Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
The scheme is realized by utilizing a train automatic monitoring system (ATS) to track the position of the train and matching the train automatic monitoring system (ATS) with a train automatic control system (ATC).
A rear vehicle forbidden parking area is defined in the system, the front pantograph and the rear pantograph of the train are prevented from falling in the pantograph forbidden parking area, the area is designed and obtained based on the mileage of an inlet point A and an outlet point B of the pantograph forbidden parking area and the distance between the pantograph of the train and the vehicle end, the front vehicle forbidden parking area is designed according to the control relation between an automatic train driving system (ATO) and an automatic train protection system (ATP), and the rear vehicle is prevented from being tightly tracked to stop in the rear vehicle forbidden parking area when the current vehicle is located in the front vehicle monitored area.
By means of the condition of mastering global information by an ATS train monitoring system, a specific interface is newly added between the ATS system and a vehicle-mounted system, the train is interfered in advance, the ATS monitoring train is positioned in detail, when the train enters at an entrance E point of a front train monitoring area and is in a parking state, a specific interface code bit is triggered to the train, when the train receives the specific code bit sent by the ATS, the vehicle-mounted ATO controls the train to park at an entrance C point of a rear train forbidden parking area.
The current car continues to travel, the car head passes through the outlet F point of the monitoring area of the front car, the ATS cancels the specific code bit to the car, and the rear car automatically resumes the ATO operation and continues to launch.
As shown in fig. 2, consider that in a limit situation, the rear vehicle may be attached to the front vehicle tail, ensuring that the rear front pantograph falls outside the entry point a of the pantograph stop-keeping area. According to the point mileage KP1 of the entrance A of the forbidden region of the pantograph and the length D1 of the front pantograph from the vehicle end, the point mileage KP3=KP1+D1 of the entrance C of the forbidden region of the rear vehicle is calculated, and then the point mileage KP5=KP3+D2 of the entrance E of the monitoring region of the front vehicle is calculated by KP3 and the length D2 of the train.
The minimum headstock of the current train enters the E point and stops running, the ATS sets a forbidden state of the rear forbidden parking area to the ATC, and the ATC controls the train to stop at the C point of the entrance of the rear forbidden parking area to forbidden the train to enter the rear forbidden parking area.
As shown in fig. 3, considering that in the limit situation, the maximum positioning error of the front vehicle tail generating system ensures that the rear pantograph of the rear vehicle falls outside the exit point B of the pantograph forbidden region. According to a pantograph forbidden parking area outlet point B mileage KP2 and a length D3 of a front pantograph from a vehicle end, calculating a rear forbidden parking area outlet point D mileage KP4=KP2+D3, and calculating a front vehicle monitoring area outlet point F mileage KP6=KP4+D4+D5 by KP4, a system maximum error parameter D4 and a train length D5, wherein D4 consists of an EOA safety margin, an ATO approach ATP distance and a front vehicle tail maximum positioning error.
The minimum locomotive of the current car passes through the outlet F point of the front car monitoring area, the ATS sets the permission state of the rear car forbidden parking area to the ATC, and the ATC controls the normal running of the train to avoid the occurrence of parking in the rear car forbidden parking area.
The configuration of data for the front car supervision zone and the rear car park zone is performed in the system as shown in fig. 4, and the ATS system continuously tracks the minimum head position of the train and monitors the front car supervision zone.
Under normal conditions, no train exists in the current train supervision area or the train is not parked in the area, the ATS sets the rear train forbidden parking area to be in an allowed state and informs the ATC, and the ATC controls the train to normally run.
If the train is monitored to enter the front train monitoring area and stop, the ATS sets the rear train stopping area to be in a forbidden state and informs the ATC, and at the moment, the ATC controls the train to stop outside the entrance of the rear train stopping area. The current car resumes operation or the minimum locomotive leaves the exit of the monitoring area of the front car, the forbidden parking area of the ATS is in an allowed state after the ATS is recovered, and the ATC controls the normal operation of the train.
Considering that after the ATS prohibits the rear parking area, the rear parking area cannot be restored to the allowed state due to communication failure or train dislocation, under the scene, the CC-ATS communication interruption exceeds 60s (the fact that the front vehicle is driven away from the front vehicle monitoring area under the normal state can be ensured) or the CC is self-dislocated, the CC automatically restores the allowed state of the rear parking area, when the communication restoration or the train positioning restoration is carried out, the ATS judges that the train position still meets the forbidden condition of the rear parking area, and then the forbidden state is generated for the CC again.
