Auto-positioning of UWB RTLS for Construction Site Applications
Real Time Location System (RTLS) has been confirmed with high suitability for various construction site applications in the past decade: resources tracking and productivity monitoring, labor and equipment safety, as well as robotics navigation on construction sites. Studies have confirmed that TOF-based Ultra-wide Band (UWB) RTLS has higher practicality for construction site applications compared with the most commonly investigated TDOA/AOA. To setup a TDOA/AOA UWB RTLS, precise surveying (e.g. using Total Station) are required to determine the locations of the anchors and setup the coordinates of the system. Due to the dynamic nature of construction sites, it is inevitable to frequently move the anchors during the different stages of the construction which necessitates repeating the surveying and installation efforts. Nevertheless, it is not practical to keep repeating the survey processes throughout the entire construction. Auto-positioning, as a unique feature of TOF-based UWB RTLS, can automatically determine the relative locations of all anchors, which shows significant promise in simplifying the applications of UWB RTLS in the dynamic environment of the construction sites. Nonetheless, as a recently emerged new feature, the mechanism of auto-positioning is unknown and the impact of applying auto-positioning is still unclear. The objective of this study is to investigate the mechanism of auto-positioning of the TOF-based UWB RTLS and evaluate the influence of applying auto-positioning on location estimation accuracy. By thoroughly analyzing the mechanism and algorithms of auto-positioning, the influence on the location estimation accuracy will be associated with the mechanism of auto-positioning (245/250).
