基于总线故障注入的卫星热控自主管理软件测试方案OA北大核心CSTPCD

In response to the new state in satellite thermal control subsystem design,the test re-quirements are summarized for multi-point temperature control function,tracking temperature control function and thermistor fault handling function in the thermal control autonomous ma-nagement software.A test scheme for satellite thermal control autonomous management soft-ware is also proposed based on bus fault injection.This scheme simulates bus telemetry by con-necting the fault injecting equipment into satellite data bus and verifies the correctness of the pro-cessing result of the thermal control autonomous management software.Compared with the existing test scheme based on thermistor equivalent devices,the proposed scheme can simplify the ground test equipment and cables while ensuring test effectiveness,and improve test efficien-cy.Test scheme step is given in the paper,which can provide a reference for the test of satellite autonomous management software.
