LED APPARATUS AND METHODS FOR EVALUATING DEGREE OF RISK OF LONELY DEATH USING DOOR OPENING SENSOR LED SYSTEM FOR EVALUATING DEGREE OF RISK OF LONELY DEATH

摘要

The present invention relates to an apparatus and method for evaluating the risk of lonely death using a door opening sensor, and to an LED system for evaluating the risk of lonely death. More particularly, the apparatus for evaluating lonely death risk using a door opening sensor according to an aspect of the present invention includes: The door open recognition unit that recognizes the opening, and the external activity, which is the time when the door is opened and the human body activity is not detected for a preset period of time from the time when the door is opened is recognized as an external activity state and is maintained in the external activity state An external activity time calculation unit that calculates the holding time, and when the human activity is detected again at the second time point, which has an idle detection period after the first time point, and the human body activity is detected at the first time point, it is determined as an internal activity state. , An internal activity time calculation unit that calculates the internal activity maintenance time, which is the time maintained in the internal activity state, and a probability distribution model based on the external activity maintenance time and internal activity maintenance time calculated in the first period, and the first It includes a risk assessment unit that evaluates the risk of lonely death by applying the maintenance time of external activities and the maintenance time of internal activities calculated after the period to the probability distribution model.
