【摘要】 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。更多还原

【Abstract】 DAS-1 Dynamic Signal Analysis and Fault Diagnosis System,based on inport technology and CDMS system(completed in 1989),is developed in colour display and in Chinese explanation.This paper presents the de-sign idea,the functions and,especially,the main features in details of DAS-1 system through followingeight fields:Colour Chinese display and window technique;Multi-pass-band band-pass filter;Off-line analy-sis with anti-confusion filter,Improvement of the speed and accuracy of FFT and spectrum analysis;High-accuracy time and RPM measuring;High-speed rotative velocity tracking filter;Cursor in waterfall spec-trum display;And high-speed mode animated display.更多还原
