Description

SYSTEME DE SECURITE ET DE PROTECTION INDUSTRIELLE SECURITY AND INDUSTRIAL PROTECTION SYSTEM
La présente invention a pour objet un système de sécurité et de protection industrielle.The present invention relates to a security and industrial protection system.
11 concerne en particulier la sécurité du personnel utilisateur de machines outils ou de systèmes industriels dangereux, dans tous les cas où le port de dispositifs de protection corporelle telles que lunettes est préconisé, mais il peut également trouver des applications diverses telles que la sécurité des motocyclistes. Les dispositifs réalisés à ce jour, soit sont peu efficaces et faciles à prendre en défaut, soit sont peu agréables à utiliser. Par exemple, le brevet français 2 354 506 décrit un système de sécurité destiné aux machines projetant des particules telles que meules, dans lequel la mise en route de la machine ne peut se faire que si l'on a retiré des lunettes de protection d'un boîtier. Mais rien n'oblige l'opérateur à porter lesdites lunettes. L'objet de la présente invention supprime tous ces inconvénients. En effet, il n'autorise le fonctionnement de la machine que si la protection corporelle est effectivement portée par l'opérateur. Il est constitué par la combinaison d'un dispositif de protection muni d'un moyen de détection né pouvant être activés que par le contact avec la peau de l'opérateur, le dispositif de protection comportant un émetteur intégré et autonome transmettant par un signal haute fréquence des informations codées à un récepteur ne permettant la mise en route de la machine ou de l'équipement industriel que lorsque le signal reçu correspond à l'activation dudit moyen de détection.It relates in particular to the safety of personnel using machine tools or dangerous industrial systems, in all cases where the wearing of body protection devices such as glasses is recommended, but it can also find various applications such as the safety of motorcyclists . The devices produced to date either are ineffective and easy to fault, or are unpleasant to use. For example, French patent 2,354,506 describes a safety system intended for machines projecting particles such as grindstones, in which the machine can only be started if protective glasses have been removed. a housing. But nothing obliges the operator to wear said glasses. The object of the present invention eliminates all these drawbacks. Indeed, it authorizes the operation of the machine only if the body protection is actually worn by the operator. It consists of the combination of a protection device provided with a means of detection which can be activated only by contact with the operator's skin, the protection device comprising an integrated and autonomous transmitter transmitting by a high signal. frequency of information coded at a receiver enabling the machine or the industrial equipment to be started only when the received signal corresponds to the activation of said detection means.
Sur les dessins annexés, donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention : La figure 1 représente des lunettes de protection équipées du dispositif selon la présente invention. La figure 2 est le schéma synoptique de l'émetteur intégré. La figure 3 est le schéma synoptique du récepteur. Le dispositif, figure 1 à 3, est constitué de lunettes de protection 1 équipées d'un émetteur A et d'un récepteur 5 contrôlant la mise en marche du moteur 16 de la machine. Les lunettes de protection 1 comportent deux zones conductrices 2, 3 entrant en contact avec la peau de l'opérateur lorsqu'elles sont effectivement portées. Ces zones conductrices sont conçues de telle manière qu'elles ne puissent être reliées électriquement en posant simplement les lunettes 1 sur une surface métallique, par exemple. Ce résultat est obtenu en disposant au moins l'une de ces zones conductrices dans un renfoncement du dispositif de protection, ce qui est le cas de la zone 3 portant sur le nez dans le cas des lunettes de protection courantes. Les zones conductrices 2 et 3 forment un détecteur résistif ou capacitif. Dans une variante de réalisation, les zones conductrices 2, 3 sont remplacées par un ou plusieurs micro-contacts. L'émetteur intégré L, est de type miniaturisé à faible consommation. Il comporte un circuit 6 de type "trigger" relié aux zones conduc- trices et basculant dans un état actif lorsqu'elles sont en contact avec la peau. Ce circuit est relié à un module de gestion de l'émission 7 qui active un circuit 8 générant les informations codées qui sont transmises à l'émetteur haute fréquence 9 propre¬ ment dit. L'ensemble est alimenté par une pile miniature 10 incorporée.In the accompanying drawings, given by way of nonlimiting example of one of the embodiments of the subject of the invention: FIG. 1 represents protective glasses fitted with the device according to the present invention. Figure 2 is the block diagram of the integrated transmitter. Figure 3 is the block diagram of the receiver. The device, FIGS. 1 to 3, consists of protective glasses 1 equipped with a transmitter A and a receiver 5 controlling the starting of the motor 16 of the machine. The protective glasses 1 comprise two conductive zones 2, 3 coming into contact with the operator's skin when they are actually worn. These conductive areas are designed in such a way that they cannot be electrically connected by simply placing the spectacles 1 on a metal surface, for example. This result is obtained by placing at least one of these conductive zones in a recess of the protection device, which is the case of zone 3 on the nose in the case of current protective glasses. The conductive zones 2 and 3 form a resistive or capacitive detector. In an alternative embodiment, the conductive zones 2, 3 are replaced by one or more micro-contacts. The integrated transmitter L, is of miniaturized type with low consumption. It includes a circuit 6 of the "trigger" type connected to the conducting zones and switching to an active state when they are in contact with the skin. This circuit is connected to a transmission management module 7 which activates a circuit 8 generating the coded information which is transmitted to the high frequency transmitter 9 proper. The assembly is powered by a built-in miniature battery 10.
Le récepteur 5 est- constitué d'un circuit haute fréquence 11, suivi d'un module d'analyse des informations 12 et d'une base de temps 13 permettant d'activer un bloc de commande de commu¬ tation la qui contrôle la marche du moteur 16 de la machine par l'intermédiaire d'un étage de puissance 15. Le tout étant complété par une alimentation basse tension 17.The receiver 5 is made up of a high frequency circuit 11, followed by an information analysis module 12 and a time base 13 making it possible to activate a commu¬ tation command block 1a which controls the operation of the engine 16 of the machine via a power stage 15. The whole being supplemented by a low voltage supply 17.
L'émetteur 4 d'ondes haute fréquence transmet des informations codées qui ne peuvent pas être perturbées ou brouillées par les parasites d'ambiance industrielles. Sa faible taille et son autono- mie lui permettent d'être intégré dans tout type d'organe de sécurité.The transmitter 4 of high frequency waves transmits coded information which cannot be disturbed or interfered with by the parasites of industrial environment. Its small size and its autonomy allow it to be integrated into any type of security organ.
Le récepteur 5 analyse les informations reçues, et si celles-ci sont cohérentes, l'alimentation de la machine ou de l'équipement industriel est établie. Si l'absence d'informations cohérentes devient continues, alors l'alimentation est interrompue. Le dispositif objet de l'invention peut être adapté à des appli¬ cations non industrielles. En particulier, il peut être utilisé pour contraindre un motocycliste à porter un casque pour pouvoir mettre sa machine en route, un contacteur inviolable coupant le circuit d'allumage lorsque cette condition n'est pas réalisée. Le positionnement des divers éléments constitutifs donnent à ce dispositif un maximum d'effets utiles qui n'avaient pas été. obtenus à ce jour par des dispositifs similaires. The receiver 5 analyzes the information received, and if it is consistent, the power supply to the machine or to the industrial equipment is established. If the absence of consistent information becomes continuous, then the power supply is interrupted. The device which is the subject of the invention can be adapted to non-industrial applications. In particular, it can be used to force a motorcyclist to wear a helmet in order to be able to start his machine, a tamper-resistant contactor cutting off the ignition circuit when this condition is not fulfilled. The positioning of the various constituent elements gives this device a maximum of useful effects that had not been. obtained to date by similar devices.
