Description

Method for setting up a closure plan The invention relates to a method for setting up a closure plan for signal boxes, in particular for track plan signal boxes, using a sample track diagram table with relays Dummy table fields and a card punch for punching punch cards.

It is well known that when designing a table for a track diagram interlocking sample track diagram tables with true-to-size table field mock-ups used; on these are symbols of track closures, signals, track sections, Control devices of the route block etc. painted on, so that these table field dummies fully correspond to the table fields of the track diagram table to be set up. the Dummies are inserted into the sample track diagram table by hand. This is how it is possible to train the table according to the geographic location of the train station and at the same time to determine the most favorable arrangement of the operating devices. The track diagram obtained in this way becomes the design of the track diagram table based on.

A locking plan must be drawn up to determine the individual routes in which for each route the switch positions, the signal positions and the exclusions from all other routes indicated and by symbols be determined. Since the establishment of the locking plan extensive experience required, so far only specially trained engineers could be called in; however, errors can occur due to human inadequacies, which the Endanger the safety of the later operation of the system.

When drawing up the closure plan, a distinction must be made between Information that is used for the construction of the system and information that is operational (e.g. for Faults) are necessary, but technically arise by themselves.

The following information is required for the construction of the system 1. z. Description of the route if there are several driving options, 3rd slip path limitation. 4. Intermediate protection points.

The following additional information is required for operation in the event of malfunctions required: 1. Exact description of the route, location of the switches and the flank protection devices as well as the course of the slip path, 2. excluded Routes.

To facilitate the design work to be carried out for the installation of track diagrams, an embodiment is known in which the track diagram table as Rust is formed. In this grate, individual table field dummies are made accordingly inserted by hand into the track system to be set up or the table to be set up.

To relays on the relay racks and connections between the relays as well as to be arranged clearly and space-saving with the track diagram table, In another known device, the relay groups are also based on the track diagram arranged in such a way that the relays and other switching means within of the individual relay group are in series one behind the other.

The invention is based on the object, closure plans of less trained staff and largely automatically set up in less time.

The object is achieved in that in the switching device In the sample track diagram, the course of the individual routes is known per se Way automatically simulated after pressing a start button and a destination button and operational deviations from the route (detour routes) by previously operating switches in the turnout fields of the sample track diagram table are set, and that the switching state established for the respective route the relay in the sample track diagram table by means of rotary selectors, which are operated via cables and plugs are connected to the sample track diagram table, one after the other from all table field dummies is scanned and passed on to the card punch via another cable, the the transferred switching status column by column in one of the respective. Driveway punched the corresponding punch card, the card punch each time after punching a column of cards gives a further pulse to the rotary selector and moves the end of the perforation of a switching state that has been established or in the event of an error display stops automatically. By the method according to the invention considerable manpower can be saved, and errors occur as a result human inadequacies no longer arise, so that the operational safety of the to be built system can be controlled significantly.

Using the exemplary embodiments shown in the drawings the invention is described in more detail below.

The one used in a known way when designing the track diagram table, Sample track diagram M shown in Fig. 7 with scale table field mock-ups At is also used according to the invention for setting up the closure plan. The to it necessary switching means are housed in the table field dummy. Because the normal -Table field surface in consideration of the truthful track diagram not enlarged small relays are used, four of which are relays under a field cover plate can be accommodated. They are sufficient to solve the task at hand.

The connection of the table field dummies with each other is, as with the Aimed for track plan technology, produced by uniform cable connections. she are installed in the lower section of the table. The table field dummies are provided with a plug and the table with sockets. Some fields are 'with keys T equipped, which are needed to form the driveway. In Fig. 1 is circuit-wise shown a possibility to carry out the automatic running-in of a route. As on the track plan of a bar table shown in Fig. 1 on the left. recognizable, is the possibility of driving from the top of the switch to the right generally as Basic position (plus position) of the switch assumed and designated with -I-. This basic position designation however, as will be described in more detail below, it is inexpedient.

By simultaneously pressing the start button A and destination button a in the track plan according to Fig. 1, two search circuits are formed, namely a) via contact A 1 of the start button to the table field of switch W1, from here via contacts WS 1 and FS 1-I-1 to the table field of the turnout W 2 and via contacts WS I and FS 1-1 to the table field of the turnout W4, finally via contacts WS 4 and FS4 + 1 to the table field of the turnout W5 and via contacts WS4 and FS4-1 to the table fields of the light blocking signals LSI and LSII and further to the table field of the turnout W7. In the table field of the turnout W7, the relay FS7- responds and creates a circuit via the contacts FL7 / 1 and FS7-1, the contact a 1 of the destination key and the relay FPa; this holds itself via its own contact FPa1; b) from a contact a2 of the destination button to the table field of the switch W7; from here the circuit can no longer form via the contacts WS7 and FS7-2 to the table field of the light blocking signal LSIII, since the relay is already FS7- in the under a) esp has attracted the written circuits. However, if this circuit was already closed, it is subsequently separated by contact FS7-2 . As a result, only the circuit via contacts WS 7 and FS7 + 1 to the relay FS4 + in the table field of the switch W 4 can ultimately be maintained. By pulling on the relay FS4 +, the circuit to the table section of the switch W 5 described under a) is interrupted by contact FS4 + 1, while the circuit is via contacts FL4 / 1 and FS4 + 2 to the relay FS 1-f- in the table section of the switch W 1 -forms. Here, too, the current path to the table field of the switch W2 is interrupted by contact FS1 + 1 and the relay FPA is energized via the contacts FL1 / 1 and FS1 + 2 and the contact A2 of the start button.

The route search is now complete; the circuits remain in place via contacts FPal and FPA1 or FPa2 and FPA2. If, as shown in Fig. 2, there are different travel options via the switches W 8 and W 9 , the desired route must be determined by a special intervention. This is possible by means of the turnout switches WS, which are attached to the table field mock-ups of the turnouts shown in Fig. 5, 6 and 7.

These turnout switches have three positions, the first corresponds to the entry of the switch in a route, the second of the fixed switch position to the right, the third of the fixed turnout layer to the left.

In the track plan excerpt shown in Fig. 2, only the position of one of the points W 8 or W 9 can be determined by: Operating the switch mentioned manually. The circuits described above then come about automatically.

After the route search has been carried out, the edge protection search is now necessary. Parts of the required circuits are shown in Fig. 3. A contact FPA3 of the relay FPA shown in Fig. 1 initiates the flank protection search for the route that has already been determined. Via the contacts FPA3 and FS1 + 3 z. B. the relay FL 2 assigned to the switch W2; its contact FL 2l1 switches on the relay FS2 +. So that this relay does not trigger a new route search, contacts of the edge protection relays are arranged in the circuit according to Fig. 1. The flank protection search for the switch W 2 is activated by pulling in the relay WÜ1 via the contacts FL2 / 2 and FS2 + 1.

The flank protection search is carried out in the same way from the switch W4 to switch W5.

Since the edge protection search only takes place from the starting point of the route, it is possible to include the light blocking signals in this current route; the "stop" relay HI and the "run" relay FII pick up. The flank protection is given to the switch W7 by the light blocking signal LSIII; therefore the relay FL III picks up and switches on the "stop" relay H III via contact FL 111 1. Its tightening is reported via the contacts FL III 2 and H III 1 by tightening the relay WU7 in the table field of the switch W 7.

Should a flank protection off. operational. Considerations are shortened., The flank protection search line z. B. to relay W Ü 1 are switched through. The edge protection device is therefore not excited.

A confirmation that the route and edge protection are set is then given by activating the signal monitors SU1 and SU 2 shown in Fig. 3. In the circuit of the signal monitors SÜ1 and SÜ2, all relays belonging to the set route are monitored so that the entire route can be recorded on a punch card. All essential parts of the locking plan are created with it.

The described automatic search for a route with flank protection refers to an exit road. When entering, the procedure is analogous, only then a key is used as the destination key, which is expediently outside of the sample track diagram table about in that outer framing is appropriate because in the final Track diagram table this target button, which is the end of an approach path without a slip path is not installed at the actual destination of the route. By switching on the button at the end of the slip route is treated as part of the route; the points of the slip-through path that have been traversed to a point and blunt are thus considered to be traversed Treated points in the guideway. It is thus possible with the sample track diagram table not only the shape of the table field and the appropriate design of the track diagram, but also to finally determine the course of the route. The table is at the service Illuminated only to the same extent as the switches, track sections or signals assigned relay. All other fields are dark. The switching devices in table M can be taken directly from the network via transformers or rectifiers be fed. If a route was set and it is registered by the punch L, so the table is switched off from the mains and the illumination goes out. Then it will be the next route is set.

To register the route information, it is necessary to enter all the designations to be specified in numbers and to dispense with all letters or other identifiers.

Therefore, it is inconvenient to e.g. B. the switch layers with -I- or - to describe. The turnout layers are therefore designated with numbers, namely the plus layer with 1, the minus position with 2, the plus position as a protective switch with 4 and the minus position as a protective switch with 5. For the same reason, the Falirstrasse designation is also used unsuitable with letters; it is formed by track numbers. For the station tracks the numbers 01 to 99 are provided, for the main tracks the numbers from 10'1 on upwards.

The route is named from the start to the finish. An exit from track 9 to track 102 is designated 09-102 and an entrance from track 101 to track 8 is designated 101-08. The turnout names of the single and double crossing turnouts are expediently expressed in numbers in such a way that they are numbered consecutively as single turnouts. A switch with the identification 2a / b is designated with 2, for example, a switch with 2 cld with 3.

In Fig. 4a to 4c it is shown how the position of a switch, the position of a light blocking signal or a track number can be converted into numbers. Has z. B. in the circuit according to Fig. 4a, the contact FL switched over, then the closing of the contact FS1 -f- corresponds to a 4 or the closing of the contact FS1- to a 5. If, however, the contact FL is in the position shown, then corresponds the basic position, i.e. if the switch is not required for the set route, a 0; In the same way, switching over one of the contacts FS2 + or FS2- corresponds to a 1 or a 2. In the circuit according to Fig. 4b for a light blocking signal, the basic position (no relay is required for the relevant route, contacts H2 and F2 are closed) corresponds to a 0 If, on the other hand, the holding relay works (contact H 1 closes), this corresponds to a 1; If the travel relay works (contact F 1 closes), this corresponds to a 2. Track numbers are passed on to the punch via a contact Sii as shown in Fig. 4 c.

These numbers must now be tapped and recorded on the punch card will. The individual circuits are tapped in the one shown in Fig. 5 Way. In the table field dummies At, of which two are adjacent in Fig. 6 are shown again, rectangular plugs St with connections 0, 1, 2, 4 and 5, which correspond to the specified digits of the switch positions, were introduced.

Each connector is connected to a rotary switch Dr with five arms for transmission into the punch. A cable connects the rotary switch Dr to the punch L. The cooperation between the punch and the rotary switch is shown schematically in Figs. The normal operation of the punch, not shown in detail, is as follows: It has twelve buttons. Pressing the button energizes the relay assigned to the button, and a heavy armature penetrates the punched card at the point corresponding to the activated relay. Eighty columns of this card can be punched. The five arms of the rotary switch shown in Fig. 5 and 7 sense the lines coming from the dummy table fields of every turnout, every signal and every track section and the voltages applied are passed on to the punch in the same order. In the punch, the number corresponding to the live, tapped line is punched into the corresponding card column with each tap. If there is a malfunction and several numbers or none are given at the same time, the punch will display a malfunction. The switching of the rotary switch is shown in Figs. 7 and 8. Have. In the sample track diagram table the relays Si = I1 and SU2 of the circuit according to Fig. 3 are working, the contact An, a switch-on button is actuated and the rotary switch is switched via the contacts SÜ11 and SÜ21 through the relay D to the first contact bank. Relay D bridges contact An with contact D 1 and thus remains energized. If the punch has picked up the first current surge and moved the card by one hole width, the rotary switch receives another current surge via contacts D 2 and L 1 on the punch and checks the next row of contacts. Correspondingly, the punch and rotary switch switch automatically step by step.

Are in the eighty-column punch card for the route designation If about six holes are used, there are still seventy-four holes to mark of points and signal positions are available. Has a train station over seventy-four Turnouts and signals, several connection punch cards must be created for a route which are expediently numbered consecutively.

Only one hole punch is required for each table size. He can go to Punch every card to be used. If the eightieth row of the first card was punched, this is indicated by ringing the bell. It becomes the match between Punch and table checked again, and the punch can then be brought into its home position will. The second card can now be inserted into the punch and punched. the The size of the contact bank of the rotary switch is different depending on the design. However, it is automatic switching to the following switches without difficulty possible.

The known tabulating machines are used to evaluate the punch card for the purpose of determining the route exclusions. The punch card (reference card) assigned to the route to be compared is compared with the punch cards of all other routes by adding the numbers in the corresponding columns in the reference card and in each of the cards to be compared. If the reference card contains e.g. B. 0 (no lock for a turnout), there is no exclusion with any other route. A route will only be excluded if the map to be compared has a different turnout location than the reference map. The following table shows the existence or failure of exclusions. Exclusion Reference card Ver gleidzs sum or no 0 (no lock) 0 0 no 1 (turnout left) 1 2 no 2 (point position on the right) 2 4 no 4 (turnout left 4 8 no as protective switch) 5 (switch position on the right 5 10 no as protective switch) 0 1 1 no 0 2 2 no 0 4 4 no 0 5 5 no 1 2 3 yes 1 4 5 no 1 5 6 yes 2 4 6 yes 2 5 7 no 4 5 9 yes As can be seen from the table, the total numbers 3, 6 and 9 indicate the presence of exclusions. In these cases, the map to be compared must be written down by the tabulating machine as a map of an excluded route. This table also shows why the numbering for the switch positions was carried out in the manner described above.

The total number 9 indicates that it is a double safety switch, since this exclusion by simultaneous left position as a protective switch (number 4) and Legal situation as a protective switch (section 3) arises. Consequently, through the tabulator each intermediate switch is also indicated separately. A subsequent, very time-consuming Examination for existing intermediate protection points can therefore also be omitted.

The embodiment described was the case of a central interlocking based on. However, it is possible with the method according to the invention too to draw up any other closure plan ..
