基于GPRS短信息的GPS汽车定位与防盗系统的研究

Research of GPS vehicle positioning and theft-against system based on SMS of GPRS

随着人民生活水平的普遍提高,汽车逐渐进入家庭。但是每年汽车的偷、盗、抢案越来越多。在此背景之下,运用GPRS短信息技术和GPS全球定位技术,在嵌入式开发平台上将二者完美的结合在一起对汽车定位防盗系统进行了研究,实现了汽车导航和防盗功能的结合及3大通用模块的应用。系统研究的过程中采用了开销较小的IP和UDP协议来实现GPRS通信,采用了定位精度高、可靠性高的Jupiter021 GPS接收机来实现GPS定位。系统应用起来稳定可靠,具有较强的实用性。

With the universal improvement of people＇s living standard, the automobile walks into the family gradually. But the cases of stealing and robbery of automobile become more and more serious year by year. Under current background, automobile positioning theft_against system is reserached by using the technology of GPRS and GPS based on the embedded developement platform, the function of automobile navigation and theft_against is realized by the application of three general modules. In the process of the research, the less expensive IP and the UDP protocols are used to realize the GPRS communication; Jupiter021 GPS receiver with high accuracy and high reliability is used to realize GPS positioning. The system possesses some advantages such as stabilization, credibility and practicability.
