DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
Fig. 1 shows a specific flow of the method for acquiring and expressing operation information of a level crossing according to the present invention, in which a process of an acquisition cycle is shown;
fig. 2 shows the range of the acquisition area of the level crossing. The train speed and position information of each period in the range can be expressed on an actual operation chart. The inter-zone traveling track outside the area range is represented by the connection line of the station or level crossing point information at the two ends;
as shown in fig. 3 (a) and 3 (b), the left side is a conventional operation diagram, and the right side is an expression method of the operation diagram considering the level crossing factor. The position, the phase and the information of the passing train of the level crossing can not be known in the traditional operation diagram, and after the expression of stations (station A and station B) of the level crossing is added, the position of the level crossing, the signal lamp phase change information of each level crossing and the operation information of the passing train of the level crossing can be displayed.
As shown in fig. 4, which is an example of an expression method of a running chart in consideration of a level crossing factor, a line a is train running plan information, and a line B is train running actual information.
Fig. 5 shows a tramcar operation adjustment flowchart designed based on an operation diagram in consideration of a level crossing factor.
Fig. 6 is an exemplary illustration of a tramcar operation adjustment method designed based on an operation diagram considering the factors of a level crossing, and the arrangement situation of the station and the level crossing is the same as that in fig. 3:
first, an embodiment of laying a planned operation line and an actual operation line of an operation diagram in consideration of a level crossing factor will be described.
Referring to fig. 4, a black line is a planned travel line laid at a moment of the basic diagram, and a red line is an actual travel line. As can be seen from the black line, the arrival and departure schedule times of the stations are shown in table 1:

Station B [t1,t2]
First station (level crossing) [t3,t4]
Station C [t5,t6]
Second station (level crossing) [t7,t8]
Station D [t9,t10]
As shown in fig. 4, the tramcar is delayed from the departure time a to t0 'due to the influence of the late point of the preceding train, and when the tramcar starts from the station B and arrives at the first station (level crossing), the tramcar just touches the red light, starts to stop at the time t3' and waits, and after the time t3 'becomes the green light, the tramcar starts to pass through the first station (level crossing) and leaves the first station at the time t 4'. Because of the delay in the start, the train also encounters a red light by the time it arrives at station b, and likewise needs to stop waiting.
As can be seen from fig. 4, the ratio of the planned time for each station in the scheduled time to the arrival and departure times of the actual operation diagram is shown in table 2:
TABLE 2
Station Scheduled runtime Actual operating time
Station A [-,t0] [-,t0’]
StationB [t1,t2] [t1’,t2’]
First station (level crossing) [t3,t4] [t3’,t3”,t4’]
Station C [t5,t6] [t5’,t6’]
Second station (level crossing) [t7,t8] [t7’,t7”,t8’]
Station D [t9,t10] [t9’,t10’]

Referring to fig. 6, a first station and a second station are added on a traditional operation diagram to represent two level crossing respectively, and the fixed phase time of the traffic lights of the level crossing first and second stations is marked on the operation diagram. Next, the operation adjustment of the train Y will be described as an example.

4 Station C [t5,t6]
5 Station D [t7,t8]
6 Second station (level crossing) [t9,t10,t11]
