Machine vision systems and industrial computers in industrial automation

There are five main reasons to use machine vision systems in industrial automation control:

1. Accuracy

Due to the physical limitations of the human eye, machines have obvious advantages in terms of accuracy. Even if the human eye relies on a magnifying glass or microscope to inspect a product, the machine will still be more accurate because it can be accurate to one thousandth of an inch.

2. Repeatability

The machine can do the inspection job one at a time in the same way without getting tired. In contrast, the human eye will make a slight difference each time it detects a product, even if the product is exactly the same.

3. Speed

The machine is able to inspect products faster. Especially when inspecting objects moving at high speeds, such as on production lines, machines can increase productivity.

4. Objectivity

There is also a fatal flaw in human eye detection, that is, the subjectivity brought by emotion, the test results will change with the mood of the worker, while the machine has no joy, anger and sorrow, and the test results are naturally very considerable and reliable.

5. Cost

Since machines are faster than humans, a single automatic inspection machine is capable of taking on the tasks of several people. In addition, the machine does not need to stop, does not get sick, and can work continuously, so it can greatly improve production efficiency.

The use of machine vision systems can not only quickly obtain a large amount of information, but also easy to process automatically, and is also easy to integrate with design information and process control information, therefore, in modern automated production processes, machine vision systems are widely used in industries such as working condition monitoring, finished product inspection and quality inspection. Machine vision systems are characterized by a high degree of flexibility and automation in production. In some not very good environments, it is not suitable for manual work or artificial vision is difficult to meet the requirements, and machine vision is often used to replace artificial vision; At the same time, it is applied in the process of mass industrial production, and the machine vision inspection method can greatly improve the production efficiency and the degree of automation of production. Moreover, machine vision is easy to integrate information, which is the basis for realizing digital manufacturing.

Therefore, machine vision and industrial automation are indispensable, machine vision is a branch of automation, and there can be no machine vision without automation. Machine vision has the characteristics of fast speed, high precision and low noise in the use process and can adapt to most of the harsh environments, etc., and its application in the field of industrial automation can replace the production mode based on manual and machinery, improve production efficiency, and greatly save the cost of manpower and mechanical maintenance. In addition, machine vision technology can also effectively improve the accuracy of industrial automation production, thereby promoting the good development of the industrial industry.

   Industrial computers in industrial automation

If ordinary computers are used in industrial automation, the failure rate is high, which increases maintenance costs. The performance of the industrial computer is relatively stable, and the upfront cost is higher than that of ordinary computers, but from the perspective of long-term use, it saves unnecessary maintenance costs. And the control computer can be operated 24 hours a day. The industrial computer does not have high requirements for the use environment, and can be professionally protected and tested in dustproof, moisture-proof, vibration-proof, etc., and can be used in any complex and harsh industrial environment, and can adapt to the environment. In addition, the industrial control computer is equipped with Linux, server and other industrial control server systems, the safety and reliability are higher than the ordinary windows system, and the risk of poisoning is lower than that of ordinary computers.

An industrial computer can be simply thought of as a controller in an industrial automation machine. In addition to mechanical parts, a machine and equipment, from the input of data and signals to the action of the whole machine, can produce the key component of "automation" ability, which is the controller. In fact, automation is the process of automatic execution of "programs" by machine parts, and each instruction in the program is analyzed and issued by the controller, so as to achieve the goal of automatic work of all parts of the machine.
