Abstract

The invention provides a data acquisition method and relates to the aeronautical communication technology. The data acquisition method realizes the AFDX protocol device test. The data acquisition method comprises the following steps: monitoring all network ports used for sending and receiving data and conforming to the ARINC664 protocol standard; sampling the sent or received data when the condition that data is sent or received by any one of the network ports is monitored. The data acquisition method adopting the technical scheme is applicable to AFDX, and the AFDX protocol device test is realized.

Description

technical field [0001] The invention relates to aviation communication technology, in particular to a data collection method in the AFDX protocol. Background technique [0002] AFDX (Avionics Full Duplex Switched Ethernet, avionics full-duplex real-time Ethernet) is a technology implemented by Airbus for certain aircraft data networks (Aircraft Data Networks) according to the ARINC664 specification. At present, it has been widely used to interconnect electronic systems in aviation vehicles, such as engines, flight control components, cruise systems, etc. To date, AFDX has been used in the A380, A400M and Boeing B787 programs. Therefore, the test of the equipment based on the AFDX protocol must be very complete, and at the same time, high requirements are put forward for the rapid collection of data during the test. Contents of the invention [0003] The invention provides a data collection method and solves the problem of AFDX protocol equipment testing. [0004] A data...
