Abstract

The invention discloses a test verification system applied to satellite CPU software on-orbit reconstruction. The test verification system comprises a reconfigurable verification code automatic generation system module, a tested part simulation operation system module, a reconstruction full-real-time automatic monitoring system module and a reconstruction fault injection system module, wherein thereconfigurable verification code automatic generation system module provides reconstruction data for test verification of reconstruction, and compiles and generates a target code for tested software;the tested part simulation operation system module provides a simulation system for simulating a real running environment for the tested software with a reconstructed design; the reconstruction full-real-time automatic monitoring system module is used for carrying out real-time monitoring on the whole reconstruction process; the reconstruction fault injection system module provides various typesof fault injection for test verification of satellite CPU software reconstruction, and can achieve fault injection at each stage of a CPU reconfiguration design strategy verification target point of the satellite software.

Description

technical field [0001] The invention relates to the field of computer software verification and testing, in particular to the module composition, module structure and functions of a platform system capable of performing ground multi-type fault injection test verification on the on-orbit reconfiguration process and results of satellite CPU software. Background technique [0002] Satellite operation requires the coordinated work of a large number of satellite CPU software. These software cooperate with each other to ensure the normal operation and mission execution of the satellite. When a satellite is in orbit, its CPU software often runs abnormally due to unexpected circumstances. At this time, the ground will inject updated software codes on the malfunctioning CPU software of the satellite through the measurement and control system to replace the codes of the malfunctioning CPU software. In addition, due to the needs of mission adjustment, the ground updates the software ...
