IoT – The Way to Modern Industries

BY :     June 13, 2018

It’s a recurring fact that heavy industry relies on proven aging solutions and often disregards « new and hyped » technologies.  Over the past few years, IoT was considered promising in this field because it is relying on something, people that live in constrained environment know: hardware. Using this familiarity IoT entered industries by the R&D doors, and are now becoming a way to Smarter Factories.

IoT – The early days in the industry

Far from the ever connected and data acquisition paradigm, the first industrials application for IoT device was perceived for what the hardware was, small devices that fulfill small functions. Most industries built their solutions ages ago, and are very shy about “changing something that works”.  The thing is, these solutions for an important part, are outdated and expensive to maintain because the world surrounding it has evolved. What was the state of the art fifteen to ten years ago, is almost state of the history and technologies involves in these solutions are becoming obsolete. Furthermore, not so long-ago design where monolithic because everything was to be done in terms of data transfer between nodes, and even when it was not the case, a considerable amount of cable quickly came in the way.  As technologies go, engineers follow: The young engineers of the internet bubble generation have been reaching the hierarchical position to take decisions. The industry has been undergoing an inner IT revolution. The first impacts where on the software: it is easier to switch to old one if something goes wrong. New generations of products have been designed relying on the freshly proven software design and solution started to change. VME racks where throw in the benefit of computers (sometimes even, when the criticality of the information allowed, to the cloud). Legacy buses disappeared in the profit or more moderns one, in some case the treatment was delegated to a COTS that used TCP, and that was the start of it.  As soon as the wall of monolithic and heavily embedded solution fall, engineers saw the opportunity to move to a more distrusted and flexible world, IoT devices where entering (in many cases, by the R&D doors) the industry. Their ability to connect to almost anything and provide a small service was an easy backup to heavy solution becoming obsolete.

 

IoT Device, not IoT.

Well, the device where providing solutions. The unchallenged cost of the devices and all the provided surrounding software allowed for ground-breaking demonstration and sold the promise of cheaper and more easily maintainable solution for the industry needs. But where was the “I”? Having a part of a system replaced by a small device ensuring the same functional perimeter is one thing. Even in some case the connectivity assets of these device offering lots of opportunities where used (to name few among many: Wifi, BlueTooth, USB, Eth, and for many more integrated buses like I2C, SPI, UART …). But the target was a functional replacement, a one to one communication with no other goal than to replace the ever-existing wires, or software interface. That is where industries discovered the complexity of the distributed paradigm. The configuration of these devices was defined at system scale and not at company scale, moving the things that were relying on these solutions was about to become a configuration nightmare, because of the protocol conflicts (ad-hoc wifi, can buses, spi buses)

 

That’s where the “I” kicks in.

The proof of concept has lived long enough to demonstrate its gain, industries are now relying on their IT department to do what they do best: industrialize a solution.

The best practices from the IT department and software expert were added. IoT device soon became connected to the company’s network, thus reaching the DHCPs. The configuration of the IoT device was also provided like any other computer allowing for a more homogenous solution. Indeed, some compromise should be made. Some solutions became deprecated in the benefit of newer ones.

This step was the perfect occasion to tackle one of the major IoT trouble the cybersecurity. It’s a well-known fact that the cybersecurity is an ever-growing concern for most industries today. Generic IoT device tends to enable most of their communication medium with default parameters thus offering the various entry point to bad-intentioned people. The industrialization phase was the occasion to lead an analyze on all these opportunities and remove them one by one, through the generic configuration applied to the device.

In possession of device integrated into their network and fully secured, the time had arrived for a new world of opportunities for IoT based technologies.

What users want, engineers do.

The integration of these devices on a company network allowed for easy configuration and overview of the systems. Using all the strength of their process industries are now designing IoT solution for their needs. The needs that can be fulfilled with a myriad of devices in your walls are endless:

  • “Hey, why aren’t we using this IoT Board that emulate this equipment to monitor the temperature of the room?”
  • “Hey, wouldn’t it be possible to check the production machine utilization ratio by looking at the order the control board receives?”
  • “Guys, I had a tremendous idea, using the mesh RF network all our boards already have, we could easily identify their movement from one room to another by checking the mesh quitting, mesh entry information!”
  • “Would it be possible to store all the data produced by this kind of device and throw it into a predictive maintenance algorithm?”
  • “Would it be possible to use the data produced by all the device of this benches to build a general project follow up on my SmartPhone?”

Well centralism, again. That’s the way state of the art goes, the buzzword is to disrupt, we never actually do, we take a  turn on history wheel. The distributed paradigm is now recentralizing in more global solutions that allow for monitoring of everything from one point (even if this point is itself distributed in a cloud, or premise or not). Industries are investing in the opportunities to have large-scale information, easily visible and treatable by other modern technologies (BigData, Learning …) and are truly becoming IoT-Enabled.

About

Early passionate in IT and electronics Vivien starts on its brother PC at the age of 7 and discover the joy of MSDOS6. Time pass and its dedication to anything computer related brings him to build its first desktop computer by himself at the age of 11 and starts some basic programming in C. After much time playing with microprocessors and tennis, he follows what he had always loved, and enter an engineering school where he chose a specialization in Realtime Embedded System Architecture. Arianespace welcomes him for its first internship on Kourou’s site (CSG: Centre Spatial Guyanais) where he successfully automatizes the revalidation process of the lunch table by shrinking it from 3 weeks to 10 minutes. Coming back to France October 2011, he starts a mission as a subcontractor for Thales Airborne System - Brest to refactor all the Basic Software of the MELTEM & EAU Programs (Maritime surveillance). As the mermaids of the space industry still song in his hears he joins Thales Alenia Space in August 2012, were he works on real time test benches for the Iridium-Next program also as a sub-contractor. He is employed by Thales Alenia Space 10 month later as Test Benches Design Authority. The three following years will be dedicated to the complete redefinition and reconstruction of the Test Benches architecture based on Iridium REX. As big organization goes the department in which he works undergoes a reorganization and Vivien is sent to the Innovation – Research and Development department where he will work on different subject like test benches of the future, but mainly Realtime on board software subjects in collaboration with ESA and the CNES. Most of his time is dedicated on the edition of a project with the IRT (Institut de Recherche Technologique), and his sons. The project aims at providing a new on-board computer based on COTS processors. In the meantime, Vivien is project manager for both O3B-Block 3 EGSE (Electrical Ground System Equipment) project and MTG (Metaset Third Generation) Avionic Test Bench. He joins SOGETI HIGH TECH early 2018 as a Delivery Manager, more eager than ever to involve himself in new challenges.
