Indoor location and intelligent control system can bring convenience to people’s daily life. In this paper, an indoor control system is designed to achieve equipment remote control by using low-energy Bluetooth (BLE) beacon and Internet of Things (IoT) technology. The proposed system consists of five parts: web server, home gateway, smart terminal, smartphone app and BLE beacons. In the web server, fingerprint matching based on RSSI stochastic characteristic and posture recognition model based on geomagnetic sensing are used to establish a more efficient equipment control system, combined with Pedestrian Dead Reckoning (PDR) technology to improve the accuracy of location. A personalized menu of remote “one-click” control is finally offered to users in a smartphone app. This smart home control system has been implemented by hardware, and precision and stability tests have been conducted, which proved the practicability and good user experience of this solution.
室内定位与智能控制系统可为人们的日常生活带来便利。本文设计了一种室内控制系统,通过使用低能耗蓝牙(BLE)信标和物联网(IoT)技术实现设备远程控制。该系统由五个部分组成:Web 服务器、家庭网关、智能终端、智能手机应用程序和 BLE 信标。在 Web 服务器中,基于 RSSI 随机特征的指纹匹配和基于地磁感应的姿势识别模型被用来建立一个更高效的设备控制系统,并结合行人航位推算(PDR)技术提高定位精度。最终,智能手机应用程序为用户提供了个性化的远程“一键式”控制菜单。该智能家居控制系统已经通过硬件实现,并进行了精度和稳定性测试,证明了该解决方案的实用性和良好的用户体验。
