摘要
为满足WorldFIP设备在现场应用的不同需求,开发了一种新型的可用于各种WorldFIP变送器和执行器上的通用平台。硬件上,该平台主要由ARM7微控制器AT91M40800为核心的CPU模块和WorldFIP从设备通信芯片MicroFIP为核心的通信圆卡等模块构成。软件上,重点给出了VxWorks下的BSP中断连接模块的编写方法和MicroFIP驱动程序的框架。最后介绍了软硬件的调试步骤和经验。实验表明,在此平台上开发的设备能够作为WorldFIP从站良好地运行。
To satisfy the requirement of the filed device based on WorldFIP protocol, a novel WorldFIP slave station platform designed for various WorldFIP transmitters and actuators is developed. The principles, design method and characteristics of hardware and software platform are presented. In hardware, this platform consists of CPU module based on ARM7 microcontroller AT91M40800 and WorldFIP communication round card with core of MicroFIP chip. In software, the design and realization of interrupt connection module...
