The technology on state detection and trouble diagnosis of engineering machinery
工程機械狀態檢測與故障診斷技術 -
In large rotating machinery using filmatic bearing ( turbogenerator, air compressor, etc. ) there is a potential trouble from impefect installation or running conditions, a metals " contact between rotors and shells. the trouble is usully called rubbing. the advantage of ae technologe in the rubbing diagnosis and early detection is showed. instead of classical ae characteristic parameters ( counts, amplitude, energy, duration and the other ones ) a new feature extraction by frequency analysis of ae envelop signals is discussed. both research of ae process and field experements indicate that periodic components in the envelop spectrum related to rotational speed increase evidently at the beginning of rubbing production, hence are highly sensitive to the rubbing fault diagnosis. according to the new design an acoustic emission equipment for the rubbing diagnosis named buaa ae testing system is developed and described
汽輪發電機、空氣壓縮機等採用油膜支撐的大型轉動機械，由於安裝或運行中的原因，在轉子旋轉過程中，可能和器壁發生輕微的摩擦和碰擊，簡稱碰摩.聲發射技術在碰摩發生特別是故障早期診斷上有優越性.本系統的特點是沒有沿用傳統的計數、幅度、能量和持續時間等聲發射特性參數，而是在聲發射包絡信號的頻率分析中進行特徵提取.聲發射發生的過程分析和現場試驗都表明這種方法對碰摩檢測很敏感，在碰摩發生的起始階段，包絡譜中與轉速同步的周期性分量顯著增加.根據這種新的設計思想自行研製了buaa碰摩聲發射檢測儀並對此作了介紹 -
This paper has discussed the network mode question of the computer at first, studied and set up emphatically the information management system for the locomotive detections under the structure network environment of server of the client, and perfectly realized man - machine interaction combined the relation database management system and object - oriented programming language c + + builder ; we have also actualized non - standard device detect and control test bed and present a method that will enable the test bed to apply in this the information management system for the locomotive detections ; at the same time, though studying this system, we have proposed the method to achieve certification of quality control for the locomotive coming in and going out section, auto - maintain for the locomotive detection plan and auto - statistic and auto - analysis for the part trouble of the locomotive
應企業要求和我們的研究實踐，我們提出了數字化機務段概念，並且開發了機車檢測管理信息系統。本文首先討論了計算機網路模式問題，著重研究並建立了客戶機服務器結構網路環境下機車檢測信息管理系統，結合關系數據庫管理系統和面向對象編程語言c + + builder較好地實現了人機交互；實現了基於pc104總線的非標設備測控試驗臺，提出了將試驗臺應用於該檢測管理信息系統的方法；通過本系統的研究，提出了機車出入段的合格證控制、機車檢測計劃的自動維護以及機車部件故障的自動統計分析的實現方法。 -
However, because the automobile breakdown is characterized by suddenness, comprehensiveness and difference, at the time of failure detection, we still need concrete analysis of concrete conditions, that is, we should choose appropriate detection facilities or testing tools with correct logic fault analysis, and then establish the data of failure detection and diagnosis, by which we can locate the failure and carry out trouble shooting accurately and promptly
所以在檢測故障時，我們仍需要具體的情況具體分析即選擇適當的檢測設備或檢測工具輔以正確的故障分析邏輯，並在此基礎上建立故障檢測與診斷數，才能準確、及時地對故障進行定位與故障排除。汽車智能檢測系統的研究與開發目的是為了解決汽車故障的智能化檢測，而現代汽車故障診斷的基礎是汽車用傳感器的測試。 -
However, high dimension and large data amount of hyperspectral images bring trouble to target detection. what ’ s more, traditional segmentation and detection algorithms for single images are inefficient for hyperspectral images
然而高光譜圖象大數據量、高數據維給目標檢測應用帶來了極大的困難，傳統的基於單幅圖象的分割、檢測演算法已經不適應于高光譜圖象的小目標檢測。
