现场控制领域进展

Evolvement of Industrial Automation

对现场控制领域的进展进行了综述。它包括以智能传感器为代表的智能现场设备及仪表,以FF总线为代表的现场总线和开放式现场总线控制系统,以及正日益升温的工业以太网等,文章分别介绍了他们的概念、特点、现状及发展趋势。在与传统现场总线的对比中,以太网显示出的明显优势证明它是未来控制网络的最佳解决方案,但是它并不会马上取代全部现场总线,因为它们之间还不能完全替代,在较长的时间内,可能是二者共存的局面。

The evolvement of industrial automation is introduced. Its main contents include intelligent device and instrument, fieldbus and industry Ethernet in open industrial control system based bus. Respectively theirs basic notion, character, current status and future are illustrated. In comparison with traditional field-bus, Ethernet is dominant, and possibly it is the optimal solution to future control network. However, Ethernet will not replace all Fieldbus at once and there is possible a concomitant conjuncture of them in a long time.
