The Naval Surface Warfare Center has invented software tools for wireless power system designers. The patent-pending technology is available to qualified businesses for productization through a license agreement.
Far-field wireless power energy systems (WPES) promise to deliver electricity from a remote location to such items as drones, sensors, and maybe even, cars. Design of these systems mandates the inclusion of a wide variety of engineers usually working in a highly distributed environment. The individuals or teams working on these systems often use different design methodologies or have varying ways to compute different performance or efficiency predictions. This leads to the creation of unworkable designs that suffer from a range of engineering or system integration failures from inoperability in a given set of operational conditions to burn out or component failure.
A variety of reasons for these failures have been identified including design processes and systems that do not enable designers or engineers to effectively balance performance, design, operational needs, component limitations, and constraints in a way that supports cognitive function and understanding on the part of designers and users.
Addressing these issues for WPES design, Navy scientists have developed and pressed into use a robust distributed modeling, simulation, analysis, and visualization (MSAV) environment.
The software includes a design element input section to receive user-design specifications including element performance and constraints along with design element variables; a design-build section to enable users to select one or more of the design elements and create a system of design elements; and a variable control section that enables visual locking of one or more variables to enable modeling or simulation of dependent and independent variables.
As an indication of the utility of this design and analysis suite, one unique feature is the calculation of atmospheric efficiency of the propagating EM wave along a path between a transmitter and receiver. This feature uses built-in MATLAB functions such as gaspl, accessing and manipulating publically available databases, and formulas from the International Telecommunications Union. In addition, an atmospheric attenuation sub-GUI can be generated that displays the World map with various overlays that incorporate monthly average atmospheric conditions (air temperature, specific humidity, and water vapor density), the path between transmitter and receiver, and ultimately the specific attenuation for the desired region of interest.
- System enables visual comparison of different design variations
- The GUI is designed using modular classes to seamlessly add-in features or capabilities
