Technology and switching device for ground function test of flight control system

Abstract

The invention discloses a technology and a switching device for ground function testing of a flight control system. Comprising a flight control system, the flight control system is electrically connected with an electronic equipment frame, the electronic equipment frame is electrically connected with an aircraft airfoil actuator, the flight control system and the aircraft airfoil actuator are respectively in communication connection with a signal transfer box, and the signal transfer box is electrically connected with an excitation / acquisition device; the signal transfer box comprises an analog signal processing circuit board, a discrete signal processing circuit board and a bus signal processing circuit board; according to the invention, multi-path collaborative test instruction sending and response signal acquisition can be realized, signal data between the flight control system and the flight control system actuator can be tested, the reliability of the flight control system and the actuator of the aircraft can be ensured, in-situ faults during ground function testing of the flight control system of the aircraft can be accurately positioned, and the reliability of the flight control system of the aircraft can be ensured. And the troubleshooting efficiency during the final assembly test of the flight control system is improved.

Description

technical field [0001] The invention belongs to the technical field of two-way information exchange, and in particular relates to a technology and a switching device for ground function testing of a flight control system. Background technique [0002] Before the final assembly of the aircraft, the flight control system needs to be tested on the ground in advance to ensure the functional integrity, and the final assembly test of the flight control system requires all related systems to be assembled and online before the final assembly test can be carried out. like figure 1 As shown in the figure, in the final assembly test of the flight control system, since the signals transmitted between the flight control system and the aircraft wing surface actuator are single-phase flow, it is impossible to collect and analyze the transmitted signals. If there is a fault in the test, the in-situ fault of the flight control system cannot be checked, and because the signal cannot be colle...

Problems solved by technology

like figure 1 As shown, in the final assembly test of the flight control system, since the signals transmitted between the flight control system and the aircraft wing actuators are single-phase flow, it is impossible to collect and analyze the transmitted signals

If a fault occurs during the test, the in-situ fault of the flight control system cannot be checked, and because the signal cannot be collected, it is impossible to analyze and judge the fault signal
