I. What are the characteristics of domestically produced industrial control motherboards?
For example, common domestic industrial control motherboards need to meet high and low temperature requirements and operate under high loads for extended periods without being shut down. Therefore, the design characteristics of domestic industrial control motherboards differ from those of ordinary motherboards:
Components: Industrial control motherboards differ from those of ordinary commercial motherboards. Industrial motherboards need to consider the requirements of industrial environments, such as high temperature resistance and humidity resistance. Common commercial motherboards prioritize cost-effectiveness.
Interface Design: Because industrial control motherboards are used in specialized environments, their interfaces are often customized or comprised of numerous standard interfaces to accommodate various requirements. For example, the KK-P251-B industrial control motherboard developed by Guangzhou Jinqili, based on the domestic Fit D2000/8 processor, features multiple display functions such as VGA, HDMI, and DP interfaces. It is one of the top choices for protecting information security.
Protection features: Industrial motherboards are specially designed so that the watchdog timer can automatically restart the system in case of abnormal situations such as system crashes, ensuring high system stability in harsh environments. However, to save costs, commercial motherboards generally do not come equipped with a watchdog timer.
In addition to the above, industrial control motherboards and ordinary motherboards also have the following differences:
First, in terms of functionality, industrial computer motherboards are generally designed to meet specific customer needs and functions, while ordinary motherboards cater to the needs of the general public and offer a variety of functions.
Secondly, there is stability. Industrial control emphasizes ultra-stable and fault-free operation; ordinary motherboards have cool features, great performance, and can run for a long time, which is something that ordinary commercial motherboards cannot guarantee.
Secondly, in terms of heat dissipation solutions, industrial control motherboards focus on heat dissipation efficiency, while ordinary motherboards focus on appearance design.
II. Structure and Classification of Industrial Control Motherboards
The hardware structure of an industrial control motherboard mainly consists of three parts: the chip part, the interface part, and the slot part.
The chipset of an industrial motherboard essentially determines all its functions. This includes the CPU type, system bus frequency, memory type, capacity and performance, and graphics card slot size. Industrial motherboards primarily feature: PS/2, USB, LPT (parallel), IDE, floppy drive, and COM (serial). Expansion slots are located on the motherboard and are used to mount expansion cards, connecting them to the system bus. Expansion slots are a way to add or enhance the functionality of an industrial motherboard; the type and number of expansion slots are important specifications.
There are three main types of industrial control motherboards: ATX motherboards, MicroATX motherboards, and mini ITX motherboards.
ATX motherboards: ATX is a motherboard specification established by Intel in 1995, representing the first major revolution in computer case and motherboard design in many years. A common ATX motherboard is a large rectangle with seven expansion slots, measuring approximately 305x244mm. ATX cardboard remains one of the most widely used cardboard types. For example, the Kingmax Phytium D2000 eight-core industrial motherboard uses the ATX version.
MicroATX motherboards are typically large squares with four expansion slots, measuring approximately 244 x 244 mm. MicroATX motherboards allow for four PCI expansion slots and two to three DIMM slots, reducing the width of the motherboard horizontally and reducing the total area by approximately 0.92 square inches.
Mini-ITX motherboards: Mini-ITX is a compact, miniaturized motherboard design specification defined and introduced by VIA. Currently, it is widely used by various manufacturers in a variety of commercial and industrial applications. It is designed for small professional computers in confined spaces, such as computers used in automobiles, set-top boxes, and networking equipment, but mini-ITX motherboards can also be used to manufacture thin clients.
These industrial applications all utilize industrial control motherboards, such as those for industrial control equipment, GPS navigation, online wastewater monitoring, online air quality monitoring, instrumentation, specialized equipment controllers, military applications, government agencies, telecommunications, banking, power, automotive LCD displays, video doorbells, portable DVDs, LCD TVs, and environmental protection equipment. They can adapt to wide temperature ranges, harsh environments, and prolonged high-load operation, depending on the requirements!
