Research and realization of digital export boards in CPCI test system based on high availability hot-swap technology

CPCI bus, as many buses more complex, aerospace test system the most widely used bus system, is ranging from high-grade hot swap technology and hot backup technology to achieve greater application needs. Its design, application methods and techniques applied in the transformation to meet the related equipment upgrades, but also instructive in higher levels of overall system design process. Especially important guiding significance for thermal measurement and control system design and overall system redundancy hot backup plan structure. Therefore, CPCI bus, hot-swappable and hot backup technology achieve the most representative. This issue is chosen the most representative system design example, according to the relevant standard design demonstration experiment platform, design the HILS system and Control System validate the hot redundancy of the system. On this basis the relevant technical report to verify the proposed theory is correct.
