| 摘 要： | 针对标准PROFIBUS-DP从站产品难以集成到现有集散式控制系统的问题,提出了网关解决方案.在对现有网关实现方案进行比较后,选用软核方案,设计了具有热插拔功能且兼容两种实现方案的硬件平台.采用模块化设计思想进行软件架构,应用状态机法实现了"PROFIBUS-DP通信"子功能.从防错设计、纠错设计、故障恢复设计等方面对设计方案中软、硬件可靠性进行了详细分析.针对硬件特性,从调度策略的角度阐述了影响系统实时性的关键问题,并对自主设计主站的难点问题-组态设计进行了说明.该方案支持系统运行过程中动态地增加和删除从站,修改从站配置参数.分析并实验测试了网关的性能参数,网关最高支持3 Mbit/s的通信波特率.实验结果表明,系统性能优越,运行稳定.
