Description
Technical Field
The invention relates to the technical field of rail transit, in particular to a train screening method and system based on mobile blocking.
Background
The screening (called as 'front screen' for short) at the front end of the train is a precondition that a radio block center RBC on the ground calculates the train permission to be upgraded, and the RBC confirms whether a hidden train exists in front of the train to be upgraded or not through the screening at the front end of the train so as to ensure the running safety of the train. When the screening of the front end of the train to be upgraded is successful, the RBC starts to try to calculate the driving permission for the train. Therefore, the completion of the front-end screening of the train is particularly important, and is a precondition that the train can be normally upgraded to be a mobile block-level train.
The process of the existing screening method for the front end of the train is as follows:
1) the RBC checks that the distance between the reported train head position and the front axle counter is not more than the shortest possible length of the train on the line according to the position information reported back by the train;
2) and checking whether the front end screening area in the train running direction is idle according to the occupation/idle information of the axle counting section input by the computer interlocking CI, and if the front end screening area is idle, successfully screening the front end.
As shown in figure 1, the distance S between the train head and the front axle counter is smaller than the shortest possible length L on the lineminAnd at least one front axle counting section (between axle counting A and B) is idle, the RBC judges that the screening of the front end of the train is successful.
However, as shown in fig. 2, the shortest vehicle length in the heavy-duty train line is the locomotive length, which is about 33 meters. When the screening process of the front end of the train is adopted, the distance between the train head and the front axle counter is too close. In consideration of communication delay, the condition that the train passes over a front axle counter but is not upgraded occurs, so that the RBC cannot calculate the driving permission for the train.
In addition, as shown in fig. 3, when the distance from the head position of the train to the first front teleseme is a visual distance, and a driver can visually confirm that no train occupies the area, since the distance between the head position of the train and the front axle counter is still greater than the shortest possible length on the route, although no train exists in the front, the train can not calculate the driving permission for the train according to the front screening process, and the train still needs to be driven according to the visual driving mode, which seriously affects the upgrading efficiency of the heavy-load train.

wherein the manual front screen condition comprises:
the axle counting section where the vehicle head is located is a first axle counting section outside a first front frame signal machine;
the occupancy of the next meter shaft zone ahead is idle.
In order to carry out manual front screen operation by a driver, the distance of the front screen needs to be ensured to be a visual visible distance, and a clear reference object, namely an annunciator exists, so that the manual front screen confirmation range is selected to be the first axle counting section outside the first front annunciator. Because the semaphore is very close to the axle counter and is inside the axle counter, there is no safety risk in selecting the semaphore as a reference.
The 'interior side' and the 'exterior side' are terms in the field of rail transit, and the distinction is based on the direction of protection, the aspect of signal machine protection is the interior side, and vice versa. In step S43, by comparing the axle counting section where the vehicle head is located with the pre-stored position of the annunciator, it can be determined whether the axle counting section where the vehicle head is located is the first axle counting section outside the first front annunciator, that is, there is no other axle counting section between the axle counting section where the vehicle head is located and the first front annunciator.
