Data for: Research Progress of HL-2M Distributed Timing System

Referring to the design scheme of ITER (International Thermonuclear Experimental Reactor) Time Communication Network （TCN）, combined with the actual situation of HL-2M, the distributed timing system based on IEEE 1588-2008 (Precision Time Protocol) has been studied, which can realize multiple triggering functions including single pulse, uniform pulse train, non-uniform pulse train and other arbitrary pulse types to meet the actual needs and improves the clock synchronization and triggering accuracy of HL-2M timing system from microsecond level to sub-microsecond level, and ultimately better than 100 nanoseconds.参照国际热核聚变实验堆（International Thermonuclear Experimental Reactor，简称ITER）时间通信网络（Time Communication Network，简称TCN）的设计方案，结合HL-2M装置的实际工况，本研究针对基于IEEE 1588-2008（精确时间协议，Precision Time Protocol）的分布式定时系统展开研究。该系统可实现单脉冲、均匀脉冲串、非均匀脉冲串等多种任意脉冲类型的触发功能，以满足实际应用需求；同时将HL-2M定时系统的时钟同步与触发精度从微秒级提升至亚微秒级，最终精度优于100纳秒。
