The machine product system is a definition of technology by which a process or procedure is carried out with minimum human guidance. It is also known as automatic control. Features of the machine product system and examples.
Several control systems handle equipment, such as factory processes, machinery, telephone connections, boilers and furnaces for heat treatment, stabilization and control of ships, aircraft and other vehicles, and applications with minimal or reduced human intervention.
The machine product system covers different types of applications ranging from a home thermostat that controls a boiler to a large industrial control system with tens of thousands of input measurements and output control signals.
In terms of control complexity, it can range from simple on / off control to high-level multi-level transmission algorithms.
This system has been achieved by various means, such as pneumatic, hydraulic, mechanical, electronic, and computer units, generally combined with each other.
Sophisticated systems, as seen in recent factories, aircraft and ships, often use all these techniques combined.
2.1 Industrial robotics
2.2 Programmable logic controllers
Flexible and precise machine systems for products are crucial for the profitability of processing and production processes.
Developing applications for plant monitoring and control can be challenging, as testing applications in real plants is expensive and dangerous. System developers often rely on simulations to test their solutions before implementation.
They can also be maintained through simple quality control. However, not all tasks can be automated at this time, and some tasks are more expensive to automate than others.
Machines can perform tasks that are performed in hazardous environments or that do not meet human capabilities, as they can operate even in extreme temperatures or in radioactive or toxic atmospheres.
- Higher performance or productivity.
- Improving quality or greater predictability of quality.
- Improving the consistency and reliability of processes or products.
- Greater consistency of results.
- Reduction of costs and direct costs of human labor.
- Installation in operations reduces cycle time.
- You can perform tasks where high accuracy is required.
- It replaces human operators with tasks that involve strong or monotonous physical work. For example, use a forklift with one driver instead of a team of several workers to lift a heavy object that reduces some occupational injuries. For example, less back strain the lifting of heavy objects.
- Replaces people with tasks performed in dangerous conditions, such as fires, space, volcanoes, nuclear facilities, underwater, etc ..
- Performs tasks that go beyond human capabilities in size, weight, speed, resistance, etc ..
- Significantly reduces working time and working time.
- Free workers from other roles. Provides a higher level of work in the development, implementation, maintenance and implementation of machine systems products.
- Some research seems to suggest that a machine product system can have detrimental effects beyond operational problems. For example, the relocation of workers due to the general loss of jobs.
- There may be security threats or vulnerabilities because there is a greater relative propensity for error.
- Unforeseen or excessive development costs.
- The initial cost of installing the equipment in the factory configuration is high, and failure to maintain the system can lead to the loss of the product itself.
- This leads to more damage to the environment and can exacerbate climate change.
One trend is to increase the use of machine vision to provide automatic control and robot control functions. Another is the constant increase in the use of robots.
It is a division in the machine product system that supports several production processes. Such production processes include welding, machining, painting, materials processing and installation.
Industrial works use various software, electrical and mechanical systems that allow to obtain high speed and accuracy, which far exceeds the quality of human work.
The birth of the industrial robot took place shortly after World War II, as the United States saw the need for a faster way to produce industrial and consumer goods. Digital logic and solid-state electronics have allowed engineers to build better and faster systems. These systems have been revised and improved until one robot can operate with little or no support 24 hours a day.
For these reasons, in 1997 there were about 700 thousand industrial robots, and in 2017 their volume increased to 1.8 million dollars.
In recent years, artificial intelligence has also been used with robotics to create automated labeling solutions using, for example, robotic weapons. Automatic label applicator, as well as artificial intelligence to study and identify products to be labeled.
Programmable logic controllers
The production machine uses programmable logic controllers (PLC) in the production process.
PLCs are similar to computers. However, computers are optimized for calculations, while PLCs are improved for industrial use and for control tasks.
They are built in such a way that requires only a basic knowledge of logical programming, as well as the handling of vibration, noise, humidity and high temperatures.
The main advantage of PLCs is their flexibility. Thus, with the same basic controllers, the PLC can handle a wide range of control systems.
You no longer need to reconnect the system to change the management system. This feature creates a cost-effective system for complex control systems.
