Hereinafter, the operation of each component of the track information generation management device 40 will be described in detail. First, the operation of the CAD file converting means 41 will be described.

The CAD file converting means 41 is responsible for automatically converting the CAD file having the line drawings into a file of the line information generating means 43. Automatic conversion of CAD files increases worker's work efficiency and enables them to cope quickly with environmental changes such as line changes. The main function of the CAD file converting means 41 converts the CAD file into the file format of the line information generating means 43, and converts data related to the line drawing of the CAD file into the line drawing file storing means 44 into a database format. Save as. In addition, all elements that make CAD drawings are first expressed in blocks, secondly, they do not contain blocks within the blocks, and thirdly, texts, straight lines, rectangles, and ellipses never block. Low, naming, and fifth, there are several conditions that require distinction between elements and comments. In accordance with the above constraints, detailed constraints on elements such as platform, segment, signal, track changer, grounder, career separator, and terminal included in the track drawing were defined.

The function of the CAD file converting means 41 is the same as that shown in FIG. As shown in the drawing, the CAD file is loaded from the storage means in which the CAD file is stored, and then the CAD file is imported. Then, when the loading of the CAD file is confirmed, the track drawing file is generated and finished.

Next, the operation of the line drawing editing means 42 will be described.

The line drawing editing means 42 has a function of correcting a data entry error of the line drawing file generated by converting the CAD file or directly creating a line drawing. The data entered in the track diagram becomes the basic data for generating track information data.

The line drawing editing means 42 connects the data structure of each element with a linked list, starting from the left side of the line drawing drawn on the work area and moving to the right side. Since the data structure is processed by the line information generating means 43, only a simple connection list is generated without applying a complicated connection data structure.

The operation of the line drawing editing means 42 is the same as the flowchart shown in FIG. As shown, the line drawing editing means 42 opens or creates a line drawing file, and then performs data structure creation and initial operations.

Thereafter, after performing the element editing step, it is determined whether to add an element, and if there is no element to be added, the process proceeds to determining whether to close the file as described below.

However, if there is an element to be added, it initializes the element data structure and judges whether or not to save the file, and when not saving the file, proceeds to the step of determining whether to close the file as described below. If it is to be saved, it is added to the track drawing data structure, and then it is decided to save the track drawing file and then decide whether to close the file.

If the file is not closed at the step of determining whether to close the file, the process returns to the element editing step again, repeats the subsequent operation, and ends after closing all files after editing all the elements.

Next, the operation of the line information generating means 43 will be described.

The track information generating means 43 serves to generate a data structure and output data using the data generated and modified by the track drawing editing means 42. To accomplish this role, five data structures are created: basic data structure, element concatenation, route tree, route line, and route list. Here, the basic data structure stores the connection relation of elements based on reverse information. Element linkage stores the linkage of each element. The root tree is a tree-type data structure that stores segment data between terminal → terminal, terminal → off page, off page → terminal, and off page → off page. To perform. The root line functions to create a linked list data structure that stores all the careers based on the tree structured career data structure. The route list is a data structure that stores segment data between career delimiters and stores the final career desired by the user. In addition, the data output function is added to output the data file required for the simulation device (simulator) by referring to the data structure created above.

The data structure of the line information generating means 43 is generated in the order of a basic data structure, a data structure for storing element connection information, a root tree, a root line, and a root list from the line drawing file as shown in FIG.

FIG. 6 is a flowchart showing a basic data structure of FIG. 5. Creating a basic data structure first loads a project file whose track structure has been changed, loads a track drawing file from it, and then creates a reverse data structure, and then determines whether an element exists. If it is determined in the above step that the element exists, the element data is connected to the inverse information data structure, and it is determined whether the next element exists and the element data is connected to the inverse information data structure for all elements. After completing the operation of connecting the element data to the inverse information data structure for all elements as described above, it is determined whether the next line drawing exists, and if the next line drawing exists, the line drawing file is loaded. Repeats the operation of connecting element data to. In addition, even when it is determined that the element does not exist in the step of determining whether the element exists, it is determined whether the next line drawing exists, and if the next line drawing exists, the track drawing file is loaded as described above. The process of linking element data to the information data structure is repeatedly performed. If it is determined that the next line drawing does not exist, the basic data structure creation operation is terminated.

Finally, the operation of the line information output means 45 will be described.

The track information output means 45 can be used by the ATS 10, ATC 20, the interlocking device 30, and other service devices that control and manage the train operation using the data structure created by the track information generating means 43.
