Industrial Ethernet Real-time Studies And System Design

In this thesis, we made an overview on the history and the latest achievements of industrial network and compared Industrial Ethernet with DCS and Fieldbus, two other popular network control systems. We also introduced the history and the development of Industrial Ethernet and made a discussion on the advantages and disadvantages of Industrial Ethernet for industrial control. Then we analyzed the real-time performance of Ethernet and presented several solutions to advance the real-time performance by using the up-to-date technology such as full-duplex switch Ethernet, VLAN, QoS and IPv6. Based on the characteristic of Network Management System, we discussed the architecture of Industrial Ethernet Network Management System, analyzed the redundancy design of the core layer and the distributed layer of Industrial Ethernet and provided the schemes of redundancy design. At the same time, we discussed system framework design of Industrial Ethernet, provided the ideal design mode and pointed out the direction in the future: hybrid system of Industrial Ethernet. At last, we did some research on the wide application field of industrial Ethernet and developed two applications: Embedded remote water level control system and Network meter reading system.
