Design And Implementation Of Spacecraft Test Process Management System

Spacecraft test is the last link of checking before the spacecrafts leave the factory, and the testing works account for nearly half of the entire development cycle. Testing takes a long time, involving many units, with great changes of state, and it is difficult to adapt to the spacecraft test management requirements of multiple cabins and increasingly stronger functions through paper documents, meetings review and manual analysis. This paper mainly studies the design and application of spacecraft test process management system, mainly aimed to achieve informatization of spacecraft test process by designing and developing a set of complete system with testing of schedule management, and to improve spacecraft test coverage, integrity of plans, control during implementation of testing and closed-loop checks on the execution of result records.Spacecraft test process management system combines spacecraft-testing business and information technology, using highly information-oriented computer software processing systems, establishing scientific and standardized test schedule management processes to adapt mature spacecraft-testing division of labor and procedures. It uses Web server to achieve the rapid distribution of test data to thin clients, to complete data recording, reporting, approval process, to automatically complete closed-loop checks on plan generation and test results through internal logic, saving human input in management and analysis during test process, and to improve the quality of analysis and results sorting during testing process.The paper firstly discusses the conditions of spacecraft test process management system and existing business systems and conducts a thorough discussion on the basic framework and technological realization of office ideas that can meet higher demands. By discussing and analyzing existing office systems, it has proposed the feasibility and necessity of establishing and implementing spacecraft test process management system based on NET technology, presented a detailed implementation plan for NET-based spacecraft test process management system combined with the current actual needs of spacecraft test process management system and development requirements in the future, and mainly proposed and discussed the overall structure of the system, methods for hardware and software design and implementation and systems safety control, etc. At the same time, the paper has also expounded design class diagram and detailed implementation for each major functional block. Finally, the paper analyses the implementation of the proposed system on software testing as well as operating, and illuminates the effects after implementation of the system in details.
