For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flow chart of a method for confirming a protection section of a train route according to the present invention, where the method for confirming the protection section of the train route is applied to a controller on a train, and includes:
s101: when entering a target route, acquiring the emergency braking triggering speed of each protection section contained in the target route for the train;
specifically, in view of the technical problems in the background art, in combination with consideration that different emergency braking trigger speeds are set for the train in each protection section included in the target route, the emergency braking trigger speeds are set for preventing accidents of the train, namely, a speed threshold capable of triggering the train to generate emergency braking is set for ensuring that the speed of the safety train is prevented from exceeding the emergency braking trigger speeds as much as possible, if the train can perform speed control on the minimum one of the emergency braking trigger speeds of the train according to each protection section included in the target route when the train is driven along the target route, no matter which protection section the train is driven into, therefore, based on the concept, the speed control is performed on the train according to the minimum emergency braking trigger speed of each protection section included in the target route when the train is driven along the target route in the embodiment of the invention, and therefore, in the step, the emergency braking trigger speeds of the train according to each protection section included in the target route can be obtained when the train is driven into the target route first.
The present invention may be applied to a variety of different control systems, and embodiments of the present invention are not limited herein.
Specifically, the emergency braking triggering speed may be obtained in multiple manners, for example, the emergency braking triggering speed of each protection section of each approach may be obtained by inquiring in a manner of pre-storing the emergency braking triggering speed, or may be obtained by calculating related parameters, or may be obtained by inputting by a worker, or the like.
S102: and taking the minimum emergency braking trigger speed as a target emergency braking trigger speed, and taking a protection zone to which the target emergency braking trigger speed belongs as a target protection zone to which the train is to be driven, so that the speed of the train is controlled according to the target emergency braking trigger speed.
Specifically, after the emergency braking trigger speed of each protection section of the target route is obtained, based on the above thought, the minimum emergency braking trigger speed can be used as the target emergency braking trigger speed, so that the minimum emergency braking trigger speed can be used as the data base of the subsequent steps.
Specifically, after the target emergency braking trigger speed is selected, the speed of the train can be controlled according to the target emergency braking trigger speed, so as to control the train to run in a speed interval below the target emergency braking trigger speed, and prevent the emergency braking from being triggered in the running process of the protection zone, thereby generating a safety accident.
Specifically, the beacon is a basic device for realizing train positioning by CBTC (Communication Based Train Control System, communication-based train operation control system), and the dynamic beacon is a key device for supporting the point-type level operation of the train. Compared with European beacons, the American beacons have lower cost, and are particularly an ideal choice which is quite economical for some trams or urban railways with low requirements on train tracking intervals, running point levels and small transmission information quantity. The American dynamic beacons are connected with the annunciators through hard wire circuits, and the corresponding American dynamic beacons are activated when the annunciators are driven to be in an allowed state by the interlocking system. When the signal machine corresponding to the initial end of the route has a plurality of routes, american dynamic beacons are required to be added at the same position, and when the same route has a plurality of protection sections, american dynamic beacons are required to be added at the same position, and a large number of American dynamic beacons are required to be arranged at higher cost.
The invention provides a method for confirming a protection zone of a train route, which considers that if a train carries out speed control according to the minimum emergency braking trigger speed in each protection zone of the target route, no matter which protection zone the target route is open, the running safety can be ensured, so that when the train enters the target route, the emergency braking trigger speed of each protection zone contained in the target route for the train can be obtained, the minimum emergency braking trigger speed is taken as the target emergency braking trigger speed, and the protection zone to which the target emergency braking trigger speed belongs is taken as the target protection zone to be driven in, therefore, the train theoretically does not need to know the information of the current only open protection zone of the target route, and the arrangement cost of dynamic beacons can be reduced, thereby reducing the cost of trackside equipment.
Based on the above embodiments:
as a preferred embodiment, acquiring the emergency braking triggering speed of each protection segment included in the target route for the train includes:

and determining the emergency braking triggering speed of each protection section of the target route for the train based on the braking acceleration of the train, the turnout speed limit information of each protection section and the section track length information.
Specifically, considering that the emergency braking triggering speed of the protection section for the train is related to the braking acceleration of the train, the speed limit information of the turnout in the protection section and the length information of each section track, the method and the device can firstly acquire the turnout speed limit information of each protection section contained in the target route and the section track length information divided on the basis of the turnout, and then determine the emergency braking triggering speed of each protection section of the target route for the train on the basis of the braking acceleration of the train, the turnout speed limit information of each protection section and the section track length information, and can improve the accuracy of the acquired emergency braking triggering speed of each protection section for the train in a real-time calculation mode.
