UAV minimum speed automatic protection control system

Abstract

The invention relates to a minimum speed protection control system for unmanned aerial vehicles, comprising: a control computer as a control center and an airspeed sensor electrically connected to it, the computer is equipped with two minimum speed fault handling modules that are started by timing interruption, and the two The modules include: a minimum speed over-boundary control module and a minimum speed fault handling control module, wherein the minimum speed over-boundary control module is used to monitor the aircraft speed obtained by the airspeed sensor system in real time, and control the speed of the aircraft within the allowable range; the minimum speed The fault handling control module is triggered by a clock timing interrupt, and its minimum fault handler controls the parachute recovery of the aircraft. According to the current flight speed obtained by the airspeed sensor, when the speed is lower than the minimum speed limit, the invention can adjust the throttle opening of the engine to resume normal flight, and can control the parachute recovery of the aircraft when the minimum speed cannot be controlled, which solves the problem Some UAVs do not have the minimum flight speed control and are prone to stall and cause flight accidents.

Description

UAV minimum speed automatic protection control system technical field [0001] The present invention relates to an automatic protection and control system for flying speed of unmanned aerial vehicles. Background technique In the prior art, the unmanned aircraft carrying out the air-to-air combat mission beyond visual range is different from manned aircraft The disadvantage is that the UAV is small in size, the onboard system is complex, the loading space, the capacity of the control computer, and the calculation speed are limited. The control system is simple, and the sensors carried by itself are few. Prior art unmanned aerial vehicles are due to the limitation of cost, aircraft loading space and load. system, it is impossible to fully install high-precision sensors. The flight control ability is weak, the autonomous control ability is poor, and the failure itself It cannot be ruled out that crash accidents are prone to occur. It requires the ground control center to...
