主动反射面是FAST(Five-hundred-meter Aperture Spherical radio Telescope)望远镜的一个重大创新之一,其性能将直接关系到整个望远镜的性能,因此主动反射面的控制需要一个实时高效的控制系统。基于EPICS(Experimental Physics and Industrial Control System)的输入输出控制器(Input/Output Controller,IOC)框架,充分利用EPICS的实时性,根据FAST反射面的控制节点达2 000多个的特点设计了新的记录类型——节点控制器记录,以便于控制器节点IOC的管理以及提高代码的复用,并针对FAST主动反射面密云模型对实际装置进行了仿真、设计和部分测试。
Active reflection surface is one of the major innovations of the FAST (Five-hundred-meter Aperture Spherical radio Telescope) telescope. Its performance will be directly related to the performance of the entire telescope. Therefore, active reflective surface control needs a real-time and efficient control system. Based on EPICS (Experimental Physics and Industrial Control System) I / O Controller (IOC) framework, taking full advantage of the real-time nature of EPICS and designing more than 2000 control nodes based on FAST reflector, Record Type - Node Controller Record to facilitate controller node IOC management and code reuse, and to simulate, design, and test the actual device against the FAST active reflector cloud model.
