Abstract

The device for controlling the operation of a dangerous electrical machine comprises a box (1) attached to a bracelet which is worn around the user's wrist. The box includes on its top surface a force sensor (3) covered by a visco-elastic material (2) which may be struck by the user to activate a signal. When the surface is struck (6), the sensor provides a signal which is processed and then converted into radio waves (7) which are transmitted. The radio waves are picked up by a receiver mounted in a fixed box (8). The receiver is associated with relay contacts which change state on receipt of the radio signal. These may be used to switch off the electrical machinery. The circuit also includes visible and audible warnings (12,13) indicating that the device has been triggered.

Description

L'invention présentée concerne un dispositif permettant rarrêt urgence de toute machine électrique pouvant présenter un danger imminent pour son utilisateur ou son entourage immédiat.The present invention relates to a device for emergency shutdown of any electrical machine which may present an imminent danger to its user or his immediate entourage.

Le système qui en fait, transmettra une information électnque, pourra être
utilisé pour signaler, et ou suppnmer tout état considéré comme dangereux.The system which actually transmits electrical information can be
used to report and / or suppress any condition considered dangerous.

Les systèmes traditionnels arrêt d'urgence sont placés sur les machines
dont ils dépendent : ce qui peut nécessiter un déplacement donc un délai traction. Traditional emergency stop systems are placed on the machines
on which they depend: which can require a displacement therefore a traction delay.

in'autre part, leur emplacement ne facilite pas toujours faction d'arrêt
d'urgence; il faut éventuellement se remémorer instantanément ou trouver le bouton darrêt:Yaction est alors une succession tractions réflexes.on the other hand, their location does not always facilitate stopping faction
emergency; it may be necessary to instantly remember or find the stop button: Yaction is then a succession of reflex pullups.

Le dispositif utilise le réflexe humain devant le danger, en optimisant le temps d'action et la qualité de cette action
Le temps entre la décision et la fin de raction doit être le plus court
possible, il est fonction dune distance . Pour le réduire, on placera le système sur rutilisateur (ou les utilisateurs) de la machine
La qualité de l'action impliquera un emplacement privilégié sur rutilisateur,
ainsi qu'une forme optimisée, ce qui permettra d'obtenir une efficacité
maximum du réflexe.The device uses the human reflex in the face of danger, optimizing the action time and the quality of this action
The time between the decision and the end of the reaction must be the shortest
possible, it is a function of distance. To reduce it, we will place the system on the user (or users) of the machine
The quality of the action will imply a privileged location on the user,
as well as an optimized shape, which will allow to obtain an efficiency
maximum reflex.

Une action par réflexe est d'autant plus précise et sûre qu'eile est effectuée par les parties du corps qui s'y prêtent le mieux ( mains, bras)
Le dispositif réunit les critères cités précédemment . Il est constitué de deux parties distinctes reliées entre elles par faisceaux hertziens.An action by reflex is all the more precise and sure that it is carried out by the parts of the body which lend themselves best to it (hands, arms)
The system meets the criteria mentioned above. It is made up of two distinct parts linked together by radio-relay systems.

La première se présente sous la forme d'un boitier muni d'un bracelet attaché au poignet et sur lequel est fixé un ensemble constitué dun capteur de force souple recouvert d'un matériau viscoélastique de forme hémisphérique étanche aux poussières, qui permettra la transmission et l'amortissement des percussions . On rappellera bracelet urgence. The first is in the form of a case fitted with a bracelet attached to the wrist and on which is fixed an assembly consisting of a flexible force sensor covered with a viscoelastic material of hemispherical shape, dustproof, which will allow transmission and amortization of percussion. We will remember emergency bracelet.

Un bouton encastré autonse rinitialisation après activation L'intérieur du boîtier comprend une pile, rélectronique de traitement du signal
issu du capteur et l'électronique des transmissions hertziennes( émetteurs H.F. A recessed button does not reset after activation The inside of the case includes a battery, electronic signal processing
from the sensor and electronics of radio transmissions (HF transmitters

véhiculant l'information jusqu'a la deuxième partie. conveying the information until the second part.

La deuxième partie représente un boîtier contenant l'ensemble des circuits de réceptions H.F. et dune électronique destinée à commander un relais à contacts secs, étanche aux poussières.The second part represents a box containing all of the HF reception circuits and electronics intended to control a dry contact relay, dustproof.

Selon des modes particuliers de réalisations.According to particular embodiments.

- La forme et l'emplacement de la première partie peuvent différer en ce qu'elle peut s'utiliser comme pendentif, placée au niveau de la poitnne. - The shape and location of the first part may differ in that it can be used as a pendant, placed at the level of the chest.

-- Cette première partie peut comporter un petit afficheur indiquant l'heure
dans l'hypothèse d'un matériau viscoélastique transparent.- This first part can include a small display showing the time
on the assumption of a transparent viscoelastic material.

- Le transport de rinformation électrique par voies hertziennes pourra
se faire à raide d' une ou plusieurs transmissions simultanées, utilisants
des fréquences différentes.- The transport of electrical information by radio channels may
be done with one or more simultaneous transmissions, using
different frequencies.

- La deuxième partie sera adaptée de par sa forme aux utiiisations, qu'elles
soient industrielles ou grand public: placée dans une armoire électnque
de commande, reliée au circuit de commande, ou à intercaler entre
le secteur et une petite machine.- The second part will be adapted by its form to the uses, whether
either industrial or general public: placed in an electrical cabinet
control, connected to the control circuit, or to be inserted between
the sector and a small machine.

En référence à ce dessin le dispositif comprend pour la première partie
un boîtier(1) (dimensions approximative d'une montre) relié à un bracelet(4)
permettant une fixation au poignet de l'utilisateur. Le boîtier(lj est enveloppé
sur sa partie supéneure par un capteur de force (3) souple recouvert d'un matériau viscoélastique (2) de forme hémisphérique utilisé pour transmettre
et amortir rénergie mécanique provenant de la percussion (6). Le signal
électrique généré en sortie du capteur (3) est traité par une électronique logée
dans le boîtier(l),qui va::
-- lui appliquer un filtrage passôbas afin de suppnmer toutes perturbations
--comparer sa valeur à un seuil correspondant à une percussion (6) d'amplitude
donnée.With reference to this drawing, the device includes for the first part
a case (1) (approximate dimensions of a watch) connected to a bracelet (4)
allowing attachment to the user's wrist. The case (lj is wrapped
on its upper part by a flexible force sensor (3) covered with a viscoelastic material (2) of hemispherical shape used to transmit
and dampen mechanical energy from percussion (6). The signal
electrical output from the sensor (3) is processed by housed electronics
in the box (l), which will:
- apply passôbas filtering to eliminate any disturbances
- compare its value to a threshold corresponding to a percussion (6) of amplitude
given.

- activer un circuit encodeur suivi d'une ou plusieurs émissions hertziennes (7)
simultanées de fréquences différentes, pendant une durée telle que, Zinformation
émise soit assurément prise en compte.- activate an encoder circuit followed by one or more radio transmissions (7)

commandera un relais à contacts secs (10), activant jarret de la machine par la
coupure de ses alimentations. The second part which is responsible for receiving radio transmissions (7),
consists of a box (8) in which one or more reception circuits corresponding to the different frequencies transmitted, will be charged through a
decoder to restore electronic information from percussion (6) and which
will control a dry contact relay (10), activating the machine's halt by the
power cut.

Le coffret (8) sera adapté à l'utilisation soit - intercalé entre la prise secteur et ia machine pour le domaine grand public - fixé à armoire électrique de commande des machines dites industnelles
et, relié au circuit électnque de sécurité par l'intermédiaire des contacts secs du relais (10).The box (8) will be suitable for use either - interposed between the mains socket and the machine for the consumer sector - fixed to the electrical cabinet for controlling so-called industrial machines
and, connected to the electrical safety circuit via the dry contacts of the relay (10).

L'alimentation électnque de la deuxième partie sera obtenue à partir du secteur. The power supply for the second part will be obtained from the mains.

L'utilisation du dispositif selon les options de réalisations peut se décnre comme suit:
Devant le danger immédiat que représente la machine, les réflexes de rutilisateur vont l'amener à appliquer une percussion (6) sur le dôme hémisphérique (2) soit
en utilisant son autre poignet ou, par mouvement brusque du bras porteur du bracelet (4) en direction d'un obstacle.The use of the device according to the implementation options can be described as follows:
Faced with the immediate danger represented by the machine, the user's reflexes will lead him to apply a percussion (6) on the hemispherical dome (2) either
using his other wrist or, by abrupt movement of the carrying arm of the bracelet (4) towards an obstacle.
