Problem Summary

Based on the idea of improving accuracy with Internet-of-Things (IoT) devices and improving efficiency with Blockchain, our aim is to integrate both to form a revolutionary solution to track the movement of aircraft engine repair parts through the workshop and record data captured in the overhaul process. This reduces transparency and mutability issues faced in the current ENVIS system.

SUTD-ST Engineering Aerospace: Blockchain and IoT for Product Tracking

Background

In the Maintenance, Repair and Operations (MRO) of aircrafts, services provided are safe, reliable and of high quality. Repair worksheets are created for each repair part. They contain instructions on the repairs, which are completed at different stations. The set of instructions carried out are then logged in the Engine Visual Info System (ENVIS). The aim of this project is to improve the ENVIS system.

Ultra-wideband Tracking Device (UWB)

Internet-of-Things (IoT) can be utilized for asset tracking, where it uses sensors and devices to monitor and manage an asset's position and movements. UWB is a high bandwidth radio-based technology used for the transmission of data.

 

To transmit the location of an item, four UWB devices are necessary, three anchors and one tag. The anchors are placed at fixed positions and the tag is attached to the tracked item. The radio waves from the anchors and tags determine the location of the item in real time. By querying, the locations are then stored in Firebase, a centralized server.

Ethereum Blockchain Decentralized Application

Blockchain is an immutable ledger that facilitates recording transactions and tracking assets in a network. Ethereum decentralized application (DApp) runs on a distributed network. It is highly transparent, secure and improves the efficiency of many industries.

 

Each stakeholder has a unique ID with Metamask. Once a repair is completed, they will stamp off with this ID and Ganache will confirm and record this action. It is immutable, allowing an accurate history of the work done on the parts.
