基于Corba总线的控制系统技术改造
Technology Update of a Control System Trough Corba Bus
摘要：
经过10多年的活动，FTU（弗拉斯卡蒂托卡马克升级）必须面对利用新的硬件和软件技术节省所有投资的问题。因此，例如，20年前的西屋PLC（仅通过串行线路通信）必须保持运行，而基于网络的工具必须发布用于计划监控目的。CORBA总线已被证明是建立新旧硬件和软件块之间通信的答案。在FTU上，控制系统基于Basestar，一个Digital/Compaq软件套件。我们将描述如何通过Java图形工具，LabView和原则上接受外部例程的任何软件包访问Basestar的实时数据库。在数据采集领域，Camac串行高速公路驱动程序仍然通过CORBA总线集成在新的体系结构中
英文摘要：
After more than 10 years of activity, FTU (Frascati Tokamak Upgrade) has to face the problem of taking advantage of the new hardware and software technology saving all the investments yet done. So, for example, the 20 years old Westinghouse PLCs (communicating only through a serial line) have to be leaved in operation while a web-based tool has to be released for plan monitoring purpose. CORBA bus has been demonstrated to be the answer to set up the communication between old and new hardware and software blocks. On FTU the control system is based on Basestar, a Digital/Compaq software suite. We will describe how the real time database of Basestar is now accessed by Java graphic tools, LabView and, in principle, any package accepting external routines. An account will be also done in the data acquisition area where a Camac serial highway driver has been integrated in the new architecture still through the CORBA bus
