Description

Technical Field

[0001] The invention relates to a rail transit signal system, and in particular to a method, a device and a medium for preventing a signal machine from being erroneously and rapidly unlocked. Background Art

[0002] For urban rail transit systems, if there is a switch within a certain distance behind the signal, in order to prevent the train from squeezing the switch or derailing, a protection section will be set up at a certain distance behind the signal. After the approach to the signal with the signal as the terminal protection is established, the protection section of the signal will be established, and then all the switches within the protection section will be locked in the specified position and cannot be moved, ensuring the safety of the train.

[0003] In order to take into account the safety and efficiency of the entire urban rail transit signal system, an area for quick unlocking is set in front of the signal in the signal protection section:

[0004] 1) If the train under safety protection stops within the quick unlocking area, the onboard controller sends the unlocking information to the trackside controller, and the signal protection section will be quickly unlocked, and the corresponding turnout can be moved to prepare for the next train route arrangement.

[0005] 2) If the train does not stop within the quick unlocking area, the onboard controller will not send unlocking information to the trackside controller, and the protection section of the signal will not be able to be unlocked quickly. It will take a long time to unlock, affecting the arrangement of subsequent routes, especially in the reversing area, where the turnout needs to move frequently. If it is locked for a long time, the reversing efficiency will be greatly reduced, which will in turn affect the operating efficiency of the entire line.

[0006] Regarding the area range of the signal quick unlocking mentioned above, in order to prevent two trains from getting too close, the rear train mistakenly unlocks the signal protection section established for the front train, resulting in switch unlocking and unexpected switch movement, and the risk of the front train being squeezed or derailed, the distance of the quick unlocking area is set to be relatively short, which can ensure that only one train can stop in the quick unlocking area, thereby ensuring driving safety.

[0007] Under normal circumstances, this function can work effectively and normally, but in some special cases, quick unlocking failure may occur. For example, there are two types of trains in the line, long trains and short trains, and their terminal turnaround platform parking points are different. The parking point of the long train is close to the signal, and the parking point of the short train is in the middle of the platform. After the short train stops at the platform, the train is not within the quick unlocking area of ​​the signal, resulting in the protection section of the signal failing to be quickly unlocked, affecting the turnaround efficiency of the entire line. If the quick unlocking area is enlarged to include the location of the short train parking point, the rear train will mistakenly unlock the signal protection section of the front train, which poses a safety risk.

[0008] For trains of different lengths, how to achieve quick unlocking while ensuring driving safety becomes a technical problem that needs to be solved. Summary of the invention

[0009] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a method, device and medium for preventing the signal light from being unlocked quickly by mistake, which can both quickly unlock the signal light and ensure driving safety.

[0010] The purpose of the present invention can be achieved by the following technical solutions:

[0011] According to a first aspect of the present invention, a method for preventing a signal from being unlocked quickly by mistake is provided. The method designs an "exclusive zone" to prevent incorrect rapid unlocking. The "exclusive zone" covers all parking points of marshalled trains of different lengths. Only one train is allowed to enter the "exclusive zone".

[0012] As a preferred technical solution, the length of the "exclusive area" for preventing erroneous quick unlocking includes the length of the quick unlocking area of ​​the signal protection section plus the length of the custom area.

[0013] As a preferred technical solution, the quick unlocking area of ​​the signal protection section is extended to include all the parking positions of the train sets according to the lengths of the different train sets on the line and the corresponding parking positions.

[0014] As a preferred technical solution, the quick unlocking area of ​​the signal protection section starts from the beginning of the section corresponding to the signal and covers all marshaling train stopping points of different lengths.

[0015] As a preferred technical solution, the length of the custom area is used to ensure that no rear vehicle will enter the quick unlocking area of ​​the front vehicle.

[0016] As a preferred technical solution, the "exclusive area" for preventing erroneous quick unlocking starts from the beginning of the section corresponding to the signal, at least covers the entire area of ​​the corresponding quick unlocking area, and increases the length of the custom area.

[0017] As a preferred technical solution, after the "exclusive area" for preventing erroneous quick unlocking is set, the length of the custom area is adjusted to meet the requirement of the running interval.

[0018] As a preferred technical solution, if there is already a train occupying the "exclusive area" that prevents erroneous quick unlocking, the subsequent train must stop outside the "exclusive area" until all trains in the "exclusive area" have left and there are no trains occupying the area, and only then can the subsequent train enter the "exclusive area".

[0019] As a preferred technical solution, if a train occupies the "exclusive area" for preventing erroneous quick unlocking, the rear train uses the boundary of the exclusive area as a restriction point and stops outside the exclusive area.

[0020] As a preferred technical solution, the signal system determines whether the train stop position is in the quick unlocking area. If so, the signal system sends a quick unlocking command and the signal protection area performs the quick unlocking process. Otherwise, no quick unlocking command is sent.

[0021] According to a second aspect of the present invention, there is provided an electronic device, 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.

[0022] 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.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] 1) The present invention solves the problem that different marshaling trains cannot simultaneously realize the signal protection section quick unlocking function, and is compatible with the quick unlocking requirements of marshaling trains of different lengths;

[0025] 2) The present invention designs a method specifically for preventing the signal from being unlocked quickly by mistake, thereby solving the safety risks caused by possible mistaken unlocking;

[0026] 3) The present invention takes into account both the efficiency problem of fast unlocking and the security problem of erroneous unlocking, achieving both and well solving the problems of the original solution. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 A schematic diagram of the quick unlocking area of ​​the present invention and the "exclusive area" for preventing erroneous quick unlocking;

[0028] Figure 2 The figure is a flow chart of the train determining the exclusive area and quickly unlocking the exclusive area according to the present invention. DETAILED DESCRIPTION

[0029] 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.

[0030] The present invention discloses a method for preventing a signal machine from being unlocked quickly by mistake. The method designs an "exclusive zone" for preventing the signal machine from being unlocked quickly by mistake. The "exclusive zone" covers all parking spots of marshaled trains of different lengths. Only one train is allowed to enter the "exclusive zone".

[0031] The design of the quick unlocking area in the signal protection section: according to the length of different train sets on the line and the corresponding parking points, the original smaller quick unlocking area is extended to include the parking points of all train sets, such as the entire platform area, to ensure that no matter what train set stops at its respective parking point, the signal can be quickly unlocked.

[0032] Design of the signal protection section to prevent the rear vehicle from mistakenly unlocking the front vehicle: Based on the quick unlocking area of ​​the entire signal protection section, add a custom distance (this distance can be defined according to the actual situation) and define this range as an "exclusive area" to prevent mistaken quick unlocking. At the same time, it is necessary to consider whether the specified operating interval can be met after the "exclusive area" is set. If it affects the operating interval, the above custom distance needs to be adjusted until the operating interval is met.

[0033] The design logic of the "exclusive area" prevents incorrect and quick unlocking: only one train is allowed to enter the exclusive area. If there is already a train occupying the area, the subsequent train needs to stop outside the area until all trains in the area have left and there are no trains occupying the area. Only then can the subsequent train enter the exclusive area.

[0034] The above design can simultaneously meet the requirement of trains quickly unlocking the signal protection area, and solve the safety problem of the rear train mistakenly unlocking the signal protection area of ​​the front train.

[0035] like Figure 1 As shown in the figure, the settings of the quick unlock area and the "exclusive area" to prevent incorrect quick unlock are explained in detail:

[0036] 1. The quick unlocking area starts from the beginning of the section corresponding to the signal and covers all train stop points 1 and 2 of different lengths, ensuring that trains of different marshaling groups can quickly unlock the signal protection section when they stop at different stop points;

[0037] 2. The "exclusive zone" to prevent incorrect quick unlocking starts from the beginning of the section corresponding to the signal and at least covers the entire area of ​​the corresponding quick unlocking area. A custom length can be added to ensure that no rear vehicle enters the quick unlocking area of ​​the front vehicle;

[0038] 3. After the "exclusive zone" is set to prevent erroneous quick unlocking, the running interval of the train needs to be calculated to ensure that the setting of this area will not affect the operating interval. If there is an impact, the above custom length can be adjusted.

[0039] like Figure 2 As shown in the figure, the simplified flow chart of train judgment of exclusive area and quick unlocking is explained:

[0040] Step 1: The train onboard controller operates according to the received authorized endpoint

[0041] Step 2: The signal system searches for an "exclusive zone" within the authorized end point distance range to prevent incorrect quick unlocking. If yes, proceed to step 2.1; if no, proceed to step 3.

[0042] Step 2.1: If the result of step 2 is "yes", continue to determine whether there are other trains occupying the exclusive area. If "yes", proceed to step 2.2; if "no", proceed to step 3;

[0043] Step 2.2, if the result of step 2.1 is "yes", the train uses the boundary of the exclusive area as a restriction point, stops outside the exclusive area, and continuously checks whether other vehicles are occupying the exclusive area;

[0044] Step 3: If the result of step 2 or step 2.1 is "no", the signal system continues to search whether there is a stopping point for the train set within the authorized end point range. If "yes", it goes to step 4; if "no", it goes to step 1;

[0045] Step 4: If the result of step 3 is "yes", the train stops precisely at the stop point of the train set;

[0046] Step 5, the signal system determines whether the train stop position is in the quick unlocking area, if "yes", go to step 5.1, if "no", go to step 5.2;

[0047] Step 5.1, if the result of step 5 is "yes", the signal system sends a quick unlock command, and the signal protection area performs a quick unlock process;

[0048] Step 5.2: If the judgment result of step 5 is "No", the signal system does not send a quick unlock command.
