摘要
为了满足变电站对电力参数采集的实时性与可靠性要求,提出并设计了一种基于嵌入式技术的高速数据采集模块。该模块以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和开关量信号的采集与处理。并可通过RS-485总线与主CPU模块通信完成数据存储与传输、异常事件检测等功能,也可通过本地人机交互接口对模块进行维护和升级。
In order to meet the real-time and reliability requirements of power data substation,this paper introduces the design and realization of intelligent modules which based on LPC2138 ARM microcontrollers.They using hardware synchronization and software error correction to gather and process the data of power grid,it can also be connected to the computer control system implementing data storage,transmission and exceptional event monitoring.
