According to the method and the device, the operation simulation is more real by evaluating the related indexes, so that the displayed operation effect and the calculated operation indexes are more accurate.
Based on any of the above embodiments, the step S1 in the method includes:
analyzing the train operation diagram, establishing the matching relation between the train and the path, and establishing a train starting scene based on the matching relation.
Specifically, the running chart analyzing module analyzes the input running chart, establishes the matching relation between the trains and the paths, and is used as the input of the scene generating module, and the scene generating module mainly constructs the starting scene of each train.
According to the train control overall model adjusting method, before the train control overall model is adjusted, the analysis and matching of the operation diagram are carried out in advance, and more accurate train operation initial data are obtained.
Based on any of the above embodiments, the step S2 in the method includes:
screening all non-repetitive stations in the operation line from the train operation diagram;
calculating to obtain the running sequence of the train numbers on all turnouts in the running line according to all unrepeated stations;
and obtaining an occupied train number list by a train number running sequence, acquiring a first train number and an application turnout train number in a running line, comparing the first train number and the application turnout train number with a train safety path respectively, and adjusting the occupied train number list.
Wherein, the screening of all non-repetitive stations in the operation line from the train operation diagram comprises the following steps:
dividing all train numbers according to the operating stations, deleting repeated stations in the train numbers, and storing the division results among the stations;
and counting all the turnouts in the inter-station division result, and calculating to obtain an operating schedule from all the inter-station entrances to all the turnouts.
Wherein, the calculating to obtain the train number operation sequence on all switches in the operation line according to all the unrepeated stations comprises:

waiting the train the safety route extend to arbitrary switch when, will first train number with apply for switch train number and compare, if the same then agree the train passes through arbitrary switch, and will the train number of cars of train is deleted, otherwise refuses the switch of train passes through the request.
Specifically, firstly, all non-repetitive stations in the line are screened out from the operation diagram:
dividing all train numbers by taking the stations as units, wherein the starting point and the end point of each station are stations, and the entering time and the leaving time of each station are the departure time of the previous station and the entering time of the next station; all stations are stored, wherein duplicate stations need to be deleted. For example, the train number 213 and the train number 313 both include stations between the station 1 and the station 2, and only one path exists between the station 1 and the station 2, so that only one time between the station 1 and the station 2 needs to be recorded;
and (4) counting turnout resources in the stations, performing single-vehicle operation simulation by taking the stations as units, and calculating how long time is required from the entrance of the stations to the turnouts respectively. And calculating all the turnout related information between all the stations according to the principle, and storing the turnout related information into the interstation-turnout container.
Secondly, screening the sequence of passing the train number on all the turnouts in the route from the operation diagram:
dividing the train number by taking the inter-station as a unit, and searching for matching the inter-station in an inter-station-turnout container, wherein each train number is formed by a plurality of inter-stations; the starting clock is the departure time of the previous station, and the clock of each train passing through the turnouts is calculated; and sequencing the train numbers according to the clock to obtain and store the train number sequence passing through the turnout.
Furthermore, the opposite direction controller stores train number arrangement containers of all turnouts, and the train number at the first position of the container is the train number which is at the first position at the current moment and occupies the turnouts; after the train successfully applies for the turnout, the container deletes the train number of the train at the moment, and adjusts the occupied train number list; if the train fails to release the turnout (namely the train does not pass through the turnout but does the turnout release operation), the container can add the train number of the train again and is added at the first position of the container; when the safe path of the train extends to a certain turnout, the vehicle-mounted simulation system applies for the resource occupation of the certain turnout to the opposite controller, the opposite controller retrieves a turnout train number sequencing container at the moment, compares the first train number with the train number applying for the turnout, agrees to the application if the first train number is the same, and deletes the train number from the container; if not, the application is rejected.
As an example shown in fig. 4, in the operation diagram, a train 1(102 train numbers) is positioned to a station 1 through turnouts 4 and 3, and a train 2(202 train numbers) is positioned to the station 1 through turnout 3, wherein the departure time of the train number 102 at the station 2 is 14:25:00, the arrival time at the station 1 is 14:30:00, the departure time of the train number 202 at the station 2 is 14:25:00, and the arrival time at the station 1 is 14:31: 45; the calculation is performed in the unit of station 2 to station 1, and the calculated times of departure of the train numbers 102 and 202 through the switch 3 are 14:28:45 and 14:30:00, respectively, so that the train number 102 occupies the switch 3 earlier than the switch 202.
In addition, the train numbers 202 and 102 both go out of the station and perform safety path calculation, the end points of the expected extended safety paths are all point A, but the first dominant train number of the turnout 3 is 102 at the moment, so 202 cannot apply for the resources of the turnout 3, the safety path and the mobile authorization can only extend to point B at the farthest, the train number 102 can smoothly extend the safety path and the mobile authorization to the point A and enter the station in advance, and the simulation system is ensured to run according to the sequence of the train numbers of the operation diagram without running mixedly.
