It should be understood that, based on the simulation of the rail transit operation scheme and the passenger flow data, only the operation scheme simulation diagram and the operation scheme analysis index within the preset time range need to be obtained, and as the rail transit system correspondingly implementing the rail transit operation scheme is also in actual operation based on the scheme while the rail transit operation scheme is obtained, and an emergency may occur at any time in the operation process, the analysis and prediction of the actual situation can be realized only by the simulation within the preset time range (for example, 1h) in advance compared with the actual situation, so that the reliability of the analysis result of the rail transit operation scheme is improved, and the useless work is avoided.
In the embodiment of the application, the way of obtaining the analysis result of the rail transit operation scheme by making according to the operation scheme simulation diagram and the operation scheme analysis index may be that after the operation scheme simulation diagram is obtained, coordinate information included in the operation scheme simulation diagram is determined, and then after the operation scheme analysis index is obtained, the operation scheme analysis index is projected and displayed at a corresponding position of the operation scheme simulation diagram according to the coordinate information, so that the operation scheme simulation result is used as the analysis result of the rail transit operation scheme, and the simulation result of the operation scheme is displayed more visually.

Referring to fig. 3, in a possible embodiment, the track transportation operation scheme includes a normal track transportation operation scheme, and the step S102 may include the following specific embodiments.
And a substep S102-1, analyzing the normal rail traffic operation scheme to obtain a train number list.
And a substep S102-2 of receiving field operation data corresponding to the normal rail transit operation scheme.
And a substep S102-3, constructing an initial simulation driving scene according to the field operation data and the train number list.
And a substep S102-4, carrying out driving simulation on the passenger flow volume data and the initial simulation driving scene within a preset time range to obtain a normal operation scheme simulation diagram corresponding to the normal rail transit operation scheme and a normal operation scheme analysis index.
As described above, each area to which each rail transit system belongs has a corresponding normal rail transit operation scheme every day, and the computer device 100 synchronously simulates the normal rail transit operation scheme within a preset time range while the normal rail transit operation scheme is actually executed. For example, after the normal track transportation operation scheme is obtained, the normal track transportation operation scheme may be analyzed to obtain a train number list (e.g., train number, starting station, passing station, ending station, running time of each section, stop time of each station, etc.). And then, current field operation data can be collected, and an initial simulation driving scene is constructed based on the train number list and the field operation data obtained by analysis. And after the construction is finished, adding the acquired passenger flow volume data for simulation. The simulation speed can be much higher than the real operation speed, so that a normal operation scheme simulation diagram and a normal operation scheme analysis index corresponding to a normal rail transit operation scheme within a preset time range can be obtained. The normal operation scheme simulation graph and the normal operation scheme analysis indexes can be visually displayed, so that a dispatcher can directly and frequently see the operation state within the preset time range. It should be understood that in the embodiment of the present application, the field operation data may include train data information and track status information, such as the location of the train on the line, the speed of each train, acceleration, traction brake condition, the location of each switch, the location of each button at the station, etc. In the embodiment of the present application, the passenger flow volume data may also be collected in real time, which is not limited herein. In this embodiment of the application, the computer device 100 may further be communicatively connected to the front-end user interaction interface to display the analysis result of the rail transit operation scheme to the front end for the scheduler to view, and the basic data, such as fixed route data, required in the process of building the initial simulation driving scenario may be stored in the database in advance for scheduling, which is not limited herein.
In a possible implementation, the foregoing step S102 may further include the following specific implementation.
And a substep S102-5 of judging whether the analysis index of the normal operation scheme exceeds a preset normal index threshold value.
If so, then sub-step S102-6 is performed.
And a substep S102-6, carrying out abnormity marking on the analysis index of the normal operation scheme.
If not, then sub-step S102-7 is performed.
And a substep S102-7, carrying out normal marking on the analysis index of the normal operation scheme.
Accordingly, the foregoing step S103 can be implemented by the following specific embodiments.
And a substep S103-1, under the condition that the normal operation scheme analysis index has an abnormal mark, highlighting the normal operation scheme analysis index in the rail transit operation scheme analysis result and initiating an alarm.
In the embodiment of the application, simulation is carried out within a preset time range, and whether a preset normal rail transit operation scheme has a problem within the preset time range can be known. In the embodiment of the application, after the normal operation scheme analysis index within the preset time range is obtained through simulation, whether the normal operation scheme analysis index exceeds a preset normal index threshold value or not can be further judged, namely whether an abnormality occurs or not, if the abnormality occurs, the normal operation scheme analysis index can be subjected to abnormality marking, so that the abnormality can be highlighted and an alarm can be initiated in the subsequent rail transit operation scheme analysis result display, and a scheduler can quickly check the abnormality. It should be understood that, in the embodiment of the present application, the number of the normal operation scheme analysis indexes may be multiple, the rail transit operation scheme analysis results may be evaluated from different dimensions, and after the abnormal normal operation scheme analysis indexes are determined, in addition to performing the abnormal marking on the abnormal normal operation scheme analysis indexes, the abnormal normal operation scheme analysis indexes may also be sent to the external scheme generation server 200, so that a worker on the external scheme generation server 200 side can rapidly perform the customization of the emergency operation scheme.
Referring to fig. 4, in a possible embodiment, the track transportation operation scheme includes a plurality of emergency track transportation operation schemes, and the step S102 may be implemented by the following specific embodiments.
And a substep S102-8, simulating the plurality of emergency rail transit operation schemes and passenger flow data to obtain a plurality of emergency operation scheme simulation graphs and a plurality of emergency operation scheme analysis indexes corresponding to the plurality of emergency rail transit operation schemes within a preset time range.
The emergency rail transit operation scheme, the emergency operation scheme simulation diagram and the emergency operation scheme analysis indexes are in one-to-one correspondence.
It should be understood that, in the embodiment of the present application, the received multiple emergency rail transit operation schemes may all come from the external scheme generation server 200, and the reason for triggering the external scheme generation server 200 to generate the multiple emergency rail transit operation schemes may be that, when the normal rail transit operation scheme simulation is performed, a normal operation scheme analysis index with an abnormal mark is found and fed back to the external scheme generation server 200, and the external scheme generation server 200 analyzes the multiple emergency rail transit operation schemes generated by the index according to the normal operation scheme with the abnormal mark. In the actual operation process, after an emergency occurs on the site, the external plan generating server 200 may generate a plurality of emergency rail transit operation plans for a specific situation.
In a possible implementation, the aforementioned step S103 may be implemented by the following steps.
And a substep S103-2 of obtaining an index score corresponding to each analysis index of the emergency operation scheme.
And a substep S103-3, taking the analysis index of the emergency operation scheme with the highest index score as the analysis index of the target emergency operation scheme.
And a substep S103-4 of displaying the target emergency operation scheme analysis index and a target emergency operation scheme simulation chart corresponding to the target emergency operation scheme analysis index as a rail transit operation scheme analysis result.
In the embodiment of the application, in order to be able to handle a relatively comprehensive emergency situation (for example, a large passenger flow in an emergency or abnormal deceleration of a train), a plurality of emergency rail transit operation schemes are generally provided for a dispatcher to select, and the simulation result of each emergency rail transit operation scheme in a preset time is visually displayed based on the emergency operation scheme analysis indexes and the corresponding emergency operation scheme simulation graph through the scheme, so that the dispatcher with rich experience directly selects the scheme, the index score corresponding to each emergency operation scheme analysis index can be obtained according to a preset rule, the emergency operation scheme analysis index with the highest index score is automatically recommended to the dispatcher based on the index score, the determination time of the emergency scheme when the emergency situation occurs is accelerated, and the processing efficiency is improved.
In one possible implementation, the emergency operation scheme analysis indexes comprise passenger flow indexes and driving indexes, the passenger flow indexes are configured with a first weight, and the driving indexes are configured with a second weight; the aforementioned substep S103-2 may be carried out by the following detailed steps.
(1) And acquiring a first index parameter of a passenger flow index and a second index parameter of a driving index, which are included by the analysis indexes of the pending emergency operation scheme.
The analysis index of the undetermined emergency operation scheme is any one of the analysis indexes of the multiple emergency operation schemes.
(2) And taking the sum of the product of the first index parameter and the first weight and the product of the second index parameter and the second weight as an index score corresponding to the analysis index of the pending emergency operation scheme.
In one possible embodiment, the passenger flow index includes the number of affected passengers, the number of stop passengers at the platform, and the full load rate of different sections; the driving indexes comprise travel speed, technical speed, train running speed, station passing capacity, section passing capacity, turn-back capacity, late train number, midway turn-back train number, clear train number, off-line train number, passing train number, cancelled train number and operation kilometer number change.
As described above, the emergency operation plan analysis indexes may include passenger flow indexes and driving indexes, each of which is configured with a first weight and a second weight, and based on the actually displayed first index parameter and second index parameter, and in combination with the first weight and the second weight, an accurate index score can be calculated. It should be understood that, in the embodiment of the present application, each of the passenger flow index and the driving index includes a plurality of sub-indexes as described above, and a corresponding weight may be configured in advance for each sub-index, so that by such design, it is possible to more accurately calculate and obtain an index score with high reliability from a plurality of angles. It should be understood that the aforementioned normal operation scenario analysis indexes may also include the aforementioned passenger flow index and driving index and their respective sub-indexes, which are used as the reference basis for the decision of the dispatcher.
In order to more clearly describe the scheme provided by the embodiment of the present application, the following exemplary overall scheme is introduced.

However, in an emergency, the village line 2110 times of forced stop faults of the trains in the ten-thousand-source street and the village cultural garden (in the uplink direction) occur, and the trains arrive at the late 10 minutes of the village cultural garden station.
After the emergency occurs, the external scenario generation server 200 generates three emergency rail transit operation scenarios and transmits the scenarios to the computer device 100. The first emergency rail transit operation scheme is as follows: 1111 and 1112 vehicle numbers are executed by the spare vehicle E and F, 1113 and 1114 vehicle numbers are executed after the return of the vehicle A and the vehicle C is finished, and the vehicle B and the vehicle D return to the garage after the transportation of the vehicle number on the vehicle is finished. And an emergency rail transit operation scheme II: 1111 and 1112 vehicle numbers are executed by the spare vehicle E and F, the vehicle C is folded back in advance in Tokyo street and is executed by the passenger 1501, the vehicle A and the vehicle B are executed after folding back is finished, and the vehicle D returns to the garage after the vehicle D is transported to the vehicle number. And an emergency rail transit operation scheme III: 1111 and 1112 vehicle numbers are executed by the spare vehicle E, F, 1501 and 1502 vehicle numbers are executed by the vehicle C and the vehicle D which are folded back in advance in the Tokyo street, and 1113 and 1114 vehicle numbers are executed after the vehicle A and the vehicle B are folded back.

And an emergency rail transit operation scheme II: late 3 columns, respectively: 2110 (10 points late), 2111 (8 points late), 2113 (3 points late); 1 column is folded back in midway, and 2112 is folded back in Rongjingtong; the column 6 of the schedule is A, B, C, D, E and F cars respectively; the spare vehicle 2 rows are used, namely, the vehicle E and the vehicle F. And an emergency rail transit operation scheme III: late 2 columns, respectively: 2110 (10 points later), 2111 (8 points later); turning back 2 rows midway, namely 2112 and 2113 in Rongjing east street; the spare vehicle 2 rows are used, namely, the vehicle E and the vehicle F.

The number of the staying people at the platform: the same full load rate as different sections, a fault deduction stage, a parallel deduction system deduces the number of the people staying in the platform, and under the normal condition, the passenger flow prediction system evaluates the number. Operating kilometer number changes: calculating the number of affected passengers (the threshold value is 5 minutes) of the increase or decrease of the number of running kilometers of the new and old running charts (how many km is increased and how many km is decreased): for example, if passenger a is predicted to take 30 minutes from the departure location to the destination, and if it takes 35 minutes due to the malfunction, the passenger belongs to the affected passenger.
