基于无线射频的公交预报站系统

Transit forecast system based on RF technology

公交预报站系统是城市智能交通系统的重要组成部分,可以有效地优化公交调度、提高市民乘车效率。本文设计了基于无线射频技术和STC12C5A单片机的公交预报站系统,可以代替常用的基于GPS技术的公交预报站系统。系统通过无线射频技术,以接力方式将公交到站信息传输到下行站点,并在站点通过语音和LED显示两种方式对即将到站的公交车信息进行预报,方便市民选择合适的公交乘车方式。本文主要介绍了系统的组成和硬件设计。

Transit forecast system is an important part of Urban Intelligent Public Transportation System.It can effectively optimize public transportation and improve the efficiency of people traveling. bus forecast station system based on radio frequency technology and STC12C5A microcontroller is designed in this paper,which can replace the common bus forecast station system based on GPS technology. The system relays the bus departure and arrival information transmitted to the downstream site through radio frequency technology. voice and LED display on the site are two ways to predict the arriving bus information to facilitate the public to select the appropriate bus ride . This paper mainly describes the composition of the system and hardware design.
