基于MSP430F149的车载蓝牙免提系统的设计与实现

Design and Implementation of Vehicle Hands-free Bluetooth System Based on MSP430F149

为改善传统车载免提系统的性能和用户体验,该文提出一种低功耗、高音质、多功能车载蓝牙免提系统的实现方案。该系统采用软硬件相结合的设计方法,基于MSP430F149和BC05进行研发。文中先简介该系统的组成,然后详述其工作原理及软硬件设计,最后给出黑盒测试与白盒测试相结合的方法下系统性能的分析。通过实测,该系统不但可以实现免提接听、挂断、声控拨号等功能,而且与传统车载免提系统相比,功耗低,音质好,具有良好的用户体验。

In order to improve the performance and user experience of traditional vehicle hands-free system, a new method about Vehicle hands-free Bluetooth System is put forward. The new system is low-Power, high fidelity and multifunctional. And the design of the new system was based on the design method of software and hardware combination, MSP430F149 and BC05 in general. First of all, the paper introduces composition of the system briefly. And then the system＇s operational principle and design of hardware and software are presented in detail. Last but not least, the system＇s performance is analyzed by the method of black box testing and white box testing combination. Experiments have proved that the new system can realize many functions, such as hands-free, hang up, voice activated dialing,etc. And comparing with the traditional vehicle hands-free system, the new onecan not only realize basic function as the traditional one, but also its sounds are clear and perfect. It has a good user experience.
