Detailed Description

Embodiments of the present invention will be described in detail below, by way of example with reference to the accompanying drawings.

Methods, apparatuses, trains, and storage media for adjusting the running time of a train section according to embodiments of the present invention are described below with reference to fig. 1 to 6. As shown in fig. 1, a method for adjusting the running time of a train section comprises the following steps:

Step S1: and determining a first mapping relation curve corresponding to the running distance between stations and the first residual running time, and a second mapping relation curve corresponding to the running distance between stations and the first target running speed.

Specifically, when a train is running between two stations (a departure station and a pickup station), the inter-station running distance is the distance between the current running position of the train and the departure station, the first remaining running time is the time required for the train to run from the current running position to the pickup station at the maximum speed, and the first target running speed is the target running speed corresponding to the train at the current running position. Therefore, the first mapping relation curve is used for representing the time required for the train to reach the train receiving station from the current running position at the maximum speed when the train is at different running positions, and the second mapping relation curve is used for representing the target running speed corresponding to the train at different running positions.

In a specific embodiment, the first mapping relationship and the second mapping relationship may be determined by pre-configured inter-station operation data. The inter-station operating data includes, but is not limited to, station information, inter-station operating distance data, first target operating speeds corresponding to different inter-station operating distances, operating time between adjacent two inter-station operating distances, reference acceleration and reference deceleration data of the train. Specifically, the relation between the inter-station running distance between two stations and the first target running speed can be calculated according to the reference acceleration and the reference deceleration, sampling points are selected, the target running speed corresponding to each sampling point is recorded as V_max, the running time interval between two adjacent sampling points can be calculated, and the relation between the inter-station running distance between two stations and the first residual running time can be determined according to the running time interval between two adjacent sampling points. Exemplary, configured inter-station operational data is shown in table 1.

TABLE 1

Step S2: when the inter-station operation time issued by the automatic train monitoring system is received, determining second residual operation time corresponding to different inter-station operation distances and second target operation speed corresponding to different inter-station operation distances according to the inter-station operation time, the first mapping relation curve and the second mapping relation curve.

Specifically, after determining a first mapping relation curve corresponding to the running distance between stations and the first remaining running time, the minimum running time and the maximum running time of the train can be determined by the first mapping relation curve so as to determine the running time range of the train between two stations. The minimum operation time is the corresponding first residual operation time when the inter-station operation distance is zero in the first mapping relation curve; the maximum running time is N times of the minimum running time, and N can be preset according to actual conditions and stored in the vehicle-mounted controller. For example, the minimum running time is recorded as T0, N is recorded as 1.5, and the maximum running time is 1.5T0, and the running time range of the train between two stations is (T0, 1.5T0), and the automatic train monitoring system issues running time between stations according to the running time range, so that the vehicle-mounted controller automatically controls the running of the train according to the running time between stations issued by the automatic train monitoring system.

In a specific embodiment, after determining the minimum running time and the maximum running time according to the first mapping relation curve, the vehicle-mounted controller feeds back the minimum running time and the maximum running time to the automatic train monitoring system, and the automatic train monitoring system issues inter-station running time within the running time range fed back by the vehicle-mounted controller according to requirements. The inter-station operation time issued by the automatic train monitoring system is 1.2T0, so that the vehicle-mounted controller determines a second remaining operation time corresponding to different inter-station operation distances and a second target operation speed corresponding to different inter-station operation distances according to the inter-station operation time, the first mapping relation curve and the second mapping relation curve, so as to control the operation of the train according to the second remaining operation time and the second target operation speed corresponding to different inter-station operation distances, namely, the operation of the train is automatically controlled according to the inter-station operation time issued by the automatic train monitoring system.

Step S3: and in the interval driving process, determining a third target operation speed corresponding to the operation distance between different stations according to the operation time between stations, the driving time of the train, the second residual operation time and the second target operation speed.

Specifically, in the process of inter-station driving, a late phenomenon of a train may occur due to changes of driving environments, such as curves, bridges and tunnels, in a driving route, that is, the total driving time of the train between two stations fluctuates relative to the inter-station operation time. It is understood that the travel time of a train is the time interval between the departure of the train from the departure station to the actual operating location.

Step S4: and controlling the running of the train according to the third target running speed corresponding to the running distances between different stations so as to adjust the interval running time of the train.

Specifically, the third target running speeds corresponding to running distances between different stations are calculated in real time, and the actual running speed of the train is controlled according to the third target running speeds, so that the interval running time of the train can be adjusted in real time, and the train can reach the receiving station according to the inter-station running time standard point issued by the automatic train monitoring system under the condition that the stop time of the train at the station is not required to be controlled, so that the interval running time of the train is accurately adjusted.

In one embodiment of the present invention, determining a second remaining operation time corresponding to an operation distance between different stations and a second target operation speed corresponding to an operation distance between different stations according to an inter-station operation time, a first mapping relationship curve, and a second mapping relationship curve includes: determining a first maximum remaining operation time according to the first mapping relation curve; calculating the ratio between the inter-station operation time and the first maximum remaining operation time; taking the product of the first residual operation time corresponding to the operation distance between different stations and the ratio value in the first mapping relation curve as the second residual operation time corresponding to the operation distance between different stations; and taking the product of the first target running speed corresponding to the running distance between different stations and the reciprocal of the ratio in the second mapping relation curve as a second target running speed corresponding to the running distance between different stations.

In a specific embodiment, as shown in fig. 2, the first mapping relationship is denoted as S-T-0, the first maximum remaining operation time is denoted as T0 for example, the time required for the corresponding train to reach the receiving station when the inter-station operation distance of the train is 0, the inter-station operation time is denoted as T0 for example, and the ratio between the inter-station operation time and the first maximum remaining operation time is denoted as m for example, where m=t0/T0. And taking the product of the first residual operation time corresponding to the operation distances between different stations and m in the first mapping relation curve S-T-0 as the second residual operation time corresponding to the operation distances between different stations, namely expanding the first residual operation time corresponding to the operation distances between different stations in the first mapping relation curve S-T-0 by m times in a same way, and obtaining the second residual operation time, wherein the second residual operation time is shown as a curve S-T-1. And the ratio between the first target running speeds V_max and m is used as the second target running speed corresponding to the running distance between different stations.

It will be appreciated that the ratio between the inter-station operating time and the first maximum remaining operating time is between 1-N to define the inter-station operating time of the train not to be excessive, affecting the passenger experience. After the inter-station operation time issued by the automatic train monitoring system is received, the second residual operation time and the second target operation speed are obtained by correspondingly expanding and shrinking the first residual operation time and the first target operation speed by m times so as to adapt to the adjustment required to be made by the train in actual operation, and better riding experience is brought to passengers.

In one embodiment of the present invention, determining a third target operating speed corresponding to different inter-station operating distances according to the inter-station operating time, the running time of the train, the second remaining operating time, and the second target operating speed includes:

wherein V3 is the third target operating speed, t1_ref is the second remaining operating time, T ₁ is the inter-station operating time, t_real is the running time of the train, and V2 is the second target operating speed.

In a specific embodiment, as shown in FIG. 2, when the train is traveling to the position s1, the second remaining traveling time t1_ref is the predicted remaining time, and T ₁ -t_real is the actual remaining time. In order to ensure that the train arrives at the receiving station at about the inter-station operation time T ₁, the ratio of the predicted remaining time to the actual remaining time is used as an adjusting factor to adjust the second target operation speed in real time, so that the actual operation speed of the train fluctuates near the second target operation speed, and the train can arrive at the receiving station on time after the inter-station operation time.

In one embodiment of the present invention, after controlling the operation of the train according to the third target operation speed corresponding to the operation distance between the different stations, the method further comprises: and sending out standard point and late point information according to the running time, the first residual running time and the inter-station running time of the train. Specifically, the method for sending out the quasi-point and late-point information according to the running time, the first remaining running time and the inter-station running time of the train comprises the following steps: when the sum of the running time and the first residual running time of the train is not more than the inter-station running time, quasi-point information is sent out; and when the sum of the running time and the first residual running time of the train is greater than the inter-station running time, sending out the late information.

Specifically, in the interval driving process, the embodiment of the invention sends out standard point and late point information according to the driving time, the first residual operation time and the inter-station operation time of the train. Specifically, when the sum of the running time and the first residual running time of the train is not more than the inter-station running time, the train is considered to be capable of reaching the receiving station in the inter-station running time, and the punctual information is sent out; when the sum of the running time and the first residual running time of the train is larger than the inter-station operation time, the train is considered to be unable to arrive at the receiving station within the inter-station operation time, and the late information is sent.

In one embodiment of the present invention, the late information includes a late time, and determining the late time includes: calculating a sum between the travel time of the train and the first remaining travel time; and taking the difference value between the sum value and the inter-station operation time as the late time.

Specifically, the sum of the running time of the train and the first remaining running time is the predicted running time of the train between the two stations, and the difference between the sum and the inter-station running time is the error between the predicted arrival time and the actual arrival time of the train, and therefore, the difference between the sum and the inter-station running time is taken as the late time.

In one embodiment of the present invention, determining a first mapping relationship curve corresponding to an inter-station operation distance-first remaining operation time and a second mapping relationship curve corresponding to an inter-station operation distance-first target operation speed includes: acquiring configured inter-station operation data; judging whether temporary speed limiting information between stations is received or not; when the temporary speed limiting information between stations is received, determining a first mapping relation curve and a second mapping relation curve according to the temporary speed limiting information between stations and configured operation data between stations; and when the temporary speed limiting information between the stations is not received, determining a first mapping relation curve and a second mapping relation curve according to the configured operation data between the stations.

Specifically, the inter-station operation data includes, but is not limited to, station information, inter-station operation distance data, first target operation speeds corresponding to different inter-station operation distances, operation time between adjacent two inter-station operation distances, reference acceleration and reference deceleration data of a train. The temporary speed limit information includes, but is not limited to, a start position and an end position of a temporary speed limit section between stations, and a highest traveling speed of the speed limit section.

In a specific embodiment, because of special conditions of a civil structure of a train track or other civil facilities, speed limitation needs to be performed on the train to ensure safety of the train, after configured inter-station operation data are acquired, whether temporary speed limitation information between stations is received needs to be judged, so that speed of the train in a speed limitation section is limited according to the temporary speed limitation information, and driving safety is ensured. Specifically, when the temporary speed limiting information is received, determining a first mapping relation curve and a second mapping relation curve corresponding to the inter-station operation distance-first residual operation time according to the inter-station temporary speed limiting information and the configured inter-station operation data; when the temporary speed limiting information between the stations is not received, the first mapping relation curve and the second mapping relation curve are determined only according to the configured operation data between the stations. Therefore, when the temporary speed limiting information is received, the running speed of the train can be automatically adjusted according to the inter-station running time issued by the automatic train monitoring system, so that the aim of accurate point arrival is fulfilled.

In one embodiment of the present invention, the configured inter-station operation data includes a fourth target operation speed corresponding to a preset inter-station operation distance, and a first operation time interval between two adjacent preset inter-station operation distances, and determining a first mapping relationship curve and a second mapping relationship curve according to the configured inter-station operation data includes: determining a third residual operation time corresponding to the operation distance between the preset stations according to a first operation time interval between the operation distances between two adjacent preset stations; and determining a first mapping relation curve and a second mapping relation curve according to the third residual operation time corresponding to the preset inter-station operation distance and the fourth target operation speed corresponding to the preset inter-station operation distance.

Specifically, as shown in table 1, the configured inter-station operation data is configured for easy understanding, a sampling point is set every 1 meter from a departure station, so that a third remaining operation time corresponding to a preset inter-station operation distance is determined according to a first operation time interval (i.e., an operation time interval in table 1) between two adjacent preset inter-station operation distances, the first operation time intervals corresponding to all preset inter-station operation distances are added and summed, i.e., a train interval operation time, and thus, a difference is made between the train interval operation time and a traveling time corresponding to each preset inter-station operation distance, and the third remaining operation time corresponding to each preset inter-station operation distance can be obtained; thus, the first mapping relation curve and the second mapping relation curve are determined according to the third remaining operation time corresponding to the preset inter-station operation distance and the fourth target operation speed corresponding to the preset inter-station operation distance (i.e., the target operation speed in table 1). It can be understood that the first mapping relationship curve is determined according to the third remaining operation time corresponding to the preset inter-station operation distance, and the second mapping relationship curve is determined according to the fourth target operation speed corresponding to the preset inter-station operation distance, which are obtained by curve fitting, and are not described herein. Illustratively, the first map is shown in FIG. 3 and the second map is shown as curve one in FIG. 4.

In one embodiment of the present invention, the inter-station temporary speed limit information includes a temporary speed limit section and a temporary speed limit speed, and determining a first mapping relation curve and a second mapping relation curve according to the inter-station temporary speed limit information and configured inter-station operation data includes: determining a fifth target running speed corresponding to the running distance between the preset stations under the condition of temporary speed limiting according to the temporary speed limiting section, the temporary speed limiting speed, the preset acceleration and the preset maximum allowable speed; taking the minimum value of the fifth target running speed and the fourth target running speed as a sixth target running speed corresponding to the running distance between preset stations; and determining a first mapping relation curve and a second mapping relation curve according to a sixth target running speed corresponding to the running distance between the preset stations.

Specifically, as shown in a curve II in FIG. 4, the inter-station running distance of the temporary speed limit section of the train is about 800-1000 m, the temporary speed limit speed is 40km/h, and in the case of temporary speed limit, the fifth target running speed corresponding to the preset inter-station running distance is shown in a curve II in FIG. 4.
