【摘要】 现场总线是当今自动化领域技术发展的热点之一,被誉为自动化领域的计算机局域网。它的出现,标志着工业控制技术领域又一个新时代的开始,并将对该领域的发展产生重要影响。 CAN总线属于现场总线技术的一种。是目前流行的现场总线控制系统之一,也是到目前为止唯一有国际标准的现场总线。与一般的通信总线相比,CAN总线的数据通信具有突出的可靠性、实时性和灵活性,同时具备了现场总线的优点。 本课题的研究主要针对现场总线中的CAN总线技术进行深入的了解,开发一种基于CAN总线的现场控制智能节点和智能适配卡,并对所涉及的有关问题进行探讨。更多还原

【Abstract】 Fieldbus is one of the hotspots of the development of automatization technology; it’s looked as local computer network in the field of automatization. Its apperance is the symbol of a new age of industry control technology, and impacts the development of this field deeply.CAN bus is a kind of Fieldbus, it is one of the popular Fieldbus control system, and it is also the only Fieldbus which has national standard. Comparing to normal communication bus, the data communication of CAN bus has excellent characters of reliability, real-time and flexibility, and the strongpoint of Field bus.The reaserch of this thesis mainly aim at the technology of CAN bus of Fieldbus, and deplored a kind of aptitude field control interface and aptitude adaptor base on CAN bus. What’s more, this thesis has discussed the problem involved deeply.更多还原
