In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
Fig. 1 is a schematic flow chart of a dynamic scheduling method for a vehicle in rail transit according to an embodiment of the disclosure. Referring to fig. 1, the dynamic scheduling method (hereinafter, may be simply referred to as a "dynamic scheduling method" or "method") of a vehicle of the rail transit includes:
S11, acquiring passenger flow information of a first line in a first preset time period.
The first preset time period is a future time of the current time. The step obtains passenger flow information of a first line at a future time of the current time, and prepares for matching passenger flow and transport capacity. It is understood that the first line may be any line of rail traffic, as the disclosed embodiments are not limited in this respect.
In one embodiment, this step may include, but is not limited to:
Predicting passenger flow information of a first line in a first preset time period according to historical data; for example, the passenger flow information at the same time point today can be predicted from the passenger flow information at the current time point in yesterday or in the past several days.
Or acquiring passenger flow information of a first line in a first preset time period according to the two-dimensional code set by the station; for example, on the premise that the passenger scans the two-dimension code to enter the station, the information of the scanned two-dimension code can reflect the passenger flow information of the passenger.
Or acquiring the passenger flow information of the first line in the first preset time period according to the ticketing information. The ticket information can also reflect the passenger flow information of future time. Thus, the implementation manner of S11 is flexible and various, and may be flexibly set according to the requirement of the dynamic scheduling method, which is not limited by the embodiments of the present disclosure.
In other implementations, S11 may also be implemented in other manners, which are not limited by the embodiments of the present disclosure.
In other embodiments, the passenger flow information may be determined by combining two or more of the above methods, so that the passenger flow information is accurate, and accurate matching of subsequent passenger flows and transport capacities is facilitated.
S12, acquiring the residual capacity of the vehicle on the first line reaching the station in the first preset time period.
Wherein the vehicle comprises at least one vehicle unit, the remaining capacity being determined in dependence on a maximum load carrying capacity and a loaded capacity of the vehicle, the remaining capacity being indicative of a loadable capacity of the vehicle in a first predetermined period of time.
For example, a vehicle may be grouped from at least one vehicle unit, with at least one vehicle unit of the same vehicle being grouped in the same manner, and different vehicles being grouped in different manners. The vehicle unit may be one compartment, two compartments, or more compartments, to which the disclosed embodiments are not limited.
For example, the remaining capacity may be the difference between the maximum load capacity and the loaded capacity of the vehicle.
In one embodiment, this step may include, but is not limited to:
Acquiring passenger information in the vehicle through a camera, and acquiring the residual capacity of the vehicle on a first line arriving at a station in a first preset time period; by way of example, the number of passengers and the distribution of passengers in the vehicle can be determined by means of the information of passengers in the vehicle collected by the camera, so that the number of passengers which can also be carried by the vehicle, i.e. the remaining transport capacity of the vehicle, can be determined.
Or obtaining the remaining capacity of the vehicle of the first line to the station in the first preset time period by weighing; for example, the weight that the vehicle may also carry, i.e. the remaining capacity of the vehicle, may be determined from the current weight value of the vehicle and the full weight value of the vehicle.
In other embodiments, the remaining capacity of the vehicle may also be determined by other means known to those skilled in the art, as the disclosed embodiments are not limited in this regard.
In other embodiments, the remaining capacity of the vehicle may be determined by combining two or more of the above methods, so that the information of the remaining capacity is accurate, and accurate matching of the subsequent passenger flow and the capacity is facilitated.
S13, determining the number of the increased or decreased vehicle units according to the passenger flow information and the residual capacity.
Wherein, when the passenger flow is more and the residual capacity is insufficient, the number of vehicle units can be increased; or when the passenger flow is less and the residual capacity is more, the number of vehicle units can be reduced, so that the accurate matching of the passenger flow and the capacity can be realized.
S14, acquiring a target vehicle from vehicles on a first line reaching the station in a first preset time period, and increasing or decreasing the number of vehicle units corresponding to the number of the vehicle units for the target vehicle.
Wherein there may be more than one vehicle on the first route to the station within the first preset time period, the step may determine one or more of the vehicles as the target vehicle based on the selection policy and add or subtract a corresponding number of vehicle units thereto.
For example, when it is necessary to add vehicle units, one vehicle including the least vehicle units may be selected as the target vehicle, or a plurality of vehicles having a smaller number of vehicle units may be selected as the target vehicle; when it is necessary to reduce the vehicle units, the vehicle with the largest remaining capacity may be selected as the target vehicle, or several vehicles with more remaining capacities may be selected as the target vehicles.
In other implementations, the vehicle units may also be increased or decreased based on other selection strategies, which the disclosed embodiments do not limit.
It should be noted that, in fig. 1, the execution sequence of S11 and S12 may be interchanged or executed synchronously, which is not limited by the embodiment of the present disclosure.
According to the dynamic scheduling method provided by the embodiment of the disclosure, passenger flow information of a first line in a first preset time period is obtained, wherein the first preset time period is the future time of the current time; acquiring the residual capacity of the vehicle of the first line arriving at the station in a first preset time period, wherein the residual capacity is determined according to the maximum bearing capacity and the bearing capacity of the vehicle, and the vehicle comprises at least one vehicle unit; determining the number of increased or decreased vehicle units based on the passenger flow information and the remaining capacity; and acquiring a target vehicle from vehicles on a first line which arrives at the station in a first preset time period, and increasing or decreasing the number of vehicle units corresponding to the number of the vehicle units for the target vehicle. Therefore, the passenger flow volume can be matched with the actual transport capacity of the vehicle, thereby being beneficial to improving the utilization rate of the vehicle and improving the energy consumption problem caused by excessive residual transport capacity.
In an embodiment, fig. 2 is a schematic flow chart of another method for dynamically scheduling vehicles in rail transit according to an embodiment of the present disclosure, and fig. 2 is a possible implementation manner of S13 based on the embodiment shown in fig. 1: comprising the following steps:
s131, if the passenger flow information is larger than the residual capacity, determining to increase the first number of vehicle units.
If the passenger flow information is greater than the remaining capacity, the remaining capacity of the vehicle in the first preset time period of the route is insufficient to carry the passenger flow of the route in the first preset time period, and at this time, a vehicle unit needs to be added, so that the capacity of the vehicle is accurately matched with the passenger flow after the passenger flow information is added.
In one embodiment, this step may include the steps of:
Step one: and if the passenger flow information is larger than the residual capacity, determining the demand information according to the passenger flow information and the residual capacity.
Wherein the demand information corresponds to passenger flow information exceeding the remaining capacity. For example, the demand information may be determined by calculating a difference between the two.
Step two: the first number is determined based on the demand information and the load capacity of the vehicle units.
The demand information is divided by the bearing capacity of the vehicle unit, and the first quantity is obtained by rounding up.
Based on this, S14 in fig. 1 may include the steps of:
Step one: the target vehicle is determined according to the number of vehicle units and the first number of vehicles of the first line to the station in the first preset time period.
For example, a vehicle with a smaller number of vehicle units may be determined as the target vehicle, or two or more vehicles with a smaller number of vehicle units may be determined as the target vehicle, by comparing the number of vehicle units of each vehicle at the present time.
Step two: and acquiring a first number of vehicle units from the vehicle units to be grouped, adding the first number of vehicle units to the target vehicle, and after adding, matching the grouping of the first number of vehicle units with the target vehicle.
The vehicle units to be grouped can be stored in a parking lot beside the station, and when the vehicle units need to be added, a first number of vehicle units can be called out from the parking lot and added to a target vehicle; and, the increased first number of vehicle units is grouped in accordance with the target vehicle, thus achieving dynamic vehicle grouping control.
And S132, if the passenger flow information is smaller than the residual capacity, determining to reduce the second number of vehicle units.
If the passenger flow information is smaller than the remaining capacity, it indicates that the remaining capacity of the vehicle of the line in the first preset time period is enough to carry the passenger flow of the line in the first preset time period, and there is a margin, that is, there may still be no load of the vehicle unit, at this time, the vehicle unit needs to be reduced, so that after the reduction, the capacity of the vehicle is exactly matched with the passenger flow.
In one embodiment, this step may include:
step one: and if the passenger flow information is smaller than the residual capacity, determining the surplus according to the difference value of the residual capacity and the passenger flow information.
Wherein the surplus corresponds to the surplus capacity exceeding the passenger flow information. For example, the margin of the rich can be determined by calculating the difference between the two.
Step two: the second number is determined based on the margin and the load capacity of the vehicle unit.
And dividing the surplus by the bearing capacity of the vehicle unit, and rounding up to obtain a second number.
Based on this, S14 in fig. 1 may include the steps of:
step one: the target vehicle is determined according to the number of vehicle units and the second number of vehicles of the first line to the station in the first preset time period.
For example, by comparing the number of vehicle units of each vehicle at the current time, it may be determined that one or several vehicles with a larger number of vehicle units are the target vehicles; or by comparing the surplus of the vehicles, one or more vehicles with more surplus of the vehicles are determined as target vehicles.
Step two: and reducing a second number of vehicle units from the target vehicle, and ungrouping the second number of vehicle units.
The vehicle units which are subjected to the ungrouping can be stored in a parking lot beside the station and used as vehicles to be grouped again, so that the dynamic grouping and ungrouping control of the vehicles is realized.
In an embodiment, the method may further comprise: and sending adjustment instruction information to the target vehicle, wherein the adjustment instruction information is used for instructing that the vehicle units are increased or decreased for the target vehicle.
For example, the adjustment indication information may be sent to a dispatcher of the target vehicle to alert the dispatcher of the state of the vehicle within the first preset time period, so that the dispatcher can adjust the operation parameters of the vehicle. Alternatively, an adjustment prompt may be sent to the passenger to prompt the passenger to move to a vehicle unit, or to disperse to additional vehicle units.
The dynamic scheduling method provided by the embodiment of the disclosure can realize dynamic grouping control of vehicles (such as 'trains') based on a cluster group control technology, so that accurate matching of passenger flow and transport capacity can be realized. Specifically, the method first breaks up a conventional fixed-consist train into 1,2 or more grouped vehicle units (also referred to as "minimum train units") on which a fully functional train operation control device can be mounted; the ground train operation control system adopts a cluster group control technology, dynamically groups the minimum train units according to the dynamic change of the passenger flow of the line network and the distributed storage positions of the minimum train units of the line, and controls the minimum train units to input or withdraw from the train groups of the line operation service, thereby realizing the accurate matching of the transport capacity and the passenger flow, and simultaneously realizing the accurate control of the passenger flow and the energy consumption.
Based on the same inventive concept, the disclosure also provides a dynamic scheduling device of a vehicle of rail transit, which can be used for executing the dynamic scheduling method of any one of the rail transit vehicles provided by the embodiment. Therefore, the device also has the technical effects of the dynamic scheduling method of the rail transit vehicle in any of the above embodiments, and the same points can be understood with reference to the explanation of the method above, and will not be described in detail.

If the passenger flow information is smaller than the residual capacity, the residual capacity of the vehicle in the first preset time period of the line is enough to bear the passenger flow of the line in the first preset time period, and the vehicle unit is still likely to be empty when the surplus capacity exists, and at the moment, the vehicle unit needs to be reduced so that the capacity of the vehicle is accurately matched with the passenger flow after the vehicle is reduced, and meanwhile, the energy consumption is reduced.
