Problems solved by technology

The new aircraft uses the internal module data bus of the flight control system and the actuator data bus of the flight control system to transmit communication data. The existing test technology cannot complete the link test of the above bus, so it is not suitable for the new aircraft fly-by-wire flight control system communication link test

Abstract

This application provides a bus test method and a device thereof. The bus test method comprises: receiving bus data in a bus link; inputting test data into the bus data to form new bus data; and transmitting the new bus data to the bus link. This bus test method is able to modify data in the bus link into test data so that a bus link test can be completed. The method is suitable for a communication link test of a new type aircraft fly-by-wire system.

Description

technical field [0001] The invention relates to the technical field of flight control system simulation testing, in particular to a bus testing method and device. Background technique [0002] The fly-by-wire flight control system is more and more widely used in the aircraft flight control system due to its high flexibility and stability. interface communication. [0003] In order to ensure the integrity of the aircraft flight control system performance, it is necessary to do various simulation tests on the communication link of the aircraft flight control system. During the simulation test process, it is necessary to replace part of the communication data with test data to meet the requirements of some tests. [0004] In the past aircraft flight control systems, analog signals or discrete signals were used to transmit data, usually using signal analyzers, oscilloscopes and signal generators to inject data into the communication link for testing. The new aircraft uses the ...
