Problems solved by technology

[0005] In the ground inspection of the traditional aircraft power supply and distribution system, in order to verify the system logic under abnormal working conditions, it is usually only possible to disconnect some lines on the aircraft, and then measure one or some working status information independently. The overall working status of the power distribution system is used to judge whether it meets the design requirements, which will lead to some hidden faults not being discovered in time; moreover, the ground detection of the traditional aircraft power supply and distribution system requires the operator to manually perform repeated operations on the aircraft many times, which is costly A lot of manpower and time

Embodiment Construction

[0012] Referring to the accompanying drawings, the aircraft power supply and distribution ground detection crime framework proposed by this application is shown in figure 1 , in which the aircraft power supply and distribution system is the on-board system, and the rest are the framework of the detection simulator. The generator simulator in the detection simulator may be a plurality of generator simulators connected in parallel, respectively simulating multiple alternators on the aircraft. The generator simulator in the embodiment includes the left alternator simulator corresponding to the left alternator of the aircraft power supply and distribution system, the right alternator simulator corresponding to the right alternator of the aircraft power supply and distribution system, and the corresponding aircraft power supply and distribution system. The auxiliary alternator simulator of the auxiliary alternator of the electrical system and the emergency alternator simulator corr...

Abstract

An aircraft power supply and distribution system ground detection method adopts a detection simulator, and the detection simulator comprises a generator simulator, a storage battery simulator, a transformer rectifier simulator, a signal acquisition processor and a display control terminal. The detection simulator simulates the power generation system of the airplane, and performs signal acquisition, state display and fault judgment on the working state of the power supply and distribution system of the airplane, so that logic verification on the power supply and distribution system of the airplane in normal and abnormal working states can be implemented on the ground.

Description

technical field [0001] The application belongs to aircraft design technology, relates to the technical field of aircraft power supply and distribution system testing, and specifically relates to a ground monitoring method for an aircraft power supply and distribution system. Background technique [0002] With the popularization of full fly-by-wire control in the civil aviation industry, in the power system transmission of aircraft, it has more and more replaced the transmission of secondary energy such as machinery and hydraulics, ensuring the normal operation and stable operation of the power system is all-electric The core of transmission control. [0003] The aircraft power supply and distribution system is an important part of the aircraft power system, responsible for providing AC and DC power for various systems on the aircraft. The aircraft power supply and distribution system is usually composed of bus bars, contactors, circuit breakers, fuses, and power controllers...
