Abstract

The route device (SG) has a number of logic modules (LG1 to LG4) which are matched to the number of track sections (1 to 4) of a route area. These logic modules are represented by multi-computer systems which are reliable in terms of signalling technology; they are connected to one another via bus systems (B1; B2, B3) and to the signalling box (STW). Each logic module (e.g. LG3) determines, from fixed and variable route and, if appropriate, vehicle data impressed on it and transmitted to it from the signalling box and the other logic modules, the data telegram which is to be transmitted to a vehicle (F) travelling over the associated track section (3), and ensures the said data telegram is transmitted to the vehicle. <IMAGE>

Line device for line train control in railways

The invention relates to a line device according to the preamble of claim 1.

From DE-PS 32 42 199 a track circuit arrangement is known, which in addition to the actual track monitoring also for the transmission of information between a The control station and the vehicles traveling on the track circles are used »Each track circle consists of one in the Rails feeding transmitter and one connected to the rails, on the respective track circle frequency Matched receiver, If the track is free, the receiver receives the information transmitted by the transmitter over the rails Track streams and reports the associated section free. If the track section is occupied, the recipient will de-energized and initiates the occupancy message of the track section. For neighboring track sections are different track circle frequencies provided; to increase operational safety are the track currents Section-specific identifiers are modulated in the individual sections. If the track is occupied, the Track currents from the control station modulate signals that the train protection and possibly also the train control to serve. The vehicle receives these signals via receiving antennas that are inductively coupled to the rails on. It can differentiate between the track monitoring and the train protection serving track currents.

The data required for train protection are carried out in the known track circuit arrangement a so-called control device is made available, which is not further explained there. In this Control devices are unchangeable and to form the data telegrams to be sent to the vehicles evaluate and link variable data, some of which is associated with the respective track section and partially to be assigned to adjacent track sections.

The linking and evaluation of this data has so far been done regularly in a so-called line device, which is provided for a certain number of track sections forming a route area, and from the The changeable and unchangeable data of the train protection and, if applicable, the vehicle control system, which are accessible to all of them serving data telegrams worked out.

Such a line device is specified in DE-PS 11 76 698, for example. There, by querying Memory switching means for occupancy reports determines the free route in front of each vehicle formation, at the same time, by querying other memories, the maximum speeds permitted in the individual sections determined and included in the data telegrams to be sent to the vehicle associations. at This known track unit only a few will influence the advance speed of a vehicle formation Parameters included in the data determination. The telegram formation becomes more and more complex more influencing factors have to be taken into account. For example, in the case of track branches, the respective position plays a role The relevant switch plays a role because the straight switch branch generally results in a higher driving speed is permissible than over the angled

Branch. In the determination of the train protection and possibly also train control serving data telegrams are then to include variable data depending on the route set in each case. Telegrainm formation is still going on more complex if the same driving behavior is not assumed for all vehicles or vehicle associations instead, different starting and braking properties must be taken into account.

The object of the present invention is to provide a stretching device according to the preamble of claim 1 indicate that in the case of inclusion and consideration The most diverse parameters for train protection, both in terms of the mechanical structure and the project planning of the device concerns a simple, inexpensive and above all a clear structure. Such a route device that is still largely manageable for the user has the advantage that it is easy to maintain and relatively easy to adapt to new circumstances, for example with regard to the consideration of changes in track-specific route data in the individual track sections can be adjusted.

The invention solves the problem by using the features specified in patent claims 1 or 2.

Both in the claims 1 and 2 specified stretch devices show a modular structure, in particular for a train protection system that can be expanded in stages. Advantageous configurations the track devices according to the invention are specified in the subclaims.

The invention is described below using an exemplary embodiment shown in the drawing explained in more detail. The drawing shows one of four track sections 1, 2, 3 and 4 in the lower part Route area with a vehicle formation F driving on section 3 in the direction of the arrow, above the Switching means GK for monitoring the track sections, above an embodiment of the track device according to the invention SG and symbolically indicated above the interlocking STW for specifying the route data. The switching means GK for track monitoring in the assumed route area are preferably housed in a common switch cabinet or housing. The inventive Line unit SG is housed in the same control cabinet or housing, preferably in Form of one or more additional plug-in units for the one or more of the monitoring switching means GK Racks.

The monitoring switching means GK for the track monitoring essentially consists of the transmitters S1, S2, S3 or Sh for feeding track currents into the individual track sections, as well as corresponding receivers, not shown, for decoupling the track currents and triggering vacant and occupied messages. The feed of the track streams always takes place against the direction of travel of the vehicles indicated by an arrow. The track currents used for track monitoring are coded according to a section identifier in the memories C1, C2, C3 or C4 and the track circuit receivers assigned to the individual sections monitor the amplitude of the respective track current as well as the codings attached to them. When occupying a track section changes

-Sf- VPA 84 P 2 9 3 3 OE

an associated switch U1, U2, U3 or U4 in the each other switch position. In this switch position, the respective associated transmitter will be replaced the section identifiers for the track monitoring from the track unit SG supplied data that the train protection and if necessary serve train control. In the illustrated embodiment, only the track section is

3 has been accepted as occupied. According to this assumption, the switches U1, U2 and U4 lead the associated Send the for track sections 1, 2 and

4 provided section identifiers, while the switch U3 the connection between the line device SG and the transmitter S3.

Trained according to the invention track unit SG consists of one of the number of track sections of the each controlled route area corresponding number of logic modules LG1, LG2, LG3 or LG4. Every Logic module is for the transfer and transfer of data via BUS lines B1 with the logic modules of the respective adjacent track sections connected. It is also available via further BUS lines B2 or B3 and converters ¥ 1 or ¥ 2 connected to the STVi signal box. Each logic module consists of a signaling component Secure multi-computer system with parallel development of work results and comparison of work results before their issue. The multi-computer systems are not shown in the drawing signal-technically safe input duplicator operated, so that it is ensured that each individual computer of a logic module via the BUS lines is always supplied with the same data. Each logic module has read-only memory in which for

-β- VPA 84 P 293 3DE

unchangeable route data for the track section concerned, for example on the length of the section, the inclination of the track, the frequency of the associated track circle transmitter, the frequency of the neighboring track circles and permissible maximum speeds are stored. These read-only memories are preferably designed as EPROMs, which can be adapted to the new conditions when the route data is changed. Any logic assembly also has read / write memory, in the interlocking and from the logic modules of the neighboring Track sections, variable route and, if necessary, vehicle data can be transferred. This data can refer, for example, to certain maximum permissible driving speeds in the individual sections, which vary depending on the signal or are caused by temporary slow driving parts. To the changeable Route data also includes the data to be taken over from the interlocking regarding the position of in the route lying turnouts, whereby the respective turnout position necessitates the specification of different travel speeds can. Each logic module calculates the permissible advance speed from the data available to it for a vehicle group traveling on its assigned section, with the data that could lead to speed restrictions for an approaching vehicle formation via the bus system advances to the logic module that is connected to the track section following against the direction of travel assigned. She also transfers information that relates to the driving characteristics of a vehicle group the bus system to the logic module following in the direction of travel, which may contain this information when determining takes into account the data telegrams to be sent to the approaching vehicle.

For the processing of the data traffic between the logic modules and the interlocking are advantageous separate bus systems B1 and B2 or B3 to be provided, whereby to achieve the best possible Real-time behavior at least for communicating the Logic subassemblies are to be provided with a bus system having several separate buses. This Bus system or these bus systems can be as shown in Auführungsbeispiel be ring bus systems; it however, parallel bus systems or other bus structures can also be selected.

In the same way as the logic modules assigned to the neighboring track sections of a route area To exchange data with one another, they also have data with the logic modules for the adjacent track sections 0 and 5 of the neighboring route areas to be exchanged. This is done via those included in the bus system Coupling modules K1 and K2 and modems M1 and M2, which establish the connection to the line devices of the neighboring Create route areas.

In the illustrated embodiment it is assumed that the logic modules represented by multi-computer systems from the data known to you, the data used for train protection and possibly train control itself work out and send them to the vehicles in the form of data telegrams. However, it is also possible to send these data telegrams not to be regenerated from case to case, but completely in memories of the logic modules to be stored and retrieved as required. The multi-computer system determines which data telegram is to be retrieved the relevant logic assembly from the data,

which are transmitted to him by the signal box or the logic modules of the neighboring track sections.

In the exemplary embodiment shown, the logic modules are connected to one another via the bus connections connected as the associated track sections follow one another according to the track plan. From this lane planned Connection of the logic modules to one another can be disconnected when the control of the logic modules is made address-oriented. That which is to be advanced from one logic module to another logic module The data telegram is then advanced on the bus system from logic module to logic module as long as until the respective addressee is reached.

It can be advantageous for processing the telegram traffic between the logic modules and the interlocking be to set up a bus management, via which the individual logic modules the use of the bus according to certain Criteria is assigned. This bus management also ensures proper takeover and phasing the data originating from the logic assemblies of neighboring line devices into the data flow of the bus systems.

A particularly advantageous embodiment of the invention provides for n, preferably adjacent, track sections to assign a common logic assembly and the secure multi-computer system as η von η computer system to train. In this embodiment of the invention, all computers work independently of one another the data telegrams to be sent to vehicles in the relevant track sections or select these data telegrams and compare the telegrams before their

Output to the process for consistency. Each of the from the common logic module with telegrams to supplying track section is served by another computer in the computer system. Is for two at a time If a common logic module is provided for track sections, the secure multi-computer system is 2 represented by a 2-computer system, in which each individual computer after comparing the data telegrams it has worked out with the data telegrams of the other individual computer these data telegrams to the one or the transmitted to another track section. This embodiment of the invention is still clear in its structure, but less complex than the solution in which each track section is assigned its own logic module is.
