Abstract

Abstract: According to the requirement of timing accuracy of HL-2M tokamak and referring to the design scheme of ITER, the HL-2M timing synchronization network based on precise time protocol is designed, the accuracy of clock synchronization and event triggering of HL-2M tokamak is improved from microsecond level to sub-microsecond level, and is ultimately better than 100 nanoseconds.

Key words: HL-2M tokamak, Timing synchronization network, Precision time protocol

摘要： 基于 HL-2M 装置对时序精度的要求，参考 ITER 的设计方案，设计了基于精确时间协议(PTP)的 HL-2M 分布式时间通讯网络，使 HL-2M 装置的时钟同步和事件触发的精度从微秒级提高到亚微秒级，最终优于 100ns。
