Abstract
The present invention relates to a method for announcing line idle conditions through a shaft counting. In order to announce (F/B) idle or busy conditions of a section of roads (1, 2), values which are continuously obtained through shaft counting are no more transmitted to a counter (A1), which is replaced by transmitting only two signal codes (T2, T2<*>) corresponding to each train (Z). A first signal code (T2) during a first shaft of the train passes through and another signal code (T2<*>) after the train completely passes through are solved from the two signal codes of one counting point. If sensor signals or counting pulses of the next wheel don't appear in scheduled time, then the second signal code is transported. Differing from the prior art, the method of the present invention has special restrictions on data quantities which are transmitted and evaluated, and therefore, the cost can be greatly reduced particularly during data wireless transmission to a shaft counter. Furthermore, the transmission safety can be improved when using corresponding narrow bands to transmit wired data.

Description of drawings
Describe the present invention in detail below in conjunction with the embodiment that describes in the accompanying drawing.Shown in the accompanying drawing:
Fig. 1-the 4th, train by the surrounding time point cross the line idle in three highway sections and busy scenario and
Fig. 5 shows the effect of wheel sensor to affiliated pretreatment unit.
The specific embodiment
Track section shown in Fig. 1-4 is made of highway section 1-3; Train Z travels on this track section.Described three highway sections are by timing point ZP1-ZP4 boundary, and each is made of two staggered wheel sensores in part the track circuit switching device in these highway sections in known manner.Wheel sensor produces response to the wheel that crosses from the side, and the pretreatment unit VV1-VV4 that therefore is provided with on the timing point time of sending is gone up overlapping sensor signal.These pretreatment units convert the sensor signal of importing to can be for the count pulse relevant with travel direction of set evaluating apparatus A1-A3 use.The hypothesis that has set four axles among the figure with locomotive Z is corresponding, the pretreatment unit VV1 among Fig. 1 to the counting of four axles more than pretreatment unit VV3; The situation of rolling when illustrating that train is pushed ahead, and the calculating shaft value that will at every turn obtain join with the corresponding mark of pretreatment unit in.
Suppose among Fig. 1 that the primary shaft of train Z travels towards timing point ZP2 forward.When in identifying two sensors one is at first influenced or when the primary shaft that identifies locomotive influences two sensors on the timing point ZP2 simultaneously, the order pretreatment unit VV2 evaluating apparatus A3 in a highway section 2 backward sends signal code T2, provides this highway section thus the line is busy circular.Relevant with the type of code " a) at first effect, b) primary shaft " is, the form that code T2 also can current potential is sent to the highway section of crossing.In this case, the result of triggering code T2 is not corresponding with travel direction.The capital B of highway section below relevant highway section that the line is busy in the accompanying drawings circulates a notice of represented, and idle circular is represented with capital F.
Can be as shown in Figure 1, by existing data or electric power conductor between timing point and the evaluating apparatus but also can by one independently bus system carry out the transmission of signal code.Equally, also can carry out transmission over radio to signal code by communicating to connect of between timing point and distant place evaluating apparatus, setting up as required.Therefore, according to the multiplex needs that on the basis of safety, may occur, can carry out shunt and communicate to connect.
Can form by for example one of a permanent radio circuit that exists or temporary transient a plurality of open radiowave channel that is provided with does not in addition have the user to connect with open circuited code to communicate by letter.If in the total device of track, to wheel signal and ceases to be busy and the line is busy that circular is handled, then do not need to transmit described information to the calculating shaft value device in a distant place.
When the axletree in locomotive Z back crosses timing point ZP2, though pretreatment unit VV2 determines in the driving process the counting of the axle that crosses according to wherein sensor signal of input and determine this travel direction, its output is not transported to carrying out among the evaluating apparatus A1 and A3 that orbital surveillance is provided with.Pretreatment unit VV2 also calculates the size of the time gap between the adjacent axletree except the calculating shaft value of train and its travel direction of timing point ZP2 passed in calculating.Compare by time value with storage, the time point when pretreatment unit VV2 can determine to estimate train Z fully by timing point ZP2, wherein the maximum range value that allows between the adjacent axletree of Cun Chu time value and the slowest railway car is relevant.This situation is shown among Fig. 2.Can the train that one row travel at a slow speed be divided into a plurality of coupler (achsverbund) in logic according to time standard.Each train can be drawn more than two codes like this, but the time density of code is limited by the time value of storing.
By the train Z that identification is crossed fully, the evaluating apparatus A1 transmission signals code T2 in pretreatment unit highway section 1 rearwards
*, in this code, transmitted the calculating shaft value of determining.Evaluating apparatus A1 compares this calculating shaft value with the calculating shaft value that obtains from timing point ZP1.If consistent from two calculating shaft values that pretreatment unit obtains, then evaluating apparatus A1 will send the circular F of 1 free time of highway section.
Because pretreatment unit VV2 has stored with VV3 and has limited the timing point ZP2 in highway section 2 and the different calculating shaft values of ZP3, so keep the highway section 2 circular B that the line is busy of back.When highway section 2 was idle subsequently, pretreatment unit VV2 will be with signal code T2
*Form transmit the count value that it obtains to evaluating apparatus A3 after train Z crosses.It is unimportant in principle this situation when to occur.Therefore next fixed calculating shaft value can be stored among the pretreatment unit VV2, and send it in the evaluating apparatus according to the order of evaluating apparatus A3 after this, or the calculating shaft value result is sent to evaluating apparatus A3, and keep at this at previous time point.
Train continues to move forward in Fig. 3, and its primary shaft crosses timing point ZP3.Pretreatment unit VV3 under this point discerns the train axle, and sends relevant with it signal code T3 so that monitor fwd highway section 3 to evaluating apparatus A3.Evaluating apparatus A3 sends highway section, front 3 instruction that the line is busy in view of the above, and wherein this process is to carry out according to signal code, carries out unimportant after still the calculating shaft value of pretreatment unit VV3 and VV4 storage being compared.The highway section 2 circular B that the line is busy that keeps the back.
In Fig. 4, train Z is fully by timing point ZP3.Under the situation of the next count pulse of no future, pretreatment unit VV3 will send signal code T3 to evaluating apparatus A3
*Only need compare the timing point ZP2 in the highway section 2 of qualification back and the count results of ZP3 now.According to setting, this count results should be consistent with the calculating shaft value that obtains from affiliated pretreatment unit.Evaluating apparatus A3 provides the circular F of 2 free time of highway section of back in view of the above.By timing point ZP4 and evaluating apparatus A3 determine fully that at train the count results of pretreatment unit VV3 and VV4 keeps the fwd highway section 3 circular B that the line is busy before consistent.
If train Z is not fully by timing point ZP3, but by this timing point the time, stop, though pretreatment unit VV3 is not when the next sensor signal in future or count pulse arrive so, the calculating shaft value result's who will representative have obtained signal code T2
*Be transported among the evaluating apparatus A3.But circular and the no show of 2 free time of the highway section of back, this is because the different calculating shaft values of pretreatment unit VV2 and VV3 have been sent into evaluating apparatus A3.If train Z moves once again, then pretreatment unit VV3 will send the signal code T2 of renewal.But this does not have meaning because the still circular of two highway sections 2 and 3 the line is busy.If all the other axles of train are final by timing point ZP3, pretreatment unit VV3 will transmit another signal code T2 to evaluating apparatus A3
*, this is suitable for determining the consistent situation of calculating shaft value of pretreatment unit VV2 and VV3, at this moment can make highway section, the back circular of 2 free time.
If the train Z that stops is in the reversing sense motion, then will at first send highway section 2 and the 3 signal code T2 that the line is busy circulates a notice of equally by timing point ZP3 the time.When fully by timing point ZP3, pretreatment unit VV3 will carry signal code T2 to evaluating apparatus A3
*Evaluating apparatus A3 will compare from the calculating shaft value result that pretreatment unit VV3 and VV4 are transferred to it, and is emitted in the circular of the line idle in the highway section of crossing on the travel direction 3 when count results is consistent.If obtain the count results identical by timing point ZP2 and pretreatment unit VV2 fully when train continues to move forward, then can produce the highway section circular of 2 free time at this moment the earliest with pretreatment unit VV3.
In the above-described embodiments, think that the wheel sensor on each timing point all works to relative pretreater.But also can consider under situation about preferably timing point closely being provided with one by one, a plurality of timing points to be worked to a shared pretreatment unit.This can be the situation for example in multi-thread highway section the time.At this moment pretreatment unit can constitute like this, that is, its residing position can be with each evaluating apparatus that is used for monitoring each highway section of further delivering to from the count results of or another timing point under this timing point.
Fig. 5 represents the deployment scenarios of timing point ZP5-ZP8 on four rail sections 11,12,13,14.When timing point ZP5 and ZP8 act on the pretreatment unit VV5 that is provided with separately and VV8, timing point ZP6 and ZP7 will act on its shared pretreatment unit VV6/7.Timing point ZP5 and ZP8 also can control pretreatment unit VV6/7 in theory; But because must passing, the wheel sensor of timing point ZP5 and ZP8 just can guide shared pretreatment unit VV6/7 into below rail, so generally do not do like this.In order particularly when equipping again or changing the equipment that has existed, to avoid on roadbed, carrying out such work, be equipped with pretreatment unit separately for timing point ZP5 and ZP8 in the embodiment shown in fig. 5.
Suppose that in Fig. 5 pretreatment unit and not shown being used to are carried out the evaluating apparatus that the highway section monitors and be communicated with by radio circuit, wherein for the transmission signals code, each only with each under evaluating apparatus set up the short time and communicate to connect.At every turn by which with how many timing points are arranged to shared pretreatment unit generation effect, be actually structure by line facility and timing point on rail deployment scenarios and preliminary election is given.
Particularly, the count results that provides by pretreatment unit is provided on radio circuit if desired, then should preferably add additional information in the data of each transmission, the transmission data that this information can be unique identify the evaluating apparatus of reception to determine into it and these data are from where.Be the additional sign of the data of transmission then for each data source and each data sink.The data that preferably will at every turn transmit deposit evaluating apparatus in signal accepter sign then.In order at any time correct calculating shaft value to be compared mutually during idle circular in the highway section, further preferably be continuous numbering of data setting and/or timestamp, when from the pretreatment unit of a timing point to evaluating apparatus transmission data and/or when it receives data, can discern according to numbering and/or timestamp.By means of this timestamp can guarantee in evaluating apparatus, can unexpectedly not count old, to current insignificant calculating shaft value.
The method of the invention can be preferred for needing to monitor by the circulation calculating shaft value place of highway section ceases to be busy and engaged condition.Ad hoc proposal adopts the mode of transmission calculating shaft value on wireless link, and this is because only need carry out the data transmission of very short time according to instruction of the present invention.It is low that short time data transfer ratio permanent data is transmitted in energy aspect cost, and particularly this advantage is more obvious in the transmitting device of Driven by Solar Energy.Certainly, the present invention also is preferred for the occasion that timing point linked to each other with evaluating apparatus by supply line or bus line.In this case, not to resemble at present in the shortest time, a plurality of data of each actual count state representative to be sent into evaluating apparatus, but only train primary shaft and the data of last are listed in.This means that can transmit these data with lower data transfer rate (than the arrowband) and the time that prolongs, this produces beneficial effect to the transmission safety performance.
