This invention belongs to the field of
information security and relates to a
security monitoring device based on a VPX architecture. It includes: a main
processing module for
processing and computing
business data; a bridge module electrically connected to the main
processing module for expanding auxiliary peripherals; a management and control module electrically connected to both the main processing module and the bridge module for
system status monitoring and management; a
network communication module electrically connected to the bridge module for providing four
gigabit Ethernet interfaces to enable data interaction between systems; and a first level conversion module electrically connected to both the management and control module and the main processing module. This invention achieves end-to-end
autonomous control from computation and control to security, enabling the
perception and management of device health status, significantly improving fault diagnosis efficiency and
system maintainability. It can operate stably in harsh environments such as national defense and
aerospace, significantly improving
system reliability and lifespan.
