This paper focuses on China’s first asteroid exploration mission. In accordance with the single-unit functional requirements of the payload management unit for the Tianwen-2 probe, it introduces the unit’s composition design, operating modes, and single-unit functions. This device ensures the power supply and distribution safety of the subsystem through designs such as power fault isolation. It enhances the system’s fault tolerance capability by means of on-orbit updatable and customizable status monitoring, fault recovery processing, and other measures. Relying on autonomous detection, it achieves precise mission switching and autonomous mission planning. Moreover, through data management designs like joint detection and scientific data preprocessing, it improves the efficiency of scientific detection. Ultimately, it enhances the reliability of the payload system, realizes integration, autonomy, and high efficiency, and lays a technical foundation for the design of payload systems in China’s subsequent deep-space exploration missions.
Key words: Tianwen-2; payload management unit; overall design
