Fig. 2 shows the structural schematic diagrams of light bulb line yard according to an embodiment of the present invention, as shown, existing in yard
Two light bulb lines, exist simultaneously two inflection points, and described two inflection points are respectively inflection point GD-1 and inflection point GD-2.If train is from downlink
Line 02111G sets out, direction downlink, and when GD-1 is passed through in minimum safe end, current of traffic can be switched to by down direction
Line direction；If train is from uplink 02014G, direction uplink, when GD-2 is passed through in minimum safe end, train operation side
Switch to downlink to by uplink.Since the static line data direction regulation of existing CBTC internal system is from left to right forward direction, because
This static topological linking relationship as shown in Figure 3, i.e. section or so linking relationship are as follows: left side downlink is 02001G-02003G-
02005G-02007G-02009G-02011G-02013G；Left side uplink is 02002G-02004G-02006G-02008G-
02010G-02012G-02014G；Right side downlink is 02111G-02113G-02115G-02117G-02119G-02121G-
02123G；Right side uplink is 02112G-02114G-02116G-02118G-02120G-02122G-02124G.Inflection point two sides
Sector chaining relationship equity, i.e. the section of inflection point two sides is upper one or next each other each other, is being arranged in CBTC system
Vehicle can not determine next section of train driving when travelling to inflection point two sides section, mistake occurs in CBTC internal system, to column
Vehicle driving safety impacts.Illustratively, it is based on inflection point GD-1, when the maximum safe front end of train is in section 02123G, from area
Section 02123G is run to section 02124G, and current of traffic is downlink at this time, therefore section 02124G is section 02123G
Next section；But work as the maximum safe front end of train in section 02124G, runs from section 02124G to section 02123G, with
Up direction as defined in route in CBTC system is on the contrary, traffic direction or downlink at this time, therefore section 02123G is also section
Next section of 02124G, therefore, train can run to section 02124G from section 02123G with downlink, can also with downlink from
Section 02124G runs to section 02123G.It should be noted that train can automatic conversion fortune when the train tailstock passes through inflection point
Line direction.Similarly, by taking inflection point GD-2 and its two sides section 02001G and 02002G as an example, when the maximum safe front end of train exists
Section 02002G is run from section 02002G to section 02001G, and current of traffic is uplink at this time, therefore section 02001G
It is a upper section of section 02002G；But when the maximum safe front end of train is in section 02001G, from section 02001G run to
Section 02002G, at this time in traffic direction or uplink, with CBTC system down direction as defined in route on the contrary, therefore section
02001G is also a upper section of section 02002G, i.e. train can run to section 02001G from section 02002G with uplink,
Train can also be run from section 02001G to section 02002G with uplink.
Fig. 3 shows the process of the design method according to an embodiment of the present invention based on rail traffic light bulb line route
Schematic diagram.As shown, design method of the embodiment of the present invention based on rail traffic light bulb line route is first in CBTC system
Using the inflection point of light bulb line as a linked object in the inflection point two sides sector chaining relationship in system；It is then based on the chain
Relationship is connect, CBTC system finds the next or upper linked object that train is presently in section according to current of traffic.
Since the section of inflection point two sides must be adjacent two sections in train operation path, according to one of section one
Surely find another section.In the method for the embodiment of the present invention, CBTC system is found according to current of traffic and is arranged
The next or upper linked object process that vehicle is presently in section is as follows: when train be presently in the next of section or on
When one linked object is section, the section is the next section or a upper section that the train is presently in section；
When the next or upper linked object that train is presently in section is inflection point, the two sides section of the inflection point, institute are checked
It states train and is presently in one of section that section is inflection point two sides section, then another section is that the train is current
A next or upper section for locating section.Illustratively, train is located at section 02001G, the upper link of section 02001G
Object is inflection point GD-2, checks and finds that inflection point GD-2 two sides section is section 02001G and 02002G, since train is currently located
In on section 02001G, therefore section 02002G is the upper section that train is presently in section 02001G.
Based on the method for the invention, CBTC system can effectively calculate train envelope.The calculating train envelope includes:
When train envelope is not across the inflection point, the direction of search, i.e. train minimum safe can be uniquely determined according to current of traffic
End to the envelope between maximum safe front end is scanned for by the direction of search of current of traffic.At this point, train envelope meter
It calculates consistent with situation when no light bulb line；When train envelope is across in the inflection point, train envelope is divided into two parts: a part is
To the envelope between inflection point, another part is inflection point to the packet between the maximum safe front end of train for train minimum safe end
Network.Train minimum safe end to the envelope between the inflection point can uniquely determine the direction of search according to current of traffic,
Scanned for by the direction of search of current of traffic.And the inflection point to the envelope between the maximum safe front end of train just
The direction of search that the true direction of search and current of traffic determine on the contrary, the i.e. described inflection point between the maximum safe front end of train
Envelope be calculated as scanning for since the inflection point with the opposite direction of train operation, until finding the maximum safety of train
Section where front end.Wherein, the maximum safe front end of the train refers to the train location data value calculated according to positive error and pre-
The position range for determining the train front end that precision determines is greater than train front position according to the train location data value that positive error calculates
Estimated value；Train minimum safe end refers to that the train location data value calculated according to negative error and predetermined accuracy determine
Train end position range, according to negative error calculate train location data value be less than train terminal position estimated value.
Illustratively, if train envelope is across on inflection point GD-1, train minimum safe rear end is section 02121G, and train covers section
For 02121G, 02123G, 02124G and 02122G, and current of traffic is downlink, and the train envelope covering section calculates
Process is as follows: train envelope is divided into two parts: a part is train minimum safe end to the envelope between inflection point GD-1, in addition
A part is inflection point GD-1 to the envelope between the maximum safe front end of train.Train minimum safe end is between inflection point GD-1
Envelope can uniquely determine the direction of search, train downlink, according to operation direction it is found that downlink is positive according to current of traffic
To, therefore the next linked object positive according to section 02121G search, available next linked object are section
02123G；Forward lookup is carried out further according to section 02123G, obtaining next linked object is inflection point GD-1, checks search inflection point
The two sides section of GD-1 is section 02123G and 02124G, since search has obtained section 02123G in the previous step,
It is section 02124G that this step search, which obtains next linked object, i.e. section 02124G is next area of section 02123G
Section；Then due to inflection point GD-1 to the correct direction of search and current of traffic of the envelope between the maximum safe front end of train
The determining direction of search is on the contrary, train downlink, downlink then carry out reverse search according to section 02124G or uplink searched to be positive
Rope, obtain 02124G a upper linked object be section 02122G, thus obtain the train envelope be section 02121G,
02123G, 02124G and 02122G.
The method of the embodiment of the present invention also achieves CBTC system to current of traffic and semaphore direction, protection zone
The consistency in Duan Fangxiang and car stop protection direction is judged.Since semaphore is configured with static direction, arranged in judgement
When the consistency in vehicle traffic direction and semaphore direction, it is necessary first to the static direction equipping rules of specified signal machine；In particular,
When semaphore position is overlapped with the inflection point in light bulb line route, need specified signal machine direction be interior side's section route side
To the line direction of still foreign side's section.Fig. 4 is shown according to embodiments of the present invention to current of traffic and semaphore direction
The flow diagram that is judged of consistency.As shown, in embodiments of the present invention, semaphore protection is Nei Fangqu
Section, interior the first section of side are first sections in semaphore protection direction, and the semaphore is pre-configured in CBTC system
