The existing popular technology is to adopt a VPX bus as a transmission bus of the ruggedized computer, and compared with the traditional high-performance real-time industrial buses such as VME, VXI, PXI, CPCI and the like, the VPX bus supports various communication architectures and high-speed serial bus protocols such as PCI Express, rapidIO, 1G/10GEthernet and the like, so that the system transmission bandwidth is greatly improved. However, the improvement of the bus technology of the ruggedized computer system does not leave the support of the motherboard, and the computing performance of the motherboard is still an important index for ruggedized computers, so the ruggedized computer motherboard adopting the VPX bus is the key point of design.

The problem has been solved to a great extent to the design of consolidating the computer mainboard based on COME module, through COME modular form, has reduced research and development risk and development technical difficulty, can dispose in a flexible way in multiple different demands through changing the support plate, satisfies the application demand.

However, most of the designs of the main board of the ruggedized computer based on the COME module adopt foreign chips such as Intel chips, and the problems can be fundamentally solved by adopting domestic devices for the design of the main board of the ruggedized computer due to the fact that the current international situation is increasingly complex and changeable, the instability of the external environment is increasingly enhanced, and the supply chain of electronic components faces severe challenges.
