I. What are the differences between embedded industrial control motherboards and computer PC motherboards?
In addition, the industrial control motherboard is suitable for operation between -40 degrees and 90 degrees Celsius, and the temperature range and humidity ratio can also be between 0 and 95%. It also has strong self-radiation control, making it very suitable for normal operation in working conditions with metal dust or ordinary dust!
So, what are the differences between embedded industrial control motherboards and computer PC motherboards?
The biggest difference between industrial motherboards and regular PC boards is that industrial motherboards have more PCI slots, and some also have ISA slots, while regular PC boards generally don't. Industrial motherboards typically don't have graphics cards, whereas regular PC motherboards have PCI-E graphics card slots. Other CPUs are similar, except for embedded industrial motherboards which use dynamic CPUs.
In terms of functionality: Industrial control motherboards are designed for specific needs and functions. Through special design, they can implement functions such as automatic restart via watchdog timer and surge protection in case of abnormal situations such as system crashes, ensuring high system stability in harsh environments. Ordinary motherboards, on the other hand, cater to general needs and offer a wider range of functions.
In terms of stability: industrial control systems emphasize ultra-stability and zero failures; ordinary motherboards, on the other hand, boast impressive features and high performance, but how long they can withstand such demanding conditions depends on luck.
Cooling solutions: Industrial control motherboards prioritize heat dissipation efficiency, while ordinary motherboards focus more on appearance;
Industrial control systems have specific requirements, so the quantity is not large and they are expensive, while ordinary motherboards often rely on price to compete.
The above summarizes the differences between industrial control motherboards and ordinary motherboards. Generally, embedded industrial control motherboards are used in industrial applications because they are more stable. They are primarily suitable for industrial control equipment, GPS navigation, and other applications involving precise data processing. Some organizations require a stable system backend, which is where industrial control motherboards come in. They can help reduce costs, increase technological benefits, and lower labor costs, but their price is relatively high. The application range of industrial control motherboards is expanding, and their economic status is gradually increasing. Therefore, both embedded industrial control motherboards and regular PC motherboards play their respective roles.
II. What considerations should be taken into account when customizing industrial control motherboards?
Industrial control motherboard components are generally different from commercial materials, and need to take into account the requirements of industrial applications such as high temperature resistance and moisture resistance.
Platform options: Industrial control motherboards generally use low-power chipsets to save energy and improve environmental adaptability.
Interface Design: Due to the special applications of industrial control motherboards, interface design is often customized or incorporates a large number of standard interfaces to accommodate various needs. Common interfaces include serial ports, USB, LAN, and LPT. To adapt to the environment, they generally feature surge protection and electrostatic discharge (ESD) designs. Expansion interfaces include the PC104 family, PCI-E family, and PCI family, supporting multiple expansions when used with industrial motherboards and baseboards. They also include various display functions such as VGA, LVDS, HDMI, and DVI interfaces.
Life cycle: Industrial use prioritizes stability, therefore a long and stable supply cycle is desired to ensure the stability of the overall equipment or system.
Protection features: The industrial control motherboard is specially designed to automatically restart in case of abnormal situations such as system crashes, ensuring the system's high stability in harsh environments.
When selecting an industrial control motherboard, the first step is to examine its manufacturing process. To check the manufacturing process, first, assess the motherboard's workmanship: 1) Is the PCB (Printed Circuit Board) a multi-layer board (6 layers or more)? Are the solder joints and wave solder joints neat and concise? Is the wiring clean and clear? 2) Examine the motherboard components. 3) Check if the design structure meets future upgrade and installation needs, and whether the layout is reasonable and facilitates the installation of other accessories and heat dissipation devices. 4) Check if the motherboard has passed the relevant safety standard tests. Finally, check the motherboard packaging and related accessories, ensuring that all connecting cables, driver disks, warranty cards, etc., are complete.
