Definitions
- the invention relates to a method for detecting short circuits between Cores of different switch drives or wires of it connected multi-wire cables, in particular four-wire cables.
- multi-wire cables can be routed together in one cable become. This means that the multi-wire lines are adjacent to each other are arranged. If it comes to a damage of the cable, it can Short circuits between wires of different multi-wire cables come. Such short circuits are referred to as wire connections. In many Applications can cause such wire connections to dangerous situations to lead.
- Multi-wire cables especially four-wire cables, become common used to provide a point control with a point machine connect.
- wire connections in cables between point controllers and point machines or directly between cores of turnout drives occur, it can be faulty Turning points come, which can result in train accidents. Therefore It must be ensured that it does not lead to faulty points comes due to wire connections.
- the object of the invention is to provide a method for wire termination monitoring create a fast and reliable way of detecting wire connections can.
- a switch can occupy two end positions. When the switch has taken a first end position, have a first and second EndlagenAuth in a points drive a first position and at a second end position take a second position. For example, can be provided that in a first end position the first wire of a Point machine is connected to the second wire of the points drive and the third vein is connected to the fourth vein. In a second end position can be provided that due to the corresponding position of Endlagenessore the first wire is connected to the fourth wire and the second wire is connected to the third wire. In a different kind of Connection, for example, when the first wire connected to the third wire This indicates that a switch tongue is not its final position has taken. This indicates that the switch has opened. This Condition is to determine, in order to avoid train accidents.
- a first at each turnout drive Monitoring signal i. a first pulse train with a first pulse duration in a first wire of the points drive or a connected thereto Multi-wire line, in particular four-wire line, fed.

- the type of Short circuit and the phasing of the different Weichenantriebe fed first pulse train with the first pulse duration can due to a change in the signal generated by the first device is output, it is determined whether a short circuit has occurred. If however, for example, a short circuit between the first wire of a first Switch drive and the first wire of a second points drive occurs, and the first pulse trains having the first pulse duration the same phase it may happen that a short circuit is not detected. Therefore, one of the turnout drives becomes a climb test mode performed, and the output signals to the other Point drives monitored.
- a second pulse train becomes one with another Pulse duration as that of the first pulse train fed. Becomes an output signal, which are associated with a second pulse train having a second pulse duration can be found on another turnout drive, this indicates one Short circuit.
- the Auffahrtestmodus successively in all turnout drives in particular one Signal box, is performed. This measure ensures that within a larger array of turnout drives, all shorts be determined.
- the first pulse sequence in the different Point machines in end position monitoring mode unsynchronized fed.
- This measure can already during the Endlagenüberwachungsmodus a occurring short circuit are detected if, for example, in a point drive through the first device Signal is output, if actually a pulse break is expected. Consequently short circuits can be detected very quickly.
- the Pulse duration of the first pulse sequence is shorter, in particular 50ms, than that of second pulse sequence, in particular 200 ms.
- the duration of the pulses of the pulse trains depends on the sensitivity of an evaluation device.
- the pulse durations of Both pulse sequences should differ so far that in the case of received signals a clear difference can be detected and the detected pulse durations unambiguously the pulse sequences of the first or second duration can be assigned.
- the break is identical between the pulses in the first and second pulse train. In particular, a break of about 1000ms may be provided.
- the evaluation of whether a short circuit exists can be simplified if Classes of shorts are defined and based on the class division the short circuit is located.
- a first class of short circuits can be provided that a short circuit between a first wire of a first and a first wire of a second switch drive is present, a short circuit between a first wire of a first point machine and a second one Core of a second points drive or a short circuit between a second wire of a first point machine drive and a second wire of a second point drive is present. This kind of shorts always has the same effect on the output signals.
- a Short circuit between a first wire of a first point machine drive and a third wire of a second turnout drive, between a first wire a first point drive and a fourth line of a second Point machine, between a second wire of a first point machine drive and a third wire of a second turnout drive or a second wire a first point drive and a fourth line of a second Point drive is present.
- a third class is that a short circuit between a third Core of a first and a third core of a second points drive exists, a short circuit between a third wire of a first and a fourth wire of a second point machine or a fourth wire of a first and a fourth core of a second points drive is present.
- a second and third wire of each turnout drive are connected by a first device, wherein in the ascent test mode, a state change signal to the first Facility is given and, as a result, the second and third vein be shorted.
- the first device no signal is output when a pulse train is fed into the first wire becomes. Rather, a second device is monitored, which is connected to the fourth wire connected.
- Simultaneously with the short circuit of the second and third Vein is the pulse sequence with the second pulse duration in the first vein of Point drive, for which the ascent test mode is performed, fed.
- a End position monitoring test mode is performed. This can be checked whether the end position detection works reliably.
- the End position monitoring test mode is no pulse sequence in the first wire fed. Accordingly, no pulse sequence by the first or second device can be detected. If this is the case, then it is again a short circuit to another point machine.
- a device for detecting Short circuits between wires of different point machines or so connected multi-wire cables comprising a plurality of point machines with each a first device connected between a second and third wire is arranged, and a second device attached to a fourth wire is arranged, wherein at least one control device for feeding a first pulse sequence in a first wire of the turnout drives during a Endlagenüberwachungsmodus and a second pulse train in a first Wire provided by a points drive during a Auffahrtestmodus and one related to the first and second devices Evaluation is provided. It can be provided that the first and second device have different sensitivities.
- control device it may be provided a single control device, all Point machines with a first or second pulse train, in particular first or second pulse duration, - depending on the operating mode - controls, or it can Several control devices can be provided, in particular, for each Switch drive a control device may be provided.
- the control device can be directly or by means of a pulse generator by the control device is driven, a first or second pulse train in a vein of a Feed point machine.
- a central Evaluation provided, so that with the one evaluation for the entire turnout system can be determined, whether in one place a wire has occurred.
- the Evaluation device Location means for locating a short circuit having. Localization can be simplified if the shorts in Classes are divided. If unexpected by the evaluation Signals can be received, so along with information the Control device, which say in which point drive in which Operating mode has been worked out, between which Turnout drives a short circuit has occurred.
- a points drive 10 which has an interface 11 having. At the interface 11, the wires 1 to 4 are connected.
- the Core 1 is with a first motor winding 12, the wire 3 with a second Motor winding 13 and the wire 4 connected to a third motor winding 14.
- an end position detection device 15th arranged between the wires 1,2,3 arranged.
- limit switches 16, 17 are provided, depending on Position of the tongue of a switch their position. In the illustrated Position of the limit switches 16, 17 is the switch, by the Point machine 10 is driven in an end position. This means that the Cores 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 connects the End position contact 17, the wires 1 and 4 and the end position contact 16, the wires. 2 and 3.
- the point machine 10 is shown, with the associated Soft is ascended. This means that at least one tongue of the Do not be in an end position. In this situation, the wire is 1 with the wire 3 via the limit switches 16, 17 electrically connected. This condition must be recognized and avoided.
- the points drive 10 is shown, wherein the interface 11th a first and second means 20, 21 are connected.
- the Means 20, 21 is essentially a current measured, the Devices 20, 21 have different sensitivities.
- the point machine 10 is shown in a state when the switch has taken a final position.
- the vein 1 is a first Pulse train 22 fed with a first pulse duration.
- the wires 1, 2 through the end position contact 17 are electrically connected to each other, the first pulse sequence 22 detected by the first device 20 and the output 23rd output as pulse sequence 24.
- This pulse train 24 becomes one Evaluation unit supplied, which assign the pulse train 24 of the pulse train 22 can.
- the first device 20 Since the first device 20 is high impedance, only a very small flows Current 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 is not responds and thus no pulse sequence is output. This means that neither at the output 25 nor at the output 26, a signal is output. There at the output 23 as expected, the signal 24 is output, recognizes the Evaluation that the end position contacts 16, 17 in the right Position is located.
- the point machine 10 is again shown in an end position. Now, however, the driveway test mode at this point machine 10 carried out.
- a Control means a second pulse train 28 having a second pulse duration, the especially longer than the first pulse duration, is fed. simultaneously is input to the first device 20 via the input 29 State change signal 30 given, whereby the wires 2, 3 in the Device 20 short-circuited. In this way one becomes Trained switch simulated. This is to test if the End-position detection works reliably. Because of these settings will be at the output 26 one of the pulse train 28 to be assigned pulse sequence 31st output. If no signal 31 is received in the ascension test mode, the signal is present Error in point machine 10 before. Furthermore, the signal 31, the one allowed second pulse sequence corresponds to a second pulse duration, only on Point machine 10 and are not recognized at any other point machine. If this were the case, a short circuit between the points drive 10 would and another turnout drive on which the signal 31 occurs.
- FIG. 6 there are three different ones Operating modes of a first point machine shown.
- the first Double arrow 40 is a Endlagenüberwachungsmodus ago.
- the driveability test mode is performed during the Double arrow 42, the end position monitoring test mode is performed, This is followed again by the end position monitoring mode 40.
- This in a first wire of a first point drive fed signal is with the Reference numeral 22a marked.
- the first pulse train 22 is fed with a first pulse duration. Accordingly, at the first device 20 of the first Point drive at the output 23, the signal 24a output.
- the ramp test mode 41 am first point drive is initiated by the state change signal 30, which on the input 29 of the first device 20 of the first Point drive is given (signal 29a).
- the Pulse train 31 which corresponds to the pulse train with second pulse duration 28 (signal 26a), output at the output 26 of the first points drive.
- the second device 21 of the second point drive is no signal (Signal 26b) or no signal change output. This means that no Short circuit occurred.
- signal 45 causes a short circuit at the location of the first one dotted line indicated, wherein it is in Fig. 7 to a Short circuit of the first class. Since the first wires (signals 22a, 22b) in the example fed synchronously with a pulse train 22 of a first pulse duration If the short circuit is not detected immediately, because in signal 24b a Superposition of the signals takes place. would the pulse sequences 22 to the first If the leads were fed out of phase, a short circuit would be detected the signal 24b would have additional pulses. This could be a Short circuit detected earlier. In Fig. 7, however, is the worst to be assumed case.
- the pulse train 31 appears not only in the signal 26a but also in the signal 24b at the output 23 of the second points drive. These broad pulses are likely do not occur there. Therefore, the evaluation can not later than this Determine that a first class short circuit has occurred.
- Fig. 8 the behavior of the point machines in a short circuit of second class presented.
- the short-circuit signal is again at 45 designated. Due to the short circuit, the level change in signal 24b drops away as soon as the short circuit 45 has occurred.
- the Signal 26b erroneously signaled a startup, due to the pulse train 46 is detected.
- a signal 31 with wide pulses in the signal 26b of the second point drive to detect.
- the evaluation device can at a short circuit of the second class so in two ways the Detect short circuit.
- FIG. 9 shows the situation for a class three short circuit. Due to the short circuit (signal 45) occur during the ramp test mode 41 in the first turnout drive at the output 26 unexpectedly wide pulses the pulse train 31 (signal 26b). These pulses are likely at the second Turnout drive not occur, since the second point machine is not in the Ascent test mode is located. Signals that a pulse train with a second Pulse duration, but may occur only when the Point machine is in the ascent test mode. Thus can also one Short circuit of the class three are unequivocally recognized. Because the The evaluation device knows in which point drive the ascent test mode is carried out and in which point drive an unexpected signal occurs, it can be determined between which turnout drives or between which veins of which turnout drives Short circuit occurred.
