基于嵌入式系统的电力光纤信号测试仪的设计与实现

摘要

In order to realize the real-time monitoring and testing of the substation system , quickly grasp the operating status of the substation equipment. This paper designed a kind of electric power optical fiber signal analyzer based on embedded system. The equipment based on the IEC61850 standard , combined with the embedded system hardware features , complete peripheral circuit and optical signal conversion, FT3 decoding module design, drive the design of peripheral interface software, realization of substation system Ethernet transmission standard IEC61850 sampling value message and GOOSE message access, etc. based on the analysis, real-time control system running state%基于掌握变电站设备的运行状态,对变电站系统实现实时监控的目的,本文研究设计了一种基于嵌入式系统的电力光纤信号分析仪.系统基于IEC61850标准,硬件上结合嵌入式系统特点,完成外围电路及光信号转换、FT3解码等模块设计,软件上完成外设接口的驱动设计,实现对变电站系统以太网中传输的基于IEC61850标准的采样值报文及GOOSE报文等的获取、解析,实时掌握系统运行状态.
