【摘要】 随着科学技术的发展,人们对定位技术的要求日益提高,然而由于接收机接收的是卫星信号,因此接收机必须放在露天的没有高大建筑物的地方,这就给用户的使用带来了一定的限制。因此在此将尝试设计一种蓝牙相对定位系统,即把最新的蓝牙技术应用于定位系统,同时与移动通信技术相结合,达到定位的效果。论文的选题来源于国家重大创新计划项目。由于蓝牙技术的出现和发展,代替了繁琐的电缆,而且由于大批量的生产导致GPS(全球定位系统,Global Positioning System)芯片的成本不断的下降,所以开发基于蓝牙的相关应用成为一个非常实用的课题。本系统基于嵌入式linux操作系统,借助于GSM网络进行定位信息的传输,结合了最新的蓝牙技术,同时采用Microwindows和FLTK来实现系统的图形用户界面(GUI,Graphical User Interfac)的设计。本文分析了各种最新的定位技术,最后选用丽台公司的9553X,然后采用WAVECOM公司的Q2406B模块搭建了一套蓝牙GSM系统,通过它来实现GPS信息的共享,采用TI公司的OMAP1510开发板作为嵌入式系统的硬件平台,从而在嵌入式linux系统中实现了GPS定位信息的解码、显示,以及根据GPS信息的变化来实现运动方向的判断和显示、运动速度的计算和相对定位的实现。实践证明,把GSM和GPS技术结合进行定位是可行的,同时采用蓝牙技术,使系统更加的方便和实用。更多还原

【Abstract】 With the development of science and technology, the request to the orientation technology is increasing,but when the signal receiverd is from the satellite,and the receiver must be parked in the open air where there is not any tall building,which makes the use limited. So In this paper, a bluetooth based orientation system is designed,the bluetooth technology will be adopted here,combined with the mobile communication technology,as a result,relative orientation is realized.The topic of this paper roots in the plan task of great innovation of the nation. For the appereance and development of the bluetooth technology,instead of the cable,the cost’s decreasing caused by a great deal of production,the task based on the bluetooth technology is very practicable.This system is developed on the platform of embedded Linux operating system, the information is transformed by GSM network,the bluetooth technology is adopted,and the graphic user interface is designed by Microwindows and FLTK.This paper analyses the newest orientation technologies,and then chooses the 9553X made by the company of LEADTEK,and puts up a bluetooth GSM system by Q2406B made by the company of WAVECOM,by which the GPS information is shared,the OMAP1510 of TI is chosen as the platform of hardware of the embedded system.So we realized the decoding and display of GPS information,the estimation and display of the direction and speed,and the relative orientation system.The practices have showed that the relative orientation combined the GPS and GSM is feasible.At the same time,adopting the bluetooth technology makes the system more convenience and practicality.更多还原
