How we got to IoT
Industrial revolution started a rapid increase of production efficiency, as well as more intensive specialization all around the world.
While the 1st and the 2nd industrial revolutions mainly concerned machinery and its utilization, the 3rd and 4th industrial revolution started to make life easier also to people outside manufacturing industry.
The 1st industrial revolution occurred at the turn of the 18th and 19th century and started in England where the first textile processing factory was introduced. Since then, the dress-makers no longer had to make every product manually, but textile production started to relocate to weaving factories. And it was not only about the textile industry, hand-making started to turn into manufactories in general.
Liking for machines was increasing. They started to be made also for private use. And as the machines were mostly made of metal, the machine-building industry and metallurgy also started to grow to support production of metal and raw materials required for machine-building. This, as a result, influenced transport business, as it is clear that horses and people could not manage to transport the required volumes of metallurgical materials. So the first steam locomotive was introduced to the world in 1800. The steam engine is considered the symbol of the first industrial revolution to date.
The 2nd industrial revolution occurred in 1870s and is associated mainly with electrification and introduction of assembly lines. Edison introduced a bulb to the world and electricity started to be used not only for production, but also in transport, whether for private electro-mobiles or public tram transport.
Scientists also started to acquire new knowledge of a human and of nature in this period of time. Darwin came up with the theory of evolution, Newton discovered the laws of physics including application thereof, X-rays were discovered, Planc comes with quantum physics and Einstein with theory of relativity. Perception of the world starts to change significantly.
The 3rd industrial revolution is a recent thing and dating thereof is very disputable. It is mostly attributed to the end of the 20th century. Its biggest benefit is process automation. This is one of the reasons why its commencement is associated with manufacture of a programmable logic controller, i.e. industrial computer - a control unit for real-time process automation. The 3rd industrial revolution is, therefore, often associated with digitalization.
The 4th industrial revolution is occurring now. It is characterized by mass growth of internet and its use almost in every area. This is also associated with work automation and its influence on the labour market. A lot of tasks can be performed fully automatically or remotely in real time. Sensors, chips and other devices can collect data and process it. Internet has become an instrument not only for work, but also for communication. This is also related to social changes which we note in this period of time. We are assumed to continue witnessing the 4th industrial revolution for the next 20 to 30 years. We are not able to fully imagine where it will take us with current pace of development in the end.
Start the 4th industrial revolution also in your company and keep up with the times!
