蓝牙技术在车辆导航系统中的应用研究

Study of Urban Vehicle Navigation System Based on Bluetooth

本文主要讨论了把蓝牙技术应用到汽车上,和车载导航系统进行短距离无线GSM通信技术,提出了车载导航系统、路标传感器、控制中心的具体实现方法,对各部分硬件组成、软件的实现及其实现的功能进行了较为详细的叙述,重点介绍了蓝牙模块的硬件组成,给出了利用蓝牙通用模块进行无线数据传输的过程,同时介绍了它的实现方法。最后通过实验证明,把蓝牙技术应用到车辆导航系统中系统的精度大大提高,并且满足了一般用户的要求,具有广阔的发展空间。

This paper deals with the wireless communication between the Vehicle and the Beacon.The transmission of navig ation data is realized by bluetooth module,which is a short-range module.It introduces the usag e process of the bluetooth module.What's more,it analyzes how to prog ram to realize the transmission function.It introduces the three parts of Vehicle Navig ation System,which include their hardware,software and function.Fi-nally,the experimental result demonstrates the position accuracy the Bluetooth is applied to Vehicle Navig ation System,and satisifyg eneral user.Bluetooth has a vast developing space.
