摘要
CTCS-3级列控业务作为铁路专用无线通信中最关键的业务,迫切需要开展在铁路下一代移动通信系统(LTE-R)下的适应性研究。本文依托于中国国家铁路集团的课题"基于LTE-R的CTCS-3级列控系统关键技术研究及应用",提出了提高数据传输可靠性的车地无线通信方案,即在CTCS-3级列控系统中采用双通信单元冗余传输来代替现有的双通信单元无冗余传输工作模式。
As the most critical service in railway-specific radio communication,it is urgent to conduct adaptive research on the CTCS-3 level train control service over next-generation mobile communication for railway.With the support of the project"Research and application of key technology of CTCS-3 level train control system based on LTE-R"from China State Railway Group Co.Ltd.,a wireless channel connection scheme for improving the reliability of data transmission is proposed,in which a dual-station redundant working mode is adopted to replace the existing working mode of dual-station non-redundant transmission.
