摘要
汽车车载T-Box作为人与车、车与外界的通讯设备,可以实现拔打电话、收发短信、语音控制、语音播报等功能,增强了用户体验及服务。本文研究基于天通通信、北斗短报文通信、双频导航于一体的车载终端设备。在地面基站信号较弱的环境下,通过双频导航和陀螺仪计算汽车方位,可以实现天线自动指向卫星,进行天通数据流量通信和北斗短报文应急通信,达到较好的应急通信质量。同时详细描述了该一体化终端的设计思路。
As a communication device between people and vehicles,as well as between vehicles and the outside world,the car mounted T-Box can achieve functions such as making and receiving calls,sending and receiving short messages,voice control,and voice broadcasting,enhancing user experience and services.This article studies a vehicle terminal device based on Tiantong communication,Beidou short message communication,and dual frequency navigation.In environments with weak ground base station signals,using dual frequency navigation and gyroscopes to calculate the vehicle's orientation,the antenna can automatically point to the satellite for Tiantong data flow communication and Beidou short message emergency communication,achieving good emergency communication quality.At the same time,the design concept of the integrated terminal was described in detail.
