摘　　要：针对有线现场总线网络的弊端及异构网络中节点之间通信接口庞杂问题,给出了VxWorks下现场总线网络与无线以太网融合的方法。利用EtherHook机制实现了不依赖于TCP/IP协议数据获取,简化了现场总线无线接入的转换装置,提高了信息采集的实时性;上层提供统一通用可扩展通信接口,应用和设备独立,便于系统开发、维护、升级和扩展。解决方案具有通用性,提高了系统实时性能、软件开发效率和代码的可重用性,同时可以推广到其他的系统。For the defects of cable fielbus network and the complexity of communication interface between the nodes among the heterogeneous network, a method of amalgamation between fieldbus and wireless ethernet under VxWorks is provided. Using EtherHook, the data acquisition is independent of TCP/IP protocol, the transition equipment is simplified, and the real-time quality of information acquisition is improved;the unified and scalable communication interface of application layer and the independency of application maintenance, upgrades as well as extension of system. Solutions are system,the efficiency of software development and the reusability of the other system. and equipment is convenient for development, universal,and improve the real-time quality of code, and the method can be easily generalized to
