Abstract

The invention relates to a method for controlling and monitoring a traffic installation comprising control and monitoring elements, notably switch points (W1, ..., W4), signals (S1, ..., S8) and track non-occupancy indicators (FM1, ..., FM14). By means of a control process based on a track blocking table, which in response to a request for the establishment of a route blocks and controls all setting elements associated with said route such that they are unavailable to other requests for the establishment of other routes and operations, at least two routes for rail vehicles can be set. At least one parameter (1, 2, 3, 4) is assigned to the installation elements (W1, ..., W4; S1, ..., S8; FM1, ..., FM14) which relates to the conditions or assignments to be defined or taken into consideration for each intended route, so that by means of a parameter (1) assigned to the track non-occupancy indicators (FM1, ..., FM14) the track non-occupancy indicator (FM1, ..., FM14) sequence along a route is defined and by means of a further parameter (1) assigned to the other installation elements (W1, ..., W4; S1, ..., S8) the association of said other elements with at least one of the track non-occupancy indicators (FM1, ..., FM14) is defined. As a result of the above parameter assignments the control process based on said assignment permits a simple and safe control of the installation to be controlled. The above control process is further made easier to carry out by the complete and technically executable description of operating conditions. The measures provided for in the invention also permit a more rapid establishment and suppression of travel routes and recognition of disturbances in track non-occupancy indicators.

Description

The present invention relates to a method according to the preamble of patent claim 1.

Various procedures are used in signal boxes for railway traffic to create routes to use. Interlockings operating according to the locking panel principle are based on use of closure and isolation tables shown in [2], Fig. 25 and Fig. 26, in which the static Condition of system elements such as level crossings, tracks, track blocks, signals and switches for the intended route settings are shown. For rules and sometimes also process-dependent Relationships between the investment elements by the operational rules and geographical Peculiarities are determined, additional conditions are given in footnotes to the tables, that must be taken into account when controlling individual system elements. The wording of this In practice, additional conditions are not unique for all conditions. The completeness of Description of the system, the safe formation, monitoring and resolution of driveways is therefore hardly ever guaranteed by means of a lock and isolation table and footnotes. dependencies between routes that arise or change during the processes are not recorded. For the correct implementation of the lock, isolation table and footnotes become projectors needs, which may need to be considered when controlling the system elements recognize and master them based on their professional experience. It is the exact knowledge of the entire range of functions of the interlocking system modules required.

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, which is easy to implement for systems with any route structure.

This object is achieved by the measures specified in claim 1 solved. Advantageous embodiments of the invention are specified in further claims.

The method according to the invention allows the simple project planning of traffic engineering systems, in particular of electronic signal boxes in railway engineering. According to the invention, the control processes provided for the construction and / or dismantling of the travel routes are based on the complete assignment of parameters to the system elements. Furthermore, the track vacancy detection devices are listed depending on the order in which they are passed when driving on the route to be set. In particular, this allows the availability of the traffic system to be increased. Routes can be dismantled and rebuilt more quickly. In addition, faults are easier to identify and correct.

• The system elements intended for monitoring and clearing track sections, hereinafter referred to as free indicators, are now assigned parameters for each route to be created, by means of which the sequence of the free indicators within a route to be set is determined.
• At least one parameter is assigned to the further investment elements, by means of which the assignment of an investment element to one or more vacant notices is determined.
• If necessary, further parameters are assigned to the system elements, which contain control-relevant information. This eliminates footnotes to the tables.
• Complex operating conditions are preferably recorded in a table having at least one row and described in full. From this, the state of a logical parameter is determined, which can be assigned to the system elements.

The control processes provided for the construction and / or dismantling of the travel routes are given in the table specified assignment of parameters to the system elements clearly with little effort and can be implemented safely.

The invention is explained in more detail below using a drawing, for example. One is shown Railway installation with two tracks GL1, GL2 running parallel from A to B or from C to D, the via two connecting tracks GL12, GL21 and two each connecting to these connecting tracks GL12, GL21 Points W1, W3 or W4, W2 are connected to each other. The tracks are GL1, GL2 divided into different areas, which are monitored by (track) free detectors FM1, ..., FM14 are realized in the form of track circuits or axle counters.

A Freimelder FM processes the information from one or more track circuits and / or of axle counters. The determined state of the associated track section is sent to an interlocking reported. For security reasons, these messages become antivalent or redundant trained .. Track vacancy detection devices with direct or alternating voltage track circuits or Axle counters are e.g. in [1], pages 277-316 or in [3].

In the railway system shown, the track areas around the turnouts W1, ..., W4 to the middle of the associated connecting track GL12, GL21 are monitored by the free detectors FM3, FM5, FM10 and FM12. Following the areas associated with the free detectors FM1, FM7, FM8 and FM14, signals S1, S4, S5 and S8 are provided. Signals S2 and S3 or S6 and S7 are assigned to the areas belonging to the free detectors FM4 and FM11. The following routes can be created between points A, B, C and D starting from point A or point C (excluding ranger routes):

Route 1

from A via track GL1 to B,

Route 2

from A via track GL1, connecting track GL12, track 2, connecting track GL21 and track GL1 to B,

With the request to build a route (e.g. route 1), all associated with this route Control elements of a control process versus other calls to build other routes (e.g. one of routes 2, 3, 4 or 5) and controls blocked and then posed. Of course, other routes, such as shunting routes, driveways or Exits are made. To explain the invention, therefore, only the process for Construction and dismantling of route 5 explained. For this route, which is set using a control process the system elements S1, ..., S8, W1, ..., W4, FM1, ..., FM14 are in the following Table 1 states provided the conditions specified in the parameters are fulfilled.

The elements of a railway system to be controlled are assigned at least one parameter (or an auxiliary variable) that describes at least one possible state, condition or assignment that is important within a control process. All necessary parameters must be provided so that the control process can be fully and unambiguously implemented. Several parameters are preferably assigned in a parameter list as follows: elements parameter description States / assignments abbreviation give way 1 resolution assigned freelancer (FM No.) 2 location apportioned u just G 3 Function type roadway w flank protection s Durchrutschweg d free detector 1 Sequence in the route outside driveway 0 Position within the route (FW Pos.

T1 = A AND B;
T1 = A OR B Figure 1) List of parameters

Of course, the parameter list can be adapted to the needs of the project planner. Parameters can be changed, added or omitted. After adjusting the parameter list once to existing system elements, further changes should no longer be necessary or should be avoided. Based on the parameter list, which can now be used for the elements of any system, a table is created for a system to be configured, in which the parameter values or the possible states and assignments of the system elements for all required routes are specified.

Table 2 shows the parameter values and the possible states and assignments of the system elements for route 5. A column is provided for each parameter to be taken into account. The complete one Table with the parameters for all system elements includes a total of all five routes twenty columns plus one column for the list of investment items. The conditions for the investment elements are given in 29 lines.

By means of this closure table expanded according to the invention in connection with the parameter list all conditions for the control of the plant or for the creation and dismantling of the Routes completely and clearly described. Based on the lock table, a Control program that can run on a system computer manually or preferably automatically to be created. Due to the technical workability of the lock table, in which all conditions and assignments are specified in full, the control program can by a Program generator are generated automatically.

Additional conditions for any investment elements that were previously only taken into account with great effort could be inserted in new lines. By one on another line provided logical link T1 of several conditions can also more complex conditions be taken into account. These conditions or relationships of conditions can be used as parameters in other lines.

Through this complete and problem-oriented in a uniform, technical syntax (see Tables in Fig. 1 and Fig. 2) for the control of the process it is possible to Review of the results of the positioning process running on a data processing system for the Setting and dissolving routes to use the description directly. This allows errors in easily determine the processing of the computer system.

The first one provided in the lock table is particularly important for an advantageous control of the system Parameter by which the FM free detector is identified in its order in the route and the other system elements (switches, signals, etc.) at least one vacant detector FM can be assigned. These measures are particularly related to the warranty Increased security during the control process is an advantage. Furthermore, through these measures the availability of the routes increases. Sections of set routes can due to the fixed order of the FM free signal after the vehicle has passed through again be released, whereby a partial dissolution of the route is achieved. The "dissolved" Sections of the driveway are therefore already available for the construction of further driveways Available if the vehicle has not yet reached the end of the route. By A clear signal FM is registered when a vehicle passes through a track section, so that all system elements assigned to the Freimelder FM can be released as soon as the Section is decoupled from the driveway.

The first parameter of the list given, for example, in Figure 1 for the system shown was explained above. Parameters 2 and 3 for turnouts relate to the adjustable position or the function that the Which takes up in the driveway. For example, is not driven on, but serves as side protection, through which enemy trains are kept away from the set route. Parameter 2 for free detectors concerns the condition to be fulfilled for the changeover of the start signal to green (or trip approval). parameter 3 specifies the criteria used to monitor a section. Parameter 4 specifies which The route, or preferably a section of the route, is thus to be met or released. Parameter 2 for signals defines the function of the signal. Parameter 3 gives the Driving term to be displayed and parameter 4 specifies the condition for the signal change is fulfilled.

When controlling the system, special requirements of the user may have to be taken into account, which to a special operating regulations or a special geographical embedding of the controlling system are supported. Therefore, additional lines are preferably provided, in which additional Conditions are specified that are used as parameters in the lock table (e.g. as parameters No. 4 for the placement of signals) must be taken into account. Multiple conditions can also be in one additional line can be linked. In the lock table, line 29, they are in line 27 and line 28 specified conditions A and B AND-linked. The result of the link created by the variable T1 is represented, is in the line 5 provided for the signal S5, under parameter 4 as a condition specified. The signal S5 should only be changed to a driving concept of driving, if through the barrier BA1 shown in the drawing and a monitoring device BÜ the associated level crossing was secured. In this way, any other application-specific Conditions are taken into account. Conditions A, B, ... can, i.e. Naturally also be considered individually in lines 1, ..., 26.

In larger table formats, the elements FM, S, etc. are preferably in the columns and Parameters specified in the lines.

The solution according to the invention can also identify occurring errors and correct them at the process logic level. In today's signal boxes, track sections are monitored, as mentioned above, for example by means of axle counters and / or track circuits. A logical combination of the count results from two axle counters determines whether a train has passed a section of track and has left it completely. If a train has passed the relevant section of the track and the axle counters have different counting results, the route is not resolved in known systems. The fault is difficult to localize today due to many possible influences. By logically linking the counting results of several successive sections of axle counters to each other, error corrections are possible directly in the axle counting logic. The effort for such a network among axle counters is great.
According to the invention, however, it is determined in what order the vacant detectors are arranged and passed within a route. Free detectors are axle counters and / or track circuits or other devices for detecting the occupancy of a rail section.
In the table below, the lines of the locking table are sorted according to parameter 1 (the values of parameter 1 increase steadily from line to line.) From the drawing it can be seen that the order of the free detectors FM8 FM9 FM10 FM11 FM12, FM5, FM6 and FM7 corresponds to the sequence of the track sections that are traversed sequentially when using the route 5.

For the dissolution of the route, the condition If (occupancy and release) is specified under parameter 4. Each of these track sections must therefore be occupied before the dissolution and be free again.

If the free detectors FM8, FM9, FM10 and FM12 fulfill the condition If of parameter 4 report (track section occupied and released again), it can easily be ascertained that with free signaling FM11 an error has occurred. To verify this, the reports from further free detectors (FM5, FM6 and FM7) are awaited. Then after editing of the fault pattern using logical rules if necessary and possible permitted by rail technology Corrective measures initiated when the track sections are released. The busy driveway can be blocked or completely or partially dissolved in accordance with the security rules provided become. If corrections are not permitted, i.e. no misconduct is recognized, can lead to optical Inspection of the relevant track section may be requested (e.g. it is checked whether there is a wagon detached from the train composition). In addition, the axle counters, which may be faulty and / or Glelsstromkunden be subjected to a test procedure or, if necessary, until Maintenance deactivated and functionally substituted. It is particularly advantageous that the necessary Corrective measures based on detailed error information targeted at the Process control level can be applied.
