摘要
针对工厂应用的需求,为提高用电的安全保障设计了一款多功能、智能化电力测控仪。以TMS320F2812 DSP和LPC2294 ARM双嵌入式处理器为系统核心,结合高速同步AD转换器、并行双口RAM等硬件,以及分层次优化设计的驱动程序和应用程序,实现了电量参数的实时测量、分析计算、LCD显示、报警处理、故障快速信号输出、波形录波、历史记录,以及数据U盘转存等多种功能。
According to the using requirement in factory, an intelligent multi-function electric instrument is designed in order to improve the safety in power using. Two embedded processors, a TMS320F2812 DSP and a LPC2294 ARM, are the system core. Together with the hardware of high-speed simultaneous-sampling AD converter, parallel dual-port RAM and so on, the driver program and application program are designed optimally by layering. It is achieved that the electric parameter measure, data calculation and analysis, LCD display, alarm processing, fast signal output when accident happens, wave record, history data store and data re-store to U- disk. etc.
