Description

Circuit arrangement for storing control orders for routes according to age group The invention relates to a circuit arrangement for storing and placing of orders for routes according to age groups according to the Order of input in the switchboard, in which the routes go through Pressing start and finish buttons can be selected.

In the railway safety system there is often a requirement for local or remote-controlled interlocking systems, commands for routes and commands, Consents or the like to be able to save and the stored orders by reporting devices to display. Such storage devices have hitherto been preferably used in interlocking systems used in which the operations are carried out according to a specific program be e.g. B. in sequence systems for setting switches or routes for the wagons running in a certain order. The storage facilities exist from several memory levels of the same structure and connected in series, in which the required memory switching means for each planned control order, z. B. the start and / or destination points arranged relays are arranged. The storage levels save the standing orders in the order in which they are entered by pressing Start and finish buttons in a switchboard is triggered.

By exclusion means, e.g. B. Contacts of the storage relay is this ensures that only one control order is stored in each storage level can be. In the case of automatic operation, the actuating orders are based on the last one Storage level necessarily by age level in the order in which they are entered Activation of the corresponding control relay carried out and then deleted. The other stored actuating orders then automatically move to a storage level each Further.

For interlocking systems in which standing orders for train journeys by several Main tracks can be saved after several station tracks or vice versa should result when submitting these positions according to age groups for a fast and smooth operations processing various disadvantages.

Is, for example, the submission of a stored command Not possible for a certain route because a station track is still occupied is, the control orders given later can with the previous storage facilities for further routes to other station tracks are also not carried out. The sequence specified by the age groups can then only be changed through intervention can be changed by hand.

There is a further disadvantage of the known storage devices in the high cost of memory switching means, since at least as many memory stages the maximum number of jobs that should be saved at the same time are required.

The invention is based on the problem of this high expenditure To restrict memory switching means and the placement of standing orders as far as possible in accordance with the constantly changing driving options during operation, that the order according to age group is retained for such jobs, which concern the same starting and / or destination point.

According to the invention, each storage stage is used to control the storage relay one modeled on the track system and with at least one test relay in front of each Storage process checked test current network assigned, in the exclusion contacts the storage relay only interrupt those circuits, from or to whose assigned track has already been assigned an actuation order. Through the contacts the storage relay of a storage stage in the associated test current network is ensured, that for each start and / or destination point of the track system there is only one control order can be stored in one and the same memory level, but also in the same storage level, further actuating orders can be saved, the other Relate to start and finish points. The Contracts are placed taking into account the respective feasibility. However, the age sequence remains the same starting and / or destination point relevant orders received.

An exemplary embodiment of the invention is shown in FIGS. 1 to 5 explained.

1 shows schematically a track bidding table arranged in a command center for a track system in which the main tracks a and b are connected to the station tracks u, v and w via the switches W1 to W5. Each of these tracks is assigned a track button Sa, Sb, Zti, Zv or Zw, which are used in the usual way as start and destination buttons. If control orders for the access roads from the main tracks a or b are to be stored in the station tracks u, v or w gel, the starting point and destination are marked by pressing these track buttons.

FIGS. 2 to 5 show the circuit arrangement of a two-stage memory device. FIGS. 2 and 3 belong to the first and FIGS. 4 and 5 to the second memory stage. A storage relay is arranged in each of these two storage levels for each adjustable route. So are z. B. the memory relays AU1 and AU2 of the route au, the memory relays AVI and AU2 of the route av, the memory relays AWl and AW2 of the route aw, the memory relays BU1 and BU2 of the route bu, etc. The relays Lal and Lbl or Lag and Lb 2 control the sending of a stored control order to the next storage level or, in the case of the last level, the implementation by the control relay and then delete the order in its own storage level. The relay contacts are labeled with the designation of the associated relay and the appended numbers 1, 2, 3, etc.; For example, among the memory relay AU 1 and BU 1, the contacts AU11 to AU15 and BU11 to BU15 to the memory relay Ah1 and Bhl the contacts AH11 to AL'15 and BH11 to Bh15 or to the memory relay AW1 and BWl the contacts AWll to AW15 and BWll to BW15.

Each storage stage is assigned a test current network, shown in FIG. 2 or 4 and simulated on the track system, which is checked by the test relays Pab or Pa2 and Pb2 before each order is stored. These test relays are assigned to the lowest number of available track types, in the case shown, the mainline tracks. In the test current network shown in FIG. 4 for the second storage stage, a test relay Pa2 and Pb2 is provided for each track a and b. These test relays control the connection circuits of the storage relays AU2 to BW2 of the second storage level with one contact each Pa22 or Pb22. For the test current network assigned to the first memory stage and shown in FIG. 2, only one common test relay Pab is provided for both track tracks a and b . This is possible because the storage relays AU1 to BW! the first memory stage contacts Sag and Sb2 of the track keys Sa and Sb or, respectively, the key relays controlled by these keys, not shown, are arranged. For these keys or key relays there are mutual exclusions in a known manner, which prevent the simultaneous actuation of these contacts.

If, for example, the route setting order for the entry from the main track a into the station track v is to be saved, the track buttons Sa and Zv are actuated and their associated contacts Sai and Sag as well as Zvl to Zv3 are closed. In Fig. 2, the response winding 1 of the test relay Pab is excited in the circuit Pab - Sa 1 - Lall - AV11 - Bh11 - Zv 1, so that this relay picks up and changes its contacts Pabl to Pab5. The test relay Pab closes its contact Pab 1 in the circuit of its holding winding 2, in which it is via the contact TP 1 of a button test relay, not shown and switched off when the buttons Sa and Zv are pressed, until the button test relay responds again, i.e. until the buttons Sa and Zv are released remains on. In Fig. 3, the memory relay AVI is switched on via the test relay contact Pab 2 and the button or button relay contacts Sag and Zv2. This changes its contacts Ah11 to Ah15. The contact AV11 interrupts the circuit of the test current network assigned to the track v, so that the storage of further control orders for entrances to the station track v is temporarily ruled out. The response winding 1 of the relay La l is switched on via the contact Ah12, which is assigned to the entire group of entrances from the main track a into one of the station tracks. Through the contact Sag of the track button Sa in the response circuit of the storage relays AU1, AV1 and AWl and through the parallel connection of the contacts AU 12, Ah12 and AW12 of these storage relays, it is achieved that the relay Lal for each track a and one of the station tracks u, v or w involved standing order. The relay La l actuates the contacts Lall to La 13 when it is triggered. A self-holding circuit for the storage relay AV1 is closed via the contacts La 12 and Ah13. Instead of a common winding for the switch-on circuit and the self-holding circuit, the storage relays can also each be assigned a response and a holding winding. The circuit corresponding to track a is interrupted by the contact La 11 in the test current network of the first storage stage (FIG. 2). As a result, the storage of further control orders pertaining to track a is blocked until relay La 1 is reset, ie until the control order set in the first memory stage is deleted. Instead of this contact Lall, contacts of the storage relays AU 1, AVI and AW1 connected in series can also be arranged.

By closing the contacts AT114 and AV15 in the test current network of FIG. 4 for the second storage stage or in the connection circuit of the storage relay AV2 in FIG. The test current network of this stage is switched on after the buttons Sa and Zv are released, the button test relay (not shown) responding again, contact TP 1 opens in FIG. 2 and contact TP2 closes in FIG. 4. The test relay Pab of the first storage level is switched off by the contact TP1. In order to check whether this relay has dropped out, the contact Pab4 is arranged in the test current network of the second storage stage in FIG. As soon as the contacts TP2 and Pab4 are closed, the response winding 1 of the test relay Pa2 is excited in the circuit TP2-Pa-La21-Pab4-AV14-AT121-BV21. The contact Pa21 is closed, so that the holding winding 2 of the relay Pa2 is also excited via the already closed contact La 13 of the relay La 1 . At the same time, the storage relay AV2 responds via the contacts Pa22 and AVIS , switches on the relay Lag via its contact Ah22 and closes its self-holding circuit via the contacts AV23 and La22. The steep order has now been transferred to the second storage level. The contacts AV21 and La21 arranged in the test circuit of this storage stage ensure in turn that further control orders relating to the main track a and / or the station track v cannot be transferred to the second storage stage.

The transferred standing order is deleted in the first memory stage after the test relay Pa2 and the relay Lag have responded, since then in FIG. 3 the discharge winding 3 of the relay La 1 is briefly switched on via the contacts Pa23 and La23. The relay La 1 drops out again and brings its contacts Lall to La13 back into the position shown. The contacts La 12 and La 13 interrupt the self-holding circuit of the storage relay AVI and the test relay Pa2, so that the contacts of these relays also assume the position shown. This frees up the first storage level for receiving further control orders, namely, since the contacts A111 and Lall are now closed again, also for those relating to tracks a and / or v.

If an order is now given for the entry from track b into station track u by pressing the Sb and Zu buttons, this order is also sent from the first to the second storage level, since it does not affect either track a or track v. The same would also apply to the order for an entry from track b into track w . Saving takes place in the same way as with the first control order, i.e. by closing the button-controlled contacts Sb 1 and Sb 2 as well as Zu 1 to 3 or Zw 1 to Zw 3. For example, when the track buttons Sb and Zu are pressed, the test relay Pab in the circuit Pab3-Sb2 speaks -Zu3-BU1 on. Then the storage relay AU1 in the circuit Pab3-Sb2-Zu3-BU1 is switched on. The storage relay BU1 operates its contacts BU11 to BU15, so that the relay Lb 1, which is jointly assigned to the group of entrances from track b to track u, v or w, picks up and the latching circuit Lb12-BU13-B @ T1 is closed. In Fig. 2, after releasing the buttons Sb and Zu by the contact TP 1, the test relay Pab is switched off. This closes its contact Pab 5 in FIG. 4, so that the test relay Pb 2 in the circuit TP2-Pb2-Lb21-Pab5-BU14-AU21-BU21 responds via its winding 1. It closes its self-holding contact Pb 21 in the circuit of its holding winding 2 and the contact Pb 22 in the response circuit of the storage relay for the second storage stage. The storage relay BU2 now receives power via the contacts Pb 22 and BU 15; the part of the test current network assigned to track u for the second storage stage is interrupted by the contact BU21. Relay Lb 2 responds via contact BU22, which interrupts its contact Lb 21 in the response circuit of the test relay Pb 2 and, with its contact Lb22, closes the self-holding circuit Lb22 - BU23 - BU2 for the storage relay BU2. The command for the route from track b to track u has now been transferred to the second storage level. When the relay Lb2 responds, the discharge winding 3 of the relay Lb 1 is switched on briefly in FIG. 3 via the contacts Pb 23 and Lb 23. When it drops out, this relay Lb 1 with its contacts Lb 12 and Lb 13 interrupts the self-holding circuits of the storage relay BU1 or of the test relay Pb2. This also deletes this job in the first memory level.

In a similar way, when other control orders are stored in the second memory level, the memory relays AU2, Bh2, AW2 or BW2 respond, which establish a holding circuit via their contacts AU23, Bh23, AW23 or BW23 and the contacts La22 or Lb22, with their contacts AU21, BTT21, AW21 or BW21 interrupt the test current network shown in Fig. 4 and switch on winding 1 of the relay Lag or Lb2 with its contacts AU22, BT122, AW22 or BW22.

As long as the contacts La21 and Lb21 are open in the test current network of the second storage stage, no further actuating orders can be received from this storage stage. On the other hand, it is possible to save as many positioning orders in the first memory level as there are track tracks. These positioning orders must also relate to various station tracks; however, it is possible to save them, regardless of whether an order for a route to the same station track and / or from the same main line is already stored in the second memory level. The first storage level then first forwards that actuating order to the second storage level for which the corresponding test circuit is closed first. In this way, the second or, in the case of even more storage levels, the last storage level always contains the actuating order given first in terms of age for a specific starting point and / or destination. In the selected example, it can also contain a further control order that does not concern the same starting and / or destination point as the first order. This has the operational advantage that the routes can be set as much as possible in accordance with the operational requirements. For example, if the station track v is still occupied, so that the first stored command for the entry from track a to track v cannot be submitted for the time being, the free route from track b to track u can already be set and the corresponding train journey can take place.

To send the stored control orders, for example, contacts of the storage relays of the last storage level can be arranged in the selection circuits of the route setting relays. Then the route in question is automatically set. But it is also possible to set off a control order from a key operation, z. B. to make dependent on the actuation of the corresponding track buttons, which are arranged within the track diagram of a caretaker's table. In both cases, the deletion of the relevant control order in the last memory level can be conveyed, for example, by corresponding signal control relays (not shown) or similar relays, which briefly switch on the discharge winding 3 of the relay Lag or Lb 2 with their contacts SA1 or SA2 shown in FIG .

In order to ensure the placement of the actuating orders according to the operational possibilities by pressing start and destination buttons arranged in a track diagram setting table or the like, it is advisable to assign signaling devices to each start and / or destination point which display the actuating orders contained in the last storage level. In the attendant's desk shown in FIG. 1, the reporting devices Ma and Mb are assigned to the route track buttons Sa and Sb, and the reporting devices Mu, Mv and Mw are assigned to the station track buttons Zu, Zv and Zw. For the order entered in the second or last storage level to set the entry from track a to track v, the reporting device Ma at the starting point then shows an identifier of the destination, ie the station track v, and / or the reporting device Mv at the destination shows an identifier of the starting point , ie the main track a. For this display, for example, illuminated transparencies with the letters a and b or u, v and w can be used. According to the entrance of the track would be for the included also in the second memory stage contract for points b to track and the signaling device Mb, the indicator for the track and the signaling device and Mu illuminated the flag for the track b. The keeper is now free to either implement the orders according to the real age group, which can be seen from the order in which the labels appear, or if the oldest order cannot be executed, the second oldest order can be executed first. If the orders displayed are routes that are not hostile to each other, both can even be set practically at the same time.

These operational advantages are also with such interlocking systems present, in which the memory switching means automatically switch to the route switching means act. In these cases, those in the last memory level are always used Fixed standing orders are placed first, their routes cleared first are. Every turnout is used for setting, defining and dissolving routes assigned to the required switching means, the respective standing order can already after driving on and clearing a switch, an intersection or the like.

Another economic advantage arises from the fact that with a limited number of memory switching means a significantly larger number of actuating orders than before can be stored. While only s standing orders could be stored in the previous memory devices with s memory levels, the result of the memory device according to the described embodiment of the invention is a number of n # s storable actuating orders, if n is the number of main tracks. If the test relays were assigned to the station tracks, m # s standing orders could be stored if m is the number of station tracks.

The application of the invention is not limited to storage devices, as shown in FIGS. 3 and 5. For example, it can also be used for the first Storage stage a test current network with a test relay assigned to each track be used.

In the test current networks and connection circuits of the storage relays switching means for storing setting orders for partial routes can still be used, Detour roads or the like. Be taken into account.

For track systems in which train journeys or routes between n main tracks and m station tracks take place via v intermediate tracks, test relays can also be assigned to the intermediate tracks if v is equal to or smaller than n or m . If the routes are selected by buttons for the start and destination points of partial routes, it is expedient to also assign reporting devices for the start and / or destination points of the partial routes to these buttons.

In the practical application of the invention, it can also be advantageous to provide separate devices for the direction of travel display in the track diagram and to arrange contacts that are dependent on the direction of travel in the test circuits of the storage stages. To take back stored control orders, further switching means, e.g. B. cancel buttons, are arranged, by pressing all or only one of the control orders are deleted. For this purpose, for example, in the circuits of the drop windings 3 of the relays La 1 and Lbl or Lag and Lb2 controlled by return and track keys contacts can be arranged, which to the contacts Pa 23 and La23 or Pb 23 and Lb 23 or SA1 or SA2 are connected in parallel.
