Specific embodiment
Specific embodiment of the invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that this place is retouched
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to limit the invention.
Fig. 1 be the present invention provide Train Detection and Identification equipment block diagram, as shown in figure 1, the equipment include receiver and
Controller.Wherein, receiver is used for the initial velocity of siding-to-siding block length, train acceleration and the train for receiving each speed restrictive block
With the limitation speed in each speed restrictive block；Controller is used to calculate train in the lazy of each speed restrictive block according to limitation speed
Scanning frequency degree so that when being run between the station of the train obtained according to siding-to-siding block length, train acceleration, initial velocity and the coasting speed
Between in the range of the scheduled time, and according to the coasting speed control for being calculated train operation.
Wherein, in the process of running often by multiple websites, the circuit between each two website is referred to as one to train
Speed limit section, due to reasons such as landform, each speed limit section can include one or more speed restrictive blocks again, include for a speed limit section
One situation of speed restrictive block, it is readily appreciated that the limitation speed in speed limit section is identical, multiple is included for a speed limit section
The situation of speed restrictive block, the limitation speed of each speed restrictive block is differed.Generally, speed restrictive block is according to limitation speed
Difference can be divided into arch, lower arch, it is upper it is stepped, under stepped four kinds of Interval Types, as shown in Fig. 2 Fig. 2 is the present invention carrying
The limit section classification diagram of confession.
When train is from a website, initial velocity is 0, before such case appears in launch train or is started
Carry out run time between computer installation simultaneously, certainly, if controller is to start run time between computer installation in train travelling process,
So initial velocity is just the current speed of service of train.
Wherein, train acceleration is a vector, and when train accelerates, the train acceleration is on the occasion of in train deceleration
When, the train acceleration is negative value.
Run time is usually that will be calculated at interval of a period of time between the station of controller calculating train described above
Once, it should be appreciated that assuming that the scheduled time scope of whole speed limit section is 20 minutes to 22 minutes, if in train operation
It it is 15 minutes to the spent time in the case of half, this represents that train is too slow in the speed of the first half speed limit section, so meter
Calculation obtain train later half speed limit section coasting speed will than calculated before launch train later half speed limit section
Coasting speed is fast, because so just can guarantee that run time was in the range of the scheduled time between station.
In order to prevent train from exceeding the speed limit, the limitation speed of each speed restrictive block be respectively the maximal rate of each speed restrictive block with
The difference of speed safe clearance, those skilled in the art can sets itself speed safe clearance as needed.
Wherein, controller is additionally operable to pass through two points according to the limitation speed and initial value set in advance of each speed restrictive block
Method iterative calculation obtains coasting speed of the train in each speed restrictive block.That is, calculating coasting by dichotomy iteration
Speed, according to the coasting speed being calculated and with reference to siding-to-siding block length, train acceleration, initial velocity come between the station for calculating train
Run time, until run time is in and just stops iterative calculation in the range of the scheduled time between the station for being calculated, and according to being counted
The run time between station calculated is in coasting speed corresponding in the range of the scheduled time to control the operation of train.Coasting speed
Be train in the non-acceleration of speed restrictive block, the travel speed in non-decelerating phase, for example, train is in a row for speed restrictive block
Speed is sailed to accelerate since 0, it is finally out of service with travel speed as 0, then the train accelerates up to reaching coasting since 0
Speed, is decelerated to 0 again when near terminal, and in this case, coasting speed is exactly the maximal rate of the speed restrictive block.
It is described in detail by dichotomy iterative calculation coasting speed to described above below.
Fig. 3 be the present invention provide most short station between run time the schematic diagram of operation curve 20, in figure 3, A station B station
It is a speed limit section 10, speed limit section 10 includes 5 speed restrictive blocks, respectively the 1st speed restrictive block, the 2nd speed restrictive block, the 3rd limit
Fast interval, the 4th speed restrictive block, the 5th speed restrictive block, are identified with 1,2,3,4,5 respectively in figure 3.If it is desired to obtain most
Run time between short station, its speed of service should just keep maximum, however, in order to ensure safety, limitation speed V herecx(x
The mark of speed restrictive block is identified, for example, Vc1Represent the limitation speed of the 1st speed restrictive block) should be guaranteed that one and limitation speed between
Individual speed safe clearance △ V.In Fig. 3 and other embodiments of the invention, when train needs to carry out acceleration-deceleration, with maximum
Acceleration VmaxWith maximum deceleration VminAccelerated and slowed down.
If train is run with the operation curve 20 of run time between the most short station shown in Fig. 3, then train is stood and B in A
Run time between standing is also most short, i.e., run time between most short station, if however, run time is still big between the most short station
In the upper limit of scheduled time scope, then do not had iteration space, train is just bent with the operation of run time between the most short station
Line 20 runs.If however, run time is in the range of the scheduled time (i.e. more than or equal to scheduled time model between the most short station
The lower limit for enclosing and the upper limit for being less than or equal to scheduled time scope), it is not required that it is iterated, train is just transported between the most short station
The operation curve 20 of row time runs.
If however, lower limit of the run time less than scheduled time scope between the most short station, then be accomplished by train
Coasting speed is iterated calculating.Fig. 4 is the schematic diagram of operation curve 30 between station after the first time iteration that the present invention is provided, the
In an iteration, maximum Vmax=Vcx, minimum value Vmin=0 (it will be appreciated by those skilled in the art that in the first iteration
Minimum value may not be 0, and design parameter can be according to actual conditions sets itself), the coasting speed that first time iteration is calculated
Degree Vcx'=(Vmax+Vmin)/2=Vcx/2.According to operation curve 30 between the first stop being calculated come run time between computer installation,
In the case that run time was in the range of the scheduled time between the station, iteration terminates, and controller is according to the coasting speed for being calculated
Operation curve 30 controls the operation of train between degree and thus obtained first stop.
If upper more than scheduled time scope according to run time between the station that operation curve between first stop 30 is calculated
Limit, then be accomplished by carrying out second iteration, in second iteration in this case, maximum VmaxKeep constant, still
It is Vmax=Vcx, minimum value Vmin=Vcx', the coasting speed V that second iteration is calculatedcx"=(Vmax+Vmin)/2=(Vcx+
Vcx') run time is more than between/2, Fig. 5 shows the station being calculated according to operation curve between first stop 30 of present invention offer
The schematic diagram of operation curve 40 between the station obtained after second iteration is carried out in the case of the upper limit of scheduled time scope.
If according to run time between the station that operation curve between first stop 30 is calculated less than under scheduled time scope
Limit, then be also required to carry out second iteration, in second iteration in this case, maximum Vmax=Vcx', minimum value
Keep constant, be still Vmin=0, the coasting speed V that second iteration is calculatedcx"=(Vmax+Vmin)/2=(Vcx’+0)/2
=VcxRun time is less than between '/2, Fig. 6 shows the station being calculated according to operation curve between first stop 30 of present invention offer
The schematic diagram of operation curve 50 between the station obtained after second iteration is carried out in the case of the lower limit of scheduled time scope.
In the case where speed limit section includes multiple speed restrictive blocks, for the first adjacent speed restrictive block and the second speed limit area
Between, the tip speed of the first speed restrictive block is the top speed of the second speed restrictive block, and the tip speed or the top speed are not
First speed restrictive block adjacent more than this and the limitation speed of any speed restrictive block of the second speed restrictive block, so, by Fig. 3 extremely
If Fig. 6 can be seen that the limitation speed of the limitation speed of the first speed restrictive block less than the second speed restrictive block, then train is from the
The accelerator that the coasting speed of one speed restrictive block accelerates to the coasting speed of the second speed restrictive block is entered in the second speed restrictive block
It is capable, if however, the limitation speed of the first speed restrictive block more than the second speed restrictive block limitation speed, then train is from first
The coasting speed reduction of speed restrictive block to the moderating process of the coasting speed of the second speed restrictive block be to be carried out in the first speed restrictive block
's.
In train travelling process, iterative process described above will carry out one at interval of a time cycle
It is secondary, for example, just carrying out an iteration calculating at interval of 10 seconds.
Train from A stations drive to B station station between operation curve there is following 4 kinds of situations：
(1) from A station startups, stood to B and stopped, that is, it is 0 startup, speed when stopping to B stations to be stood with initial velocity from A
Spend is 0；
(2) from A station startups, stand not parking to B, that is, be 0 startup from A stations with initial velocity, do not stop to B stations,
Speed at B stations is not 0；
(3) stood to B and stopped with the speed more than 0 from A stations, that is, train not is 0 in the speed that A stands, to B stations
Speed during stopping is 0；
(4) stand not parking to B with the speed more than 0 from A stations, that is, train not is 0 in the speed that A stands, to B
Stand and do not stop, the speed at B stations is not 0.
The calculating process of ruuning situation is similar between 4 kinds of stations described above, differs only in speed or row that train is stood in A
Car is different in the speed that B stands.
It is given below with train from A stations, the embodiment of the iterative calculation carried out at S1 kilometer posts, Fig. 7 is

The row time is Tg, current train speed (train speed at S1 kilometer posts) is Vs, when train needs to carry out acceleration-deceleration,
With peak acceleration VmaxWith maximum deceleration VminAccelerated and slowed down.Train drives to the scheduled time model at B stations from A stations
Enclose is more than or equal to Tp-△TeAnd less than or equal to Tp+△Te, so, train drives to the scheduled time scope at B stations from S1
It is more than or equal to Tp-△Te-TgAnd less than or equal to Tp+△Te-Tg, in the embodiment shown in fig. 7, train does not stop to B stations
Car.After first time iterates to calculate, the time stood from S1 to B for obtaining is Tf1, however, Tf1<Tp-△Te-Tg, so first
Secondary iteration result is unsatisfactory for requiring, after second iterates to calculate, the time stood from S1 to B for obtaining is Tf2, however, Tf2>
Tp+△Te-Tg, so second iteration result is unsatisfactory for requiring, after third time is iterated to calculate, what is obtained stands from S1 to B
Time is Tf3, Tp-△Te-Tg<=Tf3<=Tp+△Te-Tg, Tf3Meet the requirement of run time, stop iteration, train with Tf3
