摘要 随着人民生活水平的提高,机动车数量日渐增长,然而道路是有限的,因此需要一个智能化的车辆协作车载系统来改善当前的交通安全问题。车载协作系统采用基于VANET(vehicular ad hoc networks)的网络特点的物联网技术作为信息交流的桥梁,这能够使车辆之间构建开放式ad hoc网络,进而有效降低远光灯阻碍视线、车辆内部安全问题等因非自身因素而引发的交通事故概率。该系统集合了GPS、nRF24L射频、紧急指示牌、车内环境监测等模块,实现车辆间的无线通信、指示牌提醒周围车辆、车内环境实时监测等功能。这些功能为交通行驶带来新的用户体验,从而优化当前交通现状。实验结果表明,车载协作系统能有效解决车辆间的通信以及车辆内部安全等问题。 With the improvement of people's living standard,the number of motor vehicle is growing but the road is limited,so an intelligent vehicle collaborative system is beneficial to improve the current traffic safety. The vehicle collaboration system uses the Internet-based networking technology of VANET( vehicular ad hoc networks) as a bridge of information exchange,which can build open ad hoc network between vehicles and thus reduce the probability of traffic accidents caused by obstruction of the high beam or the internal safety of the vehicle.The system combines GPS,nRF24 L radio frequency,emergency signs,vehicle interior monitoring and other modules to achieve the wireless communication between vehicles,signs to remind the surrounding vehicles,real-time monitoring of the environment and other functions.These features provide a newuser experience for traffic to optimize the current traffic situation.The experiment shows that the system can effectively solve the problems of communication between vehicles and the internal safety of vehicles.
