| Abstract: | In order to meet the wide demand of ARINC429 in avionics field,an improved ARINC429 bus transceiver system was designed; Firstly,it introduced the ARINC429 bus characteristics briefly,and the digital information transmission strictly executes the ARINC429 specification and adopts universal ARINC429 special components HS-3282 and HS-3182 as to a data transceiver core unit in the system.Then,the hardware design and software process of this system based on DSP and FPGA were given.And the entire system is controlled by DSP and the system logical design is achieved by programming FPGA.The results of the experiment show that the interface of ARINC429 based on DSP and FPGA can meet the demand of data communications with good reliability,accuracy transmission and high integration.It can be widely used in the field of avionics communications. |
