Three Internet of Things (IoT) companies have demonstrated the first end-to-end IoT ecosystem designed with re-usable infrastructure and open industry standards for industrial and commercial applications at scale.
Advantech B+B SmartWorx, Connect2 Systems and DevicePilot delivered automatic remote monitoring and management of industrial ultra-low power IoT sensor devices using constrained wireless networks and open IoT standards developed by the Open Mobile Alliance (OMA) and Internet Engineering Task Force (IETF).
The demonstration featured Wzzard wireless sensor nodes from Advantech B+B SmartWorx and Inclinometer wireless sensor nodes from Connect2 Systems. The Wzzard wireless sensor nodes are typically used to monitor the energy consumption and the condition of equipment and facilities.
Examples where they have been used include: data centre temperature monitoring to reduce energy consumption; construction aggregate plant monitoring of ‘crusher’ drive motors and conveyor belts to enable predictive maintenance and reduce unexpected failures; and for use in creameries to keep everything at exactly the right temperature and the correct humidity to protect flavour and control bacterial growth.
The Inclinometer wireless sensor nodes are designed for near vertical borehole applications and are used to measure lateral movement in the ground or in a structure for applications such as detecting slopes and landslides; monitoring dams, retaining walls and bending in piles; detecting and recording ground movement due to tunnelling operations; and measuring settlement and deformation of concrete slabs and tank bases.
The end-to-end solution, demonstrated at the recent Internet of Things Thames Valley Meetup in the UK, showed the benefits of true interoperability, extensibility and reuse from using industry standards including:
• 802.15.4e for the air interface (802.15.4e – an IEEE standard for low-power, time synchronised short-range wireless connectivity)
• 6LoWPAN - IPv6 over Low power Wireless Personal Area Networks (enables relatively large IPv6 packets to be sent over small radio networks such as 802.15.4)
• IETF CoAP for a RESTful API (CoAP – Constrained Application Protocol for edge devices. This IETF protocol brings the benefits of a RESTful API for to constrained edge devices)
• OMA Lightweight M2M (LWM2M) device management standard (a lightweight machine-to-machine interface for device management, defined by the Open Mobile Alliance)
• Internet Protocol for the transport to the Cloud.
The automatic monitoring and management of the wireless sensor nodes was performed using DevicePilot universal cloud-based software service connected to a LWM2M server running on IBM’s Bluemix Cloud Platform.
This was in turn connected to an Advantech B+B SmartWorx cellular gateway running Connect2 Systems edge gateway/LWM2M Client software. The sensor data was sent to a business application running on IBM’s Watson IoT platform.
"A huge amount of 'care-and-feeding' surrounds every IoT application and in our experience, this can often consume some 80% of the overall effort," said DevicePilot CEO Pilgrim Beart (pictured).
"This extra work includes setting-up and managing connectivity, security, monitoring, provisioning and code upgrades. In the past, manufacturers have implemented these functions in a proprietary way, which had the side-effect of locking the application into a closed silo, so no part of it could easily be used by third-parties or supplied by third-parties.
“This lock-in was dangerous for the customer and inefficient for the vendor and the need to translate between proprietary edge protocols and the cloud created real security vulnerabilities."
Beart continued: "Using standards, which are entirely open and compatible with Internet Protocol allows easy re-use and integration of all components in the chain, from the edge device, through the gateway to cloud services, while also enabling end-to-end security. This brings huge efficiencies to vendor and customer alike, finally delivering the win-win benefits long promised by IoT."
“This is the first public demonstration of open, standards-based, end-to-end IoT device management, which we’ve built using commercially-available technology and industrial IoT devices,” said Duncan Purves, co-founder, of Connect2 Systems.
“Manufacturers and suppliers are under pressure to shorten the time-to-market of new products, which means they may be shipped and deployed with embedded software bugs or features missing.
“Industrial IoT devices are typically deployed in inaccessible places and the cost of servicing the devices manually to upgrade the firmware or change configuration settings can be prohibitive.
“Security is also a key concern; in fact, history shows us that all software stacks have security bugs, which will need to be patched after deployment and therefore the ability to update software/firmware ‘over- the-air’ (OTA) for long-lived lifetime of industrial IoT devices is essential,” said Purves.
“The Open Mobile Alliance is pleased to see another successful implementation of the Lightweight M2M (LwM2M) specification,” said Seth Newberry, general manager of the Open Mobile Alliance. “Interoperability is key to achieving the potential of IoT, and this demonstration illustrates how using standard protocols like LwM2M enables market growth and a healthy ecosystem.”
Mike Fahrion, VP IoT Technologies at Advantech B+B SmartWorx, said: “Reducing the friction in deploying and supporting IoT solutions is core to our strategy as an IoT hardware platform provider. By developing intelligent hardware platforms for the network’s edge, we enable systems integrators and solutions providers to deploy scalable IoT solutions.
“The work done by Connect2 Systems demonstrates that IoT solutions can be deployed using an end-to-end standards based approach that will be required for successful, cost effective, secure and scalable IoT deployments.”
