Title:
COMMUNICATION METHOD, APPARATUS, AND SYSTEM, AND TRAIN
Document Type and Number:
WIPO Patent Application WO/2024/098994
Kind Code:
A1
Abstract:
A communication method, which relates to the field of optical fiber communications, and is applied to a processor (22) in any carriage of a train. The processor (22) is connected to an optical fiber ring network, and the processor (22) performs communication data interaction with a train communication device in a carriage, and then performs communication data interaction in an optical signal form with the optical fiber ring network, so as to implement communication between the train communication devices in different carriages. Data transmission is performed by an optical fiber instead of a cable, so that communication data is not prone to loss and is not susceptible to electromagnetic interference, thereby improving the communication quality of the train communication devices; moreover, the communication data of the plurality of train communication devices is converted into optical signals and combined into a beam of light for transmission, so that only one optical fiber ring network is required for simultaneous data transmission of the plurality of train communication devices, without establishing a plurality of communication networks, thereby reducing the complexity of a wiring environment in the train, and reducing the total weight of the train. Also provided are a communication apparatus and system, and a train.
