The so-called machine vision is to use machines to replace human eyes for measurement and judgment. The machine vision system refers to the conversion of the captured object into an image signal through a machine vision product, which is sent to a dedicated image processing system, and converted into a digital signal based on pixel distribution and brightness, color and other information; the image system performs various operations on these signals To extract the characteristics of the target, and then control the operation of the equipment on the spot according to the result of the discrimination.
Why use a machine vision system?
There are five main reasons for using machine vision systems in industrial automation control:
Accuracy-Due to the physical limitations of the human eye, the machine has obvious advantages in accuracy. Even if the human eye relies on a magnifying glass or microscope to inspect the product, the machine will still be more accurate because its accuracy can reach one thousandth of an inch.
Repeatability-the machine can complete the inspection work again and again in the same way without feeling tired. On the contrary, the human eye will be slightly different each time the product is tested, even if the product is exactly the same.
Speed-the machine can detect products faster. Especially when detecting high-speed moving objects, such as production lines, machines can improve production efficiency.
Objectivity-There is also a fatal flaw in human eye detection, which is the subjectivity brought by emotions. The detection results will change with the mood of the workers, and the machine has no joys and sorrows. The detection results are naturally very impressive and reliable.
Cost-Since machines are faster than people, an automatic inspection machine can take on the tasks of several people. And the machine does not need to stop, not get sick, and can work continuously, so it can greatly improve production efficiency.
Because the machine vision system can quickly obtain a large amount of information, and it is easy to process automatically, and easy to integrate with design information and processing control information, therefore, in the modern automated production process, people use the machine vision system widely for condition monitoring and finished product inspection And quality control. The characteristic of the machine vision system is to improve the flexibility and automation of production. In some situations that are not suitable for dangerous work environment or artificial vision that is difficult to meet the requirements of manual work, machine vision is often used to replace artificial vision; at the same time, in high-volume industrial production processes, the use of artificial vision to check product quality is inefficient and the accuracy is not high , Machine vision detection method can greatly improve production efficiency and production automation. Moreover, machine vision is easy to realize information integration, and it is the basic technology for computer integrated manufacturing.
CSRME Safety Controller is developed for standard GB27607. By monitoring machine tool safety related equipment, the security of machine control system can meet the requirements of GB27607, and its security meets the requirements of ISO13849-1 (PLe) and IEC61508 (SIL3).
With rich interfaces, CSRME has limited programmable function. It can simultaneously replace many different types of safety control modules or safety PLCs, thus greatly simplifying the safety design of machine control systems and reducing cost.
