Inspecting centerline positioning for shaft system and rudder system before boring 轴、舵系镗孔前中心线定位检查。
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 本论文深入学习了无线定位的技术理论及体系结构,掌握了基于cdma网络的无线定位技术gpsone ,在此基础上,将其与业务相结合,提出了位置服务本地接入子系统平台,并给出其设计的模型结构,解决了降低业务接入门砍的技术问题,并结合开展业务模式的分析验证了位置服务本地接入子系统的有效性。
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 本文进行的主要研究工作有: 1解决柱式容器检测中传感器排布要求较严格的问题,开展任意三角形网络排布检测技术与线定位技术研究,首次提出了利用字符串格式判断线定位阵列有效性的判别方法,并解决了任意三角形定位中存在的定位阵列判断,伪定位的剔除,重复定位的避免等一系列问题; 2利用平面任意三角形定位方法开展常压立式储罐罐底缺陷定位技术研究,提出了全新的定位阵列有效性判断、定位点的有效性判断方法;以及顶点声源和边界声源的处理办法。
