Abstract

The invention relates to an arrangement for the transmission of process data, having a rail vehicle (SFZ) and a control entity referred to as landside (LS). The rail vehicle (SFZ) has sensors (SEN1, SEN2), a controller (STG) and a diagnostics server (DIAGS). Sensor measured values determined on the rail vehicle are transmitted to the controller (STG) as process data. The controller (STG) has a configurable data processing system (DATV-STG) to prepare process data of a selected sensor (SEN1, SEN2) for transmission to the diagnostics server (DIAGS). The controller (STG) is connected to the diagnostics server (DIAGS) via a configurable connection (VERB-STG-DIAGS) for the purpose of process data transmission. This connection has bus-linked transmission options (Eth, CAN, MVB), one of which can be selected during the configuration. The diagnostics server (DIAGS) has a configurable data repository (DATH-DIAGS) and a configurable data processing system (DATV-DIAGS). Read-in process data is processed on the basis of functions (F1, F2, CONT) by these configurations. The process data processed in this way then reaches the landside (LS). The rail vehicle configurations can be adjusted from the landside (LS).

Description

[0001] The invention relates to an arrangement for the transmission of process data between a rail vehicle and a stationary control point, referred to as the landside.

[0002] It is known to transmit process data between the rail vehicle and the control point.

[0003] The process data is collected, for example, using sensors on the rail vehicle and evaluated on the land side.

[0004] For example, the sensors include: incremental encoders intended for calculating the speed of the rail vehicle, sensors with analog inputs used for detecting voltages, currents or temperatures, etc., or sensors with digital inputs used for detecting switching cycles of components, etc.

[0005] The process data is determined, processed and transmitted by the rail vehicle using dedicated software that is subject to software approval.

[0006] A change in the process data to be transmitted necessitates a change in the software, which in turn requires a new approval process that is time-consuming and costly.

[0007] This newly approved software then has to be installed on the associated rail vehicles, which is time-consuming and expensive.

[0008] From the document "EKE - Technology for smarter trains", June 12, 2019, pages 1-68, XP055669843, a train control system or train management system is known in which communication systems and safety systems (such as PIS / PA, HMI, GPS, event storage, 3G / WIFI and CCTV) are integrated.

[0009] Applications for the SINAMICS converter family are known from the document "SINAMICS S120 Communication", Siemens AG, October 31, 2019, pages 1-246, XP007022849.

[0010] The object of the present invention is to provide an arrangement for the transmission of process data between a rail vehicle and a stationary control point, which enables changes to process data without requiring a new approval of the corresponding software.

[0011] This problem is solved by the features of claim 1. Advantageous further developments are specified in the dependent claims.

[0012] The arrangement according to the invention for transmitting process data comprises a rail vehicle and a stationary control point, designated as the landside. These are interconnected for the transmission of process data from the rail vehicle to the landside.

[0013] The rail vehicle is equipped with sensors, a control unit, and a diagnostic server. Each sensor is connected to the control unit, so that sensor readings acquired by the rail vehicle are transmitted to the control unit as process data.

[0014] The control unit features configurable data processing, whereby process data from a selected sensor is collected, pre-processed, and prepared for transmission to the diagnostic server. The control unit is connected to the diagnostic server via a configurable connection, through which the process data is transmitted from the control unit to the diagnostic server.

[0015] This configurable connection has a number of bus-bound transmission options (Ethernet, CAN, MVB), from which a predetermined bus-bound transmission can be selected via configuration to transfer the process data from the control unit to the diagnostic server.

[0016] The diagnostic server features a configurable data storage system that prepares incoming process data from the bus-based transmission for function-based processing by the diagnostic server. For this function-based processing of the process data, the diagnostic server includes a configurable data processing module connected to the data storage system. This module provides several selectable functions for processing the process data, from which a predefined function can be selected through configuration.

[0017] The configurable data processing system is connected to the landside via a configurable link to transfer the process data processed via the selectable function to the landside. The rail vehicle-side configurations can be adjusted from the landside.

[0018] In an advantageous further training, the configurable connection between the control unit and the diagnostic server is designed for Ethernet transmission, CAN transmission or MVB transmission of the process data.

[0019] In an advantageous further development, the configurable data processing of the control system allows for the setting of value range normalization, a sampling time interval and / or a sensor selection for the process data provided by the sensors.

[0020] An additional function can be created on the land side through advantageous further training. This additional function can be implemented there via the configurable data processing of the diagnostic server.

[0021] With regard to the prior art, the present invention has the significant advantage that properties and parameters of functions can be changed or extended during the operation of the rail vehicle without requiring a new approval of the necessary software.

[0022] The present invention makes it possible to operate the rail vehicle with additional or modified functions, even for a limited time.

[0023] The present invention has the further significant advantage that process data can be changed or expanded on the rail vehicle during its operation without requiring renewed approval of the necessary software.

[0024] The present invention enables the subsequent installation or extension of sensor technology provided on the rail vehicle.

[0025] The present invention thus enables a rapid response to requirements from fleet management, engineering and changes in the system design of the rail vehicle.

[0026] The present invention enables adaptable fault finding in rail vehicles and / or adaptable evaluation of fleet data or data from the rail vehicle. The invention is explained in more detail below with reference to a drawing. The drawing shows: FIG 1 the present invention in an overview view, FIG 2 with reference to FIG 1 the present invention in a more detailed further illustration, and FIG 3 with reference to the figures FIG 1 and FIG 2 a representation of the so-called "container".

[0027] FIG 1 The present invention is shown in an overview representation in which selected elements described below are configurable for process data transmission.

[0028] The configuration enables, according to the invention, that process data transmitted during the operation of a rail vehicle (SFZ) can be changed, supplemented and, if necessary, (pre-)processed and transferred to a land-based system (LS).

[0029] The rail vehicle SFZ has a sensor SEN, a control unit STG and a diagnostic server DIAGS.

[0030] With the help of the SEN sensor, measured values ​​are recorded or determined as process data and transferred to the STG control unit.

[0031] The control unit (STG) is responsible for collecting process data from several sensors and, if necessary, processing this data in advance for further use.

[0032] For this purpose, the control unit STG has a data processing function DATV-STG, which can be changed via a configuration CONFIG-STG.

[0033] The control unit (STG) is connected to the diagnostic server (DIAGS) via a configurable connection VERB-STG-DIAGS. This configurable connection allows for the modifiable forwarding of process data from the control unit (STG) to the diagnostic server (DIAGS).

[0034] The diagnostic server DIAGS is responsible for collecting, storing, and processing transmitted process data, as well as making the result of this processing available for transmission to the landside LS or preparing it for this transmission.

[0035] For this purpose, the diagnostic server DIAGS has a data processing unit DATV-DIAGS and a data storage unit DATH-DIAGS, both of which can be configured via a configuration CONFIG-DIAGS on the part of the diagnostic server DIAGS.

[0036] The diagnostic server DIAGS or the rail vehicle SFZ is connected to the landside LS via a configurable connection VERB-SFZ-LS, which provides functionalities of a fixed control point.

[0037] The landside LS has a result data processing DATV-ERG, which processes the process data transmitted by the rail vehicle SFZ or by the diagnostic server DIAGS.

[0038] The DATV-ERG results data processing system evaluates the process data, for example, by displaying a process diagram or calculating the maintenance requirements of components. Further applications include troubleshooting based on the process data or long-term analysis of the process data.

[0039] In summary, the present invention provides a configuration via the landside LS: the data processing DATV-STG of the control unit STG, the connection VERB-STG-DIAGS between the control unit STG and the diagnostic server DIAGS, the data processing DATV-DIAGS and the data storage DATH-DIAGS of the diagnostic server DIAGS, the connection VERB-SFZ-LS between the rail vehicle SFZ or between the data processing DATV-DIAGS and the landside LS.

[0040] For this configuration, the landside LS has a configuration unit KONFIG-DIAGS-STG, which creates or provides configuration instructions for the aforementioned elements, which are then transferred from the landside LS to the aforementioned elements for implementation there.

[0041] To transfer new functions from the landside (LS) to the rail vehicle (SFZ) for implementation in its associated elements, a container called CONT is used. This container is created on the landside and transferred to the rail vehicle (SFZ) and its elements. This process is described in more detail in the following figures.

[0042] FIG 2 shows with reference to FIG 1 the present invention in a more detailed description.

[0043] The SEN sensor from FIG 1 Here, it is configured as an analog sensor SEN1 and a digital sensor SEN2. Both sensors, SEN1 and SEN2, acquire and transmit measurement data as process data to the control unit STG of the rail vehicle SFZ.

[0044] The sensors SEN1, SEN2, for example, detect the speed of the rail vehicle SFZ or detect temperatures of components of the rail vehicle SFZ, etc.

[0045] The process data is transmitted, for example, via a digital-to-analog converter (DAC) to a configurable unit B1, which normalizes the sensor readings and provides them as process data of a specific data type for an output interface B2. The configuration allows settings such as the normalization and / or the data type to be used.

[0046] The output interface B2 is configurable and prepares the process data for transmission via the VERB-STG-DIAGS connection to an interface B3, which is part of the DIAGS diagnostic server.

[0047] The two interfaces B2 and B3 use, as examples, one of three transmission methods provided for this purpose: a transmission via the well-known Ethernet bus Eth, or a transmission via the well-known CAN bus, where CAN stands for "Controller Area Network" and describes a serial bus system, or a transmission via the "Multifunction Vehicle Bus" known from railway technology and referred to as MVB for short.

[0048] The process values ​​are converted into a machine-readable format for transmission from the control unit STG to the diagnostic server DIAGS via the VERB-STG-DIAGS interface and, after successful transmission, are made available to the diagnostic server DIAGS for further processing.

[0049] For data transmission via the VERB-STG-DIAGS interface, the physical interface (Eth, CAN, MVB) used to transmit the process values ​​is specified. The content of the corresponding data transmission telegram is also defined.

[0050] The digital-to-analog converter DAW, unit B1 and output interface B2 form the components shown in the figure. FIG 1 The described and configurable data processing DATV-STG of the control unit STG. These are configurable via a configuration interface KONFIG-SS-STG of the control unit STG.

[0051] The configuration interface KONFIG-SS-STG of the control unit STG receives configuration instructions via the landside LS, as described above.

[0052] The configuration of unit B1 and output interface B2 is carried out via a unit KONFIG-STG-P connected to the configuration interface KONFIG-SS-STG.

[0053] The sensors of the digital-to-analog converter DAW are configured via a unit KONFIG-STG-S connected to the configuration interface KONFIG-SS-STG.

[0054] The connection of the two sensors SEN1, SEN2 to the digital-to-analog converter DAW, as well as the properties or operation of the elements DAW, B1, B2 of the data processing DATV-STG, are determined via the aforementioned configuration units KONFIG-STG-P and KONFIG-STG-S.

[0055] For example, a value range normalization, a sampling time interval, etc., is set for the process data provided by the sensors. It is also determined which sensor values ​​are transmitted to the DIAGS diagnostic server as process values.

[0056] This makes it possible to change or adapt the properties of the sensor system formed by the sensors SEN1 and SEN2 during the operation of the rail vehicle.

[0057] Subsequent modification of the sensor technology in the rail vehicle is also possible without having to change or re-approve the software used for process data processing on the rail vehicle.

[0058] The diagnostic server includes an additional configuration interface, KONFIG-SS-DIAGS, which receives its configuration instructions via the landside LS and transmits them to a KONFIG-DIAGS unit.

[0059] The configuration of functions F1, F2 or the container CONT, which provides a further function, is carried out via a unit KONFIG-FUNC connected to the unit KONFIG-DIAGS.

[0060] The functions F1, F2, and the container CONT form the structure shown in the figure. FIG 1 described data processing DATV-DIAGS of the diagnostic server DIAGS.

[0061] The process values ​​of the data storage unit DATH-DIAGS are configured via a unit called KONFIG-DATH, which is connected to the unit KONFIG-DIAGS.

[0062] The DATH-DIAGS data storage unit uses the KONFIG-DATH unit to determine which process data is read and processed by which transmission method (Eth, CAN, MVB).

[0063] These selected process values ​​are then made available in the DATH-DIAGS data storage of the DIAGS diagnostic server to the associated functions F1, F2 or the function of the CONT container.

[0064] The following is an example scenario for the functions F1, F2 and CONT that will be executed: The properties of the functions F1 and F2 differ in their basic characteristics; for example, both are designed as cyclic recording functions or as histogram functions.

[0065] The result of the functions F1, F2 is stored as a respective file in a respective file system AF1, AF2 and transferred via this to the land side LS.

[0066] If not all basic properties of required functions are known when creating the software for the diagnostic server DIAGS, another function is provided in the container CONT from the landside LS during the operation of the rail vehicle and transferred to the diagnostic server DIAGS.

[0067] When the diagnostic server DIAGS is restarted, the function contained in the container CONT is activated by the diagnostic server DIAGS and executed as an additional function. The result of this function is stored as a file in a filesystem AF3 and then transferred to the landside LS.

[0068] The transfer of files from the file systems AF1, AF2, AF3 is carried out via the method shown in Figure FIG 1 known interface VERB-SFZ-LS.

[0069] The configuration instructions provided by the landside LS are preferably transmitted wirelessly from the landside LS to the rail vehicle SFZ - in this case, the interfaces KONFIG-SS-DIAGS and KONFIG-SS-STG are designed to carry out the wireless transmission.

[0070] FIG 3 shows with reference to the characters FIG 1 and FIG 2 A representation of the CONT container.

[0071] To make the behavior of functions F1, F2 and CONT configurable, they have the following structure: Each function has a configurable input interface IN and a configurable output interface OUT.

[0072] Process data is transmitted to the respective function for processing via the configurable input interface IN.

[0073] Process data from the respective function is made available for subsequent processing via the configurable output interface OUT.

[0074] The function receives the necessary configuration instructions for the process data to be processed or the required parameters via a configuration interface KONFIG.

[0075] The configuration of the two interfaces IN and OUT is also done via the configuration interface KONFIG.

[0076] The function's operational behavior is controlled via an action interface (ACT). Possible action commands include, for example, "Start the function," "Apply a new configuration," "End the function," etc.
