摘要
针对目前车载蓝牙免提系统不能播报人名和播放短消息内容,致使驾驶员必须操作手机所导致的行车安全问题,设计了具有语音合成功能的车载蓝牙免提方案。该方案采用了XF-S3011语音合成芯片、GOC-MD-102蓝牙模块和LPC2138ARM7主控芯片,为降低系统功耗进行了专门设计,并嵌入了μC/OSII操作系统。结果表明,该系统不仅实现了播报人名和播放短消息内容的功能,而且运行稳定可靠,功耗低。
The bluetooth hands-free car kit scheme design with TTS function is discussed, in order to solve the driving security problem that the car drivers have to operate mobile telephone since hands-free ear kit can not broadcast name and SMS （Short Messaging Service） currently. Based on XF-S3011 TTS chip, GOC-MD-102 bluetooth module and LPC2138 microeontroller embedded the μC/OS II operating system, the scheme design is expatiated to abase the power consumption of system adequately. The results not only show that the proposed system can broadcast name and SMS currently, but also demonstrate its reliable stability and low power consumption.
