctionnalités suivantes : The system offers the following functionalities:
[0078] - Prise de photos ou films sous différents angles au moment précis du passage du ou des contenants ou supports de contenant, permettant leur reconstitution volumique et leur identification ou la visualisation de leur état à cet instant. Taking photos or films from different angles at the precise moment of passage of the container (s) or container supports, allowing their volume reconstitution and their identification or the visualization of their state at this moment.
[0079] - Récupération du code barre d'identification du ou des contenants ou supports de contenant par analyse d'image. - Recovery of the identification bar code of the container (s) or container supports by image analysis.
[0080] - Echange informatique avec le logiciel de gestion d'entrepôt (ERP, WMS,[0080] - Computer exchange with warehouse management software (ERP, WMS,
TMS) du client pour validation du mouvement du support de contenant ou contenant. TMS) from the customer for validation of the movement of the container or container support.
[0081] - Archivage des photos et films pour preuve d'expédition/réception. [0081] - Archiving of photos and films for proof of shipment / receipt.
[0082] - Discrimination chargement ou déchargement, entrée et sortie de zone, pour éviter les déclenchements intempestifs de photos ou films (passage à vide, passage d'un opérateur seul). - Discrimination of loading or unloading, entry and exit of a zone, to avoid untimely triggering of photos or films (empty passage, passage of a single operator).
[0083] Un des problèmes résolus par l'invention consiste à garantir le déclenchement d'une ou plusieurs photos ou films au moment exact du passage du contenant ou du support de contenant devant la borne 20. One of the problems solved by the invention consists in guaranteeing the triggering of one or more photos or films at the exact moment of the passage of the container or of the container support in front of the terminal 20.
[0084] Mode chargement du contenant ou du support de contenant (marche avant du système de manutention) : Loading mode of the container or the container support (forward movement of the handling system):
[0085] Pour ce cas de figure, l'idée originale consiste à utiliser deux cellules de détection de contenant ou du support de contenant (à réflexion directe) permettant de déterminer le sens de passage (une cellule puis l'autre), de mesurer le temps entre les deux détections, calculer la vitesse de passage et déclencher la photo ou film au moment précis du passage d'un contenant ou du support de contenant. L'usage d'un troisième capteur permet par ailleurs le calcul de l'accélération en plus de la vitesse. For this scenario, the original idea is to use two container detection cells or the container support (direct reflection) to determine the direction of passage (one cell then the other), to measure the time between the two detections, calculate the speed of passage and trigger the photo or film at the precise moment of the passage of a container or the container support. The use of a third sensor also makes it possible to calculate the acceleration in addition to the speed.
[0086] Lors de la sortie du chariot vide (sans support de contenant), les cellules détectent l'ordre de passage et inhibent le déclenchement de photo ou film. [0087] Les cellules sont positionnées à environ 30 cm du sol de façon à pouvoir détecter un contenant ou un support de contenant les plus bas. When leaving the empty cart (without container support), the cells detect the order of passage and inhibit the triggering of a photo or film. The cells are positioned about 30 cm from the ground so as to be able to detect a container or a lower container support.
[0088] La figure 2 représente un schéma du passage d'un support de contenant devant une borne 20 du système de contrôle de chargement et de déchargement ou de transfert de zone d'un support de contenant. FIG. 2 represents a diagram of the passage of a container support in front of a terminal 20 of the loading and unloading control system or of zone transfer of a container support.
[0089] La mise en œuvre du système se traduit par l'installation de bornes 20 au niveau de quai de chargement de camions, il s'agit également de l'installation de bornes 20 au niveau de portes d'accès à des stocks (exemple : produits ou marchandises sortant de production sur un support de contenant ou un contenant et stockés ensuite dans un entrepôt intégré au site, le transfert se fait par chariot élévateur). The implementation of the system results in the installation of terminals 20 at the level of the truck loading dock, it is also the installation of terminals 20 at the level of access doors to stocks ( example: products or goods leaving production on a container support or a container and then stored in a warehouse integrated on the site, the transfer is done by forklift).
[0090] Les bornes peuvent être fixées au sol, ou sur un support mobile en position arrêt lors des déclenchements, ou fixées au plafond sans prise de surface au sol, ou fixées à un mur ou type de support fixe permettant de les supporter de manière stable et immobile au moment du ou des déclenchements. The bollards can be fixed to the ground, or on a mobile support in the off position when triggering, or fixed to the ceiling without taking a surface on the ground, or fixed to a wall or type of fixed support allowing them to be supported in a manner stable and immobile at the time of the trigger (s).
[0091] La géométrie du système global peut être déstructuré pour épouser la géométrie du passage des contenants ou supports de contenantsThe geometry of the overall system can be deconstructed to match the geometry of the passage of the containers or container supports.
[0092] Cette figure montre une seule borne 20 qui est installée à chaque point de contrôle (nécessite la présence de l'étiquette sur un contenant ou un support de contenant toujours du même côté). Un écran 25 se trouve sur la borne 20 et un autre qui est positionné au-dessus du quai de chargement ou de déchargement. L'écran 25 de grande taille est déporté en hauteur et permet de faire un retour à l'opérateur. This figure shows a single terminal 20 which is installed at each control point (requires the presence of the label on a container or a container support always on the same side). A screen 25 is located on terminal 20 and another which is positioned above the loading or unloading dock. The large screen 25 is offset in height and allows the operator to return.
[0093] Les deux traits en pointillés représentent le cône de vue du dispositif de prise de vues 21. La flèche indique le sens de passage du support de contenant. The two dotted lines represent the cone of view of the shooting device 21. The arrow indicates the direction of passage of the container support.
[0094] En cas d'incertitude de la position de l'étiquette (code barre) sur du support de contenant, il est positionné deux bornes 20 installées de chaque côté du point de contrôle (une borne « maître » + une borne « esclave »). En cas de mise en place des étiquettes sur une autre face visible (dessus ou face), une borne additionnelle d'une borne est effectuée au-dessus ou face au passage. [0095] Les figures 3 à 7 représentent des schémas du passage du support de contenant devant une borne 20 du système de contrôle lors du chargement d'un support de contenant. Sur ces figures, il est représenté la borne 20, un premier capteur de diffusion 23 et un deuxième capteur de diffusion 24. In case of uncertainty of the position of the label (bar code) on the container support, two terminals 20 installed on each side of the control point are positioned (a "master" terminal + a "slave" terminal "). If the labels are placed on another visible face (top or face), an additional bollard of a bollard is made above or facing the passage. Figures 3 to 7 show diagrams of the passage of the container support in front of a terminal 20 of the control system when loading a container support. In these figures, terminal 20 is shown, a first diffusion sensor 23 and a second diffusion sensor 24.
[0096] La figure 3 représente l'arrivée d'un support de contenant devant la zone de d'identification. FIG. 3 represents the arrival of a container support in front of the identification zone.
[0097] La détection est effectuée par la première cellule qui comporte le premier capteur de diffusion 23. Celui-ci est coupé par le passage du support de contenant. The detection is performed by the first cell which comprises the first diffusion sensor 23. The latter is cut by the passage of the container support.
[0098] La figure 4 représente l'arrivée du support de contenant devant la zone de d'identification et détection par la deuxième cellule. FIG. 4 represents the arrival of the container support in front of the identification and detection zone by the second cell.
[0099] La détection est effectuée par la première cellule de détection qui comporte le premier capteur de diffusion 23 et le deuxième capteur de diffusion 24. La détection est alors effectuée par le premier capteur de diffusion 23 qui est coupé par un passage devant la borne, puis le deuxième capteur à diffusion 24 qui est également coupé par un passage devant la borne. The detection is carried out by the first detection cell which comprises the first diffusion sensor 23 and the second diffusion sensor 24. The detection is then carried out by the first diffusion sensor 23 which is cut by a passage in front of the terminal , then the second diffusion sensor 24 which is also cut by a passage in front of the terminal.
[00100] L'unité de commande traite l'i nformation en directe et calcule la vitesse de déplacement du support de contenant. L'information de la vitesse est alors traitée par l'unité de déclenchement de la prise de photo ou film pour déclencher la photo ou film au bon moment. La photo ou film est prise si le premier capteur à diffusion 23 indique un passage devant la borne 20 à l'unité de commande puis le deuxième capteur à diffusion 24 indique un passage devant la borne 20 à l'unité de commande. Dans une autre variante, la photo ou film est prise en fonction de la vitesse d'avance du support de contenant et si le premier capteur à diffusion 23 indique un passage devant la borne 20 à l'unité de commande puis le deuxième capteur à diffusion 24 indique un passage devant la borne 20 à l'unité de commande. The control unit processes the direct information and calculates the speed of movement of the container support. The speed information is then processed by the photo or film triggering unit to trigger the photo or film at the right time. The photo or film is taken if the first diffusion sensor 23 indicates a passage past terminal 20 to the control unit and then the second diffusion sensor 24 indicates a passage past terminal 20 to the control unit. In another variant, the photo or film is taken as a function of the speed of advance of the container support and if the first diffusion sensor 23 indicates a passage in front of terminal 20 to the control unit then the second diffusion sensor 24 indicates a passage past terminal 20 to the control unit.
[00101] La figure 5 représente le déclenchement de la photo ou film centré sur le support de contenant. [00101] FIG. 5 represents the triggering of the photo or film centered on the container support.
[00102] Il est visible un cône qui représente la prise de vues par le dispositif de prise de vues 21. L'unité de déclenchement de la prise de photo ou film déclenche la prise de photo ou film lorsque le support de contenant se trouve au milieu du cône représenté sur la figure. Le milieu est connu par la vitesse de déplacement du support de contenant. Les dimensions du support de contenant sont connues, le prise de photo ou film est déclenchée légèrement (en fonction de la vitesse) après que les sorties du premier capteur à diffusion 23 et du deuxième capteur à diffusion 24 indique un passage devant la borne 20. L'ordre de coupure du premier capteur à diffusion 23 puis du deuxième capteur à diffusion 24 indique bien le chargement et donc la prise de photo ou film pour le chargement ou transfert de zone. It is visible a cone which represents the taking of pictures by the picture taking device 21. The unit for triggering the taking of the photo or film triggers the taking of the photo or film when the container support is at the environment of the cone shown in the figure. The medium is known by the speed of movement of the container support. The dimensions of the container support are known, the photo or film taking is triggered slightly (depending on the speed) after the outputs of the first diffusion sensor 23 and of the second diffusion sensor 24 indicate a passage in front of the terminal 20. The cut-off order of the first diffusion sensor 23 then of the second diffusion sensor 24 clearly indicates the loading and therefore the taking of a photo or film for the loading or transfer of the zone.
[00103] La figure 6 représente le chargement du support de contenant dans le camion ou transfert dans la zone. Sur cette figure le support de contenant est chargée dans le camion. Le premier capteur de diffusion 23 et le deuxième capteur de diffusion 24 n'étant pas coupé par le support de contenant ou par son engin de manutention. [00103] FIG. 6 represents the loading of the container support in the truck or transfer to the area. In this figure the container support is loaded into the truck. The first diffusion sensor 23 and the second diffusion sensor 24 not being cut by the container support or by its handling device.
[00104] La figure 7 représente la sortie du chariot (engin de manutention) du camion. [00104] FIG. 7 represents the exit of the carriage (handling equipment) of the truck.
[00105] Sur cette figure le support de contenant est stocké dans le camion et on voit l'engin de manutention sortir du camion. La détection de l'engin de manutention est effectuée de la manière suivante : détection par le deuxième capteur de diffusion 24 puis par le premier capteur de diffusion 23. Dans cet ordre de détection il n'y a pas de déclenchement photo ou film. Autrement dit, lorsque le deuxième capteur à diffusion 24 est coupé puis le premier capteur à diffusion 23, l'unité de déclenchement de prise de photo ou film ne prend pas de photo ou film. In this figure the container support is stored in the truck and we see the handling machine out of the truck. The handling machine is detected as follows: detection by the second diffusion sensor 24 then by the first diffusion sensor 23. In this detection order there is no photo or film trigger. In other words, when the second diffusion sensor 24 is cut and then the first diffusion sensor 23, the photo or film taking trigger unit does not take a photo or film.
[00106] Mode déchargement du support de contenant (marche arrière du système de manutention) : [00106] Unloading mode of the container support (reverse of the handling system):
[00107] Pour ce cas de figure, il est détecté en premier le système de manutention et certainement l'opérateur s’il s’agit d'un transpalette électrique ou manuel. [00107] For this scenario, the handling system is first detected and certainly the operator if it is an electric or manual pallet truck.
[00108] L'idée originale consiste à utiliser deux cellules de détection supplémentaires sensibles uniquement à des réflecteurs fixés sur l'engin de manutention et calculer le point de déclenchement de la photo ou film à l'aide de ces deux cellules. [00109] Les figures 8 à 11 représentent des schémas du passage du support de contenant devant une borne 20 du système de contrôle lors du déchargement du support de contenant. Sur ces figures, il est représenté la borne 20, un premier capteur de diffusion 23, un deuxième capteur de diffusion 24, premier capteur à réflexion 27 et deuxième capteur à réflexion 28. The original idea consists in using two additional detection cells sensitive only to reflectors attached to the handling machine and to calculate the trigger point of the photo or film using these two cells. Figures 8 to 11 show diagrams of the passage of the container support in front of a terminal 20 of the control system during unloading of the container support. In these figures, terminal 20 is shown, a first diffusion sensor 23, a second diffusion sensor 24, first reflection sensor 27 and second reflection sensor 28.
[00110] La figure 8 représente l'arrivée devant la zone d'identification et la détection de l'opérateur. Sur cette figure le support de contenant est déchargé dans le camion. Le deuxième capteur à diffusion 24 est coupée ainsi que le deuxième capteur à réflexion 28. Toutefois, à cette étape le deuxième capteur à réflexion 28 ne renvoie pas l'information de la réflexion puisque le réflecteur est sur l'engin de manutention. L'opérateur passe devant les cellules de détection sans les déclencher. FIG. 8 represents the arrival in front of the identification zone and the detection of the operator. In this figure, the container support is unloaded into the truck. The second diffusion sensor 24 is cut as well as the second reflection sensor 28. However, at this stage, the second reflection sensor 28 does not return the reflection information since the reflector is on the handling machine. The operator walks past the detection cells without triggering them.
[00111] La figure 9 représente la détection de l'engin de manutention. L'engin de manutention est détecté par le deuxième capteur à réflexion 28. En l'espèce, le réflecteur positionné sur engin de manutention donne l'information du passage devant la borne 20. Le premier capteur à réflexion 27 n'est pas coupé, il n'y a pas encore de détection de l'engin de manutention. Le premier capteur à diffusion 23 est coupé par l'engin de manutention. Le système enregistre l'ordre de déclenchement des capteurs de sorte à pouvoir identifier le chargement du déchargement. [00111] FIG. 9 represents the detection of the handling device. The handling machine is detected by the second reflection sensor 28. In this case, the reflector positioned on the handling machine gives the information of the passage in front of the terminal 20. The first reflection sensor 27 is not cut, the handling machine has not yet been detected. The first diffusion sensor 23 is cut by the handling machine. The system records the triggering order of the sensors so that the loading of the unloading can be identified.
[00112] La figure 10 représente la détection de l'engin de manutention par le premier capteur à réflexion 27. L'engin de manutention est détecté par le premier capteur à réflexion 27 coopérant avec le réflecteur positionné sur l'engin de manutention. FIG. 10 shows the detection of the handling device by the first reflection sensor 27. The handling device is detected by the first reflection sensor 27 cooperating with the reflector positioned on the handling device.
[00113] La figure 11 représente la prise de photos ou films. Les photos ou films sont prises uniquement s’il y a présence du support de contenant ou du contenant. L'unité de déclenchement de la prise de photos ou films permet la prise de photos ou films si le deuxième capteur à diffusion 24 est coupé ou indique le passage devant la borne 20, puis le deuxième capteur à réflexion 28 est coupé ou indique la présence du support de contenant ou du contenant, puis le premier capteur à diffusion 23 est coupé ou indique la présence devant la borne 20 et enfin si le deuxième capteur à réflexion 28 indique la présence du contenant ou du support de contenant. Le principe d'utilisation de quatre cellules de détection permet de détecter automatiquement s’il s’agit d'un chargement ou d'un déchargement et l'engin de manutention vide n'est jamais pris en photo ou film. [00113] FIG. 11 represents the taking of photos or films. Photos or films are taken only if the container support or container is present. The photo or film triggering unit allows photos or films to be taken if the second diffusion sensor 24 is cut or indicates the passage in front of terminal 20, then the second reflection sensor 28 is cut or indicates the presence of the container support or of the container, then the first diffusion sensor 23 is cut or indicates the presence in front of the terminal 20 and finally if the second reflection sensor 28 indicates the presence of the container or the container support. The principle of using four detection cells makes it possible to automatically detect whether it is a loading or unloading and the empty handling machine is never photographed or filmed.
[00114] Mesure de volume lors du passage d'un contenant ou d'un support de contenant Volume measurement during the passage of a container or a container support
[00115] Le système permet de déclencher un évènement lors du passage précis de d'un contenant ou d'un support de contenant, par exemple lors du chargement ou du déchargement d'un camion. The system makes it possible to trigger an event during the precise passage of a container or a container support, for example during the loading or unloading of a truck.
[00116] Le système comprend pour la mesure du volume des capteurs de profondeur. Ces capteurs renvoient une matrice de points contenant chacun la distance entre le capteur et l'objet potentiel. The system comprises depth sensors for measuring the volume. These sensors return a matrix of points each containing the distance between the sensor and the potential object.
[00117] La figure 12 permet de voir la mesure avec un capteur de profondeur situé au-dessus d'un support de contenant. FIG. 12 makes it possible to see the measurement with a depth sensor located above a container support.
[00118] Cette vue de dessus permet de récupérer au moins une distance en hauteur du contenant ou d'un support de contenant. This top view makes it possible to recover at least a distance in height from the container or from a container support.
[00119] La figure 13 permet de voir avec un capteur de profondeur situé au-dessus d'au moins un contenant et deux autres sur le côté afin d'obtenir une mesure exhaustive des dimensions du contenant ou du support de contenant. Les capteurs de profondeur étant positionnés sur un portique au-dessus du passage d'un contenant ou du support de contenant. Ce système permet de prendre une photo ou un film et de mesurer le volume du contenant ou du support de contenant. FIG. 13 makes it possible to see with a depth sensor located above at least one container and two others on the side in order to obtain an exhaustive measurement of the dimensions of the container or of the container support. The depth sensors being positioned on a gantry above the passage of a container or the container support. This system allows you to take a photo or film and measure the volume of the container or container support.
[00120] Afin d'effectuer une mesure exhaustive en récupérant une pluralité de la longueur et la largeur, il y a deux capteurs de profondeurs supplémentaires positionnés de chaque côté légèrement au-dessus de chaque borne 20. Un microcontrôleur permet à l'aide d'un algorithme de traitement des mesures de reconstruire une vision en trois dimensions des trois mesures effectuées du contenant ou du support de contenant et d'en extraire les dimensions extérieures maximum. In order to perform an exhaustive measurement by retrieving a plurality of the length and the width, there are two additional depth sensors positioned on each side slightly above each terminal 20. A microcontroller allows using a measurement processing algorithm to reconstruct a three-dimensional view of the three measurements made of the container or of the container support and to extract the maximum external dimensions therefrom.
[00121] Les figures 14 et 15 montrent une visualisation en trois dimensions sous deux angles différents. Ces figures montrent un nuage de point représentant la mesure effectuée par les capteurs de profondeurs. A l'aide de l'unité de commande, le volume est déduit de ces mesures. Les trois dimensions hauteur, largeur et longueur étant extraite de ces mesures de profondeur. Figures 14 and 15 show a three-dimensional view from two different angles. These figures show a point cloud representing the measurement made by the depth sensors. Help of the control unit, the volume is deduced from these measurements. The three dimensions height, width and length being taken from these depth measurements.
[00122] Dans un exemple, il existe plusieurs paquets rectangulaires. Pour chacun des paquets il est déduit les dimensions et le volume est ensuite calculé en additionnant les différents paquets. [00122] In one example, there are several rectangular packages. For each of the packages, the dimensions are deduced and the volume is then calculated by adding the different packages.
Dans l'exemple représenté, on ne distingue pas les paquets un à un, le calcul du volume n'est pas la résultante du volume de chaque paquet mais une mesure globale. In the example shown, the packets are not distinguished one by one, the calculation of the volume is not the result of the volume of each packet but an overall measurement.
