Description
Technical Field
The invention belongs to the field of high-speed railways/intercity railway platform doors, and particularly relates to a platform door design method based on vehicle type projection distribution and a high-speed railway platform door.
Background
The high-speed rail in China has high running density and short stop time, a train passes through the high-speed rail at high speed, the platform generates obvious pneumatic effect, the passenger flow at the platform is high at the peak time, and potential safety hazards exist when passengers wait for the train, so that the waiting safety of the passengers can be endangered in strong wind convection weather. However, the high-speed rail has a high speed grade, and the motor train unit is operated in a cross-line mode, so that the adaptation of different motor train units and platform doors becomes a technical bottleneck restricting the popularization and application of the platform doors in the high-speed rail. As the high-speed rail network operation and part of the busy main line passenger flow become saturated, the pressure of high-speed rail station service safety protection increases day by day.
In order to improve the adaptive capacity of the high-speed rail platform door, the inventor group develops a front-back staggered high-speed rail platform door as disclosed in chinese patent application No. CN 111980541A. The high-speed rail platform door can completely meet the requirement of stopping various high-speed rail train types in China, and is self-adaptive to the movable door with the corresponding opening degree opened at the position of the train door after the train stops. However, considering that the length of the domestic high-speed rail platform is generally 450 meters, if the total station platform adopts an adaptive front-back staggered high-speed rail platform door or a double-side telescopic mobile high-speed rail platform door, a huge cost rise is brought. Therefore, how to design the high-speed rail platform door in a customized manner at the high-speed rail station platform and remarkably reduce the manufacturing cost on the basis of meeting the use requirement of the high-speed rail platform becomes a problem to be solved urgently.
Disclosure of Invention
In order to solve the technical problems, the invention provides a platform door design method based on vehicle type projection distribution, and aims to reduce the construction cost of a high-speed rail platform door.
The invention is realized by adopting the following technical scheme:
the platform door design method based on vehicle type projection distribution comprises the following steps:
step S1, acquiring the number of platforms of a station, wherein the number of the platforms is more than or equal to 1;
step S2, obtaining all train information of the station according to the train dispatching information, wherein the train information comprises vehicle type information and marshalling information, and classifying the trains with the same vehicle type information and the same marshalling information into the same class;
step S3, counting the position coordinates of all doors of each train by taking the initial position of each train as an origin; aligning the initial positions of all the trains, and projecting the position coordinates of all the vehicle doors to the same coordinate axis;
step S4, calculating the proximity of the positions of the doors of all the trains projected to the coordinate axis, classifying the trains with the proximity meeting the preset requirement as a large train class, and dividing all the train classes into a preset number of large train classes;
step S5, distributing the trains stopping at the station to each platform of the station according to the types of the trains, aligning the platform stop marking line with the initial position of the trains for each platform, and arranging platform doors along the platform; the platform door is configured to: along the direction of the platform, the corresponding position of each vehicle door gathering area is a movable door, and the rest positions are fixed doors.
Optionally, if the number of platforms of the station =1, the preset number of the large class of trains = 1. Namely, the station only has a single platform, so that the train is not required to be classified into a large class.
Optionally, if the number of platforms of the station is greater than 1, calculating the number ratio of the stop times of each train class, wherein the number ratio of the stop times is the ratio of the stop times of all trains of the train class to the stop times of all trains; the number of the stop stations of each train is the integer result of the product of the stop number ratio of the train and the number of the stations.
The significance of the large-class train division is as follows: and (4) considering from the level of the multi-platform high-speed rail station, dividing the train types adjacent to the distribution positions of the doors according to the information of the train types. Therefore, the parking vehicle types of all the platforms of the station are as consistent as possible, and the total opening degree of the platform door movable door of each platform is as small as possible, so that the aim of reducing the construction cost on the basis of not reducing the parking requirements of various vehicle types of high-speed rails is fulfilled.
In consideration of the quantity difference of high-speed rail vehicles running on line, the frequency of the large train entering and exiting stations is more than that of the large trains of other trains, and if platforms are averagely distributed to each large train, the number of receiving and sending stations of each platform of a station is unbalanced, so that the overall running efficiency of the station is reduced. Therefore, the invention reasonably distributes the platforms for the large classes of trains with similar proximity according to the stop number ratio by introducing the stop number ratio of the large classes of trains, balances the number of trains of receiving and delivering stations of each platform door and improves the overall efficiency of the stations.
Further, the proximity calculation method is as follows: and calculating the total offset of the vehicle doors of two rows of vehicles from the initial position, wherein the total offset of the vehicle doors is the sum of the offsets of the vehicle doors of the corresponding serial numbers.
Further, only calculating the sum of the door offset of the corresponding vehicles of the two trains; the door offset of a non-corresponding vehicle is set to 0. For example, 8 consist trains are adjacent to 16 consist trains, and only the total door offset of the first 8 consist trains from the start position, both of which correspond to the sequence number, is calculated. The scheme can optimally divide the large class of trains without being limited by the change of the marshalling form for flexibly marshalling the trains in the future.
Further, the step S5 of laying the platform doors along the platform includes: clustering the vehicle door positions of all train types projected to the coordinate axis to form a plurality of vehicle door collective areas along the coordinate axis from the initial position, wherein the clustering standard is that the width range of any vehicle door collective area is less than the distance between the vehicle door collective area and the adjacent vehicle door collective area; and arranging a movable door corresponding to the position of each vehicle door assembly area from the position of a parking mark line along the platform, wherein the maximum opening degree of the movable door corresponds to the width of the vehicle door assembly area.
The significance of clustering the positions of the vehicle doors is to optimize the proportion of the fixed doors and the movable doors of the platform doors of a single platform and determine the opening range of each movable door. The clustering criterion of the width range of any vehicle door collective area being less than the distance between the vehicle door collective area and the adjacent vehicle door collective area ensures that all the movable doors can cover the opening positions of the vehicle doors of all train types stopped at the platform, and the opening degree of the single movable door is limited in a limited range. For example, for a certain platform, due to newly adding a vehicle type 1, a vehicle door position 1 is added between two vehicle door assembly areas: the way that can be taken is: clustering the position of the vehicle door and the adjacent vehicle door assembly area again to form a new vehicle door assembly area, wherein the new vehicle door assembly area is feasible if the new vehicle door assembly area meets the clustering standard; and if the new vehicle door assembly area does not meet the clustering standard, the vehicle door position is automatically formed into a vehicle door assembly area of 1.
Optionally, the movable door includes, but is not limited to, a front-back split-level moving type, a double-side telescopic moving type or a vertical lifting type.
The Chinese patent application No. CN111980541A filed by the applicant is cited in a front-back staggered platform door mode; the Chinese patent application No. CN111547070A filed by the applicant is cited in a double-side telescopic movable platform door mode; the vertical lifting type platform door comprises a bottom lifting type platform door independently developed by the applicant, when the unit door is lifted, the platform door is closed, and when the unit door is descended to the middle of the foundation pit, the platform door is closed.
In another aspect, the present invention provides a high-speed railway platform door, which is designed and manufactured by the above design method.
Compared with the prior art, the invention has the beneficial effects that:
based on station scheduling information, vehicle door distribution similarity division is firstly carried out on train types of a stop station in a vehicle type projection mode, so that the train types with similar vehicle door distribution stop at the same platform; and then carrying out vehicle door position clustering on the trains distributed to the same platform so as to determine the opening degree of the movable door of the platform. Based on the train classification and the vehicle door position clustering, the optimal configuration with the least number of movable doors/the best opening degree considered from the global perspective of the station is realized, the construction cost of the platform door system is obviously reduced, and meanwhile, the stability of the platform door system is also improved due to the increase of the number of the fixed doors.
In addition, the invention distributes the platforms with the corresponding quantity proportion for the large class of trains based on the stop frequency proportion of the large class of trains, thereby realizing the balance of the train receiving and sending loads of each platform on the basis of reducing the construction cost of the movable door.

Detailed Description
Example 1
Embodiment 1 provides a method for designing a platform door based on a vehicle type projection distribution, as shown in fig. 1, including:
step S1, acquiring the number of platforms of a station, wherein the number of the platforms is more than or equal to 1;
step S2, obtaining all train information of the station according to the train dispatching information, wherein the train information comprises vehicle type information and marshalling information, and classifying the trains with the same vehicle type information and the same marshalling information into the same class;
step S3, counting the position coordinates of all doors of each train by taking the initial position of each train as an origin; aligning the initial positions of all the trains, and projecting the position coordinates of all the vehicle doors to the same coordinate axis;
step S4, calculating the proximity of the positions of the doors of all the trains projected to the coordinate axis, classifying the trains with the proximity meeting the preset requirement as a large train class, and dividing all the train classes into a preset number of large train classes;
step S5, distributing the trains stopping at the station to each platform of the station according to the types of the trains, aligning the platform stop marking line with the initial position of the trains for each platform, and arranging platform doors along the platform; the platform door is configured to: along the direction of the platform, the corresponding position of each vehicle door gathering area is a movable door, and the rest positions are fixed doors.
The number of the platforms of the station is more than 1, and the number ratio of the stopping times of each large train is calculated, wherein the number ratio of the stopping times of all the trains of the large train is the ratio of the stopping times of all the trains; the number of the stop stations of each train is the integer result of the product of the stop number ratio of the train and the number of the stations. After the stations are allocated, a large group of vehicles all stop at fixed stations, all of the vehicles having the same or similar dimensions. For example, if the number of stops of a certain train class is about 60%, and the number of platforms at the station is 5, 3 platforms are allocated to the train class.
Fig. 2 is a schematic diagram showing the distribution of the doors of the train classified into the same train after the proximity is calculated. The calculation mode of the proximity is as follows: and calculating the total offset of the vehicle doors of two rows of vehicles from the initial position, wherein the total offset of the vehicle doors is the sum of the offsets of the vehicle doors of the corresponding serial numbers. Only calculating the sum of the door offset of the corresponding vehicles of two trains; the door offset of a non-corresponding vehicle is set to 0. For example, 8 consist trains are adjacent to 16 consist trains, and only the total door offset of the first 8 consist trains from the start position, both of which correspond to the sequence number, is calculated. And if the proximity threshold value is 1.6m, and the total door offset of the front 8 marshalling rows of the doors is less than or equal to 1.6m, the doors are classified into the same train category. Of course, proximity may also be defined as a threshold amount of door offset per vehicle that substantially coincides with the door offset.
Step S5 includes the platform door along the platform: clustering the vehicle door positions of all train types projected to the coordinate axis to form a plurality of vehicle door collective areas along the coordinate axis from the initial position, wherein the clustering standard is that the width range of any vehicle door collective area is less than the distance between the vehicle door collective area and the adjacent vehicle door collective area; and arranging a movable door corresponding to the position of each vehicle door assembly area from the position of a parking mark line along the platform, wherein the maximum opening degree of the movable door corresponds to the width of the vehicle door assembly area. Fig. 3 is a distribution diagram of multi-vehicle type door projection projected to a certain platform, and fig. 4 is a layout diagram of platform doors based on the multi-vehicle type door projection distribution, wherein the numbers marked on the movable doors are the opening degree of each movable door, and the numbers marked on the coordinate axes are the initial positions of each movable door along the platform.
The significance of clustering the positions of the vehicle doors is to optimize the proportion of the fixed doors and the movable doors of the platform doors of a single platform and determine the opening range of each movable door. The clustering criterion of the width range of any vehicle door collective area being less than the distance between the vehicle door collective area and the adjacent vehicle door collective area ensures that all the movable doors can cover the opening positions of the vehicle doors of all train types stopped at the platform, and the opening degree of the single movable door is limited in a limited range. For example, for a certain platform, due to newly adding a vehicle type 1, a vehicle door position 1 is added between two vehicle door assembly areas: the way that can be taken is: clustering the position of the vehicle door and the adjacent vehicle door assembly area again to form a new vehicle door assembly area, wherein the new vehicle door assembly area is feasible if the new vehicle door assembly area meets the clustering standard; and if the new vehicle door assembly area does not meet the clustering standard, the vehicle door position is automatically formed into a vehicle door assembly area of 1.
The movable door includes, but is not limited to, a front-back staggered floor moving type, a bilateral telescopic moving type or a vertical lifting type.
