Description

Certains engins mobiles motorisés tels que par exemple des ponts roulants, comportent un récepteur à liaison hertzienne agissant sur les commandes de l'engin mobile auquel il est combiné, de façon que ce dernier puisse être actionné à distance à partir d'un émetteur portable manipulé par un ouvrier.Certain mobile motorized vehicles such as, for example, overhead traveling cranes, include a radio link receiver acting on the controls of the mobile vehicle with which it is combined, so that the latter can be operated remotely from a manipulated portable transmitter. by a worker.

Ce système de liaison est pratique et est très répandu dans l'industrie. Néanmoins, si la procédure d'utilisation n'est pas respectée, on peut craindre des anomalies de fonctionnement de l'installation.This connection system is practical and is widely used in the industry. However, if the operating procedure is not followed, there is a risk of operating faults in the installation.

Ainsi, non seulement l'émetteur peut être manipulé par mégarde sans que l'on puisse le constater immédiatement mais encore une manipulation de l'émetteur, hors visibilité de l'engin mobile, par exemple d'un bureau voisin, peut entraîner une mise en marche incontrôlée du pont.Thus, not only can the transmitter be manipulated inadvertently without being immediately visible, but also manipulation of the transmitter, out of sight of the mobile device, for example from a neighboring office, can lead to a setting uncontrolled movement of the bridge.

Egalement, lorsqu'un atelier comporte plusieurs ponts travaillant l'un à côté de l'autre, qui sont commandés par des émetteurs différents mais qui se ressemblent tous, l'opérateur peut, par erreur, utiliser un émetteur portable dont le code ne correspond pas au pont qu'il désire actionner, si bien qu'il va mettre en route de manière incontrôlée le pont mobile d'une travée adjacente avec les risques importants d'accidents qui en découlent.Also, when a workshop has several bridges working side by side, which are controlled by different transmitters but which all look the same, the operator may, by mistake, use a portable transmitter whose code does not correspond not at the bridge he wants to operate, so well that it will start up in an uncontrolled manner the mobile bridge of an adjacent span with the significant risks of accidents which ensue therefrom.

La présente invention a notamment pour but de remédier à ces inconvénients et concerne à cet effet une installation pour la télécommande par liaison hertzienne d'un engin mobile motorisé comprenant un récepteur à fréquence radio installé sur l'engin mobile auquel il est combiné de façon à assurer la télécommande de cet engin à partir d'un émetteur à fréquence radio portable correspondant, installation caractérisée en ce que l'engin mobile comporte également un émetteur infrarouge tandis que l'émetteur portable comporte un récepteur infrarouge correspondant, ces émetteur et récepteur infrarouges étant combinés aux récepteur et émetteur à fréquence radio de façon que, au moins la mise en route de l'engin mobile, ne puisse être effectuée par la télécommande par liaison hertzienne, depuis l'émetteur portable, que lorsque cet émetteur portable se trouve dans une zone telle, par rapport à l'engin mobile, qu'il peut recevoir préalablement un signal à fréquence infrarouge d'autorisation de télécommande.The object of the present invention is in particular to remedy these drawbacks and for this purpose relates to an installation for the remote control by radio link of a motorized mobile vehicle comprising a radio frequency receiver installed on the mobile vehicle to which it is combined so as to ensure the remote control of this machine from a corresponding portable radio frequency transmitter, installation characterized in that the mobile machine also includes an infrared transmitter while the portable transmitter includes a corresponding infrared receiver, these infrared transmitter and receiver being combined with radio frequency receiver and transmitter so that, at least the start-up of the mobile device, can only be carried out by radio remote control, from the portable transmitter, only when this portable transmitter is in a area such that, relative to the mobile device, it can receive a signal beforehand infrared remote control authorization.

L'invention est représentée à titre d'exemple non limitatif sur l'unique dessin ci-joint qui est une vue schématique d'une installation pour la télécommande par liaison hertzienne d'un pont roulant.The invention is shown by way of nonlimiting example in the single attached drawing which is a schematic view of an installation for the remote control by radio link of an overhead crane.

La présente invention a en conséquence pour but d'augmenter le niveau de sécurité dans le système de télécommande d'un engin mobile motorisé tout en bénéficiant des avantages d'une liaison hertzienne. L'installation est à cet effet réalisée de telle manière que la télécommande par liaison hertzienne ne puisse être opérée (mise en route ou activation d'un processus d' "homme mort") que lorsque la manipulation de télécommande est effectuée à proximité immédiate ou tout au moins dans une zone délimitée, de l'engin mobile motorisé.The present invention therefore aims to increase the level of security in the remote control system of a mobile motorized vehicle while benefiting from the advantages of a radio link. To this end, the installation is carried out in such a way that the remote control by radio link can only be operated (start-up or activation of a "dead man" process) when the manipulation remote control is carried out in the immediate vicinity or at least in a delimited area, of the mobile motorized vehicle.

Ainsi, sur la figure ci-jointe, cet engin mobile motorisé est constitué par un pont roulant dont le chariot 1 se déplace sur des rails 2 à l'aide de roues motrices 3, ce pont roulant supportant un palan 4 actionné par un treuil moteur 5.Thus, in the attached figure, this mobile motorized vehicle is constituted by an overhead crane, the carriage 1 of which moves on rails 2 using drive wheels 3, this overhead crane supporting a hoist 4 actuated by a motor winch 5.

Tous ces engins moteurs sont actionnés par l'intermédiaire de relais à partir d'un boîtier 6 qui constitue un récepteur radio dont l'organe de réception est constitué par l'antenne 7.All these traction units are actuated by means of relays from a box 6 which constitutes a radio receiver, the receiving member of which is constituted by the antenna 7.

L'actionnement de ces organes moteurs 3, 5 par l'intermédiaire du boîtier du récepteur à fréquence radio 6, est assuré par un émetteur portable inclus dans un boîtier 8 et dont l'antenne émettrice est schématisée en 9.The actuation of these motor members 3, 5 via the radio frequency receiver box 6, is ensured by a portable transmitter included in a box 8 and whose transmitting antenna is shown diagrammatically at 9.

Cette liaison à fréquence radio illustrée en 10 permet donc, à partir de l'actionnement des boutons de commande 8₁ du boîtier 8 de commander les divers organes moteurs du chariot 1 du pont roulant afin d'effectuer les manoeuvres désirées.This radio frequency link illustrated in 10 therefore allows, from the actuation of the control buttons 8₁ of the housing 8 to control the various motor members of the carriage 1 of the overhead crane in order to perform the desired maneuvers.

Conformément à l'invention, le chariot 1 de l'engin mobile motorisé comporte également un émetteur infrarouge dont l'organe d'émission est schématisé en 11 et est, de préférence, disposé sur le boîtier 6 du récepteur à fréquence radio. L'organe d'émission infrarouge 11 du récepteur radio du boîtier 6 émet un faisceau directionnel délimité simple ou multiple et éventuellement d'orientation réglable, orienté de manière convenable.According to the invention, the carriage 1 of the motorized mobile vehicle also includes an infrared transmitter, the transmission member of which is shown diagrammatically at 11 and is preferably placed on the housing 6 of the radio frequency receiver. The infrared emitting member 11 of the radio receiver of the box 6 emits a single or multiple delimited directional beam and possibly of adjustable orientation, oriented in a suitable manner.

Dans l'exemple représenté, l'engin mobile motorisé étant constitué par un pont roulant, l'organe d'émission infrarouge est orienté vers le sol et le récepteur infrarouge correspondant est inclus au boîtier 8 de l'émetteur portable à fréquence radio de façon que l'organe de réception infrarouge 12 n'autorise la télécommande du chariot 1 par la liaison hertzienne 10 que lorsque le boîtier portable 8, c'est-à-dire en fait l'ouvrier qui le manipule, est situé dans la zone parfaitement délimitée 11₁ dans laquelle est émis le signal infrarouge provenant de l'organe émetteur 11 du boîtier 6.In the example shown, the mobile motorized vehicle being constituted by an overhead crane, the infrared emission member is oriented towards the ground and the corresponding infrared receiver is included in the box 8 of the portable radio frequency transmitter so that the infrared receiving member 12 authorizes the remote control of the carriage 1 by the radio link 10 only when the portable box 8, that is to say in fact the the worker who manipulates it is located in the perfectly delimited zone 11₁ in which the infrared signal emitted by the emitting member 11 of the housing 6 is emitted.

La combinaison dans le boîtier portable 8 de l'émetteur à fréquence radio et du récepteur infrarouge est telle que au moins la mise en route de l'un des organes moteurs de l'engin mobile ne puisse être effectuée par la liaison hertzienne que lorsque ce boîtier 8 de l'émetteur portable se trouve dans une zone telle, par rapport à l'engin mobile 1, qu'il peut recevoir préalablement un signal à fréquence infrarouge d'autorisation de télécommande.The combination in the portable box 8 of the radio frequency transmitter and the infrared receiver is such that at least the starting of one of the motor organs of the mobile machine can only be carried out by the radio link when this box 8 of the portable transmitter is in an area such, relative to the mobile machine 1, that it can receive beforehand an infrared frequency signal for remote control authorization.

En effet, on peut considérer que lorsque l'ouvrier se trouve dans la zone 11₁, au début d'une télécommande de mouvements de l'engin mobile 1 il pourra ensuite modifier ses instructions de commande de l'engin mobile à partir du boîtier 8 sans qu'il se trouve obligatoirement dans la zone 11₁ d'émission du faisceau infrarouge et cela tant que les organes moteurs de l'engin mobile 1 n'ont pas été totalement arrêtés.Indeed, it can be considered that when the worker is in zone 11₁, at the start of a remote control of movements of the mobile machine 1 he can then modify his instructions for controlling the mobile machine from the housing 8 without it being necessarily in the zone 11₁ of emission of the infrared beam and this as long as the driving members of the mobile machine 1 have not been completely stopped.

L'objectif essentiel de cette liaison infrarouge entre le récepteur à fréquence radio prévu sur l'engin mobile et l'émetteur à fréquence radio du boîtier portable, est avant tout d'augmenter le niveau de sécurité lors de la prise de contrôle de l'engin mobile par l'opérateur de la télécommande. Cette liaison infrarouge pourra cependant être utilisée à d'autres fins et, en particulier, pour le retour d'informations de l'engin mobile vers l'opérateur (indication de charge, surveillance technique, etc.) de façon que ces informations puissent être vérifiées par l'opérateur au début de chaque manipulation.The main objective of this infrared link between the radio frequency receiver provided on the mobile device and the radio frequency transmitter of the portable unit, is above all to increase the level of security when taking control of the mobile machine by the operator of the remote control. This infrared link may however be used for other purposes and, in particular, for the return of information from the mobile machine to the operator. (load indication, technical monitoring, etc.) so that this information can be checked by the operator at the start of each operation.
