EP1893464B1 - Method for the formation of random logic operations in a control unit, and control unit - Google Patents

Abstract

The aim of the invention is to create a method and a signal tower for regulating rail-borne traffic which make it situatively possible to implement and apply rather complex processes for safely establishing and/or canceling routes in the signal tower logic without having to make adjustments to the generic portion. Said aim is achieved by a method and a signal tower for monitoring and/or adjusting/canceling a route for a rail-borne vehicle. According to said method, a route is adjusted or canceled upon request by means of units allocated to the respective route once the units connected to the desired request have not negatively acknowledged said request. Attributes associated with the route, especially the track occupation, direction of travel, block interlocking, barriers, are defined by means of expected values, and the route is adjusted or canceled only once the expected values have been provided for the defined attributes. This makes it possible to introduce other supporting requests into the logic for establishing and/or canceling a route in addition to the units directly involved in the route, e.g. positioning elements such as switches and signals, and monitoring elements, such as axle counters and clear track signaling systems. Such supporting requests primarily contribute to further increasing the great degree of safety provided as a matter of fact.

Description

The present invention relates to a method for configuring an instrumentation and control unit, in particular an interlocking, wherein the control unit is used for monitoring and / or setting / resolution of routes for rail vehicles by a driveway on request with the respective road assigned elements or resolved especially after this request is not negatively acknowledged for the elements associated with the desired request. Furthermore, the invention relates to a related control unit.

To explain the operation of a control unit in rail transport, in particular a signal box, for example, the European patent EP 0 920 391 B1 be used. By the term of a control technical unit is meant a control and / or monitoring unit. In principle, the method disclosed below and the subsequently disclosed control unit are also suitable for use in road traffic, in aviation or for other industrial and / or commercial control and / or monitoring purposes.

The method disclosed in the above-mentioned European patent allows the simple design of traffic systems, in particular electronic interlockings in the railway technology. The use of two independent control and monitoring methods results in lower project planning and increased operational safety. With the request to build a Driveway all adjoining this route driving elements of a control process against other requests for the construction of other routes and operations are blocked and then provided, each of the to be carried out by the control process change the positions or states of the actuators only after successful testing for admissibility by an independent of the control process Inspection process is done. The control process can therefore be realized with less effort, since the safety proof is based on a diverse review of the permissibility of changes in the positions or states of the control elements by a control process independent of the control process.

The monitoring of the caused by the control process according to the Verschlusstafelprinzip up and possibly also the dismantling of the track is carried out by the test process in this case according to the track plan principle by checking case by case, if the locking and to be set control and / or monitoring elements for a already created track are used and thus already locked. In principle, for example, the exactly opposite procedure is possible.

Optimum use of the track system with an ever increasing number of different vehicle types and complex track topologies with special conditions to be considered makes it necessary from the point of view of the optimized operating rules and generally taking into account the interoperability that the possibility of a differentiated road formation, driving route monitoring and resolution situational should exist depending on other state variables. This differentiation goes beyond the possibilities of today used track plan and Verschlusstafelverfahren - such as in the EP 0 920 391 B1 revealed - beyond.

The present invention is therefore an object of the invention to provide a method for controlling the rail-connected traffic and a related control unit, with which it is situational possible, more complex processes for the safe formation, permanent monitoring and / or resolution of routes in the logic of the control unit implement and apply.

This object is achieved with respect to the method according to the invention by a method of the type mentioned, in addition to the already directly involved in the road elements attributes for not directly involved in the road, but the road flanking elements, in particular track occupancy, direction of travel, block closure, Route lock, reduced signal concept, are defined with expected values and a requested route only after this request for the elements associated with the desired request is not negatively acknowledged and is set or resolved only after the existence of the expected values for the defined attributes.

Further, this object is achieved with respect to the process control unit according to the aforementioned type, in addition to the elements directly involved in the road attributes for not directly involved in the road, but the road flanking elements, in particular track occupancy, direction, block closure, line barrier , Reduced signal concept, are definable with expected values and a requested route only after this request for the associated with the desired request elements is not negatively acknowledged and only after the existence of the expected values for the defined attributes are adjustable or resolvable.

In this way, in addition to the elements directly involved in the roadway anyway, e.g. Control elements, such as switches and signals, and monitoring elements, such as axle, track free, even more flanking queries in the logic for the construction and / or resolution of a road in particular very flexible even be introduced only in the design of a signal box. Such flanking queries above all contribute to a further increase in the already high level of security.

1. a) die Zulassungsprüfung einer Fahrstrasse mit zusätzlichen einschränkenden Bedingungen;
2. b) die Überwachung einer Fahrstrasse mit zusätzlichen Überwachungsbedingungen;
3. c) der Signalfahrtbegriff für eine Fahrstrasse mit einer Einschränkung des Signalbegriffs;
4. d) die Aufwertung eines Durchrutschweges mit einer Einschränkung für die Aufwertung auf höherwertige Durchrutschwegvarianten;
5. e) die Zulassungsprüfung des Durchrutschweges mit zusätzlichen einschränkenden Bedingungen;

8. h) Für beliebige Bedienungen (Elemente und Fahrstrassen) kann die Zulässigkeit weiter eingeschränkt werden.

These queries can therefore be used, for example, to implement the following functions:

1. a) the approval test of a road with additional restrictive conditions;
2. b) the monitoring of a road with additional monitoring conditions;
3. c) the signal driving concept for a road with a restriction of the signal concept;
4. d) the revaluation of a slipstream with a restriction for the revaluation of higher-grade landslide variants;
5. e) the approval test of the slip path with additional restrictive conditions;
6. f) the monitoring of the slipping path with additional conditions for its monitoring; such as
7. g) a digital universal element which outputs the result of an attribute or a combination of several attributes via digital outputs and outputs this result also to the control and display system of the interlocking.
8. h) For any operation (elements and routes) the admissibility can be further limited.

In a particularly expedient development of the invention, it may be provided to define the attributes with their expected values in Boolean logic. In this way, several attributes can then be converted into one using Boolean logic Linking be merged. This linking of several attributes can then itself be an attribute within the meaning of this description, which can just be defined individually. This means that any AND and / or OR links of any attributes, which can also be clipped, can be linked to form a new attribute.

In order to be able to make the additional evaluation of the route condition with the attributes easily accessible in particular during the configuration and / or configuration of routes, the possible attributes can be selectable from a list in which the states to be monitored of these attributes and the expected values corresponding to these states are listed. It is also possible, depending on the type of configuration and / or configuration, to restrict the list to selective subsets in order to limit the amount of available selectable attributes to meaningful subsets.

For safety considerations, it is also advantageous in this type of route formation and / or resolution if the setting and / or resolution of the units assigned to the respective route is carried out according to the closure panel and / or track plan principle or if the adjustment and / or Dissolution process according to one of the two principles works and the test process according to the other principle.

Embodiments of the invention will be explained in more detail with reference to the drawing. Figures 1 and 2 each show an example of a join rule, which is composed of several attributes. These links are of course exemplary, other cases are individually feasible.

In order to avoid overfilling, the towing lane 1 may only be approved if the line barrier is in the "off" state and if the direction of travel in the block is present or the block lock is clear. In addition, it must be checked that the crane is in the parking position in order to avoid a possible hazard due to its swinging out into the area of the train route 1.

The linking rule R1 derived therefrom in the approval test of the train route would in this case be formulated as follows: $$\begin{array}{c}\mathrm{R}1=\mathrm{crane}\left(\mathrm{parking\; position}\left(\mathrm{one}\right)\right)\wedge \mathrm{block}\left(\mathrm{distress}\left(\mathrm{distance\; lock}\left(\mathrm{one}\right)\right)\right)\wedge \\ \left(\mathrm{block}\left(\mathrm{direction\; of\; travel}\left(\mathrm{available}\right)\right)\vee \mathrm{block}\left(\mathrm{block\; closure}\left(\mathrm{free}\right)\right)\right)\end{array}$$

The above link is therefore composed of the four attributes crane (parking position (on)) KKrK and block (emergency stop (on)), block (direction (present)) and block (block lock (free)) , the latter two OR-linked and this result is AND-linked with the first attribute.

Depending on the track topology, additional dependencies must be taken into account to avoid endangerment at stations without rail-free access to the platform.

If 2 routes are set in the track, or if there is a train there, then it must be expected that people from the station building will enter the platform via track 1. In these cases, train passes through track 1 must be prevented.

An association rule R2 in the approval test of the routes to track 1 would in this case be formulated as follows: $$\mathrm{R}2=\mathrm{G}12\left(\mathrm{assignment}\left(\mathrm{free}\right)\right)\wedge \mathrm{B}2(\mathrm{distress}\left(\mathrm{target\; stress}\left(\mathrm{one}\right)\right)\wedge \mathrm{C}2(\mathrm{distress}\left(\mathrm{target\; stress}\left(\mathrm{one}\right)\right)$$

It is easy to understand that the join rules can take on an almost unlimited size and arbitrarily deep nesting of the parenthetical expressions can be interpreted. This is due to the fact that no (finite) list entries, but associations, which can be (infinitely) linked, are used here. This is based on object-oriented principles and thus allows only the unlimited size and thus the degree of easily definable individualization.

By means of the linking rule, element states can be monitored element-by-element by driving lanes, routes and slip-roads as well as the universal digital elements and linked to a result according to a configurable formula in the form of the linking rules. If the result of the configurable link is true, for example, "RgTrue" can be output as the result to the process that requested the evaluation of this link rule. In all other cases, the result would be "RgFalse".

The association rule can thus be applied when states of elements that are not claimed by the currently desired roadway, but must be tested and / or monitored by the road, and / or if checks, monitoring or exclusions that do not implement in the road logic must be realized in special applications, and / or when cross-element states must be linked together and the result of the link should either be displayed or output via digital outputs.

An exemplary overview of such monitorable states of elements relevant to the routes can be found below:

This tabular representation shows on the left the special elements important for a road with their associated attributes (machines) in the center of the table as well as the monitored states on the right side, which can be characterized as expected value. By way of example, the first line shows that the attribute "track load" is defined for a turnout WE and the status "on" is monitored. If this condition exists, the result is TRUE or RgTrue. If it is not available, the result is FALSE or RgFalse.

In the configuration of a route on the workstation, the attributes of the various elements contained in the table below can now be combined in the desired manner, as shown above for the rules R1 and R2.
