摘要
提出一种基于随机无线信号择优关联的灾区通信盲区车辆定位模型,分析无线传感网络发射功率对灾区通信盲区的影响,利用灰色系统原理分析灾区通信盲区中随机无线信号间的关联度,依据随机无线信号的关联度大小,排出灾区无线通信盲区信号的优劣次序,将最优的随机无线信号输入灾区车辆定位算法,采用优化的三边测量法获取待定位车辆的位置信息。实验结果说明,该种模型可以对灾区通信盲区的车辆进行准确定位,具有较高的定位效率和鲁棒性,达到了预期的定位要求。
Put forward a kind of wireless signal based on stochastic optimal associated disaster area communication blind zone vehicle positioning model, analysis of wireless sensor network transmission power to the disaster area communication blind area and the effect of using the grey system principle analysis of the disaster area communication blind zone in the wireless signal, the correlation between random based on random wireless signal correlation size, discharge the pros wireless communication signal blind area in the disaster areas, will be the most optimal random wireless signal input in the disaster areas the vehicle localization algorithm, the optimization of the trilateral measurement method is adopted for pending the location information of the vehicle. The result of the experiment shows that this model can be accurate to the disaster area communication blind area of the vehicle positioning, has high efficiency and robustness, has reached the expected requirement.
