摘 要: | 提出了一种针对变速恒频电源电压交流畸变的新的检测方法。文中根据傅立叶变换理论,设计了采用TMS320C32DSP作为CRU、以MAX120作为A/D转换器构成的数据采集系统;探讨了信号采样频率和截取长度的选取;采取了基2的FFT变换算法并给出了软件流程图;本文结果得到了实验验证。

Detection of Extraneous Frequency in VSCF
Electric Source Based on Data Acquisition |
| |
Abstract: | A new method to detect the extraneous frequency in the VSCF electric power source based on data acquisition is discussed. Fourier analysis theory is used as a foundation. The data acquisition system based on TMS320C32 as a CPU and MAX120 as an A/D converter is designed. The frequency and the length of data acquisition are discussed and the flow chart of the program is also given. The data acquisition is verified by experiments. |
