基于WiFi组网的通用智能车载终端设计

摘要

为了解决车载终端在复杂环境下通用性较差的问题,采用4G移动网络、定位及智能传感器技术,将Cortex A7核心处理器及智能传感器等硬件设计成一个智能车载终端.智能车载终端由主机和外设组成,主机和外设之间通过WiFi无线接口连接,实现定位、多种信息采集及通信回传功能.实验结果表明,该智能车载终端解决了在复杂环境下通用性差的问题,具有灵活扩展的特点.%In order to solve the incompatible problem of the vehicle terminal in the complex environment,combining 4G mo-bile network and compass as well as intelligent peripherals,a general and intelligent vehicle terminal is designed by using a core processor Cortex A7 and the different intelligent sensors.The intelligent vehicle terminal consists of a mainframe and the corresponding peripherals which connect with each other by WiFi technology.The vehicle terminal can collect positioning information and receive returned information.Experimental results show that the intelligent vehicle terminal not only over-comes the incompatible problem in the complex environment,but also has the characteristics of flexible configuration.
