摘要
该控制器的设计是在国内某大型钢铁公司技术改造的背景下提出的。控制器硬件平台以GE—Fanuc 90-70PLC为基础,使用开放的VME总线结构。嵌入式控制器采用德国MEN公司的基于PowerPC的A12单板计算机以及Vx-Works高性能实时嵌入式操作系统。文中详细分析了Vx-Works及硬件设备的特点,给出了控制器设计的具体方案和软件开发的方法。该控制器具有很强的通用性,能够满足不同用户的使用需求,特别适合于要求快速控制的领域。
The controller is developed in the reconstruction of some domestic Iron and Steel Corporation. The hardware platform adopts the GE-Fanuc 90-70PLC chassis, in which VME bus is used. The controller is based on the VxWorks, which is a powerful real -time operating system. Motorola PowerPC MPC8245 is used as the controller' s CPU. In this paper, the characteristics of VxWorks and hardware adopted are analyzed in detail. In addition, the hardware configuration of the controller and the method of software developing are both elaborated.
