| Abstract: | This paper achieved the conversion between USB protocol data packets and data packets of the 429 data bus protocol on the basis of the ARINC429 specification and USB message protocol. According to the electrical characteristics between the 429 data bus and USB interface, we proposed the realization method of the 429 data bus and USB interface of a kind of low cost conversion hardware, using USB bus to complete data communication in multi ARINC429 bus device at the same time. This loader was convenient for the data communication between ARINC429 bus and PC machine and effectively reduced the cost of aviation equipment data update. |
