The railway communication system, as the central nervous system, is an important infrastructure for railway transportation command and operation management, playing a crucial role in ensuring railway transportation safety. Recently, in order to enhance the safety and stability of the operation of the Qinghai Tibet Railway, the Xining Communication Section of the Qinghai Tibet Railway has comprehensively upgraded its video conferencing and transportation command system using the Kodi Kd-MF-16 high-definition multi format hybrid matrix. It has now been officially put into use.

The Kd-MF series high-definition multi format hybrid matrix is a high-performance modular plug-in matrix system that can reach a scale of 288 x 288 and can flexibly configure input and output boards for multiple signals and formats. Based on the characteristics of no compression, no loss, and no distortion in the transmission signal image, as well as high-definition, real-time, and no delay in the signal transmission process, we achieve true "full HD" signals and output high-quality, jitter free signal images. Because separate matrices are no longer needed to process signals and various converters are no longer needed to achieve signal conversion, the stability and reliability of the system are greatly improved while simplifying the system and reducing costs.

Since its establishment, the Xining Communication Section has taken on the important task of communication management for the Qinghai Tibet Railway. From bidding to construction and acceptance, Dalian Kedi has demonstrated a high level of professional spirit and cooperative attitude, and has been striving for excellence in equipment quality. It also strives to maintain the concept of "matrix expert" technology with "zero defects", "zero equipment failures", and "zero service errors".
