Description

Die vorliegende Erfindung betrifft ein Verfahren zur Diagnose von Subsystemen in Schienenfahrzeugen sowie eine Vorrichtung, die die Durchführung des erfindungsgemäßen Diagnoseverfahrens ermöglicht. Des Weiteren umfasst die Erfindung die Verwendung einer übergeordneten Steuereinheit und mindestens eines ihr untergeordneten Subsystem-Steuergeräts zur Durchführung einer Diagnose sowie ein computergestütztes Verfahren zur Ausführung des Verfahrens.The present invention relates to a method for diagnosing subsystems in rail vehicles and a device that enables the diagnostic method according to the invention to be carried out. The invention also includes the use of a higher-level control unit and at least one subsystem control unit subordinate to it for carrying out a diagnosis and a computer-aided method for carrying out the method.

Die technische Komplexität von Schienenfahrzeugen steigt stetig an. Ehemals relativ einfache, (mechanische) Subsysteme wie z.B. Türen und Klimaanlagen wurden abgelöst durch Subsysteme, die eine Vielzahl von unterschiedlichen Aktuatoren, Sensoren, elektrischen und signaltechnischen Verbindungen enthalten. Dies führt zu verschiedenen Vorteilen im Betrieb des Schienenfahrzeugs, jedoch steigt durch die höhere Anzahl von Bauteilen die Wahrscheinlichkeit, dass eines davon ausfällt.The technical complexity of rail vehicles is constantly increasing. Formerly relatively simple (mechanical) subsystems such as doors and air conditioning systems have been replaced by subsystems that contain a large number of different actuators, sensors, electrical and signaling connections. This leads to various advantages in the operation of the rail vehicle, but the higher number of components increases the probability that one of them will fail.

Heutige Schienenfahrzeuge verfügen über ein Diagnosesystem, das fehlerhafte Komponenten im Rahmen ihrer betrieblichen Nutzung erkennt und meldet. Erweiterte Tests des Gesamtsystems Schienenfahrzeug finden darüber hinaus im Wartungsdepot statt. In diesem Zusammenhang beschreibt die OffenlegungsschriftToday's rail vehicles have a diagnostic system that detects and reports faulty components as part of their operational use. Extended tests of the entire rail vehicle system are also carried out in the maintenance depot. In this context, the disclosure document describes

WO 2016/102160 A1 ein Verfahren zur Diagnose von Schienenfahrzeugen, das auf dem Anschluss einer stationären Steuereinheit und einer Simulationseinheit basiert, die auf der Landseite bereitgestellt werden. Die Diagnose der Systeme erfolgt nach Erstellen einer Datenverbindung zwischen Steuereinheit, Simulationseinheit und Schienenfahrzeug durch anschließendes Durchlaufen eines Diagnoseprogramms. Nachteilig an dieser Lösung sind die Tatsachen, dass die beschriebene Simulationseinheit und die Steuereinheit zur Durchführung entweder bereits vor Ort, z.B. im Depot, vorhanden sein müssen oder aber an Bord des Schienenfahrzeugs mitgeführt werden müssen, um dann bei Diagnosebedarf aufgestellt und angeschlossen zu werden. Je nach Komplexität der Steuer- und Simulationseinheit sowie der notwendigen elektrischen bzw. signaltechnischen Verbindungen ist zur Initiierung des notwendigen Diagnosevorgangs geschultes oder zumindest eingewiesenes Personal erforderlich. WO 2016/102160 A1 a method for diagnosing railway vehicles based on the connection of a stationary control unit and a simulation unit provided on the land side. The systems are diagnosed after a data connection has been established between the control unit, simulation unit and rail vehicle and a diagnostic program is then run through. A disadvantage of this solution is the fact that the simulation unit described and the control unit must either already be present on site, for example in the depot, or must be carried on board the rail vehicle in order to be set up and connected when diagnostics are required. Depending on the complexity of the control and simulation unit and the necessary electrical or signaling connections trained or at least instructed staff is required to initiate the necessary diagnostic process.

Für zukünftige Schienenfahrzeuge besteht die Anforderung, technische Probleme vor ihrem tatsächlichen Auftreten erkennen zu können, um z.B. durch vorausschauenden Austausch von Komponenten einen störungsfreien Betriebsablauf zu gewährleisten. Dokument US 8 386 122 B1 offenbart Techniken zum selbsttätigen Testen von Systemkomponenten eines Schienenfahrzeugs. In einer Ausführungsform wird ein Subsystem in einen Testsignalumsetzungsmodus versetzt und Testsignale werden durch eine übergeordnete Steuereinheit vorgegeben. Das Subsystem stellt Testsignalantworten zur Verfügung, die von der übergeordneten Steuereinheit empfangen und ausgewertet werden.For future rail vehicles, there is a requirement to be able to identify technical problems before they actually occur in order to ensure trouble-free operation, for example, through the proactive replacement of components. document U.S. 8,386,122 B1 discloses techniques for self-testing of rail vehicle system components. In one embodiment, a subsystem is put into a test signal conversion mode and test signals are specified by a higher-level control unit. The subsystem provides test signal responses that are received and evaluated by the higher-level control unit.

Der Erfindung liegt daher die Aufgabe zu Grunde, ein Verfahren zur erweiterten Diagnose von Subsystemen bereitzustellen, das einen geringen personellen und zeitlichen Aufwand zur Durchführung der erweiterten Diagnose erfordert sowie nur bereits auf dem Schienenfahrzeug vorhandene Diagnosegeräte verwendet.The invention is therefore based on the object of providing a method for the extended diagnosis of subsystems, which requires little effort in terms of personnel and time to carry out the extended diagnosis and only uses diagnosis devices that are already present on the rail vehicle.

Diese Aufgabe wird mit den Merkmalen der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.This object is solved with the features of the independent claims. Advantageous developments are the subject of the subclaims.

Zur Lösung dieser Aufgabe wird vorgeschlagen, ein Verfahren zur Diagnose von Subsystemen in Schienenfahrzeugen mit Hilfe bereits für den Normalbetrieb des Schienenfahrzeugs vorgesehener Steuereinheiten und Steuergeräte durchzuführen, wobei ein Subsystem-Steuergerät in einen Testsignal-Umsetzungsmodus versetzt wird, in dem die für den Normalbetrieb vorgesehenen Funktionen deaktiviert werden.To solve this problem, it is proposed to carry out a method for diagnosing subsystems in rail vehicles using control units and control units already provided for normal operation of the rail vehicle, a subsystem control unit being switched to a test signal conversion mode in which the functions provided for normal operation be deactivated.

Subsysteme an Bord von Schienenfahrzeugen enthalten eigene Subsystem-Steuergeräte, die über eine für ihre Kernaufgabe ausgelegte Rechenleistung verfügen. Die Subsystem-Steuergeräte verfügen über signaltechnische Ein- und Ausgänge zur Kommunikation mit der übergeordneten Steuereinheit und zur Kommunikation mit den subsystem-eigenen Komponenten.Subsystems on board rail vehicles contain their own subsystem control units, which have the computing power designed for their core task. The subsystem control devices have signaling inputs and outputs for communication with the higher-level control unit and for communication with the subsystem's own components.

Subsysteme können über eine integrierte Selbstdiagnose verfügen. Allerdings erfordert dies eine lieferantenseitige Konfiguration des Subsystem-Steuergerätes, was insofern nachteilig ist, als dass dieses Subsystem-Steuergerät dann nur für diesen speziellen Anwendungsfall verwendet werden kann. Sofern eine subsystemübergreifende Diagnose gewünscht ist, muss dies also schon vor Auslieferung der später zusammenwirkenden Subsystem-Steuergeräte bekannt sein.Subsystems can have built-in self-diagnostics. However, this requires the supplier to configure the subsystem control device, which is disadvantageous in that this subsystem control device can then only be used for this special application. If a cross-subsystem diagnosis is desired, this must be known before delivery of the subsystem control units that will later interact.

Das Zusammenwirken der verschiedenen Subsysteme eines Schienenfahrzeugs wird über mindestens eine übergeordnete Steuereinheit gesteuert. Die Rechenleistung der übergeordneten Steuereinheit sowie der Subsystem-Steuergeräte ist so ausgelegt, dass deren Funktion, welche auch ein komplexes Zusammenspiel der Subsysteme sein kann, im Normalbetrieb gewährleistet wird, ohne dass signifikante Reserven für andere Aufgaben vorgehalten werden.The interaction of the various subsystems of a rail vehicle is controlled by at least one higher-level control unit. The computing power of the higher-level control unit and the subsystem control units is designed in such a way that their function, which can also be a complex interaction of the subsystems, is guaranteed in normal operation without having significant reserves for other tasks.

In längeren Phasen des Fahrzeugstillstands werden die für den Normalbetrieb vorgesehenen Funktionen nicht benötigt. Daher können bei Anwendung des erfindungsgemäßen Verfahrens die Subsystem-Steuergeräte in diesen Phasen in einen Testsignal-Umsetzungsmodus versetzt werden, in dem die für den Normalbetrieb vorgesehenen Funktionen deaktiviert werden.The functions intended for normal operation are not required during longer phases when the vehicle is stationary. Therefore, when using the method according to the invention, the subsystem control devices can be put into a test signal conversion mode in these phases, in which the functions provided for normal operation are deactivated.

Somit kann die Rechenleistung der Subsystem-Steuergeräte allein für die Umsetzung der von der übergeordneten Steuereinheit vorgegebenen Testsignale verwendet werden. "Umsetzung" bedeutet in diesem Zusammenhang die Ausgabe der von der übergeordneten Steuereinheit vorgegebenen Testsignale an die zu testenden Subsystem-Komponenten. Dies kann sowohl ohne als auch mit Konvertierungsmechanismen gemäß den Vorgaben durch die übergeordnete Steuereinheit erfolgen. So kann die Charakteristik des Testsignals durch eine Regel vorgegeben werden (z.B. Sinus-Signal, Rechteck-Signal), welche das Subsystem-Steuergerät anwendet, um den Verlauf des Testsignals auszugeben. Alternativ kann das Testsignal über die Vorgabe von diskreten Einzelwerten erfolgen.In this way, the computing power of the subsystem control units can be used solely for the conversion of the test signals specified by the higher-level control unit. In this context, "implementation" means the output of the test signals specified by the higher-level control unit to the subsystem components to be tested. This can be done both with and without conversion mechanisms according to the requirements of the higher-level control unit. The characteristics of the test signal can be specified by a rule (e.g. sine signal, square wave signal), which the subsystem controller uses to output the test signal curve. Alternatively, the test signal can be given by specifying discrete individual values.

Die aus den Testsignalen resultierenden Rückmeldungen der zu testenden Subsystem-Komponenten werden zunächst von den Subsystem-Steuergeräten empfangen und in Testsignalantworten für die übergeordnete Steuereinheit umgesetzt. Die Umsetzung kann ihrerseits mit und ohne Konvertierungsmechanismen erfolgen. Die übergeordnete Steuereinheit empfängt die Testsignalantworten der Subsystem-Steuergeräte und wertet diese aus.The feedback from the subsystem components to be tested resulting from the test signals is first received by the subsystem control devices and converted into test signal responses for the higher-level control unit. For its part, the conversion can take place with and without conversion mechanisms. The higher-level control unit receives the test signal responses from the subsystem control units and evaluates them.

Die Vorgabe der Testsignale durch die übergeordnete Steuereinheit ermöglicht eine hohe Flexibilität bzgl. der Art der erzeugten Testsignale. So kann z.B. durch Softwareupdates das Testsignal verändert werden. Sofern die übergeordnete Steuereinheit nicht nur über eine lokale Schnittstelle zur Datenübertragung verfügt, sondern auch oder alternativ über die Möglichkeit der Ferndatenübertragung, so kann ein Softwareupdate auch situationsbezogen erfolgen. Dies kann z.B. dann erforderlich sein, wenn die standardmäßig vorgesehen Testsignalverläufe zwar auf einen Fehler im Gesamtsystem hindeuten, dieser jedoch noch nicht genau lokalisiert werden kann. In diesem Fall kann zur weiteren Diagnose ein speziell angepasster Testverlauf per Softwareupdate installiert werden, um gezielt nach den Fehlerursachen suchen zu können. Das Vorgeben der Testsignale durch die übergeordnete Steuereinheit bietet weiterhin den Vorteil, dass eine werksseitige Konfiguration der Subsystem-Steuergeräte zur Durchführung des Verfahrens nicht notwendig ist.The specification of the test signals by the higher-level control unit enables a high level of flexibility with regard to the type of test signals generated. For example, through software updates the test signal can be changed. If the higher-level control unit not only has a local interface for data transmission, but also or alternatively has the option of remote data transmission, a software update can also be carried out depending on the situation. This can be necessary, for example, if the test signal curves provided as standard indicate an error in the overall system, but this cannot yet be precisely localized. In this case, a specially adapted test procedure can be installed via software update for further diagnosis in order to be able to search specifically for the cause of the error. The specification of the test signals by the higher-level control unit also offers the advantage that a factory configuration of the subsystem control devices is not necessary to carry out the method.

In einer weiteren Ausführungsform werden die von der übergeordneten Steuereinheit vorgegebenen Testsignale vorteilhafterweise so gewählt, dass sie sich zumindest teilweise hinsichtlich Frequenz und/oder Signalstärke und/oder Signaldauer von den im Betrieb des Schienenfahrzeuges auftretenden Frequenzen und/oder Signalverläufen und/oder Signaldauern unterscheiden. Die Wahl der derart erzeugten Testsignale sowie das in Bezug setzen der Testsignalantworten ermöglicht eine präzise Aussage über den Zustand der geprüften Komponenten. Unter Zustand wird hierbei sowohl die reine Funktionsfähigkeit als auch der Funktionsgrad verstanden. Der Funktionsgrad, welcher sich zeitlich relativ langsam verändern kann (z.B. durch Komponentenverschleiß), gibt den aktuellen Zustand einer Komponente an, was Rückschlüsse auf möglicherweise einzuplanende Wartungsaktivitäten erlaubt.In a further embodiment, the test signals specified by the higher-level control unit are advantageously selected such that they differ at least partially in terms of frequency and/or signal strength and/or signal duration from the frequencies and/or signal profiles and/or signal durations occurring during operation of the rail vehicle. The selection of the test signals generated in this way and the correlation of the test signal responses enable a precise statement to be made about the condition of the tested components. In this context, condition is understood to mean both the pure functionality and the degree of functionality. The degree of functionality, which can change relatively slowly over time (e.g. due to component wear), indicates the current condition of a component, which allows conclusions to be drawn about maintenance activities that may need to be scheduled.

In einer weiteren Ausführungsform werden die von der übergeordneten Steuereinheit vorgegebenen Testsignale vorteilhafterweise in Abhängigkeit von Umweltbedingungen, nämlich äußeren Einflussfaktoren, wie z.B. der Außentemperatur oder der Luftfeuchtigkeit o.ä., gewählt so dass die präzise Aussage über den aktuellen Zustand der geprüften Komponente auch diesbezüglich ermöglicht wird. In einer weiteren Ausführungsform werden die von der übergeordneten Steuereinheit empfangenen Testsignalantworten zu den Umweltbedingungen in Bezug gesetzt. Dies ermöglicht ebenfalls eine Berücksichtigung der äußeren Einflussfaktoren für die präzise Aussage über den aktuellen Zustand der geprüften Komponente.In a further embodiment, the test signals specified by the higher-level control unit are advantageously selected as a function of environmental conditions, namely external influencing factors such as outside temperature or humidity or the like, so that precise information about the current status of the tested component is also made possible in this regard becomes. In a further embodiment, the test signal responses received from the higher-level control unit are related to the environmental conditions. This also enables the external influencing factors to be taken into account for the precise statement about the current condition of the tested component.

In einer weiteren Ausführungsform werden die Testsignalantworten mindestens eines der Subsysteme vorteilhafterweise in Bezug gesetzt zu Testsignalantworten mindestens eines weiteren der Subsysteme. Somit können vorgesehene oder unvorgesehene Wechselwirkungen zwischen verschiedenen Subsystemen reproduzierbar erzeugt und ausgewertet werden. Hierbei erfolgt also nicht nur die Diagnose eines einzelnen der Subsysteme, sondern es wird das Zusammenspiel der verschiedenen Subsysteme und deren Komponenten geprüft.In a further embodiment, the test signal responses of at least one of the subsystems are advantageously related to the test signal responses of at least one other of the subsystems. In this way, intended or unintended interactions between different subsystems can be generated and evaluated in a reproducible manner. In this case, not only is the diagnosis of an individual subsystem carried out, but the interaction of the various subsystems and their components is checked.

In einer weiteren Ausführungsform werden vorteilhafterweise Testsignalantworten mindestens eines der Subsysteme in Bezug gesetzt zu der erwarteten Funktion des Subsystems oder dessen Komponenten. Wird eines der Subsysteme mit einem Testsignal beaufschlagt, liefert dieses im Regelfall eine erwartete Testsignalantwort. In dem Fall, in dem die Testsignalantwort von der erwarteten Testsignalantwort abweicht, kann dieses auf einen bereits vorliegenden oder sich noch entwickelnden Fehler hindeuten. Eine genaue Lokalisierung und Bestimmung des Fehlers kann erfolgen, indem das Testsignal in der Folge variiert und die Testsignalantwort erneut in Bezug zu dem ursprünglichen Testsignal gesetzt wird.In a further embodiment, test signal responses of at least one of the subsystems are advantageously related to the expected function of the subsystem or its components. If a test signal is applied to one of the subsystems, it usually supplies an expected test signal response. If the test signal response deviates from the expected test signal response, this can indicate an error that is already present or is still developing. Accurate location and determination of the fault can be made by varying the test signal in sequence and re-relating the test signal response to the original test signal.

In einer weiteren Ausführungsform werden vorteilhafterweise aus Testsignalantworten eines der Subsysteme Informationen über den Alterungs- und Verschleißzustand dessen Komponenten abgeleitet. Beispielhaft kann der Zustand eines Magnetventils darüber ermittelt werden, bei welcher Spannung ein Schaltzeitpunkt erreicht wird. In diesem Beispiel wäre die Spannung ein von einer übergeordneten Steuereinheit vorgegebenes Testsignal, während das Schalten des Ventils eine Testsignalantwort liefert. Sofern ein Schalten des Ventils nicht bei einer sonst üblichen Spannung erfolgt, kann dies ein Hinweis für einen möglichen Verschleiß des Magnetventils sein. Dieses bedingt jedoch nicht, dass das Magnetventil im Normalbetrieb nicht mehr korrekt funktionieren würde.In a further embodiment, information about the aging and wear status of its components is advantageously derived from test signal responses from one of the subsystems. For example, the state of a solenoid valve can be determined by the voltage at which a switching point is reached. In this example, the voltage would be a test signal specified by a higher-level control unit, while the switching of the valve provides a test signal response. If the valve does not switch at an otherwise normal voltage, this can be an indication of possible wear on the solenoid valve. However, this does not mean that the solenoid valve would no longer function correctly in normal operation.

Die erfindungsgemäße Verwendung der an sich bekannten Komponenten "übergeordnete Steuereinheit" und "Subsystem-Steuergerät" ermöglicht, dass eine performante Diagnose mit Überschreitung von Subsystem-Grenzen möglich ist. Die Vorgabe von Testsignalen über die übergeordnete Steuereinheit ermöglicht die Durchführung komplexer Diagnosen der Subsysteme, und zwar ohne die Installation zusätzlicher Hardware-Komponenten bzw. ohne Modifikation des bereits für den Betrieb ausgerüsteten Schienenfahrzeugs.The use according to the invention of the components “superordinate control unit” and “subsystem control unit” which are known per se makes it possible for high-performance diagnosis to be carried out when subsystem limits are exceeded. the Specification of test signals via the higher-level control unit enables complex diagnostics of the subsystems to be carried out without the installation of additional hardware components or without modification of the rail vehicle already equipped for operation.

Erfindungsgemäß weist ein computergestütztes Verfahren zur Diagnose der Subsysteme zumindest teilweise die vorangehend genannten Verfahrensschritte auf.According to the invention, a computer-assisted method for diagnosing the subsystems has at least some of the method steps mentioned above.

Das Verfahren mit zumindest einem Teil der vorangehend genannten Verfahrensschritte wird auf einer dazu konfigurierten erfindungsgemäßen Vorrichtung ausgeführt.The method with at least some of the method steps mentioned above is carried out on a device according to the invention configured for this purpose.

Wenn die Subsysteme der Vorrichtung vorteilhafterweise miteinander in Verbindung stehen, kann auch ein direktes Zusammenwirken der Subsysteme diagnostiziert werden.If the subsystems of the device are advantageously connected to one another, a direct interaction of the subsystems can also be diagnosed.

Fig. 1 zeigt ein Zugnetzwerk 3, an das eine übergeordnete Steuereinheit 4 sowie eine Mehrzahl von Subsystem-Steuergeräten 1a, 1b,..., 1f angeschlossen sind. Das Zugnetzwerk umfasst in diesem Beispiel zwei Wagen bzw. Zugteile W1 und W2, die miteinander gekoppelt sind, d.h. die Zugteile W1 und W2 können über das Zugnetzwerk 3 miteinander kommunizieren. Im Normalbetrieb steuert die übergeordnete Steuereinheit 4 die Subsystem-Steuergeräte 1a, 1b,..., 1f über das Zugnetzwerk derart, dass diese mit ihren Subsystem-Komponenten (Mechanik/Elektromechanik) 2a, 2b,..., 2f kommunizieren, wie es zur Gewährleistung ihrer Funktionen im Normalbetrieb erforderlich ist. Die Kommunikation zwischen der übergeordneten Steuereinheit 4, den Subsystem-Steuergeräten 1a, 1b,..., 1f und den Subsystem-Komponenten 2a, 2b,..., 2f ist anhand von durchgezogenen Pfeilen dargestellt. 1 shows a train network 3 to which a higher-level control unit 4 and a plurality of subsystem control units 1a, 1b, . . . , 1f are connected. In this example, the train network includes two wagons or train parts W1 and W2 are coupled to each other, ie the train parts W1 and W2 can communicate with each other via the train network 3. In normal operation, the higher-level control unit 4 controls the subsystem control devices 1a, 1b, ..., 1f via the train network in such a way that they communicate with their subsystem components (mechanics/electromechanics) 2a, 2b, ..., 2f, as it is is required to ensure their functions in normal operation. The communication between the superordinate control unit 4, the subsystem control units 1a, 1b, . . . 1f and the subsystem components 2a, 2b, .

Fig. 2 zeigt das Zugnetzwerk 3, in dem das erfindungsgemäße Verfahren zur Diagnose von Subsystemen angewendet wird. Die Subsystem-Steuergeräte 1a, 1b, 1c sind in den Testsignal-Umsetzungsmodus versetzt. Die von der übergeordneten Steuereinheit 4 vorgegebenen Testsignale werden von den Subsystem-Steuergeräten 1a, 1b, 1c umgesetzt. Rückmeldungen der Subsystem-Komponenten 2a, 2b, 2c werden über die Subsystem-Steuergeräte 1a, 1b, 1c ebenfalls umgesetzt und als Testsignalantwort über das Zugnetzwerk 3 an die übergeordnete Steuereinheit 4 weitergeleitet, wo eine Auswertung stattfindet. 2 shows the train network 3 in which the method according to the invention for diagnosing subsystems is applied. The subsystem control devices 1a, 1b, 1c are placed in the test signal conversion mode. The test signals specified by the superordinate control unit 4 are converted by the subsystem control units 1a, 1b, 1c. Feedback from the subsystem components 2a, 2b, 2c is also implemented via the subsystem control devices 1a, 1b, 1c and forwarded as a test signal response via the train network 3 to the higher-level control unit 4, where an evaluation takes place.

Die Kommunikation zwischen der übergeordneten Steuereinheit 4, den Subsystem-Steuergeräten 1a, 1b, 1c und der Rückmeldungen der Subsystem-Komponenten 2a, 2b, 2c ist anhand von gestrichelten Pfeilen dargestellt.The communication between the higher-level control unit 4, the subsystem control units 1a, 1b, 1c and the feedback from the subsystem components 2a, 2b, 2c is represented by dashed arrows.

Fig. 3 zeigt einen relevanten Ausschnitt eines beispielhaften Zugnetzwerks 3, in dem das erfindungsgemäße Verfahren zur Diagnose von Subsystemen verwendet wird. Die Subsystem-Steuergeräte 1a, 1b, 1c sind in einen Testsignal-Umsetzungsmodus versetzt, in dem sie die von der übergeordneten Steuereinheit 4 vorgegebenen und über das Zugnetzwerk 3 übertragenen Testsignale umsetzen. Im Unterschied zum Beispiel in Figur 2 werden hier Komponenten 2a, 2b, 2c von mehreren der Subsysteme getestet, die untereinander Wechselwirkungen aufweisen. Die übergeordnete Steuereinheit 4 gibt die Testsignale vor, welche über das Zugnetzwerk 3 und die beiden Subsystem-Steuergeräte 1a, 1b an die beiden Magnetventilen MV1, MV2 ausgegeben werden. Diese Magnetventile MV1, MV2 dienen zur Steuerung des gezeigten pneumatischen Systems. Die Schaltvorgänge der Magnetventile MV1 und MV2 lassen sich durch einen Drucksensor DS beobachten, der einem weiteren Subsystem-Steuergerät 1c zugeordnet ist. Die Rückmeldung des Drucksensors DS wird nun vom Subsystem-Steuergerät 1c über das Zugnetzwerk 3 als die Testsignalantwort an die übergeordnete Steuereinheit 4 umgesetzt, wo die an die Magnetventile MV1 und MV2 vorgegebenen Testsignale in Bezug gesetzt werden zu der Testsignalantwort des Drucksensors DS. 3 shows a relevant section of an exemplary train network 3 in which the method according to the invention for diagnosing subsystems is used. The subsystem control units 1a, 1b, 1c are placed in a test signal conversion mode in which they convert the test signals specified by the higher-level control unit 4 and transmitted via the train network 3. In contrast to the example in figure 2 Components 2a, 2b, 2c of several of the subsystems that interact with one another are tested here. The higher-level control unit 4 specifies the test signals, which are output to the two solenoid valves MV1, MV2 via the train network 3 and the two subsystem control units 1a, 1b. These solenoid valves MV1, MV2 are used to control the pneumatic system shown. The switching operations of the solenoid valves MV1 and MV2 observed by a pressure sensor DS, which is assigned to a further subsystem control device 1c. The feedback from the pressure sensor DS is now implemented by the subsystem control unit 1c via the train network 3 as the test signal response to the higher-level control unit 4, where the test signals specified to the solenoid valves MV1 and MV2 are related to the test signal response from the pressure sensor DS.

Ein derartiges "in Bezug setzen" kann wie folgt anschaulich erklärt werden: Beim Beaufschlagen der beiden Magnetventile MV1, MV2 mit einem Testsignal (z.B. einer elektrischen Spannung) erwartet die übergeordnete Steuereinheit 4 eine zu den Testsignalen korrespondierende Testsignalantwort. Der Drucksensor DS liefert die reale Rückmeldung des Systems bzw. seiner Komponenten 2a, 2b, 2c in Form von Signalantworten, die die übergeordnete Steuereinheit 4 von dem Subsystem-Steuergerät 1c empfängt. Sofern die reale Testsignalantwort nicht der erwarteten Testsignalantwort entspricht, kann dies ein Hinweis auf ein technisches Problem sein. Eine weitere Diagnose, die nicht auf ein Subsystem beschränkt ist, wird nun dadurch ermöglicht, dass die übergeordnete Steuereinheit 4 verschiedene Testsignale vorgibt, und diese mit den entsprechenden Testsignalantworten in Bezug setzt.Such "putting in relation" can be clearly explained as follows: When a test signal (e.g. an electrical voltage) is applied to the two solenoid valves MV1, MV2, the higher-level control unit 4 expects a test signal response corresponding to the test signals. The pressure sensor DS delivers the real feedback from the system or its components 2a, 2b, 2c in the form of signal responses, which the superordinate control unit 4 receives from the subsystem control device 1c. If the real test signal response does not correspond to the expected test signal response, this can be an indication of a technical problem. A further diagnosis, which is not limited to a subsystem, is made possible by the fact that the higher-level control unit 4 specifies various test signals and relates them to the corresponding test signal responses.

In diesem Beispiel kann die Funktion der Magnetventile MV1, MV2 nicht direkt über Testsignale bzw. Testsignalantworten ermittelt werden, weil z.B. die Magnetventile MV1, MV2 nicht über die Möglichkeit verfügen, direkt über ihren Status Auskunft zu geben. Der Zustand der Magnetventile MV1 und MV2 wird also indirekt über eine Wechselwirkung mit dem weiteren Subsystem ausgewertet, in dem die Signalantworten des weiteren Subsystems ausgewertet werden.In this example, the function of the solenoid valves MV1, MV2 cannot be determined directly via test signals or test signal responses because, for example, the solenoid valves MV1, MV2 are not able to provide information directly about their status. The state of the magnetic valves MV1 and MV2 is therefore evaluated indirectly via an interaction with the further subsystem, in which the signal responses of the further subsystem are evaluated.

Die beschriebenen Beispiele dienen lediglich der Veranschaulichung. Die Anzahl von miteinander verbundenen Systemen sowie die Komplexität des Gesamtsystems werden in der Praxis größer ausfallen.The examples described are for illustrative purposes only. The number of interconnected systems and the complexity of the overall system will be greater in practice.
