Test case simulation and verification method and device for spacecraft test identification

Abstract

The invention discloses a test case simulation and verification method and device for spacecraft test identification. The problem that verification and evaluation of safety and completeness of a spacecraft test identification case completely depend on a manual mode can be solved. The method comprises the following steps: establishing a rule model corresponding to a telemetering and remote control function of a spacecraft test identification item; remote control instructions and telemetering data of historical spacecraft test identification items in the time interval are acquired, and a data model is established; combining the rule model and the data model with the same attribute label to form an input and output closed-loop simulation verification model; and comparing the remote control instruction code historical record recorded in the data model with the remote control instruction codes input by the rule model, and when the remote control instruction codes are consistent and matched with the sequential relationship, converting the telemetering data output by the data model into corresponding telemetering parameters under the rule model by using a telemetering and remote control protocol conversion interface, and a round of simulation from excitation to feedback is completed.

Description

technical field [0001] The invention relates to the field of spacecraft test appraisal and computer simulation, in particular to a method and device for test case simulation and verification oriented to spacecraft test appraisal. Background technique [0002] There are many types of spacecraft systems, with large differences in operating modes and states. During the entire life cycle, the operating environment, testing, and testing processes vary greatly with different development and use stages and application tasks, resulting in development and testing, experimental training, maintenance support, and other processes. The phases are separated from each other, the state inheritance is poor, and the design of test cases is repeated. During the test and experiment process of space-based systems, the verification of complex logic functions within sub-systems and between multiple systems is gradually changing to automated test sequence verification. At present, it is impossible ...
