Embodiment
[0098] The embedded software reliability acceleration test method provided by the present invention is used to perform software reliability acceleration test on the real-time control software of an inertial navigation system (hereinafter referred to as INS). The main functions of the INS include navigation calculation, process control, fault handling and so on. The INS software exchanges data with 11 avionics systems such as DCMP, DTE, FCS, MC, CADC, etc. through the 1553B bus, and guarantees process control and fault handling through real-time transmission of control command data between devices. The specific test process is as follows:
[0099] The first step is the establishment of the software mission profile.
[0100] According to the software task profile generation method proposed in the present invention, the software requirements specification is first analyzed, the function set of the software is clarified, and the software task set (that is, the INS all The set of tasks)...
