摘要: 运用数字化处理、计算机网络等先进技术，实现对磁质谱仪的远程控制。简要介绍磁质谱仪工作原理。根据该磁质谱仪系统所包含的设备种类，设计了基于以太网的二级控制结构。实现了各种运行参数的远程调节、状态回读的基本功能，并设置了真空-高压/分析磁铁电源、门禁-高压/分析磁铁电源的安全联锁保护。针对触发控制延时时间在0~20 μs连续可调的极高要求，设计了一套触发束采系统。通过测试，系统获得了满足物理实验需求的谱图。经过数十小时的实验，系统运行稳定、操作性强，很好地满足了用户的实验需求。Abstract: The principle of magnetic mass spectrometer is briefly introduced. According to types of equipment included in the magnetic mass spectrometer, a two-layer structure of control system based on Ethernet is designed. The basic functions of remote adjustment and monitor of parameters and interlock protection are realized. A set of trigger system is designed for a continuously adjustable delay time of 0~20 μs.Through the test, the system has obtained the spectral graph which satisfies the physical experiment requirements. After dozens of hours of experimental test, the system is stable and operable, which satisfactorily meets the user's experimental needs.
