    摘要:

    针对复杂地下道路环境内缺乏有效交通引导、定位导航的问题,分析探讨了现有室内定位技术的不足,研究了适用于普通手机终端的地下车行定位与导航系统。通过开发适用于复杂地下环境的射频矩阵基站、定位与导航引擎,结合普通智能手机终端,实现了具有低延时、高精度和高可靠性的地下车行导航解决方案。同时,于苏州中心开展了地下定位导航示范应用测试,结果表明:该系统能满足车辆在地下环境的定位与导航需求,实现与手机导航app对接,为驾驶人提供地上地下无缝衔接、稳定高效的一体化导航服务。

    Abstract:

    Aiming at the problem of the lack of effective traffic guidance and navigation in the complex underground road environment, the shortcomings of the existing indoor positioning technologies were analyzed and discussed. The underground vehicle positioning and navigation system suitable for ordinary mobile phone was studied. Through the study of radio frequency matrix base stations, positioning and navigation engines suitable for complex underground environments, combined with ordinary smart phone, an underground vehicle navigation solution with low latency, high accuracy and high reliability has been realized. At the same time, a demonstration application of underground positioning and navigation was carried out at the Suzhou center. The results showed that the system can meet the positioning and navigation needs of vehicles in the underground environment, with common mobile navigation apps, and provide drivers with a seamless, stable and efficient connection between the ground and the underground.
