Definitions

  • the present invention relates to a method for paperless commissioning of a control unit, in particular a MiniLEU S11, a LEU S21 and a MSTT signal, for a train protection component, in particular an ETCS balise, a signal, a switch.
  • a control unit in particular a MiniLEU S11, a LEU S21 and a MSTT signal
  • a train protection component in particular an ETCS balise, a signal, a switch.
  • ETCS European Train Control System
  • the corresponding train control units such as ETCS balises, signals, level crossings, axle counters and switches, and their associated control units, such as offered by Siemens AG under the names MiniLEU S11, LEU S21 and MSTT Signal, to be installed in the lines and programmed according to the configuration with the corresponding control data.
  • MiniLEU S11, LEU S21 and MSTT Signal offered by Siemens AG under the names MiniLEU S11, LEU S21 and MSTT Signal
  • the present invention is therefore based on the object of specifying a method for the paperless commissioning of a control unit for a train control component, which facilitates the commissioning of commissioning while at the same time maintaining the required safety level according to SIL4.
  • the control unit is also regarded synonymously as the target system.
  • the commissioning staff is only once again requested, within the scope of the provided second test protocol, to confirm the agreement of the calculated checksums with the encrypted setpoints for the checksums.
  • the first test protocol can be displayed in very simple form on the programming tool, eg "Checksum comparison OKAY".
  • the second test protocol is transmitted from the programming tool to a database and archived in the database.
  • a particularly advantageous embodiment of the present method can be achieved if the encrypted setpoint values for the checksums are transmitted to the programming tool in a non-machine readable and evaluable manner. In this way, it is ensured that the calculated actual checksum is actually determined by the control unit was erroneously output the encoded setpoint values for the checksums as actual values in the programming tool and not via any error whatsoever.
  • This procedure is particularly relevant because the control data and the control units implemented with it must correspond to the highest level of safety in the railway sector, SIL4, although the programming tool used and the software for the configuration of the control unit do not have to fulfill any safety level in the sense of a SIL level.
  • the encrypted setpoint values for the checksums are transmitted in the form of an integrated image.
  • Such images are neither electronically nor readable for the programming tool.
  • the second test protocol in the form of a vector-based page description language, preferably in pdf format, created.
  • the figure shows schematically the procedure of the method for paperless start-up of a waypoint, such as, e.g. a transparent data ETCS balise as Switzerlandbeein Letungsech with its associated control unit 20 - also called target system.
  • a waypoint such as, e.g. a transparent data ETCS balise as Switzerlandbeein Letungsappel with its associated control unit 20 - also called target system.
  • a configuration tool 10 provides examination-relevant data for a programming tool 12.
  • the project planning tool 10 can, for example, a An interlocking system or a control system from which it receives the relevant test-relevant data. Alternatively, however, the project planning tool 10 can also be trained so that the test-relevant data can be generated with this tool.
  • control data 14 for the train control unit also referred to as target system
  • a template 16 for a second test protocol and encrypted set values 18 of checksums for checking the correct loading of the control data 14 onto the control unit 20 are included in the test-relevant data.
  • control unit 20 is programmed by the programming tool 12 with the control data 14 provided by the configuration tool 10.
  • the commissioning staff may be made for the commissioning staff to connect the programming tool 12, wired or wirelessly, to the control unit 20 on site and transmit the data via the corresponding interface.
  • control unit 20 now calculates actual checksums 22 for the programmed control data 14 on the control unit 20 using a key 24 unknown to the programming tool 12. In this way, with the required security level of SIL4, it is ensured that the non-secure programming tool 12 is not in is able to determine the correct actual examination sums 22 themselves.
  • the actual test sums calculated by the control unit 20 (it may also be a single checksum) are then transferred to the programming tool 12.
  • the programming tool 12 assembles a first test protocol 28 by automatically comparing the determined actual checksums 22 with the set values 18 for the checksums.
  • SIL4 is that the programming tool 12, the setpoints 18 never in plain text (in the sense of machine readable and evaluable) has available, but by a predetermined combination of the determined by the control unit 20 IST checksums 22 with the supplied by the configuration tool and with the programming tool 12 not known key 26 encrypted setpoint values 18 for the checksums in the case of a correct programming of the control unit 20 comes to a predefined constant value. The test is completed when this predefined constant value has been reached.
  • a fifth step 5 the calculated checksums 22 and the encrypted checksum setpoints 18 are displayed on the commissioning / review tool 29 programming tool 12. This can also be done, for example, only in the simplified form that the programmer displays "Checksum (s) OK".
  • the setpoint values 18 for the checksums have been supplied by the configuration tool 10 to the programming tool 12 in such a way that the setpoint values 18 can not be read and evaluated directly by machine, but nevertheless can be displayed for the commissioning personnel, e.g. in the form of an integrated picture.
  • the commissioning staff then has to acknowledge this second test protocol, whereby in the present exemplary embodiment there is only an indication of the second test protocol if the correspondence between the calculated checksums 22 and the encrypted set values 18 for the checksums is given.
  • the name 30 of the acknowledging tester is also deposited with reference to the second test protocol.
  • the programming tool 12 creates a second test protocol 32 in the form of a pdf file, with reference to the already transmitted template 16, adding the identity / name 30 of the tester and the calculated checksums 22 and encrypted setpoints 18 for the checksums.
  • a special method is used to ensure that the desired checksum 18 contained in the second test protocol 32 can not be used directly by the non-secure programming tool 12.
  • the set checksum 18 can therefore be provided, for example, as an image that can not be read and evaluated directly by machine.
  • the generation of the pdf file for the second test protocol 32 can therefore be implemented on the programming tool 12 as a separate process that is executed in isolation from the rest of the data processing.
  • the generated second test protocol 32 can optionally also be signed with an electronic signature.
  • the second test protocol 32 is transmitted in this step by the programming tool 12 to a database 36 and archived there.
