Design of Manned Lunar Spacecraft Avionics System Structure
In view of the characteristics of data in the manned lunar exploration vehicle,such as varied kinds,large amount and far distribution,and the requirements for high reliability data communication,by investigating the development trends of avionics system in spacecraft at home and abroad and systematically analyzing the needs and technical characteristics of manned lunar exploration missions,adhering to the design concept of uniform network,current compute,composite execute and software APP,a new two-layer hierarchical control integrated electronic system architecture of"unified management-regional implementation"is proposed.The research objectives and implementation approaches of key technologies such as high performance computing,time-triggered network,highly integrated acquisition and driver,time-sharing and partition operating system are described in detail.Applied to the integrated electronic system design of manned lunar exploration vehicle,it will effectively improve the capability of autonomous health management and mission planning,functional density,design reliability and closed-loop control with human participation.
