For railway switch control device and railway switch drive unit are linked together, usually use the lead of multiply circuit, particularly four strand line conductors.Usually a plurality of railway switch control device are installed on the part stent, so the lead of the multiply circuit in common cable can be directed in the railway switch.If in the cable between railway switch control device and railway switch drive unit, directly in the heart yearn of railway switch drive unit, short circuits between conductors appears perhaps, may cause the railway switch positional fault, its possibility of result causes railroad accident.Therefore must guarantee, because the short circuit between the heart yearn can not cause the railway switch positional fault.
Summary of the invention
The objective of the invention is to set up the method for monitoring short circuits between conductors, in this way can be fast and discern short circuits between conductors reliably.
The present invention realizes this purpose by method mentioned above, use the endpoint monitoring pattern with first pulse train therein, the pulse train feed-in railway switch drive unit that particularly will have first pulse width first heart yearn separately or each first heart yearn of the lead of the multiply circuit that is attached thereto separately, and for railway switch drive unit execution collision detection pattern, wherein with second pulse train, first heart yearn that particularly will have the lead of first heart yearn of pulse train feed-in railway switch drive unit of second pulse width or the multiply circuit that is attached thereto, and the pulse train of exporting on one or more other heart yearns with each comfortable railway switch drive unit is obtained and is handled.Preferably, first and second pulse trains are different.Particularly they have different pulse widths.
A railway switch can have two final positions.When if railway switch is in first final position, the contact, first and second final positions on the railway switch drive unit has first state, and when being in second final position, they have second state.For example can be provided with, on first final position, first heart yearn of railway switch drive unit is connected with second heart yearn of railway switch, and the 3rd heart yearn is to be connected with the 4th heart yearn.Can be provided with on second final position, because the corresponding states of contact, final position, first heart yearn is connected with the 3rd heart yearn, and second heart yearn is connected with the 3rd heart yearn.When other connected modes,, this means that point tongue is not in its final position if for example first heart yearn is connected with the 3rd heart yearn.This has illustrated that railway switch collides.This state is suitable for determining to avoid railroad accident.For this purpose, carry out the final position monitoring with the final position monitoring mode, that is to say and will have the first pulse train feed-in railway switch of first pulse width, the lead of the multiply circuit that perhaps is attached thereto, particularly first heart yearn of four strand line conductors.
If railway switch is in the final position,, can give first pulse train with this signal allocation with first pulse width so measure and export corresponding signal by first device that is arranged between railway switch second and the 3rd heart yearn.According to the phase place of first pulse train of first pulse width of the different railway switch drive units of mode of short circuit, can determine whether to occur short circuit changing on the ground foundation by the first device output signal with feed-in.Yet for example, if between first heart yearn of first heart yearn of the first railway switch drive unit and the second railway switch drive unit, short circuit occurs, and the same phase time of first pulse train with first pulse width, might occur discerning short circuit.Therefore one of railway switch drive unit is carried out the collision detection pattern, and the output signal on other railway switch drive units is monitored.
During the collision detection pattern, will have the second pulse train feed-in of the pulse width different with first pulse train.If on other railway switch drive unit, when having determined to distribute to the output signal of second pulse train, then mean a short circuit with second pulse width.
In the preferable methods modification,, particularly sequentially carry out the collision detection pattern at Central Load Dispatching Office at all railway switch drive units.Guaranteed by this measure, in bigger railway switch drive unit, determined all short circuits.
Preferably, use the final position monitoring mode, the railway switch drive unit that first asynchronous ground of the pulse train feed-in is different.By this measure, during the monitoring mode of final position, can detect the short circuit of appearance, if for example in the railway switch drive unit by signal of the first device output, if when originally expecting a pulse width.So can determine short circuit especially soon.
Can consider that in the preferable methods modification pulse width of first pulse train is shorter than the pulse width of second pulse train, the pulse width of first pulse train 50ms particularly wherein, the pulse width of second pulse train is 200ms particularly.The pulse width of pulse train is relevant with the sensitivity of apparatus for evaluating.The difference of the pulse width of two pulse trains should be done like this, can determine tangible difference and can distribute to the pulse train of first or second width significantly when received signal when measuring pulse width.Can be provided with like this, the width between the pulse of first and second pulse trains can equate.Can consider that particularly width is approximately 1000ms.
If definition short-circuit-type and divide when locating by means of the type of short circuit can judge whether that the assessment that short circuit occurs simplifies.Following several situation can be used as first kind short circuit and considers, between first heart yearn of first heart yearn of the first railway switch drive unit and the second railway switch drive unit, short circuit occurs, occurring short circuit between second heart yearn of first heart yearn of the first railway switch drive unit and the second railway switch drive unit and between second heart yearn of second heart yearn of the first railway switch drive unit and the second railway switch drive unit, short circuit occurring.This short circuit mode has same effect all the time to output signal.
Following situation can be used as the second class short circuit, short circuit appears between the 3rd heart yearn of first heart yearn of the first railway switch drive unit and the second railway switch drive unit, between the 4th heart yearn of first heart yearn of the first railway switch drive unit and the second railway switch drive unit, short circuit occurs, between the 4th heart yearn of second heart yearn that occurs the short circuit or the first railway switch drive unit between the 3rd heart yearn of second heart yearn of the first railway switch drive unit and the second railway switch drive unit and the second railway switch drive unit, short circuit occurs.
Following situation can be used as the 3rd class short circuit, between the 3rd heart yearn of the 3rd heart yearn of the first railway switch drive unit and the second railway switch drive unit, short circuit occurs, between the 4th heart yearn of the 4th heart yearn that occurs the short circuit or the first railway switch drive unit between the 4th heart yearn of the 3rd heart yearn of the first railway switch drive unit and the second railway switch drive unit and the second railway switch drive unit, short circuit occurs.
In the preferable methods modification, considered, the second and the 3rd heart yearn with each railway switch drive unit links together by first device, wherein when the collision detection pattern, therefore condition change signal exported to first device and with the second and the 3rd heart yearn short circuit.Simulated the situation that drives railway switch by this measure.If with pulse train feed-in first heart yearn, in this case, there is not signal output by first device.Opposite monitoring is connected the device of second on the 4th heart yearn.Along with the short circuit of the second and the 3rd heart yearn, will have the pulse train of second pulse width simultaneously, first heart yearn of the railway switch drive unit of collision detection pattern is carried out in feed-in.What should monitor is, whether distributes to this pulse train of second pulse train with second pulse width, and perhaps whether pulse train depends on second device.If this is the case, this is a sign, and the railway switch drive unit is worked reliably and can be identified the railway switch of driving.Because only on a railway switch drive unit, carry out the collision detection pattern separately, from appearance corresponding to the signal of second pulse train with second pulse width, can in other railway switch drive unit, determine, between these two railway switch drive units or between the heart yearn of railway switch drive unit, short circuit occurs.

On Fig. 3, represent railway switch drive unit 10, wherein on interface 11, connected first and second devices 20,21. Use device 20,21 to measure electric current in principle, this moment, device 20,21 had different sensitivity.Represented that on Fig. 3 railway switch is in the railway switch drive unit 10 of final position state.First pulse train, the 22 feed-in heart yearns 1 that will have first pulse width.Because by contact, final position 17, heart yearn 1,2nd, conduction connects mutually, by first device 20 discerned first pulse train 22 and in outlet 23 as pulse train 24 outputs.Pulse train 24 is inputed to the apparatus for evaluating that pulse train 24 can be distributed to pulse train 22.Because first device 20 is high ohm, have only very little electric current to flow through heart yearn 3, contact, final position 16 and heart yearn 4 arrive second device 21.Electric current is so low, does not need second device 21 and therefore output pulse sequence not.This means, promptly do not exporting 26 output signals again in outlet 25.Because as the output signal of being expected 24 in outlet 23, apparatus for evaluating has been discerned contact, final position 16,17 and has been in the tram.
Represented that on Fig. 4 railway switch is at the railway switch drive unit 10 of activation point.This means that 16,17 two of contacts, final position all are positioned at lower position.This means that also first device 20 overlaps.Therefore enough receive the signal of feed-in heart yearn 1 doughtily by second device 21, so in the pulse train 27 of outlet 26 outputs corresponding to pulse train 22.This pulse train is continued to be sent to apparatus for evaluating.There is not signal output in outlet 23.Because present output signal 27 though carry out the final position monitoring mode, can be discerned railway switch with method in this way and not be in the final position, but be in driving condition.
Represented that on Fig. 5 the railway switch drive unit is in the final position again.Yet on this railway switch drive unit 10, carry out the collision detection pattern now.This means to have second pulse train, 28 feed-ins, first heart yearn 1 of second pulse width longer by control device than first pulse width.Through inlet 29 condition change signal 30 inputed to device 20 simultaneously, thus in device 20 with heart yearn 2,3 short circuits.Simulated the railway switch that drives with method in this way.Whether use it for the detection of test final position works reliably.On the basis of this position, will distribute to pulse train 31 outputs of pulse train 28 in outlet 26.If when the collision detection pattern, do not have received signal 31, on the railway switch drive unit, fault occurred.In addition, corresponding to second pulse train, be merely able to discerning on the railway switch drive unit 10 and can not discern on the railway switch drive unit at other with second pulse width.If this is the case, can be at railway switch drive unit 10, and occurring short circuit occurring between other railway switch drive units of signal 31.
Three different methods of operation on the figure that Fig. 6 represents, having represented the first railway switch drive unit.The final position monitoring mode appears during first double-head arrow 40.During double-head arrow 41, carry out the collision detection pattern, and during double-head arrow 42, carry out final position control and measuring pattern, connect the final position monitoring mode then again.Feed-in indicates for the signal of the first railway switch drive unit, first heart yearn with Reference numeral 22a.During final position monitoring mode 40, first pulse train 22 is with the first pulse width feed-in.Accordingly, on first device 20 of the first railway switch drive unit, signal 24a exported in outlet 23.If accidental feed-in is to the second railway switch drive unit, first heart yearn in the same manner with first pulse width, 22 phase places with pulse train, this represents with Reference numeral 22b.Correspondingly signal 24b is exported in first device, 20 the outlet 23 of the second railway switch drive unit.Can be by apparatus for evaluating with signal 24a, 24b distributes to first heart yearn of feed-in, and uses 22a, the pulse train 22 of 22b sign.After final position monitoring mode 40, on the first railway switch drive unit, carry out collision detection pattern 41.This means that the first railway switch drive unit (signal 22a) is given in pulse train 28 feed-ins that will have second pulse width.Give the second railway switch drive unit (signal 22b) with pulse train 22 feed-ins then.Collision detection pattern 41 on the first railway switch drive unit is by condition change signal 30 guiding, and condition change signal is (the signal 29a) in inlet 29 inputs of the device 20 of the first railway switch drive unit.To export in the outlet 26 of the first railway switch drive unit corresponding to the pulse train 31 of the pulse train with second pulse width 28 (signal 26a) now then.From second device, 21 the outlet 26 of the second railway switch drive unit not output signal (signal 26b) or not output signal change.This means, short circuit do not occur.
On Fig. 7, represented short circuit, on Fig. 7, related to the first kind short circuit this moment in the first dotted line place by signal 45.(signal 22a is with the pulse train 22 synchronous feed-ins of first pulse width 22b), can not discern short circuit immediately, because on signal 24b signal overlap is arranged because first heart yearn in example.If on first heart yearn with the feed-in of pulse train 22 phase shift ground, thereby might discern short circuit, signal 24b might extra-pulse.Thereby might be than earlier short circuit being discerned.Yet on Fig. 7, represented the worst imaginary situation.If because condition change signal 30 installs overlap joint with first of the first railway switch drive unit, pulse train 23 not only appears among the signal 26a, and appear among the signal 24b of second railway switch drive unit outlet 23.Do not allow to occur this wide pulse.Therefore apparatus for evaluating is determined on a time the latest, first kind short circuit occurred.
The situation of railway switch drive unit when having represented on Fig. 8 when the second class short circuit.Short-circuit signal is still represented with 45.In case short circuit 45 occurs, the level on short-circuit signal 24b changes and stops.In addition, can discern by signal 26b by pulse train 46 and circulated a notice of collision mistakenly.In addition, should the signal 31 that have broad pulse among the second railway switch drive unit signal 26b be detected.When the second class short circuit, apparatus for evaluating can detect short circuit on double meaning.
The situation of on Fig. 9, having represented the 3rd class short circuit.On the basis of short circuit (signal 45), during collision detection pattern 41, export the broad pulse 31 (signal 26b) that 26 appearance are not expected at the first railway switch drive unit.Do not allow on the second railway switch drive unit, these pulses to occur, because the second railway switch drive unit is not in the collision detection pattern.Yet only allow the signal of appearance, if the railway switch drive unit is in the collision detection pattern corresponding to pulse train with second pulse width.Therefore undoubtedly, also can discern the 3rd class short circuit.Because apparatus for evaluating is known, which which, can determine at the signal of carrying out the collision detection pattern on the railway switch drive unit and on railway switch drive unit, occurring not expecting, between which railway switch drive unit, perhaps between the heart yearn of which railway switch drive unit short circuit appears.
