车辆监控系统的研究是集全球卫星定位系统(GPS)、地理信息系统(GAS)和无线通讯技术为一体产生的一个崭新的领域。论文首先提出了嵌入式车辆速度监控系统的总体设计思想和所用技术,然后阐述了系统的需求分析,系统使用嵌入式实验箱Cortex-A8的使用方法、Linux交叉编译软件环境。利用嵌入式实验箱Cortex-A8搭建嵌入式系统开发环境,搭建Boa服务器,利用Cgi编写网页程序,而后分别介绍了步进电机、LED矩阵、跑马灯、数码管以及蜂鸣器模块的功能设计,在此基础上给出了系统的实现方法,并对于各功能模块进行测试。
The research of vehicle monitoring system is a brand-new field produced by the combination of Global Positioning System (GPS), Geographic Information System (GAS) and wireless communication technology. Firstly, the thesis puts forward the overall design idea and technology of embedded vehicle speed monitoring system, and then elaborates the requirement analysis of the system. The system uses the Cortex-A8 embedded experiment box and the Linux cross-compile software environment. Cortex-A8 is used to build an embedded system development environment, a Boa server is built, a web page program is written by Cgi, and then the functional design of the stepper motor, the LED matrix, the marquee, the digital tube and the buzzer module are respectively introduced. On this basis, the system realization method is given, and the function modules are tested.
