[0043] The core of the present invention is to provide a method, device, equipment and computer-readable storage medium for confirming the protection section of a train route. When a train enters a target route, it can obtain the emergency braking trigger speed of each protection section included in the target route for the train, and use the protection section with the smallest emergency braking trigger speed as the target protection section to be entered. In this way, the train theoretically does not need to know the information of the only currently open protection section of the target route, which can reduce the layout cost of dynamic beacons and thus reduce the cost of trackside equipment.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 making creative efforts shall fall within the scope of protection of the present invention.

[0045] Please refer to FIG1 , which is a flow chart of a method for confirming a protected section of a train route provided by the present invention. The method for confirming a protected section of a train route is applied to a controller on a train, and includes:

[0046] S101: When entering a target route, obtaining the emergency braking trigger speed of each protection section included in the target route for the train;

[0047] Specifically, taking into account the technical problems in the above background technology, and taking into account that different emergency braking trigger speeds are set for the train in each protection section included in the target route, the emergency braking trigger speed is that the speed threshold that can trigger the train to generate emergency braking in order to prevent the train from having an accident. In order to ensure safety, the train speed should be avoided as much as possible to exceed the emergency braking trigger speed. If the train can control the speed of the train according to the minimum of the emergency braking trigger speeds of the train in each protection section included in the target route when traveling along the target route, then no matter which protection section the train enters, emergency braking will not be triggered. Therefore, based on this idea, in an embodiment of the present invention, when the train is traveling along the target route, the train speed is controlled according to the minimum emergency braking trigger speed of the protection sections included in the target route. Therefore, in this step, the emergency braking trigger speed of the train in each protection section included in the target route can be obtained when entering the target route.

[0048] The present invention can be applied to a variety of different control systems, and the embodiments of the present invention are not limited here.

[0049] Specifically, there are many ways to obtain the emergency braking trigger speed. For example, it can be obtained by querying the emergency braking trigger speed of each protection section of each approach, or by calculating it through relevant parameters, or by input by staff, etc. The embodiments of the present invention are not limited here.

[0050] S102: The minimum emergency braking trigger speed is used as the target emergency braking trigger speed, and the protection zone to which the target emergency braking trigger speed belongs is used as the target protection zone for the train to enter, so as to control the speed of the train according to the target emergency braking trigger speed.

[0051] Specifically, after obtaining the emergency braking trigger speeds of each protection section of the target route, based on the above idea, the minimum emergency braking trigger speed can be used as the target emergency braking trigger speed, so as to serve as the data basis for subsequent steps.

[0052] Specifically, after selecting the target emergency braking trigger speed, the train speed can be controlled according to the target emergency braking trigger speed. The purpose is to control the train to travel in a speed range below the target emergency braking trigger speed to prevent the emergency braking from being triggered during travel in the protection section, thereby causing safety accidents.

[0053] Specifically, beacons are the basic equipment for CBTC (Communication Based Train Control System) to achieve train positioning, and dynamic beacons are key equipment to support point-level train operation. Compared with European beacons, American beacons are cheaper, and are an ideal and economical choice, especially for trams or urban railways that do not require high train tracking intervals, operate at a point level, and transmit a small amount of information. American dynamic beacons are connected to signal machines through hard-wired circuits, and the corresponding American dynamic beacons are activated when the interlocking system drives the signal machine to the permissive state. When there are multiple routes corresponding to the signal machine at the beginning of the route, American dynamic beacons need to be added at the same location. When the same route has multiple protection sections, American dynamic beacons also need to be added at the same location. The deployment of a large number of American dynamic beacons requires a high cost.

[0054] The present invention provides a method for confirming the protection section of a train route. Considering that if the train controls its speed according to the minimum emergency braking trigger speed among the protection sections of the target route, driving safety can be guaranteed no matter which protection section is open in the target route, the train in the present invention can obtain the emergency braking trigger speeds of the various protection sections included in the target route for the train when entering the target route, and use the minimum emergency braking trigger speed as the target emergency braking trigger speed, and use the protection section to which the target emergency braking trigger speed belongs as the target protection section to be entered. In this way, the train theoretically does not need to know the information of the only currently open protection section of the target route, which can reduce the layout cost of dynamic beacons and thus reduce the cost of trackside equipment.

[0055] Based on the above embodiment:

[0056] As a preferred embodiment, obtaining the emergency braking trigger speed of each protection section included in the target route for the train includes:

[0057] Obtain the turnout speed limit information of each protection section included in the target route and the track length information of the section divided by the turnout;

[0058] Based on the train's braking acceleration, the switch speed limit information of each protection section, and the section track length information, the emergency braking trigger speed of each protection section of the target route for the train is determined.

[0059] Specifically, considering that the emergency braking trigger speed of the train in the protection section is correlated with the braking acceleration of the train, the speed limit information of the switches within the protection section, and the length information of the tracks in each section, in an embodiment of the present invention, the switch speed limit information of each protection section included in the target route and the section track length information based on the switch division can be first obtained, and then based on the braking acceleration of the train, the switch speed limit information of each protection section, and the section track length information, the emergency braking trigger speed of the train in each protection section of the target route can be determined. The accuracy of the acquired emergency braking trigger speed of the train in each protection section can be improved through real-time calculation.

[0060] As a preferred embodiment, based on the train's braking acceleration, the switch speed limit information of each protection section, and the section track length information, determining the emergency braking trigger speed of each protection section of the target route for the train includes:

[0061] Based on the train's braking acceleration, the switch speed limit information for each protection section, and the section track length information, the emergency braking trigger speed for each protection section of the target route is determined using a preset emergency braking trigger speed calculation formula;

[0062] The calculation formula for the emergency brake trigger speed includes:

[0063] Among them, V Overlap is the emergency braking trigger speed of the protection section, min() is used to get the minimum value in the brackets, a is the braking acceleration of the train, S XY is the total length of the track in the protection section, S PQ V is the track length from the speed limit section P to point Q of the turnout Q in reverse position, PQ is the lateral static speed limit of turnout Q.

[0064] Specifically, in order to determine the emergency braking trigger speed of each protection section more efficiently and accurately, an emergency braking trigger speed calculation formula is pre-set in the embodiment of the present invention. Then, based on the braking acceleration of the train, the switch speed limit information of each protection section and the section track length information, the emergency braking trigger speed of each protection section of the target route for the train can be determined through the preset emergency braking trigger speed calculation formula.

[0065] To better illustrate the embodiment of the present invention, please refer to FIG2 , which is a schematic diagram of the structure of a protection zone provided by the present invention. In FIG1 , the station approach from signal S2 to signal S6 includes three protection zones, namely:

[0066] Overlap (protection section) 1: physical section of T6 located by turnout 1;

[0067] Overlap2: The protection section is formed by combining the physical section T6 through the inversion of turnout 1 and the physical section T8 through the positioning of turnout 2 and turnout 3;

[0068] Overlap3: The protection section is formed by combining the physical section T6 through the reversal of turnout 1, the physical section T8 through the reversal of turnout 2, and the physical section T7 through the reversal of turnout 6.

[0069] When the S2 signal is open and the train passes the dynamic beacon VB2, the ATP (Automatic Train Protection) needs to update the train's authorized movement end point according to the open route. The three protection sections correspond to the end points of three switches with different speed limits and lengths. To ensure the safety of train operation, the protection section with the strictest speed limit conditions must be taken as the default protection section of the route. 1-6 in Figure 2 are all turnouts, and AG are various points on the track, which are used to distinguish different track sections. T6 is the physical section through the reverse position of turnout 1, T7 is the physical section through the reverse position of turnout 6, and T8 is the physical section through the reverse position of turnout 2.

[0070] Assume that the lateral static speed limit of turnout 1 is V1, the lateral static speed limit of turnout 2 is V2, and the approach terminal emergency braking trigger speeds corresponding to the three protection sections are V Overlap1 、V Overlap2 、V Overlap3 :

[0071] The default protection zone to which the target emergency braking trigger speed belongs should be the protection zone with the minimum emergency braking trigger speed among the three protection zones, i.e. min(V Overlap1 ,V Overlap2 ,V Overlap3 ) corresponding protection zone.

[0072] A certain project a=1.1m / s 2 , S CB =52.22m, S CE =44.84m, S ED =71.22m, S EG =71.47m, turnout 1 and turnout 2 are both turnout No. 9, V1=V2=35km / h, the default protection zone is: min(V Overlap1 ,V Overlap2 ,V Overlap3)=min(114.884,min(255.322,94.5),min(255.8 82,94.5,193.12)=94.5, that is, the default protection section is Overlap2 or Overlap3.

[0073] Among them, S XY The X and Y in the above example correspond to the AG point, S PQ P and Q in the above example correspond to the AG point, V PQ The PQ in the figure corresponds to the turnout numbers 1-5 in the above example.

[0074] Of course, in addition to the specific forms described above, the emergency brake trigger speed calculation formula may also be in other forms, which are not limited in the embodiments of the present invention.

[0075] As a preferred embodiment, the minimum emergency brake trigger speed is used as the target emergency brake trigger speed, and the protection zone to which the target emergency brake trigger speed belongs is used as the target protection zone for the train to enter, so that the speed of the train is controlled according to the target emergency brake trigger speed. The method includes:

[0076] The end point of the protection section to which the target emergency brake trigger speed belongs is used as the authorized end point of the train's movement on the target route, so that the train speed can be controlled according to the target emergency brake trigger speed.

[0077] Specifically, considering that in traditional applications, the currently open protection section among the protection sections included in the target route is usually determined by setting up multiple American dynamic beacons, and then the end point of the currently open protection section is used as the authorized movement end point of the train in the target route. In this way, the relevant speed control system can control the speed of the train according to the emergency braking trigger speed of the currently open protection section. Therefore, in order to reduce the changes to the original control logic, after determining the target emergency braking trigger speed, the embodiment of the present invention can use the end point of the protection section to which the target emergency braking trigger speed belongs as the authorized movement end point of the train in the target route, so as to control the speed of the train according to the target emergency braking trigger speed.

[0078] As a preferred embodiment, the controller is ATP.

[0079] Specifically, ATP has the advantages of high stability and strong performance.

[0080] Of course, in addition to this specific type, the controller can also be of many other types, which is not limited in the embodiment of the present invention.

[0081] As a preferred embodiment, the minimum emergency brake trigger speed is used as the target emergency brake trigger speed, and the protection zone to which the target emergency brake trigger speed belongs is used as the target protection zone for the train to enter, so that the speed of the train is controlled according to the target emergency brake trigger speed. The method includes:

[0082] Push the emergency braking trigger speed and minimum emergency braking trigger speed of each protection zone for the train included in the target route to the human-computer interaction interface;

[0083] In response to a confirmation instruction received through the human-computer interaction interface, the minimum emergency braking trigger speed is used as the target emergency braking trigger speed, and the protection zone to which the target emergency braking trigger speed belongs is used as the target protection zone for the train to enter;

[0084] In response to the received modification instruction, the designated speed is used as the target emergency brake triggering speed.

[0085] Specifically, considering that due to calculation errors and other reasons, the target emergency braking trigger speed determined by the controller may not be the minimum of the emergency braking trigger speeds of the train in the various protection sections included in the target route. Therefore, in order to further improve the safety of train operation, the embodiment of the present invention adds a manual confirmation link before controlling the speed of the train according to the target emergency braking trigger speed. That is, the emergency braking trigger speeds of the train in the various protection sections included in the target route and the minimum emergency braking trigger speed can be pushed to the human-computer interaction interface so that the staff can confirm the information. If the confirmation is correct, a confirmation instruction can be sent. If there is a problem, a modification instruction can be sent so that the controller will use the specified speed as the target emergency braking trigger speed.

[0086] Among them, the method of giving the specified speed can be in many specific forms, for example, it can be a specified speed issued by the staff together with the modification instruction through the human-computer interaction interface, or it can be a specified speed pre-stored in the controller, etc. The specified speed is usually a smaller value to ensure the safety of train operation.

[0087] As a preferred embodiment, when entering a target route, obtaining the emergency braking trigger speed of each protection section included in the target route for the train includes:

[0088] When entering the target route, determine whether there is a target emergency braking trigger speed for each protection zone included in the target route;

[0089] If it does not exist, executing the step of obtaining the emergency braking triggering speed of each protection section included in the target route for the train;

[0090] If so, determine whether the protection section update instruction of the target route is received;

[0091] If received, the step of obtaining the emergency braking trigger speed of the train for each protection section included in the target route is executed.

[0092] Specifically, considering that the train may repeatedly pass through the target route of the station during continuous operation, that is, the target emergency braking trigger speed of the target route may have been calculated before when passing through the target route, and considering that the protection section of the target route may also be updated, the embodiment of the present invention can determine whether the target emergency braking trigger speed of each protection section included in the target route exists when entering the target route of the station. If not, the step of obtaining the emergency braking trigger speed of each protection section included in the target route for the train can be executed. If so, it can be determined whether the protection section update instruction of the target route is received. If not, it means that the protection section of the target route has not been updated. The train speed can be controlled according to the current target emergency braking trigger speed of the target route. If received, it means that the protection section of the target route has been updated. Therefore, the step of obtaining the emergency braking trigger speed of each protection section included in the target route for the train can be executed to determine the target emergency braking trigger speed of the target route after the protection section is updated.
