基于TOF/RSSI的公交车载节点组合定位算法研究

摘要

New wireless chip JN5148 which has TOF ranging function has been tested. Based on the-analysis of horizontal dilution of precision of mobile vehicle node, linear localization algorithm was designed, and a high-precision vehicle localization algorithm combining TOF/RSSI and odometer was put forward. Simulation results indicate that the combined vehicle localization algorithm has a wonderful effect, and it has good reference value for engineering application of perfecting the advanced public transportation system.%对具有TOF测距功能的新型无线传感器芯片JN5148的测距效果进行了分析测试,通过HDOP值分析了车载节点定位精度,制定了线性定位方案,并在此基础上提出了基于TOF/RSSI和里程仪的高精度公交车载节点定位算法.仿真结果表明,该组合定位算法具有良好的定位效果,对公交系统的智能化升级改造应用有参考价值.
