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.

Though NI LabVIEW is primarily used for engineering applications, its functions are capable of going far beyond just that of engineering. In fact, LabVIEW can be used to automate music composition.


Typically, composers and musicians are responsible for creating any background music they want to accompany an original melody. Composers usually analyze chords, signatures, and tempos to create the supplementing melodies. Recently, composers at Ngee Ann Polytech in Singapore wanted to find a new way to carry out this task. The composers needed a way to use technology as a source to generate music composition rather than just a tool.


By using LabVIEW software, the composers designed a system that first processes input from the keyboard or microphone. Then as the music is being processed, additional music components are generated and tempo and structure of the melody is set. The system reintegrates the elements with the user’s original melody and music notes and rules are formed.


The system design created two modes for processing the music, Automation Mode and Instantaneous Musical Automation mode. Automation Mode lets users input melodies on the piano key system. The melodies are then analyzed and background music is composed. To finish, a wav player reads the data and actually generates sound outputs in the wav format.

The Instantaneous Musical Automation mode is more ideal for suggestive composition and even karaoke. This mode essentially acts as robot pianist. As it detects vocals, the robot pianist creates the background accompaniment.


The success of the automated music composition system demonstrates the versatility of LabVIEW as well as its ease of use. LabVIEW software helped the composers create a system that processes sounds, creates complimentary melodies, and collects results. As technology expands in the music industry, composers are Ngee Ann Polytech will be able to build and expand on the automated music system they have created with LabVIEW.
