Problems solved by technology

[0004] Full-time signal control personnel manually arrange the opening of the interlocking access area according to the train call according to the order, which is not efficient and cannot guarantee safety and reliability. The dependence on personnel is prone to man-made accidents
[0005] Train monitoring is assisted by Global Positioning System (GPRS) or Radio Frequency Technology (RFID), which is very expensive to build and maintain. It is impossible to know the number and identity information of trains running on the railway using simple track circuit detection technology. Insufficient guiding significance of organizational management

Embodiment 1

[0025] figure 1 It is a schematic flow chart of Embodiment 1 of the railway route automatic control method of the present invention, as shown in the figure, the process includes:

[0026] Step S11, sending the shunting operation instruction to the analysis control device and the train terminal;

[0027] The shunting operation instruction can be generated in, for example, the railway transportation dispatching management computer, and the shunting operation instruction can include instruction sequence number, train identification information (such as locomotive number), operation type (picking or trailer), operation start point and operation end point information , operating vehicle number (or the number of operating vehicles), etc., can be manually compiled into a shunting operation instruction format table, as shown in Table 1 below:

[0028]

[0029] Table 1 Shunting operation instruction format

[0030] After the preparation is completed, the shunting operation instruc...

Embodiment 2

[0037] The second embodiment of the railway route automatic control method of the present invention is figure 1 On the basis of the illustrated embodiment, the search for a better path in step S13 also specifically includes the following figure 2 The following steps are shown:

[0038] Step S201, searching the shortest path between the starting point and the ending point of the operation from the road map database; finding the shortest path according to the Floyd algorithm. That is to initialize each track unit in the road map database, and then calculate all paths from the starting point to the end point, and iterate until the shortest path is found.

[0039] In step S201, the optimal solution of the route can be quickly found through the traversal search of 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 be the cost matrix of n×...

Embodiment 3

[0047] The third embodiment of the railway route automatic control method of the present invention is figure 1 On the basis of the illustrated embodiment, in step S13, the search for a better path 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 end point of the operation from the road map database;

[0049]Step S302, detecting the track circuit occupancy state information of the interlocking area in the shortest path;

[0050] Step S303, judge whether the shortest path interlocking area is occupied, if not, execute step S304 and output the shortest path as a better path; if occupied, execute step S305, search out the second shortest path between the starting point and the end point path;

[0051] Step S306, judging whether the time required to search for the next shortest path is shorter than the time occupied by the interlocking area in the sh...

Abstract

The invention discloses a method for automatically controlling the railway route entry, which comprises the following steps: transmitting a shunting service instruction to analyzing equipment and a train terminal; transmitting an instruction to the analyzing control equipment to determine information after receiving the shunting service instruction by the train terminal; searching a higher preference path from a road map database according to the shunting service instruction after receiving the instruction determining information by the analyzing control equipment; and transmitting a control instruction to interlocking control equipment for opening a route entry according to the higher preference path. The invention also discloses a device for realizing the method, which comprises the train terminal, the analyzing control equipment and the interlocking control equipment. By the method and the device, the arrangement of artificial participation of train route entry can be canceled, the automatic arrangement of the higher preference path for route entry can be realized, the traffic capacity of railway can be improved and the labor productivity as well as the automatic level and the safe reliability of the railway can be improved.

Description

technical field [0001] The invention relates to a railway route control system, in particular to a railway route automatic control method and device. Background technique [0002] As railway transportation becomes more and more complex, it presents the characteristics of automation and networking. How to achieve higher transportation efficiency and safety reliability is a problem that the transportation control system needs to solve. This objectively requires reducing personnel participation and realizing automatic control and dynamic tracking of the vehicles in operation. For example, the process railway transportation of large industrial and mining enterprises, especially the timeliness requirements of molten iron, molten steel, and steel products of iron and steel enterprises, requires real-time tracking of rolling stock information and automated management of traffic command. There are many forks in the national railway transportation network, and the logical relations...
