Abstract

The invention discloses a behavior risk assessment method and a family security care system, which constructs a convolutional neural network model, selects target types to be identified and performs identification and positioning, wherein the target types to be identified include dangerous objects and nursing objects category; after obtaining the position coordinates of each category in the target category, predict the trajectory of the moving care object, obtain the angle between the movement direction of the care object and the direction of the line connecting the care object and the dangerous object, and record it as θ, and the relationship between the care object and the dangerous object. The distance of the dangerous object is recorded as d; the risk assessment model is established, and the behavioral risk is calculated in real time according to the relative position information d of the nursing object and the dangerous object, and the predicted moving direction θ. And set the safety threshold, when the danger exceeds the safety threshold, a prompt alarm will be issued. The invention assists the caregiver to take timely care of the care object and avoid accidental injury.

Description

technical field [0001] The invention relates to the technical field of home security, in particular to a behavior risk assessment method and a home security care system. Background technique [0002] The family is a warm haven, but for some special groups, there are also many potential safety hazards. For example, young children have strong mobility and curiosity, and weak judgment on potential risk factors in the family environment, which often leads to accidental injuries; elderly people or those with dementia symptoms are less likely to be dangerous to the environment due to decline in physical functions and slow sensory actions. The ability to perceive is severely reduced, which is also prone to accidents. In the domestic environment, the main causes of injuries are mostly falling, sharp objects, burns, electric shocks, etc. And caregivers are often unable to take care of them all the time due to their limited energy. Therefore, the home security system that can intel...
