In some embodiments, the electronic device obtaining a plurality of first online vehicles running in a target traffic direction may include: the electronic equipment acquires a plurality of third online vehicles running along a target running intersection direction and the corresponding quantity of all the third online vehicles; the electronic device determines a plurality of first online vehicles from a plurality of third online vehicles according to the number and the preset number of vehicles.
The preset number of vehicles is the number of vehicles required for a new running route and can be represented by n New pattern .
For example, after acquiring a plurality of initial online vehicles running along a target running route direction, the electronic device may first acquire respective current position data of the plurality of initial online vehicles, and determine, for the current position data of each initial online vehicle, whether the initial online vehicle can run to a terminal station of a new running route, where the terminal station may include a station S 1 or a station S n, a determination process is as follows:
If the initial on-line vehicle cannot be operated to the terminal of the new operation route, the electronic device arranges for the initial on-line vehicle to be taken off-line back to the vehicle section. At this time, for a plurality of initial online vehicles, the electronic device acquires a plurality of third online vehicles, which are other initial online vehicles capable of running to a new running intersection terminal except for the initial online vehicle of the return vehicle section. The electronic device then determines a corresponding number of all third online vehicles, which number may be represented by n Online line ; then, the electronic device determines a plurality of first online vehicles from the plurality of third online vehicles according to n Online line and n New pattern , so as to dynamically adjust the number of the first online vehicles corresponding to the non-target destination return rail.
If the initial online vehicle can run to the terminal of the new running intersection, the electronic device adjusts the terminal of the initial online vehicle to be the terminal in the same direction as the new running intersection according to the running direction of the initial online vehicle, the platform of the approach and the interval running time, and at this time, the adjusted terminal of the initial online vehicle is the terminal of the new running intersection (S 1 or S n).
The adjustment process of the terminal station is as follows: the electronic device changes the running intersection after the i-th initial online vehicle current position to a new running intersection, the corresponding arrival time may be denoted as a Si+1, Upper part =DSi, Upper part +ti,i+1, and the corresponding departure time may be denoted as D Si+1, Upper part =ASi+1, Upper part +ti+1, Stop and stop . At this time, for a plurality of initial online vehicles, the electronic device acquires a plurality of third online vehicles, where the plurality of third online vehicles are all initial online vehicles capable of running to the terminal station of the new running intersection, and then determines a plurality of first online vehicles from the plurality of third online vehicles in combination with n New pattern , so as to dynamically adjust the number of vehicles of the first online vehicles corresponding to the non-target destination return rail.
Wherein a Si+1, Upper part represents the arrival time of the i-th initial online vehicle at the station S i+1, Upper part , station S i+1, Upper part represents the upstream station corresponding to station S i+1, station S i, Upper part represents the upstream station corresponding to station S i, station S i represents the station where the i-th initial online vehicle is currently located, station S i+1 represents the next station of station S i, D Si, Upper part represents the departure time of the i-th initial online vehicle at station S i, Upper part , t i,i+1 represents the running time of the i-th initial online vehicle from station S i, Upper part to station S i+1, Upper part , D Si+1, Upper part represents the departure time of the i-th initial online vehicle at station S i+1, Upper part , and t i+1, Stop and stop represents the stop time of the i-th initial online vehicle at station S i+1, Upper part .
In some embodiments, the determining, by the electronic device, a plurality of first online vehicles from the plurality of third online vehicles according to the number and the preset number of vehicles may include: the method comprises the steps that under the condition that the number of the electronic devices is equal to the number of preset vehicles, a plurality of third online vehicles are determined to be a plurality of first online vehicles; the electronic equipment determines a first difference value between the number and the number of the preset vehicles under the condition that the number is larger than the number of the preset vehicles; off-line third online vehicles corresponding to the first difference value from the plurality of third online vehicles, and determining the remaining third online vehicles as a plurality of first online vehicles; the electronic equipment determines a second difference value between the number of the preset vehicles and the number of the preset vehicles under the condition that the number of the electronic equipment is smaller than the number of the preset vehicles; and acquiring an alternative vehicle corresponding to the second difference value, and determining the third online vehicle and the alternative vehicle as a plurality of first online vehicles.
After obtaining the number n Online line and the preset number n New pattern of vehicles, the electronic device may compare the number n Online line with the preset number n New pattern of vehicles to determine a plurality of first online vehicles from a plurality of third online vehicles. The specific process is as follows: in the case of n Online line =n New pattern , it is illustrated that a plurality of third online vehicles are sufficient to provide data support for a subsequent determination of the target vehicle operating map, at which point the electronic device does not need to schedule third online vehicles to come off line and/or alternative vehicles to come on line, and directly determines the plurality of third online vehicles as a plurality of first online vehicles.
In the case of n Online line >n New pattern , indicating that there are too many third online vehicles, at this time, the electronic device determines a first difference value between n Online line and n New pattern (i.e., n Online line -n New pattern ), and downloads a third online vehicle corresponding to the first difference value from the plurality of third online vehicles, and generally selects a third online vehicle offline vehicle segment corresponding to a first difference value closest to the vehicle segment from the plurality of third online vehicles; at this point, the remaining third online vehicles of the plurality of third online vehicles are sufficient to provide data support for a subsequent determination of the target vehicle operating map, which the electronic device may determine as the plurality of first online vehicles.
In the case of n Online line <n New pattern , indicating that the third online vehicles are fewer and insufficient to provide data support for the subsequent determination of the target vehicle running map, at this time, the electronic device determines a second difference value between n New pattern and n Online line (i.e., n New pattern -n Online line ), and brings the candidate vehicles corresponding to the second difference value in the vehicle segment into line, typically selecting a period with the largest interval time between the third online vehicles, and sequentially arranging the candidate vehicles into line; then, a plurality of third online vehicles and an alternative vehicle corresponding to the second difference are determined as a plurality of first online vehicles.
Exemplary, as shown in fig. 2, a schematic diagram of a vehicle running diagram of the on-line alternative vehicle provided by the invention is shown. As can be seen from fig. 2, the first on-line vehicles have a range run time of 9 to 10 points 50, and the stations of the approach are { S 1,…,S16 }; at point 9, 52, 1 candidate vehicle is brought up from the vehicle segment; in the vehicle running map, the interval time between the first in-line vehicles is uneven.

Illustratively, the first online vehicle set currently executing the upstream may be represented by i= { I 1,I2,I3,…,Ii,Ii+1,Ii+2,…,Ij }. If the destination return rail of each first online vehicle in the set { I 1,I2,I3,…,Ii } is the target destination return rail S n, Folding device , the electronic device does not need to dynamically adjust the number of vehicles. If the first online vehicle with the destination return rail being the non-target destination return rail S 1, Folding device exists in the set { I i+1,Ii+2,…,Ij }, the electronic device needs to dynamically adjust the number of vehicles of the first online vehicle, that is, add a new number of vehicles plan for the first online vehicle to run from the non-target destination return rail S 1, Folding device to the target destination return rail S n, Folding device , where the new number of vehicles plan corresponds to the adjusted first online vehicle I i+1, that is, the second online vehicle I' i+1.
The dynamic adjustment process of the train number is as follows: for the set { I i+1,Ii+2,…,Ij }, the electronic device determines the arrival time of the corresponding number of vehicles of the first online vehicle I i+1 at the downlink station S 1, Lower part(s) corresponding to the station S 1, which may be denoted by a S1, Lower part(s) ; the electronic device further determines a minimum turn-back time of the corresponding number of vehicles of the first online vehicle I i+1 at the station S 1, Lower part(s) , which may be denoted by t 1, Folding device ; next, the electronic device determines, according to a S1, Lower part(s) and t 1, Folding device , a departure time of the second online vehicle I' i+1 at the station S 1, Upper part corresponding to the number of vehicles, which may be represented by D S1, Upper part , where D S1, Upper part =AS1, Lower part(s) +t1, Folding device ; the electronic device adjusts the non-target end point turning rail S 1, Folding device corresponding to the first online vehicle I i+1 to be the target end point turning rail S n, Folding device according to the platform and the section running time of the first online vehicle I i+1 route, and the adjusted first online vehicle I i+1 is the second online vehicle I' i+1.
