Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The train operation map processing method, apparatus, electronic device and storage medium of the present invention are described below with reference to fig. 1 to 7.
As shown in fig. 1, the train running chart processing method provided by the invention includes:
step 110, determining the total travel time of passengers based on the train running time, the train stop time, the train starting-to-stop time and the station stop attribute corresponding to the station interval.
It will be appreciated that the train operation time corresponding to the station interval, i.e. the operation time of the train between two stations. Station stop attribute, namely whether the train needs to jump at the corresponding station.
Further, the station stopping attribute is 0, namely the train does not jump to stop at the station; the stop attribute of the station is 1, namely, the train is to jump and stop at the station.
For example, the importance of a station may be evaluated based on station attributes of a station along the way, such as transportation hubs of a train station, a bus station, etc., business areas, large-sized residential areas, scenic spots, etc., given a larger weight attribute, and given a smaller weight attribute to a general station. Stations with greater weight attributes have longer train stops and stations with lesser weight attributes have shorter train stops.
Step 120, determining the total cost of train operation based on the train departure time interval, the train cost, and the total number of slow train departure.
It can be appreciated that the smaller the train departure time interval, the higher the train running cost it correspondingly generates; conversely, the larger the train departure time interval, the lower the train running costs it correspondingly generates.
The train cost comprises the fixed cost of the train and the cost of each stop of the train; the fixed cost of the train is the cost generated when the train runs on the corresponding line; the cost of each stop of the train can include the energy consumption cost in the train braking process and the personnel maintenance cost.
It should be noted that, the slow train refers to a train stopped at each station in a preset line, and the slow train corresponds to a large station fast train, that is, a train stopped at a critical large station.
Step 130, determining a stop position of the large station express train based on the total travel time of the passengers and the total running cost of the train.
It is understood that the total travel time of the passengers is determined to meet the requirements, and the total cost of running the train also meets the requirements, corresponding to the stop position of the large-station express train.
And 140, obtaining a train operation diagram based on the stop position of the large station express train.
It can be understood that based on the stop position of the large station express way, a corresponding large intersection operation diagram can be generated, further, based on the large intersection operation diagram, a corresponding small intersection operation diagram is generated, and finally, based on the large intersection operation diagram and the small intersection operation diagram, the train operation diagram can be obtained.
In some embodiments, the determining the total travel time of the passenger based on the train running time, the train stop time, the train start-to-stop time, and the station stop attribute corresponding to the station interval includes:
determining the total travel time of the passenger based on the following formula:
wherein Z is 1 Is the total travel time of the passengers, t ij Is the running time of the positive line section of the train from station i to station j and i not equal to j, N is the total number of stations of the target line,for stopping time of train at kth station,/-for the train at kth station>For the time from start to stop of the train in a single section d 1 For a fixed time, x, of train operation in all intervals of a target line k Station stopping attribute, x, of the kth station k ≥1。
It can be understood that the stop position of the large station express car is determined by comprehensively considering city planning according to the passenger flow volume of the subway station entering and exiting, the travel time of passengers and the operation cost of enterprises. The passenger's business turn over station condition can be through the input destination acquisition when entering the station, generally realizes through intelligent terminal.
Meanwhile, the importance of the stations is evaluated according to the station attributes of the stations along the way, such as transportation hubs of railway stations, bus stations and the like, business areas, large residential areas, scenic spots and the like are given larger weight, namely station stop attributes, and general stations are given smaller weight.
And establishing a model according to indexes such as passenger flow of a station, travel time of passengers, operation cost of an enterprise and the like, and acquiring the parking position of a large station express train through two objective functions.
In some embodiments, the determining the total cost of train operation based on the train departure time interval, the train cost, and the total number of slow train departure comprises:
determining the total cost of train operation based on the formula:
wherein Z is 2 For the total running cost of the train, deltaT is the train departure time interval, deltaT is more than 0, C 1 For fixing the cost of the train, C 2 For the cost of each stop of the train, m 1 For the total number of slow train departure, x k Is the stop attribute of the kth station.
It will be appreciated that the minimum of the two equations is obtained based on the constraints, thereby obtaining the location of the stop of the large station vehicle. The minimum value in the two formulas can reduce the travel time of passengers and reduce the running cost.
In some embodiments, the determining a large station express parking location based on the passenger total travel time, and the train operation total cost, comprises:
determining a minimum passenger total trip time and a minimum total cost of train operation;
and determining the stop position of the large station express train based on the minimum total travel time of the passengers and the minimum total cost of train operation.
In some embodiments, the obtaining a train operation chart based on the large station express parking position includes:
determining a large intersection based on the stop position of the large station express train, and setting a small intersection in the large intersection;
and obtaining the train operation diagram based on the large intersection and the small intersection.
It will be appreciated that the early peak period is the period of maximum dispatch command pressure and that if the passenger demand during the early peak period is met, the passenger demand during other periods throughout the day may be considered to be met as well. Therefore, the large crossing and the small crossing can be determined based on the passenger flow of the early peak period, and then the train running diagram can be determined.
And in a preset study period, trains in the large and small crossing all travel at the same time interval. The small intersections can be arranged in the middle or at two ends of the large intersections in a large intersection nesting mode.
The value of the driving interval of the small crossing needs to meet the requirement of the passenger flow of the small crossing, and in order to avoid the driving conflict of the train on the ascending or descending road, the driving interval of the large crossing train, namely the large station express train, needs to be integral multiple of the small crossing.
When the calculated small intersection is the traffic interval of the large intersection from the starting station to the terminal station, the value of the traffic interval of the small intersection is the same as that of the large intersection.
In some embodiments, the train working diagram processing method further comprises:
and under the condition that the first target train enters the terminal station of the minor intersection, the target carriage of the first target train is disassembled and then is linked to the second target train.
It will be appreciated that, in order to facilitate the turn-back of the minor intersection, the turn-back problem of the minor intersection starting station and the terminal station is considered in the initial stage of the line construction, as shown in fig. 2, a crossover line and a parking line are designed before or after the minor intersection starting station and the terminal station for the turn-back and parking of the minor intersection.
The section passenger flow refers to passenger flow passing through each section of a rail transit line, is generally counted in units of hours or whole days, and is divided into uplink section passenger flow and downlink section passenger flow according to the running direction of a train.
The design of the dynamic grouping of trains is as follows:
in order to facilitate passenger flow exchange between different small intersections, the small intersections can be disassembled in a dynamic grouping mode, and a terminal station of the small intersections is generally a station for the dynamic disassembly of the small intersections. And (3) coupling the uncoded carriage (namely, the target carriage of the first target train) of the terminal station of one small crossing to the small crossing carriage (namely, the second target train) of the other small crossing, wherein the uncoded carriage is used as an active coupling vehicle, and the other small crossing carriage is a passive coupling vehicle.
A schematic diagram of dynamic uncoupling and coupling of the train is shown in fig. 3. The first trolley in the figure (i.e., the first target train) can select a 4-consist, a 6-consist, an 8-consist, or a 10-consist, and the type of the consist is determined according to the traffic volume. After passing through the small road terminal station, the train automatically breaks 2 groups or 4 groups, and then the broken train is linked with a second small traffic car (namely a second target train) in the new small road to form a new small traffic car, so as to finish dynamic breaking and linking.
In other embodiments, the train operation diagram processing method provided by the invention is as follows:
(1) Selecting a stop point for a large station express car
B and C are respectively a railway station and a central business area with more congested passenger flows according to passenger flow analysis, and in order to relieve traffic congestion, B and C are used as the second stop points of the large-station express train, so that the obtained operation line schematic diagram of the large-station express train is obtained.
(2) Selecting a start point and an end point of a large and small intersection
If the station A, the station B and the station C are selected as the starting stations of the small intersection according to the boarding difficulty and waiting time of passengers, the intersection schematic diagram is shown in fig. 4.
If stations a, AB, B, and C are selected as the start stations for the minor intersections, the intersections are drawn as shown in fig. 5, depending on the difficulty of boarding and waiting time of the passengers.
(3) Dynamic uncoupling and coupling for selecting train
A schematic diagram of dynamic uncoupling and coupling of the train is shown in fig. 3. The first trolley in the figure (i.e., the first target train) can select a 4-consist, a 6-consist, an 8-consist, or a 10-consist, and the type of the consist is determined according to the traffic volume. After passing through the small road terminal station, the train automatically breaks 2 groups or 4 groups, and then the broken train is linked with a second small traffic car (namely a second target train) in the new small road to form a new small traffic car, so as to finish dynamic breaking and linking.
