PXI platform-based fault injection system design for BIT validation

With the degree of integration and complexity of the modern weapon system rising and in order to improve the operational efficiency of the weapon system effectively and meet the modern weapons of the war for the convenience, accuracy and economy. The PHM(Prognostics & Health Management) technology adapted by many researchers. The BIT technology, as an important basis of PHM, has been studied widely: Comprehensive application and the validation and estimation of BIT have become new research focuses. Verifying the performance of BIT(built-in test) through fault-injection is an effective method to validate its testing ability. This paper focused on the PXI platform-based fault injection system design for BIT validation. With a certain type of MMC(mission computer) for the study, we carried out the product testability validation experiment under the laboratory conditions. On the basis of the design and performance of hardware/software, the experiment of BIT validation of MMC had been processed. Several typical faults were injected into the tested circuit of MMC in order to verify the testability of BIT. The result of the experiment shows that the fault injection system can fulfill the requirements of verifying the BIT performance.
