摘　　要：现场总线实验涉及多种总线协议和嵌入式专业知识。为使学生掌握ProfiBusDP和Mod us两种总线协议通讯的实现方法、掌握两种总线之间数据交换的实现方法以及掌握嵌入式μC/OS-II操作系统下两种总线协议及网关的实现方法,设计实现了一种现场总线实验平台。主要介绍实验平台的硬件环境,软件基本框架,网关驱动程序的设计流程和测试方法。该实验设计在实验教学中,使嵌入式操作系统和现场总线的协议网关相结合,有助于培养嵌入式总线开发能力的专业型人才。ln order to make the students master the implementation method of ProfiBusDP and ModBus bus protocol communi-cation, grasp the data exchange′s implementation method between the two bus and master the two kind bus communica-tion and the gateway′s implementation methods under the embedded μC/OS-ll operating system,a kind of profitbus exper-iment platform are designed.This paper mainly explains the experiment′s hardware environment,software framework,design process and test method of the gateway driver.
