Embodiment 1
[0025] figure 1 It is a schematic flow chart of Embodiment 1 of the automatic control method for railway access according to the present invention. As shown in the figure, the flow chart includes:
[0026] Step S11, sending the shunting operation instruction to the analytical control device and the train terminal;
[0027] The shunting operation instruction can be generated in, for example, a railway transportation scheduling management computer, and the shunting operation instruction can include instruction serial number, train identification information (such as locomotive number), operation type (pick-up or trailer), operation start and end information , the vehicle number of the operation (or the number of vehicles for the operation) and other information, can be made into a shunting operation instruction format table by manually formulating a table, as shown in Table 1 below:

Embodiment 2
[0037] The second embodiment of the automatic control method for the railway route of the present invention is as follows: figure 1 On the basis of the shown embodiment, the search for the optimal path in step S13 also specifically includes: figure 2 The following steps are shown:
[0038] Step S201 , searching out the shortest path between the starting point of the operation and the ending point of the operation from the roadmap database; and finding the shortest path according to the Floyd algorithm. That is, each track unit in the roadmap database is initialized first, and then all paths from the starting point to the end point are calculated, and iterative until the shortest path is found.
[0039] In step S201, the optimal solution of the route can be quickly found by traversing the road map by applying the Floyd algorithm, and the route selection problem of the railway transportation network can be dynamically solved. The specific process is as follows:
[0040] Let c...
Embodiment 3
[0047] The third embodiment of the automatic control method for the railway route of the present invention is as follows: figure 1 On the basis of the illustrated embodiment, the search for an optimal path in step S13 specifically includes the following: image 3 The following steps are shown:
[0048] Step S301, searching for the shortest path between the starting point of the operation and the ending point of the operation from the roadmap database;
[0049]Step S302, detecting the track circuit occupancy status information of the interlocking area in the shortest path;
[0050] Step S303, determine whether the shortest path interlocking area is occupied, if not, then perform step S304 to output the shortest path as a better path; if it is occupied, then perform step S305, search for the second shortest between the starting point and the ending point. path;
[0051] Step S306, it is judged whether the time required for searching the second shortest path is shorter than th...
