摘要
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。
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 trans- portation system.
