Abstract: Based on FPGA and ieee1588PTPv2 protocol, HL-2M timing control system is designed to 
provide trigger for the measurement and control system at precise time. The client/server dual-mode management 
is applied in the data acquisition system. In HL-2M first plasma discharge experiment, the test results showed that 
the time sequence control and acquisition system had the characteristics of nanosecond precision level trigger, 
strong real-time performance, fast data transmission speed, stable and reliable, convenient deployment and 
management. The timing control and data acquisition systems meet the application requirements of HL-2M first 
plasma discharge experiment.

摘要： 基于 FPGA 和 IEEE1588PTPv2 协议设计了 HL-2M 装置时序控制系统，用于在精准时刻为测控系统
提供触发。数据采集系统采用客户端/服务端双模式管理。在 HL-2M 装置初始等离子体放电实验中测试结果表明，
时序控制和采集系统具有纳秒级精度触发，实时性强，数据传输速度快，稳定可靠，方便部署和管理的特点，满
足 HL-2M 等离子体放电实验的应用需求。
