[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The method of the embodiment of the present invention can be applied in traffic scenarios, achieving accurate and reasonable adjustment of train capacity, and effectively improving the operational efficiency and economy of the line.

[0023] In the related technologies, passenger congestion is easily caused during peak passenger flow periods. Therefore, how to effectively match capacity and passenger flow based on the existing train autonomous operation system and improve the operational efficiency of urban rail transit is a technical problem that technicians in this field need to solve urgently.

[0024] The train running interval adjustment method and device of the embodiment of the present invention realizes more accurate and reasonable adjustment of train capacity by real-time monitoring and analyzing the passenger flow congestion of the entire running line, and adjusts the time interval of trains according to the passenger flow congestion of the entire running line, thereby effectively improving the operating efficiency and economy of the line.

[0025] Combine the following Figure 1-Figure 4 The technical solution of the present invention is described in detail with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0026] Figure 1 1 is a flow chart of an embodiment of a method for adjusting train running intervals provided by an embodiment of the present invention. Figure 1 As shown, the method provided in this embodiment includes: Step 101: Obtain passenger flow data of each station on the running line.

[0027] Specifically, the passenger flow data of each station in the operating line can be obtained through the data collected by the station gate and / or the camera device; for example, the passenger flow data counted by the station gate and the passenger flow data collected by the camera device are compared, and the larger value of the two is used as the passenger flow data of the station.

[0028] Step 102: Determine the passenger congestion of each station based on the passenger flow data of each station; and determine the passenger congestion of the operating line based on the passenger flow congestion of each station.

[0029] Specifically, after obtaining the passenger flow data of each station in the operating line, the passenger flow congestion of the operating line can be determined based on the passenger flow data of each station; optionally, a running line may include multiple stations, and the passenger flow congestion of a single station cannot accurately and comprehensively reflect the passenger flow congestion of the entire running line. Therefore, it is not accurate and reasonable to adjust the capacity based on the passenger flow congestion of a single station. Therefore, in this application, the passenger flow congestion of the running line is determined according to the passenger flow data of each station, and then the capacity is adjusted based on the passenger flow congestion of the entire running line. It is more accurate and reasonable, and it is more effective to match the capacity and passenger flow, and improve the operational efficiency of urban rail transit. That is, based on the relationship between the whole and the part, the passenger flow congestion of each station is first determined, and then based on the passenger flow congestion of each station, the passenger flow congestion of the entire running line can be accurately and quickly determined, which effectively improves the efficiency and accuracy of determining the passenger flow congestion of the overall line. Optionally, the passenger flow congestion of all stations in the running line may be averaged, or the passenger flow congestion data of some passenger stations may be screened out from all passenger stations to characterize the passenger flow congestion of the entire running line.

[0030] Step 103: Adjust the train running interval in the running line according to the passenger flow congestion of the running line.

[0031] Optionally, after determining the passenger congestion of the entire running line, the train running interval can be adjusted based on the passenger congestion of the entire running line, so as to achieve the coordination and matching of passenger flow and capacity, achieve the effect of fully utilizing the train capacity, and effectively improve the operational efficiency of urban rail transit. That is, by real-time monitoring and analysis of the passenger flow of the entire line, when the line has a passenger flow peak, the train operation timetable is regenerated, the train operation time interval is adaptively adjusted, the line passenger capacity is improved, the train operation time interval is extended during the low passenger flow period, the line operation energy consumption is reduced, and the line operation efficiency and economy are effectively improved.

[0032] The method of the above embodiment first determines the passenger congestion of each station, and then based on the passenger congestion of each station, the passenger congestion of the entire running line can be accurately and quickly determined, and the time interval of the trains is adjusted according to the passenger congestion of the entire running line, thereby achieving more accurate and reasonable adjustment of the train capacity and effectively improving the operating efficiency and economy of the line.

[0033] In one embodiment, the passenger flow congestion degree of each station is determined according to the passenger flow data of each station, including: The passenger congestion of each station is determined based on the following method: ; Among them, X represents the passenger congestion of the station; represents the congestion coefficient; P represents the passenger flow data of the station; S represents the area of ​​the waiting hall in the station.

[0034] Specifically, in the embodiment of the present application, the passenger congestion of the station is determined based on the number of passengers in the station and the area of ​​the waiting area in the station; optionally, the number of passengers in the station can be divided by the area of ​​the waiting area in the station to obtain the number of passengers per unit area in the waiting area, that is, the passenger flow density, which is then multiplied by a preset congestion coefficient to obtain the passenger congestion of the station, thereby achieving accurate representation of the passenger congestion of the station and providing accurate basic data for calculating the passenger congestion of the entire operating line.

[0035] In one embodiment, determining the passenger flow congestion of the running line according to the passenger flow congestion of each station includes: Binarize the passenger flow congestion of each station to obtain the processed passenger flow congestion of each station; The passenger congestion degree of the operating line is determined based on the accumulated results of the processed passenger congestion degrees of each station.

[0036] Specifically, after accurately representing the passenger congestion of the station based on the number of passengers at the station and the area of ​​the waiting hall in the station, the passenger congestion of each station is further binarized in the embodiment of the present application to obtain the processed passenger congestion of each station, thereby simplifying the representation of the passenger congestion of the station, and can more quickly calculate the passenger congestion of the entire operating line, thereby improving the adjustment efficiency of the train running interval.

[0037] For example, the passenger congestion of each station can be binarized in the following manner: when the passenger congestion X is less than or equal to 0.5, the passenger congestion after binarization is set to 0; when the passenger congestion X is greater than 0.5, the passenger congestion after binarization is set to 1, which effectively simplifies the representation of passenger congestion, and can more quickly calculate the passenger congestion of the entire running line, thereby improving the adjustment efficiency of the train running interval.

[0038] Optionally, after the passenger flow congestion of each station is binarized to obtain the processed passenger flow congestion of each station, in the embodiment of the present application, the passenger flow congestion of each station after the binarization processing is accumulated to obtain the cumulative result of the passenger flow congestion of the station, and the cumulative result of the passenger flow congestion of the station is used as the passenger flow congestion of the entire operating line.

[0039] For example, when the entire operating route includes three passenger stations, if the passenger flow congestion of passenger station 1 is 1, if the passenger flow congestion of passenger station 2 is 1, if the passenger flow congestion of passenger station 3 is 1, then the passenger flow congestion of the entire operating route is 3; if the passenger flow congestion of passenger station 1 is 0, if the passenger flow congestion of passenger station 2 is 0, if the passenger flow congestion of passenger station 3 is 0, then the passenger flow congestion of the entire operating route is 0; if the passenger flow congestion of passenger station 1 is 1, if the passenger flow congestion of passenger station 2 is 1, if the passenger flow congestion of passenger station 3 is 0, then the passenger flow congestion of the entire operating route is 2, thereby achieving accurate characterization of the passenger flow congestion of the entire operating route.

[0040] The method of the above embodiment, on the one hand, simplifies the representation of the passenger congestion of the station by binarizing the passenger congestion of each station, and can more quickly calculate the passenger congestion of the entire running line, thereby improving the efficiency of adjusting the train running interval. On the other hand, the passenger congestion of each station after the binarization process is accumulated, and the accumulated result of the passenger congestion of each station is used as the passenger congestion of the entire running line, which accurately and efficiently represents the passenger congestion of the entire running line based on the passenger congestion of each passenger station, and provides an accurate basis for adjusting the train interval of the entire running line.

[0041] In one embodiment, adjusting the train running interval in the running line according to the passenger flow congestion of the running line includes: When the passenger flow congestion of the running line is greater than a first threshold, waking up the dormant trains and / or shortening the train running interval; When the passenger congestion of the running line is less than a second threshold, the train is put into sleep mode and / or the train running interval is extended; the second threshold is less than the first threshold.

[0042] Specifically, after determining the passenger congestion of the running line according to the passenger flow data of each station, if the passenger congestion of the running line is greater than the first threshold, the embodiment of the present application will wake up the dormant train to increase the capacity, so that the capacity and passenger flow are more matched, and the carrying capacity and operating efficiency of the line are improved; optionally, the carrying capacity can also be increased by shortening the train running interval; that is, the adjustment of the capacity and the adjustment of the running interval can be achieved in a variety of ways, making the capacity adjustment method more flexible and diverse, and effectively ensuring the solution to the passenger congestion problem. Optionally, the second threshold can be the number of stations in the entire running line; for example, if the number of stations in the entire running line is 10, the second threshold can be 10.

[0043] Optionally, when the passenger congestion of the operating line is less than a second threshold, some trains will be put into sleep mode and / or the train operating interval will be extended in the embodiment of the present application, so as to more effectively match the transport capacity and passenger flow and reduce the operating cost.

[0044] The method of the above embodiment, when the passenger flow congestion of the running line is greater than the first threshold, wakes up the dormant train and / or shortens the train running interval, and adjusts the transport capacity and the running interval in a variety of ways, thereby realizing flexible adjustment of transport capacity based on a variety of ways, and effectively ensuring the solution of the passenger flow congestion problem. When the passenger flow congestion of the running line is less than the second threshold, the dormant train and / or the train running interval are extended, so that the transport capacity and passenger flow can be matched more effectively, reducing the operating cost.

[0045] In one embodiment, obtaining passenger flow data of each station in the running line includes: The passenger flow data of each station on the running line is obtained based on the data collected by the station gate and / or camera device.

[0046] Specifically, in the embodiment of the present application, the passenger flow data of each station in the operating line is obtained based on the data collected by the station gate and / or the camera device; optionally, the larger of the user passenger flow data collected by the station gate and the camera device can be used as the passenger flow data of the station, or the average of the user passenger flow data collected by the station gate and the camera device can be used as the passenger flow data of the station, thereby achieving accurate acquisition of the passenger flow data of each station, providing comprehensive and accurate passenger flow data for the calculation of the congestion of the entire operating line, and effectively improving the accuracy of the adjustment of the train running interval.

[0047] For example, Figure 2 As shown, a train running interval adjustment device is also provided in an embodiment of the present application. The train running interval adjustment device described below and the train running interval adjustment method described above can refer to each other.

[0048] The train running interval adjustment device provided in this embodiment includes: The passenger flow data collection module 210 is used to obtain the passenger flow data of each station in the running line; The passenger flow data analysis module 220 is used to determine the passenger flow congestion of each station according to the passenger flow data of each station; and determine the passenger flow congestion of the running line according to the passenger flow congestion of each station; The automatic train monitoring module 230 is used to adjust the train running interval in the running line according to the passenger flow congestion.

[0049] Optionally, the passenger flow data analysis module 220 is specifically used for: The passenger congestion of each station is determined based on the following method: ; Among them, X represents the passenger congestion of the station; represents the congestion coefficient; P represents the passenger flow data of the station; S represents the area of ​​the waiting hall in the station.

[0050] Optionally, the passenger flow data analysis module 220 is specifically used for: Binarize the passenger flow congestion of each station to obtain the processed passenger flow congestion of each station; The passenger congestion degree of the operating line is determined based on the accumulated results of the processed passenger congestion degrees of each station.

[0051] Optionally, the train automatic monitoring module 230 is specifically used for: When the passenger flow congestion of the running line is greater than a first threshold, waking up the dormant trains and / or shortening the train running interval; When the passenger congestion of the running line is less than a second threshold, the train is put into sleep mode and / or the train running interval is extended; the second threshold is less than the first threshold.

[0052] Optionally, the passenger flow data collection module 210 is specifically used for: The passenger flow data of each station on the running line is obtained based on the data collected by the station gate and / or camera device.

[0053] Exemplarily, the train running interval adjustment device performs the following adjustment process on the train running interval: (1) The passenger flow data collection module collects real-time passenger flow data from the station's video surveillance system, automatic ticket collection system (AFC) gates and other equipment, and uploads the passenger flow data to the passenger flow data analysis module at fixed time intervals. By rationally arranging the cameras of the video surveillance system in the waiting area of ​​the station, the passenger flow data collection module uses an intelligent video analysis algorithm to count the number of passengers waiting in each station hall in real time; the AFC gate can count the passenger flow in and out of each station in real time; when the passenger flow counted by both increases significantly, it indicates that the current period has entered the passenger flow peak period, thereby realizing accurate and rapid acquisition of passenger flow data for each station.

[0054] (2) After receiving the passenger flow data from each station, the passenger flow data analysis module calculates the passenger flow congestion of each station on the line, and judges the passenger flow congestion status of the entire line based on this, and transmits the passenger flow congestion status data of the entire line to the train automatic monitoring module.

[0055] For example, the passenger flow data analysis module calculates the passenger congestion of each station hall based on the number of passengers waiting in the station. The number of passengers per unit area is defined as the passenger congestion of the station hall X, that is,

[0056] Among them, P is the number of passengers; S is the passenger waiting area; μ is the congestion coefficient, which is the reciprocal of the maximum number of passengers that a unit waiting area can carry. It can take different values ​​depending on the station hall layout and equipment configuration. For example, for a station hall equipped with platform screen doors, μ can take a smaller value.

[0057] The congestion degree of the station hall passenger flow is X∈[0,1]. The larger the value, the more crowded the station hall is. The congestion degree of the station hall passenger flow is calculated based on the all-day passenger flow statistics, and the congestion degree curve of the station hall passenger flow can be generated. Taking the all-day operation of a subway station as an example, Figure 3 This is the passenger congestion curve of the station hall during the operation of the subway station.

[0058] When the congestion degree of passenger flow in the station hall is X ≤ 0.5, it is determined that the passenger flow is smooth and the passenger comfort is good; when X>0.5, it is determined that the passenger flow is crowded and the passenger comfort is poor. The passenger flow data analysis system converts the congestion degree of passenger flow in the station hall into the digital quantity of passenger flow in the station hall, that is, when X ≤ 0.5, the digital quantity of passenger flow is set to 0, and when X>0.5, the digital quantity of passenger flow is set to 1.

[0059] (3) The automatic train monitoring module regenerates the train timetable during peak passenger flow hours based on the dynamic data of passenger congestion in the station halls of all stations along the line, and retransmits the timetable to the on-board control system to wake up the necessary dormant trains and put them into operation, or to take some trains out of operation during non-peak hours, thereby achieving adaptive adjustment of train running intervals.

[0060] For example, the line passenger flow digital quantity LP is defined as

[0061] Among them, N is the total number of stations on the line, seats; Xⅈ is the passenger flow digital quantity of station i.

[0062] The train automatic monitoring module sets the passenger flow threshold lptv for the entire line. If the current passenger flow digital quantity X of more than half of the stations is 1, it can be considered that the passenger flow of the entire line is large, that is, when LP>=lptv, it is considered that the line has a passenger flow peak. The train automatic monitoring module automatically determines whether the entire line has a passenger flow peak based on the calculated passenger flow digital quantity of all stations on the entire line, and sends instructions to the operating train accordingly: wake up the line, maintain operation, and train offline, and coordinate with all other online running trains to adaptively adjust the running time. Once the train automatic monitoring module detects that there is a passenger flow peak on the line, it will immediately wake up the dormant train and put it into operation to increase the transport capacity; at the same time, the train-to-ground wireless transmission system transmits the line passenger flow digital quantity to the on-board system in real time, and all online running trains adjust the train running time interval adaptively based on the received passenger flow digital quantity information and the interactive train operation information.

[0063] The device of the above-mentioned embodiment, on the technical architecture of the existing TACS system for autonomous adjustment of train operation, constructs a passenger flow data collection module and a passenger flow data collection module, uses the station video monitoring system and the AFC gate to collect passenger flow data, and monitors the passenger flow of the entire line in real time. When there is a passenger flow peak, the train automatic monitoring module ATS will adjust the train operation schedule in time, wake up the dormant trains to enter the running state to increase the transportation capacity; all online trains will exchange train operation information according to the latest train operation schedule adjusted and generated by ATS, and adaptively adjust the train operation time interval; by shortening the train operation time interval during peak passenger flow periods, the line passenger carrying capacity is improved, and by extending the train operation time interval during low passenger flow periods, the line operation energy consumption is reduced, which can effectively improve the line operation efficiency.
