Implementation of Embedded Ethernet Access for Power Quality Monitoring System
HE Bing-nian · Journal of Hubei University of Education · 2008
With the development of society,power quality is paid more and more attention.To stick up for the legal interests of electricity departments and users indeed and to raise the power quality of power grid,the inspection and management of the power quality must be strengthened.This paper puts forward a scheme of intelligent instrument' s embedded ethernet access based on DSP TMS320F2812 and LAN91C111 of SMSC company.Especially μC/OS-Ⅱreal-time system and LwIP protocol stack are transplanted to processor DSP.The design realized by single chip processor and network card chip has low cost,high-speed transmission performance and some other characters.It provides transparent data communication between intelligent instrument and distant terminal through Ethernet.
