| description | The invention discloses an apparatus for measuring the height of an aircraft, and a method thereof. The apparatus includes a baroceptor, an instrument amplifier, a digital-to-analog conversion circuit, a filter circuit, a microprocessor and a power module; instrument amplifier is connected to the output end of the baroceptor, the filter circuit is connected to the output end of the baroceptor, and the baroceptor acquires change information of the pressure with the height and outputs a first voltage; the first voltage is amplified by the instrument amplifier, the amplified first voltage is filtered by the filter circuit, and the filtered amplified first voltage is output; the digital-to-analog conversion circuit converts a digital voltage value corresponding to the current pressure plane height of the aircraft to a reference voltage; the instrument amplifier amplifies a difference between the first voltage and the reference voltage and then outputs a second voltage; and the microprocessor processes the filtere |
