Research on Hardware Based Fault Diagnosis Model of Airborne Fuel Pump

Abstract

Fault diagnosis model for airborne products hardware model of transplantation difficult, the problem of low efficiency of hardware and software collaborative implementation, combined with airborne scenario performance requirements of the model, based on the hardware and software collaborative design and function module partition method, is proposed for the hardware of the onboard fuel pump fault diagnosis model and implementation method. Firstly, combined with the characteristics of hardware implementation of the model, a hardware-oriented fault diagnosis process for airborne fuel pump is designed. Secondly, the hardware and software modules of the airborne fuel pump fault diagnosis model are divided according to the data flow in the model, and the model is realized and optimized on FPGA by IP core and high-level synthesis (HLS) method, and the design and implementation of the airborne fuel pump fault diagnosis system is completed. The experimental results show that the proposed fault diagnosis model can improve the computational efficiency by 33.56 times compared with the common processor, which provides a solution for model transplantation and hardware realization and optimization in the hardware of fault diagnosis model for airborne components.
