Definitions

  • the invention relates to a method for detecting short circuits between wires of different point drives or wires of multi-wire lines connected thereto, in particular four-wire lines.
  • multi-wire cables can be routed together in one cable. This means that the multi-wire lines are arranged adjacent to each other. If the cable is damaged, short circuits can occur between the wires of different multi-wire cables. Such short circuits are referred to as Adem say. In many Applications, such Adem Why can lead to dangerous situations.
  • Multi-wire lines are often used to connect a point controller to a point machine. Often several points controls are arranged in a rack, so that the multi-wire cables can be performed in a common cable to the switch. If wire connections occur in cables between point controllers and point machines or directly between cores of point machines, it can lead to incorrect placement of points, which can result in train accidents. Therefore, it must be ensured that it does not lead to incorrect turnouts due to wire connections.
  • the object of the invention is to provide a method for wire connection monitoring, with the wire connections can be detected quickly and reliably.
  • a method of the type mentioned in which in a Endlagenüberwachungsmodus in each case a first wire of the turnout drives or connected thereto multi-wire lines, a first pulse train, in particular with a first pulse duration, is fed and carried out a Auffahrtestmodus for a points drive is, wherein in the first wire of the points drive or the connected multi-wire line a second pulse sequence, in particular with a second pulse duration, is fed in and the pulse sequences output in each case at one or more other wires of the point machines are detected and evaluated.
  • the first and second pulse sequences are preferably different, in particular they have different pulse durations.
  • a switch can occupy two end positions.
  • a first and second end position contact have a first position in a points drive and a second position at a second end position.
  • the first wire of a points drive is connected to the second wire of the points drive and the third wire is connected to the fourth wire.
  • a second end position can be provided that due to the corresponding position of the Endlagenessore the first wire is connected to the fourth wire and the second wire is connected to the third wire.
  • a limit position monitoring in a Endlagenüberwachungsmodus is performed.
  • a first monitoring signal i. a first pulse train having a first pulse duration in a first wire of the points drive or a multi-wire line connected thereto, in particular four-wire line, fed.
  • a corresponding signal is detected and output via a first device, which can be arranged between the second and third wire of the switch drive, which signal can be assigned to a first pulse sequence with a first pulse duration.
  • a first device which can be arranged between the second and third wire of the switch drive, which signal can be assigned to a first pulse sequence with a first pulse duration.
  • a short circuit occurs between the first wire of a first point machine drive and the first wire of a second point machine, and the first pulse sequences with the first pulse duration have the same phase, a short circuit may not be detected. Therefore, a ramp test mode is performed for one of the turnout drives, and the output signals at the other turnout drives are monitored.
  • a second pulse train with a different pulse duration than that of the first pulse train is fed in. If an output signal that can be assigned to a second pulse train with a second pulse duration is detected at another point drive, this indicates a short circuit.
  • the ascent test mode is carried out successively in all turnout drives, in particular an interlocking. This measure ensures that all short circuits are detected within a larger arrangement of point machines.
  • the first pulse train is preferably fed unsynchronized into the different point machines in the end position monitoring mode.
  • an occurring short circuit can already be detected during the end position monitoring mode if, for example, a signal is output by the first device in a turnout drive when a pulse pause is actually expected.
  • short circuits can be detected very quickly.
  • the pulse duration of the first pulse sequence is shorter, in particular 50 ms, than that of the second pulse sequence, in particular 200 ms.
  • the duration of the pulses of the pulse sequences depends on the sensitivity of an evaluation device.
  • the pulse durations of the two pulse sequences should differ so far that a clear difference can be detected in the received signals and the detected pulse durations can be unambiguously assigned to the pulse sequences of the first or second duration.
  • the pause between the pulses in the first and second pulse train is identical. In particular, a break of about 1000ms may be provided.
  • the evaluation of whether a short circuit exists can be simplified if classes of short circuits are defined and the short circuit is localized on the basis of the class classification.
  • a first class of short circuits can be provided that there is a short circuit between a first wire of a first and a first wire of a second points drive, a short circuit between a first wire of a first points drive and a second wire of a second points drive or a short circuit between a second Core of a first point machine drive and a second wire of a second points drive is present.
  • This type of short circuit always has the same effect on the output signals.
  • a short circuit between a first wire of a first points drive and a third wire of a second points drive, between a first wire of a first points drive and a fourth wire of a second points drive, between a second wire of a first Weichenahtriebs and a third wire of a second points drive or a second wire of a first points drive and a fourth wire of a second points drive is present.
  • a third class is that there is a short circuit between a third wire of a first and a third wire of a second turnout drive, a short circuit between a third wire of a first and a fourth wire of a second point drive or a fourth wire of a first and a fourth wire of a second point drive is present.
  • a second and third wire of each points drive are connected by a first device, wherein in the ascent test mode a state change signal is given to the first device and consequently the second and third wires are short-circuited.
  • This measure simulates the case of a driven switch. In this case, no signal is output by the first device when a pulse train is fed to the first wire. Rather, a second device is monitored, which is connected to the fourth wire. Simultaneously with the short circuit of the second and third wires, the pulse train of the second pulse duration is fed to the first wire of the point machine for which the ascent test mode is performed.
  • this pulse train or a pulse train that can be assigned to the second pulse train with the second pulse duration, arrives at the second device. If this is the case, it is also a sign that the turnout drive is working reliably and an upset turnout is detected. Since the Auffahrtestmodus is carried out in each case only at a points drive, it can be determined from the occurrence of a signal corresponding to a second pulse train with a second pulse duration at another point drive that there is a short circuit between these two point drives or between wires of these points drives.
  • a limit position monitoring test mode is performed. This makes it possible to check whether the end position detection functions reliably.
  • no pulse sequence is fed into the first wire. Accordingly, no pulse sequence may be detected by the first or second device. If this is still the case, there is again a short circuit to another point machine.
  • a device for detecting short circuits between wires of different point drives or associated multi-wire lines comprising a plurality of point drives each having a first device which is arranged between a second and third wire, and a second Means arranged on a fourth wire, at least one control device being provided for feeding a first pulse train into a first wire of the points drive during a end position monitoring mode and a second pulse train into a first wire from a point drive during an ascent test mode, and one with the first one and second device associated evaluation is provided. It can be provided that the first and second device have different sensitivities.
  • control device can feed directly or by means of a pulse generator, which is controlled by the control device, a first or second pulse train into a wire of a points drive.
  • a central evaluation device is provided, so that it can be determined with the one evaluation device for the entire switching system whether an Adem gleich has occurred at one point.
  • the evaluation device has location means for locating a short circuit. Localization can be simplified if the shorts are divided into classes. If unexpected signals are received by the evaluation device, it can be determined together with information of the control device which indicates which point drive was used in which operating mode, between which point drives a short circuit has occurred.
  • a point machine 10 which has an interface 11. At the interface 11, the wires 1 to 4 are connected. The wire 1 is connected to a first motor winding 12, the wire 3 to a second motor winding 13 and the wire 4 to a third motor winding 14. Between the wires 1,2,3 an end position detection device 15 is arranged. Furthermore, end position contacts 16, 17 are provided which change their position depending on the position of the tongue of a switch. In the illustrated position of the end position contacts 16, 17, the switch, which is controlled by the point machine 10, in an end position. This means that the wires 1, 2 are connected via the end position contact 17 and the wires 3,4 are connected via the end position contact 16. Between the wires 1, 2 and 3, 4 there is no electrical connection. In a second end position of the end position contact 17 connects the wires 1 and 4 and the end position contact 16, the wires 2 and 3.
  • Fig. 2 the points drive 10 is shown, wherein the associated switch is ascended. This means that at least one tongue of the switch is not in an end position. In this situation, the wire 1 with the wire 3 via the limit switches 16, 17 is electrically connected. This condition must be recognized and avoided.
  • the points drive 10 is shown, wherein the interface 11, a first and second means 20, 21 are connected. A current is essentially measured in the devices 20, 21, the devices 20, 21 having different sensitivities.
  • the points drive 10 is shown in a state when the switch has taken a final position.
  • a first pulse train 22 is fed with a first pulse duration. Since the cores 1, 2 are electrically conductively connected to one another by the end position contact 17, the first pulse sequence 22 is detected by the first device 20 and output at the output 23 as a pulse sequence 24. This pulse sequence 24 is supplied to an evaluation device which can assign the pulse train 24 to the pulse train 22.
  • the evaluation device Since the first device 20 is high-impedance, only a very small current flows through the wire 3, the limit contact 16 and the wire 4 to the second device 21. This current is so low that the second device 21 does not respond and thus no pulse train output becomes. This means that neither at the output 25 nor at the output 26, a signal is output. Since, as expected, the signal 24 is output at the output 23, the evaluation device detects that the limit switches 16, 17 are in the correct position.
  • the points drive 10 is shown in an ascended position of the switch. This means that the End Wegliche 16, 17 are both in the lower position. This also means that the first device 20 is bridged. By the second device 21, therefore, the fed into the wire 1 signal is sufficiently strong received, so that at the output 26 of the pulse sequence 22 corresponding pulse train 27 is output. This pulse sequence is forwarded to the evaluation unit. At the output 23, no signal is output. Since now only the signal 27 is output, although the Endlagenüberwachungsmodus is performed, it is detected in this way that the switch is not in an end position, but is in the extended state.
  • the point machine 10 is again shown in an end position. Now, however, the driveway test mode is performed on this point machine 10.
  • a second pulse train 28 with a second pulse duration which is in particular longer than the first pulse duration, is fed.
  • a state change signal 30 is given to the first device 20 via the input 29, whereby the wires 2, 3 are short-circuited in the device 20. In this way, an upset turnout is modeled.
  • a pulse train 31 to be assigned to the pulse train 28 is output at the output 26. If no signal 31 is received in the ascent test mode, there is an error in the point machine 10.
  • the signal 31, which corresponds to a second pulse train with a second pulse duration may only be detected at the point machine 10 and at no other points drive. If this were the case, there would be a short circuit between the point machine 10 and another point machine on which the signal 31 occurs.
  • FIG. 6 three different operating modes of a first point machine drive are shown.
  • the first double arrow 40 there is a Endlagenüberwachungsmodus.
  • the driveability test mode is performed, while the double arrow 42, the Endlagenüberwachungstestmodus is performed, this is followed by the Endlagenüberwachungsmodus 40 again.
  • the signal fed into a first wire of a first turnout drive is indicated by the reference numeral 22a.
  • the first pulse train 22 is fed with a first pulse duration. Accordingly, at the first device 20 of the first points drive at the output 23, the signal 24a is output.
  • a pulse sequence with a first pulse duration 22 is fed into the first wire of a second point drive in phase, which is indicated by the reference numeral 22b.
  • the signal 24b is output at the output 23 of the first device 20 of the second point drive.
  • the signals 24a, 24b can be assigned by the evaluation device to the pulse trains 22 which have been fed into the first wires and designated 22a, 22b.
  • the ascent test mode 41 is carried out in the first point machine. This means that at the first wire of the first transfer shoot (signal 22a) the pulse train 28 is fed with a second pulse duration. In the second point drive (signal 22b), the pulse sequence 22 is also fed.
  • the driveway test mode 41 at the first point machine is initiated by the state change signal 30 which is applied to the input 29 of the first device 20 of the first point machine (signal 29a). Consequently, the pulse sequence 31, which corresponds to the pulse sequence with the second pulse duration 28 (signal 26a), is output at the output 26 of the first point machine drive. From the output 26 of the second device 21 of the second points drive no signal (signal 26b) or no signal change is output. This means that no short circuit has occurred.
  • the signal 45 indicates a short circuit at the location of the first dotted line, which in FIG. 7 is a short circuit of the first class. Since the first wires (signals 22a, 22b) are fed synchronously with a pulse sequence 22 of a first pulse duration in the example, the short circuit is not recognized immediately, since in the signal 24b a superimposition of the signals takes place. If the pulse trains 22 were fed out of phase with the first wires, a short circuit would be detected by the signal 24b having additional pulses. As a result, a short circuit could be detected earlier. In Fig. 7, however, the worst case is shown.
  • the evaluation device can determine at the latest at this time that a first-class short-circuit has occurred.
  • FIG. 8 shows the behavior of the point machines in the case of a short circuit of the second class.
  • the short-circuit signal is again denoted by 45. Due to the short circuit, the level change in the signal 24b drops as soon as the short circuit 45 has occurred.
  • a startup is erroneously signaled by the signal 26b, which is detected by the pulse train 46.
  • a signal 31 is to be detected with wide pulses in the signal 26b of the second switch drive. The evaluation device can thus detect the short circuit in a short circuit of the second class in two respects.
  • FIG. 9 shows the situation for a class three short circuit. Due to the short circuit (signal 45), unexpectedly wide pulses of the pulse sequence 31 (signal 26b) occur at the output 26 during the ascent test mode 41 in the first point machine. These pulses are unlikely to occur on the second point machine, as the second point machine does not run in the middle Ascent test mode is located. However, signals that correspond to a pulse train with a second pulse duration may only occur when the point machine is in the ascent test mode. Thus, a short circuit of class three can be detected beyond doubt. Since the evaluation device knows in which point drive the ascent test mode is performed and in which point drive an unexpected signal occurs, it can be determined between which point drives or between which wires of which point drives a short circuit has occurred.
