摘要
现场总线作为一种开放的、全数字化、双向、多站的通信总线,近年来得到了迅猛的发展和应用。在电力自动化领域,现场总线技术的应用已成为一种发展趋势。对于目前国际上多种总线标准并存的局面,文章对主要总线标准进行了分析比较,着重介绍了CAN总线的技术特点,提出了一种基于CAN总线的智能配电系统实现方案。
Fieldbus is a kind of communication system with opening, numerical and with multi-station. It is developed rapidly and applied in industry very widely in recent years. The application of fieldbus technology have been a trend of development in the electric distribution automation. According to the coexisting situation of multiple fieldbus standard, this paper analyses the main fieldbus standards and introduces, the technical character of CAN(controller area network), then proposes a new scheme of intelligent electrical distribution system which based on CAN fieldbus.
