摘　　要：郑许市域铁路是国内无人驾驶市域铁路示范工程,设计时速超过120 km。因此,在运行中就对通信系统提出了更高的实时性、可靠性和安全性的要求。特别是对于长度为28.73 km的高架段长大区间,需要更为可靠的通信技术及冗余方案。本文依托郑许市域铁路工程应用,面向行车安全的长大区间通信光缆高可靠性冗余布设问题,提出了BBU+RRU组网交叉冗余布缆优化方案。该方案有效利用了BBU和RRU组网覆盖距离广、带宽高、抗干扰能力强、安全可靠等优势,设计了RRU布设方案并对其工程实现进行了讨论,该研究对长大区间通信光缆冗余设计和施工起到参考作用。Zhengzhou-Xuchang Municipal Railway is a demonstration project of driverless municipal railway in China,with a designed speed of more than 120 km/h.Therefore,higher real-time,reliability and security requirements are put forward for the communication system during the operation.Especially for the 28.73 km long elevated section,more reliable communication technology and redundancy scheme are needed.Based on the application of railway engineering in Zhengzhou-Xuchang,this paper proposes an optimization scheme of cross redundant cable laying in BBU+RRU network for high reliability redundancy laying of long section communication optical cable for traffic safety.This scheme makes effective use of the advantages of BBU and RRU network,such as wide coverage distance,high bandwidth,strong anti-interference ability,safety and reliability.The RRU layout scheme is designed and its engineering implementation is discussed.The research can be used as a reference for redundant design and construction of communication cable in long section.
