| 摘 要： | 电能质量问题取决于供电方和用电方。为了切实维护电力部门和用户的合法利益,提高电网的电能质量水平,必须加强电网电能质量的监测和管理。采用DSP TMS320F2812和SMSC以太网控制器LAN91C111设计的以太网通信硬件平台,并将μC/OS-II实时操作系统和LwIP协议栈移植到该平台上。利用DSP和以太网控制芯片实现的接入方案具有低成本、高传输率等特点,从而能够将现场测控得到的数据方便快捷地送到异地的管理监控层。

| Abstract: | 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 LAN91C 111 of SMSC company. Especially μC/OS- Ⅱ realtime 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. |
