Research and application of cargo hold management control technology in civil aviation cargo loading system

Cargo hold management and control technology is one of the core technologies of civil air cargo system, which plays an important role in the advancement, availability and ease of operation of the system. In this paper, we study the key technologies of power drive unit (PDU) position coding and high mission reliability drive control based on the architecture of belly cargo system of large wide-body aircraft, and verify the principle. The technology fills the technical gap of domestic containerized cargo system in the field of cargo hold management and control, and provides theoretical basis and technical support for the research and development of the containerized cargo system in the belly cabin of large wide -body aircraft and the main cabin of large cargo aircraft.
