In the urban rail transit system, holidays, large-scale events, morning and evening rush hours, natural disasters or traffic accidents are all high-incidence periods for large passenger flow in both directions. At transfer stations and comprehensive transportation hubs, passenger flows from different directions and lines are also prone to interweaving, forming large passenger flows in both directions. In this case, for the sake of safety and operational efficiency, it is necessary to avoid the simultaneous arrival of large passenger flow trains in both directions with full load rates exceeding the threshold. Summary of the invention

[0004] To achieve the above object, the present invention provides a method for avoiding simultaneous arrival of bidirectional large passenger flow trains, comprising the following steps: 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. , ; Step 2: Periodically monitor the platforms with large passenger flow to see if there are trains in both directions entering the station at the same time or if there are overlapping stop times. If so, mark the up and down trains as , ; Step 3: Detect platforms with large passenger flow , Type; 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 the stop times overlap, the strategy set is generated based on the positions of the trains from both directions to determine whether they enter the avoidance area. Step 5: According to the location of the train, select the corresponding disposal strategy from the strategy set, and automatically push the disposal strategy to the dispatcher for confirmation; Step 6: After the dispatcher confirms, the train automatic monitoring system automatically controls the train according to the handling strategy.

[0005] 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: C1: Upward train and down trains All are located at high passenger flow platforms , Countdown phase for the stop; C2: The first up train to arrive At a high passenger flow platform During the countdown period of the stop, the down train that arrives later At a high passenger flow platform The adjacent interval ; C3: Upward train At a high passenger flow platform The adjacent interval , down train At a high passenger flow platform The adjacent interval ; C4: The first up train to arrive The platform before the platform with large passenger flow , the down train arriving later The section before the platform before the platform with large passenger flow ; C5: The first up train to arrive Except for platforms with large passenger flow, Nearby interval Other intervals outside , the down train arriving later Except for platforms with large passenger flow, Nearby interval Other intervals outside Starting station Countdown phase for the stop. ; C6: The first up train to arrive Except for platforms with large passenger flow, Nearby interval Other intervals outside , the down train arriving later Except for platforms with large passenger flow, Nearby interval Other intervals outside , ; C7: The first up train to arrive Except for platforms with large passenger flow, , the platform before the platform with large passenger flow Other platforms During the countdown period of the stop, the down train that arrives later Except for platforms with large passenger flow, , the platform before the platform with large passenger flow Other platforms The previous interval , .

[0006] Furthermore, in step 4, the policy set includes: D1: Adjust the up train and down trains The running time of the train and the stopping time at stations with large passenger flow; D2: The train is detained for a limited time. The train automatic monitoring system automatically calculates the detention time. After the detention time is over, the train automatic monitoring system automatically cancels the detention. D3: Depart immediately; D4: Set up the up train or down train Cross station.

[0007] Furthermore, in step 5, according to the position of the train, a corresponding handling strategy is selected from the strategy set to form the following processing scenario: S1: When the train position is C1 and there are no restrictions, the handling strategy is to take the first arriving up train. At a high passenger flow platform Execute the immediate departure strategy; S2: When the train position is C2 and there are no restrictions, the handling strategy is down train At a high passenger flow platform Over station; S3: When the train position is C3, and the constraint condition is to adjust the up train At a high passenger flow platform Downward train At a high passenger flow platform When the stop time of the train cannot be completely avoided and the trains arrive at the station at the same time, the handling strategy is to At a high passenger flow platform Over station; S4: When the train position is C3, and the constraint condition is to adjust the up train At a high passenger flow platform and down trains At a high passenger flow platform When the stop time of the train can completely avoid simultaneous arrival at the station, the handling strategy is to adjust the up train At a high passenger flow platform and down trains At a high passenger flow platform Stop time; 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 car seizure; S6: When the train position is C5 and there are no restrictions, the handling strategy is to adjust the up train End station in section The stop time and the departure time from the platform arrive The running time of the next stop; S7: When the train position is C6 and there are no restrictions, the handling strategy is to adjust the down train End station in section The stop time and the departure time from the platform arrive The running time of the next station, adjust the up train End station in section The stop time and the departure time from the platform arrive The running time of the next stop; S8: When the train position is C7 and there are no restrictions, the handling strategy is to adjust the down train End station in section The stop time and the departure time from the platform arrive The running time of the next station.

DETAILED DESCRIPTION

[0011] The preferred mechanism and implementation method of the present invention are further described below in conjunction with the accompanying drawings and specific implementation methods.

[0012] 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

[0013] The present invention provides a method for avoiding the simultaneous arrival of bidirectional large passenger flow trains. The train dispatching flow chart based on passenger flow and train driving system analysis is as follows: Figure 1 As shown, the following steps are included: 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; Step 2: Periodically monitor the platforms with large passenger flow to see if there are trains in both directions entering the station at the same time or if there are overlapping stop times. If so, mark the up and down trains as , ; The overlapping stop times are considered to be the key to avoid the 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 out the arrival time of the two trains at the platform with large passenger flow according to the forecast. The time when the first train arrives at the platform with large passenger flow is , the time 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 first train 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 that the two trains will overlap in their stop time at a platform with large passenger flow is as follows: ,

[0014] Step 3: Detect platforms with large passenger flow , Type; 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 the stop times overlap, the strategy set is generated based on the positions of the trains from both directions to determine whether they enter the avoidance area. Step 5: According to the location of the train, select the corresponding disposal strategy from the strategy set, and automatically push the disposal strategy to the dispatcher for confirmation; Step 6: After the dispatcher confirms, the train automatic monitoring system automatically controls the train according to the handling strategy. Example

[0015] 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 simultaneous arrival avoidance is to be performed within the range of three stations in both directions, 3 can be used as configuration information and stored in the configuration file. This can support avoidance processing for different needs.

[0016] like Figure 2 , the avoidance area settings are: (1) Upward direction: from the previous platform To the platform with large passenger flow .

[0017] (2) Downward direction: from the previous platform To the platform with large passenger flow .

[0018] When there is a large passenger flow at the platform, the trains in the avoidance area are classified as follows: C1: Upward train and down trains All are located at high passenger flow platforms , Countdown phase for the stop; C2: The first up train to arrive At a high passenger flow platform During the countdown period of the stop, the down train that arrives later At a high passenger flow platform The adjacent interval ; C3: Upward train At a high passenger flow platform The adjacent interval , down train At a high passenger flow platform The adjacent interval ; C4: The first up train to arrive The platform before the platform with large passenger flow , the down train arriving later The section before the platform before the platform with large passenger flow ; C5: The first up train to arrive Except for platforms with large passenger flow, Nearby interval Other intervals outside , the down train arriving later Except for platforms with large passenger flow, Nearby interval Other intervals outside Starting station Countdown phase for the stop. ; C6: The first up train to arrive Except for platforms with large passenger flow, Nearby interval Other intervals outside , the down train arriving later Except for platforms with large passenger flow, Nearby interval Other intervals outside , ; C7: The first up train to arrive Except for platforms with large passenger flow, , the platform before the platform with large passenger flow Other platforms During the countdown period of the stop, the down train that arrives later Except for platforms with large passenger flow, , the platform before the platform with large passenger flow Other platforms The previous interval , .

[0019] The above-mentioned C1-C7 location classification radiates from the bus station with large passenger flow to both sides.

[0020] In step 4, the policy set includes: D1: Adjust the up train and down trains The running time of the train and the stopping time at stations with large passenger flow; D2: The train is detained for a limited time. The train automatic monitoring system automatically calculates the detention time. After the detention time is over, the train automatic monitoring system automatically cancels the detention. D3: Depart immediately; D4: Set up the up train or down train Cross station.

[0021] In step 5, according to the location of the train, the corresponding disposal strategy is selected from the strategy set to comprehensively regulate the train operation, forming the following processing scenarios: S1: When the train position is C1 and there are no restrictions, the handling strategy is to take the first arriving up train. At a high passenger flow platform Execute the immediate departure strategy; S2: When the train position is C2 and there are no restrictions, the handling strategy is down train At a high passenger flow platform Over station; S3: When the train position is C3, and the constraint condition is to adjust the up train At a high passenger flow platform and down trains At a high passenger flow platform When the stop time of the train cannot be completely avoided and the trains arrive at the station at the same time, the handling strategy is to At a high passenger flow platform Over station; S4: When the train position is C3, and the constraint condition is to adjust the up train At a high passenger flow platform and down trains At a high passenger flow platform When the stop time of the train can completely avoid simultaneous arrival at the station, the handling strategy is to adjust the up train At a high passenger flow platform and down trains At a high passenger flow platform Stop time; 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 car seizure; S6: When the train position is C5 and there are no restrictions, the handling strategy is to adjust the up train End station in section The stop time and the departure time from the platform arrive The running time of the next stop; S7: When the train position is C6 and there are no restrictions, the handling strategy is to adjust the down train End station in section The stop time and the departure time from the platform arrive The running time of the next station, adjust the up train End station in section The stop time and the departure time from the platform arrive The running time of the next stop; S8: When the train position is C7 and there are no restrictions, the handling strategy is to adjust the down train End station in section The stop time and the departure time from the platform arrive The running time of the next station.

[0022] The above processing scenarios S1-S8 radiate from the station with large passenger flow 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.

[0023] The present invention provides an avoidance disposal method for simultaneous arrival of bidirectional large passenger flow trains at a station. By performing corresponding avoidance on simultaneous arrival of bidirectional large passenger flow trains with full load rates exceeding a threshold, hidden dangers of chaotic flow of passengers on a platform and crowded trampling of passengers are eliminated; the normal operation of bidirectional trains is ensured; and the increased waiting time of passengers on the platform due to crowded passenger flow is reduced; the train automatic monitoring system timely provides a avoidance disposal strategy for simultaneous arrival of bidirectional large passenger flow trains at a station, and automatically adjusts the train after confirmation by a dispatcher, thereby eliminating the lag of manual intervention.
