In step 110, a train travel path may be determined based on different train types.
Wherein, the train type can be a planned train or an unplanned train. The train travel path may include the currently triggered route or the next route.
In the embodiment of the invention, the current route is a route for a train to go to a target turnout, and the target turnout can be a planned or unplanned section. The next route is the route for the train to reach the next platform.
And searching for a protection section based on the current route and the next route of the train, and judging whether the current route is configured with a mandatory protection section. The mandatory protection zone may be a preset fixed protection zone.
In step 120, when it is determined that the current route does not have the mandatory protection segment, the protection segment list corresponding to the current route is traversed.
The protection zone list may include information related to all protection zones in the current route, and the related information may include the length of the protection zone, the target switch direction, and the corresponding route type.
It can be understood that the target turnout direction can be determined according to the current route and the next route, so that the target protection section can be conveniently and quickly screened out, and meanwhile, the screening efficiency and accuracy of the protection section can be improved.
In some embodiments, in the event that it is determined that a mandatory protection section exists for the current route, the mandatory protection section is determined to be the target protection section.
In actual implementation, if the current route is configured with a mandatory protection section, the mandatory protection section can be preferentially used as a target protection section, so that a customizable protection section screening mechanism can be realized, train operation efficiency and driving safety can be improved based on the mechanism, and adaptability of section screening is improved.
The protection zone selection method provided by the invention can add a protection zone screening mechanism according to the mandatory protection zone so as to meet special scenes.
In step 130, the first section corresponding to the next route or the protection section consistent with the target turnout direction is screened out from the protection section list, that is, the protection section meeting the preset condition in the protection section list is determined as the target protection section.
The protection zone selection method provided by the invention determines the train operation route according to the train type, screens the protection zone according to the corresponding relation between the route and the protection zone, and can accurately, efficiently and quickly determine the target protection zone.

determining a current route and a next platform based on an operation plan of a planning vehicle;
determining all routes triggered by a tail end annunciator of the current route based on the current route;
the next route is determined based on all routes and the next station triggered by the end semaphores.
In actual implementation, taking a planned train as an example, where the planned train is a train with a running plan, the train running path may be determined according to the running plan of the train.
When the train driving to the target turnout is a planned train, the train triggers a route going to the turnout, and the route is the current route. The tail end of the approach path is the starting end of the target turnout, and the protection section of the target turnout needs to be judged according to the planned path.

In actual implementation, the screening scheme of the head yard vehicle protection section is similar to that of a planned vehicle, and the head yard vehicle is an unscheduled vehicle with a destination and capable of realizing automatic triggering of a route.
The difference between the head yard vehicle and the planned vehicle is that when the next route is obtained, the tail end signal machine of the current route is used as the starting end signal of the next route, all routes or route tables which can be triggered by the tail end signal machine of the current route are obtained, and then routes which can reach the destination of the head yard vehicle are screened from all routes or route tables, namely the next route is obtained.
The screening mode of the subsequent protection section is the same as that of the planned vehicle, and is not described herein again.
The method for selecting the protection sections can be used for screening reasonable protection sections by combining the planned train and the head-mounted train traveling direction or the traveling path.
In some embodiments, after determining the mandatory protection zone as the target protection zone, the method further includes:
and in the case that the mandatory protection section cannot meet the protection section triggering condition, reselecting the target protection section based on the protection section priority.
In actual implementation, the protection zone priority list may be increased only if the mandatory protection zones are not sufficient to satisfy the protection zone trigger condition.
And under the scene that the target protection zone cannot be issued, preferentially selecting the protection zone with the highest priority based on the protection zone priority list.
The protection zone priority is used to indicate the preset level of different protection zones. The preset level may be "high, medium, and low". The preset level "high" is the highest priority, the preset level "medium" is the second priority, and the preset level "low" is the lowest priority. It is to be understood that the above preset levels are only used as examples, and the priority setting may be determined according to the requirement, and is not particularly limited herein.
In some embodiments, after determining the mandatory protection zone as the target protection zone, the method further includes:
and under the condition that the target protection section cannot be issued, reselecting the target protection section based on the priority of the protection section.
The priority screening mechanism may be triggered in a special scenario, which may be some scenarios that cannot be reasonably screened to the protection zone and delivered.
In the following abnormal case, the target protection zone cannot be normally issued. For example: under special signal conditions, extreme weather, train equipment faults, abnormal running organization or abnormal line application and other special scenes, a reasonable protection section cannot be issued.
At this time, the protection zone with the highest priority may be preferentially selected based on the protection zone priority list.
The protection zone selection method provided by the invention can add a special screening mechanism according to a special scene, namely, can add a protection zone screening mechanism according to the priority list so as to meet the special scene. Based on the mechanism, the train operation efficiency and the driving safety can be improved, and the adaptability of section screening is increased.
