Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rail transit resource management, and in particular to a rail section management method based on line resource management, equipment and medium. BACKGROUND

[0002] In the existing signal system (CBTC), the interlocking system (CI) locks the track section according to the route handling command of the automatic supervision system (ATS), thereby establishing the required path for the train to run to the front.

[0003] In the next-generation signal system, the interlocking system is replaced by the resource manager (RMU). The RMU can dynamically lock or release the path required for the train to run according to the resource application of the train, and the path is not divided by the traditional track section, which effectively improves the running efficiency of the train and the operation flexibility in the section.

[0004] In order to apply the RMU on the reconstructed line to improve the train operation efficiency, and to be compatible with the use habit of the existing signal system, the RMU still needs to receive the route handling command of the ATS, lock the corresponding path, and provide the locking state in the unit of track section.

[0005] How to realize track section management based on line resource management to improve the train running efficiency becomes a technical problem to be solved. SUMMARY

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

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

[0011] Step S12, after the line resource application passes the hostile check, the corresponding line resource is set to the locking state;

[0012] Step S13, when the range of the track section and the range of any one of the line resources have intersection, if all the line resources contained in the track section are in the locked state, the track section is in the locked state;

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

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

[0015] Step S22, the line resource release sets the corresponding locked line resource to the unlocked state after the legality check;

[0016] Step S23, when the range of the track section and the range of any one of the line resources have intersection, if all the line resources contained in the track section are in the unlocked state, the track section is in the unlocked state.

[0017] Preferably, the line resources comprise the route resource, the side protection resource and the crossing resource.

[0018] Preferably, the hostility check is used to ensure that the locked state of the resource and the target of the upper line resource application are consistent.

[0020] More preferably, the locked state of the route resource comprises “locked in the uplink direction” and “locked in the downlink direction”; the locked state of the side protection resource comprises “locked in the positioning route”, “locked in the anti-positioning route”, “locked in the positioning conflict” and “locked in the anti-positioning conflict”; the locked state of the crossing resource comprises “locked in the route side” and “locked in the conflict side”.

[0021] The unlocked state of the route resource, the side protection resource and the crossing resource all comprise “unlocked”.

[0022] More preferably, the resource manager uses the “train unlocking point” to unlock each line resource in the locked state, wherein the “train unlocking point” is the position of the train minimum tail safety positioning extended by the rear sliding distance after setting.

[0023] More preferably, when the “train unlocking point” passes the route resource locked in the running direction of the train, the route resource is released.

[0024] When the “train unlocking point” passes a track section, the route resources upstream of the track section are all unlocked.

[0025] More preferably, when the train unlocking point passes the side protection resource of the first position of the turnout, the side protection resource is released; meanwhile, the side protection resource of the second position of the turnout which is in conflict with the side protection resource is also released.

[0026] More preferably, when the train unlocking point passes the second intersection resource associated with the crossover, the intersection resource is released; meanwhile, the first intersection resource which is in conflict with the intersection resource is also released.

[0044] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application.

[0045] The present embodiment relates to a track section management method based on line resource management, which comprises the following steps: Figure 1

[0046] In step A, the RMU regards the route handling command and the single switch locking command of the ATS and the resource application request of the train as line resource application. In step B, the RMU regards the route cancellation command, the route manual unlocking command, the single switch unlocking command of the ATS and the resource release request of the train as line resource release. The commands from the ATS and the resource requests from the train in the steps are external resource application or release requests in Figure 1 . Figure 2 Figure 3 Figure 1

[0047] In step B, the line resource application sets the corresponding path resource, side protection resource and crossing resource to the locked state after the hostile check. In step C, the line resource release sets the corresponding locked path resource, side protection resource and crossing resource to the unlocked state after the legality check. Figure 2 Figure 3 Figure 1 The internal resource in Figure 1 refers to the path resource, the side protection resource and the crossing resource.

[0048] The hostile check and the legality check are both to avoid locking or unlocking the wrong resource, so as to ensure that the locking or unlocking state of the resource and the target of the upper line resource application or line resource release are consistent.

[0049] The locking state of the path resource includes "locked in the uplink direction" and "locked in the downlink direction"; the locking state of the side protection resource includes "locked in the positioning path", "locked in the reverse positioning path", "locked in the positioning conflict" and "locked in the reverse positioning conflict"; the locking state of the crossing resource includes "locked in the path side" and "locked in the conflict side"; and the unlocking state of the above-mentioned resources all includes "unlocked".

[0050] In step C, when the range of a track section and the range of any line resource have intersection, it is said that the track section contains the line resource. If all the line resources contained by a track section are in the locked state, the track section is locked. If all the line resources contained by a track section are in the unlocked state, the track section is unlocked. ​​​​​​

[0051] Assume that the ATS orders 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, then the path resources are as follows: Figure 4 As shown. Figure 4 If the direction from the start point to the end point is upward, these path resources will now be in the "locked in the upward direction" state if they were previously in the "unlocked" state.

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

[0053] 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 "stroke" type cross resource a) and the second cross resource ( Figure 6 b) If these cross-connection resources were previously in the "unlocked" state, the second cross-connection resource of cross-connection 1 will now be in the "locked on the path side" state, and the first cross-connection resource of cross-connection 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 is safely positioned and then extends to the rear of the train to set the back sliding distance) to unlock the above resources.

[0056] When the "train unlocking point" passes through the path resource locked in this direction along the train's running direction, the path resource is released. Figure 4 In the example, if a train runs from its starting point to its destination in the upward direction, the path resources locked in the upward direction between the starting point and the destination will be unlocked after the train unlocking point passes the destination. More specifically, when the train unlocking point passes a track section, all path resources upstream of that track section will be unlocked.

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

[0058] The side protection resource locking and releasing principle of the turnout 1 in the position is the same as that in the reverse position.

[0059] In Figure 6 the second intersection resource is released. At the same time, the first intersection resource of the intersection 1 "locked in the conflict side" is also released because the conflict side resource is released.

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

[0061] In the above resource releasing process, if all the 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 the ATS sends a command to cancel the route, and the path between the start point and the end point is clear, and there is no train about to enter the area, the above-mentioned line resources will be immediately released, and all the track sections in them will be immediately unlocked.

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