Sensing is vital Innovative sensing technology
IoT Benefits • Smart products take corrective action to prevent
equipment failure and keep production running
o An injection molding 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
o A remote natural gas separator phones home to tell operators its batteries are no longer charging and production will soon stop
IoT Benefits • Data is easily shared among peer groups for faster
problem identification and resolution
o Doctors across the 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
IoT Benefits • Your home becomes “smart” and proactively solves
problems for you
o Your refrigerator emails 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.
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
How do we get 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!
Hardware Considerations • First we 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
Software Considerations • Data will 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!
REST API’s • Allows software 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
A few notes on 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
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
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
IoT in Industrial Automation • 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
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
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
Opto 22 and IoT • 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
In conclusion • Design systems 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.)
