All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention.
The invention discloses a train tracking processing method of a COCC automatic monitoring system, which is characterized in that when the COCC automatic monitoring system is started, whether a path list configuration file pathInfo. xml exists is checked, and if the path list configuration file pathInfo. xml exists, whether the configuration file corresponds to TLE data needs to be further judged. If the pathinfo.xml configuration file does not exist or the configuration file does not completely correspond to the TLE data, after reading the TLE data, obtaining a path list which takes all tracks and turnout equipment as starting points and contains at most a fixed number of equipment through an intelligent search algorithm, and storing the content of the path list into the pathinfo.xml configuration file for the COCC automatic monitoring system to use when running.
Aiming at the situation that a line only sends kilometer posts of the train head and the train tail, the COCC automatic monitoring system automatically searches and obtains an equipment list occupied by the train in the path list according to equipment occupied by the train head and the train tail, and then updates the interface display.
Referring to fig. 1-7, a specific processing flow of the intelligent path search algorithm in the technical solution of the present invention is illustrated:
taking the local route diagram of fig. 7 as an example, the train head occupies the track G6 and the train tail occupies the switch DC1, it is assumed that the system configuration train occupies at most N-3 devices.
First, when reading the line TLE data, a path list having the track G6 as a start point is found by:
step S1, adding a curPath to the to-be-processed Path list toDoList, and adding G6 to the curPath;
step S2, the number of devices currently included in the curPath is 1, the number is smaller than N, and the curDev points to G6;
step S3, searching the next device of G6, finding the track G7, and adding G7 into curPath;
step S4, the number of devices currently included in the curPath is 2, the number is less than N, and the curDev points to G7;
step S5, searching the next device of G7, if no, ending the curPath search;
step S6, curve path: g6- > G7 moves from toDolist into the completed path list pathList; at this point, todoist is empty;
step S7, adding a curPath to the to-be-processed Path list toDoList, and adding G6 to the curPath;
step S8, the number of devices currently included in the curPath is 1, the number is smaller than N, and the curDev points to G6;
s9, searching previous equipment of G6, and finding out a signal machine S4;
s10, searching previous equipment of S4, finding a turnout DC4, and adding DC4 into curPath;
step S11, the number of devices currently included in the curPath is 2, which is smaller than N, and the path curPath: g6- > DC4 copies as a new path, adds to toDoList; curDev points to DC 4;
s12, searching previous equipment of the DC4, finding a turnout DC3, and adding the DC3 into a curPath;
step S13, the number of devices currently included in the curPath is 3, which is equal to N, and the curPath: g6- > DC4- > DC3 is moved from toDolist into completed path list pathList; there is now a path in todoist: g6- > DC 4;
step S14, taking out a path curPath from todoist: g6- > DC4, curDev points to DC 4;
s15, searching reverse equipment of the DC4, finding a turnout DC1, and adding the DC1 into curPath;
step S16, the number of devices currently included in the curPath is 3, which is equal to N, and the curPath: g6- > DC4- > DC1 is moved from toDolist into completed path list pathList; at this point, todoist is empty; the algorithm ends.
When the train state report is received, according to the rail G6 occupied by the train head, a path including the train tail occupied device DC1 is searched in the path list pathList obtained in the previous step, in this example, only one path in the pathList includes DC1, G6- > DC4- > DC1, and the path is returned as the train occupied device list.
While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
