Abstract

The invention relates to the technical field of power supply detection, and discloses a power supply detection circuit for an aircraft, which comprises two master control layers, the two master control layers are respectively a master control layer I and a master control layer II, the master control layer I and the master control layer II are connected in parallel, and two ends of the master control layer I and the master control layer II are connected with switches. The switch controls current loops of the first master control layer and the second master control layer, a power supply is connected between one end of the first master control layer and the switch and between one end of the second master control layer and the switch, the two ends of the switch are connected with a universal meter in parallel, the universal meter is a high-precision universal meter, the universal meter is further connected with a data acquisition instrument, and the data acquisition instrument is connected with the power supply. And the data acquisition instrument is used for recording the current tested by the universal meter. The power supply detection circuit, method and management system for the aircraft have the advantages of high test efficiency, low test difficulty, high precision and the like, and solve the problems that the circuit cannot be quickly connected, the test efficiency is low, the test difficulty is increased, and the test precision of the power supply is influenced.
