According to the signal features of various automatic block systems , a signal singularity detection method based on the wavelet analysis technique is adopted in this paper to carry out singularity detection for the data recorded by the cab signaling recorder 摘要根據(jù)鐵路目前各種自動閉塞制式的信號特點,利用基于小波分析技術的信號奇異性檢測方法,通過機車信號記錄器數(shù)據(jù)分析處理軟件對機車信號記錄器所記錄的波形信號進行奇異性檢測。
The apparatus , with the specialities such as miniature , automation , flexibility , and individual - computer managing has become the developing trendof the testing equipment today . based on analysis of the characteristic and the system structure of the visual instrument , the paper has studied the design idea of it , put forward the exploiting methods of the visual instrument based on the object - oriented technique , exoatiated on the technique kernel of design the visual instrument under windows environment , designed a typical visual instrument " vis - 1 signal - analyzing and wave - displaying system " , which integrates multi - function instruments such as general oscillograph and ulf oscillograph real - time signal recorder wave and frequency - pedigree analysis instrument . the system has more excellent functions and characteristics than traditional instruments 本文研究了虛擬儀器系統(tǒng)的設計思想,在分析虛擬儀器系統(tǒng)的特點及其體系結構的基礎上,提出了基于面向對象技術的虛擬儀器系統(tǒng)開發(fā)方法;闡述了windows環(huán)境下實現(xiàn)虛擬儀器的技術要點;實現(xiàn)了一個典型的虛擬儀器系統(tǒng)“ vis ? 1信號示波分析系統(tǒng)” ,該系統(tǒng)集普通示波器、超低頻示波器、存儲示波器、瞬態(tài)信號記錄儀、波形及頻譜分析儀等多種儀器功能于一身,并具有許多傳統(tǒng)儀器難以達到的優(yōu)越功能和性能。
