Abstract

In this paper, an interface circuit based on aircraft consumption sensor is proposed. Sinusoidal AC excitation signal with a peak value of 10V± 20% to the ground and a frequency of 4000HZ±10HZ is applied to the consumption sensor, and the excitation signal is monitored. At the same time, the envelope signal with a maximum amplitude of 1.2-1.3V output by the consumption sensor is collected. The envelope number is demodulated by diode detection circuit, proportional amplifier circuit and hysteresis comparator circuit, so as to realize the monitoring of aircraft engine fuel consumption. The pilot can manage aircraft fuel according to the consumption. The method has been verified by practical engineering.
