基于智能灯具的辅助生活室内实时的定位
Intelligent Luminaire based Real-time Indoor Positioning for Assisted Living
摘要：
本文提出了一种实验评估的准确性，室内定位。这项研究是作为欧洲联盟项目的一部分进行的，该项目旨在为老年人护理创造信通技术解决方案。目前的期望是，技术的进步将补充老年人护理所需的人力，提高他们的生活质量，减少医疗保健支出。所提出的方法以可配置的网络物理系统的形式实现，该系统能够对居住在家中或住宅楼中的老年人进行室内定位和监控。硬件由定制开发的灯具组成，具有传感、通信和处理能力。它们取代了现有的照明基础设施，不会看起来不合适，并且具有成本效益。照明器记录由被监测用户配备的可穿戴设备发射的蓝牙信号的强度。该系统的软件服务器使用三边测量来基于已知的灯具放置和记录的信号强度计算人的位置。然而，由墙壁、家具和其他物体的存在引起的多径衰落引入了定位误差。我们以前的实验表明，房间级的准确性，可以实现使用基于软件的过滤一个固定的主题。我们目前的目标是评估系统的准确性，在一个移动的主题的背景下，并确定是否房间级定位是可行的实时的。
英文摘要：
This paper presents an experimental evaluation on the accuracy of indoor localisation. The research was carried out as part of a European Union project targeting the creation of ICT solutions for older adult care. Current expectation is that advances in technology will supplement the human workforce required for older adult care, improve their quality of life and decrease healthcare expenditure. The proposed approach is implemented in the form of a configurable cyber-physical system that enables indoor localization and monitoring of older adults living at home or in residential buildings. Hardware consists of custom developed luminaires with sensing, communication and processing capabilities. They replace the existing lighting infrastructure, do not look out of place and are cost effective. The luminaires record the strength of a Bluetooth signal emitted by a wearable device equipped by the monitored user. The system's software server uses trilateration to calculate the person's location based on known luminaire placement and recorded signal strengths. However, multipath fading caused by the presence of walls, furniture and other objects introduces localisation errors. Our previous experiments showed that room-level accuracy can be achieved using software-based filtering for a stationary subject. Our current objective is to assess system accuracy in the context of a moving subject, and ascertain whether room-level localization is feasible in real time.
