Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the flow chart of track switch transponder message processing method embodiment mono-of the present invention, and as shown in Figure 1, the method for the present embodiment can comprise the following steps:
The transponder message that step 101, reception transponder send, described transponder message comprises transponder india D.
For instance, because each transponder (group) has an ID numbering, this numbering is unique within the scope of china railway, therefore, the transponder india D comprising according to the transponder report receiving, transponder india D data to storage are processed, and just can determine the corresponding region of transponder that train is about to sail into.
For instance, determine that according to transponder message train is about to sail into behind track switch region, can further determine the concrete condition of front track switch according to transponder message, and determine that according to the concrete condition of the row control ground installation of track switch train control on board equipment processes the transponder message tupe of transponder message, thereby make the train can be because speed limit bust causes braking when by track switch region.
Because according to transponder message tupe being sets according to the concrete condition of row controls ground installation, therefore, train control on board equipment is listed as control processing according to transponder message tupe to transponder message can make train when by track switch region, can not occur due to train control on board equipment and be listed as control ground installation to be not suitable with the situation that the trafficability characteristic of bringing is poor, easily cause train braking.
The track switch transponder message processing method of the present embodiment can make train when by track switch region, train control on board equipment can be listed as control according to the actual conditions of the row control ground installation in track switch region and process, thereby can effectively avoid causing unnecessary train braking, can, ensureing under the prerequisite of train operating safety, improve the efficiency of train operation.
Fig. 2 is the flow chart of track switch transponder message processing method embodiment bis-of the present invention, and as shown in Figure 2, the method for the present embodiment, on the basis of embodiment mono-, can comprise the following steps:
The transponder message that step 201, reception transponder send, transponder message comprises transponder india D.
Due to the step 101 of step 201 and embodiment mono-realize principle and technique effect is similar, repeat no more herein.
Step 202, determine the side line pattern of dispatching a car according to transponder message content.
For instance, in the time determining that according to transponder message train is about to sail track switch region into by side line, can determine that train control on board equipment processes the transponder message tupe of transponder message and should be the side line pattern of dispatching a car, thus the transponder message that can make train control on board equipment receive according to the concrete condition processing of the row control ground installation in track switch region.
If step 203 transponder message comprises temporary speed limitation information, and there is track data disappearance.
For instance, transponder group has been set up in existing Line for Passenger Transportation side line station track, and the transponder message that this transponder group sends has been described track circuit information, front line slope, static speed limit and the temporary speed limitation at exit signal rear.Due in this region, turnout, transponder group to rail-free circuit between exit signal is described, and will cause like this train control on board equipment transformation working pattern, makes train speed limit be reduced to 45km/h, so just easily causes train braking.
Step 204, the mode of operation of train control on board equipment is remained to Part I monitoring mode or Part II monitoring mode.
For instance, the mode of operation of train control on board equipment mainly contains standby mode, part monitoring mode, complete monitoring mode, visual pattern, bootmode, shunting mode and isolation mode etc.Train control on board equipment can be according to the transponder message transformation working pattern receiving, and carries out concrete row control action according to mode of operation.It should be noted that, above-mentioned mode of operation and the switch condition thereof of train control on board equipment belong to prior art category, and therefore, for preventing producing and obscure with the present invention, the present embodiment is not elaborated to above-mentioned mode of operation and switch condition.
Train control on board equipment occurs disappearance at the transponder message receiving, meeting entering part monitoring mode, wherein, the part monitoring mode of the train control on board equipment of CTCS-2-200C is divided into four kinds of Part I monitoring mode, Part II monitoring mode, Part III monitoring mode and Part IV monitoring modes.Prior art is according to transponder message deletion condition, in the time that train sails track switch region into by side line, because transponder group is described to rail-free circuit between exit signal, the working mode change of train control on board equipment is Part III monitoring mode, makes train speed limit reduce to 45km/h.And speed limit in the side line departure instructions of sending to train due to row controls ground installation is 80km/h, exceedes 45km/h and will trigger train braking action once train enters the speed in track switch region.
In order to prevent that train from carrying out unnecessary braking maneuver, in the time that train side line is dispatched a car, the mode of operation of train control on board equipment is remained Part I monitoring mode or Part II monitoring mode by the present embodiment, so just can make train receive after transponder message, be not Part III monitoring mode by working mode change, thereby make train speed limit can not reduce to 45km/h, so just can ensure can not trigger when train passes through track switch region unnecessary braking maneuver.
When step 205, track data are complete by the working mode change of train control on board equipment to monitoring mode completely.
For instance, after transponder message data that train control on board equipment is receiving is complete, can be complete monitoring mode by working mode change, so just can make train smooth and roll track switch region away from, thereby improve the efficiency of train operation and the comfortableness that passenger takes.
Fig. 3 is the flow chart of track switch transponder message processing method embodiment tri-of the present invention, and as shown in Figure 3, the method for the present embodiment, on the basis of embodiment mono-, can comprise the following steps:
The transponder message that step 301, reception transponder send, transponder message comprises transponder india D.
Due to the step 101 of step 301 and embodiment mono-realize principle and technique effect is similar, repeat no more herein.
For instance, in the time determining that according to transponder message train is about to sail into track switch region approaching side line, can determine that train control on board equipment processes the transponder message tupe of transponder message and should be side line and connect car pattern, thus the transponder message that can make train control on board equipment receive according to the concrete condition processing of the row control ground installation in track switch region.
Minimum carrier-frequency range and the maximum carrier-frequency range of step 303, calculating train location section.
For instance, in the prior art, when train driving is to track switch region, and will enter side line time, receive message that transponder group sends describe home signal rear 1306m and in fact without carrier frequency section,, in this 1306m section, only having front 490m is without carrier frequency section.The track circuit information that the carrier frequency that will receive the transmission of row control ground installation after track switch is crossed by train head is 2000Hz, now, causes the carrier frequency of train control on board equipment judgement and the carrier frequency of transponder message description inconsistent, thereby triggers the conventional maximum braking of train.
Under the premise that security is guaranteed, in order to prevent that train from carrying out unnecessary braking maneuver, in the time that train sails track switch region approaching side line into, minimum carrier-frequency range and the maximum carrier-frequency range of the present embodiment to train place section judges, carries out unnecessary braking maneuver with the train that prevents from causing because carrier frequency is inconsistent under inessential condition.
Preferably, step 303, is specifically as follows:
According to the minimum carrier-frequency range D of formula (1) and (2) calculating train location section
minwith maximum carrier-frequency range D
max,
D
min＝D_Min+D_Sen+v·Δt (1)
D
max＝D_Max+D_Sen+v·Δt (2)
Wherein, D_Max is the maximum home of train, and D_Min is train minimum safe position, and D_Sen is the distance between track circuit information receiving sensor and train head, v is the current speed of train, and Δ t is the time delay of the decoding of track circuit carrier frequency and communication.
The train control on board equipment of the present embodiment just can calculate the minimum carrier-frequency range D of train location section effectively like this
minwith maximum carrier-frequency range D
max, and fully take into account the time delay of the current speed of train and the decoding of track circuit carrier frequency and communication, can accurately calculate the minimum carrier-frequency range D of current train place section
minwith maximum carrier-frequency range D
max.
For instance, under the premise that security is guaranteed, in order to prevent that train from carrying out unnecessary braking maneuver, can in the actual transponder message of receiving, search the carrier frequency collection that meets minimum carrier-frequency range and maximum carrier-frequency range, just can judge by the carrier frequency collection finding whether the actual carrier frequency of receiving meets the requirement of carrier frequency collection.
Preferably, step 304 is specifically as follows:
Search the whole carrier frequency collection F between minimum carrier-frequency range and maximum carrier-frequency range according to formula (3),
Wherein, D_Start
ifor the starting point of i section track circuit in transponder message, D_End
ifor the terminal of i section track circuit in transponder message.
The train control on board equipment of the present embodiment just can effectively and accurately be searched the whole carrier frequency collection F between minimum carrier-frequency range and maximum carrier-frequency range like this.
For instance, train control on board equipment by the actual carrier frequency of receiving with compare by the carrier frequency collection finding, just can judge whether the actual carrier frequency of receiving meets the requirement of carrier frequency collection.
For instance, result after train control on board equipment compares according to the actual carrier frequency of receiving and carrier frequency collection, just can determine that whether carrier frequency is consistent, thereby under safing prerequisite, can not trigger because the carrier frequency of the carrier frequency of train control on board equipment judgement and the description of transponder message is inconsistent the conventional maximum braking of train.
Preferably, step 305 is specifically as follows: the carrier frequency f receiving if actual
0integrate result that F compares as f with carrier frequency
0∈ F, determines that carrier frequency is consistent.
For instance, the actual carrier frequency f receiving of train control on board equipment
0integrate result that F compares as f with carrier frequency
0when ∈ F, carrier frequency is judged as unanimously, can meets the needs of guarantee driving safety, can effectively prevent that train from carrying out unnecessary braking.
If
and current track circuit low frequency TC ≠ red signal H, determines that carrier frequency is consistent, otherwise determines that carrier frequency is inconsistent.
For instance, the actual carrier frequency f receiving of train control on board equipment
0the result comparing with carrier frequency collection F is
time, illustrate that now carrier frequency is inconsistent, therefore need further to judge whether the needs according to guarantee driving safety, determine whether train needs braking.In this case, current track circuit low frequency TC and red signal H that train control on board equipment further sends according to the row control ground installation receiving judge, if TC=H, illustrates that now problem has appearred in front track situation, now in order to ensure safety, need to process by carrier frequency is inconsistent, even if train is carried out conventional maximum braking.If TC=H, illustrates that now front track situation is no problem, train does not need to commonly use maximum braking and can meet the needs of safe driving, now carrier frequency can be defined as unanimously.
The track switch transponder message processing method of the present embodiment is in the time that train sails track switch region approaching side line into, can effectively prevent that the train causing because carrier frequency is inconsistent from carrying out unnecessary braking maneuver under inessential condition, can fully ensure train traffic safety, improve train operation efficiency and passenger's comfort level.
Fig. 4 is the flow chart of track switch transponder message processing method embodiment tetra-of the present invention, and as shown in Figure 4, the method for the present embodiment, on the basis of embodiment mono-, can comprise the following steps:
The transponder message that step 401, reception transponder send, transponder message comprises transponder india D.
Due to the step 101 of step 401 and embodiment mono-realize principle and technique effect is similar, repeat no more herein.
For instance, in the time determining that according to transponder india D train is about to sail track switch region into by side line, the transponder message tupe that can determine train control on board equipment processing transponder message should be side line region mode, thus the transponder message that can make train control on board equipment receive according to the concrete condition processing of the row control ground installation in track switch region.
If step 403 does not receive transponder message or the transponder message that receives exist abnormal, by transponder message according to Ligature processing.
For instance, in the prior art, because row are controlled the message finite capacity that the trackside transponder transmitting element in ground installation can be stored, therefore two groups of transponders in the message of transponder group, have been linked simultaneously, thereby easily cause transponder message disappearance, the Ligature of these two groups of transponders is reactionless.
The train control on board equipment of CTCS-2-200C is under complete monitoring mode; when limiting operation instruction or the side line driving instruction of receiving that row control ground installation sends; and front signal machine, for entering the station, when departures or route signal, can activate the transponder defencive function in side line region.Once activate this function, train control on board equipment will be taking the stop that calculated at that time as protection terminal, loses any transponder message and all can trigger the conventional maximum braking of train, until train is nullified this function after sailing out of protection terminal automatically in this interval.For guarantee driving safety, the present embodiment is not modified to transponder defencive function.
In the time that being about to sail track switch region into by side line, easily triggers by train the defect of conventional maximum braking for solving prior art; the present embodiment is retaining under the prerequisite of transponder defencive function; revise how processing transponder message dropping; if at train driving to protecting before terminal; train control on board equipment does not receive transponder message or the transponder message that receives exist abnormal, by transponder message according to coupled reaction processing.So just can effectively prevent from triggering due to transponder message disappearance the conventional maximum braking of train, thereby ensureing under the prerequisite of safe train operation, prevent that train from carrying out unnecessary braking maneuver, thereby improve train operation efficiency and passenger's comfort level.

For instance, in the time determining that according to transponder message train is about to sail into large size code channel and branches off and enter side line, the transponder message tupe that can determine train control on board equipment processing transponder message should be large size code channel trouble pattern, thus the transponder message that can make train control on board equipment receive according to the concrete condition processing of the row control ground installation in track switch region.
If step 503 is received the side line driving instruction that row control equipment in ground sends, and the transponder message receiving comprises the maximum Negotiation speed that allows of effective track switch side direction, gives tacit consent to train side line and passes through.
For instance, in the prior art, have successively two transponder groups in large size code channel trouble direction, the transponder message of first transponder group is described front directly to track data, and the transponder message of second transponder group is described side line track data.When train control on board equipment is during through the second transponder group, automatically vehicle-mounted data is updated to side line data, and the corresponding mobile authorization that recalculates.Receiving after the side line driving instruction that row controls ground installation sends, the mobile authorization terminal that train control on board equipment calculates is to the end of the first block section after track switch.
The general speed limit of side line driving segment ends of row control ground installation design is 80km/h, and being greater than the large size code channel trouble of 80km/h for side direction permissible velocity, it is 160km/h that the maximum of having described track switch side direction in the transponder message of the first transponder group allows Negotiation speed.And the speed limit that now train control on board equipment of CTCS-2-200C calculates according to the side line data of describing in the transponder message of the second transponder group does not reach 160km/h, so just cause speed limit bust.
For effectively addressing this problem, the row control ground installation of large size code channel trouble, in the time of the driving instruction of transmission side line and description large size code channel trouble data message, is opened large size code channel trouble end semaphore.If the train control on board equipment of the present embodiment in the side line driving instruction of receiving that row control equipment in ground sends, and the transponder message receiving comprises when effective track switch side direction is maximum allows Negotiation speed, acquiescence train side line passes through.The limiting operation now not calculating according to the side line data of describing in the transponder message of the second transponder group.In the side line driving instruction of not receiving that row control equipment in ground sends, or receive the side line driving instruction that row control equipment in ground sends, but do not receive and describe in the maximum transponder message that allows Negotiation speed of track switch side direction or the invalid situation of this transponder message, the limiting operation just calculating according to the side line data of describing in the transponder message of the second transponder group.So just can ensure the speed limit that train can not calculate according to the side line data of describing in the transponder message of the second transponder group, carry out unnecessary braking, thereby can effectively improve train operation efficiency and passenger's comfort level.
