一种高精度双模定位的智能公交报站系统

摘要

Nowadays existing bus stop announcement systems have deficiencies in single positioning mode,low accuracy and unstable data transmission.This paper focuses on a new smart bus stop announcement system combining with BDS and GPS Dulan-system Navigation module,wireless data transmission module and the CORS.The new announcement system guarantees the accurate positioning and stably real-time communication.Experiments showed that the system reached 1m accuracy and could realize lane-level navigation.%本文针对现有的公交报站终端大多存在定位模式单一、精度低和数据传输不稳定等不足，提出了采用 BDS／GPS双系统融合定位模块、无线数传模块与连续运行卫星定位服务综合系统相结合的改进型智能公交报站系统，保证了在高楼和林荫等遮挡环境下定位的准确性和通信的稳定性、实时性。测试结果表明，该系统的定位精度达到亚米级，可以实现车道级导航，具有较好的应用前景。
