Experimental Investigation of Chirp Spread Spectrum-based Swarm Sensors for Construction Resource Tracking

摘要

Emerging wireless sensing technologies hold great promise for improving construction resource tracking operations. Unfortunately, the accuracy and reliability of these sensing technologies as well as their interactions with the dynamics of the construction environment is still not well understood. Existing deployments of these sensing technologies are based on isolated tracking applications rather than adaptive interaction with the construction process. This adaptive interaction can be enhanced using Chirp Spread Spectrum-based swarm sensing systems capable of triggering collective and organized behavior amongst construction resources: a key characteristic of cyber-physical systems. This paper presents an experimental investigation of the performance of a commercially available swarm sensing system on the construction site. This sensing system consists of sensors capable of interacting and communicating with each other without the need for stationary transceivers. A case study is presented to demonstrate the benefits and functionality of the sensing system. The results show that Chirp Spread Spectrum-based swarm sensing systems offer tremendous opportunity for future cyber-physical systems applications in the construction industry.
