Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit, and in particular to a protection route delay-unlocking countdown processing method and system for train tracking. BACKGROUND

[0002] The protection route is a protection area set for train operation safety, and can be released for use by other trains only when the train no longer needs it. When the train reaches the stop section in front of the protection route, the delay-unlocking countdown will be triggered. During the countdown, if the train stops, the train-mounted or zone controller (ZC) subsystem will transmit the stop information to the computer-based interlocking (CI) subsystem to unlock the route and end the countdown. If no stop information is received, the CI subsystem will unlock the route after the countdown ends. Alternatively, the countdown will be cleared when the train clears the stop section.

[0003] The existing protection route delay-unlocking countdown method has basic functions, but has obvious defects in the train tracking operation scenario. When two trains occupy the stop section at the same time, after the front train clears the stop section, the system cannot accurately clear the protection route delay-unlocking countdown for the front train, nor can it correctly set a new delay-unlocking countdown for the rear train, because the stop section is still occupied by the rear train. If the rear train mistakenly uses the countdown of the front train, the protection route of the rear train will be unlocked prematurely, which will affect the normal stop of the rear train and ultimately adversely affect the operation efficiency and safety.

[0004] Therefore, there is an urgent need for a protection route delay-unlocking countdown processing method and system for train tracking to solve the above problems. SUMMARY

Obviously, the drawings in the following description are some embodiments of the present application, and those skilled in the art can obtain other drawings according to these drawings without any creative effort.

[0018] Figure 1A flowchart of a protection route delay unlocking countdown processing method for train tracking is provided in the present application.

Figure 3 A structure diagram of an electronic device is provided in the present application. DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0020] In the existing urban rail transit control system, the CI subsystem can unlock the protection route according to the stop information of the on-board automatic train protection (ATP) subsystem or the ZC subsystem, or the protection route delay unlocking information. If the CI subsystem does not receive the stop information, the protection route can be unlocked when the delay unlocking countdown ends. In train tracking, the clearing time of the front train protection route delay unlocking countdown and the setting time of the rear train protection route delay unlocking countdown remain consistent with those in the case of no train tracking, which greatly affects the operation efficiency of the unmanned line.

[0021] The protection route is a protection area occupied for the safety of train operation. Only when the train no longer needs the protection route, the protection route can be released for the operation of other trains. When the train runs to the stop section in front of the protection route, the protection route delay unlocking countdown is triggered. During the unlocking countdown, if the train stops, the ATP subsystem or the ZC subsystem sends the stop information to the CI subsystem, and the CI subsystem can unlock the protection route and end the countdown according to the stop information. If the CI subsystem does not receive the stop information during the countdown, the CI subsystem can unlock the protection route when the countdown ends. If the train clears the stop section, the protection route delay unlocking countdown is directly cleared at this time.

[0022] Although the existing method can realize the protection route delay unlocking function, the stop section may be occupied by two trains simultaneously in train tracking. When the front train clears the stop section, the stop section is still occupied, which cannot correctly clear the protection route delay unlocking countdown for the front train, nor correctly set the protection route delay unlocking countdown for the rear train. If the rear train incorrectly uses the countdown of the front train, the protection route of the rear train may be unlocked in advance, which affects the stop of the rear train and further affects the operation efficiency.

[0023] In view of the problems in the prior art, the application provides a protection route delay unlocking countdown processing method for train tracking, which can correctly set and clear the protection route delay unlocking countdown for front and rear trains, and further correctly lock the protection route for the rear train, so that the correct locking of the protection route can guarantee the train operation safety and the stopping efficiency.

[0024] Figure 1 A flowchart of the protection route delay unlocking countdown processing method for train tracking provided by the application is shown in Figure 1 The application provides a protection route delay unlocking countdown processing method for train tracking, which comprises the following steps: In step 101, the protection route delay unlocking time length corresponding to the target train is determined according to the train type of the target train.

[0025] In the application, according to the train type of the target train, for example, whether it is a continuous train control (CTC) type or a non-CTC type train (such as a non-equipped train, including a fault train, a non-position reporting train, and a position reporting but non-upgraded train), the protection route delay unlocking time length corresponding to the train type is determined. In the application, this time length is determined according to the characteristics, running speed, safety requirements and other factors of the train to ensure that the train has enough time to perform necessary operations in the stopping section, and at the same time, to ensure the safety of train operation.

[0026] In step 102, when it is determined that the stopping section has been converted to an occupied state, or the stopping section is in an occupied state and the protection route in front of the target train is in an available state, the protection route delay unlocking countdown function of the target train is triggered based on the protection route delay unlocking time length.

[0027] In the application, when it is determined that the stopping section has been converted to an occupied state or is occupied, and the protection route is in an available state, the protection route delay unlocking countdown function of the protection route will be triggered based on the protection route delay unlocking time length. When it is determined that the protection route is in an available state, it means that the protection route has been prepared for the target train and can be used at any time.

[0028] In step 103, when it is determined that the protection route delay unlocking countdown function is running at the current time and has not reached the end of the countdown, if the stopping section at the current time is clear or the stopping section and the continuation section of the stopping section are both in an occupied state, a clear operation is performed on the protection route delay unlocking countdown function.

[0029] In the present application, when it is determined that the protection route delay unlocking countdown function is running at the current time, but has not yet reached the state of countdown end, if the stable section has been cleared (i.e. no train occupies), or the stable section and the continuation section of the stable section are in the state of occupation at the same time, the zero clearing operation of the protection route delay unlocking countdown function will be performed. The purpose of this step is to ensure that when the stable section is occupied again, the correct delay unlocking countdown can be triggered. If not cleared, it may cause the countdown time to be inaccurate, thereby affecting the safety and efficiency of subsequent train operation. Through the zero clearing operation, it can ensure that when the stable section is occupied again, the correct delay unlocking countdown can be recalculated and triggered based on the new train type and state. By reasonably setting and triggering the protection route delay unlocking countdown function, and timely zero clearing operation, the safety and efficiency of train operation are ensured.

[0030] The present application provides a protection route delay unlocking countdown processing method for train tracking, which sets the protection route delay unlocking countdown start and zero clearing time, ensures the safety of train operation, and improves the efficiency of line operation.

[0031] On the basis of the above-mentioned embodiments, the method further comprises: When it is determined that the protection route delay unlocking countdown function is running at the current time, and has not yet reached the state of countdown end, if the stable section at the current time is cleared, or the stable section and the continuation section of the stable section are in the state of occupation at the same time (i.e. the train is in the process of leaving the stable section), the zero clearing operation of the protection route delay unlocking countdown function is performed.

[0032] In the present application, the protection route delay unlocking countdown function is used as a safety mechanism to ensure that the train has enough time to perform necessary operations in the stable section, and automatically unlocks the route after confirming safety, so that the subsequent train can use it. The stable section is a specific area where the train stops and performs related operations. The continuation section of the stable section refers to the area directly connected to the stable section and can be used for further operation or preparation of leaving.

[0033] Specifically, in the present application, when it is determined that the protection route delay unlocking countdown function is running, and has not yet reached the state of countdown end, it indicates that the target train is currently still operating in the stable section or its vicinity, and the protection route has not been automatically unlocked. At the same time, it is also detected that the stable section and its continuation section are in the state of occupation, in which case the zero clearing operation of the protection route delay unlocking countdown function is performed, indicating that the previous countdown will be cancelled, and the protection route will not be automatically unlocked as planned. The purpose of the zero clearing operation may be to re-evaluate the current situation and ensure that the protection route is correctly locked after confirming safety, to ensure the safety and efficiency of train operation.

[0034] On the basis of the above-mentioned embodiments, the method further comprises: determining the train type of the target train, and if the train type is continuous train control type, generating the protection route delay unlocking time length corresponding to the target train of the continuous train control type; if the train type is non-continuous train control type, generating the protection route delay unlocking time length corresponding to the target train of the non-continuous train control type.

[0035] In the present application, first, the train type of the target train is determined, if the target train is continuous train control type, a protection route delay unlocking time length corresponding to the train of this type is generated, which can be determined based on the characteristics of the continuous train control system, the speed of the train, the length and complexity of the stable section, and safety requirements and other factors.

[0036] If the target train is non-continuous train control type, a protection route delay unlocking time length corresponding to the non-continuous train control type is generated, and similarly, this time length also takes into account the characteristics of the non-continuous train control system to ensure the safe stopping and route unlocking of the train.

[0037] On the basis of the above-mentioned embodiments, the method further comprises: if the protection route delay unlocking time length is zero, the stable section is in the occupied state or has been in the occupied state, and the protection route is in the available state, triggering the protection route delay unlocking countdown function based on the protection route delay unlocking time length.

[0038] In the present application, when the protection route delay unlocking time length is zero, it indicates that the target train has triggered the protection route delay unlocking countdown before, and the countdown has ended, at this time, the target train is no longer in the countdown state of the protection route delay unlocking. At the same time, the stable section has been in or converted to the occupied state, at this time, the protection route in front of the target train is in the available state, indicating that the protection route in front of the target train (i.e. the path of the train) is available in both physically and logically, without obstacles or locked state to prevent the target train from advancing.

[0039] Further, in the case where all the above conditions are met, the protection route delay unlocking countdown function of the target train is triggered according to the protection route delay unlocking time length. The purpose of triggering the countdown function is to ensure that there is enough time to perform necessary preparations and checks before the target train can safely enter the stopping section, and to provide a clear and predictable time window for the target train to enter the section.

[0040] On the basis of the above embodiment, the method further comprises: When the countdown of the protection route delay unlocking countdown function has ended, the unlocking operation of the protection route is triggered.

[0041] In the present application, when the countdown of the protection route delay unlocking countdown function is in the ending state, it is determined that the countdown function has met the ending condition, which indicates that the train has completed all necessary operations in the stopping section and safety has been ensured, so the route can be safely unlocked. After determining that the unlocking condition is met, the unlocking operation of the protection route is triggered. Through the unlocking operation, the previously locked or occupied route can be released, so that the train can safely enter the route and prepare for the target train to leave the stopping section and continue to travel.

[0042] On the basis of the above embodiment, the method further comprises: After receiving the stopping information sent by the on-board train automatic protection subsystem or the regional controller subsystem, the protection route delay unlocking countdown function meets the ending condition and triggers the unlocking operation of the protection route.

[0043] In the present application, after receiving the stopping information, it is first confirmed that the train has stopped safely. Then, the protection route delay unlocking countdown function meets the ending condition. In the present application, the ending condition is no longer simply the end of the countdown, but is based on the fact that the train has stopped, so even if the countdown may not have completely ended, as long as the train has stopped, it can be determined that the purpose of the protection route delay unlocking has been achieved.

[0044] Further, after determining that the ending condition is met, the unlocking operation of the protection route is triggered, so that the train can safely enter the route.

[0045] The present application confirms that the protection route delay unlocking countdown function meets the ending condition based on the stopping information, and then triggers the unlocking operation of the protection route, to ensure the safety and efficiency of train operation, and to respond more flexibly to the actual state of the train.

[0046] In an embodiment, the protection route delay unlocking processing method for train tracking provided by the present application is described as a whole, and the specific process is as follows: When the current train runs to the stopping section, the protection route delay unlocking countdown is started, and when the current train occupies the stopping section and the continuation section of the stopping section, the protection route delay unlocking countdown is cleared; when the rear train protection route is valid and the stopping section is occupied, the protection route delay unlocking countdown is started, and when the rear train clears the stopping section or simultaneously occupies the stopping section and the continuation section of the stopping section, the protection route delay unlocking countdown is cleared.

[0047] In the embodiment, if the train is a CTC train, the CTC train protection route delay unlocking time is used for countdown; if the train is a non-CTC train, the non-CTC train protection route delay unlocking time is used for countdown.

[0048] Further, if the stopping information sent by the ATP subsystem or the ZC subsystem is obtained during the delay unlocking countdown, and the protection route is idle, the protection route is immediately unlocked and the countdown is ended; if the delay unlocking countdown reaches the end value and the protection route is idle, the protection route is immediately unlocked and the end value is maintained.
