基于ATCA的网络拓扑结构的研究

摘要

With the development of communication technology, high-end numerical control technology, precision measurement technology, there are more requirements for industrial PC of high speed data exchange, system redundant backup, highly stability, intelligence management and so on. Based on the limit of general-purpose CPCI parallel bus structure in communication field nowadays, the elements, features and applications of new general industrial control computer dual star, dual-dual star and full mesh topology structure on ATCA of new generation industrial control computer are focused on, and its future development is also presented.%随着通信技术、高端数控技术、精密测量技术的发展,人们对于工业计算机的高速数据交换、系统冗余备份、稳定性、智能管理等要求越来越高.在探讨目前通信和测量领域广泛应用的CPCI并行总线架构局限性的基础上,着重研究了基于新一代工业计算机架构--ATCA的双星、双-双星、全网状网络拓扑结构的原理、特点和应用,并对其未来发展做了展望.
