We learned from history that there has been a long industrial revolution in human history. This change, which began in the second half of the 18th century, has spawned countless modern factories that supply goods to meet the needs of the world.
According to the study of many historians, the industrial revolution happened three times. The first revolution was marked by the use of steam power, the second sign was the birth of the assembly line, and the third sign was the burgeoning of early automation technology.
Now, we have now unveiled the fourth industrial revolution, the realization of machine intelligence through advanced integrated circuits (ICs), which in turn drives the entire process of change. And we are at the forefront of this revolution, facing many challenges and opportunities.
In the fourth industrial revolution, we improved the quality of the machine by improving the intelligence of the machine, thereby improving the quality of the entire manufacturing process; on the other hand, we can continue to maintain the advantages of low cost and meet the needs. The need for flexibility in goods worldwide.
Until recently, for most companies, the flexibility to implement manufacturing processes on the factory floor was still elusive. Machines on the same assembly line are primarily used to implement a particular function. Making changes on the product line means that it takes a lot of time to adjust the equipment, which is a double waste of time and money.
However, the higher the degree of customization or differentiation of the product line, the more obvious its competitive advantage. With smart devices, intelligent factories can respond to such changes in an automated manner, reducing the scale of production lines and avoiding significant cost increases.
However, building this level of flexibility is not easy. This means that every piece of equipment in the factory must be “intelligent,†also known as “control intelligence.†That is, we must work to improve the intelligence level of the control system so that it can automatically respond to perceived events in the production environment. For example, a small screwdriver on the assembly line must also be able to automatically adjust the torque depending on the type of material being processed (eg steel, carbon or plastic).
And so on to the entire factory floor, there may be millions of device nodes that need to implement control intelligence.
Highly flexible plants must also have the most advanced communications infrastructure. When a product change occurs, a smart factory with advanced communication tools can quickly adjust production based on data entered in the sales department, or even make product-by-piece product adjustments directly based on sales orders.
These communication systems can be in wired and wireless form, but must be able to process large amounts of data without consuming a lot of power resources.
When the communication flow for order and product changes is transmitted in one direction, data about the state of the factory floor is transmitted in the opposite direction.
The more data that can be exchanged at a faster rate, while the less power resources are consumed, the more cost-effective, more reliable and flexible the entire plant.
The fourth industrial revolution will also create a new era for plant reliability and safety. Automated sensors deployed throughout the production line will help preventive maintenance, so you can repair your equipment before it fails, saving you time and money.
These well-maintained machines also increase the safety of factory floor workers. The robot no longer needs to be enclosed behind the wall because the sensor and control intelligence can indicate if someone is nearby and automatically adjust its position.
These sensors will become the "eyes and ears" of the factory, they power themselves through energy harvesting, and they are small and sturdy enough to withstand extreme temperatures and vibrations. Most importantly, because sensors need to be deployed throughout the plant, they must be inexpensive.
Engineers at Texas Instruments (TI) have created such low-cost, low-power, highly reliable, high-processing control intelligence, communication and auto-sensing ICs, leading the fourth industrial revolution, and every day TI engineers are breaking through. The limits of the factory environment. It remains to be seen how highly integrated ICs will permanently change the way products are produced.
