一种公交车自动报站器设计方案

基于导航技术在车载终端中的发展趋势,设计提出了一个基于GPS/BD2定位的公交自动报站器的设计方案。该报站器以NXP公司的LPC3250作为主控MCU,并配有GPS/BD2双模导航模块、GPRS、调度屏模块、SD卡。采用此报站器,驾驶员不需要手动报站,从而更加专心于驾驶,减少了安全隐患,并且实现了公交车自动语音报站、实时监控、车载多媒体播放等功能,能够很好的满足公交智能化的要求,适合在大中城市公交车中安装使用。

Design of Automatic Broadcast Bus Terminal Based on Navigation

In view of the developing trend of navigation in vehicle,an automatic broadcast terminal for buses based on GPS/BD2 dual-mode navigation is designed.The automatic broadcast terminal is mainly composed of LPC3250,GPS/BD2 module,GPRS,SD card and schedule screen.As the terminal is used instead of manual broadcast,bus drivers can pay more attention to driving to prevent the safety problems,and it implements the function such as declaring station automatically,real-time adjusting route and playing multimedia.As meeting the requirement of intelligent buses,it can be applied to the buses in the large cities.
