物联网通常用于研究分析和估计人类行为并通过移动的终端跟踪他们的确切位置。特别是，通过使用物联网进行本地化对于监视老年人，搜索失踪儿童或检测危险事件非常有效。在本文中，我们提出了一种混合系统的定位，可用作一个准确的监测设备，定期使用，并作为一个定位设备，具有低功耗和长跨度的操作，用于紧急使用。通过切换到在蓝牙低功耗下运行的系统来实现低功耗。作为与实际机器的实验结果，我们提出的系统可以定位的终端位于5米的距离内的区域，100%的准确度。此外，它的正确位置可以识别的准确率为84.2%，通过使用指纹的方法。
The Internet of things is often used on researches analyzing and estimating human behavior and tracking their exact locations through mobile terminals. In particular, localization through the use of IoT is highly effective for watching over seniors, searching a missing child or detecting risky incidents. In this paper, we propose a hybrid system of localization that can be used as an accurate monitoring device for regular use and as a localization device with low power consumption and a long span operation for emergency use. The low power consumption is realized by switching to the system operated on Bluetooth Low Energy. As a result of experiments with actual machines, our proposed system could localize the area of a terminal located within 5 m distance with 100% accuracy. Moreover, its correct position can be identified with 84.2% accuracy by using the finger print method.
