摘要
针对小区域范围内的移动目标精确定位需求,设计了一种基于物联网的动态目标定位系统,采用CC2431集成的RSSI定位引擎为核心的ZigBee定位技术,相比全球定位系统(GPS)、北斗定位系统、超声波等定位技术可以满足室内对移动目标的实际定位精度要求。经过该系统对区域动态目标进行多次的定位测试以及仿真,实验结果表明,该系统对室内移动目标的定位精度达到0.20m^0.40m,是一种低成本、低功耗、高精度的定位系统。
Aim at accurate location of moving targets in the small area,this paper presents the design based on a IOT dynamic positioning system. ZigBee positioning technology using RSSI engine CC2431 integration as the core,compared to the global positioning system（ GPS）,Beidou positioning system,ultrasonic positioning technology can meet the actual positioning accuracy of indoor moving target requirements. After the system was repeatedly positioning test and the simulation of dynamic target,experimental results show that the localization of indoor mobile targets,the accuracy of the system achieves 0. 20 m to 0. 40 m, is a positioning system with low cost, low power consumption, high precision.
