Unmanned plane flight control computer design method

Abstract

The invention discloses an unmanned plane flight control computer design method, and comprises the following steps: 1, designing a microprocessor; 2, designing an analog quantity signal conditioning module, and using an adder to make translations and an operation amplifier to attenuate; 3, designing a digital quantity input / output module; 4, designing a DA output module, and using a 12-bit DA conversion chip DAC7718 to complete digital quantity and analog quantity transformations; 5, designing a serial communication expansion module, and employing a SP3232 and MAX 3490 chip to carry out full duplex serial interface transitions; 6, mounting a strap-down heading and attitude system module, an air pressure alleviator module and a ferroelectric memory extensive module on a communication module. The unmanned plane flight control computer design method can realize expansion from a core controller to various basic modules; the hardware design by the design method is simple and reliable, and the designed hardware is small in size, light in weight, and high in endurance ability.

Description

technical field [0001] The invention relates to a computer hardware design method, in particular to a computer hardware method for unmanned aerial vehicle flight control, which belongs to the field of computer technology. Background technique [0002] With the continuous development and maturity of computer technology, modern military development and the needs of war, UAVs are developing rapidly. The flight control system is an important part of UAVs, and the flight control computer is the carrier for the flight control system software to run. Existing UAVs are relatively large in size, heavy in weight, and have complex operating mechanisms, which also impose certain restrictions on their application environments. At the same time, their heavy weight causes their battery life to be greatly reduced. Under normal circumstances, the design of the flight control computer of the UAV should be small in size, easy to install in the control cabin of the UAV, light in weight as much ...
