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。

摘要：The Ethernet and field-bus communications are used in the machine control system （MCS） of HL-2A. The control net, with a programmable logic controller （PLC） as its logic control master, an engineering control management station as its net server, and a timing control PC connected to a number of terminals, flexibly and freely transfers information among the nodes on it with the Ethernet transmission techniques. The PLC masters the field bus, which carries small pieces of information between PLC and the field sites reliably and quickly. The control net is connected into the data net, where Internet access and sharing of more experimental data are enabled. The communication in the MCS guarantees the digitalization, automation and centralization. Also provided are a satisfactory degree of safety, reliability, stability, expandability and flexibility for maintenance.
