Definitions
- the invention relates to a method for providing a diagnostic message, the at least one process in a
- Rail vehicle is assigned, in which the process is performed by at least one device of the rail vehicle, generates a process associated diagnostic device of the rail vehicle at least one diagnostic message and at least one environment data set is detected by a data acquisition device.
- the generation of automatic diagnostic messages is now playing an increasing role in the operation and maintenance of a fleet of rail vehicles.
- Most control processes at least one diagnostic device is assigned, which has the function to generate when certain events occur corresponding predefined diagnostic messages. It also captures environmental data that serves to extend the information content provided by diagnostic messages. This is required, for example, in standards UIC 557 and VDV 166.
- the creation of messages which are directed ter to the vehicle operator, the train conductor or to a Riversidemitarbei- is carried, typically by the Verknüp ⁇ Fung individual diagnostic messages with the environment data, the entire information content to reconstruct a comprehensible from the target individual process flow is analyzed.
- environmental data may include detected speed, deceleration, temperature, position, pressure, current and / or voltage characteristics, for example for determining a current operating state of the rail vehicle or a device thereof, in particular the at least one device for Execution of at least one sub-process corresponds to the process serve.
- the invention has for its object to provide a generic method for producing a diagnostic message in which the information density can be increased and the processing effort can still be kept low.
- the data acquisition device has at least one picture and / or sound-recording unit on ⁇ , wherein video and / or audio data from the video and / or sound-recording unit are recorded and the environment data set includes the image and / or sound data and the Diagnosemel ⁇ tion and the environment data set to form the diagnosis message are aggregated by an aggregation unit of the rail vehicle.
- the required for the preparation of the information content and the formation of diagnostic ⁇ message overhead can be kept Hin ⁇ view low in at least two.
- a processing of the information in the vicinity of the data sources on the other hand the advantage of a ört ⁇ union context of the data with one another, which produce at a treatment at a remote location, at a later time and / or as part of a substantial amount of Ge ⁇ collected information initially is.
- the diagnosis message can be transmitted after a short time to a target person, who accordingly can quickly take a measure in connection with an event that has occurred.
- the image and / or sound data are advantageously recorded during the process. Since video and / or audio data have a high information density, a particularly high volume of data can be generated which is processed advantageously locally in the rail vehicle, together with the corresponding Wenig ⁇ least a diagnostic message. Image and / or sound data require a particularly high bandwidth in a data transmission, which may not be present in a communication of the rail vehicle with the land side.
- the picture and / or sound-recording unit may be formed as a camera, Videokame ⁇ ra and / or microphone.
- the device is for carrying out at least a partial process of the process, in particular, it may be provided for carrying out the entire process. It may be a hardware technical actuator unit, in particular a Antriebsein ⁇ standardized for performing operating steps and / or at least one control unit, the at least one such
- Actuator unit is associated and / or have a computing unit that executes a software control process.
- a diagnostic message is in particular a message that is selected in a set of predefined or preformulated short messages.
- This set which is preferably associated with the process, is associated with a set of predefined events that can potentially occur at the expiration of the corresponding process. In this sentence, each message is therefore expediently associated with at least one of these predefined events in the process flow.
- the definition of a set of diagnostic messages depends on the particular process.
- Predefined diagnostic messages preferably have a predefined format.
- the diagnostic messages contain information content that is essentially limited to the designation of an event that has occurred. The diagnostic message can only designate the event, but it is advantageous if the diagnostic message means and an event occurred to this device.
- Typical formulations are eg "device A reports a defect", “device B has responded”, “device C reports successful completion of process X”, etc.
- a diagnostic message is therefore preferably given the occurrence of a predetermined event by the diagnostic device or by a control unit thereof, for example generated by a Prozes ⁇ sorappel.
- environment data is preferably data that is acquired by the data acquisition means.
- the diagnostic device and data collection device are preferably different entities.
- the environment data are suitably adapted, together with one or more diagnostic messages
- "environment data” can be understood as environmental data within the meaning of standard UIC 557 and / or VDV 166.
- An "aggregation" of a diagnosis message with at least the environment data rate, in particular the formation of a data burst is intended, at least from this data understood ⁇ the which is one suitable for forming understandable to a target person, for example, visual and / or acoustic diagnostic message.
- A is diagnostic message expediently formed on the basis of the aggregation of the at least one diagnostic message with the environment data set. It is used, a comprehensible from a target person information on the operation of the process, in particular the circum stances ⁇ de, preferably the cause of a specific event in the process sequence which is signaled by the diagnostic message to provide.
- the aggregation of the at least one diagnostic message and the environment data record be followed by the acquisition of the environment data record.
- the process involves bringing together the information from the various data sources, saving time and processing time.
- the gensets can ⁇ yaw directly and / or directly be executed after detecting the setting record. It is furthermore conceivable that the aggregation is already triggered during the acquisition of the environment data record.
- the acquisition of the environment data record by the data acquisition device preferably depends on the generation of the at least one diagnostic message.
- the generation of a diagnostic message can advantageously trigger a detection process of environmental data. If a diagnostic message relating to a device of the rail vehicle is generated, then a detection process of data relating to the environment of the device and / or parameters that are relevant for the operation of the device can be triggered in a targeted manner.
- the environment data record assigned to a device has a higher information content than a diagnostic message relating to this device. As a result, a large volume of data can be generated during the course of a process, which can be attributed to the collection of environment data records.
- the data acquisition device is a land-solid device.
- the image and / or sound recording ⁇ taking unit may be constituted by a fixed base at a platform, wherein recorded on that platform for a stay of the rails ⁇ vehicle data to a unit of the rail vehicle, in particular directly to Aggrega ⁇ tion unit can be transmitted ,
