Indoor environmental quality (IEQ) monitoring is an important basis of smart buildings to ensure human comfort and control energy systems. IEQ monitoring conventionally relies on a limited number of stationary sensors deployed at selected locations, which has little capacity to capture fine spatial characteristics due to the cost of infrastructure and maintenance. This paper describes a robot-based mobile sensing system for high-resolution temperature monitoring by selecting air temperature as the targeted IEQ parameter. Experiments were conducted in a classroom to test the mobile sensing performance through comparisons with the dense stationary sensor network. Furthermore, two spatio-temporal processing methods were developed to reconstruct continuous thermal maps from short- and long-term monitoring. The results indicate that the robot velocity of 0.25–0.45 m/s is better than 0.60–0.80 m/s and 0.10–0.20 m/s, and that the proposed methods are suitable for generating accurate, high-resolution thermal maps.

基于机器人的高分辨率室内温度监测移动传感系统

室内环境质量(IEQ)监测是智能建筑保障人体舒适度和控制能源系统的重要基础。IEQ 监控传统上依赖于部署在选定位置的有限数量的固定传感器,由于基础设施和维护成本,这些传感器几乎没有能力捕捉精细的空间特征。本文描述了一种基于机器人的移动传感系统,通过选择空气温度作为目标 IEQ 参数来进行高分辨率温度监测。在教室中进行了实验,通过与密集固定传感器网络的比较来测试移动传感性能。此外,还开发了两种时空处理方法,从短期和长期监测中重建连续热图。
