DAS-1动态信号分析与故障诊断系统是我们在借鉴消化吸收引进技术的基础上,对1989年推出的“CDMS 信号处理、故障诊断及振动分析系统”做大规模改进而研制成功的新一代彩色汉化系统。本文着重介绍了系统的功能和设计思想;并且从彩色汉字显示和窗口技术,多通带带通数字滤波器的设计和实现,带数字抗混滤波的离线回放分析功能,提高软件FFT 和谱分析速度和精度的方法,高精度的时间和转速测量新技术,快速转速跟踪滤波方法,三维谱阵的光标显示技术和高速模态动画显示等八个方面论述了其技术特点。
DAS-1 dynamic signal analysis and fault diagnosis system is a new generation of color that we have successfully developed on the basis of large-scale improvement of “CDMS signal processing, fault diagnosis and vibration analysis system” launched in 1989 based on the technology of digestion and absorption absorption Chinese system. This article focuses on the system functions and design ideas; and from the color display and window technology, multi-pass band passband digital filter design and implementation, with digital anti-aliasing filtering offline playback analysis capabilities to improve the software FFT and spectral analysis Speed and accuracy, high-precision time and speed measurement of new technologies, fast speed tracking filter method, the three-dimensional array of cursor display technology and high-speed modal animation display eight aspects of its technical features.
