Problems solved by technology

The microprocessor in the autopilot does not directly obtain sensor signals, and the microprocessor 10 itself does not contain an attitude calculation algorithm, so that multi-sensor data cannot be fused and optimally used
Moreover, some attitude acquisition devices 11 cannot obtain the full attitude information of the aircraft, and the processor 10 can only use part of the attitude angle to carry out flight control. Be applicable

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] As shown in FIG. 2 , the autopilot of the present invention includes two microprocessors: a first microprocessor 21 and a second microprocessor 22 . In the present invention, the first microprocessor 21 and the second microprocessor 22 share the functions of the microprocessor 10 in FIG. 1 . Wherein the first microprocessor 21 is mainly responsible for the function of aircraft flight control calculation, and the second microprocessor 22 is mainly responsible for the function of calculating the flight attitude of the aircraft. In this way, two microprocessors can perform parallel calculations to improve the data processing speed and control response speed of the autopilot.

[0026] In FIG. 2 , the attitude sensor group 23 includes several sensors for measuring the flight attitude of the aircraft. According to some different at...

Abstract

This invention discloses one automatic driving meter applied in aviator, which comprises first and second microprocessors, several sensors position sensor group, GPS receiver, gas sensor, upper and down communication interfaces. The first microprocessor has aviator control module and the second microprocessor has position computation module to compute aviator position information. The second microprocessor is connected to the first microprocessor through inner data bus in driver room. Outer circuit to convert into digital signals through second A / D converter to the second microprocessor processes the position sensor group measurement signals.

Description

technical field [0001] The invention relates to the field of aviation technology, more specifically, the invention relates to an autopilot applied to a micro-aircraft or a micro-unmanned aerial vehicle. Background technique [0002] The autopilot is the basic component and core device of the aircraft's automatic flight control and navigation system. It can assist or completely replace the driver's functions, and autonomously control the flight of the aircraft with little human intervention. Autopilots are widely used in modern aircraft, especially micro air vehicles or micro drones. [0003] An autopilot in the prior art is generally shown in FIG. 1 . The core device of the circuit is a microprocessor 10, which is responsible for processing various input information, and at the same time outputs the processing results to various peripheral interfaces to drive the peripherals to work, thereby realizing the automatic driving of the aircraft. [0004] The autopilot shown in F...
