摘要
为实现不同现场总线之间的通信和提供统一的设计模式,达到屏蔽现场总线异构性的目的,对多种现场总线集成环境下不同总线之间的通信进行了研究,建立协议栈模型实现了协议转换网关的通用化设计。与传统的协议转换方式相比,不再局限于一对一的转换,具有与对象位置、通信协议的无关性,提高了系统的扩展性和对不同总线的兼容性。
In order to implement the communication of various kinds of fieldbuses and supply the uniform design model so that the heterogeneity of the fieldbuses can be shield, the communication under fieldbuses integrative network is researched and the protocol stack model is built to implement unification design of intercormect gateway. Compared with old conversion method, it＇s not limited to one- to- one conversion, and independence of the object location and communication protocols, which improves system＇s angment ability and compatibility for various kinds of fiddbuses.
