Description

Technical Field

[0001] This invention relates to the field of CTC system technology, and specifically to a method for identifying and controlling the rendezvous and collision prevention between high-speed trains and freight trains based on CTC operation diagrams. Background Technology

[0002] With the continuous expansion of my country's railway network, the demand for railway transportation is becoming increasingly diversified, and the passenger-freight co-operation mode still occupies an important position on some lines. China State Railway Group Co., Ltd. (China Railway) has announced relevant matters during quarterly adjustments to train timetables: On conventional speed lines (excluding hubs), in principle, EMU trains (excluding inspection cars, confirmation cars, and returned empty wagons) will not be operated. If such operation is necessary, EMU trains and freight cars will not meet on the same section. On lines designed for passenger (EMU) and freight co-operation, where EMU trains operate at a maximum speed of 160 km / h, and on lines that have been adapted to operate EMU trains with the approval of China Railway, EMU trains and freight cars will not meet on the same section. Express freight trains and container trains (excluding open-top containers) may meet with EMU trains on the same section. Existing technology uses a method to check for planned conflicts between oversized and overweight vehicles that prohibit them from meeting on the same section. Oversized vehicles are identified by the train line alignment, and the planned conflicts between oversized and overweight vehicles that prohibit them from meeting on the same section are checked. However, identifying oversized vehicles solely based on train line alignment lacks flexibility for practical application; furthermore, it does not consider whether two trains that are prohibited from passing each other in a section are actually operating on adjacent sections where passing is prohibited. Summary of the Invention

[0003] The purpose of this invention is to provide a method for identifying and controlling the no-passing restrictions between EMUs and freight cars based on the CTC timetable. Specifically, it includes a method for flexibly configuring the range of train numbers for EMUs and freight cars that are prohibited from passing between sections, solving the problem of identifying the no-passing attributes between adjacent lines and train operating lines based on the CTC timetable. Furthermore, it proposes a method for identifying and controlling the no-passing restrictions between EMUs and freight cars based on the CTC timetable to adapt to the flexible and ever-changing transportation needs of actual scheduling and production, and to ensure the safe operation of railway trains.

[0004] The first aspect of the present invention is to provide a method for identifying and controlling the no-passing restrictions between high-speed trains and freight trains based on a CTC (Continuous Traffic Control) timetable, comprising:

[0005] S1, based on the CTC operation diagram, identifies the no-passing rule between EMU and freight trains on the train operation line;

[0006] S2, based on the CTC timetable, implements the restriction and control of EMU and freight trains on the train operation line, including: providing flexible alarm prompts and control for conflict plans containing the restriction and control at the planning level at the CTC timetable terminal; and issuing phase plans to send the restriction and control information to the CTC station self-regulator, which then performs further control at the execution level.

[0007] Preferably, S1 includes:

[0008] S11, Input the two train lines to be identified. Based on the EMU and freight train section no-passing attribute values ​​of the two train lines, confirm whether the two train lines are in the EMU and freight train section no-passing relationship. If not, then the two train lines do not have section no-passing; if so, continue to S12 for identification.

[0009] S12, determine whether there is a section where the two train lines operate simultaneously; if the following two conditions are met simultaneously, continue to S13 for identification; if the following two conditions are not met simultaneously, then there is no section where the two train lines are prohibited from passing each other; the two conditions include equation (1) and equation (2):

[0010]

[0011] in Indicates train operating line l j At the beginning of Indicates train operating line l j At the end of the day, Indicates train operating line l j At the beginning of Indicates train operating line l j The end time; Indicates train operating line l j The arrival time of entering section s, Indicates train operating line l j At the departure time from section s, Indicates train operating line l j The arrival time of entering section s, Indicates train operating line l j The departure time from section s;

[0012] S13, determine whether the two train lines are traveling towards each other within section s. If they are traveling towards each other, continue with S14 for identification. If they are not traveling towards each other, then the two train lines do not have a section no-passing rule.

[0013] S14, determine whether the two train lines operate within section s in adjacent section line groups that consider the no-passing rule for EMU and freight trains, i.e., determine whether the line groups of these two train lines within section s exist. Within the configuration, if such a configuration exists, the two train lines are prohibited from meeting in section s; if it does not exist, then these two train lines are not prohibited from meeting in section s. The configuration format for adjacent lines in the interval that are configured to be prohibited from meeting is as follows, where s pIndicates the range ID; and Indicates the interval ID is s p Within the interval, consider the IDs of two adjacent lines where trains are prohibited from passing.

[0014] Preferably, S2 includes:

[0015] S21, by setting a flexible control configuration for the inter-station and freight train crossing restrictions in the CTC operation diagram terminal, the conflict plans containing inter-station crossing restrictions are flexibly alarmed and controlled from the planning level; wherein the configuration value of the flexible control configuration for the inter-station and freight train crossing restrictions has four configurations to meet the train operation command and dispatch needs of different railway bureau group companies in different dispatch sections.

[0016] When the configuration value is 0, it means that the planned conflict of the section prohibition between EMU and freight trains is not checked;

[0017] When the configuration value is 1, it indicates that the plan conflict between the EMU and the freight train is checked for the section meeting restriction. However, such a plan conflict can be ignored with one click and a phase plan can be issued.

[0018] When the configuration value is 2, it indicates that the plan conflict between the EMU and the freight train is checked. However, such a plan conflict cannot be ignored and a phase plan can be issued. Each such plan conflict alarm must be confirmed before a phase plan can be issued.

[0019] When the configuration value is 3, it means that the plan conflict of the section refusal between EMU and freight train is checked, and the issuance of the phase plan containing such plan conflict is strictly controlled. The train operation lines involved in such plan conflict need to be adjusted one by one until there is no section refusal plan conflict before the phase plan can be issued.

[0020] S22, the CTC timetable terminal adds the section refusal information to the phase plan issued to the CTC station autonomous machine. The section refusal information includes whether it is a high-speed train in the section refusal relationship between high-speed trains and freight trains, and whether it is a freight train in the section refusal relationship between high-speed trains and freight trains. The CTC timetable terminal issues the phase plan containing the section refusal information to the CTC station autonomous machine, and the CTC station autonomous machine further controls the section refusal conflict scenario between high-speed trains and freight trains at the execution level.

[0021] Preferably, the method for determining the no-passing attribute value between the EMU and freight trains on the two train operating lines in S11 includes:

[0027] (2) Configure the rules for prohibiting trains from passing each other within a section, wherein the configuration format of the rules for prohibiting trains from passing each other within a section is as follows:

[0028] C1={n i n i+1 …};

[0029] C2 = 0|1;

[0030] C3={n j n j+1 …};

[0031] C4 = 0|1;

[0032] Wherein, C1 represents the configuration of the EMU train number range in the no-passing relationship between EMU and freight train, which consists of the set of train number range IDs corresponding to the configuration of the train number range;

[0033] C2 indicates whether the train number range in the no-passing relationship between EMUs and freight trains is configured to allow or prohibit EMUs from passing each other. C2=0 means that C1 is configured to allow the train number range in the no-passing relationship between EMUs and freight trains, and C2=1 means that C1 is configured to allow the train number range in the no-passing relationship between EMUs and freight trains.

[0034] C3 represents the configuration of freight train number range in the no-passing relationship between EMU and freight train, which consists of the set of train number range IDs corresponding to the configuration of the train number range;

[0035] C4 indicates whether the range of freight train numbers configured in the no-passing relationship between EMU and freight trains is for freight trains that are prohibited from passing or allowed to pass. C4=0 indicates that C3 is configured with the range of freight train numbers for which freight trains are prohibited from passing in the no-passing relationship between EMU and freight trains, while C4=1 indicates that C3 is configured with the range of freight train numbers for which freight trains are allowed to pass in the no-passing relationship between EMU and freight trains.

[0036] Preferably, the identification of train passing restrictions in sections based on the CTC timetable includes:

[0037] (1) Add an attribute value F to the train operation line for the prohibition of passing between EMU and freight trains. F is a positive integer. The 0th bit F0 of the attribute value F indicates whether the train operation line is a EMU in the prohibition relationship. When F0 = 0, it means that the train operation line is not a EMU in the prohibition relationship between EMU and freight trains. When F0 = 1, it means that the train operation line is a EMU in the prohibition relationship between EMU and freight trains. The 1st bit F1 of the attribute value F indicates whether the train operation line is a freight train in the prohibition relationship. When F1 = 0, it means that the train operation line is not a freight train in the prohibition relationship between EMU and freight trains. When F1 = 1, it means that the train operation line is a freight train in the prohibition relationship between EMU and freight trains.

[0038] (2) Identify the attribute value F of the train operation line where EMU trains and freight cars are prohibited from meeting.

[0039] Preferably, the identification of the attribute value F for the no-passing rule between EMU trains and freight trains on the train operating line includes:

[0048] Step 3: Determine whether the train operating line l is a freight train in the section where EMU and freight trains are prohibited from passing each other;

[0049] If the train line is for freight trains:

[0050] When C4 = 0 and l ∈ C3, F1 = 1;
