- 21. IoT Benefits • Smartproducts take corrective action to prevent equipment failure and keep production running
- 22. o An injectionmolding machine monitors the viscosity of it’s pump motor oil and takes itself offline if the oil is dirty, emails management and automatically logs a trouble ticket with maintenance technicians
- 23. o A remotenatural gas separator phones home to tell operators its batteries are no longer charging and production will soon stop
- 24. IoT Benefits • Datais easily shared among peer groups for faster problem identification and resolution
- 25. o Doctors acrossthe world are able to treat patients more quickly and efficiently by providing telemedicine as opposed to on site doctor visits – More patients are able to obtain medical care o The CDC uses Big Data analysis of remote medical sensor data reported by hospitals to preemptively spot flu outbreaks – pattern recognition
- 26. IoT Benefits • Yourhome becomes “smart” and proactively solves problems for you
- 27. o Your refrigeratoremails you on your way home to remind you you’re out of milk o Your thermostat recognizes your smart phone has been off the Wi-Fi network for over an hour indicating you are likely not home, turns off your AC compressor and sends you a text message letting you know what corrective action it took. Taking that one step further, you email your thermostat back and tell it to turn the AC back on.
- 29. A New Paradigm • It’s no longer about how fast a business can react to events • IoT and Big Data can provide real-time insight into all aspects of a business’s operations • The future will be about anticipating events before they occur to achieve the largest competitive advantage
- 30. How do weget there? • There are some inherent challenges with IoT o How do we all speak the same language? o Bridging the gap between embedded systems languages such as C and web languages such as JavaScript • It’s not just about hardware, but hardware is important. Software design is key • Leverage existing technologies, standards and architectures – it’s all available today!
- 31. Hardware Considerations • Firstwe need to get the device on a network • Ethernet (MAC/PHY) or Wi-Fi connectivity (802.11 chipset) • TCP/IP stack • Enough processing power and RAM to handle security o Encryption/SSL o Authentication
- 32. Software Considerations • Datawill move on the internet of things via web protocols o API’s, ideally in a RESTful architecture, will be used to bridge different communication protocols and programming languages o API’s are the key to moving data from an embedded development platform using languages such as C to something the Internet of Things can understand and interact with • Designing your APIs could be as important as your hardware design!
- 33. REST API’s • Allowssoftware to talk to software • Stands for REpresentational State Transfer • Uses HTTP/s protocol, very similar to how the web works • Allows for reading and writing of data between disparate systems
- 39. A few noteson security • When mission critical systems start connecting to the internet, it’s imperative that they’re well secured • Encryption and Authentication should be a design requirement for all devices going forward • It’s easier to design security into a system from the beginning than it is to add security down the road
- 40. IoT Authentication • OAuth– Designed to solve the application to application security problem o Version 2.0 uses SSL to generate authentication tokens – Makes it easier to implement (not an IETF standard, yet; be prepared to change your code) o Version 1.0a has more available code libraries to choose from • API Key – Process to authenticate by exchanging keys • Username/Password – Least ideal, requires SSL
- 42. IoT Encryption • SSL– Secure Sockets Layer - Still the best • Almost all web applications use SSL for data encryption • When working on your hardware design be sure you choose a CPU and RAM that can handle the processing requirements of SSL
- 43. IoT in IndustrialAutomation • No standards yet o This is good and bad o Using an open architecture as opposed to a standard allows for faster development time and the ability to tailor implementations to specific applications while maintaining a common thread for general communication • The key to rapid adoption of IoT in industrial automation is the development and publishing of API’s from industrial automation equipment OEM’s
- 44. The Data Problem • Last year “things” surpassed humans for generating the most data on the internet • A “connected car” can generate 300 MB of data per second per car • We’re going to run out of bandwidth • The price of bandwidth and communication is not going down as fast as the price of storage and computing power
- 45. The Data Solution • Push intelligence to the network edge • Data mining performed at the sensor aggregation location can greatly reduce the amount of data sent to the cloud • Smart systems such as programmable automation controllers (PAC’s) can process data and report by exception as opposed to just dumping data on the network to be mined later
- 46. Opto 22 andIoT • At Opto 22 we’re on the forefront of implementing IoT technologies in our products • Core focus is RESTful architecture for our suite of industrial IO and mobile operator interface products • Imagine being able to use a web app and API to configure and control a pool of remote sensors or IO points
- 47. In conclusion • Designsystems for IoT from the perspective of a hardware developer and a software developer • RESTful architecture is at the core of IoT • Think about security at the beginning of your design • Utilize technologies that are already widely available (RESTful API’s, SSL, HTTP, TCP/IP, etc.)
