Embodiment Construction
[0050] The present invention will be further described below in conjunction with accompanying drawing:
[0051] refer to figure 1 , is a schematic structural diagram of a digital air data computer of the present invention. refer to figure 2 , is a schematic structural diagram of the data processing circuit of the present invention. A digital air data computer of the present invention includes a pitot tube, which is also called a pitot tube. In the present invention, the pitot tube is used to measure the total pressure of the atmosphere and the static pressure of the atmosphere. A total pressure tube and a static pressure tube are arranged on the pitot tube, a first digital air pressure sensor is arranged at the outlet of the total pressure tube, and a second digital air pressure sensor is arranged at the outlet of the static pressure tube. In this way, the real-time signal (digital signal) of the total atmospheric pressure can be collected through the combined use of the p...

Abstract
The invention belongs to the technical field of aviation atmosphere data detection and discloses a digital atmosphere data computer and an implementation method thereof. The digital atmosphere data computer comprises a pitot tube and a temperature sensor, and a total pressure tube and a static pressure tube are arranged on the pitot tube. A first digital barometric sensor is arranged at an outlet of the total pressure tube, and a second digital barometric sensor is arranged at an outlet of the static pressure tube. The digital atmosphere data computer further comprises an operation amplifier, an analog-digital converter and a signal processing circuit, the input end of the operation amplifier is electrically connected with the signal output end of the temperature sensor, and the output end of the operation amplifier is electrically connected with the input end of the analog-digital converter. The signal processing circuit comprises an FPGA chip and a DSP chip, the input end of the FPGA chip is electrically connected with the first digital barometric sensor, the second digital barometric sensor and the analog-digital converter, and the FPGA chip is electrically connected with the DSP chip.
Description
technical field [0001] The invention belongs to the technical field of aviation air data detection, and in particular relates to a digital air data computer and an implementation method thereof. Background technique [0002] Air Data Computer (ADC) is a multi-input and multi-output airborne comprehensive measurement system, also known as air data center instrument. It calculates more parameters related to atmospheric data based on a small amount of raw information measured by sensors, such as static pressure, total pressure, total temperature, angle of attack, etc., such as flight altitude, altitude deviation, ascending and descending speed, true airspeed, indication Airspeed, Mach number, Mach number change rate, total temperature, real static pressure, atmospheric static temperature, atmospheric density ratio, real angle of attack, etc., and then send the calculated parameters to the cockpit display system, flight control system, navigation system, Engine control system, ...
