Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit, and in particular to a method and device for evacuation protection of a trackside area, and a medium. BACKGROUND

[0002] In a full automatic train operation control system, if a train fails in an interval between two stations and passengers need to be evacuated, the passengers may walk near the track. At this time, if other trains are still running normally, the safety of the passengers will face great risks. In order to avoid the safety of personnel being harmed by other running trains, the zone controller (ZC) of the trackside should set protection according to the area where the personnel may walk, and the trains outside this area cannot enter, and the trains inside this area cannot continue to run.

[0003] After searching, the Chinese patent publication No. CN115447642A discloses an automatic protection method, device and medium for evacuation of a rail transit interval, specifically discloses that after the passenger activates the emergency handle, the on-board VOBC automatically sends an emergency evacuation request to the trackside zone controller ZC, the trackside zone controller ZC establishes an evacuation protection zone according to the evacuation train position, controls all CBTC trains in the evacuation protection zone to stop by emergency braking, and prohibits CBTC trains outside the evacuation protection zone from entering the activated evacuation protection zone.

[0004] Through analysis, the existing patent also proposes a method of activating the corresponding evacuation protection area according to the evacuation request of the train, but cannot solve the problem of how to send the request when the train fails to communicate with the trackside controller, and cannot solve the problem of the evacuation protection area spanning multiple area controllers.

[0005] In summary, if a train fails during operation, there may be situations where the doors are not opened, the train cannot communicate with the trackside controller, or the stopping area spans multiple area controllers and is difficult to coordinate. At this time, how to safely and efficiently evacuate the personnel is a problem to be solved. SUMMARY

[0006] The purpose of the present application is to overcome the defects of the prior art and provide a method and device for evacuation protection of a trackside area.

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

[0008] According to a first aspect of the present invention, an evacuation protection method for trackside area control is provided. The method first processes an evacuation bypass request or an evacuation activation request from an automatic train monitoring system (ATS) and a zone controller (ZC) through information interaction between the ATS. Secondly, an evacuation protection collaborative relationship across adjacent zone controllers is established through information interaction between adjacent ZCs. Finally, collaborative protection is performed by sending a notification to the interlocking system through the ZC.

[0009] As a preferred technical solution, the method specifically includes the following steps:

[0010] Step S1: The zone controller ZC sets the corresponding evacuation request area according to the evacuation bypass request sent by the automatic train monitoring system ATS, and determines whether to bypass the evacuation request from the train or the evacuation request from the adjacent ZC;

[0011] Step S2: The area controller sets the corresponding activated evacuation request area according to the evacuation activation request sent by the automatic train monitoring system;

[0012] Step S3: If the evacuation request area spans to an adjacent regional controller, the regional controller further sets a corresponding activated evacuation request area according to the evacuation request sent by the adjacent regional controller;

[0013] Step S4: The regional controller sets the corresponding evacuation protection area to an activated state according to the activated evacuation request area, and if the evacuation request area spans to other adjacent regional controllers, it also sends an evacuation request to the other adjacent regional controllers;

[0014] Step S5: The area controller notifies the corresponding interlocking protection area according to the activated evacuation protection area.

[0015] As a preferred technical solution, in step S1, if the regional controller receives an evacuation request area bypass request sent by the automatic train monitoring system, the evacuation request area will bypass the evacuation request from the train; if the regional controller receives an evacuation request area cancel bypass request sent by the automatic train monitoring system, the evacuation request area will no longer bypass the evacuation request from the train.

[0016] As a preferred technical solution, in step S1, if the area controller receives an evacuation bypass request from an adjacent area controller sent by the automatic train monitoring system, the adjacent area controller is evacuated and bypassed; if the area controller receives a cancellation evacuation bypass request from an adjacent area controller sent by the automatic train monitoring system, the adjacent area controller is not evacuated and bypassed.

[0017] As a preferred technical solution, in step S2, the evacuation activation request sent by the automatic train monitoring system to the area controller comes from an evacuation activation request message.

[0018] As a preferred technical solution, in steps S3 and S4, the evacuation request is transmitted between two adjacent area controllers via Boolean messages.

[0019] As a preferred technical solution, in step S4, after the evacuation protection area is activated, the movement authorization calculated by the regional controller for the train will not be able to enter the scope of the evacuation protection area. For the train already in the evacuation protection area, the regional controller will calculate an invalid movement authorization for it; at this point, the regional controller has completed the protection of the communication train.

[0020] As a preferred technical solution, in step S5, the zone controller notifies the interlocking protection of the corresponding zone through a binary code message; at this point, the zone controller and the interlocking system cooperate to complete the protection of non-communication trains.

[0021] According to a second 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 processor implements the method when executing the program.

[0022] According to a third aspect of the present invention, a computer-readable storage medium is provided, on which a computer program is stored, and when the program is executed by a processor, the method described above is implemented.

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

[0024] 1) The present invention supports evacuation protection areas that span ZC boundaries, thereby enabling evacuation requests to be transmitted between adjacent ZCs, expanding the evacuation protection range and freeing designers from being restricted by ZC boundaries when setting evacuation protection areas.

[0025] 2) The present invention supports direct activation of evacuation protection areas through ATS, solving the problem of how to activate evacuation protection areas when communication failure occurs between the train and ZC, ensuring that operators can control the corresponding areas in a timely manner;

[0026] 3) The present invention provides an evacuation request zone bypass mechanism and an adjacent zone controller evacuation bypass mechanism, making the operator more flexible in applying evacuation protection. In special circumstances, if the operator does not need the automatic evacuation protection measures, they can bypass them to avoid affecting other train operations, thus improving the availability of the entire system.

[0027] 4) The present invention provides a mechanism in which ZC activates the evacuation protection area and notifies the interlocking to provide collaborative protection for non-communication vehicles, solving the problem that ZC can only protect communication vehicles, making the evacuation protection mechanism more complete.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0032] like Figure 1 As shown, the evacuation protection method for trackside area control of the present invention specifically includes the following steps:

[0033] Step S1: The zone controller ZC sets the corresponding evacuation request area according to the evacuation bypass request sent by the automatic train monitoring system ATS, and determines whether to bypass the evacuation request from the train or the evacuation request from the adjacent ZC;

[0034] Step S2: The area controller sets the corresponding activated evacuation request area according to the evacuation activation request sent by the automatic train monitoring system;

[0035] Step S3: If the evacuation request area spans to an adjacent regional controller, the regional controller further sets a corresponding activated evacuation request area according to the evacuation request sent by the adjacent regional controller;

[0036] Step S4: The regional controller sets the corresponding evacuation protection area to an activated state according to the activated evacuation request area, and if the evacuation request area spans to other adjacent regional controllers, it also sends an evacuation request to the other adjacent regional controllers;

[0037] Step S5: The area controller notifies the corresponding interlocking protection area according to the activated evacuation protection area.

[0038] In step S1, if the regional controller receives an evacuation request area bypass request sent by the automatic train monitoring system, the evacuation request area will bypass the evacuation request from the train; if the regional controller receives an evacuation request area cancel bypass request sent by the automatic train monitoring system, the evacuation request area will no longer bypass the evacuation request from the train.

[0039] In step S1, if the zone controller receives an evacuation bypass request from an adjacent zone controller sent by the automatic train monitoring system, the adjacent zone controller is evacuated and bypassed; if the zone controller receives an evacuation bypass cancellation request from an adjacent zone controller sent by the automatic train monitoring system, the adjacent zone controller is not evacuated and bypassed.

[0040] In step S2, the evacuation activation request sent by the automatic train monitoring system to the zone controller is from the evacuation activation request message. In steps S3 and S4, the evacuation request is transmitted between two adjacent zone controllers via Boolean messages.

[0041] In step S4, after the evacuation protection zone is activated, the zone controller's calculated movement authorizations for trains will no longer be able to enter the evacuation protection zone. For trains already within the zone, the zone controller's calculated movement authorizations will be invalidated. At this point, the zone controller has completed protection for communicative trains. In step S5, the zone controller notifies the interlocking system of the corresponding protection zone via a binary code message. At this point, the zone controller and the interlocking system have collaboratively completed protection for non-communicative trains.

[0042] Compared with the existing technology, the present invention supports the evacuation protection area across the ZC boundary, thereby realizing the transmission of evacuation requests between adjacent ZCs and expanding the evacuation protection range; supports direct activation of the evacuation protection area through ATS, solving the problem of how to activate the evacuation protection area when the communication between the train and ZC fails; provides an evacuation request area bypass mechanism and an adjacent area controller evacuation bypass mechanism, making the operation personnel more flexible in applying evacuation protection; provides a mechanism for notifying interlocking after the ZC activates the evacuation protection area, thereby providing collaborative protection for non-communication vehicles, etc.

[0043] like Figure 2 As shown, the evacuation protection of a single zone controller includes the following steps:

[0044] In step 201, the tracks corresponding to Platform 1 and Platform 2 are divided into Evacuation Protection Zone 1 and Evacuation Protection Zone 3, respectively, while all tracks between the two stations are divided into Evacuation Protection Zone 2. Furthermore, only the tracks between the two stations are defined as Evacuation Request Zone 1. This Evacuation Request Zone 1 is simultaneously associated with Evacuation Protection Zones 1, 2, and 3. This means that if a train breaks down in the section between the two stations and passengers need to be evacuated, since passengers may walk to Platform 1 or Platform 2, ZC1 will set all areas of the two platforms and the section as protection zones, thereby preventing trains from moving within them and preventing trains from entering them.

[0045] In step 202 , if the train fails and cannot communicate with ZC1 , the operator may send an evacuation activation request message to ZC1 via the ATS, indicating that the evacuation request area 1 needs to be activated.

[0046] In step 203, if the train is still communicating with ZC1, it can proactively send an evacuation request to ZC1. This request, along with the safety location information, is sent along with the location message. Upon receiving the train's evacuation request, ZC1 calculates that its safety location intersects with evacuation request area 1 and prepares to activate evacuation request area 1. However, it also needs to query the bypass status of evacuation request area 1.

[0047] The operator can send an evacuation request area bypass message to ZC1 via ATS at any time according to the actual situation, indicating that the evacuation request area 1 needs to be bypassed. After receiving the message, ZC1 will consider that the evacuation request area 1 is bypassed.

[0048] In addition, the operator can also send an evacuation request area bypass cancellation message to ZC1 through ATS at any time, indicating the need to cancel the bypass evacuation request area 1. After receiving the message, ZC1 will consider that the evacuation request area 1 has not been bypassed.

[0049] Through the above operations, if ZC1 finds that the evacuation request area 1 is not bypassed, the evacuation request area 1 will be activated eventually.

[0050] Step 204, due to Figure 2 The scenario shown only involves evacuation protection within ZC1, so there is no evacuation request from the adjacent ZC and this step will be ignored.

[0051] Step 205: If the evacuation request area 1 is finally activated by the ATS or train request, ZC1 sets the evacuation request area 1 to the activated state.

[0052] Step 206, as described in step 201, the evacuation request area 1 will be associated with the evacuation protection areas 1, 2 and 3 at the same time. After the evacuation request area 1 is activated, ZC1 will set the evacuation protection areas 1, 2 and 3 to the activated state and notify the interlocking protection of the evacuation protection areas 1, 2 and 3. At this time, for trains within the range of evacuation protection areas 1, 2 and 3, ZC1 will calculate invalid movement authorizations for them, and then send special control messages, and the trains should take emergency braking. For trains outside the range of evacuation protection areas 1, 2 and 3, the end points of the movement authorizations calculated by ZC1 for them will be at the boundaries of the aforementioned ranges, and the trains will not be able to enter these areas. In addition, after receiving the notification from ZC, the interlocking will restrict non-communication vehicles from entering or operating in these areas. So far, the activation method of the evacuation protection areas has been explained, and in these areas, there will be no moving trains that may endanger the personal safety of evacuated passengers.

[0053] Steps 207 to 208, after the evacuation is completed, the operator can send three evacuation cancellation request messages to ZC1 through ATS, indicating the need to cancel the activated evacuation protection areas 1, 2 and 3 respectively. After receiving these messages, ZC1 sets the evacuation protection areas 1, 2 and 3 to the non-activated state, and the movement authority calculated for the train will no longer be affected by these areas, and the operation of all trains on the line will return to normal. Thus, the evacuation protection area cancellation method is illustrated.

[0054] As shown in Figure 3 , the coordinated evacuation protection of multiple area controllers includes the following steps:

[0055] Step 301, similar to Figure 2 , the tracks corresponding to platform 1 and platform 2 will be divided into evacuation protection areas 1 and 3 respectively, and the evacuation protection area 2 between the two stations will be divided into evacuation protection areas 21 and 22 because it crosses the boundary of ZC1 and ZC2. Similarly, the evacuation request area 1 is also divided into evacuation request areas 11 and 12. ZC1 manages the evacuation request area 11, the evacuation protection areas 1 and 21, and the evacuation request area 11 is associated with the evacuation protection areas 1 and 21 at the same time. ZC2 manages the evacuation request area 12, the evacuation protection areas 22 and 3, and the evacuation request area 12 is associated with the evacuation protection areas 22 and 3 at the same time. When a train needs to evacuate passengers due to a failure in the section between the two stations, the protection target of the system does not change, i.e. the evacuation protection areas 1, 21, 22 and 3 should also be set to the activated state, so there needs to be a coordinated activation method for the evacuation protection areas between ZC1 and ZC2.

[0056] Steps 302 to 303, if the train evacuates near the evacuation request area 11 within ZC1, the processing method of ZC1 and Figure 2 the example steps are exactly the same.

[0057] Step 304, after the evacuation request area 11 is finally activated, ZC1 will send an activation request for the evacuation request area 12 to ZC2 through a Boolean message. When ZC2 receives the message, it will first query the evacuation bypass state of the adjacent ZC1.

[0058] The operator can send an adjacent ZC evacuation bypass message to ZC2 through ATS at any time according to the actual situation, indicating the need to evacuate the adjacent ZC1. After receiving the message, ZC2 will consider that the adjacent ZC1 is evacuated.

[0059] In addition, the operator can also send an adjacent ZC evacuation bypass cancellation message to ZC2 through ATS at any time, indicating the need to cancel the evacuation bypass of the adjacent ZC1. After receiving the message, ZC2 will consider that the adjacent ZC1 is not evacuated.

[0060] Through the above operations, if ZC2 finds that the adjacent ZC1 is not evacuated and bypassed, the evacuation request area 12 will be activated eventually.

[0061] Step 305 : ZC1 sets the evacuation request area 11 to an active state, and ZC2 sets the evacuation request area 12 to an active state.

[0062] Step 306: As described in step 301, ZC1 sets the evacuation protection areas 1 and 21 to the activated state and notifies the interlocking protection to evacuate the protection areas 1 and 21. ZC2 sets the evacuation protection areas 22 and 3 to the activated state and notifies the interlocking protection to evacuate the protection areas 22 and 3. So far, the method of coordinated activation of evacuation protection areas between adjacent ZCs has been explained. Figure 2 and Figure 3 The example scenario will provide exactly the same evacuation protection.

[0063] From step 307 to step 308, after the passenger evacuation is complete, the operator can send two evacuation cancellation request messages to ZC1 through the ATS, indicating that the activation of evacuation protection zones 1 and 21 needs to be canceled. Then, two evacuation cancellation request messages are sent to ZC2, indicating that the activation of evacuation protection zones 22 and 3 needs to be canceled. At this point, the evacuation protection across multiple ZCs is also completely canceled.
