The 4400 HP AC traction freight diesel locomotive is a new-generation diesel locomotive product developed by CRRC Dalian Co., Ltd. based on the mature "Harmony" series of diesel locomotives and is a new member of the "Fuxing" locomotive family. CRRC Dalian R&D has equipped this model with a network control system.
Main Technical Highlights:
i. A ring topology structure and the TRDP (Time-Triggered Real-time Data Protocol) are employed to achieve reliable real-time Ethernet communication.
ii. Single Ethernet communication is used, which significantly increases the speed of data interaction and the forwarding speed of large data sets for multiple-unit operations.
Iii. The vehicle Ethernet is a switched Ethernet, with a ring topology enabling point-to-point connections between terminal devices and switches. The bus status is less affected by individual devices.
