基于GPS的嵌入式公交自动报站系统的研究

针对国内公交系统报站装置应用的现状,提出了一个基于GPS定位的嵌入式公交自动报站系统。该装置采用嵌入式Linux操作系统及GPS卫星定位技术,利用站点经纬度信息作为触发条件,自动、准确地播报站名、服务用语,并提供广告等增值业务。具有触摸式人机交互界面,方便乘客查询相关信息。系统软件可通过串口升级,显示屏同步显示报站信息及广告,可同时存储多条线路,便于公交车临时更换运营线路,具有很好的应用前景。

The research of the embedded automatic station report system for bus based on GPS technology

In view of the present application situation of the domestic public transportation system, an automatic reporting station system for bus based on GPS technology is put in this paper. The embedded Linux operating system and the GPS technology are used in this system, and the latitude and longitude information of the stop is used as the trigger condition. It is capable of providing automatic and accurate announcement of bus stops, service information, and providing increment services such as the advertisement. It is convenient for passengers to inquire about information using human-computer interface on the touch screen. The software can be simply upgraded via serial port. The display provides real-time next stop information and advertisement concurrently. Multiple routes are stored so that change of service route temporarily can be made easily. It has the very good application prospect.
