Abstract

A circuit is used to regulate the control system of a railway marshalling yard. A set of route relays is provided for all the tracks and points, and they are operated by a series of circuits on signalling the starting and end points of a movement in which an interconnection between relays to carry information necessary in setting up the route is carried on special lines instead of the normal track lines. These special lines run between relay groups of different starting or end points and they are cheaper and simpler to instal than normal track lines.

Description

The invention relates to a circuit arrangement for setting routes in lane plan signal boxes with the route relays assigned to the switches and tracks, which each switch to the The start and end point of the selected route characterizing key relay of an assigned Address the relay group in a chain via lane lines that are passed through between these relay groups and trigger the setting of the route.

It is known that the individual route elements such. B. Switches and Track sections, assigned relay groups by spur lines of pluggable spur cables accordingly the geographical location of the route elements in the track connected to each other. The spur lines will be for triggering predetermined switching processes in the route or signal control circuit when forming a route between the respective

croad-based relay group of the destination point through all route-related turnout relay groups up to the respective route-related relay group of the destination point .

For conservative reasons, the number of possible spur lines is limited. So that the operational requirements that usually occur can be met, the spur lines have to be used several times. In unfavorable cases, however, the number of existing lane lines is not sufficient, even if they are used multiple times.

Ip lane plan signal boxes is the transmission of certain additional information in the route formation often only between the relay groups of Starting point and destination point of the selected route are required, but not for the relay groups of the other route elements. Such information transfers are necessary, for example, when at the destination point of the route during route formation the activation of a slip path of depends on the type of signal at the starting point of the route or if a at the route destination point Driving exclusion is to be effected, which also depends on the type of signal at the starting point of the route depends.

The invention is based on the object of providing such additional information that is generated during route formation are to be transmitted, not via a separate track line but via a different line transmitted, the transmission path should be cheaper than the very expensive for structural reasons Tracking.

According to the invention, this object is achieved in that for transmitting additional information to the Identify different starting points or destination points of routes, from the relay group of the relevant end point to the relay group of the other end point separate lines are provided all relay groups of start and relay groups that are eligible for the transmission of the same information Target points are connected and these lines through to the relay groups providing the information a normally open contact of the associated button relay to voltage and to those that require the information Relay groups can be connected to a receiving relay using a normally open contact of the associated button relay are, at least either in the relay groups of the starting points or those of the target points for Normally open contact of the key relay a normally open contact of a route relay that is only activated if the selected route picks up, is connected in series.

The E ^r invention is based on the knowledge that all circuits for route formation must be designed in such a way that route formation only comes about if only a start button and a destination button are pressed in the control table to select the route or their button relays in the associated relay groups are activated , otherwise a clear route formation is not possible. If you now connect all your additional information for the transmission of your additional information in the route formation in question ('5 starting points and destination points via a separate line and connect this line to the voltage of the Rclais group of the respective starting point and to a receiving relay for the relay group of the respective destination point This gives you a schematic transmission path with only one line that is valid for any factory road settings. Via this line, additional information, which, for example, specifically identifies the starting points of routes, can be transmitted from the relay group of the respective starting point to the relay group of the destination point without the out line on the type of track lines on all relay groups of switches located in the driveway, and the point position must be switched accordingly there. There are, therefore, all else notwen in the relay groups of switches at transmission via tie lines digen switching elements saved, z. B. Through-sound contacts and group outputs with the associated very expensive connectors.

Characterized in that at least either at the starting point or at the destination point to the normally open contact of the key relay, a normally open contact of a route relay, e.g. B. route connecting relay or test relay, which only picks up if the selected route is permitted, is also connected in series, so that the information transfer via the separate line only comes about if the desired route is actually permissible or track-wise possible.

You can go with. the circuit arrangement according to the invention also provides additional information on Identify the destination points of routes during route formation from the respective destination point Transferred to the respective starting point if the separate line is switched to a receiving relay at the starting point and to voltage at the target point. Man can be at the start or destination points where there is a normally open contact of the route relay in the inrush current branch is arranged. also omit the normally open contact of the button relay. Then it can be because of the chain-like switching of the route relay, for example, initially one from the starting point Information is transmitted to all target points that can be reached by it; the route relays of all non-selected target points are discarded again in the further course of the route formation, see above that only the information transfer between the selected starting point and the selected destination point persists.

In the same way, additional information can also be transmitted from the starting point to relay groups of switches or track sections located between the starting point and destination or behind the destination of the selected route or slip paths to be switched on behind the route destination. With these relay groups, you only need to switch the separate line to a receiving relay via a normally open contact of an associated route relay. You can also reverse the direction of the information transmission and, for example, transmit additional information from the relay group of a switch or a track section located between the starting point and the destination point or behind the destination point of the selected route to the starting point, if you connect the separate line to the corresponding relay groups via a working contact of a The route relay is connected to voltage and at the starting point to a receiving relay.

For routes that follow one another in the direction of travel, where the destination of the first route is also

The starting point of the second route is and where there is also a third route from the starting point of the first can be adjusted up to the destination of the second route, it may be necessary when setting the third Route additional information from the starting point of this route to the transferred destination point the first route is transmitted, but that this additional route when the first route is set Information is not transmitted to the target point. One can then use the separate line for the additional Information at the destination of the first route via a normally closed contact of the button relay and a related in Switch the normally open contact of the route relay switched in series to a second receiving relay. at When the third route is set, the information is transmitted to the second receiving relay. When setting the first route, whereby on When the key is pressed and the associated key relay picks up, it is activated by opening the Normally closed contact of the button relay prevented. The same normally closed contact also prevents the separate line to the second receiving relay, if the destination button of the first route is set the second route can be used as a start button. When setting the third route, the prevents Normally open contact of the button relay that is not picked up, the information transmission to the first receiving relay of the target point.

The transmission of additional information when the route is formed can be provided, for example when a route is set from an entry signal to an exit signal on At the end of a station track behind the exit signal, a slip path is to be switched on Route setting from a track blocking signal dividing the station track to an exit signal or beyond that behind the exit signal but no slip path is to be switched on. It is advisable to switch between a track blocking signal and a Exit signal or beyond the transmission of additional information from the track blocking signal to for the exit signal and the formation with the receiving relay that picks up at the exit signal prevent a slip path.

The circuit arrangement according to the invention can also be used to produce very complicated trip exclusions, which depend on the type of signal at the starting point of the selected route. For example, there is the case that routes should be adjustable from entry signals to exit signals, but not beyond the exit signals. Furthermore, it may be required that, although no routes should be adjustable from track blocking signals to exit signals, they should be able to be set beyond the exit signals. You then only need to provide the transmission of two additional pieces of information via a separate line, one of which is used to transmit the information that marks the starting points with entry signals, while the other is used to transmit the information that marks the starting points with track blocking signals. In the relay groups that are assigned to the exit signals as destination points of the entrances, a working contact of the receiving relay identifying a starting point with an entry signal can then be switched into the target current branch of the circuit arrangement for route formation and a working contact of the receiving relay identifying a starting point with track blocking signal in the transfer current branch of the circuit arrangement for route formation be. The chain-like further switching of the route relay is then interrupted in the event of the exclusion of the journey in the target current branch or transfer current branch of the circuit arrangement for route formation and the desired route formation does not occur.
Circuit arrangements according to the invention generally enable the exchange of information between relay groups assigned to the individual route elements during route formation.

The separate lines provided in the circuit arrangements according to the invention can be prefabricated and laid firmly in the relay racks. In the case of lane plan signal boxes, it can be used as a separate line one of the parallel ring lines installed in large numbers in the relay racks can be used.

These are considerably cheaper than spur lines. the The relay groups of the starting and destination points can be arranged in any way. One can z. B. unite all relay groups of the start and destination points in one relay frame in the case of smaller interlockings.

But you can also use the relay groups of the starting points in one relay rack and the relay groups of the target points in another relay rack.

Appropriately, one becomes the separate

Lines via a switching group serving for central control tasks at the track plan signal box ^ and set them up there so that they can be separated so that they and the connected relay groups are centrally functional can be checked. On one side of this vector group, for example, to the separate line all relay groups are connected, from which the additional information and on the other hand all travel groups are connected to which the additional Information should be transferable. You can also use the separate line in the central switching group Normally open or normally closed contacts can be switched by route relays, with a selection to that effect make that the transfer of the additional information when pressing one and the same start b / .w.

Destination button only for a certain route type, ζ. Β takes place in the case of a train route or a shunting route.

But you can also make the arrangement so that the additional information from the issuer Relay groups is first transmitted to the central switching group, there is received by a relay that forwards the information to the relay groups intended to receive the information by connecting the separate line with a working contact or a separate line with a separate one. Line turns on voltage and if necessary also nod other effects in the central switching group exercises.

In the following, with reference to FIG. 1 and Fig .:

an example of the circuit arrangement according to the invention explained in more detail.

Fig. 1 shows a section of the track diagram of a table with the switches Wi and Wl, an entry signal ES, a track blocking signal GS, an exit signal AS and the route or signal buttons TI to 7 "4 for selecting the start or destination a driveway;

Fig. 2 shows only the for understanding de

circuits required according to the invention. The relay group RG I is assigned to the button 71 and the entry signal ES, the relay group RG 2 is assigned to the button 72 and the track blocking signal GS, and the relay group RG 3 is assigned to the button 73 and the exit signal AS. A relay group ZP.G for central control tasks is also shown. It can be used to be able to cut the parallel ring lines shown a Mb 1 and a 2/6 2 for test purposes.

The embodiment of the invention relates to the control of slip paths behind exit signals and the creation of travel exclusions for these signals depending on the type of signal at the starting point of the selected route. It is supposed to be the setting of a route from entry signals up to exit signals with activation of a slip path but not beyond the exit signals to be possible. Furthermore, no routes should be from track bus signals to exit signals, but they should be adjustable over it without a slip path.

The parallel ring line a Mb 1 is assigned to the entry signals as a separate line and the parallel ring line j2 / 6 2 is assigned to the track blocking signals. The relay group RG 1 assigned to the entry signal ES as the starting point is at point u 11 to the line <■; Mb 1 connected. At points a 12 and a 13, connections of further relay groups assigned to entry signals are indicated. The relay group RG 2 assigned to the track blocking signal CSaIs starting point is connected to line a 21b 2 at point a 21. There are further connections at points a 22, a 23. Indicated relay groups assigned to track blocking signals. The relay group RG3 assigned to the exit signal AS as the destination point is connected to line a Mb 1 at point 611 and to line 32/62 at point b 21. At points b \ 2. 5 13 and 0 22, 6 23 are connections for others. Extension signals of assigned relay groups indicated.

To set a route from the entry signal £ "5 to the exit signal .45, the buttons Π and T3 are pressed. The button relay contact 1 11 in relay group RG 1 applies voltage to line a Mb 1 and the button relay contact in relay group RG 3 131. If the route is permitted, a route relay (not shown) picks up in relay group RG 3 and closes its contact fa3 \. Now the receiving relay El can respond in the circuit ill and its contact eil in the indicated target branch ZSZ of the track line FZS for the route approval test in the relay group RG 3. This allows the route approval test to continue and subsequently the setting of the selected route in circuits not shown and, with the help of the receiving relay El, also the setting of the slip path will.

An attempt is made to move a route from the entry signal ES via the exit signal AS to through the

To set button 74 selectable target point, the chain circuit for the formation of driving signals in the relay group RG 3 would have to continue to the relay group of the target point via the indicated upper control branch ÜVZ of the track line FZS. The normally open contact c2 \ of the second receiving relay E2 located in the branch ÜSZ, which can only attract when a Glcissperrsignaltaste, z. B. button 72 is actuated, but prevents the derailleur from continuing, so that there is no route setting and the desired trip exclusion is achieved.

When trying to set a route from the track blocking signal GS to the exit signal AS , the buttons T2 and T3 are pressed. The key relay contact / 21 in relay group RG 2 puts voltage on line a2 / b2 ; in the relay group RG 3 , however, the button relay break contact; 32 open so that the second receiving relay E2 remains de-energized. The first receiving relay El also remains de-energized because the line a Mb 1 is only connected to the key relay contacts of the keys assigned to the entry signals. For example, the contact ill of the key 71. Voltage can be applied.

The contacts eil and e21 of the receiving relays El is and E2 in the target current branch ZSZ and in the transfer current branch iVSZ therefore remain open. The chain connection for route formation cannot continue: there is no route setting and the desired trip exclusion is thus achieved. In the other relay groups of exit signals connected to line a 2/6 2 via points 6 22 and 6 23, the associated route switching relays can initially respond during the approval test and close the contacts corresponding to contact fa 32, with the button relays not being actuated In these relay groups, the relays corresponding to the receiving relay E2 also pick up; however, these receiving relays are likewise thrown off in the further course of the route formation when the route connecting relays of these relay groups are dropped, so that they cannot have any effect.

If buttons 72 and 74 are pressed to set the permitted route from the track blocking signal GS via the exit signal 45, the route switching relay in relay group RG 3 picks up and closes its contact / Vj 32. In circuit r 21, a 21. 3 2 / 6 2. 6 21. ί 32. fa 32 picks up the receiving relay E2 and releases the transfer current branch ÜSZ with contact e21. As a result, the chain circuit can continue to run and trigger the route setting without, however, the second receiving relay E2 causing the setting of a slip path. In the other relay groups of exit signals connected via points 622 and 6 23, the second receiving relays can pick up again because of the non-actuated button relays; however, they are also thrown off again when the route connection relay is thrown and can therefore have no effect.
