基于TCP/IP新型高性能网关的设计与实现

针对传统工业现场总线连接方式成本高、开发周期长的不足,设计出一种可以桥接不同现场总线网络的多总线接口经济型嵌入式工业网关.该设计经过对TCP/IP协议栈的裁剪,同时兼顾现场通信的实时性和可靠性要求,实现了多种不同接口设备的统一管理.实验证明,该系统不仅能满足普通网关的功能,而且扩展性强,维护方便,经济实用,具有很大的发...

Design and implementation of new high performance gateway based on TCP/IP

Because the traditional industrial fieldbus connections cost is high,and the development cycle is long,this paper designs a kind of economical multi-bus interface embedded industrial gateway,and it can bridge many different fieldbus networks.Through the cutting of TCP/IP protocol stack,and in view of the real-time and reliability requirements of on-site communications,this design achieves the centralizationg of management of different interface devices.Experiment results show that the system not only can satisfy the function of common gateway,bus also is extensible,easy to maintain,economical and practical,having a very big development space.
