中文摘要:
      为了克服隐蔽工程、大型商场、地下矿井与内停车场等复杂环境难于采用GPS实现自身的精确定位,探讨了一种采用智能手机基于RSSI测距的三边定位算法实现。指出了GPS室内定位面临的挑战,分析了三边定位算法的优势,讨论了基于RSSI测距的原理,研究了基于智能手机的定位算法实现。搭建了操作平台,在集成开发环境下开发了一个实验测距系统,实际测试数据验证了该实现方法的合理与可行性。实验结果与分析表明:所开发的定位系统可满足某些特定的室内定位要求。
英文摘要:
      In order to overcome the puzzle of being difficult to use GPS to accurately locate oneself in hidden engineering, large shopping malls, underground mines and inner parking lots and other complex environments, this paper explored a sort of indoor trilateration algorithm implementation based on positioning of RSSI using a smart phone. In the paper, it pointed out the challenges of GPS positioning, analyzed the advantages of trilateration algorithm, discussed the principle based on RSSI positioning, and studied on the implementation of positioning algorithm based on smart phone. It built the operation platform and developed an experimental positioning system under the integrated development environment, and the actual test data demonstrated its rationality and feasibility. Experimental results and analysis show that the developed positioning system could meet the some requirements for indoor positioning.
