Discriminatory weighing device

The invention relates to a discriminatory vehicle counter, So an electronic device that counts the position axes and thus the car, and z% »rare regardless of the type or the Type of stomach, on the speed and direction of travel.

Ü3 is already such an electromechanical vag counter, especially for jiangier railway stations. There are electromagnetic signal transmitter arranged in a certain Abstaad, so in particular rail contacts that of the The running surfaces of the wheels running over the rails are actuated will. These devices have "but no susceptibility to discrimination, So you cannot differentiate between different wagons or you can only count axles, but not differentiate, whether it is a biaxial or multi-axis Wagen acts. 90884B / 0600

However, there is already a discriminatory v / agencounter, which is also provided with such signal transmitters, which in turn have a logic Kelais circuit steer. This means that any number of consecutive wagons with any number of axles can be counted, but with the following restrictions :

The wagon discrimination or recognition sets a symmetrical arrangement of the axles in relation to the transverse center line in advance;

the device cannot discriminate against wagons with a bogie center distance greater than 2200 mm; the device cannot discriminate against wagons that have more than 8 axles;

the device cannot count the steam locomotive because it does not have a symmetrical arrangement of the axles ;

furthermore, the device only works up to a speed of 30 km / h;

the device is relatively unreliable because of the relay circuit.

The discriminatory car counting device according to the invention eliminates the above-mentioned disadvantages by the fact that it is used to discriminate or count wagons with a rotating rack: Center distance both smaller and larger than 2600 mm three electronic signal generators are used; there are two of them on one rail at a distance of 2600 mm and the

909845/0600

ORIGINAL INSPECTED

third on the other rail at a distance of 3700 towards the more distant signal transmitter. The electrical signals, on the one hand, from the arranged at a distance of 2600 mm Signal transmitters and, on the other hand, are generated by the signal transmitter located at a distance of 3700 mm, are too deu inputs of two identical logic circuits out, at their outputs a pulse for each bogie occurs; the logic circuits can be implemented in two variants; in the first variant the state of four bistable flip-flops, each paired in series through two CDiJii-EXCLUSIVE attitudes towards each other compared. The output signals then actuate an ODÜL circuit, at the output of which the bogie signal is obtained. In the second variant, the logic circuit consists of one reversible, binary, usually to 5, i.e. Ii. on "101" totalizer in the binary system; the signals of one Signalers control the totalizer forwards and those of the other backwards; any change in preference - 101 - of the totalizer is detected by an OR circuit, whose output represents the thruster signal.

The third variant can also count vagaries with a larger axle spacing of the chassis, i.e. passenger cars, essentially as follows: A bogie signal is generated through the logical processing of the impulses generated by the sensors located at a distance of 2600 mm achieved, which is connected to an AND circuit via a bistable trigger circuit.

9098.45 / 0600

will enter into which signals are also inputted from the signal transmitters located at a distance of 3700 mm are generated; the output of the AND circuit controls a OR circuit the bistable final breakdown circuit highlighting the vagaries, d. H. a single impulse corresponds to every vague if there are two axes in the range of 2600 mm, which is achieved by detection - by means of two an OR circuit controlling AND circuits - the counting positioner 111 or 011 of the reversible totalizer can be detected. The bistable End tilt circuit is directly controlled by the bogie signal obtained through the logic processing of the pulses generated by the foot levers at a distance of 2600 mm. The logic repeats itself from 0 at Passage of each car.

In order to explain the invention in more detail, exemplary embodiments are given below described with reference to the drawing.

Fig. 1 shows schematically the different types of wagons (or locomotives).

Fig. 2 is a block diagram of a counting device according to the invention, with which biaxial vague and vague with a bogie center distance of a maximum of 2500 mm can be counted, d. H. it corresponds to every vague a single impulse.

Fig. 3 shows a second embodiment variant in the block diagram, also for counting biaxial vagaries and

«09845/0600

Wagons with a bogie center distance of no more than 2500 mm.

Fig. 4 shows a block diagram of an apparatus for counting each any car.

FIGS. 5 to 8 show various signal diagrams, specifically FIG. 5 a signal diagram originating from biaxial Dare;

6 shows a signal diagram, originating from a bogie car with a bogie center distance of 2500 mm;

7 is a signal diagram originating from a carriage with a three-axle bogie, namely a diesel locomotive (the signal from the second bogie is included highlighted);

Fig. 8 shows the signal diagram of the diesel hydraulic Locomotive LDIT-70;

Fig. 9 shows the signal diagram from a bogie car with a bogie center distance of 3000 to 3600 mm.

If there were only two-axle wagons, the wagon counting would not be Problem. All that was needed was a simple counting device with a single signal transmitter; every other signal would have one Dare mean. However, there are simple wagons with only two axles and bogie wagons, with each bogie having two, three or four axes habeii can; there are also bogie wagons, in which the two bogies have different number of axles, e.g. B. two axles at the front and three axles at the back (cf. Fig. 1).

AO

In Fig. 1, Δ _Q denotes the distance between the outer axles of two coupled cars, / S ^, Δ ^, ... ^ ₅ the distance between the inner axles of different V / agengattungeu and d _o d ^. the bogie center distance of the wagons concerned.

To identify a running or standing car, three electronic signal transmitters T ₁ , T ₃ , T ₃ are used according to the invention; two signal _{transmitters T 1} and T ₃ are arranged on the one visual vise L ₁ at a distance of 2600 mm and the third signal _{transmitter T is arranged on the other rail L 3} at a distance of 3700 mm from the more distant transmitter T ₁ (Fig. 4 ).

These signal generators emit a signal when each axis passes; they are known for themselves.

To discriminate all01 two-axle wagons and all bogie wagons (with two, three or multi-axle bogies) with a bogie center distance of at most 2500 mm, two signal transmitters T, T arranged at a distance of 2600 mm are sufficient, the signals either according to the block diagram in Fig 2 or the block diagram of FIG. All types of freight wagons can also be discriminated in this way with only two signal transmitters T ₁ and T ₂ , according to FIG. 2 or 3.

However, if the center distance is greater than 2500 ram, three signal transmitters T ₁ , T ₂ , T ₃ according to FIG. 4 are required. In this way, in particular, passenger cars can be discriminated which have two-axle bogies, in particular heavy Görlitz bogies with a center distance of 3000 mm or 3600 mm.

First variant according to Fig. 2:

The signal generators T and T ₂ have bistable flip-flops

whose outputs / cWuvJxi element (SAU-L) / which controls the following elements, namely the bistable flip-flop Q _r , 'the converter A and the V.'agen counter CV. The output of the OR element SAÜ-2 also actuates the incandescent lamp 30 via the amplifier A2, which indicates whether there is an axis in the Δ zone. Furthermore, a further ODEÄ element SAU-3 ■ - as shown - is connected to the ODüLl element SAU-2 and the flip-flop element Q_, the output of which is connected to an incandescent lamp BV _{via an amplifier A 3.} The incandescent lamp BV burns as long as there is a car in the zone Δ.

B09845 / 06ÖÖ

The function of this car counter is as follows: When a four-axle car drives through the system in the direction T - T ₂ ", the first axis ara signal transmitter T initially triggers a signal that is _{tilted by the toggle Q H.} The tilting element Q ₃ does not yet receive one Input signal, so does not yet emit a signal, the EXCLUSIV-ODEii element SE-I and this subsequently the GDER element SAU-2 therefore emit an L signal.

The flip-flop Q _n . tilts at the "LG transition" of the GDER element SAU-2.

However, before the first axis reaches the signal transmitter T ₃ , the second axis already moves into zone A - i.e. into the space between the two *. Signal transmitters T ₁ , T _{3 on} , and since the center distance is smaller than this distance Δ , the first signal transmitter T ^ is actuated first.

After the first and second axes are also de *. Have actuated signal transmitter T ₂ , this actuates the bistable flip-flops Q "and Q", which in turn control the circuits SE-I and SE-2; as a result, "0" is set at the output of the OR gate SAU-2; now the Kipp ^ lied Q _{5 is} tilted into the L position; the flip-flop Q ₅ now sends a counting pulse to "deu car counter CV" via amplifier A _4.

The third and fourth axes will operate the logic system in the same "way" as the first two axes, whereof

908845/0600

when passing through this, the flip-flop Q _n still receives an impulse,

who returns it to its original position; the car counter CV "therefore only receives a single counting pulse, it only counts once.

Because the GDEß-EXCLUSIV elements S3-1 and SE-2 have been tilted for so long stay, d. H. as long as an axis is in the Z zone, the system can also use steam locomotives discriminate whose anterior and posterior axes are not arranged symmetrically, but the aforementioned «geometrical ones Fulfill the conditions, i.e. apparently have a center distance of 2500 mm.

one
Fig. 3 shows / different discrimination logic for freight wagons. The signal generators T ₁ and T _{p are} connected to a reversible binary counter S, which in turn consists essentially of three bistable flip-flops Q ₁ , Qo, Q ₃ .

The signal _{sent by the signal transmitter T 1} brings the counter into the direct counting position, after which the transmitter T. _} - delayed by the delay element L - controls the counter 5 to count upwards. The signals received from the signal generator T ₂ , on the other hand, can only operate the counter S for backward counting, in that the diode D is reversely polarized. The counter is initially at 5 or "101" in the binary system. The bi-

.809845 / 0600

Stable flip-flops CL, Q ₀ , Q ~ control the CDEIi element SAU, which then actuates the following elements, namely flip-flop Q., amplifier A1 and the agent counter CV.

The signal generator T ₁ controls an axis counter directly via amplifier A2.

When entering a z. B. four-axis Y / agens, the first axis actuates the _{signal transmitter T 1} , which now first emits a signal for setting the reversible binary counter S to count up. The first signal causes the counter to jump from the starting position 5 (or 10l) to the number 6 (or IJO).

The flip-flop Q _{0 of} the counter (which was toggled from zero to one) actuates the OR element SAU, which _{flips the bistable flip-flop Q 4} , whereby a counting pulse is sent to the Ivagencounter CV via amplifier A _{1, i.e. a car is counted.} The impulses are generated by the first and the second group of axes of the Viagens.)

Since the second axis operates the signal transmitter T ₁ in the same way, the counter S counts the number 7 or 111 (in the binary system), with the OR gate SAU remaining tilted.

The first axis actuates the signal transmitter T ₀ after driving the distance, which means that the counter now counts backwards, ie it is reset to 6 or 110. Y / enn then

90984B / 0600

the second axis actuates the signal transmitter T ", the appears Digit 5 or binary 101 in the counter. In this situation, all three inputs of the OR gate SAU have a zero signal.

So far, the flip-flop 4 has only had a single pulse obtain.

The third and fourth axes of the ¥ agent operate the counter in the same way, "the flip-flop Q ₄ thus receives another pulse that resets it to its original position; the car counter CV received only one single counting pulse.

_{If the signal transmitter T 0 is first} actuated in the opposite direction of travel, the counter S (from the starting position) first counts back to number 4 and then to number 3, whereupon it counts forward to number 4 and then 5.

The ZuIiI.:logik is also for "wagons with a larger number of axles, because there can only ever be two axes at a distance of Δ - 2600 mmm between the signal transmitters and consequently the counter cannot be controlled via position 7 or position 3.

With the arrangement of the rail contacts and the circuit according to Fig. 4 ″ can, in addition to all freight wagons (which apparently have a smaller bogie axle spacing), also passenger wagons

ORSGIMAL INSPECTED

be counted with a larger bogie center distance. Then, as already mentioned, two signal transmitters or rail contacts T, T _{0 are again} at a distance on one rail
of approx. Δ = 2600 mm provided; a third rail contact T 1 is arranged at a distance DL = 3700 mm from the first rail contact T. The signal generators T ₁ , T ₂ control a counting circuit essentially as shown in FIG. 3, and the signal generators T. and T_ control a further counting circuit combined therewith essentially according to FIG. 3. Two counting circuits are logically linked to one another.

Both counting circuits are each connected to an input of an AND element SI-I, which controls a flip-flop JICl via a QD & i element SAU-I, which controls one for each car
Emits counting pulse. The logical processing of the pulses from the signal transmitters T ₁ and T ₀ results in a bogie signal which reaches the AND circuit SI-I via the bistable trigger circuit Q _5. Arrives at the AND gate SPl
also the bogie signal originating from the signal _{transmitters T 1} , T _3.

The flip-flops Q ₁ , Q ₂ * G ₃ ^{of the} signal generators T ₁ , T ₂ associated counter SI are - as shown in Fig. 4 - connected to two AND-i elements SI-3 and SI-4, their outputs

are connected to an OR gate SAU 2, which is connected to a

ORIGINAL IHSPECTED

If there are two axes between the signal transmitters T ₁ , T ₂ , the associated counter Si is set to 111 or 011, so a signal appears at the AND element SI-3 or SI-4 and thus at the output of the OR element SAU-2.

The bogie signal is also actuated via AND gate SI-2 and OR gate SAU 2 the flip-flop JK-I. If two axes are present in the "Δ" zone, the OR gate is blocked SAU-2 operated flip-flop F, the AND gate SI-I and enables the AND gate SI-2.

As can be seen, the logic repeats itself when passing through each car.

The device according to the invention for counting and discriminating the car has the following advantages: In execution according to Fig. 2 or 3 freight wagons of all types are counted;

In the embodiment according to FIG. 4, all railway cars are counted at all, including passenger cars with a bogie spacing of 3000 mm or 3600 mm. All variants of the system can discriminate or count steam locomotives (at Steam locomotives have the difficulty that the locomotive has a different number of axles at the front than at the rear)

The counting devices are independent of the direction of travel and speed.

90.9845 / 0600

The counting devices have a high level of reliability.

It should be mentioned that the distances between the rail contacts correspond to the usual center distances or bogie center distances correspond to the existing wagons, so if wagons with different bogie center distances were used, see above there would also be such distances between the rail contacts change accordingly.
