摘要
为了满足变电力系统对现场交流信号采集的实时性与准确性要求,提出并设计了一种基于ARM的嵌入式高速数据采集系统。该系统以LPC2138微处理器为核心,利用硬件同步与软件纠错相结合的方法实现电力现场模拟量信号的采集与处理;该系统可通过RS-422总线与主CPU通信完成数据的存储、传输与处理;也可通过本地人机交互接口对系统进行维护和升级。
In order to meet the real-time and reliability requirement of AC signal collection in power system, this paper introduces the design and realization of embedded data substation system which based on LPC2138 ARM microcontrollers. It uses hardware synchronization and software error correction to gather and process the analogue data of power grid, and it can also be connected to the computer control system implementing data storage, transmission and exceptional event monitoring.
