摘要
在符合IEC61850标准的变电站自动化系统中,将以间隔层、过程层智能电子设备为代表的嵌入式系统连接到工业以太网中,TCP/IP协议栈的实现是一个关键。为了适应嵌入式系统的软硬件环境并满足实际要求,对标准TCP/IP协议栈进行了裁剪与修改,设计了一种适合32位微处理器的嵌入式TCP/IP协议栈。新的协议栈不仅实现了标准TCP/IP协议栈的主要功能,占用资源少,而且为间隔层、过程层智能电子设备的网络化创造了条件。
When intelligent electronic devices are connected to Ethernet of substation automation system in line with the IEC 61850 communication standard,implementation of TCP/IP protocol stack is a key technology. In order to adapt to software and hardware surroundings of the embedded system and meet its actual requirement,the standard TCP/IP protocol stack need to partly cut and modified,meanwhile,an embedded TCP/IP protocol stack suitable for 32 bits MCU is designed. The new protocol stack not only realizes the main functions of the standard TCP/IP stack,but also occupies fewer system resources. In addition,it is able to provide technologic support for the networking of intelligent electronic devices.
