Definitions
- the present invention relates to a method and a device according to the preamble of patent claims 1 and 10, respectively.
- target group information is stored in track elements which are provided in the vicinity of points lying at an angle, by means of which the route search is simplified.
- the correct definition and decentralized storage of the information in the corresponding storage units requires a corresponding effort.
- EP 0 683 082 A1 also describes a device in which the operator of a control system is relieved of monitoring tasks as far as possible. Switching state combinations that have already been set are read out by a display device and checked for compatibility with logical rules stored in a data processing system. These logical rules must be created when configuring a signal box and checked for correctness. In order to ensure comprehensive security, error-free logic rules must therefore be provided for all switching states that may occur with great effort.
- the present invention is therefore based on the object of specifying a method for the control and monitoring of a traffic control system having actuating and monitoring elements, by means of which at least two lanes for track-bound vehicles can be set with little effort, taking into account high safety requirements. Furthermore, a traffic control system working according to the method according to the invention is to be created, which can be configured with little effort and which ensures a high safety standard.
- the method according to the invention allows the simple project planning of traffic engineering systems, in particular of electronic signal boxes in railway engineering.
- the use of two independent control and monitoring methods results in less effort for project planning of the system and increased operational reliability.
- With the request to set up a route all control elements belonging to this route are blocked by a control process in relation to other requests to set up further routes and controls and are then made, each of the changes in the positions or states of the control elements to be carried out by the control process only after successful Admissibility is checked by an audit process that is independent of the tax process.
- the control process can therefore with can be realized with less effort, since the safety verification is carried out by a test process that is independent of the control process due to a diversified check of the admissibility of changes in the positions or states of the control elements.
- the control process preferably works according to the closure panel principle.
- the monitoring of the assembly and, if necessary, also the dismantling of the guideway, which is caused by the control process according to the locking panel principle, is carried out in this case according to the Spu ⁇ lan principle, by checking on a case-by-case basis whether the actuating and / or monitoring elements to be blocked and provided for an already created route can be used and are therefore already saved.
- the control process which works according to the locking panel principle, can be easily configured by creating a table in which the positions and states of the control elements provided for the individual routes are entered.
- the routes can therefore be switched easily, eliminating the need for a complex route search based on the Spu ⁇ lan principle with the problems described above.
- To check the positions and states provided by the control process for the actuators through the test process advantageously takes place according to the principle of the Spu ⁇ lan, by which all positions and states of the actuators blocked for other routes are taken into account.
- the positions and states to be switched are therefore not checked on the basis of a large number of logical rules created in advance, but on the basis of the actual state of the entire system. This comprehensive inspection results in increased operational reliability.
- the test is carried out according to the Spu ⁇ lan principle with little effort, since the correct and complete creation of test rules for route setting, which is associated with a great deal of effort, is no longer necessary.
- the control process is also possible to implement the control process with reduced effort according to the Spu ⁇ lan principle.
- the test process which is independent of the control process, is implemented in this case according to the locking panel principle.
- the measures according to the invention therefore, adapted to a planned track topology and to a required security level, allow a system control based on two independent processes to be implemented with the least possible effort.
- the control process for smaller plants is preferably implemented according to the sliding table principle and for larger plants according to the Spu ⁇ lan principle. Larger expenses for the implementation of the control process do not apply, however, since the required safety certificate can be more easily fulfilled by using the test process that is independent of the control process.
- FIG. 1 shows a railway system with two tracks running in parallel, which can be connected to one another via two connecting tracks and two switches each
- FIG. 2 shows the layout of the system according to FIG. 1
- 3 shows the Spu ⁇ lan of a created route from C to B
- Fig. 4 shows the Spu ⁇ ian of a created route from A to D.
- FIG. 1 shows a railway installation with two tracks GL1, GL2 running in parallel from A to B or from C to D, which have two connecting tracks GL12, GL21 and two points W1, W3 and W4 connecting to these connecting tracks GL12, GL21 , W2 are interconnectable.
- the tracks GL1, GL2 are divided into different areas, which are monitored by Freimeldem FM1, ..., FM14.
- the track areas around the turnouts W1, ..., W4 up to the middle of the associated connecting track GL12, GL21 are monitored by the free detectors FM3, FM5, FM10 and FM12.
- Signals S1, S4, S5 and S8 are provided following the areas associated with the free detectors FM1, FM7, FM8 and FM14.
- Signals S2 and S3 or S6 and S7 are assigned to the areas belonging to the free detectors FM4 and FM11.
- the track elements S1 S8, W1 W4, FM1, _ .., FM14 are in the states given 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. (Element) Track 1 Track 2 Track 3 Track 4 Track 5
- a command is drawn up according to the locking plate principle and an independent check based on the flushing principle.
- the inspection according to the Spu ⁇ lan principle guarantees a high level of security. Since the route search and process control based on the Spu ⁇ lan principle is no longer required, there is little effort for the project planning and implementation of the test process.
- the monitoring of the set-up and possibly also the dismantling of the route by the control process according to the locking panel principle is carried out according to the Spu ⁇ lan principle by occasionally checking whether the actuating and / or monitoring elements to be blocked and set for an already created route are used and are therefore blocked.
- control process and the independent test process can be controlled by software that is stored in parallel or separately operated computers or even in a single computer.
- the control process is controlled by a control process computer PR1 and the test process is controlled by a test process computer PR2.
- the control process computer PR1 has a memory which is used, among other things, to store the data on the closure panel.
- the test process computer PR2 has a memory which is used, among other things, for storing the set travel routes and preferably also for storing the Spu ⁇ lanes of the monitored route network.
- the control of the control elements and the monitoring of the states of the track elements is carried out 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 against other requirements for routes and operations. If route 5 has already been set, the states of the track elements belonging to 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, old 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 Spu ⁇ lan principle based on the actual positions of the control elements and the information provided by the monitoring elements and taking into account the routes already created, especially with regard to enemy routes Edge protection checked and released if no conflicts are found. However, if an error occurs in the control process and e.g.
- Signal S3 is to be set to run, although signal S3 is set to stop for route 5 already created (see Table 3), this is immediately determined by the test process on the basis of the states of the track elements associated with route 5 in the test computer, after which the control process stopped and an error is reported.
- the test process can also determine whether the flank protection is guaranteed for the set travel path.
- the side protection is ensured by the switch W1 and the signals S3 and S8.
- the switch W1 is locked in the "straight” state and the signals S3 and S8 in the "stop” state.
- the edge protection is guaranteed by the signals S2, S5 and S4.
- the signals S3 and S8 blocked in the "Halt" state.
- the test process can again determine whether there are conflicts with the other routes or regulations. After the route has been released (for example, route 1 has been released after route 5 has been dismantled), its data become available stored in the memory of the test process computer PR2 and used to check the actions of the control process.
- the control process can be used to set a route after an order has been placed, e.g. it is determined whether the elements designated in the corresponding line of the locking board (table) are used for other routes, or reserved or released for switching (the control process therefore sees no route, but the arbitrarily arranged elements of a line of the locking board).
- the check is carried out according to the Spu ⁇ lan principle.
- the test process which works according to the Spu ⁇ lan principle, has the data of the track topology at least for each adjustable route. The check can be carried out with more or less effort. For example, is only checked whether the changes intended by the control process lead to the correct setting of the route. E.g.
- 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 the elements specified in one line of the closure panel. After a successful test, the route will be stopped altogether. It is also possible to carry out the test before changing each element.
- the test process operating according to the Spu ⁇ lan principle is linked to a parameter list which allows customer-specific settings to be checked which are carried out by the control process and which are independent of the topology of the route to be set (for example, for a route , which serves the express train traffic, a decentrally arranged signal lamp can be integrated).
- the signal lamp is therefore included as an element in the relevant line of the closure panel and monitored by the test process using the parameter list.
- control process is carried out more simply according to the sealing board principle in small systems and more simply according to the Spu ⁇ lan principle in larger systems (the testing process is accordingly carried out according to the Spu ⁇ lan or sealing board principle).
- the control process can be implemented without major differences in terms of effort according to the closure panel principle or the Spu ⁇ lan principle.
- systems tend to grow and products gradually, with each generation a larger one Should have scope of services.
- the choice of principle for the implementation of the control process must therefore be made on a case-by-case basis, taking into account the existing framework conditions and the development forecasts made.
- the scope of performance of both processes is preferably coordinated with one another, taking into account the overall security requirements to be met.
- the performance of the control process can be reduced in relation to the fulfillment of the safety requirements if the scope of services for the test process is chosen to be correspondingly larger.
