在研究了嵌入式操作系统uClinux的基础上,构建了以S3C44BOX为CPU、CS900A为以太网控制器的智能电气设备以太网接入模块,提出了以此作为变电站间隔层通信接口的变电站自动化系统通信方案。该方案能够提高现有变电站自动化系统通信的速度和可靠性, 并能升级成符合IEC61850体系的变电站自动化通信系统。
Based on the study of embedded operating system uClinux, an Ethernet access module of intelligent electrical equipment with S3C44BOX as CPU and CS900A as Ethernet controller is constructed. The substation automation system communication Program. The program can improve the speed and reliability of existing substation automation system communications, and can be upgraded to substation automation communication system in line with IEC61850 system.
