摘　　要：在实时嵌入式工控领域中,系统的实时性和高可靠性尤为重要。针对实时嵌入式领域中的工业现场分布式控制系统,设计了双冗余热备份PROFIBUS主站仲裁模块,提出了双冗余主站工作保持数据一致性问题以及双冗余PROFIBUS总线的工作与切换方案,并且设计了虚拟双端口存储器通信协议,提高了系统的可用性和可靠性。In real-time embedded industrial control field, the system real-time performance and high reliability are particularly important. This paper focuses on industrial field distributed control systems in real-time embedded field, then designs a dual redundant hot-standby PROFIBUS master station arbitration module, and analyzes solutions for dual redundant master data consistency, as well as dual redundant PROFIBUS switching solutions. In the end, the paper designs a virtual dual port memory communication protocol, therefore improves sys- tem availability and reliability.
