Automatic parachute ejection special control circuit of multi-rotor-wing unmanned aerial vehicle

Abstract

The invention discloses an automatic parachute ejection special control circuit of a multi-rotor-wing unmanned aerial vehicle. The automatic parachute ejection special control circuit comprises a power supply, three chips including main control chips IC1, a gyroscope accelerometer IC2, a barometer IC3, five resistors including a resistor R1, a resistor R2, a resistor R3, a resistor R4 and a resistor R5, four capacitors including a capacitor C1, a capacitor C2, a capacitor C3 and a capacitor C4, two light-emitting diodes including a light-emitting diode LED1 and a light-emitting diode LED2, and three connectors including a connector J1, a connector J2 and a connector J3; the main control chips IC1 are connected with the gyroscope accelerometer IC2 through five SPI (Serial Peripheral Interface) signals 55, 56, 57, 58 and 59 of the chip; the main control chips IC1 are connected with the barometer IC3 through two I2C interface signals 42 and 43 of the chip. With the adoption of the automatic parachute ejection special control circuit, whether tilting of normal flight or rolling in a breakdown occurring process can be accurately judged, so that a parachute opening signal is output through the connector J1 and the connector J2 when a parachute is located at the upper side, and furthermore, the parachute is opened and the safety of the machine is protected.

Description

technical field [0001] The invention relates to the field of circuits, in particular to a special control circuit for automatic parachute ejection of a multi-rotor drone. Background technique [0002] With the gradual popularization of multi-rotor drones, when the airborne safety parachute of the drone is opened is also a key point in this technical field, but the control of the general parachute is still carried out by the flight controller of the drone. To control, when the flight controller fails, the parachute cannot be opened, which will cause the aircraft to fall from a high altitude and be damaged, or even injure people or things. When the aircraft has a problem, it is the flight control that is in a state of disorder and out of control, so the parachute is useless. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems existing in the prior art, and to provide a special control circuit for automatic parachute ejec...
