Peter Ruffley, CEO of Zizo, explains how edge IoT and analytics can provide a powerful mechanism for translating complex data sources into a streamlined, lower cost platform with faster return on investment and higher value.
A lot has been written about the IoT revolution and how the technology has the capability to revolutionise industries, transform productivity and unlock new levels of insight. But for those intrigued by the possibilities and looking to dip their toe in the water, the potential myths of high price point, infrastructure and connectivity challenges, as well as the required skill set can be significant hurdles that seem insurmountable.
In addition, especially when it comes to the reality of industrial IoT, the cost, time and disruption that goes into a brand-new facility – the prospect of having to rip and replace new infrastructure to support IoT just isn’t a viable option for many businesses. So what’s the alternative? First, consider some of the key challenges businesses face when considering an investment in IoT.
The transformational potential of IoT across multiple industries is staggering and much has been discussed about its power to revolutionise business models. But while the possibilities for market sectors are hugely exciting, the reality of many of these industry IoT solutions is that they are designed for vast use cases – the setups are intricate and complex, with incredibly powerful networking capabilities that require significant investment and skill to execute. In addition, the major players in the IoT space, including AWS and Microsoft, require huge upfront investment into IoT stacks and other hardware integrated into the data centre, as well as personnel who can code it, write it and build it – that’s potentially hundreds of thousands of pounds even before any potential data or insight has been gained.
Return on investment is something that has been lacking within the IoT space, causing proof of concepts to fail. When you consider one of the early use cases for IoT – smart meters – in that instance it’s simple to work out the RoI as you don’t have to send meter readers to sites, there is an immediate cost benefit. But with industrial IoT, it’s much more than that. Perhaps it will expose some savings, maybe less machine maintenance will be required. Savings are harder to identify at the outset, therefore, large upfront investment is difficult to justify.
Rip and replace
In a lot of industrial cases, the existing machinery that requires monitoring consists of large, complex and expensive structures. They are ideal for the task at hand and, for that reason, they should not necessarily be interfered with, and instead be monitored in a non-invasive way.
Many state-of- the-art facilities have been designed and built at the cost of billions of pounds; you can’t start ripping and replacing components because cloud-enabled technology will provide a benefit that hasn’t been quantified yet. Yet, conversely, many of the IoT options out there from the major players in the market depend on being built in from the start, a concept that could result in significant business disruption and downtime.
Skillset
The skillset that is required to manage these types of complex setups is also a significant hurdle for many organisations. A high proportion of IoT customers in manufacturing are not necessarily IT-savvy in the same way as traditional database users. So, with many providers requiring someone with the skills to exploit these platforms effectively, this is an issue that is damaging the chances of adoption in that sector.
Can a business really afford to hire a dedicated IoT professional? How can they support the business in other ways outside of that role so they add as much value as possible? In reality, businesses need a way to get data out of the IoT devices without the complex ecosystem that surrounds them, through a streamlined platform that only needs a browser to access.
Infrastructure
Another stumbling block for many IoT projects is where the infrastructure isn’t developed, if the location is in an inconvenient place without reliable wifi – the only clouds available are the ones floating in the sky. In this case, having an IoT service that collects all the data, analyses them at the point of collection and enables rapid and reliable visibility of what’s going on can make all the difference and is a much more pragmatic, both in large factories and distant locations. That’s the difference between the original vision of IoT and what it actually is in practice.
IoT at the edge
The vision of IoT and the actual reality are very different. A yes or no response from a sensor is not the same as figuring out whether a complex piece of machinery is acting as it should and to optimum efficiency levels. It’s not just about the opportunity to collect data, but also having the capability to modify that data collection, to add additional sensors to expand the data gathered even further.
For example, it could be that the installation is monitoring temperature and speed, but actually you also need to measure vibration. Another sensor is therefore required, so you need a platform that’s adaptable and scalable. In the current industrial sector environment, you need to be flexible and ready to change in scale, both in terms of the size and complexity of the data that are being gathered.
With the concept of edge computing and analysing data where they are created, fast gaining momentum, organisations are discovering how they can quickly access only the most valuable data, in real time, which will prove mission-critical to their business.
Coming back to the smart meter example – this type of IoT deployment involves millions of identical devices with the same data and a single purpose. It’s still an investment, but the principle is simply connecting multiple homogeneous devices together. This is unlike today’s industrial environment, where there could be a handful or even tens of thousands of different devices, all doing slightly different tasks in different ways. This specialised equipment therefore requires an IoT edge product that can accurately translate, measure and analyse different, incompatible and comparable data formats as they arrive without having to rip and replace internal electronics of the machinery being measured.
Edge computing enables data processing to be performed on the edge nodes prior to transmitting only the aggregated data to the central server. So, instead of transmitting huge volumes of data every minute, this could be reduced to just a couple of messages every five minutes, depending on what is being measured and for what purpose. This results in a massive reduction in bandwidth and means that using the cellular network becomes cost-effective, thereby reducing infrastructure costs and creating a quicker return on investment and value.
For businesses looking to get started in IoT, the edge negates the need for a massively complex and costly deployment. Instead, it provides a simple entry capability to get a project up and running quickly, to provide data points and rapid insight into how a business can capitalise further with a data-led strategy, all at a reasonable price point.
Use cases
When considering data collection and analysis within the health and personal care industries, this is typically restricted to laboratory and scientific environments. In most cases, this is an essential strategy to record and analyse data in a clinical setting against control data. But if these data are designed to inform decision making, is such an environment providing the most granular and relevant insight for optimum decision making? What if we were to move away from the laboratory environment and take these data to the real world using innovative technology?
There’s now an opportunity to integrate multiple data sources via IoT sensors with other data reference points, to understand properly the context in which consumers or trial subjects use personal health devices and the other interactions that can come into play.
For example, combining data from multiple types of IoT devices and pulling those data to a centralised point; using cross-sectional studies to generate volumes of data over a longer period of time, not only at a certain time each day; and using proactive questionnaires for a subjective measure of an individual’s activity and opinions. Taking the science out of the lab and combining clinical data with behavioural data in people’s everyday environment will create vast amounts of new knowledge. It’s more than just a holistic approach, it’s a completely new approach that has never been done before.
Furthermore, Zizo has partnered with Safran Landing Systems, which is a partner to 30 leading commercial, military, business and regional airframers. The operation and maintenance of test rigs, equipment used for testing purposes, is an essential component of Safran’s assembly shop. Safran was looking to explore advanced technology that can provide better visibility both in terms of the test rig performance and those influencing the test results. Integrating these in an intelligent way will control parameters, monitor routines and implement preventative measures.
To overcome this challenge, Zizo has built a portable edge industrial internet of things (IIoT) analysis platform, using data analysis software to provide big data capability. This will create a repository and platform to manage data from across teams and across functions. This end-to-end connected edge device also combines device management and analytics in one platform, without the need for implementing a factory-wide network. The potential of edge IoT technologies is vast and, in this instance, can improve productivity across the manufacturing sector, helping businesses accelerate their move towards manufacturing 4.0.
Conclusion
While the vast capabilities of IoT deployments are widely publicised, many businesses are unfamiliar with the availability of simple, affordable entry IoT capabilities to provide data analysis down at the edge, where only the most valuable data collected will be shared and in real time, making the process more cost-effective to the business.
The big business offerings touted by the likes of AWS and Microsoft have their place, but for the majority of businesses without the huge use cases to warrant the dedicated attention and support from the major players, they will be left to their own devices to achieve their desired value. Instead, a small-scale offering that incorporates big data, edge and IoT within a small footprint will actually have a significant impact, and one which is also easily scalable without having to overhaul existing infrastructure.
