  1. The main achievements are as follows : the theory models of defect mfl field are set up ; based on the magnetic dipole model and finite element model, the distribution of defect mfl field is simulated in the dissertation ; the component of flux density ( magnetic filed ) parallel to the surface of pipe is detected by a circumferential array of hall probes ; the factors including defect geometry parameters, defect surface angle and shape, pipe material, field intensity, vehicle velocity, background magnetization, operating pressure and remanent magnetization and so on influence the mfl signal characteristics

    採用霍爾元件作為缺陷漏磁檢測傳感器,獲得管道軸截面漏磁場切向分量的漏磁;研究了缺陷外尺寸、缺陷傾角和狀、管道材質和磁化強度、檢測儀移動速度、管道背底磁場、管內壓力和剩磁對漏磁的影響。提出了各通道增益放大、各路漏磁離調整、微分、數字濾和平滑等漏磁預處理方法;分析了等空間采樣的漏磁換為等時間采樣的必要性,研究了漏磁的小去噪方法。
  2. On the basis of previous work, we developed a new data processing system by use of dsp & oop. the new system overcame the problems existed in the old data processing system successfully, such as the bug which cause program dead loop when the data is too long, and the frequency leak due to principle limit of fft filter. in addition, we eliminated the measurement error brought on by phase warp

    我們在前人的工作基礎上,利用現代數字處理技術和面向對象的軟體開發技術,統一了彈上黑匣子數據處理系統的操作平臺,完善了速、掃描角測試數據處理系統,修正了原有處理程序中的因數據長度過長而導致程序死鎖的bug ;利用有限沖擊響應( fir )濾器,在濾去噪聲的同時,有效地解決了矩窗fft濾的頻譜泄漏問題;另外還解決了因相位差而導致的測試誤差。
