Abstract

The invention discloses a multi-rotor craft emergency protection system. The system comprises a parachute device, a safety control board, a power control board and a ground remote control unit. The parachute device, the safety control board and the power control board are all installed on a craft body. The parachute device and the power control board are both connected with the safety control board. The safety control board and a flight control module are in communication with the ground remote control unit in a wireless manner. The parachute device comprises a parachute and a jet device. The jet device contains high-pressure gas. A jet exhaust of the jet device is located below the parachute. The safety control board is connected with the jet device and controls the high-pressure gas jetted from the jet device to blow the parachute out. Emergency protection measures are additionally arranged on an existing multi-rotor craft, an air crash accident is effectively avoided, safety is high, the probability of self-crash and mistaken surrounding object damage of the craft can be reduced, and the overall safety and reliability are improved.

Description

Technical field [0001] The invention relates to the field of multi-rotor aircraft, and more specifically, to an emergency protection system for multi-rotor aircraft and an emergency protection method for the emergency protection system. Background technique [0002] Multi-rotor aircraft is a new type of unmanned aerial vehicle that has developed rapidly in recent years. It has the characteristics of small size, light weight, and low price. It can carry a certain weight of equipment to complete disaster monitoring, terrain detection, radio monitoring and forest fire cruise warning. But in practical applications, there are often operating errors and hardware and software failures. [0003] The structure of the existing multi-rotor aircraft includes an aircraft body, a flight control module, a navigation module, a motor and a power supply. The flight control module, navigation module, motor and power supply are all installed on the body. The flight control module is connected to the n...
