Description

Technical Field

[0001] The present invention relates to the technical field of train operation risk identification, and particularly relates to a method and system for identifying and preventing the risk of passing trains meeting at stations, so as to realize a method for identifying and protecting the risk of passing trains meeting at stations based on the CTC system. Background Art

[0002] The Centralized Traffic Control (CTC) system monitors the signal equipment and train operation conditions within its jurisdiction, optimizes the train operation plan, coordinates train and shunting operations, strictly controls the arrangement of station approaches according to the train plan, and ensures the efficiency and safety of railway transportation. It is an important part of high-end railway equipment manufacturing. Its main functions include train position tracking, in-station approach control, fault detection and handling. Specifically:

[0003] (1) Train position tracking: The CTC system obtains the train number through technical means such as the G network / 450M wireless train number information or manual confirmation, and monitors and tracks the train operation status through track circuit acquisition information or section train control indication information, and real-time feedbacks it to the station yard display interface of the system, facilitating relevant staff to understand the train operation situation, and at the same time providing basic data for the decentralized self-discipline control of the system.

[0004] (2) In-station approach control: The CTC system adopts the station decentralized self-discipline mode. Based on the train operation adjustment plan, it sends control commands to the interlocking system to realize the automatic control of the in-station train approach arrangement, specifically manifested as the opening and closing of in-station approach signal lights, the locking and clearing of approaches, the setting and reverse position operation of approach turnout objects, and the alarm when the approach conditions are not met, etc.

[0005] (3) Fault detection and handling: The CTC system monitors the train and signal equipment conditions, can automatically analyze and identify faults and timely send message prompts. The CTC system has established a complete and reliable communication system to realize information interaction between the center and stations, between stations, and between stations and trains. In this way, after detecting a fault, the fault information can be accurately pushed to the electric maintenance equipment.

[0006] When double-track trains meet and run between railway stations, considering factors such as the shortest distance between the double tracks, the train body width, and the train running speed, there may be risks of emergency braking or even collision of trains. Therefore, for two specific types (different body widths) or two trains of the same type, it is required to prohibit meeting at stations. The identification and prevention and control of the risk of passing trains meeting at stations have always been one of the key issues of railway operation safety and a special work content that needs to be improved urgently. Currently, the prevention means for passing trains meeting at stations include:

[0007] (1) Initially, the preventive measure for preventing passing of non - passing trains between stations was to manually identify risks. When handling the inter - station block, the receiving station would prompt the adjacent departure station to prohibit departure, and the duty officer at the departure station would control the arrangement of the departure route corresponding to the port to prevent non - passing trains from entering the section. However, with the increase in railway passenger and freight transport services and the improvement of locomotive operating speeds, manually identifying such risks can no longer meet the actual needs in terms of both accuracy and timeliness.

[0008] (2) The CTC system reduces the risk of passing of non - passing trains between stations to a certain extent. It identifies the train type through the train number of the trains running in the section and automatically controls the route arrangement of the departure ports on the adjacent line according to the established non - passing rules to ensure that another non - passing train type will not enter the section. However, the problems of this technology mainly include: on the one hand, the corresponding relationship between the train number and the train type may be updated and changed, unable to guarantee the accuracy of judging the train type; on the other hand, this method is only effective for the situation where one train has already entered the section. If the departure route has been arranged at the adjacent station but the train has not yet entered the section, it cannot effectively control.

[0009] Therefore, there is a need to design a new method and system for identifying and preventing the risk of passing of non - passing trains between stations. Summary of the Invention

[0010] The purpose of the present invention is to provide a method and system for identifying and preventing the risk of passing of non - passing trains between stations. The corresponding technical means are mainly used to solve the following technical problems:

[0011] (1) Design a method for obtaining the adjacent line port plan to achieve the function of preventing the risk of passing of non - passing trains between stations;

[0012] (2) Design a method for identifying the types of trains running on the adjacent line to achieve the function of preventing the risk of passing of non - passing trains between stations;

[0013] (3) A prevention and control plan for the risk of head - on passing of non - passing trains between stations based on the CTC system;

[0014] (4) A prevention and control plan for the risk of passing in the same direction of non - passing trains between stations based on the CTC system;

[0015] (5) A prevention and control plan for the risk of passing of non - passing trains on multiple lines based on the CTC system.

[0016] The first aspect of the present invention lies in providing a method for identifying and preventing the risk of passing of non - passing trains between stations, including:

[0017] S1, identifying the key information of the risk of passing of non - passing trains between stations for formulating the corresponding risk identification and prevention and control plan. The key information of the risk of passing of non - passing trains between stations includes the adjacent line ports between stations, the port plans of adjacent stations on the adjacent line, and the types of trains running on the adjacent line;

[0018] S2. Based on the key information of the passing risk between non - passing train stations and the types of passing scenarios between train stations, determine the corresponding passing risk identification and prevention and control plans. Among them, the types of passing scenarios between train stations include head - on passing, same - direction passing, and multi - line passing. The passing risk identification and prevention and control plans include the head - on passing risk identification and prevention and control plan between non - passing train stations, the same - direction passing risk identification and prevention and control plan between non - passing train stations, and the multi - line passing risk identification and prevention and control plan for non - passing trains.

[0019] Preferably, S1 includes:

[0020] S11. Identify the adjacent line ports between stations, including: identifying the local port of the adjacent line and the adjacent - station port of the adjacent line. The adjacent line refers to the two inter - station lines in the up - and - down directions between two stations;

[0021] S12. Obtain the plans of the adjacent - station ports of the adjacent line, including the receiving - train port plan and the departing - train port plan; the plans of the adjacent - station ports of the adjacent line include information such as train number, train type, plan type, planned time, and plan status. The plans under the same port will be arranged in the order of the planned time. The plan type includes receiving train, departing train, or passing through; the plan status includes waiting, arranged successfully, or occupied;

[0022] S13. Identify the types of trains running on the adjacent line.

[0023] Preferably, S11 includes: Based on the basic data of the CTC system, identify the adjacent line ports between stations of any port, including:

[0024] (1) Set a unique line ID for the inter - station line based on the basic data of the CTC system, including the line ID where it is located and the adjacent - line ID;

[0025] (2) Identify the target port attributes, where the target port attributes include the line ID where it is located, the local station code of the target port, and the corresponding adjacent - station code; the line ID where it is located is A, the local station code of the target port is B, and the corresponding adjacent - station code is C;

[0026] (3) Determine the adjacent - line ID of any line through a predetermined rule. The adjacent - line ID is A1, and the predetermined rule is: The inter - station lines with line IDs A and A1 are adjacent lines to each other;

[0027] (4) Based on the adjacent - line port identification logic between stations and the identified adjacent line after judgment, identify the ports of this line, and finally identify the adjacent line ports.

[0028] Preferably, the step of identifying the ports of this line based on the adjacent - line port identification logic between stations and the identified adjacent line after judgment, and finally identifying the adjacent line ports includes:

[0029] Traverse and search for the local station port and the adjacent station port simultaneously. The local station code is B, and the adjacent station code is C.

[0030] For traversing and searching for the local station port, determine whether the line ID is A1. If it is, then determine whether the adjacent station code is C. If not, return to the starting end. If the adjacent station code is C, find the local station port of the adjacent line, mark it, and then end. If not, return to the starting end.

[0031] For traversing and searching for the adjacent station port, determine whether the line ID is A1. If it is, then determine whether the adjacent station code is B. If not, return to the starting end. If the adjacent station code is C, find the adjacent station port of the adjacent line, mark it, and then end. If not, return to the starting end.

[0032] Preferably, the S12 includes:

[0033] (1) Identify the target port attribute and find the adjacent station code X.

[0034] (2) The adjacent station port actively sends its own port plan information. The sending of the port false information adopts the form of "real-time + periodic", that is, when the port plan changes, it is immediately sent externally, and at the same time, it is sent externally regularly at a fixed period, that is, the current plan of the port at the current moment. When the port plan changes and is immediately sent externally, it includes: monitoring the target port plan. If the target port plan changes, it is immediately sent to the adjacent station. The changes include one or more of the port plan status change, port plan attribute change, and port plan quantity change. The sending of the current plan of the port at the current moment regularly at a fixed period includes: obtaining the current plan time of this port, determining whether the fixed sending period is reached. If it is reached, it is sent to the adjacent station. If not, it loops to monitor whether the fixed sending period is reached.

[0035] (3) The local decentralized self-discipline subsystem screens, processes, and caches the port plan information of itself.

[0036] Preferably, the S13 includes:

[0037] (1) Obtain the train running direction and the train number. Among them, obtaining the train running direction includes: referring to the interval direction light outside the adjacent line port, that is, the train running direction in this interval is completely consistent with the direction indicated by the interval direction light. Obtaining the train number includes: by monitoring the adjacent line interval object, if its state is judged to be occupied, find the associated train number window object and obtain the train number information in it as the train number.

[0038] (2)Identify the types of trains running on adjacent lines based on the obtained train running direction and train number, including: after obtaining the running direction and train number of the train running in the section, first find the receiving port of the station ahead of the train through the train running direction, then find the plan with the same train number at this port through the train number of the running train, and then identify the type of the train through the plan attributes.

[0039] Preferably, the S2 includes:

[0040] S21. Determine the risk identification and prevention and control plan for head-on passing of restricted passing trains between stations based on the key information of the risk of head-on passing of restricted passing trains between stations and the train head-on passing scenario between stations;

[0041] The risk identification and prevention and control plan for head-on passing of restricted passing trains between stations includes:

[0042] When the train instruction at the target departure port reaches the trigger timing for route arrangement, check the receiving and departure directions of the port of this station on the adjacent line. If the direction is receiving, it is determined that the trains are running head-on between stations;

[0043] Check the types of trains running in the section. According to the established rules, judge whether the types of trains departing from the station and the trains running in the section meet the requirements of restricted passing. If they meet, it is considered that there is a conflict. At this time, suspend arranging the corresponding departure route, give an alarm prompt and continuously monitor. If the conflicting train enters the station of this station, it is considered that the conflict is eliminated;

[0044] If it is monitored that there is no conflict with the type of the train running in the section or the conflict is eliminated, then analyze all the departure plans of the adjacent station ports on the adjacent line in turn, and find the plans with conflicting train types with the train type at the target port. If there is no plan that meets the conditions, the check passes and it is determined that there is no risk of passing between stations;

[0045] If a plan with a conflicting train type is found and the status of this plan is arranged successfully or occupied, then suspend arranging the departure route of the target port, give an alarm prompt and continuously monitor. If the conflicting train enters the station of this station, it is considered that the conflict is eliminated;

[0046] If the status of the conflicting plan is waiting and the plan time is earlier than the departure plan time of the target port, also suspend arranging the departure route of the target port, give an alarm prompt and continuously monitor. If the conflicting train leaves the adjacent station and enters this station, it is considered that the conflict is eliminated;

[0047] If the status of the conflicting plan is waiting and the plan time is later than or equal to the departure plan time of the target port, then the check passes and it is considered that there is no risk of passing between stations;

[0048] Perform variable inspection on the above conflict content to ensure that the same conflict will not be alarmed repeatedly;

[0049] S22. Based on the key information of the no-meeting risk between stations of the prohibited trains and the scenario of train meeting between stations being in the same direction, determine the risk identification and prevention and control plan for the same-direction meeting between stations of the prohibited trains;

[0050] The risk identification and prevention and control plan for the same-direction meeting between stations of the prohibited trains includes:

[0051] When the train instruction at the target departure port reaches the trigger timing for route arrangement, check the receiving and departure directions of the adjacent line's own station port. If the direction is departure, it is determined that the trains are running in the same direction between stations;

[0052] Check the types and maximum speeds of the trains running in the section. First, according to the established rules, judge whether the types of the trains departing from the station and the trains running in the section require no meeting. If no meeting is required, further confirm whether the maximum speed of the train at the target port is greater than the speed of the no-meeting train type in the section. If both of the above two conditions are met, it is considered that there is a meeting risk and a conflict exists. Suspend arranging the departure route of the port and give an alarm prompt and continuously monitor. If the conflicting train enters the adjacent station, it is considered that the conflict is eliminated;

[0053] If it is monitored that there is no conflict with the type of the train running in the section or the conflict is eliminated, then analyze all the departure plans of the adjacent line's own station port in turn, and find the plans whose train types conflict with the train type at the target port. If there is no plan that meets the conditions, the inspection passes and it is determined that there is no meeting risk between stations and no conflict exists;

[0054] If a plan with a train type conflict is found and the status of the plan is arranged successfully or occupied, suspend arranging the departure route of the target port and give an alarm prompt and continuously monitor. If the conflicting train enters the adjacent station, it is considered that the conflict is eliminated;

[0055] If the status of the conflicting plan is waiting and the plan time is earlier than the departure plan time of the target port, also suspend arranging the departure route of the target port and give an alarm prompt and continuously monitor. If the conflicting train leaves this station and enters the adjacent station, it is considered that the conflict is eliminated;

[0056] If the status of the conflicting plan is waiting and the plan time is later than or equal to the departure plan time of the target port, the inspection passes and it is considered that there is no meeting risk between stations;

[0057] Perform variable inspection on the above-mentioned conflict content to ensure that the same conflict will not be alarmed repeatedly;

[0058] S23. Based on the key information of the no-meeting risk between stations of the prohibited trains and the scenario of train meeting between stations being multi-line meeting, determine the risk identification and prevention and control plan for the multi-line meeting of the prohibited trains;

[0059] The risk identification and prevention and control plan for the multi-line meeting of the prohibited trains includes:

[0060] When the train instruction of the target departure port reaches the timing to trigger route arrangement, obtain the adjacent line objects and their quantities, judge the running direction of the train on the first adjacent line. If it is determined to be a risk of face-to-face meeting between stations, call the risk judgment logic for face-to-face meeting between stations of restricted meeting trains to execute prevention and control;

[0061] If it is determined to be a risk of same-direction meeting between stations, call the risk judgment logic for same-direction meeting between stations of restricted meeting trains to execute prevention and control;

[0062] When it is judged that there is a risk of meeting between stations with the first adjacent line, give an alarm prompt and continuously monitor until the conflict is eliminated;

[0063] If it is judged that there is no risk of meeting between stations with the first adjacent line or the conflict is eliminated, then continue to judge the risk of meeting with the second adjacent line;

[0064] And so on until it is judged that there is no risk of meeting with all adjacent lines, then execute the route arrangement for the target departure port.

[0065] The second aspect of the present invention lies in providing a system for identifying and preventing and controlling the risk of meeting between stations of restricted meeting trains, which is used to implement the method of the first aspect, including:

[0066] The key information identification module (101) is used to identify the key information of the risk of meeting between stations of restricted meeting trains for formulating corresponding risk identification and prevention and control plans. The key information of the risk of meeting between stations of restricted meeting trains includes the ports of adjacent lines between stations, the planned ports of adjacent stations of adjacent lines, and the types of trains running on adjacent lines;

[0067] The risk identification and prevention and control plan determination module (102) is used to determine the corresponding risk identification and prevention and control plan based on the key information of the risk of meeting between stations of restricted meeting trains and the types of meeting scenarios between stations of trains. Among them, the types of meeting scenarios between stations of trains include face-to-face meeting, same-direction meeting, and multi-line meeting. The risk identification and prevention and control plan includes the risk identification and prevention and control plan for face-to-face meeting between stations of restricted meeting trains, the risk identification and prevention and control plan for same-direction meeting between stations of restricted meeting trains, and the risk identification and prevention and control plan for multi-line meeting between stations of restricted meeting trains.

[0068] The third aspect of the present invention provides an electronic device, including a processor and a memory. The memory stores multiple instructions, and the processor is used to read the instructions and execute the method described in the first aspect.

[0069] The fourth aspect of the present invention provides a computer-readable storage medium, which stores multiple instructions, and the multiple instructions can be read and executed by the processor to execute the method described in the first aspect.

[0070] The beneficial effects of the method and system of the present invention:

[0071] This prevention and control plan aims to identify the risks of passing trains meeting at stations earlier and more accurately. It blocks the risks of passing trains meeting at stations at the level of the railway signal control system, reduces the labor intensity of train dispatchers, and plays an active and effective role in aspects such as ensuring safety through technical means and improving lean and efficient command capabilities. At the same time, without changing the CTC system structure, it expands the system's extension direction, enriches the system functions, and provides new ideas for the safe and intelligent development of the CTC system. The main manifestations are as follows:

[0072] (1)Under the framework of the existing CTC system, deeply excavate and analyze the existing system data, establish new logical relationships, identify the possible risks of passing trains meeting at stations, and then formulate effective and feasible prevention and control plans to prevent the occurrence of such risks.

[0073] (2)According to the running direction of trains between stations, the layout of lines between stations and their associated relationships, analyze all possible scenarios of trains meeting between stations, and formulate corresponding prevention and control plans for passing trains in combination with different scenarios.

[0074] (3)Expand the monitoring scope in terms of both time and space scales to achieve earlier and more accurate risk identification. In terms of time, take into account the planned times of all trains on adjacent lines, strictly release trains into the section according to the sequence of planned times, and prevent the situation of passing trains meeting at stations caused by not following the planned times. In terms of space, in addition to monitoring trains running in the section, expand the monitoring of train departures at stations to prevent the situation of releasing passing trains to a double-track section simultaneously from two adjacent stations.

[0093] See Figure 1 , the first aspect of the present invention is to provide a method for identifying and preventing the risk of passing trains meeting at stations, including:

[0094] S1, identifying the key information of the risk of passing trains meeting at stations for formulating the corresponding risk identification and prevention plan. The key information of the risk of passing trains meeting at stations includes the adjacent line ports between stations, the planned ports of adjacent lines at adjacent stations, and the types of trains running on adjacent lines. The key information of the risk of passing trains meeting at stations is the key factor for judging the risk of passing trains meeting at stations, and the corresponding risk identification and prevention plan can be formulated only through the excavation and analysis of the above information.

[0095] As Figure 2 shown, as a preferred implementation manner, the S1 includes:

[0096] S11, identifying the adjacent line ports between stations, including: identifying the local port of the adjacent line and the port of the adjacent station of the adjacent line. The adjacent line is two inter-station lines in the up and down directions between two stations;

[0097] As Figure 3 shown, in this embodiment, for any port, the port connected by the adjacent line of the line where it is located is the adjacent line port between stations, which can be subdivided into the local port of the adjacent line and the port of the adjacent station of the adjacent line. As Figure 1 , there are two inter-station lines in the up and down directions between stations A and B, and these two lines are adjacent to each other. Taking port X of station A as an example, its local port of the adjacent line is port XN of station A, and the port of the adjacent station of the adjacent line is port S of station B.

[0098] See also Figure 4 , as a preferred implementation, the S11 includes: identifying the inter-station adjacent line port of any port based on the basic data of the CTC system, including:

[0099] (1) First, a unique line ID is set for the inter-station line based on the basic data of the CTC system, including the line ID and the adjacent line ID;

[0100] (2) Identify the target port attributes, which include the line ID (A) to which it belongs, the station code (B) to which the target port belongs, and the corresponding neighbor station code (C);

[0101] (3) Determine the adjacent line ID (A1) of any line by a predetermined rule, wherein the predetermined rule is: the inter-station lines with line IDs A and A1 are adjacent lines to each other;

[0102] (4) Based on the inter-station adjacent line port identification logic and the determined adjacent line, the port of the line is identified, and finally the adjacent line port is identified, including:

[0103] Simultaneously search for the local port and the neighboring port. The local code is B and the neighboring code is C;

[0104] For traversal to find the local port, determine whether the line ID is A1. If so, determine whether the neighboring station code is C. If not, return to the starting end; if the neighboring station code is C, find the local port of the adjacent line and mark it before ending. If not, return to the starting end;

[0105] For traversal to find the neighboring station port, determine whether the line ID is A1. If so, determine whether the neighboring station code is B. If not, return to the starting end; if the neighboring station code is C, find the neighboring station port of the adjacent line and mark it before ending. If not, return to the starting end.

[0106] S12, obtain the adjacent line adjacent station port plan, including the pick-up port plan and the departure port plan; the adjacent line adjacent station port plan includes the train number, train type, plan type (pick-up, departure, passing), plan time and plan status (including waiting, successful arrangement, occupied, etc.), etc. The plans under the same port will be arranged in the order of plan time.

[0107] The decentralized and autonomous execution of the CTC system's stage plan is implemented with the port as the smallest unit, that is, after receiving the central stage plan, the plan is split into one receiving and one sending, corresponding to the receiving port plan and the sending port plan respectively; the CTC station decentralized autonomous subsystem can directly obtain all the port plans of this station, so there is no need to obtain the port plans of the adjacent lines in advance, and they can be directly captured when risk identification and judgment are made.

[0108] See Figure 5 , as a preferred embodiment, S12 includes:

[0109] (1) Identify the target port attribute and find the adjacent station code X;

[0110] (2) The adjacent station port actively sends its own port plan information; the port plan information is sent in the form of "real-time + periodic", that is, when the port plan changes, it is immediately sent externally, and at the same time, it is regularly sent externally at a fixed period for the current plan of this port at the current moment; when the port plan changes and is immediately sent externally, it includes: monitoring the target port plan, if the target port plan changes, it is immediately sent to the adjacent station, and the changes include one or more of the port plan status change, port plan attribute change, and port plan quantity change; regularly sending the current plan of this port at the current moment externally at a fixed period includes: obtaining the current plan time of this port, determining whether the fixed sending period is reached, if it is reached, it is sent to the adjacent station, and if not, it loops to monitor whether the fixed sending period is reached.

[0111] (3) The decentralized autonomous subsystem of this station screens, processes, and caches the port plan information of itself.

[0112] S13, identify the types of trains running on the adjacent line, including:

[0113] (1) Obtain the train running direction and train number. Among them, obtaining the train running direction includes: referring to the interval direction light outside the adjacent line port, that is, the train running direction in this interval is completely consistent with the direction indicated by the interval direction light; obtaining the train number includes: by monitoring the adjacent line interval object, if its status is determined to be occupied, find the associated train number window object and obtain the train number information therein as the train number.

[0114] See Figure 6, in this embodiment, the specific implementation details include: monitoring whether the receiving and dispatching directions of the ports of the adjacent line's own station are lit. If lit, set the parameter Dir = 1; otherwise, set the parameter Dir = 2. Monitor the Mth section object (M = 1, the total number is N) of the adjacent line to determine whether it is in the occupied state. If it is not in the occupied state, determine whether M is greater than or equal to N. If so, reset the parameter Dir = 0 and end; otherwise, M += 1. If it is in the occupied state, find its associated train schedule window and obtain the train number, and determine whether Dir = 1 is satisfied. If Dir = 1, obtain the plan of the adjacent line's adjacent station port, find the plan with the same train number and obtain the train type, and then determine whether M is greater than or equal to N. If so, reset the parameter Dir = 0 and end; otherwise, M += 1. If Dir = 1 is not satisfied, continue to determine whether Dir = 2 is satisfied. If Dir = 2 is satisfied, obtain the plan of the adjacent line's own station port, find the plan with the same train number and obtain the train type. If Dir = 2 is not satisfied, alarm to indicate that the port direction is abnormal and end.

[0115] (2) Identify the types of trains running on the adjacent line based on the obtained train running direction and train number, including: after obtaining the running direction and train number of the train running in the section, first find the receiving port of the station in front of the train through the train running direction, then find the plan with the same train number at this port through the train number of the running train, and further identify the type of the train through the plan attributes.

[0116] S2. Determine the corresponding intersection risk identification and prevention and control plan based on the key information of the intersection risk between non - meeting trains at stations and the types of train station - to - station intersection scenarios. Among them, the types of train station - to - station intersection scenarios include head - on intersection, same - direction intersection, and multi - line intersection. The intersection risk identification and prevention and control plan includes the head - on intersection risk identification and prevention and control plan between non - meeting trains at stations, the same - direction intersection risk identification and prevention and control plan between non - meeting trains at stations, and the multi - line intersection risk identification and prevention and control plan for non - meeting trains.

[0117] As Figure 7 shown, as a preferred implementation method, S2 includes:

[0118] S21. Determine the head - on intersection risk identification and prevention and control plan between non - meeting trains at stations based on the key information of the intersection risk between non - meeting trains at stations and the head - on intersection of the train station - to - station intersection scenario;

[0119] As Figure 8 shown in the schematic diagram of head - on intersection between trains at stations, when the running directions of trains on adjacent lines are inconsistent, the intersection between trains at stations is defined as head - on intersection.

[0120] As Figure 9 shown, the head - on intersection risk identification and prevention and control plan between non - meeting trains at stations includes:

[0121] When the train instruction of the target departure port reaches the triggering time, check the receiving and dispatching direction of the adjacent line's station port. If the direction is to receive the train, it is determined that the trains are running in opposite directions between stations;

[0122] Check the type of trains running in the section, and determine whether the types of trains departing from the station and running in the section meet the prohibition requirements according to the established rules. If they do, it is considered that there is a conflict. At this time, the corresponding departure route is suspended, and an alarm is issued and continuous monitoring is carried out. If the conflicting train enters the station, the conflict is considered to be eliminated;

[0123] If it is detected that there is no conflict with the train type in the interval or the conflict is eliminated, all departure plans of adjacent lines and adjacent stations will be analyzed in turn to find plans whose train types conflict with the train types of the target port. If there is no plan that meets the conditions, the check is passed and it is determined that there is no risk of crossing between stations;

[0124] If a plan with conflicting train types is found, and the plan status is successfully arranged or occupied, the arrangement of the departure route of the target port will be suspended, and an alarm will be issued and continuous monitoring will be carried out. If the conflicting train enters the station, the conflict is considered to be resolved;

[0125] If the conflicting plan status is waiting and the planned time is earlier than the target port departure plan time, the target port departure route will also be suspended, and an alarm will be issued and continuous monitoring will be carried out. If the conflicting train leaves the adjacent station and enters this station, the conflict is considered to be resolved;

[0126] If the conflicting plan status is waiting and the planned time is later than or equal to the target port departure plan time, the check passes and it is considered that there is no risk of inter-station intersection;

[0127] Perform a change check on the above conflict contents to ensure that the same conflict will not cause repeated alarms.

[0128] S22, based on the key information of the forbidden train crossing risk between stations and the train crossing scenario, determining the forbidden train crossing risk identification and prevention plan for the same-direction crossing between stations;

[0129] If Figure 10 As shown in the diagram of train stations crossing in the same direction, when the trains on adjacent lines run in the same direction, the train crossing between stations is defined as crossing in the same direction. The crossing risk identification in this scenario requires an additional necessary judgment condition: the maximum speed of the rear vehicle is greater than that of the front vehicle.

[0130] If Figure 11 As shown in the figure, the risk identification and prevention plan for the forbidden trains crossing in the same direction between stations includes:

[0131] The train instruction of the target departure port reaches the triggering time of route arrangement, and the receiving and departure direction of the station port of the adjacent line is checked. If the direction is departure, it is determined that the trains are running in the same direction between stations; ​

[0132] Check the types and maximum speeds of trains running in the section. First, determine whether the types of trains departing from the station and trains running in the section require non-meeting according to the established rules. If non-meeting is required, further confirm whether the maximum speed of the train at the target port is greater than the speed of the non-meeting train type in the section. If both of the above two conditions are met, it is considered that there is a risk of meeting and a conflict exists. Suspend arranging the departure route of the port and give an alarm prompt and continuously monitor. If the conflicting train enters the adjacent station, it is considered that the conflict is eliminated;

[0133] If it is monitored that there is no conflict with the type of train running in the section or the conflict is eliminated, analyze all departure plans of the local port on the adjacent line in turn, and find the plans in which the train type conflicts with the train type at the target port. If there is no plan that meets the conditions, the inspection passes and it is determined that there is no risk of meeting between stations and no conflict exists;

[0134] If a plan with a train type conflict is found and the status of the plan is arranged successfully or occupied, suspend arranging the departure route of the target port and give an alarm prompt and continuously monitor. If the conflicting train enters the adjacent station, it is considered that the conflict is eliminated;

[0135] If the status of the conflicting plan is waiting and the planned time is earlier than the departure plan time of the target port, also suspend arranging the departure route of the target port and give an alarm prompt and continuously monitor. If the conflicting train leaves this station and enters the adjacent station, it is considered that the conflict is eliminated;

[0136] If the status of the conflicting plan is waiting and the planned time is later than or equal to the departure plan time of the target port, the inspection passes and it is considered that there is no risk of meeting between stations;

[0137] Perform variable inspection on the above-mentioned conflict content to ensure that the same conflict will not be alarmed repeatedly.

[0138] S23. Determine the risk identification and prevention and control plan for multi-line meeting of prohibited meeting trains based on the key information of the risk of meeting between stations of prohibited meeting trains and the scenario of meeting between stations of trains being multi-line meeting;

[0139] Such as Figure 12As shown in the schematic diagram of multiple adjacent lines, in actual situations, there is a special type of adjacent relationship between intervals, that is, a section line has two adjacent lines simultaneously. Section line 1 is adjacent to section line 2 and section line 3 respectively. When dispatching trains to section line 1 and identifying the risk of non - meeting between stations, it is necessary to consider the train operation conditions of section lines 2 and 3 as well as the train dispatching plans for these two sections simultaneously. Taking the SN port of station B in the figure as the target departure port, identify the non - meeting risk between line 1 and line 2. Regard the S port of station C as the local port of the adjacent line, and the XN port of station A as the adjacent - station port of the adjacent line. At the same time, monitor the train arrival and departure direction of the S port of station C. Similarly, to identify the non - meeting risk between line 1 and line 3, it is necessary to regard the S port of station B as the local port of the adjacent line, and the XN port of station C as the adjacent - station port of the adjacent line, and monitor the train arrival and departure direction of the S port of station C at the same time. Only when no non - meeting risk of passing trains is identified for both of the above - mentioned pairs of adjacent lines, can the departure route of the SN port in station B be arranged.

[0140] As a preferred implementation method, the non - meeting train multi - line passing risk identification and prevention and control scheme includes:

[0141] When the train instruction of the target departure port reaches the trigger timing for arranging the route, obtain the adjacent - line objects and the quantity, judge the train operation direction of the first adjacent line. If it is determined as the risk of meeting face - to - face between stations, call the risk judgment logic for meeting face - to - face between stations of non - meeting trains to implement prevention and control;

[0142] If it is determined as the risk of meeting in the same direction between stations, call the risk judgment logic for meeting in the same direction between stations of non - meeting trains to implement prevention and control;

[0143] When it is judged that there is a risk of meeting between stations with the first adjacent line, give an alarm prompt and continuously monitor until the conflict is eliminated;

[0144] If it is judged that there is no risk of meeting between stations with the first adjacent line or the conflict is eliminated, then continue to judge the risk of meeting with the second adjacent line;

[0145] And so on until it is judged that there is no risk of meeting with all adjacent lines, then arrange the route of the target departure port. Embodiment 2
