摘要/Abstract

摘要：

介绍智能配变终端的主要功能及优势，提出基于双核微处理器OMAPL138的智能配变终端的设计方案。其中处理器中数字信号处理（digital signal processer,DSP）核实现数据采集、信号处理和实时控制功能；先进精简指令集计算机器（advanced reduced instruction set computer machines，ARM）核则通过嵌入式Linux操作系统实现人机交互、数据存储、通信、安全防护等功能。DSP与ARM分工明确，双方之间可方便地进行数据交互及资源共享，提高了系统的工作效率。终端设计采用了总线接口和模块化技术，具有较好的可扩展性及灵活性，并支持板卡的热插拔，可方便地实现系统的升级。

Abstract:

The key functions and advantage of Rural Intelligent Distribution Transformer Terminal are introduced, and a design scheme is presented based on OMAPL138 dualcore microprocessor. Data acquisition, signal processing and realtime control are realized by digital signal processer (DSP) core, while humanmachine interaction, data storage, communication and security protection are processed by advanced reduced instruction set computer machines (ARM) core through embedded Linux. Tasks are distributed clearly between DSP and ARM, and data exchange as well as resource sharing can be easily implemented within the chip. The design of terminal is based on bus interface and modular technology, which enhances its expansibility and flexibility. Hotplug of daughter boards and convenient system upgrade are supported by the terminal.
