Let me introduce to you the difference between industrial computer motherboards and commercial motherboards:
1. Commercial motherboards use ordinary electrolytic capacitors, which is important to reduce the cost of motherboards
2. Industrial control motherboard components: The components of the motherboard must adapt to wide temperature conditions (-20°C~60°C), to ensure that they are in a poisonous environment (always on during the lifespan, poisonous weather, humidity, vibration, dust, radiation, high temperature) etc.) normal things; motherboard components must be resistant to high temperature, moisture and so on. High quality chip electrolytic, tantalum, ceramic capacitors
3. The PCB of the industrial control motherboard: the commercial motherboard adopts a 4-layer PCB design. The general PCB clear board has four layers. The upper and lower layers are the signal layer, and the two central layers are the ground layer and the power layer. and the power plane are placed in the center. The industrial motherboard adopts the PCB clear board plan with more than 6 layers. The plan is to strengthen the anti-electromagnetic interference and electromagnetic compatibility capabilities of the motherboard, strengthen the stability of the motherboard, etc.
4. CPU: The industrial control motherboard generally uses a low-power CPU, so as to adapt to the sinister situation of the industrial control industry and use AtomN230\270\330\N450D525. The integrated functions of the north and south bridges are integrated into the CPU on the processor
5. The ability to resist electromagnetic wave interference is different: the ability to resist electromagnetic wave interference is high, and it is necessary to go through EMI, EMC and other trials and certifications. This needs to be considered from two aspects, one is to consider the clear layout plan of the motherboard, and the other is to consider the material selection and layout, power supply, and grounding conditions
6. Support more interfaces: At the same time, it can support Mini PCI-E, PC 104+, multi-COM interface, embedded GPIO bus, dual-performance function with LVDS, HDMI, DVI interface, the whole field card can cooperate with the backplane to expand Support multiple ISA, PCI, MINIPCI expansion.
7. Application situation: The working temperature of industrial control motherboards often reaches -20 degrees to 70 degrees under insidious conditions (always on during the life cycle, insidious weather, humidity, vibration, dust, radiation, high temperature, etc.), and these conditions The next thing is that commercial motherboards are not up to the task.
8. Protection function: The industrial control motherboard of the industrial computer has undergone extra planning. In the event of a crash or other emergency, it can complete the functions such as automatic restart of the watchdog, anti-surge attack, etc., and strive to ensure the high stability of the system in the sinister environment. ask;
