Fall protection intelligent alarm method based on millimeter wave radar

The invention relates to the technical field of millimeter-wave radars, in particular to a falling protection intelligent alarm method based on millimeter-wave radars, and the method comprises the steps: obtaining the motion parameters and environment data of passengers in a subway station through the millimeter-wave radars, including the motion speed, acceleration, direction and track, and the environment information of people flow density, humidity, temperature and the like; thirdly, through historical data analysis and behavior pattern recognition, the behavior pattern of the passenger is compared with a safety behavior pattern, and an abnormal behavior is judged; furthermore, falling risk parameters are predicted in combination with abnormal behaviors and historical data, the influence of environmental factors on falling risks is analyzed, a falling risk score is calculated, a risk level is determined according to the score, and a corresponding alarm strategy is implemented.
