Definitions
- the present invention relates to the field of access doors to a transport vehicle.
- These access doors can first of all designate doors belonging to transport vehicles, in particular of the train, tramway, metro, trolleybus or even bus type. Within the meaning of the invention, these access doors also designate so-called landing doors, also called platform facades.
- the invention relates to a transport vehicle door which can comprise either a single leaf or several leaves, typically two leaves. Furthermore, these access doors can in particular be of the sliding type, or even sliding, or even oscillating.
- the present invention relates more specifically to such an access door which comprises means for diagnosing the correct operation of a mechanical member of the push-button type, which makes it possible to detect the presence of passengers in the vicinity of the door. It further relates to a method of implementing this access door, including a diagnostic phase of this detection member. The invention finally relates, on the one hand to a transport vehicle, and on the other hand to a platform facade, which are respectively equipped with at least one such access door.
- a transport vehicle access door comprises a frame, as well as an opening formed by at least one leaf.
- the latter is movable relative to the frame between a closed position, in which this leaf closes a bay provided in the frame, as well as an open position in which it frees access to this bay.
- This leaf can be set in motion, typically using an electric motor activated by means of a control board.
- This plate receives information from a detection device, which signals the presence of passengers wishing to open or, on the contrary, close the door.
- this detection member is made in the form of a push button.
- a passenger wishes to control the opening of the leaf, so as to enter or exit the vehicle, he presses this push button.
- the information is then transmitted to the control plate which transmits it to the motor, thus causing the movement of the leaf.
- a sensor is generally provided capable of detecting a presence, in particular that of a user's hand, in the vicinity of this sensor. If detected, this sensor then transmits the information to the control board, so as to move the leaf.
- This type of contactless detection device is, however, not very commonly used. Furthermore, it may be subject to breakdowns of electronic origin. Finally, these sensors can deliver erroneous information, in particular false detections, particularly in the event of fog or if they are subject to glare.
- WO 2021/185 908 a door that is equipped with both a mechanical sensing element as well as a contactless sensing element.
- the control board which equips this door, receives in service a first information representative of the activation state of the mechanical element, as well as a second information representative of the activation state of the contactless element .
- an objective of the present invention is to remedy, at least partially, the disadvantages of the prior art mentioned above.
- Another objective of the invention is to propose an access door to a transport vehicle which, while offering additional possibilities of detection with regard to the prior art, ensures a diagnosis of the detection member equipping this door .
- Another objective of the invention is to provide such an access door, which makes it possible to indicate to the operator possible risks of breakdowns likely to affect the detection unit, in the short or medium term.
- Another objective of the invention is to propose such an access door, the structure of which does not undergo significant modification compared to existing doors, in particular with regard to its control plate.
- the invention also relates to a transport vehicle, in particular of the train, tramway, metro, trolleybus or even bus type, this vehicle comprising at least one door such as above.
- the subject of the invention is a platform facade for a transport vehicle, in particular of the train, tramway, metro, bus or even trolleybus type, this platform facade comprising at least one door such as above.
- a detection member which is equipped with two types of detection elements. This is a first element of a mechanical nature, detecting physical support, as well as a second element of a contactless nature, capable of detecting a presence without however requiring physical contact. This redundancy makes it possible to improve the availability of the detection member according to the invention, since the breakdown possible of one of the detection elements can be supplemented by the proper functioning of the other of these elements.
- the invention provides, in addition to the combination of the above functions, an additional diagnostic functionality.
- it involves carrying out predictive maintenance which makes it possible to draw the operator's attention, either to an immediate malfunction of the contactless element, or to a potential breakdown of the mechanical element. .
- This diagnosis constitutes valuable information for the operator. Indeed, if the diagnosis in accordance with the invention is not carried out, the detection member can continue to be operational since its mechanical detection element is still functioning. However, this detection element is partially faulty and is therefore at the mercy of a breakdown of the mechanical element, which would render it completely inoperative and cause a complete stop of the vehicle. Consequently, it may be particularly advantageous for the operator to intervene immediately, so as to repair or replace the contactless element before the mechanical element in turn suffers a breakdown.
- FIG 1 illustrates, schematically and partially, a transport vehicle 300 which is for example a train, a tram, a metro, a bus or even a trolleybus.
- a transport vehicle 300 which is for example a train, a tram, a metro, a bus or even a trolleybus.
- this figure 1 we have shown only in a simplified manner, a section of the body 302 of this vehicle.
- This figure also illustrates an access door according to the invention, designated generally by the reference 1, which equips this transport vehicle 300.
- this door comprises a frame 10, arranged at the periphery of a bay 304 provided in the body of the vehicle.
- This door is further provided with two leaves 20 and 25 forming an opening, each movable between respective opening and closing positions of the bay 304.
- this door can be provided with a single leaf, or else of several leaves.
- this door is of the sliding type, it being understood that it can be of a different type, in particular sliding sliding.
- the aforementioned bay 304 delimits a free passage for users, in the opening position of each leaf.
- FIG. 1 also illustrates means, allowing the driving of each leaf relative to the frame, in a direction which corresponds to the rolling axis of the vehicle.
- These drive means firstly comprise a motor 310 of any suitable type, for example electric.
- This motor is controlled by a plate 6, via a control line 314.
- This motor cooperates with a drive member, for example of the endless screw type 316, which is integral in translation with the frame.
- a so-called driven member 320 and 325 integral with a respective leaf 20 and 25.
- Each driven member is for example produced in the form of a cylindrical body, the internal surface of which forms a nut intended to cooperate with the worm screw above.
- the different mechanical elements, listed above, are of the classic type so that they will not be described in more detail in what follows.
- a detection member which constitutes an essential element of the invention, which is provided on the exterior face 22 of the leaf 20 shown on the figure 1 . It must be understood that, as will be detailed below, another detection member generally equips the interior face 24 of this same leaf 20.
- the other leaf 25 is, conventionally, devoid of detection member, both on its interior and exterior face.
- the detection member 3 firstly comprises a housing 30, fixed to the leaf by any appropriate means.
- This box first supports a mechanical detection element, of the push-button type.
- This mechanical element which is classic, is represented schematically by being assigned the reference 32.
- the detection member 3 is further equipped with an additional detection element 34, also illustrated schematically, which is called “ contactless” or “touchless”.
- This contactless detection element 34 is adapted to detect the presence of the hand 36 of a user, visible on this figure 2 , inside a so-called detection zone 38. It can be of any appropriate type, in particular optical, capacitive or even thermal.
- This so-called “contactless” element 34 is typically a sensor operating on the known principle of “time of flight” (or “Time of Flight” in English). As shown in this figure 2 , this sensor is able to react to movements of a hand 36 which can be exercised in different directions, such as in particular a sweep of this hand.
- control board 6 firstly comprises a so-called control unit 60, which is adapted in a conventional manner to activate the control line 314, with a view to moving the door.
- this plate 6 is further equipped with a diagnostic unit 70, the structure of which will be detailed with reference to the Figure 4 .
- diagnostic unit 70 the structure of which will be detailed with reference to the Figure 4 .
- first line 4 which is dedicated only to the transfer of information concerning the mechanical detection element 32, extends only from the latter.
- second transfer line 5 which is dedicated only to the transfer of information relating to the contactless detection element 34, extends only from the latter.
- Each line 4 and 5, called main, is divided into two downstream lines called derived, mutually placed in parallel.
- line 4 is divided into a line 42 in communication with the control unit 60, as well as a line 41 in communication with the diagnostic unit 70.
- line 5 is divided into a line 52 in communication with the control unit 60, as well as a line 51 in communication with the diagnostic unit 70.
- the diagnostic unit 70 firstly comprises a main so-called analysis module 72, which is more particularly adapted to process the signals received from the transfer lines 4 and 5.
- This analysis module 72 is connected directly with lines 41 and 51 above, delivering the original information respectively mechanical and contactless.
- this analysis module 72 is connected, via a line 78, to a malfunction module 80.
- the latter is associated with a processor 82 which can activate, via a line 84, an alert 86, for example of visual type and/or hearing, which can be perceived by the vehicle operator.
- the analysis module 72 is connected, via a line 88, to a memory module 90.
- the information stored in this module 90 can be managed in several ways. Thus, we can first of all associate this module 90 with an additional processor 92 which can activate, via a line 94, an additional alert 96. We can also, as a complement or as an alternative, plan to interrogate this memory module , using all appropriate means such as a maintenance center. Such an interrogation, which can be implemented on site or remotely, will for example be carried out periodically.
- a first piece of information I said to be representative of the activation state of the mechanical detection element 32 is transferred between the detection member and the control board, as well as a second piece of information.
- information said to be representative of the activation state of the contactless detection element 34 is transferred between the detection member and the control board, as well as a second piece of information.
- information I and It corresponds to the activation state of a single detection element, respectively mechanical or contactless.
- each piece of information does not take into account the activation state of the other element, respectively contactless or mechanical.
- each piece of information I and II is carried by a respective electrical signal S1 and S2.
- the information I has two values which are called “active” and “inactive”. These values, assigned the references I(1) and I(0) in the figures, correspond respectively to peaks and troughs of the signal S1.
- the information Il similarly has two active and inactive values, assigned the references II(1) and II(0), corresponding respectively to peaks and troughs of the signal S2.
- control unit 60 is connected both with the so-called mechanical line 42 and with the so-called contactless line 52. As soon as at least one detection element 32 or 34 is activated , the or each corresponding electrical signal S1 or S2 goes to its peak value, and the respective information I or It goes to its active value. The control unit 60 then recognizes this situation, so that it initiates the opening of the door in a conventional manner, via the command line 314.
- the diagnostic unit 70 four different operational cases can be distinguished, three of which will be detailed with reference to the figures 5 to 7 .
- the first signal I called mechanical
- the second signal II called contactless
- the peak amplitudes of these electrical signals are identical: however, in order to better distinguish them, they have been shown slightly different in the figures.
- each electrical signal S1 and S2 presents its trough value, so that each information I and It retains its inactive value. This means that no action is exerted on the detection device by any user. This occurrence does not call for any particular alert vis-à-vis the operator of the transport vehicle.
- the second case corresponds to an activation of both the mechanical element 32 and the contactless element 34.
- this corresponds to a usual use of the detection member, in which the user activates the element mechanical by exerting pressure on the latter. To do this, this user first crosses the detection zone 38 of the contactless element, so that he also activates the latter.
- this situation is materialized by the passage of the electrical signals S1 and S2 to their peak values, so that the information I and II now have active values I(1) and II(1). The appearance of this type of signal indicates proper functioning of the detection unit, both at the non-contact and mechanical levels.
- the control board does not emit any alert to the operator.
- the third case corresponds, on the Figure 6 , at the appearance of a single peak at the level of the electrical signal S1 relating to the mechanical element, while the other electrical signal S2 remains at its trough value.
- the information I has an active value of I(1), while the information It has an inactive value of II(0).
- the analysis module identifies, by any appropriate comparison between the signals, of conventional type, an activation of the mechanical element as well as an absence of activation of the contactless element. It concludes that the contactless detection element is malfunctioning, which leads to sending a message to the malfunction module 80.
- the identification of this malfunction can be explained by the fact that, when the mechanical element is activated, the user necessarily passes his hand through the detection field of the element without contact. Consequently, the absence of activation of the contactless element, during activation of the mechanical element, implies that this contactless element is not functioning correctly.
- the above situation can be managed in several ways. We can first of all decide that the malfunction module 80 activates the alert 86 perceptible by the operator, from the first occurrence of this malfunction. We can also decide that this alert is not activated immediately, but only when a predetermined number of malfunctions of this type have occurred.
- the fourth case corresponds, on the Figure 7 , upon the appearance of a single peak at the level of the electrical signal S2 relating to the contactless element, while the other electrical signal S1 remains at its trough value. Under these conditions the information I has an inactive value of I(0), while the information It has an active value of II(1).
- the analysis module then identifies, by a comparison between the signals which is similar to that implemented in the third case above, an absence of activation of the mechanical element as well as activation of the element without contact.
- the analysis module cannot necessarily conclude that the mechanical detection element is malfunctioning.
- two alternative situations can be considered in the case of Figure 7 . It is first possible that the user wishes to activate the detection member, without coming into contact with the latter. In this first situation the user activates the contactless element without however activate the mechanical element, so that the inactive value of the information I is not synonymous with a possible mechanical failure. It is also possible that the user actually pressed the detection element, so as to open or close the leaf. In this second situation the user has therefore theoretically activated the mechanical element, so that the inactive value of the information I allows a priori to conclude that there is a malfunction of this mechanical element.
- the analysis module provides the memory module with the nature of the different activations of the detection elements, both mechanical and contactless. Assuming that the contactless element functions correctly, there are only two possibilities: on the one hand the activation of the contactless element accompanied by the activation of the mechanical element, i.e. the appearance of the values (1) and II(1) on the Figure 5 , on the other hand the activation of the contactless element without activation of the mechanical element, i.e. the appearance of the values I(0) and II(1) on the Figure 7 .
- the memory module can provide a graph, such as that of the figure 8 , illustrating the variation in the percentage of mechanical activation (PM).
- This percentage corresponds to the ratio between, on the one hand, the number of activations of the mechanical element and, on the other hand, the total number of activations of the detection member.
- an MP percentage of 100 means that the mechanical element is activated every time
- a value of 0 of the same percentage means that the mechanical element is never activated
- a value of 50 means that this mechanical element is activated every other time.
- the control board may include a processor capable of analyzing the variation curves of the PM percentage, so as to identify the type of situations in which we find our.
- a first possibility then consists of immediately providing the corresponding information to the operator, in particular via alarm 96. The operator is then able to carry out all appropriate operations, typically the repair or replacement of the mechanical detection element. .
- the first information III is identical to that I, so that the transfer line 104 is also dedicated to the unique transfer of information concerning the mechanical detection element 132. Just as above, this information is carried by a respective electrical signal S'1, similar to that S1.
- the second information IV is different from that II in that it corresponds to the activation state, either of the mechanical detection element or of the contactless element.
- This information IV which can be called “opto-mechanical” therefore has a so-called active value corresponding to the reference IV(1), if one and/or the other of these elements is activated.
- the so-called inactive value of this information i.e. the reference IV(0), corresponds to an absence of activation of both the mechanical element and the contactless element.
- the transfer line 105 is dedicated to the transfer of information relating to both the mechanical detection element 132 and the contactless detection element 134. Just like this Above, this information is carried by an electrical signal S'2, similar to that S2.
- line 104 is similar to that 4, in that it comprises two downstream branch lines 141 and 142.
- line 105 comprises, in addition to the two downstream branch lines 151 and 152, two upstream branch lines 153 and 154. The latter extend respectively from the mechanical detection element 132 and from the contactless detection element 134.
- control board 106 is identical to that of the first variant, in particular in with regard to the structure of the control unit 160 and the diagnostic unit 170.
- the control unit 160 recognizes this situation, so that it initiates the opening of the door.
- each of the electrical signals S' 1 and S'2 presents a hollow value. Consequently, each information III and IV has an inactive value, which does not require any particular action.
- the electrical signals S'1 and S'2 go to a peak value. Under these conditions, each piece of information has an active value, materialized respectively by III(1) and IV(1) on the Figure 11 . Furthermore, advantageously, the electrical signal S'2 reaches its peak value before the electrical signal S'1, so as to define a preliminary peak C'2, appearing before the peak of the other signal S'1. As in the first variant, the Figure 11 indicates good functioning of the detection element, both at the non-contact and mechanical levels.
- the signal S'1 has the same profile as on the Figure 11 .
- the signal S'2 is different from that of the Figure 11 , in that it lacks a preliminary C'2 crest. Consequently the diagnostic unit, which identifies the absence of this preliminary peak, concludes that there is no activation of the contactless element. In fact, the passage from information IV to its active value IV(1) is initiated by the sole activation of the mechanical element. As in the first variant above, the diagnostic unit immediately concludes that there is a malfunction of the contactless element. Analogous to the first variant, this situation can be the subject of different alerts to the operator.
- the signal S'2 has the same profile as on the Figure 11 .
- the signal S1 remains at its trough value, corresponding to an inactive value III(0) of the information III.
- the diagnostic unit identifies that the mechanical element has not been activated, without however concluding that there is a malfunction of the this one. The management of this situation can be implemented in the same way as in the first variant, with reference to the figure 8 .
- the detection elements conforming to this second variant of the invention, have specific advantages, in particular in that they can be easily integrated into an existing transport vehicle. In other words, they allow a convenient “upgrade” of this transport vehicle. Thus it is possible to replace a purely mechanical type detection member with an all-mechanical detection member, in accordance with the invention, by taking advantage of the transfer line 105.
- THE figures 14 and 15 illustrate a third alternative embodiment. On these figures 14 and 15 the constituent elements, which are similar to those of the first alternative embodiment, are assigned the same reference numbers increased by the number 200.
- This third variant differs from the first two variants above, in particular in that a single transfer line 204 is provided.
- this line 204 firstly comprises two upstream branch lines 243 and 244, which are extend respectively from the mechanical detection element 232 and from the contactless detection element 234.
- this line comprises two downstream branch lines 242 and 241, which connect respectively to the control unit 260 and to the diagnostic unit 270.
- the control board 206 is identical to that of the first two variants, in particular with regard to the structure of the control unit 260 and the diagnostic unit 270.
- each information V and VI corresponds to the activation state of a single detection element, respectively mechanical 232 or contactless 234, but does not take into account the activation state of the other element.
- the single line 204 conveys a single electrical signal, denoted S", from the detection member 203 to the control board 206.
- S a single electrical signal
- this unique electrical signal S" carries the two information V and VI.
- the diagnostic unit 270 cannot carry out a comparison between the signals, so as to distinguish the information which indicates mechanical activation compared to that indicating contactless activation.
- this identification is carried out thanks to the very nature of the unique electrical signal S".
- this signal is advantageously affected by means of different electrical signatures, one of which corresponds to the information V of mechanical type and the other of which corresponds to the contactless type VI information.
- electrical signatures which are known per se, can be of any appropriate type. Note that this definition of “different signatures” includes the possibility that the 'one of the activations is not assigned by means of a particular signature.
- a first electrical signature is materialized by a first pattern M1 of the electrical signal S", corresponding to a drop in the signal immediately followed by a rise.
- a second electrical signature is materialized by a second pattern M2 of this signal, corresponding to a repetition of the first pattern, namely the succession of a first fall, a first rise, a second fall and finally a second rise.
- the order of these signatures can be reversed.
- the electrical signal S" includes the two target patterns M1 and M2, which means that each piece of information has its active value V(1) and VI(1). We therefore conclude that the detection unit is functioning properly, also both mechanically and without contact.
- the electrical signal S" only includes the target pattern M1, but not that M2. This means that only the mechanical information V has its active value V(1), but on the other hand that the contactless information VI has its inactive value VI(0). Consequently, as above, the diagnostic unit 270 concludes that the contactless element is malfunctioning. Analogously to the first variants, this situation can be the subject of different alerts regarding towards the operator.
- the electrical signal S" only includes the target pattern M2, but not that M1.
- This third variant has specific advantages, particularly in economic terms. In fact, it makes it possible to simplify wiring and reduce the overall number of wiring, so that the associated costs are lower. Furthermore, the assembly of the constituent parts of this third variant is faster, at the level of the leaf manufacturing lines.
- the detection member 3,103,203 in accordance with the invention, equipping the exterior face 22 of the leaf 20. It is also possible for another detection member, also in accordance with the invention, to be provided on the interior face 24 of this same leaf. This interior detection member is then associated with the same mechanical elements as the exterior detection member 3,103,203. In particular the different transfer lines, both on the interior side and on the exterior side, are connected to the control board 6. In service it is necessary to ensure that, in all cases, this board is capable of clearly distinguishing the diagnosis issued. against the interior detection element, compared to that emitted against the exterior detection element.
- a detection element according to the invention has been described, on a transport vehicle door.
- the invention also finds its application to landing doors, also called platform facades, which are equipped with at least one such detection element.

Description
La présente invention concerne le domaine des portes d'accès à un véhicule de transport. Ces portes d'accès peuvent tout d'abord désigner des portes appartenant à des véhicules de transport, notamment de type train, tramway, métro, trolleybus ou encore bus. Au sens de l'invention, ces portes d'accès désignent également des portes dites palières, encore dénommées façades de quai. L'invention concerne une porte de véhicule de transport qui peut comporter, soit un unique vantail, soit plusieurs vantaux, typiquement deux vantaux. Par ailleurs, ces portes d'accès peuvent être notamment de type coulissant, ou encore louvoyant coulissant, voire oscillant.The present invention relates to the field of access doors to a transport vehicle. These access doors can first of all designate doors belonging to transport vehicles, in particular of the train, tramway, metro, trolleybus or even bus type. Within the meaning of the invention, these access doors also designate so-called landing doors, also called platform facades. The invention relates to a transport vehicle door which can comprise either a single leaf or several leaves, typically two leaves. Furthermore, these access doors can in particular be of the sliding type, or even sliding, or even oscillating.
La présente invention concerne plus spécifiquement une telle porte d'accès qui comprend des moyens pour diagnostiquer le bon fonctionnement d'un organe mécanique du type bouton-poussoir, qui permet de détecter la présence de passagers au voisinage de la porte. Elle concerne en outre un procédé de mise en oeuvre de cette porte d'accès, incluant une phase de diagnostic de cet organe de détection. L'invention concerne enfin, d'une part un véhicule de transport, d'autre part une façade de quai, qui sont respectivement équipés d'au moins une telle porte d'accès.The present invention relates more specifically to such an access door which comprises means for diagnosing the correct operation of a mechanical member of the push-button type, which makes it possible to detect the presence of passengers in the vicinity of the door. It further relates to a method of implementing this access door, including a diagnostic phase of this detection member. The invention finally relates, on the one hand to a transport vehicle, and on the other hand to a platform facade, which are respectively equipped with at least one such access door.
De manière classique une porte d'accès à véhicule de transport comporte un dormant, ainsi qu'un ouvrant formé d'au moins un vantail. Ce dernier est mobile par rapport au dormant entre une position de fermeture, dans laquelle ce vantail obture une baie ménagée dans le dormant, ainsi qu'une position d'ouverture dans laquelle il libère l'accès à cette baie. Ce vantail est susceptible d'être mis en mouvement, typiquement grâce à un moteur électrique activé au moyen d'une platine de commande.Conventionally, a transport vehicle access door comprises a frame, as well as an opening formed by at least one leaf. The latter is movable relative to the frame between a closed position, in which this leaf closes a bay provided in the frame, as well as an open position in which it frees access to this bay. This leaf can be set in motion, typically using an electric motor activated by means of a control board.
Cette platine reçoit des informations, provenant d'un organe de détection, lequel signale la présence de passagers désirant ouvrir ou au contraire fermer la porte. De manière classique, cet organe de détection est réalisé sous forme d'un bouton poussoir. Lorsqu'un passager désire commander l'ouverture du vantail, de façon à pénétrer dans le véhicule ou bien à en sortir, il appuie sur ce bouton poussoir. L'information est alors transmise à la platine de commande qui la répercute au niveau du moteur, entraînant ainsi le déplacement du vantail.This plate receives information from a detection device, which signals the presence of passengers wishing to open or, on the contrary, close the door. Conventionally, this detection member is made in the form of a push button. When a passenger wishes to control the opening of the leaf, so as to enter or exit the vehicle, he presses this push button. The information is then transmitted to the control plate which transmits it to the motor, thus causing the movement of the leaf.
Cette solution, de type purement mécanique, présente cependant certains inconvénients. En effet, un tel bouton poussoir peut être sujet à des défaillances électroniques. Par ailleurs, son bon fonctionnement peut être altéré par la présence d'eau. La nécessité d'un appui mécanique peut en outre se révéler peu commode, pour des voyageurs chargés d'objets encombrants, ou encore pour des personnes à mobilité réduite. Enfin cette première solution n'est pas satisfaisante sur le plan hygiénique puisque ce bouton poussoir se trouve régulièrement en contact avec les mains de nombreux utilisateurs, ce qui est vecteur de transmission de virus ou bactéries.This purely mechanical solution, however, has certain drawbacks. Indeed, such a push button can be subject to electronic failures. Furthermore, its proper functioning may be impaired by the presence of water. The need for mechanical support may also prove to be inconvenient for travelers loaded with bulky objects, or even for people with reduced mobility. Finally, this first solution is not satisfactory from a hygienic point of view since this push button is regularly in contact with the hands of many users, which is a vector for the transmission of viruses or bacteria.
Afin de remédier à ces différents inconvénients, on a proposé de faire appel à des organes de détection de type « sans contact », qui peuvent être activés sans qu'il y ait un appui de la part de l'utilisateur. Sur le plan structurel, il est en général prévu un capteur apte à détecter une présence, notamment celle de la main d'un utilisateur, au voisinage de ce capteur. En cas de détection, ce capteur transmet alors l'information à la platine de commande, de manière à déplacer le vantail. Ce type d'organes de détection sans contact n'est cependant pas d'une utilisation très commune. Par ailleurs, il peut faire l'objet de pannes d'origine électronique. Enfin ces capteurs peuvent délivrer des informations erronées, en particulier de fausses détections, notamment en cas de brouillard ou bien s'ils sont soumis à un éblouissement.In order to remedy these various drawbacks, it has been proposed to use “contactless” type detection devices, which can be activated without there being any support from the user. Structurally, a sensor is generally provided capable of detecting a presence, in particular that of a user's hand, in the vicinity of this sensor. If detected, this sensor then transmits the information to the control board, so as to move the leaf. This type of contactless detection device is, however, not very commonly used. Furthermore, it may be subject to breakdowns of electronic origin. Finally, these sensors can deliver erroneous information, in particular false detections, particularly in the event of fog or if they are subject to glare.
On connaît par ailleurs, de
On conçoit que le fonctionnement correct des organes de détection est essentiel à la bonne marche d'un véhicule de transport et, de façon générale, de l'ensemble du réseau. En effet, un éventuel dysfonctionnement entraîne nécessairement une mise à l'arrêt provisoire du véhicule de transport. Il s'ensuit un retard intempestif, ainsi qu'une gêne susceptible de se répercuter à l'ensemble du trafic.We understand that the correct operation of the detection elements is essential to the smooth running of a transport vehicle and, in general, of the entire network. Indeed, a possible malfunction necessarily results in a temporary shutdown of the transport vehicle. This results in an untimely delay, as well as inconvenience likely to have repercussions on all traffic.
Compte tenu de ce qui précède, un objectif de la présente invention est de remédier, au moins partiellement, aux inconvénients de l'art antérieur évoqués ci-dessus.Taking into account the above, an objective of the present invention is to remedy, at least partially, the disadvantages of the prior art mentioned above.
Un autre objectif de l'invention est de proposer une porte d'accès à un véhicule de transport qui, tout en proposant des possibilités supplémentaires de détection en regard de l'art antérieur, assure un diagnostic de l'organe de détection équipant cette porte.Another objective of the invention is to propose an access door to a transport vehicle which, while offering additional possibilities of detection with regard to the prior art, ensures a diagnosis of the detection member equipping this door .
Un autre objectif de l'invention est de proposer une telle porte d'accès, qui permet d'indiquer à l'exploitant d'éventuels risques de pannes susceptibles d'affecter l'organe de détection, à court ou moyen terme.Another objective of the invention is to provide such an access door, which makes it possible to indicate to the operator possible risks of breakdowns likely to affect the detection unit, in the short or medium term.
Un autre objectif de l'invention est de proposer une telle porte d'accès, dont la structure ne subit pas de modification significative par rapport aux portes existantes, en particulier en ce qui concerne sa platine de commande.Another objective of the invention is to propose such an access door, the structure of which does not undergo significant modification compared to existing doors, in particular with regard to its control plate.

Ces caractéristiques additionnelles peuvent être mises en oeuvre avec le deuxième objet principal ci-dessus, individuellement ou en combinaisons quelconques, techniquement compatibles.These additional characteristics can be implemented with the second main object above, individually or in any technically compatible combinations.
L'invention a également pour objet un véhicule de transport notamment de type train, tramway, métro, trolleybus ou encore bus, ce véhicule comportant au moins une porte telle que ci-dessus.The invention also relates to a transport vehicle, in particular of the train, tramway, metro, trolleybus or even bus type, this vehicle comprising at least one door such as above.
L'invention a enfin pour objet une façade de quai pour véhicule de transport, notamment du type train, tramway, métro, bus ou encore trolleybus, cette façade de quai comportant au moins une porte telle que ci-dessus.Finally, the subject of the invention is a platform facade for a transport vehicle, in particular of the train, tramway, metro, bus or even trolleybus type, this platform facade comprising at least one door such as above.
Conformément à l'invention, on prévoit un organe de détection qui est équipé de deux types d'éléments de détection. Il s'agit d'un premier élément de nature mécanique, détectant un appui physique, ainsi qu'un second élément de nature sans contact, apte à détecter une présence sans cependant nécessiter un contact physique. Cette redondance permet d'améliorer la disponibilité de l'organe de détection selon l'invention, puisque la panne éventuelle d'un des éléments de détection peut être suppléée par le bon fonctionnement de l'autre de ces éléments.According to the invention, a detection member is provided which is equipped with two types of detection elements. This is a first element of a mechanical nature, detecting physical support, as well as a second element of a contactless nature, capable of detecting a presence without however requiring physical contact. This redundancy makes it possible to improve the availability of the detection member according to the invention, since the breakdown possible of one of the detection elements can be supplemented by the proper functioning of the other of these elements.
Au surplus l'invention prévoit, outre l'association des fonctions ci-dessus, une fonctionnalité supplémentaire de diagnostic. En d'autres termes il s'agit d'opérer une maintenance prédictive qui permet d'attirer l'attention de l'exploitant, soit sur un dysfonctionnement immédiat de l'élément sans contact, soit sur une panne potentielle de l'élément mécanique.Furthermore, the invention provides, in addition to the combination of the above functions, an additional diagnostic functionality. In other words, it involves carrying out predictive maintenance which makes it possible to draw the operator's attention, either to an immediate malfunction of the contactless element, or to a potential breakdown of the mechanical element. .
On conçoit tout d'abord que, si l'utilisateur appuie sur l'élément mécanique de détection, il active également en théorie l'élément de détection sans contact. En effet le trajet de la main de l'utilisateur, venant en contact avec l'élément mécanique, traverse nécessairement la zone de détection de l'élément sans contact. Par conséquent, si on constate uniquement une activation de l'élément mécanique, mais en revanche pas celle de l'élément sans contact, on peut diagnostiquer immédiatement un dysfonctionnement de cet élément sans contact.First of all, we understand that, if the user presses on the mechanical detection element, he also theoretically activates the contactless detection element. In fact, the path of the user's hand, coming into contact with the mechanical element, necessarily crosses the detection zone of the contactless element. Consequently, if we only notice activation of the mechanical element, but not that of the contactless element, we can immediately diagnose a malfunction of this contactless element.
Ce diagnostic constitue une information précieuse, pour l'exploitant. En effet, si l'on ne réalise pas le diagnostic conforme à l'invention, l'organe de détection peut continuer à être opérationnel puisque son élément de détection mécanique fonctionne encore. Néanmoins, cet organe de détection est partiellement défaillant et se trouve donc à la merci d'une panne de l'élément mécanique, qui le rendrait totalement inopérant et entraînerait un arrêt complet du véhicule. Par conséquent, il peut être tout particulièrement avantageux pour l'exploitant d'intervenir de façon immédiate, de manière à réparer ou remplacer l'élément sans contact avant que l'élément mécanique ne subisse à son tour une panne.This diagnosis constitutes valuable information for the operator. Indeed, if the diagnosis in accordance with the invention is not carried out, the detection member can continue to be operational since its mechanical detection element is still functioning. However, this detection element is partially faulty and is therefore at the mercy of a breakdown of the mechanical element, which would render it completely inoperative and cause a complete stop of the vehicle. Consequently, it may be particularly advantageous for the operator to intervene immediately, so as to repair or replace the contactless element before the mechanical element in turn suffers a breakdown.
À l'inverse, dans le cas où on constate une activation de l'élément sans contact mais une absence d'activation de l'élément mécanique, on ne peut pas conclure de façon immédiate un dysfonctionnement de cet élément mécanique. En effet il est possible que l'utilisateur actionne l'élément sans contact sans cependant entrer en contact avec l'élément mécanique, de sorte que l'absence d'activation de ce dernier est tout à fait normale. Comme on le verra plus en détail dans la description qui va suivre, différents modes de diagnostic peuvent alors être envisagés.Conversely, in the case where we observe activation of the contactless element but an absence of activation of the mechanical element, we cannot immediately conclude a malfunction of this mechanical element. Indeed it is possible for the user to activate the contactless element without however coming into contact with the mechanical element, so that the absence of activation of the latter is completely normal. As will be seen in more detail in the description which follows, different diagnostic methods can then be considered.

De façon connue en soi cette porte comprend un dormant 10, disposé à la périphérie d'une baie 304 ménagée dans la caisse du véhicule. Cette porte est en outre pourvue de deux vantaux 20 et 25 formant ouvrant, chacun mobile entre des positions respectives d'ouverture et de fermeture de la baie 304. À titre de variante, cette porte peut être munie d'un unique vantail, ou bien de plusieurs vantaux. Dans l'exemple illustré cette porte est de type coulissant, étant entendu qu'elle peut être d'un type différent, notamment louvoyante coulissante. De manière classique la baie précitée 304 délimite un libre passage pour les usagers, dans la position d'ouverture de chaque vantail.In a manner known per se, this door comprises a

On va maintenant décrire plus en détail les moyens de détection, conformes à l'invention, qui équipent la porte 1 ci-dessus. Sur la
Comme le montre notamment la
Cet élément de détection sans contact 34 est adapté pour détecter la présence de la main 36 d'un utilisateur, visible sur cette
L'élément sans contact 34 est relié à la platine de commande 6, par des lignes de transfert 4 et 5, qui sont représentées de manière schématique sur la
De façon plus précise la première ligne 4, qui est dédiée seulement au transfert d'informations concernant l'élément de détection mécanique 32, s'étend uniquement à partir de ce dernier. Par ailleurs la seconde ligne de transfert 5, qui est dédiée seulement au transfert d'informations relatives à l'élément de détection sans contact 34, s'étend uniquement à partir de ce dernier. Chaque ligne 4 et 5, dite principale, est divisée en deux lignes aval dites dérivées, placées mutuellement en parallèle. Ainsi la ligne 4 se divise en une ligne 42 en communication avec l'unité de commande 60, ainsi qu'une ligne 41 en communication avec l'unité de diagnostic 70. De façon analogue la ligne 5 se divise en une ligne 52 en communication avec l'unité de commande 60, ainsi qu'une ligne 51 en communication avec l'unité de diagnostic 70.More precisely, the
En référence désormais à la
Enfin le module d'analyse 72 est relié, via une ligne 88, à un module de mémoire 90. Les informations stockées dans ce module 90 peuvent être gérées de plusieurs façons. Ainsi on peut tout d'abord associer ce module 90 à un processeur supplémentaire 92 qui peut activer, via une ligne 94, une alerte supplémentaire 96. On peut également, à titre complémentaire ou à titre alternatif, prévoir d'interroger ce module de mémoire, grâce à tous moyens appropriés comme un centre de maintenance. Une telle interrogation, qui peut être mise en oeuvre sur place ou à distance, sera par exemple réalisée de façon périodique.Finally, the
Dans toute la généralité de l'invention on transfère, entre l'organe de détection et la platine de commande, une première information I dite représentative de l'état d'activation de l'élément de détection mécanique 32, ainsi qu'une seconde information dite représentative de l'état d'activation de l'élément de détection sans contact 34. Dans la présente variante, illustrée en référence aux
Dans cette variante, chaque information I et Il est portée par un signal électrique respectif S1 et S2. Selon que l'élément mécanique 32 est activé ou non, l'information I possède deux valeurs qui sont dénommées « active » et « inactive ». Ces valeurs, affectées des références I(1) et I(0) sur les figures, correspondent respectivement à des crêtes et des creux du signal S1. Selon que l'élément sans contact 34 est activé ou non, l'information Il possède de façon analogue deux valeurs active et inactive, affectées des références II(1) et II(0), correspondant respectivement à des crêtes et des creux du signal S2.In this variant, each piece of information I and II is carried by a respective electrical signal S1 and S2. Depending on whether the
Comme on l'a vu ci-dessus, l'unité de commande 60 est reliée à la fois avec la ligne dite mécanique 42 et avec la ligne dite sans contact 52. Dès qu'au moins un élément de détection 32 ou 34 est activé, le ou chaque signal électrique correspondant S1 ou S2 passe à sa valeur de crête, et l'information respective I ou Il passe à sa valeur active. L'unité de commande 60 reconnaît alors cette situation, de sorte qu'elle initie l'ouverture de la porte de manière classique, via la ligne de commande 314.As seen above, the
En ce qui concerne l'unité de diagnostic 70, on peut distinguer quatre cas opérationnels différents, dont trois vont être détaillés en référence aux
Le premier de ces cas, qui n'est pas représenté sur les figures, correspond à une absence d'activation, aussi bien de l'élément mécanique 32 que de l'élément sans contact 34. Dans ce cas, chaque signal électrique S1 et S2 présente sa valeur de creux, de sorte que chaque information I et Il conserve sa valeur inactive. Cela signifie qu'aucune action n'est exercée sur l'organe de détection, par un quelconque utilisateur. Cette occurrence n'appelle aucune alerte particulière, vis-à-vis de l'exploitant du véhicule de transport.The first of these cases, which is not shown in the figures, corresponds to an absence of activation, both of the
Le second cas correspond à une activation, à la fois de l'élément mécanique 32 et de l'élément sans contact 34. En pratique cela correspond à une utilisation habituelle de l'organe de détection, dans laquelle l'utilisateur active l'élément mécanique en exerçant un appui sur ce dernier. Pour ce faire, cet utilisateur traverse au préalable la zone de détection 38 de l'élément sans contact, de sorte qu'il active également ce dernier. En référence à la
Le troisième cas correspond, sur la
Comme cela a été expliqué ci-dessus, l'identification de ce dysfonctionnement peut être expliquée par le fait que, lorsque que l'élément mécanique est activé, l'utilisateur fait nécessairement passer sa main dans le champ de détection de l'élément sans contact. Par conséquent l'absence d'activation de l'élément sans contact, lors d'une activation de l'élément mécanique, implique que cet élément sans contact ne fonctionne pas correctement.As explained above, the identification of this malfunction can be explained by the fact that, when the mechanical element is activated, the user necessarily passes his hand through the detection field of the element without contact. Consequently, the absence of activation of the contactless element, during activation of the mechanical element, implies that this contactless element is not functioning correctly.
La situation ci-dessus, correspondant aux signaux de la
Le quatrième cas correspond, sur la
Contrairement au troisième cas ci-dessus, le module d'analyse ne peut pas nécessairement conclure au dysfonctionnement de l'élément de détection mécanique. En effet, deux situations alternatives peuvent être envisagées dans le cas de la
Conformément à une variante avantageuse de l'invention, les situations conformes à ce quatrième cas peuvent être gérées en utilisant le module de mémoire. Dans cet esprit le module d'analyse fournit au module de mémoire la nature des différentes activations des éléments de détection, à la fois mécanique et sans contact. En supposant que l'élément sans contact fonctionne correctement, il existe uniquement deux possibilités : d'une part l'activation de l'élément sans contact accompagnée de l'activation de l'élément mécanique, soit l'apparition des valeurs (1) et II(1) sur la
À partir de la compilation de ces différentes informations, le module de mémoire peut fournir un graphe, tel que celui de la
Cela étant précisé, la
Sur cette même
Enfin la courbe C3, en traits pleins sur la
À partir de ces différentes situations de la
La platine de commande peut comporter un processeur apte à analyser les courbes de variations du pourcentage PM, de manière à identifier le type de situations dans lequel on se trouve. On peut par exemple prévoir que le processeur peut calculer à chaque instant une valeur instantanée C' de la pente de la courbe PM, laquelle correspond à la dérivée de la courbe PM = f(t). Si le processeur identifie que cette valeur instantanée C' est supérieure à une valeur seuil prédéterminée C'S, il conclut à une baisse particulièrement rapide de la valeur de PM, représentative d'un dysfonctionnement. Une première possibilité consiste alors à fournir immédiatement le renseignement correspondant à l'exploitant, notamment via l'alarme 96. L'exploitant est alors à même de procéder à toutes opérations appropriées, typiquement la réparation ou le remplacement de l'élément de détection mécanique. À titre d'alternative, on peut prévoir de stocker ce renseignement dans le module de mémoire qui, comme on l'a vu ci-dessus, peut être consulté périodiquement par l'exploitant.The control board may include a processor capable of analyzing the variation curves of the PM percentage, so as to identify the type of situations in which we find ourselves. We can for example predict that the processor can calculate at each instant an instantaneous value C' of the slope of the PM curve, which corresponds to the derivative of the PM curve = f(t). If the processor identifies that this instantaneous value C' is greater than a predetermined threshold value C'S, it concludes that there is a particularly rapid drop in the PM value, representative of a malfunction. A first possibility then consists of immediately providing the corresponding information to the operator, in particular via
En revanche, on peut prévoir que le processeur peut détecter que la courbe PM = f(t) passe au-dessous d'une valeur seuil PS, illustrée sur la
Les
Dans cette seconde variante, la première information III est identique à celle I, de sorte que la ligne de transfert 104 est également dédiée au transfert unique d'informations concernant l'élément de détection mécanique 132. Tout comme ci-dessus, cette information est portée par un signal électrique S'1 respectif, analogue à celui S1.In this second variant, the first information III is identical to that I, so that the
En revanche la seconde information IV est différente de celle II en ce qu'elle correspond à l'état d'activation, soit de l'élément de détection mécanique, soit de l'élément sans contact. Cette information IV, qui peut être dénommée « opto mécanique » possède donc une valeur dite active correspondant à la référence IV(1), si l'un et/ou l'autre de ces éléments est activé. Par ailleurs la valeur dite inactive de cette information, soit la référence IV(0), correspond à une absence d'activation à la fois de l'élément mécanique et de l'élément sans contact. En d'autres termes, contrairement à la première variante, la ligne de transfert 105 est dédiée au transfert d'informations relatives à la fois à l'élément de détection mécanique 132 et à l'élément de détection sans contact 134. Tout comme ci-dessus, cette information est portée par un signal électrique S'2, analogue à celui S2.On the other hand, the second information IV is different from that II in that it corresponds to the activation state, either of the mechanical detection element or of the contactless element. This information IV, which can be called “opto-mechanical” therefore has a so-called active value corresponding to the reference IV(1), if one and/or the other of these elements is activated. Furthermore, the so-called inactive value of this information, i.e. the reference IV(0), corresponds to an absence of activation of both the mechanical element and the contactless element. In other words, unlike the first variant, the
Sur le plan structurel la ligne 104 est analogue à celle 4, en ce qu'elle comporte deux lignes dérivées aval 141 et 142. Par ailleurs la ligne 105 comprend, outre les deux lignes dérivées aval 151 et 152, deux lignes dérivées amont 153 et 154. Ces dernières s'étendent respectivement, à partir de l'élément de détection mécanique 132 et à partir de l'élément de détection sans contact 134. Enfin la platine de commande 106 est identique à celle de la première variante, en particulier en ce qui concerne la structure de l'unité de commande 160 et de l'unité de diagnostic 170.Structurally,
Tout comme dans la première variante, dès qu'au moins un élément de détection 132 et 134 est activé, le ou chaque signal électrique correspondant S'1 ou S'2 passe à sa valeur de crête. Par conséquent, la ou chaque information correspondante III ou IV passe à sa valeur active. L'unité de commande 160 reconnaît alors cette situation, de sorte qu'elle initie l'ouverture de la porte.Just as in the first variant, as soon as at least one
Différents cas opérationnels peuvent être distingués, en ce qui concerne l'unité de diagnostic 170. Tout d'abord, comme dans la première variante, en l'absence d'activation des éléments de détection 132 et 134, chacun des signaux électriques S'1 et S'2 présente une valeur de creux. Par conséquent, chaque information III et IV possède une valeur inactive, ce qui n'appelle pas d'action particulière.Different operational cases can be distinguished, with regard to the

Les organes de détection, conformes à cette seconde variante de l'invention, présentent des avantages spécifiques, notamment en ce qu'ils peuvent être intégrés aisément sur un véhicule de transport existant. En d'autres termes, ils permettent un « upgrade » commode de ce véhicule de transport. Ainsi il est possible de remplacer un organe de détection de type purement mécanique par un organe de détection tout mécanique, conforme à l'invention, en tirant parti de la ligne de transfert 105.The detection elements, conforming to this second variant of the invention, have specific advantages, in particular in that they can be easily integrated into an existing transport vehicle. In other words, they allow a convenient “upgrade” of this transport vehicle. Thus it is possible to replace a purely mechanical type detection member with an all-mechanical detection member, in accordance with the invention, by taking advantage of the

Cette troisième variante diffère des deux premières variantes ci-dessus, notamment en ce qu'il est prévu une unique ligne de transfert 204. Sur le plan structurel cette ligne 204 comprend tout d'abord deux lignes dérivées amont 243 et 244, qui s'étendent respectivement à partir de l'élément de détection mécanique 232 et à partir de l'élément de détection sans contact 234. Par ailleurs cette ligne comporte deux lignes dérivées aval 242 et 241, qui se connectent respectivement à l'unité de commande 260 et à l'unité de diagnostic 270. Enfin la platine de commande 206 est identique à celle des deux premières variantes, en particulier en ce qui concerne la structure de l'unité de commande 260 et de l'unité de diagnostic 270.This third variant differs from the first two variants above, in particular in that a
Dans cette troisième variante, comme pour la première variante ci-dessus, chaque information V et VI correspond à l'état d'activation d'un unique élément de détection, respectivement mécanique 232 ou sans contact 234, mais ne prend pas en compte l'état d'activation de l'autre élément. En revanche, contrairement aux premières variantes, la ligne unique 204 véhicule un unique signal électrique, noté S", depuis l'organe de détection 203 vers la platine de commande 206. Par opposition aux variantes ci-dessus, dans lesquelles chaque information est portée par un signal électrique respectif, ce signal électrique unique S" porte les deux informations V et VI.In this third variant, as for the first variant above, each information V and VI corresponds to the activation state of a single detection element, respectively mechanical 232 or contactless 234, but does not take into account the activation state of the other element. On the other hand, unlike the first variants, the
Contrairement aux deux premières variantes, l'unité de diagnostic 270 ne peut pas mettre en oeuvre de comparaison entre les signaux, de manière à distinguer l'information qui indique l'activation mécanique par rapport à celle indiquant l'activation sans contact. Dans ces conditions, dans cette troisième variante, cette identification est réalisée grâce à la nature même du signal électrique unique S". En pratique, on affecte avantageusement ce signal au moyen de signatures électriques différentes, dont l'une correspond à l'information V de type mécanique et dont l'autre correspond à l'information VI de type sans contact. Ces signatures électriques, qui sont connues en soi, peuvent être de tout type approprié. On notera que cette définition de « signatures différentes » inclut la possibilité que l'une des activations n'est pas affectée au moyen d'une signature particulière.Unlike the first two variants, the

Cette troisième variante présente des avantages spécifiques, notamment en termes économiques. En effet elle permet de simplifier les câblages et de réduire le nombre global de ces derniers, de sorte que les coûts associés sont plus faibles. Par ailleurs, l'assemblage des pièces constitutives de cette troisième variante est plus rapide, au niveau des chaînes de fabrication des vantaux.This third variant has specific advantages, particularly in economic terms. In fact, it makes it possible to simplify wiring and reduce the overall number of wiring, so that the associated costs are lower. Furthermore, the assembly of the constituent parts of this third variant is faster, at the level of the leaf manufacturing lines.
L'invention n'est pas limitée aux exemples décrits et représentés.The invention is not limited to the examples described and represented.
Dans ce qui précède on a uniquement décrit l'organe de détection 3,103,203, conforme à l'invention, équipant la face extérieure 22 du vantail 20. On peut également prévoir qu'un autre organe de détection, également conforme à l'invention, soit prévu sur la face intérieure 24 de ce même vantail. Cet organe de détection intérieur est alors associé aux mêmes éléments mécaniques, que l'organe de détection extérieur 3,103,203. En particulier les différentes lignes de transfert, aussi bien côté intérieur que côté extérieur, sont connectées à la platine de commande 6. En service il convient de s'assurer que, dans tous les cas, cette platine est apte à bien distinguer le diagnostic émis à l'encontre de l'élément de détection intérieur, par rapport à celui émis à l'encontre de l'élément de détection extérieur.In the above we have only described the detection member 3,103,203, in accordance with the invention, equipping the
Par ailleurs, dans ce qui précède, on a décrit l'utilisation d'un élément de détection conforme à l'invention, sur une porte de véhicule de transport. L'invention trouve également son application à des portes palières, encore dénommées façades de quai, qui sont équipées d'au moins un tel élément de détection.Furthermore, in the above, the use of a detection element according to the invention has been described, on a transport vehicle door. The invention also finds its application to landing doors, also called platform facades, which are equipped with at least one such detection element.
