基于GPS的公交车智能报站系统设计

A Design of Intelligent Bus Stop System Based on GPS

设计了一种基于STC89C52单片机和GPS的智能公交报站系统。该报站系统无需关注车辆的行驶方向,将公交车往返线路上的全部站点信息以单向循环列表的方式存储在单片机中,并通过全局站点搜索进行公交站点的匹配计算。完成了系统硬件电路的设计和控制程序的编写,并制作了实物。经验证,该系统能实现全自动进出站预报和显示,并且在车辆发生掉头或跨站时也可实现精准的站点判定。

A designs of intelligent bus stop system based on STC89C52 MCU and GPS was made. Instead of focusing on the driving direction of vehicles, this system stored all the stop information on the STC89C52 MCU lining in a one-way circular, and performed matching calculation of the bus stops through a pattern of overall site search, then conducted system programmings in the hardware circuit and the controlling process. The real system was produced as well. It has been verified that the system could forecast and display all the stops automatically, and could also predict stop accurately when vehicles are turning round or missing stops.
