在本设计中讨论了GPS-OEM板的工作原理和通信协议,结合硬件特点提出了基于嵌入式系统的GPS数据采集系统的方案,给出了基于GPS-OEM板和单片机的数据采集系统的硬件设计方案和软件设计流程,实现对GPS全球定位系统的定位导航信息的接收。本设计系统体积小、功耗低、可运用于车辆的导航系统中,同时其设计思路对其他GPS-OEM板开发也具有很好的参考价值。
In this design, the working principle and communication protocol of GPS-OEM board are discussed. The scheme of GPS data acquisition system based on embedded system is proposed based on hardware characteristics. The hardware of data acquisition system based on GPS-OEM board and single chip microcomputer Design scheme and software design flow to realize the positioning and navigation information receiving of GPS global positioning system. The design system is small in size and low in power consumption, and can be used in the navigation system of the vehicle. Meanwhile, its design idea also has good reference value for the development of other GPS-OEM boards.
