Inspecting centerline positioning for shaft system and rudder system before boring 軸、舵系鏜孔前中心線定位檢查。
This paper researches the technique of mobile orientation and the gpsone technique based on cdma , based on it linking the technique and application , the paper puts forward location based service ( lbs ) flat roof in order to falling the application developing doorsill . this paper gives the design patterm . and combining the patterms of application validates the validaty of location based service system 本論文深入學習了無線定位的技術理論及體系結構,掌握了基于cdma網絡的無線定位技術gpsone ,在此基礎上,將其與業(yè)務相結合,提出了位置服務本地接入子系統(tǒng)平臺,并給出其設計的模型結構,解決了降低業(yè)務接入門砍的技術問題,并結合開展業(yè)務模式的分析驗證了位置服務本地接入子系統(tǒng)的有效性。
The research works finished in this paper are listed below : 1 . solving the problem in testing of cylinder vessels that the sensors disposition is very rigorous , carrying out study of freewill triangle network orientation and linear orientation , bringing forward the discriminance which distinguish the validity of orientation array using character string method the first time , at the same time , solving the problems that judgement of orientation array , elimination of camouflage location , avoidance of repeat location , etc . 1 ' . carry ing out the study of the orientation of defects in stand lank floor with the method of freewill planar triangle orientation , advancing bran - new discriminance on the validity of orientation arrays , orientation points , and the disposing means of the acoustic sources near sensors and those near common border 本文進行的主要研究工作有: 1解決柱式容器檢測中傳感器排布要求較嚴格的問題,開展任意三角形網絡排布檢測技術與線定位技術研究,首次提出了利用字符串格式判斷線定位陣列有效性的判別方法,并解決了任意三角形定位中存在的定位陣列判斷,偽定位的剔除,重復定位的避免等一系列問題; 2利用平面任意三角形定位方法開展常壓立式儲罐罐底缺陷定位技術研究,提出了全新的定位陣列有效性判斷、定位點的有效性判斷方法;以及頂點聲源和邊界聲源的處理辦法。
