摘要
设计了一种利用超宽带(UWB)技术的室内移动目标定位系统。通过在室内特定位置安装的基站和移动目标携带的标签,由改进的标准到达时间差(TDOA)定位算法,得到移动目标的实时位置信息,完成对室内移动目标的准确定位。采用Qt开发了一款上位机应用软件,可实时显示定位目标的位置及移动轨迹。最后搭建实验测试平台,对系统进行测试,将得到的位置信息与实际数据进行比对,结果表明系统整体通信稳定,满足定位需求。
An indoor moving target positioning system using UWB(Ultra-wideband)technology was designed.Through the base station installed in a specific location in the room and the tag carried by the mobile object,the improved standard TDOA(Time Difference of Arrival)positioning algorithm obtains the real-time location information of the moving target and completes the accurate positioning of the indoor moving target.Qt was used to develop a PC application software that can display the position and movement trajectory of the positioning target in real time.Finally,an experimental test platform was set up to test the system and the obtained location information was compared with the actual data.The result shows that the overall system communication is stable and meets the positioning requirements.
