Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
Fig. 1 is the block diagram of Train Detection and Identification equipment provided by the invention, and as shown in Figure 1, this equipment comprises receptor and controller.Wherein, receptor is for receiving the burst length of each speed restrictive block, train acceleration and the rate of onset of train and the limited speed at each speed restrictive block; Controller is used for calculating the coasting speed of train at each speed restrictive block according to limited speed, time of run between the station of the train obtained according to burst length, train acceleration, rate of onset and this coasting speed was within the scope of the schedule time, and the operation of train according to calculated coasting speeds control.
Wherein, train in operational process often through multiple website, circuit between every two websites is called a speed limit section, due to reasons such as landform, each speed limit section can comprise one or more speed restrictive block again, a speed limit section is comprised to the situation of a speed restrictive block, and the limited speed of easy understand in this speed limit section is identical, a speed limit section is comprised to the situation of multiple speed restrictive block, the limited speed of each speed restrictive block is not identical.Generally, speed restrictive block can be divided into upper arc, lower arc, upper rank shape, lower rank shape four kinds of Interval Type according to the difference of limited speed, and as shown in Figure 2, Fig. 2 is limit section provided by the invention classification diagram.
When train is from a website, rate of onset is 0, before this situation appears at launch train or start time of run between computer installation simultaneously, certainly, if controller starts time of run between computer installation in train travelling process, so rate of onset is just the current running velocity of train.
Wherein, train acceleration is a vector, when train accelerates, this train acceleration be on the occasion of, when train deceleration, this train acceleration is negative value.
Between the station of controller calculating train described above, time of run is generally will calculate once at interval of a period of time, should be understood that, suppose that the schedule time scope of whole speed limit section is 20 minutes to 22 minutes, if be 15 minutes in train operation to the time spent when half, this represents that train is too slow in the speed of the first half speed limit section, calculating train like this will be faster than the coasting speed of the later half speed limit section calculated before launch train in the coasting speed of later half speed limit section, because between guarantee station, time of run was within the scope of the schedule time like this.
In order to prevent train from exceeding the speed limit, the limited speed of each speed restrictive block is respectively the maximum speed of each speed restrictive block and the difference of speed safe clearance, and those skilled in the art can this speed safe clearance of sets itself as required.
Wherein, controller also obtains train coasting speed at each speed restrictive block with the initial value preset by dichotomy iterative computation for the limited speed according to each speed restrictive block.That is, coasting speed is calculated by dichotomy iteration, time of run according to the coasting speed calculated and between the station calculating train in conjunction with burst length, train acceleration, rate of onset, until time of run is within the scope of the schedule time and just stops iterative computation between the station calculated, and be in time of run between station the operation that coasting speed corresponding within the scope of the schedule time controls train according to calculated.Coasting speed is train at the non-acceleration of a speed restrictive block, the moving velocity in non-decelerating phase, such as, train accelerates from 0 at the moving velocity of a speed restrictive block, be finally 0 out of service with moving velocity, so this train accelerates until reach coasting speed from 0, when near terminal, be decelerated to 0 again, in this case, coasting speed is exactly the maximum speed of this speed restrictive block.
Below described above is described in detail by dichotomy iterative computation coasting speed.
Fig. 3 is run curve 20 schematic diagram of time of run between the shortest station provided by the invention, in figure 3, A B station of standing is a speed limit section 10, this speed limit section 10 comprises 5 speed restrictive blocks, be respectively the 1st speed restrictive block, the 2nd speed restrictive block, the 3rd speed restrictive block, the 4th speed restrictive block, the 5th speed restrictive block, identify with 1,2,3,4,5 respectively in figure 3.If wish to obtain time of run between the shortest station, its running velocity just should keep maximum, but, in order to ensure safety, limited speed V here
cx(x identifies the mark of speed restrictive block, such as, and V
c1represent the limited speed of the 1st speed restrictive block) and limited speed between should ensure a speed safe clearance △ V.In Fig. 3 and other embodiments of the invention, when train needs to carry out acceleration-deceleration, all with peak acceleration V
maxwith maximum deceleration V
mincarry out accelerating and slowing down.
If train runs with the run curve 20 of time of run between the shortest station shown in Fig. 3, so the time of run of train between standing in A station and B is also the shortest, i.e. time of run between the shortest station, but, if time of run is still greater than the upper limit of schedule time scope between this shortest station, so do not had between iterative space, train just runs with the run curve 20 of time of run between this shortest station.But, if between this shortest station, time of run was within the scope of the schedule time (be namely more than or equal to the lower limit of schedule time scope and be less than or equal to the upper limit of schedule time scope), also do not need to carry out iteration, train just runs with the run curve 20 of time of run between this shortest station.
But, if time of run is less than the lower limit of schedule time scope between this shortest station, so just need to carry out iterative computation to the coasting speed of train.Fig. 4 is run curve 30 schematic diagram between the station after first time provided by the invention iteration, in the first iteration, and maxim V

When speed limit section comprises multiple speed restrictive block, for the first adjacent speed restrictive block and the second speed restrictive block, the terminal velocity of the first speed restrictive block is the top speed of the second speed restrictive block, this terminal velocity or this top speed are not more than the limited speed of arbitrary speed restrictive block of this first adjacent speed restrictive block and the second speed restrictive block, so, can be found out by Fig. 3 to Fig. 6, if the limited speed of the first speed restrictive block is less than the limited speed of the second speed restrictive block, the accelerator that so train accelerates to the coasting speed of the second speed restrictive block from the coasting speed of the first speed restrictive block is carried out at the second speed restrictive block, but, if the limited speed of the first speed restrictive block is greater than the limited speed of the second speed restrictive block, so the moderating process of the coasting speed of train from the coasting speed reduction of the first speed restrictive block to the second speed restrictive block is carried out at the first speed restrictive block.
In train travelling process, iterative process described above will carry out once at interval of a time cycle, such as, just carried out an iterative computation at interval of 10 seconds.
4 kinds of situations below train run curve between the station driving to B station from A station exists:
(1) from A station startup, stop to B station, namely standing from A with initial velocity is 0 startup, is 0 to the speed during stopping of B station;
(2) from A station startup, do not stop to B station, namely standing from A with initial velocity is 0 startup, does not stop to B station, is not 0 in the speed at B station;
(3) stand from A with the speed being greater than 0, stop to B station, namely train is not 0 in the speed that A stands, and speed when stopping to B station is 0;
(4) stand from A with the speed being greater than 0, do not stop to B station, namely train is not 0 in the speed that A stands, and does not stop to B station, is not 0 in the speed at B station.
Between 4 kinds of stations described above, the computation process of running condition is similar, and difference is only the speed that train stand at A or the speed difference that train is stood at B.
