Description

Technical Field

[0001] The present invention relates to the technical field of rail transit resource management, and in particular to a track section management method, device and medium based on line resource management. Background Art

[0002] The Computer Based Interlocking System (CI) in the existing signal system (CBTC) locks the track section according to the route handling command of the Automatic Train Supervisor (ATS), thereby establishing the required path for the train to run to the front.

[0003] In the more efficient next-generation signal system, the interlocking system is replaced by the Resource Management Unit (RMU). The RMU can dynamically lock or release the path required for the train's operation based on its resource application. The path is not divided by traditional track sections, which effectively improves the train's operating efficiency and operational flexibility in the section.

[0004] In order to apply RMU to improve driving efficiency on the reconstructed line and be compatible with the usage habits of the existing signal system, RMU still needs to receive the route processing command from ATS, lock the corresponding path, and provide the locking status in units of track sections.

[0005] How to achieve track section management based on line resource management to improve train operation efficiency has become a technical problem that needs to be solved. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a track section management method, equipment and medium based on line resource management.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] According to one aspect of the present invention, a track section management method based on line resource management is provided, the method comprising a track section locking sub-method and a track section unlocking sub-method;

[0009] The track section locking sub-method comprises the following steps:

[0010] Step S11, the resource manager regards the route handling command and turnout single locking command of the ATS, as well as the resource application request of the train as line resource application;

[0011] Step S12: After the line resource application passes the hostile check, the corresponding line resource is set to a locked state;

[0012] Step S13: When the range of the track section and the range of any line resource intersect, if any of the line resources included in the track section is in a locked state, the track section is in a locked state;

[0013] The track segment unlocking sub-method comprises the following steps:

[0014] Step S21, the resource manager regards the route cancellation command, route manual unlocking command and turnout single release command of the ATS, and the resource release request of the train as line resource release;

[0015] Step S22: Release of line resources: After the validity check is passed, the corresponding locked line resources are set to unlocked state;

[0016] Step S23: When the range of the track segment and the range of any line resource intersect, if all the line resources included in the track segment are in unlocked state, the track segment is in unlocked state.

[0017] Preferably, the line resources include path resources, side protection resources and cross resources.

[0018] Preferably, the hostile check is used to ensure that the locking state of the resource is consistent with the target of the upper layer line resource application.

[0019] Preferably, the legitimacy check is used to ensure that the unlocking state of the resource is consistent with the target of releasing the upper layer line resource.

[0020] More preferably, the locking states of the path resources include "locked in the uplink direction" and "locked in the downlink direction"; the locking states of the side defense resources include "locked in the positioning path", "locked in the reverse path", "locked in the positioning conflict" and "locked in the reverse conflict"; the locking states of the cross resources include "locked in the path side" and "locked in the conflict side";

[0021] The unlocking status of the path resources, side protection resources and cross resources all include "unlocked".

[0022] More preferably, the resource manager uses a "train unlocking point" to unlock each line resource in a locked state, wherein the "train unlocking point" is the position of the minimum rear safety position of the train and then extends to the rear of the train to set the rear sliding distance.

[0023] More preferably, when the "train unlocking point" passes through the path resource locked in the direction along the train running direction, the path resource is released;

[0024] When the "train unlocking point" passes through a certain track section, all path resources upstream of the track section are unlocked.

[0025] More preferably, when the "train unlocking point" passes through the side defense resource at the first position of the turnout, the side defense resource is released; at the same time, the side defense resource at the second position of the turnout that conflicts with it is also released because the conflicting side resource is released.

[0026] More preferably, when the "train unlocking point" passes through the second crossover resource associated with the crossover, the crossover resource is released; at the same time, the first crossover resource that conflicts with the crossover resource is also released because the conflicting side resource is released.

[0027] Preferably, if the resource manager receives a route cancellation command from the ATS, and the path between the starting point and the end point is clear and no train is about to enter the corresponding area, the corresponding line resources will be released immediately and all track sections therein will be unlocked immediately.

[0028] More preferably, if the resource manager receives a command from the ATS to lock the turnout in the first position, the side defense resource of the turnout in this position will be in a locked state, the side defense resource of the turnout in the second position will be in a locked conflict state, and the corresponding track section will be locked;

[0029] Only when the resource manager receives the turnout single release command sent by ATS can the corresponding line resources be released and the corresponding track section be unlocked.

[0030] More preferably, the first position and the second position both include a positioning position and an anti-position, and the first position is different from the second position.

[0031] According to another aspect of the present invention, an electronic device is provided, comprising a memory and a processor, wherein a computer program is stored in the memory, and the method described above is implemented when the processor executes the program.

[0032] According to a third aspect of the present invention, there is provided a computer-readable storage medium having a computer program stored thereon, wherein the program implements the method described above when executed by a processor.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1) The present invention integrates line resource management into track section management. The route handling / cancellation commands of ATS, the single locking / single unlocking commands of switches, and the resource application / release requests of trains are all regarded as line resource application / release for management. When the scope of a track section intersects with the scope of any line resource, if any one of all the line resources included in the track section is in a locked state, then the track section is in a locked state; if all the line resources included in the track section are in an unlocked state, then the track section is in an unlocked state. By integrating the resource locked state and the track section locked state, the line resource management is made compatible with the existing signal system, improving the compatibility and usability of the renovated line, as well as the train operation efficiency.

[0035] 2) The present invention uses the "train unlocking point" to release each resource. When the "train unlocking point" passes through a certain line resource, the corresponding resource is released, and the corresponding track section is also unlocked section by section as the train runs; managing track sections in units of line resources has a finer granularity of division compared to interlocking, so trackside equipment can be controlled more precisely, thereby improving train operation efficiency.

[0036] 3) The present invention integrates the algorithms of line resource management and track section management in a complementary manner, improving the unity of the line resource management software algorithm and enhancing the usability and maintainability of the line resource management algorithm.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0045] This embodiment relates to a track section management method based on line resource management, such as Figure 1 , the method comprises the following steps:

[0046] Step A: RMU regards the route handling command and turnout single locking command of ATS and the resource application request of train as line resource application. Figure 2 and Figure 3 , RMU regards the route cancellation command, route manual unlocking command, turnout single release command and train resource release request from ATS as line resource release. The command from ATS and the resource request from train in this step are Figure 1 Request to apply for or release external resources in.

[0047] Step B: After the hostile check is passed, the corresponding path resources, side defense resources and cross resources are locked. Figure 2 and Figure 3 , after the legitimacy check is passed, the line resource release sets the corresponding locked path resources, side protection resources and cross resources to the unlocked state. Figure 1 The internal resources refer to: path resources, side defense resources and cross resources.

[0048] Both the hostile check and the legitimacy check are to avoid locking or unlocking the wrong resources, so as to ensure that the locked or unlocked state of the resources is consistent with the target of the upper-layer line resource application or line resource release.

[0049] Among them, the locking status of path resources includes "locked in the upstream direction" and "locked in the downstream direction"; the locking status of side defense resources includes "locked in the positioning path", "locked in the reverse path", "locked in the positioning conflict" and "locked in the reverse conflict"; the locking status of cross resources includes "locked in the path side" and "locked in the conflict side"; the unlocking status of the above resources includes "unlocked".

[0050] Step C: When the range of a track segment and the range of any line resource intersect, the track segment is said to contain the line resource. If any of the line resources contained in a track segment is in a locked state, the track segment is locked. If all the line resources contained in a track segment are in an unlocked state, the track segment is unlocked.

[0051] Assume that the ATS commands the RMU to handle a route from the starting point to the end point, or the train applies for resources between the starting point and the end point. Figure 4 If agreed Figure 4 If the direction from the start point to the end point is the upward direction, then if these path resources were previously in the "unlocked" state, they will now be in the "locked in the upward direction" state.

[0052] Side defense resources between the starting point and the end point are as follows: Figure 5 As shown. The position of turnout 1 includes the fixed position and the reverse position. If these side defense resources were previously in the "unlocked" state, the side defense resources of turnout 1 reverse position will now be in the "locked in reverse position path" state, and the side defense resources of turnout 1 fixed position will be in the "locked in reverse position conflict" state.

[0053] The cross resources between the starting point and the end point are as follows Figure 6 As shown. The turnout of the crossing line is associated with a pair of crossing resources, namely: the first crossing resource ( Figure 6 The "apostrophe" type cross resource a) and the second cross resource ( Figure 6 b) If these cross-link resources were previously in the "unlocked" state, the second cross-link resource of cross-link 1 will now be in the "locked on the path side" state, and the first cross-link resource of cross-link 1 will be in the "locked on the conflict side" state.

[0054] After the above resources are locked, no matter how the track segments are divided, the track segments that intersect with the ranges of the above resources will be locked.

[0055] In the scenario of processing train resource release, RMU uses the "train unlocking point" (that is, the position where the train's minimum rear end safety positioning is extended to the rear of the train to set the backward sliding distance) to unlock the above resources.

[0056] When the "train unlocking point" passes through the path resource locked in the direction of train operation, the path resource is released. Figure 4 In the example, if a train runs from the starting point to the end point, and its running direction is upward, then after the train unlocking point passes the end point, the path resources "locked in the upward direction" between the starting point and the end point are unlocked. More specifically, when the train unlocking point passes a certain track section, all the path resources upstream of the track section are unlocked.

[0057] exist Figure 5 In the example, when the train unlocking point passes through the side defense resource of the first position (reverse position) of turnout 1 "locked in the reverse position path", the side defense resource is released. At the same time, the side defense resource of the second position (positioning) of turnout 1 "locked in the reverse position conflict" is also released because the conflicting side resource is released.

[0058] The locking and releasing principle of the side defense resources of turnout 1 positioning is the same as that of the reverse position.

[0059] exist Figure 6 In the example, when the "train unlocking point" passes through the second intersection resource "locked on the path side" of intersection 1, the intersection resource is released. At the same time, the first intersection resource "locked on the conflicting side" of intersection 1 that conflicts with it is also released because the conflicting side resource is released.

[0060] When the "train unlocking point" passes through the first cross resource, the locking and unlocking of the corresponding resource are the same as the second cross resource.

[0061] In the above resource release process, if all resources contained in a track section are released, the track section is unlocked. Therefore, according to the division granularity, the track section can also be unlocked section by section as the train runs.

[0062] In addition, if ATS sends a route cancellation command, and the path between the starting point and the end point is clear and there is no train about to enter the area, the above-mentioned line resources will be released immediately and all the track sections therein will be unlocked immediately.

[0063] In another scenario, for example, when the ATS sends a command to lock the second position (positioning) of the single turnout 1, the side defense resources of the second position (positioning) of the turnout 1 will be in the "locked in the positioning path" state, and the side defense resources of the first position (reverse position) of the turnout 1 will be in the "locked in positioning conflict" state, and the corresponding track section will be locked. Only when the ATS sends a command to release the single turnout 1 can these resources be released and the corresponding track section be unlocked.
