Abstract
According to the characteristics of too many types of plane parameter, increasing parameters needing to be collection, complex system and diverse requirements of aircraft flight data acquisition, a configurable aircraft data acquisition system based on FPGA + CPU was designed. This system architecture can give full play to the parallel working ability of FPGA in which to collecting multi-type and multichannel flight data simultaneously. At the same time, the sequential function of CPU is used to realize system configuration loading conveniently and complete flight data acquisition tasks without complex operation of professional technicians on the plane. This system has the advantages of simple circuit structure, high integration and high universal, which can be used for engine sensor parameter, air frame sensor parameter, flight attitude and other flight data.
