Description

Technical Field

[0001] The present invention relates to the field of train line allocation, and in particular to a train control system and a train control method based on a local TSRS. Background Art

[0002] CTCS (Chinese Train Control System) is a train control system that is designed to ensure train operation safety and meet the transportation needs of different lines in a graded manner. The CTCS includes a number of ground equipment and on-board equipment to control the corresponding trains. The current mainstream train control systems include CTCS0 ​​(Chinese Train Control System Level 0), CTCS2 (Chinese Train Control System Level 2) and CTCS3 (Chinese Train Control System Level 3). In specific applications, different lines implement operation control of different trains by carrying different train control systems. In addition, the Chinese train control system is often composed of lower-level train control systems with different functions, such as lower-level train control systems with deceleration functions, speed control functions, etc. The present invention focuses on the speed control function when the train crosses different lines.

[0003] Specifically, any of the above-mentioned lower-level train operation control systems includes a TSRS (Temporary Speed ​​Restriction Server) and multiple TCCs (Train Control Centers), and the multiple TCCs are connected to the corresponding TSRS, and the multiple TCCs are connected to the train; the TSRS sends a start instruction to the corresponding TCC based on external information, so as to realize the TCC controlling the running speed of the train. It can be understood that the start instruction is an instruction to make the TCC enter an active working state, otherwise the TCC will be in a dormant state, controlling the train to run at a safe speed.

[0004] In the specific application when the train crosses different lines, because each TCC has a corresponding TSR (Temporary Speed ​​Restriction) jurisdiction, the corresponding TCC can only control the train when and only when the train is in its corresponding TSR jurisdiction. Therefore, when it involves the train crossing the line, it will involve the overlap between the TSR jurisdictions of multiple TCCs in the two lines.

[0005] At this time, there are certain difficulties in handling speed control between the two lines and how to handle multiple TCCs. For example, there is bound to be a certain overlap in the TSR jurisdiction between the two lines. If it is too safety-oriented, the TCC will not receive the start command every time the line is crossed, and the train will run at a safe speed in this section. This will cause the trains in the TSR jurisdiction corresponding to the corresponding TCC to be unable to run at normal operating speeds. How to coordinate trains to cross the boundaries between different lines has become an urgent problem that needs to be solved. Summary of the invention

[0029] The following will be combined with the attached embodiment of the present invention Figure 1 ~Attached Figure 4 , the technical solutions, structural features, objectives achieved and effects in the embodiments of the present invention are described in detail.

[0030] It should be noted that the drawings are in a very simplified form and use non-precise proportions. They are only used to conveniently and clearly assist in explaining the embodiments of the present invention, and are not used to limit the conditions for the implementation of the present invention. Therefore, they have no substantive technical significance.

[0031] It should be noted that, in the present invention, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only the elements explicitly listed, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0032] like Figure 1and Figure 2 As shown, the present invention provides a train control system based on local TSRS, which is used to perform corresponding speed control on trains from adjacent lines to local lines; wherein the local line refers to the destination line that the train needs to reach, and the adjacent line refers to the adjacent line that the train must pass through to enter the local line.

[0033] The train control system comprises:

[0034] Adjacent train control system, connected to the train signal, used to control the speed of the train on the adjacent line;

[0035] The local control system is connected to the train signal and the adjacent train control system signal to control the speed of the train on the local line.

[0036] Among them, the adjacent train control system includes: an adjacent TSRS (Temporary Speed ​​Restriction Server) and multiple adjacent TCCs (Train Control Center), the multiple adjacent TCCs are respectively connected to the adjacent TSRS signal, and any adjacent TCC is connected to the train signal; wherein the adjacent TSRS and multiple adjacent TCCs are fixedly set on the adjacent line running path of the train.

[0037] Wherein, the local control system includes: a local TSRS and multiple local TCCs, and the multiple local TCCs are respectively connected to the local TSRS signal; the local TSRS is connected to the adjacent TSRS signal, and any local TCC is connected to the train signal; wherein, the local TSRS and multiple local TCCs are fixedly set on the local line operation path of the train.

[0038] Each adjacent / local TCC has a corresponding TSR (Temporary Speed ​​Restriction) jurisdiction. When a train is within the TSR jurisdiction, the corresponding adjacent / local TCC controls the running speed of the train within the TSR jurisdiction.

[0039] The adjacent / local TSRS receives external information and sends a start instruction to the corresponding adjacent / local TCC according to the external information. The adjacent / local TCC controls the train to run in a safe state when the start instruction is not received. The external information includes information from, for example, the train's interlocking system, the train's computer operation system, other TSRS, and the radio control center. Specifically, the external information is information that determines whether the adjacent / local TSRS generates a corresponding start instruction for the adjacent / local TCC and what kind of start instruction is generated. It can be understood that after the adjacent / local TCC receives the start instruction, the corresponding adjacent / local TCC will enter the working state of actively controlling the running speed of the train; otherwise, the train will not be actively controlled by the corresponding adjacent / local TCC, but will run at a safe speed.

[0040] Any of the adjacent / local TCCs controls the speed of the train on the adjacent / local line according to the start command from the adjacent / local TSRS. In addition, the related technology of the present invention regarding the generation of the start command is based on the prior art. The focus of the present invention is on the control of the train speed. The detailed generation method and process of the start command are not described here.

[0041] Specifically, any of the adjacent / local TCC controls the running speed of a train within the jurisdiction of the corresponding TSR (Temporary Speed ​​Restriction). Figure 2 As shown, in the case where there is overlap between the TSR jurisdictions corresponding to different TCCs, the overlapping TSR jurisdictions are handled by adopting the method of giving priority to the latest TCC and controlling the train, as described below for details.

[0042] On the basis of adopting the above train control system, the normal operation of the train speed in the process of moving from the adjacent line to the local line is realized. The present invention proposes a train control method based on local TSRS, the method comprising:

[0043] Step S1, marking the boundary TCC of the local line;

[0044] Specifically, the border TCC refers to a local TCC that overlaps with the TSR jurisdiction of the adjacent line;

[0045] For example, Figure 2 In the shown part, the local line shows 4 local TCCs. The TSR jurisdictions of these 4 local TCCs overlap with the TSR jurisdictions of the adjacent lines. The brown part in the figure is the TSR jurisdiction of the adjacent lines, so these 4 local TCCs are all marked as boundary TCCs.

[0046] Step S2, obtaining the start command reception status of all adjacent TCCs. If all adjacent TCCs receive the start command, the train enters the local line at normal speed and proceeds to step S4; if not, proceeds to step S3;

[0047] Step S3, check whether there is a boundary TCC that overlaps with the dispatch range of the adjacent line and has received the start instruction. If so, enter the local line at normal speed and enter step S4; if not, enter the local line at safe speed and enter step S4;

[0048] Among them, Figure 1 As shown in FIG. 1 , the dispatch range refers to the actual segment division range of the local line and the adjacent line. The dispatch range is different from the TSR jurisdiction range. The dispatch range of the local line and the adjacent line has a clear dividing line, such as Figure 1 The purpose of this step is to capture whether there is a "responding" boundary TCC in the local line (that is, it overlaps with the dispatching scope of the adjacent line and has received the start-up instruction) when it is impossible to ensure that the trains are controlled by the adjacent TCC in the entire adjacent line. The significance of measuring with the dispatching scope is that compared with the conceptual TSR jurisdiction (its essence is to determine the scope through wireless signals), the dispatching scope is more accurate and ensures driving safety.

[0049] Therefore, when there is a "tackling" boundary TCC, the train can enter the local line at normal speed;

[0050] When there is no "connecting" boundary TCC, the train must enter the local line at a safe speed; specifically, when the train runs to the dispatching boundary of the adjacent line and the local line at most, the train speed will be forced to become a safe speed. If it is already a safe speed, it can be maintained; in addition, the judgment from large-scale adjacent TCC to small-scale boundary TCC is adopted to ensure the rationality of the entire process inspection and ensure that each adjacent TCC is captured by the adjacent TSRS. The data captured by this adjacent TSRS, as mentioned above, is also a kind of external information and can be used to generate local TSRS related startup instructions.

[0051] Step S4, after entering the local line, the local TSRS sends a start instruction to the corresponding local TCC according to the external information, and the corresponding local TCC controls the operation of the train;

[0052] At this time, because the train has been running on the local line at a certain speed, the TSRS of the local line can control the running speed of the train through the local TCC without any obstacles.

[0053] When the TSR jurisdictions of different adjacent / local TCCs overlap, the question of which TCC the train is controlled by is, as mentioned above, the latest TCC takes priority; Figure 2 As shown, after entering the local line, there is an overlap between the TSR jurisdiction of the local TCC1 (border TCC1) and the TSR jurisdiction of the local TCC2 (border TCC2). However, after entering the local line, the train will first enter the TSR jurisdiction of the local TCC1 (border TCC1) and then enter the TSR jurisdiction of the local TCC2 (border TCC2). Therefore, when the train enters the TSR jurisdiction of the local TCC2 (border TCC2), the local TCC2 (border TCC2) is the current latest TCC. Based on the principle of the latest TCC priority, even if there is an overlap in the TSR jurisdiction of the local TCC1 (border TCC1), the train still takes the command of the local TCC2 (border TCC2) as the highest priority.

[0054] Specifically, the corresponding embodiments of step S4 are listed below:

[0055] (1) After the train enters step S4 in step S2, when the train enters the local line at normal speed, the local TSRS does not send a start command to any local TCC. At this time, all local TCCs make the train run at a safe speed.

[0056] After entering the local line, since the local TCC does not receive the start command, it will not control the speed of the train. Therefore, after entering the local line, the train will change from normal speed to safe speed. Figure 2 As shown, if none of the four boundary TCCs receives the start command from the local TSRS, the trains within their TSR jurisdiction will not be actively controlled by the local TCC, and the trains will drop to a safe speed within the overlapping part of the boundary TCC1 and the TSR jurisdiction of the adjacent line. The trains within the TSR jurisdiction of the four boundary TCCs can only run at a safe speed, and so on.

[0057] (2) After the train enters step S4 in step S2, when the train enters the local line at normal speed, when the local TSRS sends a start command to the corresponding local TCC, the local TCC makes the train run in a corresponding manner;

[0058] For example, if boundary TCC1 does not receive the start command, but boundary TCC2, boundary TCC3, and boundary TCC4 receive the start command, the train will enter a safe speed within the overlapping TSR jurisdiction of boundary TCC1 and boundary TCC2, and then run at a normal speed within the TSR jurisdiction of boundary TCC2 / boundary TCC3 / boundary TCC4.

[0059] For another example, if the train runs beyond the boundary TCC2, boundary TCC3, or boundary TCC4, if the corresponding other local TCCs do not receive the start command, the train will return to the safe speed to ensure driving safety. Specifically, for example, if boundary TCC3 receives the start command, and boundary TCC4 does not receive the start command, the train will run at a normal speed within the TSR jurisdiction of boundary TCC3 that does not overlap with boundary TCC4, but when the train enters the TSR jurisdiction of boundary TCC4, the train will reduce to a safe speed.

[0060] (3) After the train enters step S4 in step S3, when the train enters the local line at a safe speed, the local TSRS does not send a start command to any local TCC. At this time, all local TCCs make the train run at a safe speed.

[0061] (4) After the train enters step S4 in step S3, when the train enters the local line at normal speed and when the local TSRS does not send a start command to any local TCC other than the boundary TCC1, the train will run at a safe speed.

[0062] For example, if Boundary TCC2, Boundary TCC3, and Boundary TCC4 do not receive a start command from the local TSRS, the train will slow down to a safe speed in the overlapping TSR jurisdiction of Boundary TCC2 and Boundary TCC1.

[0063] (5) After the train enters step S4 in step S3, when the train enters the local line at a safe speed, when the local TSRS sends a start command to the corresponding local TCC, the local TCC enables the train to run in a corresponding manner, as described above and will not be repeated here.

[0064] (6) After the train enters step S4 in step S3, when the train enters the local line at normal speed, when the local TSRS sends a start command to the corresponding local TCC, the local TCC makes the train run in a corresponding manner, as described above and will not be repeated here.

[0065] As described above, the present invention can ensure the running efficiency of the train while enabling the local line to perform corresponding work without being affected by the adjacent line when the train is not operating normally on the adjacent line or the corresponding adjacent TCC has not received the start command.

[0066] Moreover, trains entering the local line will be directly replaced and controlled by the local TCC, and there will be no conflict with the adjacent TCC of the adjacent line. In addition, in order to ensure that trains entering the local line at normal speed can continue to travel at normal speed and prevent accidents of TCC priority control, the present invention subsequently proposes a method for maintaining the normal speed of the train by the local TCC (see below for details).

[0067] like Figure 4 As shown, the present invention also proposes a method for maintaining the normal speed of a train by a local TCC, the purpose of which is to ensure the coordination of trains entering the local line from the adjacent line, and for trains entering the local line at a normal speed, require all local TCCs that overlap with the TSR jurisdiction of the adjacent line to further maintain the normal speed after receiving the start instruction;

[0068] The method comprises:

[0069] Step Q1, selecting any local TCC on the local line;

[0070] Step Q2, determining whether the TSR jurisdiction of the local TCC overlaps with the TSR jurisdiction of the adjacent line, if not, returning to step Q1, if yes, proceeding to step Q3;

[0071] Step Q3: Determine whether the local TCC has received the start command, if it has, return to step Q1, if not, go to step Q4;

[0072] Step Q4: The local TSRS sends a start instruction to the local TCC;

[0073] like Figure 3 As shown, after receiving external information, the local TSRS sends a start instruction to the local TCC;

[0074] Step Q5: Check whether all local TCCs on the local line have been judged. If not, return to step Q1; if so, end the process.

[0075] The premise for the application of this method is that the train enters the local line at normal speed, such as Figure 2 and Figure 3As shown, at this time, whether all adjacent TCCs of the adjacent lines receive the start command or there is a boundary TCC1 that has received the start command and overlaps with the scheduling range of the adjacent line, it will enter the local line at a normal speed; at this time, if it is necessary to ensure the coordination and consistency of train operation, the above method needs to ensure that local TCC1, local TCC2, local TCC3, and local TCC4 are in a state of receiving the start command; this method can be applied when the TSR jurisdiction of the adjacent line and the TSR jurisdiction of the local TCC overlap, because it involves the interaction between different TSRS, it can avoid the situation where the local TCC controlling the train and the TCC of the adjacent line have priority judgment errors, further reducing the probability of train operation failures.

[0076] Although the content of the present invention has been described in detail through the above preferred embodiments, it should be appreciated that the above description should not be considered as a limitation of the present invention. After reading the above content, it will be apparent to those skilled in the art that various modifications and substitutions of the present invention will occur. Therefore, the protection scope of the present invention should be limited by the appended claims.
