Abstract

The invention provides vehicle-mounted access equipment, a control method thereof and a rail vehicle. The vehicle-mounted access equipment comprises a first communication module and a second communication module which are redundant to each other and are respectively used for data transmission with ground equipment; the logic processing assembly is used for determining the current data processing logic according to the current communication mode of the vehicle-mounted access equipment, processing at least one path of communication data sent by the first communication module and the second communication module according to the data processing logic so as to generate communication data to be forwarded, and sending to-be-forwarded communication data to the main control assembly, wherein the atleast one path of communication data comprises at least one of business data and train automatic control system data. According to the invention, transmission of the service data and the train automatic control system data can be realized, the resource utilization rate of the vehicle-mounted access equipment is improved, and the technical problem of low TAU resource utilization rate in the priorart is solved.

Description

technical field [0001] The present application relates to the technical field of vehicle communication, and in particular to a vehicle access device, a control method thereof, and a rail vehicle. Background technique [0002] With the rapid development of communication technology, especially radio technology, people began to study the train operation control system based on communication technology. Communication Based Train Control System (CBTC) is such a system, which uses communication The medium replaces the track circuit as the medium, realizing the two-way communication between the train and the ground equipment. [0003] The CBTC system carries the communication between the train and the ground. The data transmitted by the CBTC system occupies an important position in the train control. Once the data is lost, it will cause adverse consequences to the train operation. In order to ensure the reliability of the CBTC data, in related technologies, two train access units ...
