Described according to train on-line operation data and adjustment before initial driving curve determine train adjustment position starting point, bag
Include：
Train real time position according to train on-line operation data acquisition and real-time speed；
The offline speed driving the current location of index in curve in offline adjustment；
When real-time speed and offline speed occur deviation, deviation is occurred with described offline speed with described real-time speed
Position adjusts starting point for train.
Step 22, time deviation to be adjusted is calculated based on the initial driving curve before adjustment；
Specifically, the reality based on the interval starting point of each adjustment in the corresponding adjustment of the initial driving curve before adjustment interval
It is inclined that the real-time speed of the end point in the estimated speed of end point in Shi Sudu and adjustment interval and adjustment interval calculates the time to be adjusted
Difference；
Interval for each adjustment because when there is deviation in real-time speed and offline speed, with described real-time speed with
Described offline speed occurs the position of deviation to adjust starting point for train；The starting point of now train adjustment must be interval rising
Point, as adjustment starting point, initial real-time speed is i-th point of starting point setting train from n-th intervalTrain is
The estimated speed of N number of interval last point i+1 point isBut after deviation, train is in the interval last point of n-th
I+1 point real-time speed is
It is so interval for n-th,
From the N+1 interval starting point i+1 point as adjustment starting point, initial real-time speed isTrain
In the estimated speed of the interval last point i+2 point of n-th it isBut after deviation, train is in n-th interval
Last point i+1 point real-time speed is
It is interval for the N+1,
By that analogy, to the interval M of last adjustment,
For time deviation Δ T=Δ T (N) to be adjusted+Δ T (N+1)+...+Δ T (N+M)；
Step 203, to choose first adjustment in described interval interval；
In the interval selection of adjustment, adjustment is required for energy-conservation to greatest extent each time in principle, in actual applications,
The interval selection of the first adjustment system of selection interval with non-first adjustment is different；
For during the interval selection of first adjustment, using each interval hauling distance of calculating and each area in the present embodiment
Between energy consumption the ratio alternatively interval reference index of first adjustment；Described reference index is used for reflect energy-saving effect,
Therefore the maximum interval of energy-saving effect is chosen as the interval for first adjustment according to this reference index.
Choose the maximum interval of reference index interval as first adjustment in described interval；
After first adjustment interval selection；
Step 24, drive curve based on initial, obtained according to the interval hauling distance first of described adjustment and adjust first
Driving curve；By hauling distance interval for the first adjustment after adjustment as the interval hauling distance first of adjustment, according to
The driving curve that the interval hauling distance acquisition first of adjustment adjusts first；
Step 25, based on adjust first drive curve judge whether time deviation to be adjusted eliminates；
After adjusting first, set train from i-th point of the interval starting point of n-th as adjustment starting point, initial real-time speed
ForTrain in the estimated speed of the interval last point i+1 point of n-th isAfter but deviation occurs, train
In the interval last point i+1 point real-time speed of n-th it is
It is so interval for n-th,
From the N+1 interval starting point i+1 point as adjustment starting point, initial real-time speed isRow
Car in the estimated speed of the interval last point i+2 point of n-th isBut after deviation, train is interval in n-th
Last point i+1 point real-time speed be
It is interval for the N+1,
By that analogy, to the interval M of last adjustment,
ΔT1=Δ T1(N)+ΔT1(N+1)+…+ΔT1(N+M)；
Judge whether time deviation to be adjusted eliminates, that is, judge Δ T1Whether being equal to 0, if being equal to 0, proving to be adjusted
Time deviation eliminated, if being not equal to 0, time deviation to be adjusted also need to continue adjustment；Then repeat under execution
State step 23 to step 25；
Again execution step 23, to choose non-first adjustment in described interval interval；
When selecting adjustment interval, in addition to first adjustment interval, select to make this (for the second time) adjustment total energy consumption and upper
The difference of secondary adjustment total energy consumption is maximum interval interval as non-first adjustment；Wherein, drive curve based on this (for the second time) to obtain
This is taken to adjust total energy consumption；This (for the second time) adjustment total energy consumption and the difference of last adjustment total energy consumption change for this energy consumption
Amount.
Now, to all intervals in addition to first adjustment interval, carry out a pre-computation, it is assumed that to each interval
During for pre-adjustment interval, adjust and update the interval hauling distance of this pre-adjustment using default hauling distance adjustment amount；It is based on
Adjust first drives the adjustment driving curve that curve can obtain each pre-adjustment interval, is respectively directed to each pre-adjustment interval
All obtain this pre-adjustment total energy consumption Ei；Based on the driving curve acquisition that (last) adjusts first (last) adjustment first
Adjustment total energy consumption E；Relatively each pre-adjustment is interval obtains this pre-adjustment total energy consumption Ei(last) adjusts with first
Difference DELTA E of adjustment total energy consumption Ei,
ΔEi=Ei-E；I represents the interval numbering of each pre-adjustment；In operation result Δ EiThe middle Δ E selecting maximum corresponds to
The interval adjustment as this of pre-adjustment interval.
Step 24, the driving curve being adjusted based on last (first), according to interval this of described non-first adjustment (the
Secondary) hauling distance obtain the driving curve that this (for the second time) adjusts；Adjusted simultaneously using default hauling distance adjustment amount
Update the interval hauling distance of this (for the second time) described adjustment；In the present embodiment, with the traction before the interval adjustment of described adjustment
The difference of distance and default hauling distance adjustment amount is as adjusting interval hauling distance this described.Wherein, default lead
Drawing apart from adjustment amount is according to an adjustment amount set by practical operation situation, and this adjustment amount is less than each interval leading of adjustment
Draw distance.
Step 25, judge this adjustment after time total amount to be adjusted whether eliminate；
After this (for the second time) adjustment, i-th point of starting point setting train from n-th interval is as adjustment starting point, initial
Real-time speed isTrain in the estimated speed of the interval last point i+1 point of n-th isBut occur partially
After difference, train in the interval last point i+1 point real-time speed of n-th is
It is so interval for n-th,
From the N+1 interval starting point i+1 point as adjustment starting point, initial real-time speed isTrain
In the estimated speed of the interval last point i+2 point of n-th it isBut after deviation, train is in n-th interval
Last point i+1 point real-time speed is
It is interval for the N+1,
By that analogy, to the interval M of last adjustment,
ΔT2=Δ T2(N)+ΔT2(N+1)+…+ΔT2(N+M)；
Judge whether time deviation to be adjusted eliminates, that is, judge Δ T2Whether being equal to 0, if being equal to 0, proving to be adjusted
Time deviation eliminated, then stop execution step 23 to step 25；
If being not equal to 0, time deviation to be adjusted also needs to continue adjustment；Then repeat execution step 23 to step
25.
