1. The industrial computer supports more interfaces: at the same time, it can support Mini PCI-E, PC 104+, multi-COM interface, embedded GPIO bus, dual display function with LVDS, HDMI, DVI interface, the whole field card can cooperate with the bottom plate to make more Extensibility to support multiple ISA, PCI, MINIPCI expansion.
2. Use environment: The working temperature range of industrial control motherboards often can reach -20 degrees to 70 degrees in harsh environments (booting during life, harsh weather, humidity, vibration, dust, radiation, high temperature, etc.), and in these environments Commercial motherboards are not up to the task.
3. Protection function: Through special design, the industrial control motherboard can realize functions such as automatic restart of the watchdog and anti-surge shock when encountering abnormal situations such as crashes, so as to fully guarantee the high stability of the system in harsh environments.
4. Commercial motherboards use ordinary electrolytic capacitors, mainly to reduce the cost of the motherboard.
5. Industrial control motherboard components: The components of the motherboard need to adapt to a wide temperature environment (-20 ° C ~ 60 ° C) to ensure that they can be used in harsh environments (booting during life, harsh climate, humidity, vibration, dust, radiation, high temperature, etc. etc.) work normally; motherboard components need to be resistant to high temperature, moisture, etc. High quality chip electrolytic, tantalum, ceramic capacitors
6. The PCB of the industrial control motherboard: the commercial motherboard adopts a 4-layer PCB design. The general PCB circuit board has four layers. The top and bottom two layers are the signal layer, and the middle two layers are the ground layer and the power layer. and the power plane in the middle. The industrial motherboard adopts a PCB circuit board design of more than 6 layers, which is designed to strengthen the anti-electromagnetic interference, electromagnetic compatibility of the motherboard, and enhance the stability of the motherboard, etc.
7. CPU: The industrial control motherboard generally uses a low-power CPU to adapt to the harsh environment of the industrial control industry. AtomN230\270\330\N450D525. The CPU that integrates some functions of the north and south bridges on the processor
8. The anti-electromagnetic wave interference ability of industrial computer is different: the anti-electromagnetic wave interference ability has high requirements, and it needs to pass EMI, EMC and other tests and certifications. This needs to be considered from two aspects, one is to consider the circuit layout design of the motherboard, the other is to consider the material selection and structure, power supply, and grounding conditions
