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(xué)習(xí)了無線定位的技術(shù)理論及體系結(jié)構(gòu),掌握了基于cdma網(wǎng)絡(luò)的無線定位技術(shù)gpsone ,在此基礎(chǔ)上,將其與業(yè)務(wù)相結(jié)合,提出了位置服務(wù)本地接入子系統(tǒng)平臺(tái),并給出其設(shè)計(jì)的模型結(jié)構(gòu),解決了降低業(yè)務(wù)接入門砍的技術(shù)問題,并結(jié)合開展業(yè)務(wù)模式的分析驗(yàn)證了位置服務(wù)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(jìn)行的主要研究工作有: 1解決柱式容器檢測(cè)中傳感器排布要求較嚴(yán)格的問題,開展任意三角形網(wǎng)絡(luò)排布檢測(cè)技術(shù)與線定位技術(shù)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(fù)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(chǔ)罐罐底缺陷定位技術(shù)研究,提出了全新的定位陣列有效性判斷、定位點(diǎn)的有效性判斷方法;以及頂點(diǎn)聲源和邊界聲源的處理辦法。
