Abstract:In order to ensure the integrity and correctness of launch vehicle test data, and overcome the shortcomings of low interpretation efficiency, easy misjudgment and missing judgment of traditional manual interpretation mode, and poor adaptability, expansibility and reusability of automatic interpretation mode of general programming language, a domain specific language IPL(Interpretation Language) in the field of launch vehicle test data interpretation and its supporting language parsing and actuator are proposed and designed, which realize the formal definition and description of launch vehicle test data interpretation criteria, reduce the learning and interpretation cost of business personnel, and make the massive test data interpretation complete automatically at the minute level. At present, it has been successfully applied in the engineering practice with multi type new generation launch vehicles.
