Whether it is an ordinary computer or an industrial computer, the core components are motherboards, and industrial motherboards have a wider range of applications and more complex use environments, so users have higher requirements for the functions, compatibility, and reliability of industrial motherboards. So what use needs does the industrial motherboard need to meet?
1. Demand for product design
Industrial motherboards need to work uninterrupted for a long time, requiring industrial motherboards to be specially designed in terms of resistance to high and low temperature, vibration, and electromagnetic interference. In addition, the selection of industrial motherboards requires long-term and high-demand verification components to ensure the high reliability requirements of industrial motherboards under complex conditions.
2. Dimensional requirements
Industrial motherboards need to adapt to different industrial scenes. Industrial computer manufacturers are required to provide industrial motherboards with different architectures, such as X86 architecture and ARM architecture. Industrial motherboards of different sizes include 2.5-inch, 3.5-inch, 5.25-inch, ATX, Micro-ATX, etc. Specifications; Highly integrated industrial motherboard to meet the requirements of the use environment and operating performance.
3. Functional requirements
(1) Extensive compatibility and stability tests must be completed before leaving the industrial motherboard, including aging tests, environmental compatibility tests, and software safety tests, to ensure that each industrial motherboard component can be used in a wide temperature, humidity, vibration, and dusty environment. Long-term trouble-free operation.
(2) I / O interface is abundant, can connect many kinds of equipment. Common interfaces of industrial motherboards include serial ports, USB, LAN, LVDS, etc., and expansion slots include PCI, PCIE, Mini PCIE, etc., which are highly scalable. At the same time with a variety of display interfaces, such as VGA, HDMI, DP, DVI, LPT and so on.
(3) In addition to providing remote connection management functions, the industrial motherboard can also realize remote unattended automatic switching on and off. In case of abnormal conditions such as downtime, it can automatically restart to ensure the high stability requirements of industrial control computers.
4. Other needs
Industrial motherboards are required to work between -40 ° C and 80 ° C. Industrial computer manufacturers are required to carry out special designs and treatments on the thermal insulation of industrial motherboards, such as installing all-aluminum housings and high-power fans on industrial motherboards. CPU, North-South Bridge and hard disk and other heat-generating components are specially treated to ensure continuous normal operation under the high-temperature conditions of industrial computers. In addition, according to the requirements of the use environment, more and more industrial motherboards adopt fanless design, which has low power consumption and low heat generation, which improves the cooling efficiency and reduces the failure rate of industrial control machines.
