The Application And Research Of μC/OS-Ⅱ In The Interconnection Between LonWorks And Ethernet

Control network technology has now become the focus of the automatization field with the highly development and inter-penetration of the technology of computer, network, communication and control technology. Nowadays, as a kind of new control system, the Fieldbus control system is the leading force in control field because it has advantage of open, distribution, network and intelligence.The Ethernet is the most widely used network in LAN (local area network), which has the advantage of openness, low-cost, and also widely supported by many company. The interconnection between LonWorks Fieldbus and Ethernet has become a very important aspect in the development of automation of manufactures.The paper discussed the Lon Works Fieldbus, including the features of the software and hardware system and also the advantages in developing products based on LonWorks technology.This paper discussed popular widely used Ethernet technology, including the advantage of the Ethernet used in the control network, and the features of the Ethernet in data transferring is also introduced.This paper discussed the Embedded Operating System μ C/OS- II , and described the using of Operating System on TMS320C32 Processors.This paper also described the design of the adapter between LonWorks and Ethernet and introduced the hardware design and the software design of the adapter in detail.The adapter which makes features of flexibility and low-cost is applicable to various usages and possesses bright future in both development and application.
