The Wireless Transmission Device (WTD) is a device that collects onboard intelligent monitoring data
and train network transmission data and transmits it to the ground data center via 4G/5G/WIFI. The wireless
transmission system realizes the centralized management of listed data, the comprehensive display of listed
faults and status data on the ground. It is used for vehicle status analysis and full life cycle health management.
