Motor train unit cross-platform communication system and motor train unit cross-platform passenger information communication system and method

Abstract

The invention provides a motor train unit cross-platform communication system, and further provides a motor train unit cross-platform passenger information communication system and method on the basisof the motor train unit cross-platform communication system. The motor train unit cross-platform communication system comprises a first motor train unit platform and a second motor train unit platform which adopt different communication buses; reconnection gateways are arranged in a head train and / or a tail train of the first motor train unit platform and / or the second motor train unit platform and communicate with system controllers of the two motor train unit platforms, and a protocol conversion unit is arranged in the system controller of the motor train unit platform with the reconnectiongateways and used for data conversion between the different communication buses. According to the communication method of the motor train unit cross-platform passenger information system, data transit between two trains is achieved through the reconnection gateways, and conversion of two different data formats is achieved through the protocol converter. The system and method can be applied to interconnection of different technical platforms, flexible combination between motor train units is achieved, and the utilization rate of the motor train units is increased.

Description

technical field [0001] The invention relates to the technical field of communication, an EMU cross-platform communication system, a cross-platform passenger information communication system and a method. Background technique [0002] As one of the full-train networking systems of the EMU, the passenger information system has functions such as display inside and outside the train, automatic station announcement, broadcast intercom and entertainment. From the perspective of system architecture, the passenger information system of an EMU includes a system controller, 8 car controllers and terminal equipment in each car (display screens, telephones, etc. inside and outside the car), among which, the system controller and car The controllers are called the first-level network, and the car controllers and peripheral devices are called the second-level network. System architecture such as figure 1 shown. [0003] Currently, the existing short train sets in China generally use 8 ...
