在露天矿山环境中，采矿设备的体积通常非常巨大。因此，在高安装的驾驶舱内，设备操作员的视野受到严重限制，这些操作员往往不知道正在接近或附近的车辆。据报道，这种无意识导致了严重的事故，这促使我们对这些车辆进行近距离检测。车际通信（IVC）在道路运输环境中是一种很有前途的通信方式，但由于受巨大物体和地形影响，无线电传播的特性不同，因此不能直接适用于矿用车辆。本文提出了一种利用IVC支持露天矿驾驶员意识的方法。我们的想法是通过精确的光线追踪，为运输卡车建立一个无线电传播模型，这是露天矿山中最典型的车辆。在现场实验中，对实际无线电信号传播量进行了测量，并与模型进行了比较。然后，对采矿环境进行建模，并根据运输卡车的位置和天线的位置估计接收到的信号强度。指出了这种环境下的几个盲点，对露天矿V2V接近探测具有重要意义。
In surface mine environment, the size of mining equipment is typically very huge. Therefore, the sight of equip- ment operators in high- mounted cockpits is severely limited and those operators are often unaware of the approaching or nearby vehicles. It is reported that this unawareness causes serious accidents, which motivates us for proximity detection of those vehicles. Inter-Vehicle Communication (IVC) is a promising approach in the road transport environment, but is not directly applicable to mining vehicles due to different features of radio propagation affected by huge bodies and terrain. In this paper, we propose a method that leverages IVC to support drivers' awareness in surface mine. The idea is that we build a radio propagation model for haul trucks, which are the most typical vehicles in surface mine, by accurate ray-tracing. The model is validated in the field experiment, where actual radio signal propagation is measured and compared with the model. Then a mining environment, where steep cliffs due to excavation are often seen, is modeled and we estimate the received signal strength based on the locations of haul trucks and antenna locations. As a result, we point out several blind spots in such environment, which is significant for V2V proximity detection in surface mine.
