摘要
针对当前公交报站系统中存在的一些缺陷和不足,设计了基于全球卫星定位技术的新型公交智能报站系统.运用片上系统(SoC)的设计思想,采用可内嵌IP软核的FPGA芯片,以内嵌的Core8051软核作为系统微控制器,利用FPGA片上逻辑和存储资源设计系统外围模块.完成具备进出站播报,超速报警,转弯提示,当前时间、温度及速度的实时显示,线路切换等功能的报站系统设计.
This paper designs an intelligent bus-stop announcing system using GPS （ Global Positioning System） technique in terms of the defects and shortages of current bus-stop announcing system. By applying the design idea of SoC and using FPGA chip that is embedded with Core8051, the system achieves the functions of announcement of entering or leaving stops, over-speed alarm, turn prompt, display of the current time, temperature, speed, switch of routes and so on. The system is stable, reliable, multi-functioned, and highly accurate, and can meet the practical need.
