A High-Speed Signal Acquisition and Processing System

该文简要介绍冷却风扇试验台高速信号采集与处理系统的主要特点、基本构成和信号采集与处理能力。

This paper presents an signal acquisition and processing system for fan test station. The system,based on microcomputer without external large-capacity and high-speed storage device, can realize continuous high-speed data acquisition and store. It can perfom a Variety of data processing tasks, such as cxtracted data real-time disply, while the system is collecting data; engineering unit conversion; low-speed data reproduction; FFT; power spectrum analyses; Windowing; curve fitting; graphics display; plot; and so on.
