IIOT (Industrial Internet of Thing or Industrial Internet Things both are same )

Let’s first understand what is meant by Internet of Thing, it is the network of interconnect devices which communicate with each other through the internet. These items are embedded with some sensing device that is connected to the internet in order to pass the information to other devices which are used to control or monitor the behavior of plant, environment etc. However, these sensors need to be more accurate and able to work in hazardous conditions with good efficiency and accurately. Due to advancement of technology, nowadays we have a range of chips available which can sense the information, compute and communicate it in real time. Below figure shows the basic block diagram of Internet of Thing.

One of the major applications of IOT is in “Manufacturing Industry”, here the technology is known as “Industrial Internet of Thing”. This has enabled the industries to acquire the huge amount of data, at a faster speed with good accuracy than older times. The cloud which aggregates all information and presents it to end user in a readable manner. The use of IIOT is increasing heavily in the industries due to intelligent devices.

 

Advantages of IIOT:

Industries have been benefited by the use of IIOT in their plants which helped them to safety, cost-saving, time-saving, maintenance, scalability, efficiency. It is possible to monitor people, data and processes from the remote shop floor to offices, as this has helped higher authorities to take effective decisions based on the visual reports.

 

Protocols and Challenges:

As Industrial Internet Things (IIOT) makes use of a range of devices which are interconnected to each other, these devices work on different protocols to communicate data among themselves. To overcome this problem there are a number of communication protocols available such as OPC-UA, Message Queuing Telemetry Transport(MQTT) protocol is being widely used as a messaging protocol for industrial application due to low overheads, two-way data communication, publish and subscribe methods to inject data into SCADA applications.

The major challenges that Industrial Internet Things IIOT face are the interoperability between machines which use different protocols and architectures, and security to transmit faithfully information over and over. As increasing vulnerability in the security of sensors which has given rise to MQTT since it is very secure protocol. It is important to secure data during transmission by encrypting it sender end and decrypting it receiver end.

 

Applications:

There is increasing trend of IIOT in the variety of industrial application such as:

  1. Automotive
  2. Healthcare
  3. Retails
  4. Energy
  5. Smart Transportation/Manufacturing/Buildings/Homes

Let’s discuss one of the applications in detailed.

 

Smart Manufacturing:

Manufacturing is the most impacted sector after the revolution of IIOT. This is not only responsible for making management effective but also smarter work. IIOT have radically improved the manufacturing by viewing each unit of production rather than batch-level production. This has given rise to Smart Manufacturing, it has built the environment which can access all the information in real time within the plant and transfer it to business leaders in visual form which could help to take required actions.

In the recent survey of SCM(Supply Chain Management) on Smart Manufacturing and IOT, it is claimed that one in five today will admit offline operation, which will be fall approximately to zero in five years. As per data of Visibility Maturity Model, 50% except to have visibility across the supply chain whereas 10% assume to single factory level and control which is 75% as per today’s figures.

Industrial Internet Things - visibility of maturity model

Smart Manufacturing allowed industry for full visibility of manufacturing process of product and maintaining/optimizing the supply chain. Smart Manufacturing should be made more intelligent and have automatic analytics capabilities. This would help organizations to take appropriate business decision for the growth of business and delight customers with a capable and accurate solution.

It requires the powerful technology which can make all machines work simultaneously within specified tolerance level. Additionally, IOT has the capability to create a network which can link manufacturing assets from machines to end product being produced, also from a sensor incorporated in controls to measuring instruments. IOT has given digital image to the physical machines which enabled people to monitor the behaviour of it in real time.

Below is the list of industries which have adopted this technology:

  1. Siemens
  2. Bosch
  3. Cisco
  4. Fiat Chrysler Automobiles
  5. Harley-Davidson
  6. General Motors
