摘要
上海同步辐射装置储存环的高频低电平反馈控制采用数字技术来实现,反馈环路的参数设置和状态都从网络通讯接口写入和读出,同时,对构成数字化低电平系统重要组成部分的本振信号和时钟信号的配置也通过网络通讯来实现。该通讯接口的设计首先是以NIOS II处理器为核心构建嵌入式系统,然后在其上运行MicroC/OS-II实时操作系统,最后采用轻量级的TCP/IP(LwIP)来实现其通讯功能。通过长期的测试与运行,该通讯网络能够稳定运行。
Low Level RF（LLRF） control system for storage ring of Shanghai Synchrotron Radiation Facility（SSRF） has been built by digital technology. The settings of parameters and the feedback loop status are carried out through the network communication interface, and the local oscillation and clock, which is the important component of the digital LLRF control system, are also configured through network communication. NIOS II processor was employed as a core to build the embedded system with a real-time operating system MicroC/OS-II, finally Lightweight TCP/IP（LwlP） was used to achieve the communica tion interface. The communication network is stable after a long-term operation.
