The smart airbag suit includes: an anti-impact suit body, a three-axis gyroscope sensor, a main control circuit board, a lithium battery, an inflator, a gas cylinder, and an airbag. The three-axis gyroscope sensor is assembled on the body of the anti-impact suit and is used to collect human body motion posture data information; the main control circuit board is electrically connected to the three-axis gyro sensor to receive and detect human body motion posture data information; the electrical inflator device Connect the main control circuit board; the gas cylinder is assembled on the anti-impact suit body; and the airbag is assembled in the anti-impact suit body, and the airbag is a spiral airbag; when the main control circuit board detects that the human body movement posture data information reaches the first preset value When the time, the main control circuit board triggers the inflator to open the gas cylinder to inflate the airbag. As a result, the smart airbag anti-impact suit does not require any fixed points and triggers the airbag after a fall, which can provide individuals with safer protection in time when danger occurs.
