IoT-enabled predictive maintenance

What is Predictive Maintenance?

Predictive Maintenance is proactively figuring out when an asset should be maintained based on its actual state, rather than on a fixed schedule.

The Need for Predictive Maintenance

Unplanned Outages
Unplanned equipment downtime can mean big losses in revenues and productivity. For example, some of the leading automotive manufacturers estimate that unplanned downtime can cost them as much as $15,000 – $20,000 per minute and a single downtime event can cost approximately $2 million.

Unnecessary work
Performing preventative maintenance regardless of the condition can lead to unnecessary costs and delay.

Fundamentally Reactive
Limited to no analytic modeling capabilities to prevent and predict issues before they impact.

How can IoT-enabled predictive maintenance transform your business?

In Virginia last year, an airplane was grounded by an unlikely adversary: a large swarm of bees. The peculiar story made for great newspaper headlines and serves as a reminder that even with the best technology and planning, some things are truly unexpected. But fortunately, most aircraft delays are caused by far more predictable issues than an unwelcome swarm of bees nesting in a turbine. Airlines, like most asset-intensive businesses, are getting increasingly better at predicting failures and anticipating maintenance problems. Rather than keeping planes grounded for costly and annoying last-minute maintenance — or, worse, exposing passengers to the risk of flying on a faulty aircraft — airlines are investing in cutting-edge technology that detects potential problems before they arise. Wouldn't it be nice if you could be alerted to equipment failures or maintenance issues before they happen? That’s where the real possibilities of IoT-enabled predictive maintenance is going to be useful.

IoT enables companies to solve problems before customers realize they exist, resulting in reduced downtime and maintenance costs, hence better customer experience. Machines and equipments are fitted with sensors such as temperature, pressure, vibrations/second, noise levels, etc. These sensors continuously monitor key attributes or performance indicators — such as temperature, pressure, vibrations/second, noise levels, etc. Utilizing IoT and sensor data from connected equipments, businesses can now gain visibility into the condition of their valuable assets and specific components in real time. Organizations are also using advanced analytics and machine learning to detect anomalies or patterns that are indicative of failure and intervene as soon as initial signs of failure are detected to perform the right maintenance activities. Early detection helps in reducing failures and costs.

Examples of IoT-enabled predictive maintenance

For a great example of how IoT-enabled predictive maintenance can transform business, let's look at a steel manufacturer with multiple plants. Each plant has multiple arc furnaces that use water cooling panels for temperature control. However, leakages in the panels were causing safety issues as well as production losses. To resolve this issue, the manufacturer build IoT solution that remotely monitors the panels, detects anomalies, and performs root-cause analysis. The implementation of predictive maintenance has prevented failures and production delays throughout the plants while helping ensure employee safety.

In another example, aircraft engine manufacturer Rolls-Royce implemented predictive maintenance on IoT platform to help their customers reduce costly flight delays caused by engine maintenance issues. Each of their 13,000 engines in operation worldwide has thousands of sensors that monitor engine components and deliver insights around fuel efficiency, engine performance, and operational efficiencies. These insights enable Rolls-Royce to anticipate maintenance needs and avoid costly, unscheduled delays.

In short, the IoT wave has simplified plant equipment maintenance, while externally it has enabled manufacturers to enhance customer support services.


  1. his is my first time i visit here. I found so many entertaining stuff in your blog, especially its discussion. From the tons of comments on your articles, I guess I am not the only one having all the leisure here! Keep up the excellent workjogos friv gratis

  2. I knew at a young age that the nasty green shot you got at the health food store or juice bar, that was followed with an orange squad (yes, an orange wedge, but I called them squads) was good for me, but I had no idea why, the same kinda follows now, except I know a few more details about it's real health benefits, because I am genuinely interested in what it provides to my overall well-being.

  3. Anni Putur, Maddi Tassey, Cam Boyce, Gabby Trongone, and Camille Miller were relentless on defense keeping Nauset to one 2nd half goal. Kasey Molito had another brilliant game with 10 saves on 14 shots. Bonavita was absolutely brilliant on offense as she scored 5 goals and kept the ball away from Nauset for most of second half.

Narrowband – IOT

Narrowband-IoT (NB-IoT) is a new technology standard, designed to broaden the future of IoT connectivity. Ratified by the 3GPP, a telecoms standards body which works to develop future generation wireless technologies, NB-IoT will soon be deployed by operators across the globe.The technology was developed to enable efficient communication and long battery life for mass distributed devices across wide geographical footprints and deep within the urban infrastructure. In other words, (NB‑IoT) is a new way of communicating with “things” that require small amounts of data, over long periods, in hard to reach places. Narrowband IoT (NB‑IoT), also known as LTE Cat NB1, is a Low Power Wide Area (LPWA) technology that works virtually anywhere. It connects devices more simply and efficiently on already established mobile networks and handles small amounts of fairly infrequent 2‑way data, securely and reliably. And the best is, it provides: very low power consumption excellent ext

Human Microchipping, The Benefits And Downsides

The beginning of human microchipping technology makes it possible, among other things, to instantly verify whether a person is who he says he is. An RFID (short-range radio frequency identification) implant can hold all the information we usually carry in our wallets. It can transmit our identity information as we walk through a security checkpoint, enable us to use public transport and make long lines at the supermarket checkout a thing of the past. The future of microchipping is exciting, with many interesting potential applications. Chips like the ones we now use in our pets could become commonplace in the next decade. Of course, there are a few downsides to the technology. But while some experts have their doubts about whether these chips are appropriate for use in humans, the fact that they could offer many advantages is indisputable. The RFID chip is basically a tiny two-way radio, roughly the size of a grain of rice, capable of containing various types of information. It i

Which are the communication protocols used for IOT?

One of the essential factors of the IoT are communication protocols. One of the key aspects of the IoT is the communication between devices and it will be provided with communication protocols. The following paragraphs will provide a brief overview about each of the Internet of Things communication techniques. 6LoWPAN 6LoWPAN that is a IP based communication protocol is an acronym of IPv6 over Low Power Wireless Personal Area Network. 6LoWPAN, therefore, allows for the smallest devices with limited processing ability to transmit information wirelessly using an internet protocol. The most important detail of 6LoWPAN is IPv6. IPv6 (Internet Protocol version 6) is a 128-bit internet protocol developed due to inability of 32-bit IPv4 in addressing. While IPv6 developed, rapid increase of the number of connected devices has been considered. MQTT (Message Queue Telemetry Transport) It was created about 15 years back for monitoring remote sensor nodes and is designed to co
