摘要
目前,世界上各大加速器广泛采用基于以太网的分布式控制系统组态软件包EPICS构建控制系统。EPICS早期版本是基于实时操作系统VxWorks发展起来的。EPICS国际合作组正致力于支持源码开放,免费的操作系统RTEMS,并准备将RTEMS推广到EPICS3.14新版本中。文章阐述了RTEMS的发展、特点,对比了几种常见的实时操作系统的性能,建立了基于Motorola MVME5500的RTEMS操作系统以及EPICS在RTEMS上的应用实例。
At present, in the accelerator field all over the world, the control system is established with EPICS, which is a configuration software package based on Ethernet and distributed control system. Early version of EPICS was developed based on VxWorks. Now, EPICS international collaboration group is dedicating to supporting open source, free RTEMS, and extending RTEMS into the newer version of EPICS3. 14. The paper illustrates the development, characteristic of RTEMS, compares the performances of several ordinary RTOS, builds RTEMS operating system based on MVME5500, and finally presents an EPICS application example on RTEMS.
