In addition, in Fig. 3, road junction control device 1 via wireless device 7 on terrestrial wireless base station 6 and vehicle and with controlled on vehicle
Device 8 processed is connected to be communicated, and but not limited thereto.Road junction control device 1 can also be through not shown ground side
Other devices such as strong point device and communicated with vehicle upper controller 8.In addition, road junction control device 1 may not be monomer
Device, but be assembled to the structure of the other devices of security personnel's signal control device etc..
Then, the processing for shortening the road junction Xining at road junction 3 to road junction control device 1 is illustrated.Fig. 4 is to indicate real
The road junction Xining for applying the road junction control device 1 that mode 1 is related to shortens the flow chart of processing.
Firstly, the vehicle upper controller 8 for being equipped on each train utilizes channel radio via wireless device 7 on vehicle in train 4,5
The terrestrial wireless base station 6 of letter to the ground sends the train chief of the train position information of this train that this train is grasped, this train
The train information that degree information and the train speed information of this train are constituted.Terrestrial wireless base station 6 will be received from train 4,5
Train information sent to the train information acquisition unit 11 of road junction control device 1.Train information acquisition unit 11 will be from ground
The train information for the train 4,5 that wireless base station 6 receives is exported to moment prediction section 13.Dress is controlled on the vehicle of train 4,5
It sets 8 and periodically sends train information.
Moment prediction section 13 is believed based on the train of the train 4,5 got via train information acquisition unit 11 from train 4,5
It train position information, train length's information included in breath and train speed information and is maintained at road junction and controls database
The road junction information at the road junction 3 in 12, to predict that the road junction of train 4,5 is reached through moment (step S1).
In moment prediction section 13, found out based on the road junction information according to road junction 3, from the train position of each train 4,5
Road junction arrival time can be predicted by setting limitation speed set in the path until position is arranged in the road junction at road junction 3, but can also
To utilize other methods.For example, in moment prediction section 13, control database speed limiting information and acceleration and deceleration in 12 at road junction
The information of degree information is carried out in the form of the driving mode set in the section on the setting position periphery at road junction 3 according to standard
In the case where holding, the road junction arrival time of each train 4,5 can also be predicted based on driving mode.Driving mode and institute above
Driving mode meaning used in the patent document 2 stated is equal is identical.
Moment prediction section 13 for road junction by the moment, by the headstock position to train shown in train position information with
Position of 3 opposite side of road junction plus the position after the train length as shown in train length's information as the most tail portion of train,
Therefore at the time of regarding the most tail portion of train at the time of by the way that the most tail portion of train is reached road junction 3 as by road junction 3, so as to benefit
It is predicted with method identical with road junction arrival time.
Then, timing calculation part 14 using the road junction of the train 4,5 predicted by moment prediction section 13 reach by the moment,
And be maintained at road junction control database it is in 12, reached according to road junction and calculated by constantly and indicate that road junction 3 blocks during
Blocking starts over used Slack Time when timing, starts over timing (step S2) to calculate blocking.As described above,
The timing for being advanced by Slack Time or so than road junction arrival time is set as blocking by timing calculation part 14 starts timing, will compare road junction
Timing by having postponed Slack Time or so constantly is set as blocking stop timing.
Timing calculation part 14 is confirmed whether there are the more trains (step S3) for passing through road junction 3.In timing calculation part 14, contracting
The control of the road junction Xining of short-track mouth 3 by more trains by preventing the blocking of each train from opening in the case where road junction 3
A part overlapping of road junction Xining shown in beginning stop timing, to extend the road junction Xining at road junction 3.Therefore, road
In mouth control device 1, the road junction Xining for shortening road junction 3 is not needed in the case where being one by the train at road junction 3
Control, but timing is started over based on blocking calculated for a train to control road junction 3.
Timing calculation part 14 (step S3 is "Yes") in the case where the train by road junction 3 has more, is then based on needle
To more trains, calculated blocking starts over timing, to confirm whether the road junction Xining at road junction 3 is greater than in road junction 3
The Xining threshold value (step S4) of defined.Timing calculation part 14 finds out more trains by method as discussed above in Fig. 2
Road junction Xining when by road junction 3.
Xining threshold value indicate 3 defined of road junction road junction Xining allowed band, consider road junction 3 in route
The traffic volume etc. of the highway of intersection, and set in the operational management side of train.Therefore, in road junction control device 1, even if more
Train by road junction 3 to compared with when a train passes through road junction 3 road junction Xining it is elongated, at road junction, Xining is not
In the case where greater than Xining threshold value, the also control without shortening the road junction Xining at road junction 3.
In the case where the road junction Xining at road junction 3 is greater than Xining threshold value, (step S4 is timing calculation part 14
"Yes"), the operation letter for arriving first train for first reaching road junction 3 is obtained from operation management system 2 via operation information acquisition unit 15
It ceases (step S5).Due to starting over known to timing from the blocking of calculated train 4,5, first the train that arrives first at arrival road junction 3 is
Train 4, therefore timing calculation part 14 obtains the operation information of train 4.Specifically, timing calculation part 14 obtains operation information
Portion 15 specifies the train to 2 request operation information of operation management system, is here train 4.Operation information acquisition unit 15 from
Operation management system 2 obtain by timing calculation part 14 specify train 4 operation information, the operation information that will acquire export to
Timing calculation part 14.
Timing calculation part 14 judges whether that the train 4 for making to arrive first train prolongs based on the operation information got for train 4
(step S6) late.Timing calculation part 14 according in the operation information got for train 4, table information is included from
The current delay that the information and traveling actual achievement information that Slack Time is travelled between the station that station before road junction 3 is risen are included
Even if the information of time and being judged as makes train 4 arrive the station of the next stop road junction arrival time delay at road junction 3
In the case where moment delay, being judged as can be such that the train 4 for arriving first train postpones.
For example, travelling between the station from the station before road junction 3, Slack Time is 20 seconds, the current delay time at stop is 5
In the case where second, current practical Slack Time is 20-5=15 seconds, even if therefore timing calculation part 14 be judged as and make to arrive first column
The road junction arrival time of the train 4 of vehicle is delayed to 15 seconds, and the next stop arrival time of train 4 will not postpone, to be judged as
The train for arriving first train 4 can be made to postpone within 15 seconds.On the other hand, it is travelled between the station from the station before road junction 3
In the case that Slack Time is 20 seconds, the current delay time at stop is 20 seconds, current practical Slack Time is 20-20=0 seconds, because
If this timing calculation part 14 is judged as the road junction arrival time delay for making to arrive first the train 4 of train, the next stop of train 4 is reached
Moment delay, so that being judged as cannot be such that the train 4 for arriving first train postpones.
Timing calculation part 14 is determined in the case where being judged as that the train 4 for making to arrive first train postpones (step S6 "Yes")
Inhibition arrives first the speed (step S7) of the train 4 of train.Timing calculation part 14 based on the blocking of train 4,5 start over timing,
Slack Time and current delay time at stop are travelled between station from the station before the road junction 3, are determined with which kind of degree
Inhibit the speed of train 4.
There is the method using limitation speed into the method for the content that 4 transmission speed of train inhibits from timing calculation part 14.
Such as has and indicated so that train plays the side travelled until next specified place with 00 km/h of speed per hour from somewhere point
Method.In addition to this, there is the side using driving mode into the method for the content that 4 transmission speed of train inhibits from timing calculation part 14
Method.Such as have indicated so that train be directed to play from somewhere point through road junction until or reach the next stop until section according to
The method travelled according to the driving mode of generation.In addition, the method for these contents inhibited to 4 transmission speed of train is one
Example, also can use other methods.
Also, described above is utilized limitation speed, traveling mould via control instruction output section 16 by timing calculation part 14
Method of formula etc. inhibits to issue instruction to the train 4 for arriving first train together come the information and speed for carrying out the content of speed inhibition
(step S8).Specifically, timing calculation part 14 issues the information and speed for the content that speed inhibits to control instruction output section 16
Degree inhibits instruction, issues and is indicated so that the information and speed of the content that speed inhibits inhibit instruction defeated to control instruction output section 16
Out to train 4.Control instruction output section 16 is based on the instruction from timing calculation part 14, by the letter of the content inhibited comprising speed
Breath and speed inhibit the control instruction including instruction to be exported to train 4.
In train 4, onboard in control device 8, if via wireless device 7 on terrestrial wireless base station 6 and vehicle from certainly
Road junction control device 1 receives the instruction that speed inhibits, then the driver of train 4 makes train 4 according to the speed for being contained in control instruction
The content of inhibition is spent to travel.
As a result, in road junction control device 1, even if can postpone in the road junction arrival time for making the train 4 for arriving first train
When the next stop arrival time of train 4 will not be made to postpone, when the road junction arrival time of train 4 being made to postpone to block to shorten road junction
Between.
Road junction control device 1 is judged as that no more trains pass through (step in the case where road junction 3 in timing calculation part 14
S3 is "No"), the road junction Xining at road junction 3 (step S4 is "No") in Xining threshold value situation below is judged as
In the case where postponing the train 4 for arriving first train (step S6 "No"), terminate the control for shortening road junction Xining.
In addition, in road junction control device 1, even if making road junction arrival time being judged as the train 4 for arriving first train
When delay, next stop arrival time will not postpone, postpones train 4 postpone the road junction arrival time of train 4, shorten road junction
3 road junction Xining, but road junction Xining can also be shortened by other methods.In general, train 4,5 is relative to row
Sailing limitation speed specified in route has surplus, i.e., is travelled with limiting speed or less.Road junction control device 1 is according to road junction
The Slack Time travelled between the station that station before 3 is risen and the relationship between the current delay time at stop, by place described above
Reason be judged as can not make the train 4 for arriving first train postpone in the case where, as long as train 4 during driving to the next stop in can
It, then also can be can contract by being travelled using limiting speed as upper limit promotion speed so as to shorten the required time until the next stop
The time degree of short required time come make the train 4 for arriving first train postpone so that the road junction arrival time of train 4 postpone.
Here, the hardware configuration of the partial structurtes for the block diagram for realizing road junction control device 1 shown in Fig. 3 is illustrated.
Fig. 5 is the figure of the hardware configuration for the road junction control device 1 for indicating that embodiment 1 is related to.In road junction control device 1, moment prediction
Portion 13 and timing calculation part 14 (Random Access Memory: are deposited by being stored in by the execution of processor 51 by RAM at random
Access to memory), the program of each structure in the memory 52 of compositions such as ROM (Read Only Memory: read-only memory)
To realize.Train information acquisition unit 11, operation information acquisition unit 15 and control instruction output section 16 by processor 51 by being held
The program of each structure that row is stored in memory 52 and come together to realize with communicator 53.Road junction, which is controlled database, 12 to be passed through
Memory 52 is realized.Processor 51, memory 52, communicator 53 are connected by system bus 54.The control device 1 at road junction
In, multiple processors 51 and multiple memories 52 can synergistically execute the function of each structure shown in each block diagram.In road
In mouth control device 1, although can realize using hardware configuration shown in fig. 5, times in software or hardware also can use
It is a kind of to be installed.
As described above, according to the present embodiment, in road junction control device 1, calculate train 4 in road junction 3,
5 blocking start over timing, as blockings for calculating train 4,5 start over timing as a result, road junction 3 road junction resistance
In the case that the disconnected time is greater than defined Xining threshold value, the operation information for first reaching the train 4 at road junction 3 is obtained, is being judged
Even if when to make also not postpone the road junction arrival time delay of train 4, next stop arrival time, determining to inhibit train 4
