The Research Of Automatically Interpretting Algorithm Based On WinCE In The Acoustic Detection

Accompanying the clipping developing and the practical application of the microelectronic technology,computer technology and embedded technology,new design conceptions and realization methods are carrying out,and have broken through the traditional engineering modes of the detection system.The new generation of embedded nonmetallic supersonic examination system working pattern will be more flexible,simultaneously proposed to the software design a higher requirement,so the embedded software algorithm design will also become the research hotspot.This thesis first introduces the ultrasonic detection technology,then analysis the role of algorithm playing in the pile integrity testing,meanwhile the characteristics of embedded systems software development and the basic flow will be briefed,which provides sufficient theory and preparation foundation for the application of automatic interpretation.Then,after introducing the current status of traditional interpretation algorithm in acoustic detection,the inaccurate results of the traditional interpretation algorithm are analyzed.At the same time,after a lot of reading literature and analyzing the measured data,the characteristics of the acoustic signal transmission in the concrete are studied as a key point,then the main causes of interfering acoustic signal to be correct interpreted are analyzed,thus,the automatic interpretation algorithm has been put forward.The main focus of the study is automatic interpretation algorithm design and implementation . Targeted at the existing interpretation algorithm flaws and shortcomings,it will replace hardware with software to optimize system functions,and help resolving zero drift,residual oscillation, the inevitable signal superimposed and energy absorption in transmission of acoustic,so as to provide highly automated,accurate,stable and reliable automatic interpretation software. Based on the Windows CE operating system,kernel software development and customization is a major difficulty.Firstly the problems,along with the solutions,encountered in the process of realization interpretation algorithm in Windows CE platform are discussed in detail.Secondly,a lot of performance testing and comparison testing are done according to the design of automatic interpretation algorithm.The results have shown that automatic interpretation algorithm has great effecting in the acoustic detection.
