Description
Technical Field
The invention relates to a train automatic driving curve generation technology, in particular to a train automatic driving curve generation method based on target and passenger flow difference.
Background
The automatic driving curve is used for providing a target speed instruction for the on-line speed tracking control of the train automatic driving control system in the running process of the train, so that the train can finally realize the tracking of the target speed through continuous adjustment according to the line data and the target instruction speed.
The operation time period of the train can be generally divided into a peak time period, a flat time period and a low peak time period, and the control targets of the train have differences in different operation time periods: the method has the advantages that the transportation pressure is high in the peak period, the train is required to run at a high speed and at a standard point in the interval, the transportation pressure is relatively low in the peak-levelling period, the riding comfort of passengers can be properly considered at the moment, the transportation pressure is almost not generated in the low peak period, and the operation cost is generally reduced as a priority, so that when the train automatic driving curve is generated in the prior art, three train automatic driving curves are generally generated aiming at the three operation periods; there are problems in that:
in the prior art, when three automatic train driving curves are generated, the fixed weight of passengers is taken as a basis, the influence of the change of the weight of the passengers on the operation of the train is not considered, and the resistance of the weight of the passengers on the train is obviously not negligible, so that the automatic train driving curves obtained in the prior art have great difference from actual conditions, particularly, the passenger capacity of the train has randomness, and various passenger capacity conditions (such as no full load at a peak time period or full load at a low peak time period and other various conditions) exist at any operation time period;
Therefore, it is necessary to generate an automatic driving curve for a train according to different running periods and passenger flow differences.
Disclosure of Invention
A train automatic driving curve generation method based on target and passenger flow difference is characterized in that: the method for generating the train automatic driving curve comprises the following steps:
1) designing a plurality of predetermined operation times within an operation time adjustment range corresponding to the peak period; under a single preset operation time condition, taking the weight of the passengers as a variable, designing various weight conditions of the passengers; under the condition of single passenger weight, on the premise of meeting the preset running time according to train parameters and line parameters, taking accurate parking as a single target, and generating a corresponding automatic driving curve in advance in an off-line manner by adopting a single-target optimization algorithm; a plurality of automatic driving curves corresponding to the peak period are marked as a peak period curve set;
(the running time adjustment range can be understood as follows: for example, in the peak time period, the reference running time between two stations is 150 seconds, in the actual running, the actual running time of the train is allowed to make certain positive and negative adjustments on the basis of the reference running time, such as positive and negative 10 seconds, so that the corresponding running time adjustment range is 140-160 seconds; when the preset running time is set, the step length can be 2 seconds, so that 11 preset running times of 140, 142, 144, 146, 148, 150 and 152 … … 160 can be obtained, and if the step length is changed, other kinds of preset running times can also be obtained);
Designing various preset operation times within the operation time adjusting range corresponding to the peak flattening time period; under a single preset operation time condition, taking the weight of the passengers as a variable, designing various weight conditions of the passengers; under the condition of single passenger weight, according to train parameters and line parameters, on the premise of meeting preset running time, taking minimum energy consumption, optimal comfort level and accurate parking as three targets, and adopting a multi-target optimization algorithm to generate a corresponding automatic driving curve in an off-line mode in advance; recording a plurality of automatic driving curves corresponding to the peak leveling period as a peak leveling period curve set;
designing various preset operation times within the operation time adjusting range corresponding to the low peak time period; under a single preset operation time condition, taking the weight of the passenger as a variable, designing various weight conditions of the passenger; under the condition of single passenger weight, according to train parameters and line parameters, on the premise of meeting preset running time, the minimum energy consumption and the accurate parking are taken as two targets (in a low-peak period, the train running speed is relatively low, the riding comfort is good, and therefore the comfort is not needed to be taken as the target), and a multi-objective optimization algorithm is adopted to generate a corresponding automatic driving curve in an off-line mode in advance; marking a plurality of automatic driving curves corresponding to the low peak time period as a low peak time period curve set;
The high peak section curve set, the flat peak section curve set and the low peak section curve set are pre-loaded into an automatic train driving control system;
recording the preset operation time and the weight of the passenger corresponding to the single automatic driving curve as a time parameter and a weight parameter respectively;
2) in a carriage of a train, in the running process of the train, when a train door is closed, an automatic train driving control system acquires an image in the carriage through an in-train camera device, processes the image to obtain the number of passengers, and then calculates the current weight of the passengers according to the number of the passengers; meanwhile, a dispatching room issues a target running time to the train automatic driving control system;
3) after the target running time and the current weight of the passenger are obtained, the automatic train driving control system automatically identifies which one of the peak time period, the flat time period and the low time period is the current time period according to the current time, then matches the target running time and the current weight of the passenger with the time parameter and the weight parameter concentrated by the corresponding curves, finds out the corresponding automatic driving curves, and then controls the train to run according to the found automatic driving curves; the curve set is one of a peak section curve set, a flat section curve set and a low section curve set.
The principle of the invention is as follows: when the automatic driving curve is generated, the automatic driving control target difference of the train at different time intervals is considered, the target function covers a single target, a double target and three targets, and meanwhile, the weight difference of passengers is also considered, so that the obtained automatic driving curve is more in line with the actual situation; moreover, the invention also designs various preset operation time conditions aiming at the operation time adjustment ranges of different time periods, and when in actual scheduling, a dispatcher can set specific target operation time in the operation time adjustment range, so that the automatic train driving control system can quickly find a corresponding automatic driving curve, thereby greatly improving the scheduling flexibility and being beneficial to the macroscopic scheduling of train operation;
certainly, due to more situations, if the automatic driving curve is generated on line, timeliness is difficult to guarantee, so that the automatic driving curve can be generated in advance only by adopting a mode of generating the automatic driving curve in advance in an off-line mode, but the automatic driving curve generation method has certain advantages that the mode of generating the automatic driving curve in advance in an off-line mode is not limited by effectiveness, and the preset operation time condition and the passenger weight change condition can be divided as finely as possible, so that the refinement degree of automatic driving control of the train is improved;
In specific implementation, the existing single-target and multi-target optimization algorithms can be used for generating the automatic driving curve, such as evolutionary computation (genetic algorithm, cultural algorithm, differential evolutionary algorithm, Memetic algorithm and the like), biological computation (artificial immune algorithm, clonal selection algorithm and DNA computation) and cluster intelligent computation (particle swarm algorithm, ant swarm algorithm, artificial bee colony and artificial fish colony algorithm); based on the prior art, it is known that obtaining information about the number of people in an image through an image is a well-established technology, and therefore, the image processing technology is only a "tool" for obtaining the number of people in the present invention, and in the specific implementation, a person skilled in the art can select a preferred method from the existing image processing technology.
The beneficial technical effects of the invention are as follows: the scheme considers the control target difference and the passenger weight difference at the same time, so that the automatic driving curve is more consistent with the actual situation.
