Description

Technical Field

[0001] The present invention relates to the technical field of train operation risk identification, and in particular to a method and system for identifying and preventing risks of forbidden trains passing between stations, thereby realizing a method for identifying and preventing risks of forbidden trains passing between stations based on a CTC system. Background Art

[0002] The Centralized Traffic Control (CTC) system monitors the signal equipment and train operation conditions within the section under its jurisdiction, optimizes the train operation plan, coordinates train shunting operations, strictly controls the route arrangement within the station according to the train plan, and ensures the efficiency and safety of railway transportation. It is an important part of railway high-end equipment manufacturing. Its main functions include train position tracking, route control within the station, and fault detection and processing. Specifically: (1) Train location tracking: The CTC system obtains the train number through G network / 450M wireless train number information or manual confirmation and other technical means, and monitors and tracks the train operation status through track circuit collection information or section train control information, and provides real-time feedback to the system's station display interface, making it easier for relevant staff to understand the train operation status and providing basic data for the system's decentralized autonomous control.

[0003] (2) Station route control: The CTC system adopts a decentralized autonomous mode and sends control commands to the interlocking system based on the train operation adjustment plan to achieve automatic control of the train route arrangement within the station. Specifically, it controls the opening and closing of station route signals, locking and clearing of routes, positioning and reversing of route turnout objects, and alarming when route conditions are not met.

[0004] (3) Fault detection and processing: The CTC system monitors the status of trains and signal equipment, automatically analyzes and identifies faults, and sends prompt messages in a timely manner. The CTC system has established a complete and reliable communication system to achieve information exchange between the center and stations, stations and stations, and stations and trains. In this way, after a fault is detected, the fault information can be accurately pushed to the electrical maintenance equipment.

[0005] When trains on two tracks meet each other between railway stations, there may be a risk of emergency braking or even collision due to factors such as the shortest distance between the two tracks, the width of the train body, and the speed of the train. Therefore, it is required that two trains of specific types (with different body widths) or two trains of the same type are prohibited from meeting each other between stations. Identification and prevention of the risk of trains that are prohibited from meeting each other between stations has always been a key issue of railway driving safety and one of the special work contents that needs to be improved urgently. The current prevention measures for trains that are prohibited from meeting each other between stations include: (1) Initially, the prevention method for prohibited trains to pass each other between stations was to manually identify the risk, and when handling the block between stations, the receiving station would notify the adjacent departure station that the departure was prohibited, and the departure station attendant would control the departure route arrangement of the corresponding port to prevent prohibited trains from entering the section. However, with the increase in railway passenger and freight transportation business and the increase in locomotive operating speed, manual identification of such risks can no longer meet actual needs from the perspective of accuracy and timeliness.

[0006] (2) The CTC system reduces the risk of trains that are prohibited from meeting each other to a certain extent. It identifies the type of train by the train number of the train running in the interval and automatically controls the route of the departure port of the adjacent line according to the established rules for prohibiting meeting, ensuring that the other type of train that is prohibited from meeting each other will not enter the interval. However, the main problems with this technology include: on the one hand, the correspondence between the train number and the type of train may be updated and changed, and the accuracy of the judgment of the type of train cannot be guaranteed; on the other hand, this method is only effective when one train has entered the interval. If the departure route has been arranged at the adjacent station but the train has not yet entered the interval, it cannot be effectively controlled.

[0007] Therefore, there is a necessity to design new methods and systems for identifying and preventing risks of forbidden train crossing between stations. Summary of the invention

[0012] Preferably, the step of identifying the port of the line based on the inter-station adjacent line port identification logic and the adjacent line after judgment, and finally identifying the adjacent line port includes: At the same time, search for the local port and the neighboring port. The local code is B and the neighboring code is C. 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. For traversal search of neighboring station ports, 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 direction is to receive the train, it is determined that the trains are running in opposite directions between stations. Check the type of trains running in the section, and determine whether the types of trains departing from the station and trains running in the section meet the prohibition of meeting 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; 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 are analyzed in turn to find plans whose train types conflict with the train type 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. If a plan with conflicting train types is found, and the plan status is successful or occupied, 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; If the conflicting plan status is waiting and the planned time is earlier than the target port departure time, the target port departure route will 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 the current station, the conflict is considered to be resolved.

First, determine whether the departure train in the station and the train type running in the section are prohibited from meeting according to the established rules. If they are required to be prohibited from meeting, further confirm whether the maximum speed of the train at the target port is greater than the speed of the prohibited type of train in the section. If the above two conditions are met, it is considered that there is a risk of meeting and a conflict. The port departure route is suspended, and an alarm is issued and continuous monitoring is carried out. If the conflicting train enters the adjacent station, it is considered that the conflict is eliminated. 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 the adjacent line ports are analyzed in turn to find the 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 and no conflict.

If the conflicting train enters the adjacent station, the conflict is considered to be resolved; If the conflicting plan status is waiting and the planned time is earlier than the target port departure time, the target port departure route will be suspended, and an alarm will be issued and continuously monitored. If the conflicting train leaves the station and enters the adjacent station, the conflict is considered to be resolved.

[0019] Beneficial effects of the method and system of the present invention: This prevention and control plan aims to identify the risk of prohibited trains crossing between stations earlier and more accurately, blocking the risk of prohibited trains crossing between stations at the railway signal control system level, reducing the labor intensity of train dispatchers, and playing a positive and effective role in safety and technical defense and improving lean and efficient command capabilities. At the same time, it expands the system extension direction and enriches the system functions without changing the CTC system structure, providing new ideas for the safe and intelligent development of the CTC system. It is mainly manifested in: (1) Within the existing CTC system framework, we deeply mine and analyze the existing system data, establish new logical relationships, identify the possible risks of forbidden trains crossing between stations, and then develop effective and feasible prevention and control plans to prevent such risks from occurring.

In terms of time, take into account the scheduled times of all trains on adjacent lines and release trains into the section in strict accordance with the scheduled time to prevent the situation where prohibited trains pass each other between stations due to failure to comply with the scheduled time. In terms of space, in addition to monitoring the trains running in the section, expand the monitoring of departures within the station to prevent the situation where two adjacent stations release prohibited trains into the double-track section at the same time.

Figure 1 There are inter-station lines in both the up and down directions between stations A and B. These two lines are adjacent lines. Taking port X of station A as an example, the port of the adjacent line at this station is port XN of station A, and the port of the adjacent line at the next station is port S of station B.

[0029] 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: (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; (2) Identify the attributes of the target port, 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); (3) Determine the adjacent line ID (A1) of any line by using a predetermined rule, wherein the predetermined rule is: the inter-station lines with line IDs A and A1 are adjacent lines to each other; (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: At the same time, search for the local port and the neighboring port.

[0031] 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 and autonomous subsystem can directly obtain all port plans of this station, so there is no need to obtain the port plan of the adjacent line in advance, and it can be directly captured when risk identification and judgment are made.

[0037] S2. Determine a corresponding intersection risk identification and control plan based on the key information of the risk of crossing between forbidden trains and the types of intersection scenarios between trains, wherein the types of intersection scenarios between trains include intersections in the opposite direction, intersections in the same direction and intersections of multiple lines, and the intersection risk identification and control plan includes an identification and control plan for the risk of crossing in the opposite direction between forbidden trains, an identification and control plan for the risk of crossing in the same direction between forbidden trains and an identification and control plan for the risk of crossing multiple lines between forbidden trains.

[0039] like Fig. 9 As shown, the risk identification and prevention plan for the prohibited trains crossing each other between stations includes: When the train instruction of the target departure port reaches the triggering time, the receiving and dispatching direction of the port of the adjacent line is checked. If the direction is to receive the train, it is determined that the trains are running in opposite directions between stations. Check the type of trains running in the section, and determine whether the types of trains departing from the station and trains running in the section meet the prohibition of meeting 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; 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 are analyzed in turn to find plans whose train types conflict with the train type 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. If a plan with conflicting train types is found, and the plan status is successful or occupied, 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; If the conflicting plan status is waiting and the planned time is earlier than the target port departure time, the target port departure route will 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 the current station, the conflict is considered to be resolved. 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 is passed and it is considered that there is no risk of inter-station intersection; Perform change checks on the above conflict contents to ensure that the same conflict will not cause repeated alarms.

[0040] S22, determining the risk identification and prevention plan for the forbidden-meeting trains crossing in the same direction between stations based on the forbidden-meeting trains crossing risk key information and the train crossing scenario between stations for the same-direction crossing; like Fig.10 As shown in the diagram of train crossing in the same direction between stations, 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 identification of crossing risk in this scenario requires an additional necessary judgment condition: the maximum speed of the rear vehicle is greater than that of the front vehicle.

[0041] like Fig.11 As shown, the risk identification and prevention plan for the forbidden trains crossing in the same direction between stations includes: When the train instruction of the target departure port reaches the triggering timing, 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; Check the type and maximum speed of the trains running in the section. First, determine whether the departure train in the station and the train type running in the section are prohibited from meeting according to the established rules. If they are required to be prohibited from meeting, further confirm whether the maximum speed of the train at the target port is greater than the speed of the prohibited type of train in the section. If the above two conditions are met, it is considered that there is a risk of meeting and a conflict. The port departure route is suspended, and an alarm is issued and continuous monitoring is carried out. If the conflicting train enters the adjacent station, it is considered that the conflict is eliminated. 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 the adjacent line ports are analyzed in turn to find the 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 and no conflict. If a plan with conflicting train types is found, and the plan status is successful or occupied, 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 adjacent station, the conflict is considered to be resolved; If the conflicting plan status is waiting and the planned time is earlier than the target port departure time, the target port departure route will be suspended, and an alarm will be issued and continuously monitored. If the conflicting train leaves the station and enters the adjacent station, the conflict is considered to be resolved. 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 is passed and it is considered that there is no risk of inter-station intersection; Perform change checks on the conflicts mentioned above to ensure that the same conflict does not cause repeated alarms.

[0042] S23, determining the risk identification and prevention plan for the prohibited trains crossing multiple lines based on the key information of the prohibited trains crossing between stations and the scenario of the train crossing between stations being a multi-line crossing; like Fig.12 As shown in the schematic diagram of multiple adjacent lines, there is a special interval adjacent relationship in actual situations, that is, one interval line has two adjacent lines at the same time. Interval line 1 is adjacent to interval line 2 and interval line 3 respectively. Therefore, when sending trains to interval line 1 and identifying the risk of forbidden meeting between stations, it is necessary to consider the driving conditions of interval lines 2 and 3 and the plan of sending trains to these two intervals at the same time. Taking the SN port of station B in the figure as the target departure port, identify the forbidden meeting risk between lines 1 and 2, take the S port of station C as the adjacent line station port, and the XN port of station A as the adjacent line adjacent station port, and monitor the receiving and dispatching direction of the S port of station C; similarly, to identify the forbidden meeting risk between lines 1 and 3, it is necessary to take the S port of station B as the adjacent line station port, and the XN port of station C as the adjacent line adjacent station port, and monitor the receiving and dispatching direction of the S port of station C. Only when the above two groups of adjacent lines do not identify the forbidden meeting risk, can the departure route of the SN port in station B be arranged.

[0043] As a preferred implementation, the risk identification and prevention scheme for multi-line crossing of trains prohibited from meeting each other includes: When the train instruction of the target departure port reaches the triggering time for route arrangement, the adjacent line objects and their numbers are obtained, and the train running direction of the first adjacent line is determined. If it is determined to be a risk of crossing between stations, the risk judgment logic of crossing between stations with prohibited trains is called to perform prevention and control; If it is determined that there is a risk of crossing in the same direction between stations, the risk judgment logic of crossing in the same direction between stations with prohibited trains is called to implement prevention and control; When it is determined that there is a risk of intersection between stations and the first adjacent line, an alarm will be issued and continuous monitoring will be carried out until the conflict is eliminated; If it is determined that there is no risk of intersection between stations or the conflict with the first adjacent line is eliminated, the intersection risk with the second adjacent line will continue to be determined; This process is repeated in this way until it is determined that there is no risk of intersection with all adjacent lines, and then the target departure port approach is arranged.
