Applications of Industrial Control Computers in Machine Vision: So what is machine vision? Machine vision is the use of machines to replace human eyes for measurement and judgment. It is an important component of artificial intelligence. A machine vision system transmits image signals from machine vision products to a dedicated image processing system. Based on pixel distribution, brightness, and color information, it converts these signals into digital signals. The image system performs various operations on these signals, extracts the features of the target, and then controls the actions of field equipment based on the judgment results. Its advantages include high precision, high efficiency, high accuracy, and adaptability to complex environments.
Why are machine vision systems used in industrial automation control?
I. Accuracy - Due to the physical limitations of the human eye, machines have a clear advantage in accuracy.
Second, speed – machines inspect products faster. Especially when inspecting high-speed moving objects, such as on a production line, machines can effectively improve production efficiency.
Third, objectivity – another fatal flaw of human eye testing is the subjectivity of emotion, which depends on whether the staff member is in a good or bad mood. Machines have no emotions, so the results are naturally very reliable.
IV. Cost - Because machines are faster than humans, one automatic inspection machine can perform the work of several people. Moreover, machines do not need to stop, do not break down, and can work continuously, thus greatly improving production efficiency.
Industrial control computers have the following advantages in machine vision applications:
1. High speed: It can move up to 1000 meters per minute for overall inspection of strip appearance with an accuracy of 0.1 mm. It can also measure the specifications of individual pieces with a speed of several thousand pieces per minute.
2. Industrial control computers are of high quality, safe and stable. Industrial control computer technology has the characteristics of solid and stable performance. Machine vision design can work 24 hours a day without interruption. It has a set of teaching tasks to ensure that the functional testing of enterprise products is not lost. The disadvantage of manual testing is that the quality control is unstable.
3. There are no environmental limitations. Humans cannot work normally in environments such as high temperatures or confined spaces, but machine vision does not have such problems.
4. Compared to very small electronic components and connectors, which typically rely on microscopes and other technologies and low power consumption, machine vision can quickly measure any small-sized high-power magnifying glass.
