摘要
为满足IEC61850标准对变电站自动化系统及智能设备提出的互操作性、实时性和稳定性要求,将32b处理器ARM(advancedRISCmachine)及嵌入式操作系统uClinux引入封闭式组合电器(GIS)的在线监测领域。根据GIS在线监测的需要,设计了以太网通信和CAN(controllerareanet-work)总线通信的硬件电路及软件。应用测试结果表明:基于ARM和uClinux中TCP/IP协议栈的以太网通信,可以实现GIS在线监测系统的互操作性,并保证在通信功能上的长期稳定性;以ARM为核心的嵌入式系统硬件,可以保证监测装置的稳定性、实时性和可扩充性。故基于ARM和uClinux的GIS在线监测系统可以满足IEC61850标准对互操作性、稳定性和实时性的要求。
A 32-bit microcontroller advanced RISC machine （ARM） with the embedded operating system uClinux was used for an on-line monitoring system for gas insulated switchgear （GIS） to meet the IEC61850 standard for automatic power station operation. The hardware and software were designed for the on line GIS monitoring system which used the Ethernet and CAN （controller area network） for communication. The network based on the ARM and the TCP/IP stack of uClinux provides the on-line GIS mornitoring system with stable communications and interchangeability. The ARM kernel in the embedded system provides a stable on-line monitoring system with real-time processing capability and extendability. Therefore, the on-line GIS monitoring system based on the microcontroller ARM and the embedded uClinux operating system effectively meets the requirements of the IEC61850 standard.
