Abstract

The invention discloses a behavioral risk assessment method and a home security care system; the method comprises the steps of constructing a convolutional neural network model, selecting a target type to be identified and identifying and positioning, wherein the target type to be identified comprises a danger object and a nursing object category; obtaining the position coordinates of each category in the target type, predicting the movement track of the moving care object, obtaining the angle between the moving direction of the care object and the connection direction of the care object and the danger object, and recording it as [theta], recording the distance between the care object and the danger object as d; constructing a risk assessment model to calculate the behavioral risk in realtime based on the relative position information d of the care object and the danger object ,and the predicted moving direction [theta]; and setting a safety threshold, so that it will flag an alarm when the risk exceeds the safety threshold. By the behavioral risk assessment method and the home security care system the caregiver can timely care for 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...
