Definitions

  • the invention relates to a method for the reliable determination of a current output information in the field of railway technology after failure of a client device connected to at least one sensor device via a network with an evaluation unit.
  • Client devices are used in train operation to determine output information based on input information previously detected by one or more sensor devices.
  • the client device comprises an evaluation unit for receiving and processing the input information.
  • the client device can also process internal state information.
  • An improvement in this regard is the in EP 1 498 336 B1 described method for determining the occupancy state of a track section, in which after a restart of an axle counting system (client device) synchronized counts (input information) and status information (output information) are stored in the points of delivery. After a restart of the axle counting system, this stored information is transmitted to the evaluation unit together with the current count values. If the difference of the stored values equals the difference of the current values, the track section is considered free.
  • a disadvantage of this method is that it is defined only for determination of occupancy states.
  • the storage locations are external components whose connection and storage costs are very high.
  • the object of the invention is to propose a method with which a reliable determination of output information in the field of railway technology, which is derived from detected input information, can be ensured even in the event of failure of the state and output information determining client device, the method applicable to different railway engineering areas should be.
  • the method steps a) to d) are repeated for different reference times and a continuity test is carried out with regard to a continuous operation of the sensor device.
  • the method steps a) to d) are carried out repeatedly, so that Einhol seeds be stored at different reference times in the sensor device and can be retrieved from the client device, wherein at least the most recent stored Einholinformation remains stored in the sensor device.
  • a regular transmission of the input information from the sensor device to the client device is provided.
  • the continuity check is independent of failures from the client device.
  • the current output information is determined on the basis of the last stored data record and on the basis of the transferred inbound information which was determined during the failure of the client device and was transmitted to the client device as wake-up information after reactivation of the client device.
  • the task of the client device is to determine output information based on input information.
  • the input information comprises data which are determined by the sensor device.
  • the storage device is part of the network and may be connected to the client device or part of the client device.
  • the memory device is independent of the operating state of the client device, ie if the client device fails (eg due to a crash or shutdown), the data stored in the memory device is not lost.
  • an internal state information eg the number of axes within a track section
  • the output information eg occupancy state of the track section
  • Output information is information obtained from input information from the client device. Output information may be obtained directly from the input information transmitted from the client device or together with internal state information that previously determined from the transmitted input information has been. However, the input information and internal state information used to determine output information must refer to the same point in time. A current state or output information is that state or output information which was determined on the basis of last-determined input information. Output information is output from the client device for processing by other devices. The output information corresponds in many cases to the state information, but may also be information derived from the state information (eg, occupancy states derived from the number of axles within a track section).
  • the fetch information comprises a selection of the data of the input information.
  • the selection is defined so that the Einhol seeds that have been archived since the reference time, make it possible at any time, upon reactivation of the client device to determine the current state information of the client device based on the last stored record again.
  • the catching information stored in the sensor device can (but does not have to) include all the data of the determined input information. For example, in the case of a cyclically determining point of delivery, only those count states in which the count state has changed must be archived.
  • the retrieve information transmitted after reactivation of the client device comprises, in particular, those retrieve information that was determined and stored during the failure of the client device and therefore could not be transmitted to the client device and / or processed by the client device before the client device was reactivated. If no input information was detected in the period between failure and reactivation of the client device, the information is transmitted that nothing has changed during the failure of the client device.
  • the retrieval information stored in the sensor device is related to a reference time and includes a corresponding time mark.
  • the stored data set comprises the input information determined at a specific time and the state information and / or output information determined therefrom, which are stored in the memory device.
  • the stored data record is characterized in that its data components are reliably consistent, ie the input information and the output information or state information determined therefrom describe field states at the same time T archiving .
  • a special variant of the method according to the invention provides that the data record for storage is transmitted from the client device to the storage device via the network.
  • an external memory is used as memory device as memory device, which is connected by the network with the client device.
  • the network may include a sensor network and a system network, wherein the system network connects the client device to the storage device and the sensor network connects the sensor device to the client device.
  • the sensor network is used to transmit the input information and possibly of re-request messages, confirmation messages and continuity information.
  • the system network typically (but not necessarily) has greater bandwidth and / or computing capacity than the sensor network.
  • the storage device is then integrated in the client device.
  • the storage device must then be a non-volatile memory, i. a memory in which the contents remain stored at least until the client device is reactivated.
  • a continuity information is determined during reactivation and transmitted together with the collection information.
  • the continuity information indicates whether the sensor device has been in safe operation since the last time it was archived. This ensures that the data used to determine the output information after the client device fails is complete. If the continuity information does not contain confirmation of continuity or if continuity information is not provided, the stored dataset may be incomplete or erroneous. If the record is incomplete or incorrect, the client device can update the current one Not sure to determine output information. The system must then be reinitialized using methods other than those described in this patent.
  • all catch-up information stored between failure and reactivation of the client device is transmitted from the sensor device to the client device.
  • this variant is not optimized in view of the storage capacity requirement, it is particularly easy to develop because it enables the same process steps for determining the current output information as in normal operation for determining the output information during the reactivation.
  • the sensor device receives a confirmation message after a data record has been archived-be it directly from the memory device or indirectly from the client device.
  • the confirmation message which is assigned to the reference time concerned, it can be reconstructed by the sensor device that the input information was already processed before the reference time and has flowed into the already archived state information.
  • the sensor device knows that the collection information, which was stored before the reference time, is no longer needed for future reactivations and thus the corresponding storage space can be released.
  • the size of the memory for the collection information and the associated costs can be limited.
  • the corresponding input information can be classified as "not transmitted” and can then (after) be transferred after reactivation of the client device as Einholinformation.
  • the sensor device retains its entire history in a ring buffer and overwrites the oldest elements if no more storage space is available.
  • the ring buffer can be pre-sized to allow a failure of the client device to ring buffer not crowded.
  • the memory requirement can also be limited. In this case no confirmation message is necessary.
  • the client device After reactivation of the client device, the client device preferably transmits a new request to the sensor device, which triggers the transmission of the collection information.
  • the transmission of the continuity information is preferably also triggered by the new request.
  • count values are determined as input information. Based on the counts, the occupancy state of a track section is determined as output information.
  • the occupancy state of a track section is determined as output information.
