Abstract： The command display system of computer system faces increasing challenges in terms of stability, reliability, and flexibility. This paper proposes a command display framework based on the Qt framework, integrating data processing, interface management, and multi-task support to meet the diverse needs of complex space missions. Additionally, a multi-process page interaction display technology based on continuous data protection is adopted, which combines the main process with independent page display processes, significantly enhancing the system's stability and security. Furthermore, this paper applies continuity situation display technology and improves the adaptive periodic time bucket algorithm, optimizing event synchronization and rollback mechanisms to further enhance the accuracy and efficiency of task replay. These technological improvements address the requirements of the next-generation command display system of the software system, providing strong support for the successful execution of complex space missions.
