In urban rail transit systems, periods of high passenger flow in both directions are often high, such as holidays, major events, morning and evening rush hours, natural disasters, or traffic accidents. At transfer stations and integrated transportation hubs, passenger flows from different directions and along different routes can easily intersect, creating large passenger flows in both directions. In such cases, for safety and operational efficiency reasons, it is necessary to avoid the simultaneous arrival of large trains in both directions with load factors exceeding a threshold.

[0004] To achieve the above object, the present invention provides a method for avoiding the simultaneous arrival of bidirectional high-passenger flow trains, comprising the following steps:

[0005] Step 1: The train automatic monitoring system obtains the passenger flow information of the station. When the passenger flow of the station is greater than the set threshold, the platform with large passenger flow is located. 、 ;

[0006] Step 2: Periodically monitor platforms with large passenger flows to see if there are trains entering the station from both directions at the same time or if there are overlapping stops. If so, mark the up and down trains as 、 ;

[0007] Step 3: Detect platforms with large passenger flow 、 Type;

[0008] Step 4: If a platform with large passenger flow is detected 、 If the platform is an island platform and there are trains from both directions entering the station at the same time or their stops overlap, the strategy set is generated based on the positions of the trains in both directions to determine whether they enter the avoidance zone.

[0009] Step 5: Select the corresponding handling strategy from the strategy set based on the train's location, and automatically push the handling strategy to the dispatcher for confirmation;

[0010] Step 6: After the dispatcher confirms, the train automatic monitoring system automatically controls the train according to the handling strategy.

[0011] Furthermore, in step 4, the range of the avoidance area can be set, and the bidirectional trains in the avoidance area are classified as follows:

[0012] C1: Upward train and down trains All are located at platforms with large passenger flow 、 Countdown phase for the pit stop;

[0013] C2: The first up train to arrive On a platform with high passenger flow During the countdown period for the stop, the down train that arrives later On a platform with high passenger flow The adjacent interval ;

[0040] The preferred structure and implementation method of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] like Figures 1 to 6 As shown, an embodiment of the present invention discloses a technical solution for a method of avoiding the simultaneous arrival of bidirectional large passenger flow trains at a station. Example 1

[0042] The present invention provides a method for avoiding the simultaneous arrival of large passenger flow trains in both directions. The train scheduling flow chart based on passenger flow and train operation system analysis is as follows: Figure 1 As shown, the following steps are included:

[0043] Step 1: The train automatic monitoring system obtains the passenger flow information of the station. When the passenger flow of the station is greater than the set threshold (the threshold can be set), the platform with large passenger flow is located. 、 ;like Figure 2, red marks are platforms with large passenger flow in the up and down directions;

[0044] Step 2: Periodically monitor platforms with large passenger flows to see if there are trains entering the station from both directions at the same time or if there are overlapping stops. If so, mark the up and down trains as 、 ;

[0045] Overlapping stop times is considered the key to avoiding simultaneous arrival of trains in both directions. If the stop times of two trains at the same station overlap, then there must be a period of time when both trains are at the platform at the same time. First, find the arrival time of the two trains at the platform with large passenger flow based on the forecast. The time when the train that arrives first arrives at the platform with large passenger flow is , the time it takes for the next train to arrive at the platform with large passenger flow is , and then find out the planned stop time of the two trains at the platform with large passenger flow according to the forecast. The planned stop time of the train arriving first at the platform with large passenger flow is The planned stop time of the later arriving train at the platform with large passenger flow is , the basis for judging whether the two trains will overlap at a platform with large passenger flow is as follows:

[0046] ,

[0047]

[0048] Step 3: Detect platforms with large passenger flow 、 Type;

[0049] Step 4: If a platform with large passenger flow is detected 、 If the platform is an island platform and there are trains from both directions entering the station at the same time or their stops overlap, the strategy set is generated based on the positions of the trains in both directions to determine whether they enter the avoidance zone.

[0050] Step 5: Select the corresponding handling strategy from the strategy set based on the train's location, and automatically push the handling strategy to the dispatcher for confirmation;

[0051] Step 6: After the dispatcher confirms, the train automatic monitoring system automatically controls the train according to the handling strategy. Example 2

[0052] The steps of this embodiment are basically the same as those of embodiment 1, except that in step 4, the range of the avoidance area can be set. For example, if you want to avoid simultaneous arrival within the range of three stations in both directions, you can use 3 as configuration information and store it in the configuration file. This can support avoidance processing for different needs.

[0053] like Figure 2, the avoidance area settings are:

[0054] (1) Upward direction: from the previous platform To the platform with large passenger flow .

[0055] (2) Downward direction: from the previous platform To the platform with large passenger flow .

[0056] When there is a large passenger flow at the platform, the trains in the avoidance area are classified as follows:

[0057] C1: Upward train and down trains All are located at platforms with large passenger flow 、 Countdown phase for the pit stop;

[0058] C2: The first up train to arrive On a platform with high passenger flow During the countdown period for the stop, the down train that arrives later On a platform with high passenger flow The adjacent interval ;

[0059] C3: Upward train On a platform with high passenger flow The adjacent interval , down train On a platform with high passenger flow The adjacent interval ;

[0060] C4: The first up train to arrive The platform before the platform with high passenger flow , the down train arriving later In the section before the platform before the platform with large passenger flow ;

[0061] C5: The first up train to arrive In the avoidance area, except for the platform with large passenger flow Nearby interval Other intervals outside , the down train arriving later In the avoidance area, except for the platform with large passenger flow Nearby interval Other intervals outside Starting platform Countdown phase for the stop. ;

[0062] C6: The first up train to arrive In the avoidance area, except for the platform with large passenger flow Nearby interval Other intervals outside , the down train arriving later In the avoidance area, except for the platform with large passenger flow Nearby interval Other intervals outside , ;

[0063] C7: The first arriving up train In the avoidance area, except for the platform with large passenger flow , the platform before the platform with large passenger flow Other platforms During the countdown period for the stop, the down train that arrives later In the avoidance area, except for the platform with large passenger flow , the platform before the platform with large passenger flow Other platforms The previous interval , .

[0064] The above-mentioned C1-C7 location classification radiates from the busiest passenger flow station to both sides.

[0065] In step 4, the policy set includes:

[0066] D1: Adjust the up train and down trains The running time of the train and the stopping time at stations with large passenger flow;

[0067] D2: The train is detained for a limited time. The train automatic monitoring system automatically calculates the detention time. After the detention time expires, the train automatic monitoring system automatically cancels the detention.

[0068] D3: Depart immediately;

[0069] D4: Set up the up train or down train Cross the station.

[0070] In step 5, based on the train's location, the corresponding handling strategy is selected from the strategy set to comprehensively regulate the train operation, forming the following processing scenarios:

[0071] S1: When the train's position is C1 and there are no restrictions, the handling strategy is to take the first arriving up train. At a platform with large passenger flow Execute the immediate departure strategy;

[0072] S2: When the train position is C2 and there are no restrictions, the handling strategy is down train At a platform with large passenger flow Over the station;

[0073] S3: When the train position is C3, and the constraint condition is to adjust the up train At a platform with large passenger flow and down trains At a platform with large passenger flow When the trains arrive at the station at the same time, the handling strategy is to At a platform with large passenger flow Over the station;

[0074] S4: When the train position is C3, and the constraint condition is to adjust the up train At a platform with large passenger flow and down trains At a platform with large passenger flow When the stop time of the train can be completely avoided from arriving at the station at the same time, the handling strategy is to adjust the up train At a platform with large passenger flow and down trains At a platform with large passenger flow Stop time;

[0075] S5: When the train position is C4 and there are no restrictions, the handling strategy is down train On the platform before the high-traffic platform Limited time vehicle impoundment;

[0076] S6: When the train position is C5 and there are no restrictions, the handling strategy is to adjust the up train Ending station in the section The stop time and the departure time from the platform arrive The running time of the next stop;

[0077] S7: When the train position is C6 and there are no restrictions, the handling strategy is to adjust the down train End platform in the section The stop time and the departure time from the platform arrive The running time of the next station and the adjustment of the up train Ending station in the section The stop time and the departure time from the platform arrive The running time of the next stop;

[0078] S8: When the train position is C7 and there are no restrictions, the handling strategy is to adjust the down train Ending station in the section The stop time and the departure time from the platform arrive The running time of the next station.

[0079] The above processing scenarios S1-S8 radiate from the high passenger flow station to both sides. If scenario S1 is not satisfied, it will continue to determine whether scenario S2 occurs, and so on, until a suitable scenario is found and the train is processed accordingly.

[0080] The present invention provides a method for avoiding the simultaneous arrival of bidirectional large passenger flow trains at a station. By correspondingly avoiding the simultaneous arrival of bidirectional large passenger flow trains with a full load rate exceeding a threshold, the hidden dangers of chaotic passenger flow and congestion and trampling on the platform are eliminated; the normal operation of bidirectional trains is ensured; and the waiting time of passengers on the platform increased due to passenger congestion is reduced. The train automatic monitoring system promptly provides a strategy for avoiding the simultaneous arrival of bidirectional large passenger flow trains at a station, and automatically adjusts the train after confirmation by the dispatcher, thereby eliminating the lag of manual intervention.
