Embodiment two
In the present embodiment, it is still desirable to pre-establish the computation model of train driving curve, its specifically establish process with
It is identical in embodiment one, seldom repeat herein；
This embodiment offers a kind of offline and online handling process such as Fig. 3 institutes for combining adjustment and driving the method for curve
Show, including following processing step：
Step 21, will adjustment starting point between train terminal according to distance carry out interval division, make train in each section
Speed limit and the gradient keep it is identical；Wherein, train is determined according to the initial driving curve before train on-line operation data and adjustment
Adjust starting point；Recently a latest update is driven into curve as the initial driving song before the adjustment described in the present embodiment
Line.Specifically, in the present embodiment, section is divided according to the gradient and speed-limiting messages, as long as the gradient and speed limit have a change
, then need to be divided into a new section.As shown in Figure 2, in figure above horizontal line segment description speed limit each section,
Each section of the following horizontal line segment description gradient, dotted line draw for each section；The distance in each section is actually should
The maximum of hauling distance in section, it is following for adjusting using adjustment amount adjustment hauling distance in sections, it is the area adjusted
Between actual hauling distance.
The initial driving curve according to before train on-line operation data and adjustment determines train adjustment position starting point, wraps
Include：
According to the train real time position and real-time speed of train on-line operation data acquisition；
The offline speed of the current location indexed in the driving curve adjusted offline；
When deviation occurs for real-time speed and offline speed, deviation is occurred with the real-time speed and the offline speed
Position is that train adjusts starting point.
Step 22, time deviation to be adjusted is calculated based on the initial driving curve before adjustment；
Specifically, based on the reality that the starting point in each adjustment section in section is adjusted corresponding to the initial driving curve before adjustment
It is inclined that the real-time speed of the estimated speed of the end in Shi Sudu and adjustment section point and the end point in adjustment section calculates the time to be adjusted
Difference；
For each adjustment section because when deviation occurs for real-time speed and offline speed, with the real-time speed with
The position that deviation occurs for the offline speed adjusts starting point for train；The starting point of now train adjustment must be in a section
Point, setting train are as adjustment starting point, initial real-time speed from i-th point of the starting point in n-th sectionTrain is
The last point i+1 points in N number of section it is expected that speed beBut after there is deviation, last point of the train in n-th section
I+1 point real-time speeds are
So for n-th section,
It is as adjustment starting point, initial real-time speed from the starting point i+1 point in the N+1 sectionRow
Car n-th section last point i+2 points it is expected that speed beBut after there is deviation, train is in n-th section
Last point i+1 point real-time speeds be
For the N+1 section,
By that analogy, section M is adjusted to last one,
For time deviation Δ T=Δs T (N) to be adjusted+Δ T (N+1)+...+Δ T (N+M)；
Step 203, first adjustment section is chosen in the section；
In the selection in adjustment section, adjustment is required for saving to greatest extent each time in principle, in actual applications,
The selection in first adjustment section is different with the system of selection in non-first adjustment section；
During selection for first adjustment section, using the hauling distance and each area for calculating each section in the present embodiment
Between energy consumption ratio alternatively it is first adjustment section reference index；The reference index is used to that energy-saving effect can be reflected,
Therefore the maximum section of energy-saving effect is chosen as the section for first adjustment according to this reference index.
The maximum section of reference index is chosen in the section as first adjustment section；
After first adjustment interval selection；
Step 24, based on initial curve is driven, obtained according to the hauling distance first in the adjustment section and adjusted first
Driving curve；Hauling distance first using the hauling distance in the first adjustment section after adjustment as adjustment section, according to
The hauling distance first in adjustment section obtains the driving curve adjusted first；
Step 25, based on the driving curve adjusted first judge whether time deviation to be adjusted eliminates；
After adjusting first, setting train is used as adjustment starting point, initial real-time speed from i-th point of the starting point in n-th section
ForTrain n-th section last point i+1 points it is expected that speed beBut after there is deviation, train
Last point i+1 point real-time speeds in n-th section are
So for n-th section,
It is as adjustment starting point, initial real-time speed from the starting point i+1 point in the N+1 sectionRow
Car n-th section last point i+2 points it is expected that speed beBut after there is deviation, train is in n-th section
Last point i+1 point real-time speeds be
For the N+1 section,
By that analogy, section M is adjusted to last one,
ΔT1=Δ T1(N)+ΔT1(N+1)+…+ΔT1(N+M)；
Judge whether time deviation to be adjusted eliminates, that is, judge Δ T1Whether it is equal to 0, if equal to 0, proves to be adjusted
Time deviation eliminated, if not equal to 0, time deviation to be adjusted also needs to continue to adjust；Then repeat under execution
Step 23 is stated to step 25；
Step 23 is performed again, non-first adjustment section is chosen in the section；
During selection adjustment section, in addition to first adjustment section, selection makes this (for the second time) adjustment total energy consumption and upper one
The difference maximum section of secondary adjustment total energy consumption is as non-first adjustment section；Wherein, curve is driven based on this (for the second time) to obtain
This is taken to adjust total energy consumption；The difference of this (for the second time) adjustment total energy consumption and last adjustment total energy consumption changes for this energy consumption
Amount.
Now, to all sections in addition to first adjustment section, a pre-computation is carried out, it is assumed that to each section
For pre-adjustment section when, adjusted using default hauling distance adjustment amount and update the hauling distance in the pre-adjustment section；It is based on
The adjustment that the driving curve adjusted first can obtain each pre-adjustment section drives curve, respectively for each pre-adjustment section
All obtain this pre-adjustment total energy consumption Ei；(last time) adjusts driving curve acquisition based on (last time) first adjustment first
Adjustment total energy consumption E；Compare each pre-adjustment section and obtain this pre-adjustment total energy consumption EiWith (last time) first adjustment
Adjust total energy consumption E difference DELTA Ei,
ΔEi=Ei-E；I represents the numbering in each pre-adjustment section；In operation result Δ EiThe maximum Δ E of middle selection is corresponding
Pre-adjustment section as this adjustment section.
Step 24, the driving curve based on last (first) adjustment, according to the non-first adjustment section this (the
It is secondary) hauling distance obtain this (for the second time) adjustment driving curve；Using the adjustment of default hauling distance adjustment amount simultaneously
Update this hauling distance for adjusting section (for the second time)；In the present embodiment, with the traction before the adjustment of the adjustment section
The difference of distance and default hauling distance adjustment amount is as the hauling distance that section is adjusted this described.Wherein, it is default to lead
It is to be less than leading for each adjustment section according to an adjustment amount set by practical operation situation, the adjustment amount to draw apart from adjustment amount
Draw distance.
Step 25, judge whether this time total amount to be adjusted after adjusting eliminates；
After this (for the second time) adjustment, setting train is used as adjustment starting point from i-th point of the starting point in n-th section, initially
Real-time speed isTrain n-th section last point i+1 points it is expected that speed beBut occur inclined
After difference, last point i+1 point real-time speed of the train in n-th section is
So for n-th section,
It is as adjustment starting point, initial real-time speed from the starting point i+1 point in the N+1 sectionRow
Car n-th section last point i+2 points it is expected that speed beBut after there is deviation, train is in n-th section
Last point i+1 point real-time speeds be
For the N+1 section,
By that analogy, section M is adjusted to last one,
ΔT2=Δ T2(N)+ΔT2(N+1)+…+ΔT2(N+M)；
Judge whether time deviation to be adjusted eliminates, that is, judge Δ T2Whether it is equal to 0, if equal to 0, proves to be adjusted
Time deviation eliminated, then stop performing step 23 to step 25；
If not equal to 0, time deviation to be adjusted also needs to continue to adjust；Then repeat and perform step 23 to step
25。
