Definitions
- the present invention relates to a method according to the preamble of patent claim 1.
- DE-PS 32 32 308 possible component failures that can lead to changes in transmitted data, recognized by the transmission and comparison of non-equivalent data words. However, this leads to one additional effort without a comprehensive security check.
- EP 0 683 082 A1 also describes a device in which the operator of a control system is largely relieved of monitoring tasks. Thereby already set Switching state combinations read out by a display device and in terms of compatibility checked with logical rules stored in a data processing system. This logical Rules must be created when planning a signal box and checked for correctness. To ensure comprehensive security, therefore, must be done with great effort for everyone switching conditions that may occur error-free logical rules are provided.
- the present invention is therefore based on the object of a method for the control and To specify the monitoring of a traffic control system having actuating and monitoring elements, through which, taking into account high safety requirements, at least two lanes for track-bound vehicles can be set with little effort.
- the method according to the invention allows simple engineering of traffic engineering systems, in particular of electronic signal boxes in railway technology. By using two mutually independent procedures for control and monitoring arise simultaneously less effort for project planning of the plant as well as increased operational safety.
- all of the control elements belonging to this route are a control process versus other requests to build further routes and Operations locked and then posed, with each being performed by the control process Changes to the positions or states of the control elements only after a successful check for admissibility by means of an inspection process that is independent of the control process.
- the control process can therefore with less effort can be realized because the security certificate based on a diversified review the admissibility of changes in the positions or states of the control elements by a dated Control process independent test process is carried out.
- the control process preferably works in accordance with the known closure panel principle.
- the required dependencies of the route elements involved in the individual routes are documented in a matrix in a locking plan or in a locking table. This form of documentation justifies the designations of logic that are also used as a locking plan principle or a tabular principle.
- the individual guideway elements involved are wired in free connection and do not correspond to the track topology.
- the advantages lie in the flexible adaptability for application-specific functionalities.
- a control process that works according to the locking board principle can be easily configured by creating a table in which the positions and states of the control elements provided for the individual travel routes are entered. The routes can therefore be switched easily, which eliminates the need to search for a route using the track plan principle with the problems described above.
- the monitoring of the opening and closing caused by the control process according to the closure panel principle if necessary, the removal of the route is also carried out by the test process in this case after Principle of the track plan by checking on a case-by-case basis whether the actuating and / or Monitoring elements are used for an already created route and thus already are locked.
- the testing process is advantageously carried out according to the track plan principle, through which all positions and conditions the actuators blocked for other routes are taken into account.
- the layers to be switched and states are therefore not based on a large number of logical rules created in advance, but checked based on the actual condition of the entire system. Through this comprehensive Testing results in increased operational reliability.
- the review is carried out after Track plan principle with little effort, since the correct one associated with a high effort and complete creation of test rules for route setting is no longer necessary.
- the test process which is independent of the control process, is based on the locking panel principle realized.
- the measures according to the invention therefore make it possible to adapt them to a planned one Track topology and a required level of security, one on two independent from each other To implement process-based system control with the least possible effort.
- the tax process is preferred for smaller systems according to the closure panel principle and for larger systems Systems implemented according to the track plan principle. Larger expenses for the implementation of the tax process do not apply, however, because the required security verification by the application of the control process independent test process can be fulfilled more easily.
- Fig. 1 shows a railway system with two tracks running in parallel from A to B or from C to D.
- GL1, GL2, the two connecting tracks GL12, GL21 and two each to this connecting track Turnouts W1, W3 or W4, W2 connecting GL12, GL21 can be connected to one another.
- the tracks GL1, GL2 are divided into different areas, which are monitored by Freemeldemem FM1, ..., FM14.
- the track areas around the turnouts W1, ..., W4 to the middle of the associated connecting track GL12, GL21 are monitored by FM3, FM5, FM10 and FM12.
- the areas belonging to the free detectors FM1, FM7, FM8 and FM14 are signals S1, S4, S5 and S8 intended.
- the areas associated with the free detectors FM4 and FM11 are the signals S2 and S3 or S6 and S7 assigned.
- track elements S1, ..., S8, W1, ..., W4, FM1, ..., FM14 are in the states specified in Table 1 below.
- This table 1 corresponds to the table described in DE-AS 10 30 383, in which the target loads of all the route elements to be involved in the individual routes are stored.
- the routes 1, ..., 5 can therefore be set using a control process.
- Every change of the positions to be carried out by the control process according to the closure panel principle or states of the control elements is therefore only carried out after a successful check for admissibility an audit process that is independent of the tax process.
- an audit process that is independent of the tax process.
- From the standard EN 50128, section B, 17 or the DE-AS 24 02 875 is known that protection against processing errors can be achieved by all safety-relevant commands are elaborated in two independent ways, with the Operation with only one computer, double command development with two different programs and intermediate command check program is performed by which the commands developed be compared.
- a command is drawn up according to the locking panel principle and an independent one Verification according to the track plan principle.
- the check according to the track plan principle is guaranteed As is well known, a high level of security. Because the route search and process control according to the track plan principle omitted, there is little effort for the configuration and implementation of the test process.
- the monitoring of the opening and closing caused by the control process according to the closure panel principle if necessary, the removal of the route through the test process is based on the track plan principle, by checking on a case-by-case basis whether the actuating and / or monitoring elements to be blocked and provided can be used for a route that has already been created and are therefore blocked.
- the control process and the independent test process can be controlled by software that stored in parallel or separately operated computers or even only in a single computer is.
- the control process as shown in FIG. 1 by a control process computer PR1 and the test process by a test process computer PR2 is controlled.
- the control process computer PR1 has a memory which, among other things, for storing the Lock plate data is used.
- the test process computer PR2 has a memory that i.a. for filing the set travel routes and preferably also for storing the track plan of the monitored Route network serves.
- the control of the control elements and the monitoring of the states of the track elements takes place as in the interlockings known from the prior art.
- route 1 When route 1 is created by the control process, all associated control elements are blocked from other requirements for routes and controls. If route 5 is already set, the states of the track elements associated with route 5 are stored in the test process computer PR2. The control process is able to set the travel routes automatically. To ensure the required security, all control commands generated by the control process according to the locking panel principle are verified element by element in the test process according to the track plan principle on the basis of the actual positions of the control elements and the information provided by the monitoring elements and, taking into account the routes already created, in particular with regard to enemy routes, required side protection is checked and released if no conflicts are found.
- the test process can also be used to determine whether the side protection for the set Route is guaranteed.
- the side protection is by the Switch W1 and the signals S3 and S8 guaranteed.
- the switch W1 is in the "straight" state and the signals S3 and S8 blocked in the "Halt” state.
- the route 3 shown in FIG Edge protection guaranteed by signals S2, S5 and S4.
- the signals S3 and S8 in the state "Halt” blocked.
- the control process can be used to set a route after an order has been placed, e.g. detected whether the elements indicated in the corresponding line of the locking table (table) for other routes are used or reserved or released for switching (the control process therefore does not see a driveway, but the arbitrarily arranged elements of a row of the locking panel).
- the check is based on the track plan principle.
- the one after The test process working on the track plan principle has the data of the track topology at least for any adjustable route. The check can be done with more or less effort. For example, it is only checked whether the changes intended by the tax process are correct Guide the setting of the route. E.g.
- the correct setting is not provided for a turnout, This is due to the control process, which has no knowledge of the topology of the rail network and the routes has not recognized.
- the control process which has no knowledge of the topology of the rail network and the routes has not recognized.
- the fault is easily recognized because the lane between the endpoints is due the wrong position of the switch is interrupted.
- the testing process can include other framework conditions, e.g. Check edge protection, maximum permissible speed, etc.
- the check is preferably carried out, as described in the section above, after the reservation of all elements specified in a line of the locking panel. After successful testing, the driveway set overall. It is also possible to carry out the test before the changeover individual element.
- the test process working according to the track plan principle linked to a parameter list that allows customer-specific settings to be checked, which are carried out by the control process and which are independent of the topology of the to be set Routes are (e.g. for a route that serves express train traffic, a decentralized one arranged signal lamp).
- the signal lamp is therefore an element in the concerned Row of the closure panel and recorded by the test process based on the parameters supervised.
- the control process for small systems becomes simpler according to the closure panel principle and for larger systems it is easier to implement the track plan principle (the test process is implemented accordingly according to the track plan or the locking panel principle).
- the test process is implemented accordingly according to the track plan or the locking panel principle.
- the tax process with no major differences in effort can be realized according to the locking panel principle or according to the track plan principle.
- plants tend to grow and products gradually, with each generation a larger one Should have scope of services.
- the choice of principle for realizing the control process is therefore, taking into account the prevailing framework conditions and the development forecasts made on a case by case basis hold true.
- the scope of services of both processes is considered, taking into account the total to be fulfilled Security requirements, preferably coordinated. For example, can the performance of the Control process in relation to the fulfillment of the security requirements can be reduced if the Scope of services for the testing process is chosen accordingly larger.
- the system structure of both processes is therefore preferably chosen to be modular, so that a corresponding one Adaptation to the overall security requirements can be achieved with little effort can.

Description
Nach dem Spurplanprinzip arbeitende elektronische Stellwerke weisen einen Speicher auf, in dem alle stellbaren Fahrstrassen aufgezeichnet sind. In der DE-AS 10 30 383 (siehe auch DE-PS 35 35 785 C2, Spalte 4, Zeilen 38-47) ist ein elektronisches Stellwerk beschrieben, bei dem die Soll-Beanspruchungen aller an den einzelnen Fahrwegen zu beteiligenden Fahrwegelemente in einer in einem Speicher vorgesehenen Tabelle abgelegt sind. Aus den Abweichungen zwischen Soll- und Ist-Beanspruchungen werden die Stellaufträge für die einzelnen Fahrwegelemente abgeleitet. Dies erfordert jedoch einen hohen Speicheraufwand, der mit der Grösse der zu steuernden Anlage deutlich zunimmt. Bei einem grösseren Bahnhof können u.U. mehr als 50'000 Start/Zielkombinationen einstellbar sein. Dabei muss gewährleistet sein, dass alle Daten der wahlweise einstellbaren Fahrwege korrekt gewählt und abgespeichert wurden, um die geforderte Sicherheit zu erreichen.
Ein nach dem Verschlusstafelprinzip arbeitender Steuerprozess kann einfach projektiert werden, indem eine Tabelle erstellt wird, in der die Lagen und Zustände der für die einzelnen Fahrwege vorgesehenen Stellelemente eingetragen werden. Die Fahrwege können daher einfach geschaltet werden, wodurch eine aufwendige Fahrwegsuche nach dem Spurplanprinzip mit den oben beschriebenen Problemen entfällt.
