PhD topic – Smart axle transducer transmitter for freight wagon condition monitoring systems

Esteban Bernal

Research summary

Comprehensive condition monitoring of freight wagons remains an unsolved problem, mainly due to the severe environment and the lack of electric power and communication connections. The recent developments in devices for the Internet of Things opens the possibility that condition monitoring may be in reach. The PhD study will explore the latest innovations and combine technologies toward a new transducer approach and design.

Expected completion date

January 2021

Key achievements

  • Design of a novel sensor node for on-board condition monitoring of freight wagon components.
  • Dynamic and electronic validation using simulation.
  • Lodgement of a PCT application PCT/AU2020/050331 “System and Method for Monitoring a Plurality of Vehicle or Infrastructure Components” 3 April 2020.
