dc.description.abstract |
An attemptwas made to generate the required voltage in asphalt pavement
to operate roadway sensors utilizing a temperature difference between two thermoelectric
generators (TEGs). To enable output voltage by the TEGs below the asphalt
surface layer, the harvester was installed with the copper plate 25 mm (1 in.) below
the top surface layer. The copper plate is heated from the sun’s rays penetrating
the asphalt surface layer and transferring the energy into the harvester system. The
power generated from the TEGs allows temperature difference readings, as well as
maximum power output voltage. Optimizing the harvester for efficiency and sustainability
were top priorities. Once the copper plate receives the required voltage from
the heat generation, the Arduino can be turned on. To communicate with the Arduino
board in the current set-up, a USB cord gets plugged into the Arduino with the other
end into the computer. The software program Arduino should then be opened on the
computer to read data from the apparatus. An SD card or Bluetooth receiver was
implemented into the solar harvester unit. This allows data for retrieval to be stored
without an external power source (i.e., computer), allowing the harvester to operate
freely. The strain transducer was installed into the asphalt surface layer for strain
monitoring of the roadway. The SD card/USB would be able to store the information
from the pavement strain transducer. Data retrieval would be achieved simply by
unplugging the card from the harvester unit and uploading it to a computer. |
