Whether it is an ordinary computer or an industrial computer, the core components are motherboards, and the industrial motherboards have wider application scope and more complicated use environments, so users have higher requirements for functions, compatibility, and reliability of industrial motherboards. What are the needs of the industrial motherboard?
1. Product design requirements
Industrial motherboards require long-term uninterrupted work, requiring industrial motherboards to be specially designed for high and low temperature resistance, vibration resistance, and electromagnetic interference resistance. In addition, the industrial motherboard selection requires long-term, high-demand verification of components to ensure high reliability requirements of industrial motherboards under complex conditions.
2, the size of the requirements
Industrial motherboards need to adapt to different industrial sites, requiring industrial computer manufacturers to provide industrial motherboards with different architectures, such as X86 architecture and ARM architecture; industrial motherboards of different sizes, including 2.5-inch, 3.5-inch, 5.25-inch, ATX, Micro-ATX, etc. Specifications; high-integration industrial motherboards to meet the needs of the environment and operational performance.
3, functional requirements
(1) Industrial motherboards must complete extensive compatibility and stability testing before leaving the factory, including aging test, environmental compatibility test, and software safety test to ensure that each industrial motherboard component can be in a wide temperature, humidity, vibration, dusty environment, etc. Long-term trouble-free operation.
(2) The I/O interface is rich and can be connected to a variety of devices. Common interfaces of industrial motherboards include serial port, USB, LAN, LVDS, etc. The 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, industrial motherboards can also realize remote unattended automatic on/off function. In case of abnormal conditions such as downtime, automatic restart can be realized to ensure high stability requirements of industrial computer.
4, other needs
Industrial motherboards can work between -40 ° C and 80 ° C, requiring industrial computer manufacturers to carry out special design and processing on the thermal insulation of industrial motherboards, such as installing all-aluminum housings, high-power fans, etc. for industrial motherboards, The heat-generating components such as the CPU, the North-South Bridge, and the hard disk are specially treated to ensure continuous operation under the high temperature conditions of the industrial computer. In addition, according to the needs of the use environment, more and more industrial motherboards adopt fanless design, low power consumption and low heat generation, which reduces the failure rate of the industrial computer while improving the heat dissipation efficiency.
