The Development Of Breaker Industry Ethernet Data Adapter Based On Embedded System

The breaker Ethernet Data Adapter is the key equipment of the industry Ethernet in Low-Voltage distributes system. The main of low-voltage power intelligent industry control system is fieldbus in China at present. But with the popularity of industry Ethernet, the use of industry Ethernet technique in low-voltage electrical industry marks the level of autoimmunization. So it is the only way to devise an Adapter that can communicate the fieldbus unit and industry Ethernet.On the papers, it is made out the research and development on industry Ethernet device with the international standard about industry Ethernet protocol MODBUS/TCP as well as the research includes international standard about industry Ethernet and networking technology of industry Ethernet.The research of Breaker Ethernet Data Adapter based on Embedded System is the kernel of this papers. High-grade 32-bit ARM embedded MCU is adopted in this adapter, and Ethernet driver, serial driver, application are managed uniformly by Nucleus plus RTOS, implementing system interactive accessing via embedding Web Server. The network security is improved by adding user account system and IP address grant service. At the same time, through adopting scan function and Double-Port that is server port and client port, the real time characteristic and reliability of network are improved, which is the characteristic of this adapter.This item is one part of industry intelligent power distribution system in Changshu Switchgear Mfg.co.Ltd. They have made a prototype successfully when simulation.
