Community: UI Interest Group: Cool Tools for controlling the Front Panel (UI) Objects
Street lamps have always lit our way through the night, and now they are lighting the way to a greener planet and a brighter future. Scientists at Mir Energy Solutions developed a gateway that can remotely dim and shut off street lamps based on the time of day and local events while significantly reducing energy consumption and carbon dioxide emissions.
Mir Energy Solutions used NI LabVIEW Real-Time system design software to develop programming for the system, and the NI sbRIO 9601 to control and communicate to the lamps. This gateway system of communication reduces energy costs of the street lamps by 25 percent and maintenance costs by 40 percent and protects them from voltage fluctuation.
The engineers at Mir Energy Solutions were able to control about 200 street lamps through RF network and gather performance and cost savings data in graphical visualization form. This wireless monitoring and control system can even track failures and provide different reporting options back to the controller by combining a geographical information system with the web-based application.
This front panel template tool can be integrated into LabVIEW to allow you to select a VI in memory or browse to a VI on disk. You can also use this tool to change a VI’s front panel indicator and controls.

This example shows how understanding LabVIEW functions can reduce your frustrations when adapting text-based code to LabVIEW.
While most people take cover when a tornado strikes, meteorological scientists from TWISTEX chase after them to capture ground-level data to help researchers better understand and predict atmospheric conditions. So when it came time for TWISTEX to develop a sturdy, stand-alone instrument that could collect, store, and visualize large data sets, they turned to NI products and LabVIEW to help them out.
The TWISTEX team used NI CompactDAQ hardware, LabVIEW, NI DIAdem, and an NI 3110 industrial controller to obtain, process, and display the sound, temperature, air pressure, wind speed, and direction from the bottom 2 m of the tornado. Using NI products, TWISTEX created an instrument that can measure audio from inside a tornado funnel, a first for meteorological scientists everywhere.
