Additionally or in the alternative, recognition unit 520 can be configured by the phase between first and second inspection signal of detection The test section for changing to determine route 604 in difference includes electric short circuit.For example, recognition unit 520 can will be by detection unit 616A Detected first and second checks the known phase between detection phase difference and the first and second inspection signals between signal Difference is relatively.The known phase difference, which can be, checks phase difference between signal when injecting a signal into route 604 or can be with Be along it is known be not damaged and not the route segment of electric short circuit check signal between detection phase difference.Therefore, if by One or more electrical characteristics that detection unit 616A is monitored indicate first and second check signal between phase difference with it is known Phase difference is similar, so that the change in phase difference is negligible or in the threshold value of compensation variation due to caused by noise etc., then road The state of the test section of line 604, which can be, not to be damaged and without electric short circuit.If the phase difference of detection becomes from known phase difference Changing is more than specified threshold (so that it is more than specified threshold that phase difference, which changes), then the state of the test section of route 604, which can be, does not damage It badly and include electric short circuit.If the test section of route 604 is potentially damaged, one or more monitored electrical characteristics can be indicated It checks that signal is not received by detection unit 616, therefore first and second is not detected and checks the phase difference between signal.
In another alternative embodiment, vehicle 602 includes an application apparatus (such as application apparatus 606A) and one Detection unit (for example, detection unit 616A).Application apparatus 606A is arranged close to detection unit 616A.For example, application apparatus 606A and detection unit 616A can the length between two branches 618 along vehicle 602 opposite rail is located at similar position On road 614A, 614B, as shown in fig. 6, or can be close to mutually positioning on same rail 614A or 614B.Application apparatus 606A be configured to by least one check signal electrical pumping into track 614, and detection unit 616A be configured to by At least one checks that signal is injected into conduction test circuit 620 the one or more electrical characteristics for monitoring track 614.
In this embodiment, recognition unit 520(is shown in FIG. 5) it is arranged to check for monitored by detection unit 616A one A or multiple electrical characteristics determine the state of the test section of the route 604 extended between branch 618.Recognition unit 520 configures At the shape for determining test section when one or more electrical characteristics indicate that at least one checks that signal is not received by detection unit 616A State is potential impaired.When one or more electrical characteristics indicate that at least one checks that signal is received by detection unit 616A, The state of test section is both not impaired or not comprising electric short circuit.Indicate that at least one checks letter in one or more electrical characteristics Phase shift in number or at least one when checking at least one in the increasing degree of signal, the state of test section is not impaired It and really include electric short circuit.Amplitude can the state of test section be it is not impaired and do not include electric short circuit when detection or Increase in the baseline amplitude of measurement.Such as be shown in FIG. 5 in signal communications system 521() detection unit 616A and application dress Set 606A it is mobile towards the electric short circuit in route 604 when, increased amplitude can be gradually increased from baseline amplitude, and for example in signal The detection unit 616A and application apparatus 606A of communication system 521 can be gradually reduced when mobile far from electric short circuit towards baseline amplitude.

Fig. 9 to 11 is the schematic diagram of the embodiment of inspection system 900 of the vehicle 902 on route 904 when driving vehicle 902 Show.The inspection system 800 that the inspection system 900 can be the inspection system 600 being shown in FIG. 6 and/or be shown in FIG. 8. Vehicle 902 can be the vehicle 602 of Fig. 6 and/or the vehicle 802 of Fig. 8.Fig. 9 to 11 illustrates vehicle 902 in driving direction 906 The various route conditions being likely encountered when being passed through along route 904.
Vehicle 902 includes two conveyers or applying unit 908A and 908B and two receiver or detection unit 910A And 910B, it is all vehicle-mounted to be arranged on vehicle 902.Applying unit 908 and detection unit 910 are along by the branch on vehicle 902 The conductive loop 912 that the route 914 of route 904 between branch limits positions.For example, vehicle 902 may include six wheel shafts, Each wheel shaft and route 914 are attached to two vehicles in electrical contact and form branch.Optionally, conductive loop 912 can be most It is defined between the wheel shaft of the inside (for example, between third and fourth round axis) to reduce the signal by other wheel shafts and/or vehicle frame The amount of loss.Therefore, the end of the third and fourth wheel axis limit conductive loop 912, and route 914 limits being conducted back to for connecting pin The section on road 912.
Conductive loop 912 limits test loop 912(for example, test section) for detecting the failure in route 904 and inciting somebody to action It damages route 914 and short-circuit false alarm is distinguished.When vehicle 902 passes through route 904, check that signal is single from the first application for first First 908A is injected into the first line 914A of route 904, and the second inspection signal is injected from the second applying unit 908B Into the second route 914B of route 904.The first and second inspections signal can while or be injected into route 904 with alternating series In.First and second inspection signals can each have unique identifier with when signal when test loop 912 is recycled by first Check that signal and second checks signal distinguishing.First checks that the unique identifier of signal may include frequency, modulation, embedded signature And/or it is all because such, check that the unique identifier of signal is different from second.For example, the first inspection signal can have than second Check the higher frequency of signal and/or with the embedded signature different from the second inspection signal.Alternatively, check that signal can have There is different frequencies to allow that signal is distinguishable from one another.For example, can be incited somebody to action with 4.6 kilo hertzs (kHz) of frequency or another frequency First inspection signal be injected into route, and with 3.8kHz(or another frequency) frequency by second inspection signal be injected into road In line.In one embodiment, signal can have different identifiers and different frequencies.
In Fig. 9, vehicle 902 crosses the section of route 904, is complete (for example, not being damaged) and does not have electricity Short circuit.Because in the region in conduction test circuit 912, (it is between two specified branches (for example, wheel shaft) of vehicle 902 Region) it is interior that there is no electric short circuit or electrical destructions, first and second to check signals all in test loop 912 on route 904 Overall length circulation.Therefore, it when first checks that signal code is flowed around test loop 912, is transmitted by the first application apparatus 908A First check signal code by both first detection device 910A and second detection device 910B detect.Although in different positions Second inspection signal is injected into route 904 by the place of setting, but second checks that signal code checks together with signal code with first It recycles in test loop 912, and is equally detected by both detection devices 910A, 910B.It is every in detection device 910A, 910B A one or more electrical characteristics that can be configured to detect along route 904 close to corresponding detection device 910.Therefore, when route segment does not have It include every in the first and second inspection signals by the received electrical characteristics of each of detection device 910 when having short circuit and destroying A signature unique.
In Figure 10, vehicle 902 crosses the section of route 904, and it includes electric short circuits 916.The electric short circuit 916 can be route Device on 904 makes the first transmission line 914A conduct and/or inductively be coupled in the route 904 of the second transmission line 914B Condition.Electric short circuit 916 causes the electric current being injected into a route 914 to flow through short circuit 916 to another route 914, rather than Overall length along conduction test circuit 912 flows and intersects between route 914 at branch.For example, short circuit 916 can be it is useless Other external conduction devices, nonisulated signal cross or switch that sheet metal or cross-line road 914 position, due to wearing or damaging and Insulated switch or connector in nonisulated route 914 etc..Electric short circuit 916, which is crossed, along route 904 in vehicle 902 makes short circuit 916 are at least temporarily located between the branch in the region limited by test loop 912, and test loop 912 can short circuit.
When vehicle 902 crosses electric short circuit 916, electric short circuit 916 makes recycle in test loop 912 first and second to check The electric current flowing of signal is transferred to redundant mesh.For example, first checks that signal can be by 916 transfer of short circuit mainly along the first conduction Short-circuit loop 918 recycles, and the first conduction short-circuit loop 918 is along the road between the first application apparatus 908A and electric short circuit 916 The section of line 904 limits recently.Similarly, second check that signal is transferable mainly to recycle along the second conduction short-circuit loop 920, it should Second conduction short-circuit loop 920 limits recently along the section of the route 904 between electric short circuit 916 and the second application apparatus 908B. The first short-circuit loop 918 is significantly only passed through by the first inspection signal of the first application apparatus 908A transmission, and is only answered by second The second short-circuit loop 920 is significantly passed through with the second inspection signal of device 908B transmission.
Therefore, the one or more electrical characteristics for the route for being received and/or being monitored by first detection unit 910A can be indicated only First checks the presence of signal.Equally, the one or more electricity for the route for being received and/or being monitored by second detection unit 910B is special Property can only indicate the presence of the second inspection signal.As used herein, " instruction " checks that " presence " of signal means received electricity Characteristic comprises more than the pure threshold signal-to-noise ratio of unique identifier, and unique identifier instruction is more than that the corresponding inspection of electrical noise is believed Number.For example, the presence because can only indicate the second inspection signal by the received electrical characteristics of second detection unit 910B, second is checked Signal exceeds the threshold signal-to-noise ratio of received electrical characteristics but first checks signal without departing from threshold value.Because originating from device 908A First check signal code major part can pass through test loop 912 length to second detection device 908B forward position it is short Road 916(is for example, along the first short-circuit loop 918) it is transferred, first checks that signal can be significant not at second detection unit 908B It receives.Therefore, the received electrical characteristics with the unique identifier for indicating that first checks signal at second detection device 910B It can be obviously reduced when vehicle 902 passes through electric short circuit 916.
It is short that the Outside Dimensions of first and second conduction short-circuit loops 918 and 920 and/or region can pass through electricity in vehicle 902 There is inversely related when road 916.For example, first short circuit is returned when the test loop 918 in vehicle 902 overcomes and passes through short circuit 916 The size on road 918 increases and the size of the second short-circuit loop 920 reduces.Pay attention to the first and second short-circuit loops 916 only in short circuit 916 form when being located in boundary or region that tested circuit 912 covers.Therefore, received instruction checks signal just the One and second conduct short-circuit 918,920 circuit cycles electrical characteristics mean section include electric short circuit 916(for example, such as be damaged Or sufficiently complete section is opposite in the case where no electric short circuit).
In Figure 11, vehicle 902 crosses the section of the route 904 comprising electrical destruction 922.The electrical destruction 922 can damage One or two route 914A, 914B cut off the conductive path (for example, or substantially reducing it) along route 914.Damage can To be route, the uninterrupted length of route etc. destroyed.Therefore, when the section of route 904 includes electrical destroy, which is formed Open circuit, and electric current is not usually along open circuit flowing.In some destructions, induced current pass through small destruction, but the magnitude of current with The non-demolition conductive sections of route 904 will relatively greatly reduce, this can be possible.
Vehicle 902 cross it is electrical destroy 922 to destroy in the boundary that 922 are located in test loop 912 (for example, Between the specified branch for limiting the vehicle 902 at 912 end of test loop) when, test loop 912 can be destroyed, to form open circuit. Therefore, the first and second signals of injection are not also recycled along any short-circuit loop in test loop 912.Because signal code is not It is flowed along the test loop 912 destroyed, the first and second detection unit 910A and 910B, which are not checked in response to first and second, to be believed Number receive any significant electrical characteristics.Once 902 passage failure of vehicle, the first and second inspection signals sequentially injected can surveyed It tries section 912 to recycle, as being shown in FIG. 9.Notice that vehicle 902 may pass through electrically to destroy as caused by the damage to route 904 Without overstepping the limit.Some destructions can support vehicular traffic for certain time amount until damage increases beyond threshold value, such as in ability It is known in domain.
As shown in Fig. 9 to 11, shown in 10 regardless of vehicle 902 is crossed with electric short circuit 916(), electrical destroy 922(is shown in FIG. 11) route 904 section or electricity it is adjacent (being shown in FIG. 9), by detection unit 910 detect along road The electrical characteristics of line 904 can be different.Inspection system 900 can be configured to distinguish the one or more electricity of the damage section of instruction route 904 One or more electrical characteristics of non-damaging section (it is with electric short circuit 916) of characteristic and instruction route 904, it is such as further herein It discusses.
By the electric signal of the inspection system monitoring on the Vehicular system when Figure 12 is shown in Vehicular system along route running 1000.The inspection system can be the inspection system 900 being shown in FIG. 9.Vehicular system may include the vehicle travelled along route 904 Both 902(is shown in FIG. 9).Electric signal 1000 is received by first detection unit 1002 and second detection unit 1004 One or more electrical characteristics.Electric signal 1000 in response to first check signal and second check transmission of the signal into route or It injects and receives.First and second check that signal each may include unique identifier, allow inspection system that will indicate the first inspection The electrical characteristics and instruction second for looking into institute's monitoring current of signal check that the electrical characteristics of signal are distinguished, even if electric current includes two inspections Signal.
In Figure 12, electric signal 1000 is marking and drawing signal 1000 in the curve graph 1010 of the amplitude (A) of time (t) to scheme The mode of table is shown.It travels and encounters along route 904 for example, curve graph 1010 can graphically be shown in vehicle 902 With reference to Fig. 9 describe various route conditions when in response to first and second check signals monitored electrical characteristics.Curve graph 1010 Can the vehicle-mounted operator on the display apparatus on vehicle show and/or can transmit vehicle external position, such as send or repair facility. First electric signal 1012, which is represented, checks that the electricity of signal is special in response to (for example, instruction) first by first detection unit 1002 is received Property.Second electric signal 1014, which is represented, checks signal in response to (for example, instruction) second by first detection unit 1002 is received Electrical characteristics.Third electric signal 1016 is represented to be believed by received check in response to (for example, instruction) first of second detection unit 1004 Number electrical characteristics.4th electric signal 1018 is represented by second detection unit 1004 is received in response to (for example, instruction) the second inspection Look into the electrical characteristics of signal.
Between time t0 and t2, electric signal 1000 indicates two inspection signals all by two detection units 1002,1004 It receives.Therefore, signal is in the length cycles (showing in figures 9 and 10) for conducting main test loop 912.At time t1, vehicle Route segment is just crossed, is complete and does not have electric short circuit, as being shown in FIG. 9.The amplitude of electric signal 1012-1018 It can be with relative constant for baseline amplitude in each of signal 1012-1018.Baseline amplitude is for signal 1012-1018 Each of need not be identical so that electric signal 1012 can have it is different from least one of other electric signals 1014-1018 Baseline amplitude.
At time t2, vehicle crosses electric short circuit.As being shown in FIG. 12, t2 is closely followed, being indicated by first detection unit 1002 it is received first check signals electric signal 1012 amplitude increase significant gain and then towards baseline amplitude gradually Reduce.It indicates to check that the amplitude of the electric signal 1014 of signal descends below electric signal by first detection unit 1002 received second 1014 baseline amplitude.Therefore, compared with corresponding baseline level, the received electrical characteristics instruction the at first detection unit 1002 One checks the bigger conspicuousness of signal or ratio (for example, the circuit 918 limited recently due to the first electric signal in Figure 10 is followed Ring), and indicate the second smaller conspicuousness or ratio for checking signal.At time t2 at second detection unit 1004, instruction First check the electric signal 1016 of signal using with by the similar mode of the received electric signal 1016 of institute of first detection unit 1002 Decline.When test loop passes through electric short circuit, instruction second check signal electric signal 1018 amplitude from time t2 to t4 by It is cumulative to be added to baseline amplitude or more.
These electrical characteristics instruction electric short circuit from time t2 to t4 limits new circuit loop in main test loop 912 (showing in figures 9 and 10).The amplitude for checking signal close to the injection of corresponding detection unit 1002,1004 is relative to baseline amplitude Increase, and the inspection signal that (and being separated by) injects from corresponding detection unit 1002,1004 on the other side of test loop Amplitude reduces (or decline) relative to baseline amplitude.For example, the amplitude of electric signal 1012 is by by the first application apparatus 908A institute The short-circuit loop that recently limits or sub-loop 918 of the first inspection signal of injection in Figure 10 recycle and by answering close to first It is received with the first detection unit 910A of device 908A and increases a stride at once.It is mobile relative to electric short circuit in the system of inspection When, because electric short circuit is further from the first application apparatus 908A and first detection unit 910A and the size of sub-loop 918 increases, The amplitude of electric signal 1012 is gradually reduced towards baseline amplitude.Electric signal 1018 by injected by the second application apparatus 908B Two inspection signals are in the circulation of short-circuit loop or sub-loop 920 limited recently and by close to the second of the second application apparatus 908A Detection unit 910B is received and is also increased relative to baseline amplitude.When the system of inspection is mobile relative to electric short circuit, because electricity is short Road is closer to the second application apparatus 908B and second detection unit 910B and the size of sub-loop 920 reduces, electric signal 1018 Amplitude gradually increase far from baseline amplitude (until time t4).Because reaching the forward position circuit decay of corresponding detection unit Signal is less than the inspection signal in bigger circuit loop, checks that the amplitude of signal can be higher for smaller circuit loop.Electricity The positive slope of signal 1018 can be opposite with the negative slope of electric signal 1012.For example, the telecommunications monitored by the first detection device 1002 Numbers 1012 amplitude can be the inverse derivative of the amplitude of the electric signal 1018 monitored by second detection device 1004.The inverse relationship Be due to vehicle along route moving relative to fixed electrical short circuit.With reference also to Figure 10, time t3 can be represented will in electric short circuit 916 Electric signal 1012-1018 when test loop 912 is halved and short-circuit loop 918,920 is with identical size.
At time t4, the test section (for example, circuit) of vehicle surmounts electric short circuit.Between time t4 and t5, curve graph The instruction of electric signal 1,000 first and second on 1010 checks that signal is all recycled in main test loop 912 again, such as shows in Fig. 9 Out.
At time t5, vehicle crosses the electrical destruction in route.As being shown in FIG. 12, t5, electric signal are closely followed Amplitude in each of 1012-1018 reduces or declines significant stride.Electrically destroying in test section pass course is whole It (is expressed as between time t5 and t7) in a time span, all four signal 1012-1018 are in low or width of at least decaying Degree, so that instruction first and second checks that signal is not recycled in test loop due to the electrical destruction in route.Time, t6 could It represents and electrically destroys 922 position relative to checking of routing system 900, as shown in fig. 11.
In embodiment, recognition unit can be configured to determine the route passed through by vehicle using received electric signal 1000 Whether section is potentially damaged, and means that section can be damaged or at least deteriorate.For example, based between time t2-t4 and t5-t7 The waveform of the record of electric signal 1000, recognition unit the route segment passed through between time t2-t4 can be identified as it is non-damaging but It is identified as being damaged with electric short circuit and by the route segment passed through between time t5-t7.For example, receiver coil or detection The all lossing signal in vehicle damage section of route via between time t5-t7 of unit 1002,1004, this is in curve graph 1010 In be clear.However, first detection unit 1002 loses the second inspection when short circuit between time t2-t4 in intersecting routes Signal is looked into, as shown on electric signal 1014, and by the received second inspection signal of representing of second detection unit 1004 The amplitude of electric signal 1018 increases when by short circuit.Thus, it is deposited between the opposite feature for making route short circuit of destruction in route In significant difference.Optionally, the curve graph 1010 on vehicle operator viewable display and based on electric signal 1000 The waveform of record by route segment manual identified be damaged or it is non-damaging but have electric short circuit.
In embodiment, inspection system can be further used for distinguishing non-damaging route spy by received electric signal 1000 Sign.For example, broadband branch (for example, capacitor) can similarly be operated with the cross shunt of rigid line high speed, not including can be according to first The frequency identification additional phase shift for checking signal with second.Narrowband (for example, tuning) branch can be by response to tuning branch frequency Show bigger phase and amplitude difference with the relationship for the frequency for checking signal to influence electric signal 1000.
Inspection system can also will due to damage caused by circuit damage and due to intentional line characteristics (such as insulating joint and Turnout (for example, line switching)) caused by electrically destroy (for example, pseudo- destroy) and distinguish.In turnout, in a particular area, Only single pair transmission and receiving coil (for example, along single application apparatus and detection unit of the positioning of transmission line) can Injection Current (for example, checking signal).This on relative line (for example, track) is to can just pass through " police rush circuit ", wherein phase Route is only electrically connected at one end rather than at the part in circulating current circuit.
Such as about insulating joint, insulating joint is distinguished and can be caused and by addition dead band circuit with track is destroyed Main test loop in extension signal deletion complete.As be in the art it is known, railway standard is indicated generally at required Insulating joint is staggered in 32 inches to 56 inches.In addition to providing and having the pseudo- insulating joint destroyed of extension length, detection may be used also The position of the signaling apparatus (for example, battery, line relay, electronic circuit circuit etc.) of insulating joint is connected to by identifying Particular signature and enhance.It is short what is limited recently by connection equipment that the position particular signature of signaling apparatus may be in response to electric current Road circuit 918,920 recycles (being shown in FIG. 9) and receives in monitored electrical characteristics.For example, usually near insulating joint The signaling apparatus found can have specific electric signature or identifier, such as frequency, modulation, embedded signature etc., allow to examine It looks into system and identifies signaling apparatus in monitored electrical characteristics.Identify that the signaling apparatus usually found near insulating joint mentions The instruction of the damage section of the insulating joint in route rather than route is just being crossed for vehicle.
In the alternative embodiment of reference Fig. 6 description, wherein the system of inspection includes at least two detection lists being separated by Member, but include less than two application apparatus (such as zero or one), so that only one checks that signal is injected into route, by two A detection unit can be shown along the electrical characteristics that route is monitored in the curve graph similar with curve graph 1010.For example, curve graph It may include the electric signal 1012 and 1016 marked and drawed, the wherein representative of electric signal 1012 is detected by first detection unit 1002 or first Received inspection signal at detection unit 1002, and the representative of electric signal 1016 is detected by second detection unit 1004 or second Received inspection signal at detection unit 1004.Using only electric signal 1012 and 1016(rather than also use 1014 and 1018) Plotting amplitude, recognition unit can determine the state of route.Between time t0 and t2, both signals 1012 and 1016 are with baseline value It is all constant (there is zero slope).Thus, both one or more electrical characteristics instruction detection units 1002,1004 receive inspection Signal is looked into, and recognition unit determines that route segment is not damaged and does not include electric short circuit.Between time t2 and t4, the first inspection It surveys unit 1002 and detects the increasing degree (although slope is negative) of the inspection signal more than baseline, and second detection unit 1004 detect the amplitude decline for checking signal.Thus, one or more electrical characteristics instruction first detection units 1002 receive inspection It looks into signal but second detection unit 1004 does not receive, and recognition unit determines that route segment includes electric short circuit.Finally, in time t5 Between t7, both the first and second detection units 1002,1004 detect the amplitude decline for checking signal.Thus, one Or no one of multiple electrical characteristics instruction detection units 1002,1004 check signal, and recognition unit determines route Section is potential to be damaged.Alternatively, check that signal can be the second inspection signal shown in curve graph 1010, so that electric signal Be mark and draw electric signal 1014 and 1018 rather than 1012 and 1016.
In the alternative embodiment of reference Fig. 6 description, wherein the system of inspection includes at least two application dresses being separated by It sets, but only includes a detection unit, it can be similar with curve graph 1010 along the electrical characteristics that route is monitored by detection unit It is shown in curve graph.For example, curve graph may include the electric signal 1012 and 1014 marked and drawed, wherein electric signal 1012 is represented by first Application apparatus (such as application apparatus 606A in Fig. 6) injects and by the detection unit in detection unit 1002(such as Fig. 6 616A) the first of detection checks signal, and electric signal 1014 is represented by the second application apparatus (such as application apparatus in Fig. 6 606B) injection and the second inspection signal detected by identical detection unit 1002.Using only electric signal 1012 and 1014( It is not that can determine the state of route using 1016 and plotting amplitude 1018), recognition unit yet.For example, time t0 and t2 it Between, both signals 1012 and 1014 are all constant, instruction detection unit 1002 the first and second inspection of reception with baseline value Both signals, therefore route segment is not damaged.Between time t2 and t4, the one or more that is monitored by detection unit 1002 First increasing degree of inspection signal of the electrical characteristics instruction more than baseline and subtracting in baseline the second inspection signal below By a small margin.Thus, during the period, detection unit 1002 only receives the first inspection signal and checks signal without receiving second (surmounting trace or negligible quantity), this instruction route segment may include electric short circuit.For example, the first application apparatus 606A exists with reference to Fig. 6 On electric short circuit on side identical with detection unit 616A, therefore first checks that signal is detected unit 616A and receives and with first Check that the amplitude of the associated electric signal of signal increases in baseline amplitude due to being formed by sub-loop by electric short circuit.However, On side second application apparatus 606B opposite with detection unit 616A on electric short circuit, therefore second checks signal in different sons Circuit cycle and not detected unit 616A reception, decline so as to cause signal 1014 is marked and drawed in the period amplitude.Finally, Between time t5 and t7, the one or more electrical characteristics instruction first and second monitored by detection unit 1002 checks signal The amplitude of the two all declines, therefore no one of inspection signal is detected unit 1002 and receives.Thus, route segment is potential to be damaged Bad, this causes open circuit circuit and explains not check any of signal by detection unit 1002.Alternatively, it detects Unit 1002 can be detection unit 1004 shown in curve graph 1010, so that electric signal is 1016 He of electric signal marked and drawed 1018 rather than 1012 and 1014.
In the alternative embodiment of reference Fig. 6 description, wherein the system of inspection is one comprising only one application apparatus and only A detection unit can be shown by detection unit along the electrical characteristics that route is monitored in the curve graph similar with curve graph 1010. For example, curve graph may include the electric signal 1012 marked and drawed, wherein electric signal 1012 is represented (such as is shown by application apparatus in Fig. 6 Application apparatus 606A) inject and be detected unit 1002(detection unit 161A for example shown in Fig. 6) detection inspection Signal.Using only electric signal 1012(rather than also it can determine road using 1014,1016 and plotting amplitude 1018), recognition unit The state of line.For example, between time t0 and t2, signal 1012 with baseline value be it is constant, this instruction detection unit 1002 connects It receives and checks signal, therefore route segment is not damaged.Between time t2 and t4, monitored by detection unit 1002 one or more The increasing degree of inspection signal of a electrical characteristics instruction more than baseline, this further indicates that route segment includes electric short circuit.Finally, Between time t5 and t7, the one or more electrical characteristics instruction monitored by detection unit 1002 is checked under the amplitude of signal Drop, therefore check that signal is not detected unit 1002 and receives.Thus, route segment is potential to be damaged, this causes circuit of opening a way.Alternatively Ground, detection unit can be the detection unit 616B for example shown in Fig. 6 of detection unit 1004(shown in curve graph 1010) And electric signal is to mark and draw electric signal 1018(application apparatus 606B as shown in Fig. 9 injection) rather than 1012.Thus, detection Unit can obtain close to application apparatus and mark and draw electric signal 1012 and 1018.For example, along the length of vehicle or Vehicular system with The application apparatus that detection device is separated by, which can lead to, marks and draws electric signal 1014 or 1016, and the two passes through the damage of route in the system of inspection Show that amplitude declines when both bad section and electric short circuit.Detection unit marks and draws answering for one in signal 1014,1016 with offer It is useless with the two state aspects for distinguishing route are arranged in being separated by between unit, unless for example being monitored in conjunction with other Electrical characteristics, such as phase or modulation are explained and mark and draw signal 1014 or 1016.
Figure 13 is the stream for the embodiment for checking the method 1100 of the route travelled by Vehicular system from Vehicular system Cheng Tu.This method 1100 is in combination with Vehicular system described herein and/or checks that one or more embodiments of system use.It is standby Selection of land, method 1100 can be realized together with another system.
At 1102, by the transmission line of the first and second inspection signal electrical pumpings to the route travelled by Vehicular system In.First checks that the first vehicle injection of Vehicular system can be used in signal.Second inspection signal can be used the first vehicle first Vehicle is checked relative to injection first to be injected at the posteriorly or anteriorly position of the position of signal.Optionally, first check that signal can It is injected using the first vehicle, and second checks that the second vehicle injection in Vehicular system can be used in signal.By first and second Check that signal electrical pumping may include applying specified direct current, specified exchange at least one transmission line of route into transmission line And/or specified radiofrequency signal.First and second inspection signals can transmit in different transmission lines, such as opposite parallel lines Road.
At 1104, one or more electrical characteristics of route are monitored at the first and second monitoring positions.Monitoring position can In response to the first and second inspection signals are injected into transmission line and on the first vehicle.First monitoring position is relative to the It two monitoring positions can be closer to positioning before the first vehicle.Detection unit can be positioned at the first and second monitoring positions.It can The electrical characteristics of route are monitored at the first monitoring position along a transmission line;Position can be monitored second along different transmission lines Set the electrical characteristics of place's monitoring route.Optionally, it can convey and when believe the first and second inspections to the first and second monitoring positions The notice number being injected into route.The electrical characteristics of monitoring route may be in response to receive notice to execute.
At 1106, make about whether one or more monitored electrical characteristics indicate at two monitoring positions reception the One and second check both signals determination.For example, if two inspection letters are monitored in electrical characteristics at two monitoring positions Number, then two inspection signals recycle (being shown in FIG. 9) in conduction test circuit 912.Therefore, the circuit of test loop is complete 's.But if monitoring position in each monitoring only indicate inspection signal in one or no one electrical characteristics, The circuit of test loop can be by electrically destroying or electric short circuit influences.If electrical characteristics indicate to connect at two monitoring positions really It receives first and second and checks both signals, the stream of method 1100 can advance to 1108.
At 1108, vehicle continues along route running.The stream of method 1100 and then 1102 are proceeded back to, wherein first and Two inspection signals are again by injection transmission line, and method 1100 repeats.Method 1100 can weigh immediately when advancing to 1108 It is multiple, or before refilling inspection signal, waiting period, such as 1 second, 2 seconds or 5 seconds may be present.
Referring back to 1106, if electrical characteristics instruction does not receive two inspection signals, method at two monitoring positions 1100 prevalence enters 1110.At 1110, make about whether the monitored electrical characteristics of one or more indicate in the first monitoring Signal is checked there is only the first or second at position and there is only the determinations that another checks signal at the second monitoring position. For example, received electrical characteristics can indicate that there is only first to check signal at the first monitoring position, rather than second checks signal. Equally, received electrical characteristics can indicate that there is only second to check signal at the second monitoring position, rather than first checks signal. " instruction " checks that " presence " of signal means that received electrical characteristics comprise more than the pure threshold value of unique identifier as described herein Signal-to-noise ratio, unique identifier instruction are more than the corresponding inspection signal of electrical noise.
The determination can be used for distinguishing the instruction impaired electrical characteristics of route segment and instruction route segment is not damaged but can have The electrical characteristics of electric short circuit.For example, route can because first and second check that each place of the signal all not in monitoring position receives It is identified as potential being damaged due to destroying route (it causes to open a way).However, electric short circuit can also cause one or two monitoring Position does not receive two inspection signals, to potentially result in false alarm.Therefore, it is by electric short circuit and electrically broken to make the determination Bad block separates.
For example, believing if not receiving two inspection at any one when Vehicular system crosses route segment in monitoring position Number, electrical characteristics can indicate that route segment is damaged (for example, destruction).Alternatively, if monitoring monitoring at one in position There is only one checked in signal, which is damaged but includes electric short circuit for one or more electrical characteristics instructions.If The electrical characteristics monitored at another monitoring position indicate that the instruction can be reinforced there is only another inspection signal.In addition, if in vehicle The amplitude of the electrical characteristics monitored at the first monitoring position when system crosses route segment is monitored at the second monitoring position The inverse derivative of the amplitude of electrical characteristics may further indicate that non-damaging section of the route with electric short circuit.If monitored electrical characteristics instruction An inspection signal is only obviously received at the first monitoring position and only obviously receives another inspection at the second monitoring position Signal, then the prevalence of method 1100 enters 1112.
At 1112, route segment is identified as non-damaging but has electric short circuit.In response, the identification route comprising electric short circuit The notice of section can be conveyed and/or be stored in outside vehicle in the vehicle-mounted data library on Vehicular system.The position of electric short circuit can pass through by The position of vehicle at any time with monitoring position at monitor electrical characteristics monitored amplitude inverse derivative compared with and more accurately It determines.For example, from two monitoring positions of electric short circuit have equidistant when the inverse derivative monitoring of amplitude is equal.Location information It can be obtained from the position determination unit (such as GPS device) being located on vehicle or outside vehicle.Section is being identified as to have electricity short Lu Hou, at 1108, Vehicular system continues along route running.
Now referring back to 1100, if monitored electrical characteristics do not indicate only obviously to receive one at the first monitoring position A inspection signal and second monitoring position at only obviously receive another inspection signal, then the prevalence of method 1100 enters 1114.At 1114, route segment is identified as being damaged.Because two monitoring positions all do not receive instruction and check in signal at least One electrical characteristics, vehicle are likely to just cross the electrical destruction in route, even if not being to conduct all inspections along test loop Signal, this also prevents major part.The damage section of route may be provided between the specified wheel shaft of the first vehicle, the specified wheel shaft base The end of test loop is limited in the one or more electrical characteristics monitored at the first and second monitoring positions.Know by route segment After Wei not being damaged, prevalence enters 1116.
At 1116, it is damaged in response to identification route segment to initiate response action.For example, vehicle (such as pass through control Unit and/or recognition unit) it can be configured to make to move other one or more Vehicular system routes of slack-off, automatic notice automatically It damages section and/or automatic request checking and/or repairs the damage section of route.Caution signal can be passed to vehicle external position, configuration At the damage section for notifying recipient's route.The repairing signal that the damage section of route is repaired in request can also be conveyed outside vehicle.Warning and/ Or repairing signal can be conveyed by least one of control unit of the vehicle positioning on vehicle or recognition unit.In addition, response Movement may include by obtaining during the time that the first and second inspection signals are injected into route from position determination unit The location information of vehicle determines the position of the damage section of route.The electrical destruction position calculated in route can be used as warning and/ Or the part of repairing signal is passed to vehicle external position.Optionally, response action (such as send caution signal, repair signal and/or Change the operation setting of vehicle) at least by the vehicle-mounted vehicle operator on vehicle or the dispatcher of facility outside vehicle can be located in It initiates manually.
Except the one or more embodiments for the checking of routing system for using the damage section as described herein for detection route Except or as it is alternative, one or more embodiments of checking of routing system can be used for determining to be arranged about checking of routing system The location information of the vehicle at place.The location information can be comprising vehicle current setting on which route of several different routes Determination, the determination of vehicle location on route, vehicle along route driving direction and/or vehicle along the speed where route running Degree.
Figure 14 is the schematic diagram of the embodiment of the inspection system 900 in vehicle 902 on route 904 when driving vehicle 902 Show.Although only showing two wheel shafts 1400, " wheel shaft 3 " and " wheel shaft 4 " in 1402(Figure 14 in Figure 14), vehicle 902 can wrap Wheel shaft containing different number and/or the wheel shaft in addition to the third and fourth wheel shaft of workable vehicle 902.
Route 904 can be by conducting track 614(described above for example, track 614A, 614B) it is formed.904 energy of route Enough includes one or more frequency tuning branches 1404, is extended between conducting track 614A, 614B.Frequency tuning branch 1404 can in track 614A, 614B with branch 1404 be tuned to frequency conduction electric signal route 904 rail Conduction path or short circuit are formed between road 614A, 614B.For example, branch 1404 shown in Figure 14 is tuned to the frequency of 3.8kHz Rate.With 3.8kHz frequency, along track 614A conduction electric signal will be also transmitted to by branch 1404 track 614B(and/or This signal can be transmitted to track 614A from track 614B by branch 1404).However, having other frequencies (for example, 4.6kHz Or another frequency) electric signal will not be branched out 1404 conduction.Therefore, with branch 1404 be tuned to frequency (referred to as adjust Harmonics rate), by " Tx2 " in applying unit 908B(Figure 14) be injected into the signal of track 614A will along comprising track 614A, The circuit loop or path of wheel shaft 1400, track 614B and branch 1404.The signal is detected in unit 910B(Figure 14 " Rx1 ") it detects.Similarly, there is tuned frequency, by " Tx1 " in applying unit 908A(Figure 14) it is injected into track 614B In signal will be along circuit loop or path comprising track 614B, wheel shaft 1402, track 614A and branch 1404.One In a embodiment, the detectable signal with different frequency of one or more of detection unit.
The signal in track 614A is injected by edge with the frequency in addition to tuned frequency and by applying unit 908B Comprising track 614A, wheel shaft 1400, track 614B and wheel shaft 1402 but not comprising the circuit loop or path of branch 1404. Similarly, have frequency in addition to tuned frequency and the signal in track 614B is injected by applying unit 908A will be along packet 614B containing track, wheel shaft 1402, track 614A and wheel shaft 1400 but the circuit loop or path for not including branch 1404.It adjusts The humorous branch to multiple frequencies (such as 3.8kHz and 4.6kHz or frequency range comprising 3.8kHz and 4.6kHz) believes conduction Number.For example, be tuned to the branch of the frequency range comprising both 3.8kHz and 4.6kHz will be conducted between track 614A, 614B The signal of frequency with 3.8kHz or 4.6kHz.
One or more frequency tuning branches can calibrate the vehicle along route running in specified location setting across route Position.Frequency tuning branch can be read to limit the specific position of vehicle on route by inspection system described herein. This can allow for when combining with the position determination system of vehicle (for example, GPS receiver, wireless transceiver etc.) The accurate alignment of vehicle location, and can be when using dead reckoning techniques and/or when another localization method is unavailable Increase the accuracy of vehicle location.The detection of frequency tuning branch, which also can be used in determining that vehicle is currently located in, several does not go the same way On which route of line.
Inspection system is able to use multiple and different frequencies and comes for the route below damage test vehicle.By on route Place the element (such as frequency tuning branch) that one in frequency or combination makes a response and along the spacing of route Plan difference place this class component, code can be generated and transported by using in a manner of economical and reliable about vehicle specific position Information.
Figure 15 diagram is shown in FIG. 14 in Vehicular system along route 904(according to an example) it when driving can be by vehicle system The electrical characteristics 1500(of the route of inspection system monitoring on system is for example, electrical characteristics 1500A, 1500B) and electrical characteristics 1502( Such as, electrical characteristics 1502A, 1502B).Electrical characteristics 1500,1502 and representative are along the time of route 904 or the trunnion axis 1504 of distance With the vertical axis for the amplitude (as detection unit 910A, 910B as shown in Figure 14 measures) for representing electrical characteristics 1500,1502 1506 show together.Electrical characteristics 1500,1502, which are represented, is injected into the track 614(of route 904 in Figure 14 by applying unit 908 Show) in the first and second signals amplitude, such as by detection unit 910A, 910B in Vehicular system in frequency tuning branch It is detected during being travelled on 1404.
Applying unit 908A can inject the first signal, have not be branch 1404 tuned frequency (or in branch Outside 1404 frequency tuning range) frequency.Applying unit 908B can inject second signal, with branch 1404(or In the frequency tuning range of branch 1404) tuned frequency.Detection unit 910A can pass through track in the first and second signals 614A detects their amplitude when being transmitted to detection unit 910A and detection unit 910B can be logical in the first and second signals Cross the amplitude that them are detected when track 614B is transmitted to detection unit 910B.Electrical characteristics 1500A is represented such as by detection unit 910B The amplitude and electrical characteristics 1500B of the first signal (nonresonant frequency signal) of detection are represented as being detected detection unit 910A The amplitude of first signal.Electrical characteristics 1502A is represented such as the second signal (tuned frequency signal) detected by detection unit 910B Amplitude and electrical characteristics 1502B represent the amplitude such as by the detection unit 910A second signal detected.
The instruction of time t1 Vehicular system driving direction 1406 shown in Figure 14 when driving wheel shaft 1400(for example, drawing Guide shaft) when pass through branch 1404.Time t2 instruction Vehicular system along driving direction 1406 when driving wheel shaft 1402(for example, Driven shaft) when pass through branch 1404.Period comprising time t1 and t2 and in-between represents when branch 1404 sets It sets between wheel shaft 1400,1402.
Before wheel shaft 1400 crosses branch 1404 (for example, before time t 1), the first and second signals pass through by taking turns Circuit that the section of axis 1400,1402 and the track 614 extended from wheel shaft 1400,1402 and in-between is formed conducts.Cause This, the amplitude of electrical characteristics 1500,1502 do not substantially change (for example, electrical characteristics 1500,1502 can be had not been changed in amplitude or Amplitude change can be caused by noise or external interference).
However, forming different circuits to the first and second different signals, this takes when wheel shaft 1400 passes through branch 1404 Certainly in signal frequency.For example, for the first signal (nonresonant frequency signal), the first signal transduction to detection unit 910A, The circuit that 910B is passed through does not change.Therefore, the amplitude of electrical characteristics 1500A, 1500B is not substantially change.For the second letter Number (tuned frequency signal), branch 1404 conduct second signal and form smaller different circuits.Conduct the electricity of second signal Road include wheel shaft 1400, branch 1404 and extended to from wheel shaft 1400 branch 1404 track 614 section.For second signal The circuit can also prevent second signal to be transmitted to detection unit 910A.Smaller circuit comprising branch 1404 can prevent second Signal reaches detection unit 910A and is detected by it.
Detection unit 910B is in time t1 or the increase of detection second signal nearby, such as the electrical characteristics as shown in Figure 15 Indicated by the increase of 1502A.The increase can be by extending to branch 1404 by wheel shaft 1400, branch 1404 and from wheel shaft 1400 The section of track 614 be formed by the reduced electrical impedance in circuit and cause.For example, because the circuit ratio does not include branch 1404 Circuit it is shorter, electrical impedance can be smaller.
There is branch 1404 since circuit is formed, detection unit 910A can be no longer able to the second letter of detection after time t1 Number.Being formed, there is the circuit of branch 1404 can prevent second signal from conducting in track 614A.Detection unit 910A is detectable Second signal reduces or eliminates, as by represented by the reduction of time t1 electrical characteristics 1502B.
When vehicle moves in branch 1404, wheel shaft 1400 is mobile further from branch 1404.From wheel shaft 1400 to branch 1404 increase distance increases the size of the circuit comprising wheel shaft 1400 and branch 1404.Electrical characteristics 1502A conduction is passed through Circuit impedance increase from time t1 to time t2.Increased impedance can be such that second signal (is such as examined by detection unit 910B Survey) amplitude reduce.Therefore, the amplitude of the electrical characteristics 1502A detected by detection unit 910B is from time t1 to time t2 to be subtracted It is small.About detection unit 910A, because branch 1404 continues that second signal is prevented to be transmitted to detection unit 910A, electrical characteristics The amplitude of 1502B keeps reducing, as being shown in FIG. 15.
Once Vehicular system has moved in branch 1404 and branch 1404 is no longer between wheel shaft 1400,1402 (for example, after time t 2), second signal is conducted through such circuit again, it includes branch 1404 and by wheel shaft 1400,1402 and the section of the track 614 extended between wheel shaft 1400,1402 formed.Such as detected by detection unit 910B The amplitude of binary signal can return to the previously measured level of time t1.Because branch 1404 no longer prevent detection unit 910A when Between second signal is detected after t2, the value of electrical characteristics 1502B can increase existing horizontal before returning to time t1.
Inspection system can be analyzed two or more by frequency tune in electrical characteristics 1500A, 1500B, 1502A, 1502B The distinct of another branch opens in the detection of the damage section of the detection and route 904 of humorous branch 1404 and/or route 904. Destruction 922 in 904 middle orbit 614 of route can lead to the two or more signals such as detected by detection unit 910A, 910B 1012,1014,1016,1018 reduce during concurrent time, in the time for extending to time t7 from time t5 such as in Figure 12 It is shown during section.In contrast, only one in Vehicular system crosses branch in electrical characteristics 1500A, 1500B, 1502A, 1502B Reduce during 1404.Control unit and/or recognition unit can determine how many electrical characteristics 1500A, 1500B of some time, 1502A, 1502B reduce to determine that Vehicular system is in the damage section of route 904 or in 1404 uplink of frequency tuning branch It sails.Be not frequency tuning branch 1404 branch 916 cause in signal 1012,1014,1016,1018 it is two or more (or All) increase and/or reduce during crossing branch 916, such as in Figure 12 during from time t2 to the period of time t4 It shows.In contrast, only changed during crossing frequency tuning branch 1404 by the signal that single detection unit 910B is detected. Therefore, if changed by the signal that two or more detection units detect, the branch detected can not be frequency tuning point Road.If changed by the signal that same detection unit detects, but the signal detected by another detection unit does not change, then detects To branch can be frequency tuning branch.
In addition to detection is to the damage of route 904 or as it alternatively, inspection system described herein can also check electric spy Property 1500,1502 determines the much information about Vehicular system and/or route 904.As an example, control unit 206, 506 and/or recognition unit 220,520 can identify Vehicular system along which route 904 travel.Different routes 904 can be Different location and/or sequence have frequency tuning branch 1404.The position of branch 1404 and/or the sequence of branch 1404 are to route 904 can be uniquely, so that inspection system can determine Vehicular system along which route when detecting branch 1404 904 travelings.
For example, the first route 904 can have be tuned to first frequency the first branch 1404 and the second route 904 can have Have be tuned to second frequency the second branch 1404.Inspection system can be injected with one or more in first or second frequency A signal is to attempt to detect the first and/or second branch 1404.Detect one in the change in electrical characteristics 1502 or When multiple, inspection system can determine that Vehicular system travels in first or second branch 1404.If the system of inspection will have The electric test signal of first frequency be injected into route 904 and check system detection to electrical characteristics 1502A and/or 1502B In the similar signal of change change, inspection system can determine that Vehicular system crosses the first branch 1404.First route 904 can Memory 540(with the system of inspection is in fig. 5 it is shown that the memory such as control unit, recognition unit, and/or as conveyed To check system) in the first branch 1404 association so that inspection system determines vehicle system when detecting the first branch 1404 System is on the first route 904.
If the electric test signal with first frequency is injected into route 904 and checks that system is not examined by the system of inspection It measures the signal similar with the change in electrical characteristics 1502A and/or 1502B to change, inspection system can determine Vehicular system also The first branch 1404 is not crossed.Then inspection system can determine Vehicular system not on the first route 904.
If the electric test signal with second frequency is injected into route 904 and checks system detection by the system of inspection Change to the signal similar with the change in electrical characteristics 1502A and/or 1502B, inspection system can determine that Vehicular system is crossed Second branch 1404.Second route 904 can be associated with the second branch 1404, so that checking when detecting the second branch 1404 System determines Vehicular system on the second route 904.If the electric test signal with second frequency is injected by the system of inspection In route 904 and check that system is not detected the signal similar with the change in electrical characteristics 1502A and/or 1502B and changes, inspection The system of looking into can determine that Vehicular system does not cross the second branch 1404 also.Then inspection system can determine Vehicular system not On two routes 904.

Alphabetical A and B represent branch 1404 be tuned to different frequency.Although each sequence packet of the branch 1404 in table 1 Containing four branches 1404, alternatively, one or more of sequence may include the branch 1404 of different number.Although sequence is only wrapped Containing two different frequencies, optionally, one or more sequences may include multiple frequencies.
Inspection system, which can be tracked, to be detected used by different branches 1404 sequentially by Vehicular system to determine Vehicular system Which travelled along route 904.For example, if check system detection to be tuned to frequency B branch 1404, behind have be tuned to Another branch 1404 of frequency B, have below be tuned to frequency A another branch 1404, have below be tuned to frequency A point Road 1404 then checks on the 8th route 904 that system can determine that Vehicular system is listed above.

Route Branch sequence
9 A, 50m, B
10 A, 30m, B
11 A, 100m, A
12 B, 20m, A, 30m, A
Digital 50m, 30m for being listed between alphabetical A and/or B etc. represent be tuned to A or B frequency branch 1404 between Distance.Inspection system be able to detect that be tuned to different frequency branch 1404, detect it is suitable used by these branches 1404 The distance between sequence and branch 1404, to determine Vehicular system along which route running.
Determine that Vehicular system is travelled along which route 904 using the detection of one or more frequency tuning branches 1404 It can be useful for distinguishing the different routes 904 closely separated together to control unit 206,506.But some routes 904 that This close enough resolution ratio for making other positions determine system (for example, global positioning system, radio triangulation etc.) can be with Vehicular system can not be distinguished to travel along which of different routes 904.Vehicular system can not rely on this kind of sometimes Other positions determine system, for example, when Vehicular system tunnel, in valley, urban district etc. when driving.It is when other positions determine System can not determine Vehicular system on which route 904 when driving, with the associated frequency tuning branch 1404 of route 904 Detection can allow for inspection system to determine Vehicular system on which route 904.
In another example, control unit 206,506 and/or recognition unit 220,520 are able to use one or more The detection of branch 1404 is to determine Vehicular system along the position that route 904 positions.Different location along route 904 can be in different positions Set and/or sequence in have different frequency tuning branches 1404.The position of branch 1404 and/or the sequence of branch 1404 are to edge The position of route 904 can be uniquely, so that inspection system can determine Vehicular system along route when detecting branch 1404 The position of 904 positioning.
For example, along the first position of route 904 can have be tuned to first frequency the first branch 1404 and along route 904 second position can have be tuned to second frequency the second branch 1404.Inspection system can be injected with first or The signal of one or more of two frequencies is to attempt to detect the first and/or second branch 1404.Detecting electrical characteristics 1502 In change in one or more when, inspection system can determine that Vehicular system travels in first or second branch 1404. If the electric test signal with first frequency is injected into route 904 by the system of inspection and to check that system detection is arrived special with electricity Property 1502A and/or 1502B in the similar signal of change change, inspection system can determine that Vehicular system crosses the first branch 1404.It can be associated with the first branch 1404 in the memory 540 of the system of inspection so that detecting along the first position of route 904 When to the first branch 1404, inspection system determine Vehicular system along and associated first route 904 of the first branch 1404 position Set place.
If the electric test signal with first frequency is injected into route 904 and checks that system is not examined by the system of inspection It measures the signal similar with the change in electrical characteristics 1502A and/or 1502B to change, inspection system can determine Vehicular system also The first branch 1404 is not crossed.Inspection system then can determine Vehicular system no-fix with the first branch 1404 associated At position on one route 904.
If the electric test signal with second frequency is injected into route 904 and checks system detection by the system of inspection Change to the signal similar with the change in electrical characteristics 1502A and/or 1502B, inspection system can determine that Vehicular system is crossed Second branch 1404.It can be associated with the second branch 1404 along the second position of route 904 so that detecting the second branch 1404 When, inspection system determine Vehicular system with the position on the associated route 904 of the second branch 1404 at.If the system of inspection will Electric test signal with second frequency be injected into route 904 and check system be not detected with electrical characteristics 1502A and/or The similar signal that changes in 1502B changes, and inspection system can determine that Vehicular system does not cross the second branch 1404 also.It checks Then system can determine Vehicular system not at edge with the position on the associated route 904 of the second branch 1404.
It additionally or in the alternative, can be with the difference of two or more frequency tuning branches 1404 along the different location of route 904 Serial correlation.With as described above it is similar, with the detection with the branch 1404 along the associated sequence in the designated position of route 904 Inspection system can allow for determine Vehicular system along the position that route positions.

The other positions that the determination position of Vehicular system can be used for calibrating or updating Vehicular system determine system, such as the whole world Positioning system receiver, wireless transceiver etc..Some position determination systems can cannot mention after position determines system initialization For the position of Vehicular system.For example, after opening Vehicular system and/or position determination system, position determination system can cannot The position of Vehicular system is determined in the period of initialization in position determination system.The frequency tuning branch during the initialization Detection can allow for the position of Vehicular system determining Vehicular system during initialization.
Optionally, system can be examined for determining for detecting the failure of the humorous branch 1404 of frequency modulation in designated position Branch 1404 is damaged or has been removed.Because the position of frequency tuning branch 1404 is storable in the memory of Vehicular system In 540 and/or it is passed to Vehicular system, the failure of frequency tuning branch 1404 is detected for the specified location in branch 1404 Can be used to that inspection system branch 1404 is notified to be damaged and/or be removed.Inspection system and/or control unit then can Operator's damage of notice Vehicular system and/or the branch 1404 missed can cause communication unit to dispatch or send from trend The inspection, repairing or replacement etc. that facility sends signal to dispatch branch 1404.
