摘要
针对车辆的主动安全性需求,应用车-车通讯技术设计了一种无线定位系统.首先,根据车-车通讯的技术要求,确定采用ZigBee技术作为无线通信方式;其次,对无线定位系统的构成进行了设计,利用基于测距技术的定位算法和"距离-损耗"模型对网络的移动节点进行了定位;最后,利用标定的定位模型对该无线定位系统进行了实验验证.结果表明:该无线定位系统性能良好,能够满足车辆行驶条件下的定位要求,提高了车辆的主动安全性.
According to the vehicle safety characteristics, a wireless positioning system based on vehicle active safety was designed by car-to-car communication technology. As the technological demands of car-to-car communication, ZigBee technology was chosen to accomplish wireless communication. Both software and hardware as- pects of the system were designed. Moving node was located by position algorithm which is based on measure distance technology and ＂Distance-Loss＂ model. Using the marked model, wireless positioning system was verified, the result shows that the wireless positioning system based on vehicle active safety is of good quality and meets the positioning requirements of vehicles.
