The wireless transmission system (WTS) is a centralized platform for the collection of vehicle information. It collects and
summarizes the information on the train to achieve unified information transmission and is responsible for the communication
management and data recording of train information. It mainly completes the collection of train status information, safety
information and other information, and performs analysis, processing and recording to achieve big data storage of train
information. Through two-way data interaction between the train and the ground, data file compression processing, data file
download, etc., it provides data support for train operation, inspection and maintenance, and provides actual data support for
train design reference.
