摘要
介绍一种基于DSP和ARM架构的便携式电能质量监测系统的软硬件设计方案。利用TITMS320F2812DSP和高精度数据采集芯片AD7656完成对现场电信号的同步采集和分析计算,DSP通过串口和FIFO与嵌有Linux系统的ARMS3C2440芯片通信,完成分析数据和原始数据的传输,采用大容量存储设备记录存储采样波形和分析结果,通过网络接口上传数据并设置监测终端的运行参数。实验测试结果表明该设计的可行性,该系统满足实时在线监测电能质量的各项指标。
A new design of DSP ＋ ARM portable power quality monitoring device is proposed in this paper. TMS320F2812 DSP and high precision AD7656 are used for power quality data synchronous acquisition.Monitoring values are computed in the DSP, which communicates with ARM S3C2440 embedded with Linux system via serial port and FIFO and transfers power data and computed values. The data are stored in large capacity storage device and displayed in the LCD. The data transmission between PC and ARM is fulfilled by network and the operating parameter of monitoring terminal is set. Feasibility and reliability of the device are validated by experimental test , and the results show that the device is in accord with the electric power quality monitoring standard.
