摘　　要：随着实时以太网技术的飞速发展,中国铁路速度的不断提高,铁路时间同步网需要为其各个系统提供准确的时间信息,才能保障列车的行车安全,因此对于时间的统一非常重要。以铁路同步网为背景,通过介绍IEEE1588协议中的IEEE 802.1 AS协议,对列车的各个系统之间如何进行精确时间同步进行研究。提出了时钟同步模型和延时测量机制,对主从时钟之间的通信进行分析,以减小系统之间的误差,提高可靠性。With the rapid development of real-time Ethernet technology and the continuous improvement of China’s railway speed,the railway time synchronization network needs to provide accurate time information for its various systems to ensure the safety of trains.Therefore,the unification of time is very important.Based on the railway synchronization network,this paper introduces the IEEE 802.1 AS protocol in the IEEE1588 protocol to study how to perform precise time synchronization between the various train systems.A clock synchronization model and a delay measurement mechanism are proposed to analyze the communication between the master and slave clocks to reduce errors between systems and improve reliability.
