摘要

最近的DIII-D计划升级到6个1mw回旋管，为控制和仪表系统的现代化提供了机会。该系统面临的挑战是允许少数操作员控制回旋管，这些回旋管具有单独的调谐要求，并且来自两家制造商。主用户界面是用美国国家仪器公司的LabVIEW软件编写的。通过LabVIEW接口无法访问的PLC功能由西门子的TISOFT和Ci Technologies的Citect提供。计算机控制系统使用通过以太网连接的计算机来分配控制、状态和数据功能。直接与回旋管系统硬件接口的计算机使用机架安装和坚固的紧凑PCI格式。波形数字化器和定时控制模块，对高压电源、回旋管灯丝升压进行门控，并发送硬件复位和数字化器触发器，也位于紧凑的PCI板条箱中。这些计算机还控制负责形成回旋管脉冲形状、编程扫描线圈波形、设置波导偏振角和检测异步系统事件的硬件。许多控制功能是由plc在计算机控制下完成的。plc负责真空和波导系统、访问联锁、灯丝电源控制、冷却系统联锁、高压电源接口、回旋管油箱油联锁和发射镜控制。

The DIII-D multiple gyrotron control system

The recent DIII-D program to upgrade to six 1 MW gyrotrons presented the opportunity to modernize the control and instrumentation systems. The challenge of the system is to allow a small number of operators to control the gyrotrons, which have individual tuning requirements and are sourced from two manufacturers. The main user interface is written in National Instruments' LabVIEW software. Access to PLC functions not available through the LabVIEW interface are provided by Siemens' TISOFT and by Ci Technologies' Citect. The computer control system uses computers connected by ethernet to distribute the control, status, and data functions. The computers which directly interface with the gyrotron system hardware use a rack-mountable and ruggedized compact PCI format. The waveform digitizers and the timing control module, which gates the high voltage power supply, the gyrotron filament boost, and sends the hardware reset and digitizer triggers, are also located in the compact PCI crate. These computers also control hardware responsible for forming the gyrotron pulse shape, programming the sweep coil waveform, setting the waveguide polarizer angles, and detecting asynchronous system events. Many control functions are handled by PLCs which are under computer control. The PLCs are responsible for the vacuum and waveguide systems, access interlocks, filament power supply control, cooling system interlocks, the high voltage power supply interface, gyrotron tank oil interlocks, and launcher mirror control.

期刊介绍： 19th-Century Music covers all aspects of Western art music between the mid-eighteenth and mid-twentieth centuries. We welcome--in no particular order--considerations of composers and compositions, styles, performance, historical watersheds, cultural formations, critical methods, musical institutions, ideas, and topics not named on this list. Our aim is to publish contributions to ongoing conversations at the leading edge of musical and multidisciplinary scholarship.
