With the rapid development of computer technology and its wide application in the military field, the requirements for information security are increasing day by day. The motherboard, CPU and operating system of military computers have been controlled by foreign companies for a long time, which has brought serious security risks. In line with the basic principle of "solving information security issues starting from the terminal platform", in order to realize the independent controllability of military computers, the core software and hardware of military computers must be localized.

Most of the current mainstream hardened computers use the CPCI bus, which brings many restrictions on connection reliability, bus bandwidth and transmission rate, and cannot meet the increasing functional and performance requirements of military computers. CPCI-E is a serial bus, first of all, the bandwidth and transmission rate are greatly improved, and secondly, through the hierarchical reinforcement measures of the board and the whole machine, it completely solves the problem of unreliable connection on the CPCI bus, stability and reliability Sex greatly improved.

At present, mainstream hardened computers have relatively large lack of functions or unscientific features in terms of thermal management and platform hardware management. For example, intelligent speed regulation and fast maintenance and replacement of fans cannot be realized in harsh environments, and the working status of computer hardware cannot be displayed intuitively. and operational controls.

The current mainstream hardened computers are only designed according to the CPCI-E specification, with limited resources, weak functions, poor scalability, poor versatility, and no deep hardening. It's hard to find a CPCI-E ruggedized computer with broad-spectrum adaptability.
