| 摘要: |
| 为满足对大型电力设备的远程状态监测和分析要求,设计了以C2000系列DSP-TMS320F2812(简称F2812)为核心处理器的电力设备远程监测分析系统。该系统能完全脱离主机独立运行,利用F2812丰富的外设模块构建了系统的硬件,包括对模拟信号、频率信号、数字信号的数据采集,并具有以太网、RS-232、CAN总线3种通信功能。采集的信号经过DSP的嵌入式有限脉冲响应FIR数字滤波和快速傅里叶变换(FFT),得出信号的无噪声时域和频域数据。利用时、频域数据进行特征提取和分析,得出设备的运行状态和潜在故障信息。测试表明本系统能够实现长时间在线监测,并能正确地识别出故障。 |

| Abstract: |
| To meet the needs of remote monitoring and analysis for large-scale electrical equipment,a remote monitoring and analysis system is designed,which takes DSP TMS320F2812 as its core processor and can run independently without master computer.Its hardware is built with various peripheral modules of TMS320F2812,including the data acquisition of analog,digital and frequency signals and the communication function of Ethernet,RS-232 and CAN buses.The acquired data is processed by FIR(Finite Impulse Response) digi... |
