Description
Technical Field
The present invention relates to a train signal control system, and in particular, to a method, apparatus, and medium for calculating a mobile authorization.
Background
In a mobile occlusion based train control system, the vehicle device calculates the parking spot through a movement authorization provided by the RBC (Radio Block Center, wireless occlusion center). The existing system has relatively single mobile authorization transmitting source, and if the mobile authorization provided by RBC is wrong, train-mounted equipment cannot be distinguished, so that accidents can be possibly caused. The vehicle-to-vehicle communication is researched and applied on subways, and the vehicle-mounted autonomous calculation of the driving license is performed based on the working condition information such as the speed, the position and the like of the front vehicle obtained by the vehicle after the vehicle-to-vehicle communication. And the vehicle-mounted equipment performs curve calculation and comparison on the autonomously calculated mobile authorization and the mobile authorization sent by the ground equipment, and monitors train operation according to the strictest conditions.
The precondition of vehicle-mounted autonomous calculation of driving permission is to establish communication with a preceding vehicle. There are many ways how to obtain the communication address of the front car, because the RBC grasps the location information of all communication trains in the jurisdiction, and the simplest way is to obtain the communication address through the RBC. If the front car communication address is acquired through the RBC, the mobile authorization calculation error caused by the RBC fault cannot be prevented. Many specialists therefore propose to calculate and provide the communication address of the preceding vehicle by a TSRS (temporary speed limiting server). However, when the TRSR is studied to calculate the communication address of the preceding vehicle, it is found that if the preceding vehicle is a non-communication vehicle having no communication or a failure vehicle having a communication failure (hereinafter, collectively referred to as a non-communication vehicle), the following vehicle can only transmit a driving license to drive according to RBC because communication with the preceding vehicle cannot be established, or a danger caused by RBC errors cannot be avoided.
The retrieved China patent publication No. CN115257864A discloses a train-to-train communication train control system and method, and specifically discloses that the system comprises: the system comprises a TSRS, vehicle-mounted equipment and RBC, wherein the TSRS is used for sending an electronic map to a train; the vehicle-mounted equipment is used for determining train position information according to the electronic map and satellite navigation data; the RBC is used for obtaining front and rear train information of the train according to the train position information and other train position information, so that the train can establish train communication with the front train according to the front and rear train information, and the effective position information of the front train can be obtained through the train communication.
However, the existing patent mainly aims at guaranteeing the driving safety of a train and shortening the running interval of the train to the greatest extent, and the TSRS does not send mobile authorization information, so that the danger caused by calculation errors of the RBC system is reduced, the safety of the system is improved, and the technical problem to be solved is solved.

The TSRS calculates the mobile authorization according to the occupation condition of the front section and sends the mobile authorization to the rear vehicle, and the related processing is as follows:
A. if the TSRS calculates that the front occupation is the non-communication vehicle occupation, the TSRS takes the starting end of the occupation section as the driving permission terminal point of the rear vehicle.
B. If the TSRS calculates that the front occupation is the communication vehicle occupation, the TSRS calculates a movement authorization terminal point according to the position of the tail part of the front vehicle and considering a certain safety distance, and sends corresponding movement authorization to the rear vehicle.
