Abstract: In order to implement the interoperation of the fieldbus and supply the uniform access interfaces for the users as to shield the heterogeneity of the different fieldbus, the real-time fieldbus integrative network based on ACE and TAO is researched and implemented so that various kinds of fieldbus protocols can be converted to each other and transmitted in Ethernet. The network has the capability of real-time scheduling. Compared with the conventional devices, it is not limited to one-to-one conversion, and independent of the object location, programming language, OS platform and communication protocols.

Key words: integrative network, protocol conversion, interoperation, TAO, fieldbus

摘要： 为了实现不同现场总线的互操作以及为用户提供统一的访问接口，达到屏蔽各种现场总线异构性的目的，该文提出了基于自适应通信环境ACE和实时中间件TAO的现场总线实时综合网络系统，实现了现场总线协议之间的相互转换和在以太网上进行统一传输，具有实时调度的能力。与传统的协议转换设备相比，不再局限于一对一的转换，具有与对象位置、编程语言、操作系统、通信协议的无关性。
