Can Be Applied for Bluetooth Low Energy to i-construction? : Characterization of BLE on Excavator

Abstract

The Government of Japan has declared that construction sites must implement i-construction, in which information communication technology (ICT) is used to improve construction site productivity and throughput. Examples of iconstruction include remote and automatic control systems for construction machinery, for which wireless communication is generally required; however, the wireless characteristics that must be considered in i-construction remain unclear. To clarify these characteristics, Bluetooth Low Energy (BLE) beacon module is implemented for construction machines, and we investigate its communication characteristics. We focussed on two evaluations: characterisation of the BLE unit module and its feasibility in i-construction. Experimental results were used to characterise BLE communication in a residential area and construction site. In the latter, BLE beacon module communication was possible between a sender located in an excavator attachment and a receiver in its cabin.

Characterization of IEEE802.11 WLAN Implementing on Excavator: Can We Use IEEE802.11 for i-construction?

“…Future works include an evaluation of the performance when the construction machinery was working, and multiple devices were in the WLAN. Further, it needs to be evaluated in an environment where other radios using the 2.4-GHz band (such as Bluetooth using devices such as BLE beacon devices [29] exist) were present. Finally, applications of i-construction using the IEEE802.11 WLAN will be implemented.…”
