摘　　要：目前公交车上采用的公交报站系统具有语音和显示报站的基本功能,但由于报站时采用司机手动切换,一方面增加了司机的劳动强度,另一方面由于司机的错误操作,容易造成乘客误下或漏下,对公交运行带来很多不便。本文以GPS实现公交车行车路线的自动定位为任务,通过单片机C8051F320获取GPS定位的地理坐标信息,并对获得的数据作处理,自动判别当前行车的站点位置信息,当达到一定范围要求时进行相应站点的自动语音播报,同时显示当前站点的信息。该系统结构简易,实现了公交车报站的智能化,具有良好的应用前景。The Bus Stop Announcement system has two basic function： voice and display announcement, however, announcement of bus stop relied on manual operation of bus driver which could increase drivers＇ work and a lot inconvenient of traffic for mistaking take off when drivers＇ faulty operation. This essay discusscd how to use single chip C8051F320 to get information of geographic location from GPS and to process these attained data then distinguish thc positional information, when reach to a certain scope, the announcement can be made by voice of the bus stop information. This system is a simple and intelligent Bus Stop Announcement system which has a good application prospect.
