摘要
待定位物的三维坐标监测是室内定位的一个重要指标。文中采用射频技术作为测距时的内部同步设置,考虑到室内布局的复杂性,待定位点到各个已知参考节点的测距值的集中定位计算采用无线数据传输。通过应用射频芯片CC1101和ATmega48控制芯片组成的射频信号收发模块,实现了超声测距时的内部同步和无线数据传输,提高了定位的精度、增加系统灵活性,并适于特殊的场合。利用LabVIEW软件实现最终数据处理,使得设计直观、适应性更强。
The three-dimensions of loeator is an important indicator for the indoor positioning. This paper adopts radio frequency technology as ranging internal synchronization settings. Considering indoor layout complexity, wireless data transmission is used for centralized positioning calculations of distances between the locator and each reference point. Through the applications of RF signal transceiver module composed of radio frequency chip CCll01 and ATmega48 controller chip, the design realizes ultrasonic ranging internal synchronous and wireless data transmission, thus it improves the positioning accuracy, increases system flexibility and is suitable for special occasions. Simultaneously, us- ing LabVIEW software for the ultimate data processing, the design becomes intuitive and more adaptable.
