The Application of Industrial Computers in Machine Vision Systems

In today's constantly upgrading industrial automation, machine vision systems are gradually replacing manual inspection and are widely used in industries such as 3C electronics, food packaging, and pharmaceutical testing. In the entire system, industrial computers play a crucial role as the core control unit.

1、 Machine vision systems use industrial cameras, light sources, lenses, and algorithms to make devices "visible and accurate". Standard structural components: industrial camera (image acquisition), light source system (fill light), lens (imaging), image processing software, industrial computer (core processing unit), control execution mechanism (PLC/robotic arm, etc.), where industrial computer=brain, responsible for image processing, logical judgment, and control output.

2、 The core role of industrial computers in machine vision systems

(1) The image data processing center (core computing power) is responsible for high-speed processing of images captured by cameras, including defect detection (scratches/bubbles/flaws), size measurement (accuracy up to micrometer level), OCR character recognition, positioning and guidance (robotic arm grasping). Without industrial computers, the vision system cannot operate.

(2) In actual production lines, the visual system of the multi device collaborative control center not only "looks", but also "controls": communicates with PLC (controls equipment actions), links with robotic arms, and interfaces with MES systems

Industrial computers are responsible for:

data interaction

command delivery

Real time response

(3) High speed data transmission and interface support. Machine vision has extremely high interface requirements, and industrial computers usually need to support: USB 3.0/USB 3.1 (industrial cameras), Gigabit/10G Ethernet ports (GigE cameras), COM ports (docking with PLC), HDMI/DP (display output). The richer the interfaces, the stronger the system scalability

(4) 7 × 24-hour stable operation guarantee. Machine vision is commonly used in automated production lines, requiring long-term continuous operation, high stability, and strong anti-interference ability

Industrial computers have:

industrial-grade motherboard

Fanless cooling design (dustproof and oil proof)

Wide temperature/wide pressure support ensures that the visual system "does not disconnect or misjudge"

(5) With the development of AI vision, industrial computers are gradually undertaking tasks such as running deep learning models, AI defect detection, and intelligent classification and recognition ,High performance industrial control computers (i5/i7+GPU) have become a trend
