• Abstract:
  The overarching goal of this project was to instrument the new MnDOT Navistar truck used at MN Road. A
  
  rugged data acquisition, data recording and wireless transmission system was established for collection of various
  
  sensor signals from the truck. The truck was instrumented with a suite of 20 accelerometers, with these
  
  accelerometers being located both on the five axles of the truck and on the tractor and trailer bodies. In addition,
  
  the truck was instrumented with a differential GPS system and an inertial measurement unit in the tractor cab. A
  
  cRIO-based data acquisition system, a rugged laptop and Labview software together serve as a flexible platform for
  
  data acquisition. A wireless communication system has been established to communicate trigger signals to
  
  roadside cabinets when the truck is at desired GPS locations on the road. Data recording by in-pavement sensors is
  
  triggered by this system. Software has also been set up for automatic downloading of data from the truck to a
  
  server on the network at MN Road. The experimental performance of the developed system has been verified by
  
  multiple tests conducted by the research team. The above instrumentation of the truck will enable data collection
  
  on truck vibrations, enable analysis of correlations between truck vibrations and variations in signals of weigh-inmotion
  
  sensors, and enable recording of truck movements and pavement loads at MnROAD.
