Going Green, One Bus Stop at a Time

Tuesday, November 22, 2011

Two important elements in a sustainable urban infrastructure are public transportation and green structures. Not only are they important, but they also help create sustainable living conditions for a

community. That’s why engineers at National University of Singapore created the first working prototype of a zero-energy bus stop (node) that was also user friendly for commuters.

 

Powering a zero-energy bus node that is self-sustainable requires electricity. The engineers needed to situate solar panels on the top of the bus node. To further the energy supply, they mounted the solar panels on a rotational base that causes the panels to adjust with the weather information received by a controller. Using the energy supply from the abundant sunlight created enough to power one entire bus node.

 

The next crucial element was creating a solar panel powered system. The engineers created a three-part system made up of sensors, actuators, and a controller. They used NI CompactRIO hardware and LabVIEW software to give the controller capabilities for obtaining up-to-date arrival times, current traffic conditions, and other navigation information for passengers right on-site.

The use of integrated NI hardware and software helped engineers create the first working prototype of a zero-energy bus node. This entire bus node is 100 percent self-sustainable in electricity consumption and Singapore now has a ready platform for energy control activities that will help create a more sustainable infrastructure in the future.
