Research And Realization Of Power Monitor System On Multiple Electric Aircraft Based On Qt

Modern aircraft is mainly possessing three forms of secondary energy, including hydraulic,pneumatic and electrical energy. The unifying of these secondary energy using on aircraft, in otherword, the development of all-electric and aircraft using multiple electric, helps improving thereliability, maintenance, ground support for aircraft performance and viability, while reducing theweight of the aircraft.Automatically multiple power supply switching and distribution power technology on aircraft isan essential part of modern aircraft power supply system. A real-time and effective monitoring is acritical work in automatically multiple power supply switching and distribution power technology.Only in the guarantee of each power supply be stable and reliable, can effectively switching inmultiple power.This article describes the type of power and technical requirements of the aircraft using multipleelectric, analyzes the monitoring methods of voltage and current, discusses the principle andtransplant method of embedded Linux system, while researches the Qt graphical interface designmethod. Ultimately, this paper designs a power monitoring system of aircraft using multiple electricbased on ARM9chip, which using DC28V as a model for real-time monitoring of the output voltageand electric current, indicating the various operating status of the power supply. This kind of systemwill take alarm and deal with problems when abnormal situation happens. In software, based on theembedded Linux operating system, according to Qt-based graphical interface development, it providesto users with a good man-machine interface, and the convenience for real-time query and access.
