中国科学院近代物理研究所自主研发的ADS 162.5 MHz高频低电平控制采用数字化技术实现，控制环路的参数设置、开闭环操作以及状态监测都通过监控系统实现。该系统基于以太网通讯，采用轻量化客户端-服务器端的工作方式，运行在上位机的客户端程序发送指令数据包，运行在高频数字低电平系统的服务器端响应指令，完成参数监测与控制。系统首先以Atera公司Stratix III系列现场可编程门阵列(FPGA)开发板为基础，构建以Nios II处理器和三速以太网接口为核心的服务器端硬件系统；其次基于Micro C/OS II实时操作系统和轻量级TCP/IP协议栈，设计服务器端软件系统；最后利用MFC设计运行于上位机的客户端界面程序。经过长时间测试运行，该监控系统运行稳定可靠， TCP发送和接收吞吐率达到11.931038 Mbps和8.117624 Mbps。

162.5 MHz high-frequency low-level control system self-developed by Institute of Modern Physics for ADS project took digital technology. All parameters’ reading&writing,including loop parameter setting, open& close-loop operation, and condition monitoring, were achieved through the monitoring system. The system used lightweight client-server working mode that client running in the PC sent command data, server running on high-frequency digital low level system responded instructions to complete parameter monitoring and control. The system consisted of three parts. Firstly, server hardware system was constructed based on Atera Stratix III family of field-programmable gate array (FPGA) development board. Secondly,the server software system was designed based on Micro C/OS II real-time operating systems and lightweight TCP / IP protocol stack, and finally a client PC program was designed based on MFC. After a long test, it was indicated that the monitoring system works properly and stably. TCP sends and receives throughput reached 11.931 038 Mbps and 8.117 624 Mbps.
