Portable airplane power supply quality test system and method

Abstract

The invention discloses a portable airplane power supply quality test system. The portable airplane power supply quality test system comprises a host, an alligator clip, a current sensor, a peripheral device and a matched cable. The host comprises a PC104 computer, a multichannel synchronous acquisition card, a voltage regulation circuit board, a display, a switching power supply, a current detecting interface, a voltage detecting interface, a current input interface, a voltage input interface, a solid state disk and a fan. The portable airplane power supply quality test system has the advantages of being high in reliability and being able to overcome the unfavorable environmental factors that the outfield temperature of the airplane changes violently and the vibratility is high. The portable airplane power supply quality test system and method can realize on-line detection of power supply quality and waveform recording at the same time, and have dual function for a traditional instrument and a waveform recorder. Besides, the waveform data playback can be directly completed in the airplane without exporting the data so that the portable airplane power supply quality test system and method are convenient to use.

Description

Technical field [0001] The invention relates to an aircraft power supply quality testing system and method. Background technique [0002] The aircraft power system is an important platform system of the aircraft. It is responsible for providing AC and DC power that meets the requirements for the electrical equipment of the entire aircraft. In order to ensure the coordination of power supply and electrical equipment, the aircraft design must strictly follow the requirements of GJB181A aircraft power supply characteristics. Aircraft power and electrical equipment. As the use time increases, the power supply characteristics of the aircraft will change. In order to detect this hidden danger in time, it is necessary to check the power supply characteristics of the aircraft. Due to the many power supply parameters stipulated by the National Military Standards, traditional instrumentation cannot be implemented, and computer measurement and control methods must be used to achieve it.

Problems solved by technology

The cost of high-speed waveform recorder is relatively high, and the waveform recorder is of general design, not designed for the characteristics of aircraft power supply. On the other hand, it needs to be used with a computer, and the work efficiency is low

The hand-held power supply quality tester generally tests the power frequency 50Hz AC, which cannot meet the requirements of the aircraft intermediate frequency 400Hz AC. Moreover, even if it meets the test technical requirements for 400Hz AC, the relevant power supply quality parameters are not in accordance with the national military standard. Computational, limited flexibility of use
