继电保护收发信机嵌入式监控组件的设计及实现

摘要

设计了继电保护专用收发信机监控组件.监控组件采用了Samsung公司的ARM9系列芯片S3C2410作为核心处理器,操作系统采用实时可裁剪嵌入式操作系统WinCE.NET,满足现场运行的实时性和可靠性要求.该监控组件通过RS232串口与收发信机的DSP组件通信,可完成对收发信机的工作参数的配置,时钟的读写,及故障事件记录的读取等功能,可实时监测收发信机的工作状态,如:发信电平、收信电平等.同时也给出了监控组件具体的硬件设计、软件设计方法和系统的应用.%A monitor module for dedicated relaying protection transceiver is designed. The monitor module adopts Samsung's ARM9 family chip S3C2410 as its core processor, and it adopts real-time scalable embedded operating system WinCE.NET as its operating system. So, it can meet all kinds of requirements for real-time operating and reliability in the work field. The monitor module communicates with DSP module of transceiver through RS232. It Can perform many functions such as configuration of working parameters, clock modification, and events recording. It also can real-time monitor the transceiver's working state such as sending level, receiving level, etc. The paper describes hardware design, software design, and the application of the monitor module.
