Description

Technical Field

[0001] The present application relates to the field of rail transportation, and in particular to a method and system for dividing high-speed maglev operation and control zones. Background Art

[0002] During the construction and operation of high-speed maglev lines, the division of maglev line operation and control zones is crucial for tasks such as train control, safety protection, automatic operation, and management and scheduling. Numerous studies have yielded numerous results on the division of maglev line operation and control zones. One approach employs a global distribution optimization model to divide block zones, devising two division methods corresponding to the optimization objectives of maximizing train throughput efficiency and minimizing economic costs. Another approach establishes a 0-1 planning model for optimizing power supply zone division, with the objective function of minimizing the number of power supply zones. This model can solve the power supply zone division problem under the influence of line speed limits and slopes, reducing the number of power supply zones and saving construction and operating costs.

Furthermore, the construction of high-speed maglev lines requires consideration of the relationship between operation and control zones and power supply zones. Typically, the length of the operation and control zones is determined as an integer multiple of the power supply zone length.

[0045] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.

[0046] Example 1

[0047] like Figure 1 As shown, this embodiment proposes a high-speed maglev operation and control zoning method, which includes:

[0048] S101. Input a target tracking interval according to the line on-site construction conditions, and determine target parameters in the line on-site construction, wherein the target parameters include parameters of each station, line parameters, and / or train parameters.

[0049] Specifically, in this embodiment, the input setting of the target tracking interval is based on the on-site construction conditions of the line. It should be noted that the target tracking interval input in this embodiment is a standard technical parameter and is generally expressed in whole minutes, such as a 2-minute target tracking interval or a 3-minute target tracking interval. However, during other calculations, the tracking interval can be rounded to one or two decimal places to ensure calculation accuracy. For example, if the target tracking interval is 2.3 minutes, then the technical standard that is met is a 3-minute target tracking interval. At the same time, target parameters such as station parameters, line parameters, and train parameters can be determined based on the on-site construction conditions of the line. Station parameters include, but are not limited to, station length; line parameters include, but are not limited to, road slope and turnout location; and train parameters include, but are not limited to, speed and acceleration. The above target parameters are merely examples for ease of understanding. Other parameters beyond these will be discussed in the detailed process description below.

[0050] S102. Taking the center point of the first station as the first starting point, along the forward running direction of the train, obtain the length of each operation control zone and the position of each operation control zone according to the target tracking interval time and target parameters.

[0051] Specifically, in this embodiment, the first station is the starting station in the line construction, or it can also be the departure station of the train. Taking the center point of the first station as the first starting point, along the forward running direction of the train, the length of each operation control zone and the position of each operation control zone can be calculated according to the target tracking interval time and target parameters, such as Figure 2 The specific process is as follows:

[0052] S1021. Obtain the center point kilometer mark of the first station, obtain the first station partition length according to the target tracking interval time and the target parameters, and obtain the first station partition end kilometer mark according to the first starting point kilometer mark and the first station partition length.

[0053] Specifically, first, for the first station, it is necessary to calculate the station partition length corresponding to the first station, that is, the first station partition length. In this embodiment, the train braking distance can be calculated using the relevant train parameters in the target parameters. The specific calculation process is:

[0054]

[0055] Among them, a 制 is the maximum braking deceleration of the train, and a 制 =d+i·g, d is the train braking deceleration parameter, which can be in the range of 0.2m / s 2 Up to 1.2m / s 2 ; i is the average slope of the braking section where the train is running in thousandths; g is the acceleration due to gravity; V B The normal operating speed of the train.

[0056] Then, the first station partition length can be calculated based on the target tracking interval, target parameters, and train braking distance. The specific process is as follows:

[0057]

[0058] Where t is the given target tracking interval, and the maximum acceleration of the train is a 加 =bc·v+i·g, b is the train acceleration parameter, which can be in the range of 0.5m / s 2 Up to 1.0m / s 2 , c is the air resistance parameter, v is the current speed of the train during calculation. The air resistance of the train is determined by the current speed and wind resistance. i is the average slope of the braking section where the train is running in thousandths; g is the acceleration of gravity; V B is the normal operating speed of the train; L A is the length of the protection zone; L Z is the train length; T H With T R They are stop time and brake reaction time respectively.

[0059] Finally, based on the kilometer mark of the first starting point and the length of the first station section, the kilometer mark of the end point of the first station section can be calculated, thereby determining the length and position of the first station section.

[0060] S1022. Taking the end point of the first station partition as the second starting point, obtaining the length of the departure partition according to the target tracking interval time and the target parameters, and obtaining the kilometer mark of the end point of the departure partition according to the kilometer mark of the second starting point and the length of the departure partition.

[0061] Specifically, after the train leaves the station, it will enter the next partition from the first station partition, which is the departure partition. Figure 3 As shown, the process of calculating the length of the leaving partition in this embodiment is as follows:

[0062] S10221. Calculate the intersection of the train acceleration curve and the train braking curve based on the target parameters, and accelerate the train from the switch speed limit to the normal operating speed. The specific process is as follows:

[0063]

[0064] S10222. Calculate the departure section running time based on the target tracking interval, target parameters, and the intersection of the train acceleration curve and the train braking curve. The specific process is as follows:

[0065]

[0066] Among them, V Y is the intersection of the train acceleration curve and the train braking curve, t is the given target tracking interval, and the maximum acceleration of the train is a 加 =bc·v+i·g, the maximum braking deceleration of the train a 制 =d+i·g, where b is the train acceleration parameter, which can be in the range of 0.2m / s 2 Up to 1.2m / s 2 ; c is the air resistance parameter, the air resistance of the train is determined by the current speed and wind resistance; d is the train braking deceleration parameter, which can be in the range of 0.5m / s 2 ~1.0m / s 2 ; i is the average slope of the braking section where the train is running in thousandths; g is the acceleration due to gravity; V ST Speed limit for trains leaving the branch; V B is the normal operating speed of the train; L A is the length of the protection zone; T D With T R They are system delay and brake reaction time respectively.

[0067] S10223. Calculate the length of the departure section based on the running time of the departure section and the time required for the train to accelerate from the switch speed limit to the normal operating speed.

[0068] Here, for the departure section running time t 离 And the time t required for the train to accelerate from the switch speed limit to the normal operating speed a There are two possible relationships between the two. One is t 离 ≥t a , the other is t 离 <t a , these two situations need to be discussed and calculated separately.

[0069] For t 离 ≥t a When , the corresponding leaving partition length calculation process is as follows:

[0070]

[0071] For t 离 <t a When , the corresponding leaving partition length calculation process is as follows:

[0072]

[0073] Among them, the maximum acceleration of the train is a 加 =bc·v+i·g, where b is the train acceleration parameter, which can be in the range of 0.2m / s 2 Up to 1.2m / s 2 ; c is the air resistance parameter, which is determined by the current speed and wind resistance; i is the average slope of the braking section where the train is running in thousandths; g is the acceleration due to gravity; V ST Speed limit for trains leaving the branch; V B The normal operating speed of the train.

[0074] S10224. Obtain the kilometer mark of the end point of the departure partition according to the kilometer mark of the second starting point and the length of the departure partition, thereby determining the length and position of the departure partition.

[0075] S1023. Obtain the center point kilometer mark of a second station adjacent to the first station, and calculate the positional relationship between the center point kilometer mark of the second station and the kilometer mark of the end point of the departure zone;

[0076] S1024. Determine the length and position of the second station partition according to the positional relationship between the center point kilometer mark of the second station and the end kilometer mark of the departure partition.

[0077] Specifically, during the on-site construction of the line, there may be two situations: the first station and the second station are farther apart or closer. When the first station and the second station are closer, the length of the aforementioned departure zone may cover the center kilometer mark of the second station, that is, the kilometer mark at the end of the departure zone is located in front of the kilometer mark at the center of the second station. However, when the first station and the second station are farther apart, the kilometer mark at the center of the second station is located in front of the kilometer mark at the end of the departure zone. For these two situations, separate calculations need to be performed to determine the length and location of the second station zone, and further analysis can be performed to determine whether there are other transportation control zones between the first station and the second station.

[0078] More specifically, if the departure zone's end kilometer marker is ahead of the second station's center kilometer marker, this means that when the train leaves the first station, it will not be able to accelerate to its normal operating speed in the departure zone and will enter the second station. In this case, there is no need to set up a departure zone between the first and second stations. Instead, the departure zone between the second station and the first station should be treated as the second station zone, and the departure zone's end kilometer marker should be the second station's center kilometer marker.

[0079] If the kilometer mark of the end point of the departure zone is behind the kilometer mark of the center point of the second station, it indicates that there are other transport control zones that can be split between the departure zone and the second station. Therefore, this embodiment first uses the end point of the departure zone as the third starting point, obtains the main line zone length according to the target tracking interval time and target parameters, and obtains the kilometer mark of the end point of the main line zone according to the kilometer mark of the third starting point and the main line zone length. Figure 4 As shown in the figure, the process of calculating the kilometer mark of the end point of the main line partition is as follows:

[0080] S10241. Calculate the minimum braking distance of the train based on the target parameters, specifically:

[0081] L min =L 制 +L 安

[0082]

[0083] L 安 =V B ·T R +L 其他

[0084] Where t is the given target tracking interval, and the maximum braking deceleration of the train is a 制 =d+i·g, d is the train braking deceleration parameter, which can be in the range of 0.5m / s 2 Up to 1.0m / s 2; i is the average slope of the braking section where the train is running in thousandths; g is the acceleration due to gravity; V B is the normal operating speed of the train; L 其他 It is a fixed value, determined by combining the experience of on-site personnel; T R is the braking reaction time.

[0085] S10242. Obtain the mainline section length L based on the target tracking interval, target parameters, and minimum train braking distance. 正 :

[0086]

[0087] Where t is the given target tracking interval, T D is the system delay, V T is the main line partition speed; V B is the normal operating speed of the train; L A is the length of the protection zone; L Z is the train length.

[0088] S10243. Obtain the kilometer mark of the end point of the main line partition according to the kilometer mark of the third starting point and the length of the main line partition, thereby determining the length and position of the main line partition.

[0089] Similar to the departure zone, the positional relationship between the mainline zone and the second station may also vary. However, unlike the departure zone, the positional relationship between the mainline zone and the second station is not just about which comes first and which comes after. It also requires calculating whether the distance between the mainline zone and the second station meets the safe operating distance. Therefore, this embodiment requires calculating the positional relationship between the mainline zone's terminal kilometer marker and the second station's center kilometer marker. Based on this positional relationship, the number of mainline zones and the length and location of the second station zone are determined.

[0090] When the distance between the kilometer mark of the end point of the main line section and the kilometer mark of the center point of the second station exceeds a preset threshold (usually for operational safety, the threshold can be set to 2 braking distance lengths), the above calculation process is used to calculate the next main line section length with the end point of the main line section as the starting point until the distance between the kilometer mark of the last main line section end point and the kilometer mark of the center point of the second station is less than the preset threshold.

[0091] When the distance between the kilometer mark at the end of the main line partition and the kilometer mark at the center of the second station is less than a preset threshold, the end of the main line partition is used as the fourth starting point, and referring to the process of S102, the length of the second station partition is obtained according to the target tracking interval time and the target parameter, and the kilometer mark at the end of the second station partition is calculated according to the fourth starting point and the length of the second station partition, thereby finally determining the length and position of the second station partition. Figure 5 The diagram shows a complete operation control division diagram, which includes the first station zone, the departure zone, the main line zone (which can be one or more), and the second station zone. According to the above description of this embodiment, the existence of the departure zone and the main line zone can be adjusted according to the distance between the first station and the second station, which will not be repeated here.

[0092] During a train's operation, a train departs from its originating station and arrives at its final destination. There may be intermediate stations between the originating and final destinations, or the originating and final destinations may be adjacent. Further analysis is required for both scenarios.

[0093] If the second station is not the train's final destination, it indicates that the train will continue to depart from the second station and proceed to the next station after arriving at the second station. Therefore, it is necessary to divide the operation control zone in front of the second station. The division process is basically the same as the operation control zone division between the first and second stations described above. Starting from the center point of the second station, the departure zone length in front of the second station is calculated based on the target tracking interval and target parameters until the train reaches the final destination. Finally, the division calculation of the length and location of all operation control zones for the line construction site is completed.

[0094] The high-speed maglev operation and control zoning method of this embodiment uses the target tracking interval as input based on the line construction conditions and determines the target parameters for line construction. The target parameters include parameters for each station, line parameters, and / or train parameters. Taking the center point of the first station as the first starting point, the length and position of each operation and control zone are obtained along the forward direction of the train based on the target tracking interval and target parameters. The present invention enables the train to derive the length and position of each operation and control zone based on the target tracking interval, and flexibly adjust the power supply zone length according to the needs of line construction, thereby integrating the operation and control zone with the power supply zone.

[0096] Corresponding to Example 1, this embodiment provides a high-speed maglev operation control zoning system, the system including a processor configured with processor-executable operation instructions to perform the following method:

[0097] Input a target tracking interval according to the line site construction conditions, and determine target parameters in the line site construction, the target parameters including parameters of each station, line parameters and / or train parameters;

[0098] Taking the center point of the first station as the first starting point, along the forward running direction of the train, the length and position of each operation control zone are obtained according to the target tracking interval time and target parameters. The first station is the starting station in the on-site construction of the line.
