Robot-based mobile sensing system for high-resolution indoor temperature monitoring
Automation in Construction(2022)
摘要
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.
