Profibus and CAN bus are two kinds of widely used field bus in the industrial control field. However, this two bus protocol conversion devices are not introduced on the market, it can not meet the needs of users. Therefore, the design of a Profibus and CAN protocol translation ngateway is very important. By comparing the OSI reference model, the same points of Profibus and CAN bus can be found, their communication model structure is streamlined by the OSI model, they are only three layers, which makes it possible to interconnect them. This paper designs an embedded protocol conversion gateway, S3C2410 processor is used as main controller, SPC3 and SJA1000 are selected as Profibus and CAN protocol chips. The design has realized Profibus and CAN bus protocol conversion, using this gateway in industrial field can bring certain economic benefits for the enterprise.

The differential buses such as RS485 and CAN bus play an important role in industrial control field. In order to make the bus work properly in an extreme environment, this paper proposes a kind of ring topology of bus, by using multiple nodes and redundant method to enhance the reliability of communication of bus. On the other hand, by optimizing the strategy of communication, the efficiency of communication is improved remarkably. And using K/N(G) vote system model to demonstrate the reliability of some methods by calculation. Finally results validate that this new type of ring topology of double circuit with multiple nodes bus possesses good performance in reliability.

A new local area network (LAN) concept designed for educational purposes is proposed based upon the standard RS232 protocol. The concept enables students to gain hands-on experience of all seven open system interconnection (OSI) layers. The proposed approach to teaching computer networks has proved very popular with students. At the same time students' comprehension of basic OSI concepts has improved considerably.
