If, for example, a body of a vehicle to be manufactured is picked up by the mobile part, the rear edge is further away from the camera of the mobile part. If a rear light is then also attached to the body, the rear edge is even further away from the camera. Since this picking up and attachment takes place in predetermined areas of the trajectory of the mobile part, the distance between the rear edge and the camera can be uniquely assigned and / or defined depending on the position of the mobile part within the system.

Der Erfindung liegt daher die Aufgabe zugrunde, bei einem Schienensystem die Sicherheit weiterzubilden. The invention is therefore based on the object of improving the safety of a rail system.
Erfindungsgemäß wird die Aufgabe bei dem Verfahren nach den in Anspruch 1 und bei dem System nach den in Anspruch 13 angegebenen Merkmalen gelöst. According to the invention the object is achieved in the method according to the features specified in claim 1 and in the system according to the features specified in claim 13.
Wichtige Merkmale der Erfindung bei dem Verfahren sind, dass das Verfahren zum Betreiben eines Systems mit erstem und weiteren Mobilteilen und einer stationär angeordneten Steuerung ausgeführt ist,
wobei das System eine Datenaustauschverbindung zwischen der Steuerung und dem ersten Mobilteil sowie eine Datenaustauschverbindung zwischen der Steuerung und den weiteren Mobilteilen aufweist, wobei in einem ersten Verfahrensschritt das erste Mobilteil seine Position P1 erfasst und/oder die Position seiner Hinterkante H bestimmt und danach die bestimmten Werte, insbesondere die Position P1 und die Position der Hinterkante H, an die Steuerung übermittelt, insbesondere wobei die Fahrtrichtung des ersten Mobilteils erfasst und an die Steuerung übermittelt wird oder wobei abhängig von der Position des ersten Mobilteils eine Fahrtrichtung in der Steuerung hinterlegt ist und an das erste Mobilteil übermittelt wird und/oder als Soll-Fahrtrichtung dem Mobilteil vorgegeben wird, wobei die weiteren Mobilteile jeweils ihre Position P2 erfassen und/oder die Position ihrer Vorderkanten V bestimmen und die bestimmten Werte, insbesondere die Position P2 und die Position der Vorderkante V, an die Steuerung übermitteln, und wobei in einem zweiten Verfahrensschritt die Steuerung das zum ersten Mobilteil nächstbenachbarte und nachfolgende der weiteren Mobilteile bestimmt und diesem dann die Position P1 und/oder die Position der Hinterkante H des ersten Mobilteils übermittelt, und wobei in einem dritten Verfahrensschritt das nachfolgende Mobilteil seinen Bremsweg A, dem zusätzlich ein Sicherheitsabstand und ein Sicherheitsbereich W hinzuaddiert ist, insbesondere welcher vorhandene Reaktionszeiten, Totzeiten und dergleichen berücksichtigt, der Position P2 und/oder der Vorderkante V des nächstbenachbarte nachfolgende Mobilteils hinzuaddiert und diese errechnete Position auf Kollision mit der Hinterkante H des ersten Mobilteils überwacht. Important features of the invention in the method are that the method is designed to operate a system with first and further mobile parts and a stationary controller, The system has a data exchange connection between the controller and the first mobile part and a data exchange connection between the controller and the further mobile parts, wherein in a first method step the first mobile part detects its position P1 and / or determines the position of its trailing edge H and then the determined values , in particular the position P1 and the position of the rear edge H, are transmitted to the controller, in particular wherein the direction of travel of the first mobile part is detected and transmitted to the controller, or a direction of travel is stored in the controller depending on the position of the first mobile part and to which The first mobile part is transmitted and / or is specified as the target direction of travel for the mobile part, the other mobile parts each recording their position P2 and / or determining the position of their front edges V and the determined values, in particular the position P2 and the position of the front edge V, to the tax transmission, and in a second process step the controller determines the next and subsequent one of the other mobile parts and then transmits the position P1 and / or the position of the rear edge H of the first mobile part to it, and in a third process step the following mobile part its braking distance A, to which a safety distance and a safety area W is added, in particular which takes existing reaction times, dead times and the like into account, adds to position P2 and / or the front edge V of the next neighboring mobile part and this calculated position for a collision with the rear edge H of the first handset monitored.
Von Vorteil ist dabei, dass der Position, also dem entsprechenden Positionsvektor, ein Weg, also ein Vektor, aufaddiert wird und somit eine Überwachung einfach ausführbar ist. Da das Mobilteil sich entlang einer Bahnkurve, die durch Schienen oder eine Spurführung

The advantage here is that a worker can stay in the space between two mobile parts and is not injured because a sufficiently large minimum distance is safety-oriented, that is, with a non-trivial, especially high safety category, can be maintained.
Bei einer vorteilhaften Ausgestaltung weist zur jeweiligen Erfassung der jeweiligen Position das erste Mobilteil eine Kamera auf, in deren empfindlichen Bereich parallel zur Fahrtrichtung hintereinander, insbesondere einen Codierbereich bildenden, Codierungen angeordnet sind, insbesondere stationär angeordnet sind. Von Vorteil ist dabei, dass die Codierungen die Information über ihre jeweilige Position enthalten und somit durch Erkennung der Codierungen mittels der Kamera die Position detektierbar ist. In an advantageous embodiment, for the respective detection of the respective position, the first mobile part has a camera, in whose sensitive area codes are arranged one behind the other parallel to the direction of travel, in particular codes forming a coding area, in particular are arranged stationary. The advantage here is that the codes contain the information about their respective position and thus the position can be detected by recognizing the codes by means of the camera.
Bei einer vorteilhaften Ausgestaltung wird zur jeweiligen Erfassung der jeweiligen Geschwindigkeit die zeitliche Abfolge der jeweils erfassten Positionen ausgewertet. Von Vorteil ist dabei, dass die Geschwindigkeit in einfacher Weise bestimmbar ist. In an advantageous embodiment, the chronological sequence of the positions recorded in each case is evaluated for the respective detection of the respective speed. The advantage here is that the speed can be determined in a simple manner.
Bei einer vorteilhaften Ausgestaltung weist jede Codierung Information über ihre jeweilige Position auf, insbesondere zur Grobpositionierung. Von Vorteil ist dabei, dass eine einfache Positionsbestimmung ausführbar ist. In an advantageous embodiment, each coding has information about its respective position, in particular for rough positioning. The advantage here is that a simple position determination can be carried out.
Bei einer vorteilhaften Ausgestaltung bestimmt eine Auswerteeinheit aus den von der Kamera aufgenommenen Bildern einer ersten der Codierungen den Abstand des Bildes zur Bildmitte und daraus eine Verschiebung der Kamera zu derjenigen Position der Kamera, insbesondere zur Feinpositionierung, bei welcher die Blickrichtung der Kamera von der Bildmitte aus gesehen auftrifft auf die erste Codierung, insbesondere auf den Mittelpunkt der ersten Codierung. Von Vorteil ist dabei, dass eine Feinpositionierung in einfacher Weise ausführbar ist. Denn indem die Verschiebung zur Bildmitte bestimmt wird, ist die Verschienung des Mobilteils zu derjenigen Position in einfacher Weise bestimmbar, in welcher das Mobilteil direkt gegenüber der ersten Codierung angeordnet ist, also die Kamera den geringsten Abstand zur ersten Codierung aufweist. Mathematisch äquivalente Verfahrensschritte sind gleichermaßen durchführbar, beispielsweise statt der in Blickrichtung von der Bildmittel aus zur ersten Codierung hin den kürzesten Abstand ist auch ein definierter Winkel, wie beispielsweise 10°, oder dergleichen vorgebbar.
Bei einer vorteilhaften Ausgestaltung wird die am ersten Mobilteil erfasst Fahrtrichtung überwacht, wenn der Abstand zwischen der Position der Hinterkante H des ersten Mobilteils und der Position der Vorderkante des nächstbenachbarten nachfolgenden Mobilteils einen Schwellwert unterschreitet. Von Vorteil ist dabei, dass eine Kollisionsüberwachung in einfacher Weise ermöglicht ist. In an advantageous embodiment, an evaluation unit determines the distance of the image to the center of the image from the images recorded by the camera of a first of the codes and, from this, a shift of the camera to that position of the camera, in particular for fine positioning, in which the viewing direction of the camera is from the center of the image seen occurs on the first coding, in particular on the center of the first coding. The advantage here is that fine positioning can be carried out in a simple manner. Because by determining the shift to the center of the image, the shifting of the mobile part to that position can be determined in a simple manner in which the mobile part is arranged directly opposite the first coding, i.e. the camera is the smallest distance from the first coding. Mathematically equivalent method steps can equally be carried out, for example instead of the shortest distance in the viewing direction from the image means to the first coding, a defined angle, such as 10 ° or the like, can also be specified. In an advantageous embodiment, the direction of travel detected on the first mobile part is monitored when the distance between the position of the rear edge H of the first mobile part and the position of the front edge of the next adjacent following mobile part falls below a threshold value. The advantage here is that collision monitoring is made possible in a simple manner.
Bei einer vorteilhaften Ausgestaltung wird die am ersten Mobilteil erfasste Fahrtrichtung nicht überwacht, wenn der Abstand zwischen der Position der Hinterkante H des ersten Mobilteils und der Position der Vorderkante des nächstbenachbarten nachfolgenden Mobilteils den Schwellwert überschreitet, wobei dann das erste Mobilteil mittels eines Handbediengeräts, insbesondere in Rückwärtsrichtung, steuerbar ist, insbesondere wobei das Handbediengerät mittels eines elektrischen Kabels mit dem ersten Mobilteil verbunden ist. Von Vorteil ist dabei, dass eine Handsteuerung ausführbar ist, wenn genügend Abstand vorhanden ist. In an advantageous embodiment, the direction of travel detected on the first mobile part is not monitored if the distance between the position of the rear edge H of the first mobile part and the position of the front edge of the next adjacent following mobile part exceeds the threshold value, the first mobile part then using a handheld control device, in particular in Reverse direction, is controllable, in particular wherein the hand-held device is connected to the first mobile part by means of an electrical cable. The advantage here is that manual control can be carried out if there is sufficient distance.
Bei einer vorteilhaften Ausgestaltung ermittelt das erste Mobilteil aus seiner Position P1 die Position seiner Hinterkante H, insbesondere abhängig von seiner Position P1 in dem System, insbesondere wobei bei unterschiedlichen Positionen vom ersten Mobilteil unterschiedlichen Lasten aufgenommen sind. Von Vorteil ist dabei, dass bei einer Fertigungsstraße die Hinterkante H durch den Einbau oder die Aufnahme von zusätzlichen Teilen immer weiter von der Kamera entfernt ist und trotzdem die Beabstandungen sicherheitsgerichtet einhaltbar sind. Wenn also beispielsweise eine Karosserie eines zu fertigenden Fahrzeugs vom Mobilteil aufgenommen wird, ist die Hinterkante weiter von der Kamera des Mobilteils entfernt. Wird dann zusätzlich noch eine Rückleuchte an der Karosserie angebracht, ist die Hinterkante von der Kamera noch weiter entfernt. Da dieses Aufnehmen und Anbringen in vorgegebenen Bereichen der Bahnkurve des Mobilteils erfolgt, ist abhängig von der Position des Mobilteils innerhalb der Anlage der Abstand der Hinterkante von der Kamera eineindeutig zuordenbar und/oder definiert. In an advantageous embodiment, the first mobile part determines the position of its rear edge H from its position P1, in particular as a function of its position P1 in the system, in particular with different loads being absorbed by the first mobile part in different positions. The advantage here is that, in a production line, the rear edge H is always further removed from the camera due to the installation or the inclusion of additional parts and the spacing can nevertheless be maintained in a safety-oriented manner. If, for example, a body of a vehicle to be manufactured is picked up by the mobile part, the rear edge is further away from the camera of the mobile part. If a rear light is then also attached to the body, the rear edge is even further away from the camera. Since this picking up and attachment takes place in predetermined areas of the trajectory of the mobile part, the distance between the rear edge and the camera can be uniquely assigned and / or defined depending on the position of the mobile part within the system.
Bei einer vorteilhaften Ausgestaltung ermittelt das jeweilige, insbesondere das nächstbenachbarte, Mobilteil aus seiner Position P1 die Position seiner Hinterkante H,
insbesondere abhängig von seiner Position in dem System, insbesondere wobei bei unterschiedlichen Positionen vom jeweiligen Mobilteil unterschiedlichen Lasten aufgenommen sind. Von Vorteil ist dabei, dass wiederum abhängig vom Bereich der Bahnkurve die Entfernung der Hinterkante von der Kamera definiert ist. In an advantageous embodiment, the respective, in particular the next adjacent, mobile part determines the position of its rear edge H from its position P1, in particular depending on its position in the system, in particular with different loads being absorbed by the respective mobile part in different positions. The advantage here is that the distance of the trailing edge from the camera is again defined depending on the area of the trajectory.
Wichtige Merkmale bei dem System zur Durchführung eines vorgenannten Verfahrens sind, dass die Mobilteile schienengeführt sind und die Codierungen sich parallel zur Schienenrichtung erstrecken. Important features of the system for carrying out the aforementioned method are that the mobile parts are rail-guided and the codings extend parallel to the rail direction.
Von Vorteil ist dabei, dass die Schienenposition sicher gewährleistbar ist, indem das Mobilteil mechanisch geführt ist. Außerdem sind die Berechnungen eindimensional ausführbar und somit einfache und schnell ausführbar. The advantage here is that the rail position can be reliably guaranteed by the mobile part being guided mechanically. In addition, the calculations can be carried out one-dimensionally and can therefore be carried out quickly and easily.
Bei einer vorteilhaften Ausgestaltung weist das Mobilteil einen elektromotorischen Antrieb auf. Von Vorteil ist dabei, dass das Mobilteil einen Energiespeicher, wie Batterie und/oder Akkumulator und/oder induktiv oder konduktiv mit elektrischer Energie während der Fahrt versorgbar ist. Bei konduktiver Versorgung ist entlang der Schienen eine Schleifleitung verlegt; bei induktiver Versorgung ist entlang der Bahnkurve, insbesondere entlang der Schiene, ein Primärleiter verlegt, der induktiv koppelbar ist mit einer am Mobilteil angeordneten Sekundärwicklung, der eine Kapazität in Reihe oder parallel derart zugeschaltet ist, dass die Resonanzfrequenz des so entstandenen Schwingkreises der Frequenz des in den Primärleiter eingespeisten Wechselstromes gleicht. Der Primärleiter ist hierbei als langgestreckt ausgeführter Linienleiter, bestehend aus HF-Litze, ausgeführt, wobei die Frequenz zwischen 10 kHz und 1000 kHz beträgt. In an advantageous embodiment, the mobile part has an electric motor drive. The advantage here is that the mobile part can be supplied with an energy store, such as a battery and / or accumulator and / or inductively or conductively, with electrical energy while driving. In the case of a conductive supply, a conductor line is laid along the rails; In the case of inductive supply, a primary conductor is laid along the trajectory, in particular along the rail, which can be inductively coupled to a secondary winding arranged on the mobile part, to which a capacitance is connected in series or in parallel in such a way that the resonance frequency of the resulting resonant circuit matches the frequency of the in equals the primary conductor fed in alternating current. The primary conductor is designed as an elongated line conductor, consisting of HF litz wire, the frequency being between 10 kHz and 1000 kHz.
Bei einer vorteilhaften Ausgestaltung weist das Mobilteil einen Spurführungssensor auf oder ist das Mobilteil ein Schienenfahrzeug. Von Vorteil ist dabei, dass das Mobilteil sich eindimensional bewegt und daher die Berechnungen einfach und schnell ausführbar sind. In an advantageous embodiment, the mobile part has a tracking sensor or the mobile part is a rail vehicle. The advantage here is that the mobile part moves one-dimensionally and therefore the calculations can be carried out quickly and easily.
Weitere Vorteile ergeben sich aus den Unteransprüchen. Die Erfindung ist nicht auf die Merkmalskombination der Ansprüche beschränkt. Für den Fachmann ergeben sich weitere sinnvolle Kombinationsmöglichkeiten von Ansprüchen und/oder einzelnen Anspruchsmerkmalen und/oder Merkmalen der Beschreibung und/oder der Figuren, insbesondere aus der Aufgabenstellung und/oder der sich durch Vergleich mit dem Stand der Technik stellenden Aufgabe.
Die Erfindung wird nun anhand von schematischen Abbildungen näher erläutert: Further advantages result from the subclaims. The invention is not restricted to the combination of features of the claims. For the person skilled in the art, there are further meaningful possible combinations of claims and / or individual claim features and / or features of the description and / or the figures, in particular from the task and / or the task posed by comparison with the prior art. The invention will now be explained in more detail with reference to schematic figures:
In der Figur 1 ist ein erfindungsgemäßes System schematisch dargestellt. A system according to the invention is shown schematically in FIG.
Wie in der Figur dargestellt, folgt einem ersten Mobilteil 1 ein zweites Mobilteil 2, wobei ein sicherer Abstand gewährleistet wird. As shown in the figure, a first mobile part 1 is followed by a second mobile part 2, a safe distance being ensured.
Hierzu erfasst das erste Mobilteil 1 seine Position P1 mit einem ersten Positionserfassungssystem und das zweite Mobilteil 2 seine Position P2. For this purpose, the first mobile part 1 detects its position P1 with a first position detection system and the second mobile part 2 detects its position P2.
Vorzugsweise sind die beiden Mobilteile (1, 2) spurgeführt oder schienengeführt. The two mobile parts (1, 2) are preferably track-guided or rail-guided.
Als Positionserfassungssystem ist vorzugsweise ein mit Codierungen versehener Codierbereich entlang der Bahnkurve der Mobilteile (1, 2), insbesondere entlang der Schienen, angeordnet. Jede der Codierungen codiert seine jeweilige Position. A coding area provided with coding is preferably arranged as the position detection system along the trajectory of the mobile parts (1, 2), in particular along the rails. Each of the codes codes its respective position.
Die Mobilteile weisen abhängig von der jeweils aufgenommenen Last eine jeweilige Länge auf. Somit ist es dem ersten Mobilteil 1 ermöglicht, die Position H seiner Hinterkante zu bestimmen, und dem zweiten Mobilteil 2, die Position V seiner Vorderkante zu bestimmen. The mobile parts have a respective length depending on the load taken. It is thus possible for the first mobile part 1 to determine the position H of its rear edge and the second mobile part 2 to determine the position V of its front edge.
Außerdem erfasst das erste Mobilteil 1 seine Bewegungsrichtung R1 sowie seine Geschwindigkeit V1 und das zweite Mobilteil 2 seine Bewegungsrichtung R2 sowie seine Geschwindigkeit V2. In addition, the first mobile part 1 records its direction of movement R1 and its speed V1 and the second mobile part 2 records its direction of movement R2 and its speed V2.
Im ersten Mobilteil 1 wird eine Richtungsüberwachung ausgeführt. Dabei wird die Bewegungsrichtung R1 überwacht auf Vorwärtsfahrt. Sobald also eine Rückwärtsbewegung des ersten Mobilteils 1 von diesem selbst detektiert wird, wird ein Fehlersignal erzeugt und weitergemeldet, was ein Stoppen der Mobilteile (1, 2) des Systems bewirkbar macht. Direction monitoring is carried out in the first mobile part 1. The direction of movement R1 is monitored for forward travel. As soon as the first mobile part 1 itself detects a backward movement, an error signal is generated and reported, which makes it possible to stop the mobile parts (1, 2) of the system.
Jedes der Mobilteile (1, 2) meldet seine Position P1 beziehungswiese P2 an eine Steuerung 3. Hierzu besteht seine nicht leitungsgebundene Datenaustauschverbindung zwischen der Steuerung 3 und den Mobilteilen (1, 2).
Zum Einhalten des sicheren Abstandes meldet zunächst das erste Mobilteil 1 seine Position P1 und insbesondere die Position seiner Hinterkante H an die Steuerung 3, welche dann das nächstbenachbarte Mobilteil 2 aus allen, von Mobilteilen (1, 2) erhaltenen Positionsdaten bestimmt. Each of the mobile parts (1, 2) reports its position P1 or P2 to a controller 3. For this purpose, there is a non-wired data exchange connection between the controller 3 and the mobile parts (1, 2). To maintain the safe distance, the first mobile part 1 first reports its position P1 and in particular the position of its rear edge H to the controller 3, which then determines the nearest mobile part 2 from all the position data received from the mobile parts (1, 2).
Die Steuerung 3 übermittelt dem zweiten Mobilteil 2 die vom ersten Mobilteil 1 erhaltenen Daten, wie Position P1 und Hinterkantenposition H. The controller 3 transmits to the second mobile part 2 the data received from the first mobile part 1, such as position P1 and rear edge position H.
Das zweite Mobilteil berechnet unter Berücksichtigung seiner von ihm erfassten Geschwindigkeit V2 und der ihm maximal verfügbaren Bremsbeschleunigung einen Bremsweg A, dem auch zusätzlich ein Sicherheitsabstand hinzuaddiert ist, der vorhandene Reaktionszeiten, Totzeiten und dergleichen berücksichtigt. Durch Addition dieses so bestimmten Bremsweges A zu der vom zweiten Mobilteil 2 selbst erfassten Position P2 des zweiten Mobilteils 2 und Hinzufügen eines weiteren für einen Menschen vorgesehenen Sicherheitsbereichs W wird diejenige Position bestimmt, welche mit der Hinterkantenposition H des ersten Mobilteils 1 verglichen wird. Sobald ein unzulässiges Maß an Abweichung zu dieser Hinterkantenposition H von der durch Addition entstandenen Position unterschritten wird, wird ein Fehlersignal, insbesondere STO Signal, erzeugt und der Fehler weitergemeldet, insbesondere werden die Antriebe der Mobilteil zum Stillstand gebracht. The second mobile part, taking into account its detected speed V2 and the maximum braking acceleration available to it, calculates a braking distance A to which a safety margin is also added, which takes into account existing reaction times, dead times and the like. By adding this braking distance A determined in this way to the position P2 of the second mobile part 2 detected by the second mobile part 2 itself and adding a further safety area W intended for a person, that position is determined which is compared with the rear edge position H of the first mobile part 1. As soon as an inadmissible amount of deviation from this rear edge position H from the position resulting from the addition is undershot, an error signal, in particular an STO signal, is generated and the error is reported, in particular the drives of the mobile part are brought to a standstill.
Mit anderen Worten ausgedrückt, wird die Vorderkantenposition V des zweiten Mobilteils 2 auf Kollision mit der Hinterkantenposition H des ersten Mobilteils 1 überwacht. In other words, the leading edge position V of the second mobile part 2 is monitored for collision with the rear edge position H of the first mobile part 1.
Wenn der Abstand zwischen der Hinterkantenposition H und der Vorderkantenposition V einen Schwellwert s überschreitet, also genügend groß ist, wird die Richtungsüberwachung des ersten Mobilteils 1 ausgeschaltet. Somit ist eine Rückwärtsfahrt des ersten Mobilteils 1 erlaubt. Dies ist beispielsweise vorteilhaft anwendbar in einem Wartungsbereich oder in einem Abstellgleis. If the distance between the rear edge position H and the front edge position V exceeds a threshold value s, that is to say is sufficiently large, the direction monitoring of the first mobile part 1 is switched off. Reversing the first mobile part 1 is thus permitted. This can be advantageously used, for example, in a maintenance area or in a siding.
Dort kann mit einem Handbediengerät eine Rückwärtsfahrt des ersten Mobilteils 1 gesteuert werden. Bei eingeschalteter Richtungsüberwachung ist eine Steuerung des ersten Mobilteils 1 mit dem Handbediengerät nicht ausführbar.
Die genannten Bestimmungen und Überwachungen sind in sicherer Technik ausgeführt. Somit ist eine verbesserte Sicherheit erreichbar, insbesondere eine höhere Sicherheitskategorie.
There, reversing of the first mobile part 1 can be controlled with a handheld control unit. When the direction monitoring is switched on, it is not possible to control the first mobile part 1 with the handheld control unit. The specified provisions and monitoring are carried out using safe technology. Improved security can thus be achieved, in particular a higher security category.
