DE1530387B1 - CIRCUIT ARRANGEMENT FOR DRAIN SYSTEMS - Google Patents

Description

The invention relates to a circuit arrangement for sequencing systems in which the points are automatically set according to the multi-digit binary sequence code contained in a train memory, in which each decimal direction track number is provided as sequence information with the aid of a punched tape that can be scanned in both directions according to the telex code CCIT 2 in the train memory is entered clock-controlled.

In such automatic drainage systems, it is known that a drainage mountain is used in addition, wagons or groups of wagons of a train, called departments for short, over a through To distribute the track branching system in different direction tracks. The setting of routes for the individual departments is achieved by that a train store is provided in the associated control box. In this train store are by pressing the buttons to reach the respective direction track or process information required for the associated route for placement of the turnouts and form the sequence program. Arrange the departments in the order of running by operating a track switch that the Train memory the sequence information for setting the points for the relevant one Department submits the route specified by the direction track number.

It is known to use a punched tape to store the entire sequence program to be used in conjunction with a teletypewriter (German patent specification 1008 346). The process information for the individual departments is issued directly from the punched tape. A plus-minus keyboard is used to produce the perforated tape provided in a combination of five, which allows for a track system with up to to five switch tiers according to the respective process information punch the associated code holes of the sequence code in the punched tape.

However, this storage method and control has the disadvantage that on the punched tape only expiry information for a maximum number of 32 directional tracks can be provided. In most cases, the track systems point to the drainage mountains however, there are significantly more directional tracks. There is also the difficulty to be able to change the program stored on the punched tape if necessary, when the processes have already started without disrupting the process.

Furthermore, there is a circuit arrangement for sequence systems with program control known (German Patent 1063 198), in which switching means are provided; by actuating them, the point setting commands controlled by the punched tape are suppressed, changed and / or supplemented by additional commands. This circuit arrangement is not suitable for systems where the process information is not direct from the punched tape, but from the train memory.

The invention is based on the object of creating a circuit arrangement for automatic sequence systems with which it is possible, in particular, to enter multi-digit direction track numbers as sequence information, which are present on the teletype code CCIT 2 on the punched tape, into the train memory and at the same time from the Recode the teletype code into the sequence code. Since the punched tape can be produced at the same time as the shunting slip, which is required anyway, on the teleprinter, the production of the punched tape does not require any additional expenditure of time and effort. Above all, by avoiding manual entry of the process information using keys in the train memory, errors and mix-ups are excluded. If the direction track numbers converted according to the telex code are provided on the punched tape instead of the sequence information, the above-mentioned difficulty does not arise that such automatic controls are only available in sequence systems with five switch relays, i.e. only 32 direction tracks, corresponding to the five code holes of the CCIT 2 code can be applied.

The directional tracks are the same for most runway systems labeled with two-digit numbers. That means that each is over the punched tape Sequence information to be entered into the train memory as the direction track number consists of a code word with two rows of code holes of different values. At least Another row of code holes can be added if the departments have an option special identifier is to be assigned. It is therefore the object of the invention Furthermore, the circuit arrangement is designed in such a way that it is independent of the scanning direction the multi-digit code words correctly into a multi-digit code word of the sequence code are implemented and the special characteristics are recognized. Since the Train storage according to modern technology, mostly in electronic circuit technology are carried out, this circuit arrangement should also be based on such a technology be designed. The electronic circuit has opposite the equally possible Relay switching the well-known advantages of contactless control.

This object is achieved according to the invention in that at least one after each transport of the perforated tape from one row of holes to another Position depending on the code word of the telex code Continuous circulation counter is provided, the positions of which correspond to the positions of the direction track numbers are assigned and for each position one is provided for the relevant position Code converter to convert the digits of this position from the telex code into the Sequence code switches.

According to a development of the invention, it is advantageous that for every cycle counter except for the positions assigned to the positions of the direction track number at least one further position is provided, the detection of which is activated and implementation of additional indicators takes place.

A preferred advantageous arrangement that allows the punched tape to scan either in one direction or the other is to be followed by another Embodiment of the invention characterized in that for each scanning direction a separate circulating counter is provided and the positions of one circulating counter to those of the other the digits of the direction track numbers and the additional ones Identifiers are assigned in reverse order.

A. Embodiment of the invention is explained in more detail below with reference to the drawing. It shows FIG. 1 the track diagram of a drainage system, F i g. 2 in the left part different code words for digits and characters of the telex code CCIT 2 and in the right part the direction track numbers of the sequence system with the respective code words of the sequence code, FIG. 3 a to 3 c an arrangement for scanning punched strips and converting the sequence information available as direction track numbers in the telex code into the sequence code for the sequence system selected in the example.

The drawing shows in FIG. 1 schematically shows the track diagram of a drainage system, in which all departments running down from the drainage hill AB can be routed via six switch tiers A, B, C, D, E and F into the zone of the directional tracks. The switch scale C contains four switches W 3, W 4, W 5 and W6, via which the direction tracks 31 to 38, 41 to 49, 51 to 59 and 61 to 68 can be reached.

In the right part of FIG. 2 these direction track numbers are with the associated code words of the sequence code are listed in a table. Basically two-digit directional track numbers are provided for all direction tracks. That has the advantage that a converter circuit is always used for each direction track number a constant number of two consecutive digits in a code word of the sequence code must implement. Each code word of the sequence code consists of the number of Six turnout tiers made up of six code elements, the first of which is the turnout of the turnout tier A, the second are assigned to the two turnouts of the turnout scale B and so on. By a fixed assignment to the binary information content of these code elements the turnout layers in the respective turnout scale is given for each department Direction track number determines the runoff route. To reach the direction track 31, all turnouts of the individual turnout tiers located in the drainage path are accordingly brought the code sign intended for this direction track into the legal position.

In the left part of FIG. 2 shows a table with code words of the telex code CCIT 2 for the digits 1 to 0 and the characters Pkt and Zwr. All points mean a code hole in the punched tape. Those code holes which are listed in a common column in this table are removed by the same scanning device A 1, A 2 to A 5 (FIG. 3 b).

The structure and mode of operation of the circuit arrangement according to FIG. 3 a to 3 c for converting the sequence information present as direction track numbers in telex code on a punched tape into the sequence code are explained below. Before inserting the tape into a tape scanner, z. B. checked on the basis of the shunting slip, in which order the departments of a train to be dismantled will leave the mountain. If the sequence information of the first division is at the beginning of the paper tape, i.e. if the corresponding code word begins with the tens digit, then a switch RS (Fig. 3a) must be brought into the position shown for forward scanning of the paper tape. After the appropriate insertion of the perforated tape, the paper contact Pk is closed and the contact AK is moved from the illustrated basic position “Off” to the other position. In the punched tape scanner, the punched tape is moved step by step by a Vorsc'hubmagneten VM on the scanning devices A 1 to A 5; z. B. contact brushes, moved past. When scanning code holes, circuits are closed that control a code converter. The feed magnet VM for the transport of perforated tape is controlled indirectly by clock pulses n, which a clock distributor emits from the tension store (not shown). Via a frequency divider FT , pulses are generated in a relatively slow cycle sequence at a cycle time determined by the clock distributor: which, through an AND circuit K6, advance a three-stage circulating counter U1, to whose upper outputs a bistable multivibrator S is connected. This tilting stage is controlled at regular time intervals from the basic position shown to the other stable position and back and supplies the control current for the feed magnet VM. In the time between a pulse from the upper output of the circulation counter U 1 and a pulse from its middle output, the feed magnet is switched on and transports the tape by one step or one row of holes. During the rest of the time, i.e. until another pulse is emitted from the upper output of the circulation counter U1, the punched tape stands still. This ensures that the transport only happens when no conversion is in progress.

When the last position III is activated, the circulation counter U1 emits a control pulse via its lower output to, among other things, a bistable multivibrator S1. This goes from the basic position shown to the other position. Due to the clock pulse from the clock distributor, which follows the pulse output via the lower output of the circulating counter U1, the flip-flop S1 is reset to its basic position and emits a pulse that is effective for the AND circuit K1, which only passes it on if at the same time control potential is output by at least one of the OR circuits M1, M2 and M3. These OR circuits are connected to the contact brushes A 1, A 2, A 4 and A 5 (FIG. 3 b) via several lines L 1. With all code words of the punched tape, except for the one for the space character Zwr, at least one of the lines behind the scanning brushes is live, so that when: these code words are scanned, the AND circuit K1 prepared by the flip-flop S1 emits a pulse . With this pulse, one of the two three-stage circulation counters U2 or U3 is incremented via the OR circuit M4, in this case the circulation counter U2 as a result of the position of the switch RS. Via the OR circuits M5 and M6, these circulating counters cause the AND circuits K10 to K50 and K31 to K51 connected to the lines L 2 to be activated.

Each of these circulation counters U2 and U3 has three positions, of which the position Z the tens of the direction track numbers, the position E, the One digits of the direction track numbers and the position W an additional identifier assigned to each direction track number. The one when scanning the perforated tape backwards Activated circulation counter U3 differs from the circulation counter U3 in that that its positions opposite those of the other circulation counter the positions of the direction track numbers and the additional identification in reverse Order are assigned. In principle, it would also be possible and advantageous only a circulation counter, e.g. B. U2 to use the direction of advance set as a function of the respective scanning direction of the perforated tape will.

When the OR circuit M4 emits a pulse, the circulation counter U2 gives the opening potential to the AND circuits K31, K41 and K51 via the OR circuit M5 on the upper line L2 in position Z. The circulation counter U2 is incremented from position Z to position E. When switching from position E of the circulation counter U2 to position W , the AND circuits K10, K20, K30, K40 and K50 receive opening potential via the OR circuit M6. When the position W is activated, circuit parts are prepared that enable the additional identifier to be recognized and evaluated. The voltages applied differently to the AND circuits K31 to K51 or K 10 to K50 via contact brushes A 1 to A 5 result in different output signals when the AND circuits are controlled by the circulation counter U2 or U3, depending on which Code word is being scanned on the punched tape. With the help of these AND circuits are a plurality of logic circuits and lines L 8 through L 13, various memory AS, BS, CS; DS, ES and FS, which correspond to the in FIG. 1 indicated switch series A to F are assigned, controlled from the basic position shown in the other position. They then give opening potential to an assigned AND-SC circuit AK, BK, CK, DK, EK or FK. The other connections of these AND circuits are connected via lines L6 and L7 and the AND circuits XK and XK1 to the bistable multivibrators XS and XS1 that the AND circuits AK to CK in prepared multivibrators XS or XS 1, the AND -Circuits DK to FK can only be opened with a prepared flip-flop XS and the AND circuits DK1 to FK1 can only be opened with a prepared flip-flop XS1. If one of the AND circuits AK to FK or DK1 to FK1 is open at both inputs, the relevant AND circuit sends a code character to the train memory (not shown) for a position in the sequence information after the sequence via the associated output line AL to FL. Code.

The memories MS1, ES 1 and FS1 connected via the lines L 14, L 15 and L 16 as well as the two bistable multivibrators XS and XS 1 with the associated AND circuits XK and XK1, the framed part of logic circuits and the AND circuits DK1 , EK1 and FK1 are provided because the in F i g. 1 has no symmetrical track network 'shown as an example. For example, only eight directional tracks 31 to 38 or 61 to 68 are reached via switches W 3 and W 6 of switch relay C, while switches W 4 and W5 reach nine directional tracks 41 to 49 or 51 to 50, since only behind the last-mentioned turnouts in the turnout scale F are followed by a turnout W4, 56 or W5, 89. Furthermore, the switch W4, 56 leads to the fifth or sixth directional track, whereas the switch W5, 89 leads to the eighth or ninth directional track of the respective directional track group. On the other hand, in all groups of directional tracks, these are numbered consecutively, which makes it necessary that the same digits of the one-digit indicated on the punched tape have to be converted differently. This is achieved in a simple manner by code converters in connection with the above-mentioned logic circuits, which convert the units digits as a function of the associated tens digit, regardless of which scanning direction of the paper tape is selected.

If the tens digit scanned first from the punched tape is 6, the lines behind the contact brushes A 1, A 3 and A 5 are live - see left part of FIG. 2 - so that the AND circuits K31 and K51 prepared for this tens digit each emit a pulse to the downstream logic circuits of the converter. The pulse from the AND circuit K51 sets the memory AS from the basic position shown to the other position via a delay element and the line L 8, and the pulse from the AND circuit K31 does the same via an OR circuit M9 and the line L9 at storage BS. This means that the part of the sequence information that is directly dependent on the tens digit 6 is temporarily stored in the sequence code for forwarding to the train memory.

With the preparation of the AND circuits K31 to K51 for the tens digit At the same time, the blocking gate K7 receives control potential. Since at number 6 the AND circuit K41 does not emit a pulse, the locking gate K7 controls the bistable Tilting stage XS from the basic position shown into the other stable position. Would have If the digit 4 was present instead of the tens digit 6, this would only mean the bistable flip-flop XSl has been brought into the other position.

When the perforated tape is further scanned, the units digit is scanned and converted. As already described for the tens digit, a pulse acts after the perforated tape has been transported by a row of code holes on the counter U2, so that a pulse is sent from the output of position E via the OR circuit M6 to the AND circuits K10 to K50 who prepares this. It is assumed that an 8 is present as the ones digit, for example. Then the lines behind the contact brushes A 2 and A 3 are live , so that the prepared AND circuits K20 and K30 each emit a pulse. The pulse from the AND circuit K30 acts via a delay element, inter alia, on a blocking gate K11. Since the negated input of this gate does not receive a pulse from the AND circuit K50, the blocking gate Kll emits a pulse via the line L10, which sets the memory CS from the illustrated basic position to the other position.

The pulse from the AND circuit K20 controls a delay element, inter alia, a blocking gate K12, which, because in this case no pulse is emitted from the AND circuit K10, a pulse via the OR circuits M10 or M11, the lines L 11 or L12, which controls the memory DS and 8S from their basic position to the other position. This completes the scanning of the direction track number 68 in the telex code on the punched tape and its conversion into the down [up code. The code characters of the code word of the sequence information for the same direction number 68 are according to the sequence code in the table in FIG. 2 on the right 111110 and are temporarily stored in the memories AS to FS until they are entered in the train memory.

The third position W of the circulation counter U2 is assigned to the additional identifier, e.g. B. the indicator that a department is to be weighed by a built-in scale below the summit of the discharge mountain. This code, for which the point Pkt is selected as the telex code, is referred to below as the weighing code.

The circuit arrangement is set up so that the weighing indicator is implemented in two possible cases, namely when it is on the punched tape immediately or with the distance of the space character Zwr after the ones digit is provided. The further operation of the circuit arrangement is intended for .this Cases and in the event that the weighing code is missing are described below will.

If the weighing indicator immediately follows the unit digits, the generation of the next pulse for incrementing the circular counter U2 does not differ from the previously described mode of operation. When the code word for the weighing indicator Pkt is scanned, the lines behind the contact brushes A 3, A 4 and A 5 are live (see left table in FIG. 2 "Pkt"). As a result, the memory S6 is controlled from the illustrated basic position into the other position via the AND circuits K9 and K5. At the same time, the locking gates K2 and K4 are blocked, so that the resetting of the bistable flip-flop S5 - it is controlled when switching from position E of the circulation counter U2 from the basic position to the other position - by the AND circuit K 3 at the control pulse from the output of Position III of the circulation counter U 1 remains ineffective.

The pulse from the output of position W of the circulation counter U2 acts via the OR circuit M7 on the bistable multivibrator S3 and controls it from the basic position into the other position. After the perforated tape has been transported on, following the row of holes in the code for the weighing number, the space character Zwr is scanned. The AND circuit K3 receives opening potential at the upper input because the contact face A 3 finds a code hole on the punched tape. At the following control pulse from the output of position III of the circulation counter U1, the AND circuit K3 emits a pulse which only switches the flip-flop S3 back to the basic position because the flip-flops S4 and S5 are already in the basic position. As a result, the flip-flop S3 emits control potential, from which the memory S6 is switched back to the basic position, whereby the weighing indicator is transferred to the train memory. The control potential of the flip-flop S3 continues via the line L3 to the AND circuits XK and XK1, of which ---- as described above - only the AND circuit XK is prepared by the associated flip-flop XS. This AND circuit thus emits a pulse via the line L 6 to the AND circuits AK, BK, CK, DK, EK and FK. Since all of these AND circuits except for the last one from the associated memories AS, BS, CS, DS and ES receive opening potential, the sequence information after the sequence is used as code characters via each of the output lines AL, BL, CL, DL and EL. Code a "1" sent to the train memory and a "0" over the line FL.

If the one digit is first followed by the space character Zwr on the punched tape, the bistable flip-flop S5, which was previously switched from the basic position to the other position, is reset to the basic position by the AND circuit K3. The blocking gate K4 is not blocked by the AND circuit K5 and sets the trigger stage S4 from the basic position to the other position via the delay element connected downstream.

The control pulse from the output of position III of the circulation counter U1 does not trigger a pulse in the AND circuit K1 to advance the circulation counter U2, since there is no opening potential on the upper input of the AND circuit K1 because of the space sign Zwr. After the perforated tape has been transported on, the code word of the weighing indicator Pkt is scanned. Then the memory S6 for the weighing indicator Pkt is set via the AND circuit K5 and the flip-flop S4 is reset to the basic position at the following control pulse from the output of position III of the rotary counter U1 via the AND circuit K3. The output signal emitted by this is not processed further, since the OR circuit MO receives control potential from the AND circuit K5 at its negated input. However, as a result of the last-mentioned control pulse from position III of the circulating counter U1 and the live lines of the OR circuit M3, the circulating counter U2 is incremented in the manner already described. The following functional sequence has already been explained above.

If no weighing code is provided after the units digit is, the space sign Zwr is used instead. Then the switching processes run up to the first space indicator after the units digit as already described away. After the perforated tape has been transported and the following space mark is scanned Zwr is with the control pulse from position III of the circulation counter U 1 over the AND circuit K 3, the flip-flop S4 returned to the basic position. The output signal this flip-flop S4 reaches the then unlocked OR circuit MO Flip-flop S2, which was previously from the pulse from the AND circuit K1 from the basic position was placed in the other position, and sets the tilting stage S 2 back to the basic position return. The pulse emitted by flip-flop S2 switches via the OR circuit M4 continues the circulation counter U2 from position W to position Z. That’s the Sampling of complete process information with the associated space characters, which on the punched tape in each case of this embodiment a space of occupy four rows of holes, completed.

When the following sequence information is scanned, which in turn begins with the When the tens digit begins, a reset signal is generated by the OR circuit M8 via the line L4 given to the memories AS to FS, DS1 to FS1 and the flip-flops XS and XS1, that restores their basic position.

The pulse emitted when resetting the flip-flop S3 via the line L 3 is also used as an incremental pulse for an input register of the train store, in such a way that the train store is only incremented shortly before the following sequence information is entered. This ensures that the sequence information previously entered into the train memory can be continuously queried until the next one is entered and can be made visible on a display board. A separate reset pulse is generated when the switch AK is opened (in the position shown) and passed on to the line L 4 via the line L 5 . This ensures that after the perforated strip has passed through, all storage and tilting stages are in the basic position.

How the circuitry works when converting other process information is immediately clear from the description so far, so that for all this required circuit parts no reference numerals are provided.

The circulation counter U3 is switched on for the backward scanning of the perforated tape. If the weighing indicator Pkt is present in the first sequence information, then when it is scanned, the circulation counter U3 is incremented from position W to position E and outputs a pulse to locking gate K2. However, since this gate is blocked via the AND circuit K5 - this simultaneously sets the memory S6 - the pulse emitted by the circulation counter U3 is not processed any further. Therefore, the space sign Zwr following the weighing indicator Pkt has no further effect.

If no weighing indicator is provided for the relevant sequence information, the space symbol Zwr is used instead. In this case, no pulse is yet emitted via the OR circuit M4 to increment the circulating counter U3 from position W to position E, whereby the counter remains in position W. Since a pulse from the output of position E of the circulation counter U3 (by switching from position A to position Z) is required to activate the AND circuits K10 to K50 for the units digit following the following space character, the circulation counter U3 must then be used twice be advanced one after the other. This is achieved in that the impulse from the output of the position W via the then unlocked locking gate K2 is delayed via the then unlocked OR circuit MO and resets the bistable multivibrator S2 in the basic position. This flip-flop emits a pulse via the OR circuit M4 to advance the cycle counter U3 again.

After scanning and converting the units digit, the pulse takes place from the output of position Z of the circulation counter U3 the sampling of the tens digit, at the same time, the output is via the OR circuit M7 and the flip-flop S3 of the sequence information prepared when scanning the tens digit following space sign by switching back the flip-flop S3 to the basic position is effected. All switching processes not explained further are essentially the same those already explained in the description for the forward scan.

The circuit arrangement is not based on the illustrated embodiment and a certain electronic circuit technology. Since the number and the nature of the links between the individual logic circuits depends heavily on the structure of the track network Depending on the drainage system, many different embodiments are possible. at symmetrical structure of the track system results in a simpler circuit arrangement with less expenditure on logic circuits. Another major simplification the circuit arrangement is also possible because for some systems no Weighing indicator is provided so that all circuit parts provided for its evaluation can be omitted.

A logic circuit is an advantageous addition to the circuit arrangement for recognizing and evaluating a special telex character, e.g. B. the sign for switching between letters and digits with five code holes. This sign will used if the punched tape is wrongly "written on" for any reason and this information should not be evaluated. To this end, will the wrong information is simply overwritten with this symbol.
