BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Figure 1 This is the flowchart of the present invention. Detailed implementation manners

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0043] LKJ-15 is a train operation monitoring device, which is a train control system mainly aimed at preventing trains from overrunning signals, running overspeed and assisting drivers in improving their operation capabilities. It is a key device for trains to ensure traffic safety, improve transportation efficiency and save energy.

[0044] LKJ basic data refers to the basic line data of equipment and facilities such as lines, signals, catenaries, and stations included in the "Technical Data of Train Operation Diagram" of the railway administration, as well as the basic operation organization data such as the tracks for receiving and dispatching trains at stations, the distances for driving to align with the marks at special locations, and the sections undertaken by locomotives or multiple units, including LKJ basic operation organization data and LKJ basic line data.

[0045] Such as Figure 1 shown, the method for automatically generating LKJ-15 data includes the following steps

[0046] Step S1): Obtain the original LKJ data and parse out the line information from the original data. The line information includes in-railway lines, line signal information, track information, turnout information, and line facility information;

[0047] Step S2): Generate station data according to the line signal information, track information, turnout information, and line facility information;

[0048] Step S3): Generate line section data according to the line signal information and line facility data;

[0049] Step S4): Generate line data according to the station data and section data and store it;

[0050] Step S5): Obtain the reported railway transportation information, generate route data according to the reported railway transportation information. In this embodiment, through the existing line data, the stations passed by the route and the station sequence can be obtained, and the station sequence is saved into the route data.

[0051] LKJ-15 data includes line data and route data. The line data describes the basic data of line facilities, and the route data is the data describing railway transportation. The two are stored separately, which can well meet the requirements of frequent adjustment and update of the lines.

[0052] The original data in step S1) includes a line table, a station table, a signal aspect table, a track table, a turnout table, and a line facility table; all the lines within the jurisdiction of the railway administration are included in the line table, and the signal aspect table contains signal aspect numbers, mileage, and station information. The line table describes all the lines within the jurisdiction of the railway administration, from which the lines and their information within the railway administration can be obtained. The signal aspect table describes the signal aspect chain and information of a line. The signal aspect table includes signal aspect numbers, mileage, and station information. The station table contains the relationship between the front and rear stations among the stations on a line. The track table describes the corresponding track information within each station to determine the specific position where the train stops. The track information includes track numbers and lengths. The turnout table contains turnout numbers. A turnout is a connecting device that enables rolling stock to transfer from one track to another and is also an important device for realizing track conversion. The line facility table is used to describe the facility data of the corresponding line.

[0053] The generation of station data in step S2) includes the following steps:

[0054] Step P1): Sequentially read the signal aspect table to obtain the station sequence of each line, and generate the departure direction according to the relationship between the front and rear stations in the station table.

[0055] Step P2): Generate station information in sequence according to the station sequence on each line.

[0056] Step P3): Generate the main line data and corresponding siding data of the corresponding station according to each station information.

[0057] In step P2), the generation of the station information includes the following steps;

[0058] Step M1): Establish a receiving unit data storage space and a departure unit data storage space.

[0059] Step M2): Read all the signal aspect information between the home signal and the starting signal within the corresponding station from the signal aspect table, and at the same time obtain the corresponding tracks between the home signal and the starting signal from the track table.

[0060] The home signal is used to protect the station, indicating whether the train can enter the station and the operating conditions when entering the station. The home signal is set at a place not less than 50 meters away from the tip of the outermost home turnout or the fouling mark of the station.

[0061] The starting signal is a signal aspect that indicates whether the train can depart from the station to the section. Starting signals are installed on the main line and arrival / departure lines of the station. In the automatic block and semi-automatic block sections, if the starting signal is open, it is a voucher for occupying the section.

[0062] Step M3): Write the signal information between the home signal and the departure signal and the corresponding track into the data storage space of the receiving unit;

[0063] Step M4): Read all the signal information between the departure signal and the reverse home signal in the corresponding station from the signal table, and at the same time obtain the corresponding tracks between the departure signal and the reverse home signal from the track table;

[0064] Step M5): Write all the signal information between the departure signal and the reverse home signal and the corresponding tracks into the data storage space of the departure unit.

[0065] In step P3), the method for generating main line data includes the following steps:

[0066] Step N1): Establish a main line data storage space according to the main line data range;

[0067] Step N2): Obtain the corresponding line facility data from the line facility table within the main line data range;

[0068] Step N3): Write the signal machine line mileage range and the corresponding line facility data into the main line data storage space.

[0069] The main line data range includes the main line data range of the receiving unit and the main line data range of the departure unit. The main line data range of the receiving unit is between the home signal and the main line departure signal machine, and the main line data range of the departure unit is between the main line departure signal machine and the reverse entry signal. The main line is the line that extends straight into the station.

[0070] In step P3), the method for generating siding data includes the following steps:

[0071] Step T1): Establish a siding data storage space;

[0072] Step T2): Obtain the line facility data in the corresponding siding from the line facility table;

[0073] Step T3): Write the speed limit value of the turnout, the mileage range of the signal machine on the siding and the corresponding line facility data into the siding data storage space.

[0074] When the locomotive enters the siding, it will pass through the turnout in the station. Due to the different lengths or types of the turnout, the speed limits of the turnout are also different. In order to ensure the safe operation of the locomotive in the station, it is necessary to limit the speed of the locomotive when it travels to the turnout.

[0075] The speed limit value of the turnout includes the speed limit value of the turnout of the receiving unit and the speed limit value of the turnout of the departure unit;

[0076] The turnout speed limit value of the train receiving unit is the lowest value of the turnout speed limit for all locomotives passing through the turnout. The starting position of the turnout speed limit of the train receiving unit is at the shortest position from different routes to the turnout.

[0077] The turnout speed limit value of the train departure unit is the lowest value of the turnout speed limit for all locomotives passing through the turnout. The position of the termination speed limit of the turnout speed limit of the train departure unit is at the farthest position from the turnout to different routes.

[0078] The new route data also includes transfer information. The generation of the transfer information includes the following steps:

[0079] Step J1): Read the signal information of the line in sequence.

[0080] Step J2): Determine whether the same signal is on different lines. If so, mark the position where the signal is located as a divergence point. If not, do not mark the divergence point. The transfer information is, after the line is made, based on the divergence point information, adding branch transfer and label data to the line data to describe the marked divergence point.

[0081] Step J3): Add branch transfers and corresponding labels at different divergence points respectively.

[0082] The present invention discloses a method for automatically generating LKJ-15 data. It can summarize the existing railway station scenarios for LKJ-15 type equipment and data, use the data such as the line facilities and transportation reported by the railway administration as source data to generate LKJ-15 basic data. While ensuring the correctness of the data, it also ensures the consistency of the data, and reduces the manual participation in the process of compiling LKJ-15 data, saves labor costs, and improves work efficiency.
