基于短时傅里叶变换的船舶电力系统多通道实时数据采集处理装置的研究OA

In this paper,a multi-channel real-time data acquisition and processing device is designed based on the Short-Time Fourier Transform(STFT)method,and a physical platform for testing the performance of the device is constructed.The actual operation results of the platform demonstrate that the design and functional theory analysis of the multi-channel real-time data acquisition and processing device are completed,and a physical test platform is constructed.The data acquisition function,data processing function and spectrum analysis function of the acquisition system are tested and verified by the physical test platform.After many tests,the data acquisition and processing device has good stability and reliability.This device can better meet the application requirements of big data acquisition and real-time analysis and monitoring of new ship power system.
