Day 1 final slide

Editor's Notes

• #15: Voice:Welcome Mr Victor MieresHi everyone, welcome again to this student day. I am happy to be here today to talk to you today about how students just like yourselves here in India and around the world are doing engineering with National Instruments tools. Jayaram talked to you about the importance of doing experimentation, doing engineering during your time in school. Now I want to talk to you about how to get this done and the approach the industry is adopting for designing, prototyping and testing the next products and systems.
• #16: One of the most prolific inventor of our all times was Thomas Edison, he developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. He did all of his experiments in this lab. This is a picture of his lab in Menlo Park. This is where he grabbed different elements, devices, component to build his experiments. What are the modern tools of engineering? To answer this question we must start with the essential elements of engineering.
• #17: The 6 key elements that engineers and scientists need to design and build the systems you see today in the industry include:First the math and analysis. Every system will use some sort of math function or algorithm and more and more the math needs to run in ever more distributed, smaller and embedded devices so having the ability to easily deploy or run those algorithms in different platforms will continue to grow. The models of computation are things like G code, dataflow programming, simulation diagrams, MathScript, etc. Reality is that software defines the functionality of most devices and systems today so the tools of programming are critical. Is also true that the increasing complexity of these devices tied with the pressure to reduce development time make it necessary for engineers to have the ability to integrate different types of tools of programming in one system.Another important element is the inputs and outputs to measure and control. These are the means by which we acquire data from the real world and control by generating output signals. From a simple digital on/off output to generate alarm to measuring a high frequency RF signal. I/O is always involved in the systems engineers build today.The user interface has to be an element within your system. People, operators, other engineers, etc. have to interact with the system, so you have to be able to have the user interface as part of this. Now, if you think about it projects you develop in the industry will be done in one platform, say a desktop for example but most likely the systems have to run in a different platform, that might be a Real-Time OS or an industrial PC but other deployable targets in the industry depend on the applications and can include things like FPGAs, things like multicore processors, things like Netbooks, for instance. Finally all of these technologies and any new versions must seamlessly integrate in your system. Reality is that commercial technologies change quickly and many times can bring benefits of higher performance at lower costs, things like new OS like Windows 7 or higher density FPGAs should be available for engineering systems at minimum effort. In other cases is just simply necessary for your system to integrate with other systems like legacy installations or new wireless communications protocols like wi-fi, bluetoothor others. These are the elements to build a science or engineering system, and you need to learn how to put them together to solve the problems in your job or to build a solution to one of those challenges. Now imagine having to program or code all of these elements for a final year class project and you have just a few months to finish it.
• #18: What we have done in NI istake those elements of the science and engineering system, and first of all, guarantee that they are compatible, that because they’re living in the same environment, they’re all going to work together. If I acquire the data, I know it’s going to be able to live in the same system that the analysis does. I know that I can abstract it out to some different targets. I know that I can go and get the user interface a connected.
• #19: And then, the information that each one of those brings in, I want to be sure that I can connect them together, guaranteed. If I string from here to here, I want to know and ensure, I will take it for granted, that this library talks to that library, and that’s a guarantee.
• #20: This is the essence of LabVIEW. How many of you have seen LabVIEW before? If you haven’t during the day today we will have workshops and hands-on sessions so you can see these elements in action.In our minds, from the perspective of the laboratory and bringing all these elements of science and engineering together, is the modern day Edison’s lab.But what are the types of things that you as a student can do with these elements?
• #21: To show us the platforms and applications possible please help me welcome to the stage Anish,Kanchan and Sagar from our NI India office.
• #22: Anish: Victor another platform recently released for measurements, instrumentation and control is myDAQ. NImyDAQ is like a student’s personal lab. It has two analog inputs, two analog outputs at 200 kS per second, 8 digital lines, and a counter. With a single device you have access to your own function generator, oscilloscope, or digital multimeter. This product is really going to revolutionize the access to measurements lab for students since now they have a portable and affordable set of instruments that can fit in their pocket. The types of projects you can design as a student are almost infinite but to show us just one I will ask Kanchar to explain her demo.
• #23: Thank you guys. Is interesting that last demo Kanchar showed you and the concepts you just saw in this demo like load measurements, solar panels monitoring and control of two energy sources are exactly in essence the concepts behind the smart grid problem that researchers and companies around the world are working on today. In fact we are working with companies here in India developing and deploying real-time smart grid system to help utility companies monitor and control the energy supply. Here is a real case study of how industry is applying these concepts and it’s impact in the local population.
• #24: In response to the lack of a cold chain infrastructure in India to transport fresh foods, Promethean Power Systems recently developed a refrigeration system to meet the unique set of challenges facing the Indian dairy industry. India draws its milk supply from millions of small farmers in villages scattered across the vast countryside. The current milk collection process is inefficient. It relies on twice-a-day pick up of warm milk, which results in high transportation costs and frequent spoilage – as much as 30 percent in the hot season. If dairies can immediately cool the raw milk at the village collection centers, they can cut transportation costs in half, save milk from spoiling, and pay their farmers more. Specialized milk refrigerators already exist, but the unreliable grid electricity supply means they must be operated with diesel-powered generators, an undesirable solution that increases capital and operating cost.Using these findings, Promethean designed a milk refrigeration system that is better suited for remote, rural areas. They based their design on solar power as a viable and economical power source in sunny locations such as India. However, because a milk cooling system is a mission-critical application that must run 24 hours per day, 365 days per year, we combined solar power with the available grid power to arrive at a superior system that can operate even during extended periods of cloud coverage or grid unavailability.A key component of our design is the control system that manages the power distribution from the two sources of power, solar and grid, to the loads. The loads consist of a refrigeration compressor that converts the electrical power to cooling power and stores the energy as thermal energy, basically a cold water tank. This cold water is later used to cool the milk during the morning and evening collection times. There is also a small battery system load that keeps the control system and pumps running when solar power or grid power may not be available.
• #25: LabVIEW is the environment where these experiments are happening and turning into functional prototypes, into real world systems, into the potential solutions that the local industry needs. With efficiency, making sure the I/O works with the user interface, works with the analysis libraries, and whatever model of computation you choose to use can be incorporated inside this graphical laboratory to build the science and engineering systems that use measurement and control. So really, LabVIEW becomes the system design environment for you to go and build the things that you want to do in the timeframes that you have.
• #26: The approach we have just described to design systems where those 6 elements are present and can be easily integrated through LabVIEW we call graphical system design. Today through the sessions you will see the capabilities of LabVIEW and the many possible hardware targets that can make possible the design of various types of systems, from RF and communications to robots.
• #27: Who uses Graphical System Design? NI India has been around for 14 years. Through all these years engineers in hundreds of companies and various industries have found benefits of using this GSD approach. When using GSD you will be joining aLabVIEW community of approximately 20,000students across India from over 1000 institutions. Once graduated and out in the industry, companies from the aerospace, automotive and energy industries are just a few of the NI customers.
• #28: Finally, to ensure NI technologies are accessible to all engineers, students and entrepreneurs in India we have a program called Planet NI.Through several initiatives both for academia and entrepreneurs we are working to ensure we can overcome obstacles like cost, training, sustainability and accessibility.
• #29: So experimentation as part of your forming years as an engineer is not only important but critical. But why are they important? Well because humanity is looking up to the engineering community to solve critical problems; from renewable energy and intelligent infrastructure to basic needs like high yield and sustainable agriculture to ensure food for all in this planet. Hopefully with the tools and these challenges you can find the inspiration needed to deliver on the promise of engineering. We are counting on you. Thank you
