城市公交车载GPS定位系统设计

In order to ensure management of urban bus in gear and induce the complex operation in travelling crane course, this paper will introduce a simple and effective GPS positioning system of urban bus controlled by single-chip computer. The vehicle uses GPS technology to obtain the information of itself position and sends it to AT89S51.AT89S51 processes data, estimates the station point, displays the station point information by LCD, and achieves to broadcast station point automatically. This paper discusses mostly the design of hardware circuit and software of the part carried on vehicle. This part mostly deals with gathering information, processing information and controlling vehicle interior.
