摘　　要：由于交通安全、拥堵等问题被广泛关注,设计了基于OBD和GPS的车载终端系统。系统从两个方面进行设计,一是基于OBD接口采集车辆在行驶过程中的实时数据,通过采用EST527-miniS车联网OBD模块设计采集电路与汽车的OBD系统进行连接,读取汽车在行驶时的实时运行参数,使车主能够通过本系统更加直观的了解车辆的实时参数,对车辆的车况有较为全面的了解,从而减少潜在的安全隐患。二是在获得本车信息的基础上,通过GPS模块实现车辆的准确定位,采用DSRC技术实现车辆之间多种信息的实时交互,确保车辆处于安全行车的状态。通过在真实车辆上搭载该系统,对整个终端设备的各部分功能进行测试,达到了预期目标。Due to the wide attention of traffic safety,congestion and other issues,it designs a vehicle terminal system based on OBD and GPS.System from two aspects to carry on the design,one is based on OBD interface to collect realtime data in the process of vehicles on the road,through the EST527-miniS OBD acquisition circuit module design and the automobile to connect OBD system,the real-time running parameters while reading cars on the road,the owner can through this system more intuitive understanding of the real-time parameters of vehicles,have a more comprehensive understanding to the vehicle cars,thus reducing the potential safety hazard.Second,on the basis of get information on the local,by GPS module to realize accurate positioning of the vehicle,DSRC technology was adopted to realize the vehicle real-time interaction between a variety of information,to ensure that the vehicle is in a state of safe driving.By carrying the system on the real vehicle,the function of the whole terminal equipment is tested and the target is achieved.
