【摘要】：北斗卫星导航系统是我国自主建设、独立运行的全球卫星导航系统,可为用户提供高精度、高可靠的定位、导航、授时服务。建设具有知识产权的北斗卫星导航系统,对于保障国家信息安全等方面,具有十分特殊的意义。本课题是研究开发一种基于嵌入式处理器与GPRS通信方式采集并发送目标定位数据,通过云服务器上的数据库接收,结合百度地图API技术的目标定位监测系统。本文主要是研究前端定位数据采集、处理与发送电路设计,为云服务器数据处理与定位提供数据传送服务。本课题设计的北斗卫星的定位终端包括数据接收模块、无线发送模块、定位数据显示模块和数据处理与控制模块。其中,数据处理与控制模块为基于ARM9处理器的S3C2410。首先将北斗卫星模块接收的目标位置数据通过串口传送到S3C2410模块,进行解析处理与封装,处理后的定位信息在本地显示,并将处理后的定位数据通过GPRS模块传送到上位机。控制模块部分针对基于嵌入式软硬件可以裁剪的特点设计了一个最小系统板,并对linux内核移植和U-bOOt移植以及根文件系统制作进行了分析。本系统经实际测试基本实现了预期功能,与云服务器上的上位机定位应用软件共同构成了基于北斗卫星的目标定位系统,定位精度较高,经完善后在定位应用方面有很大的实际意义。
[Abstract]:Beidou satellite navigation system is a global satellite navigation system which is independently built and operated independently in China. It can provide users with high precision and reliable positioning and navigation. The construction of Beidou satellite navigation system with intellectual property rights will ensure the national information security and so on. This project is based on embedded processor and GPRS communication mode to collect and send target location data, and receive through the database on the cloud server. Combined with Baidu map API technology of the target positioning monitoring system. This paper mainly studies the front-end positioning data acquisition, processing and transmission circuit design. The positioning terminal of Beidou satellite designed in this paper includes data receiving module and wireless sending module. Positioning data display module and data processing and control module. The data processing and control module is S3C2410based on ARM9 processor. Firstly, the target position data received by Beidou satellite module is transmitted to S3C2410 module through serial port. Parse processing and encapsulation, after processing the location information in the local display. And the processed positioning data is transmitted to the upper computer through GPRS module. The control module design a minimum system board based on the characteristics of embedded hardware and software can be clipped. The porting of linux kernel, U-bOOt transplantation and root file system are analyzed. The expected function of this system is basically realized by practical test. The target positioning system based on Beidou satellite is constructed together with the upper computer positioning application software on cloud server. The positioning accuracy is high, and it has great practical significance in positioning application after being perfected.
