The invention discloses a specific user identification and power consumption anomaly detection method based on multilevel power consumption characteristics, and belongs to the technical field of power electronic control. The method mainly comprises the following steps: optimizing a convolutional neural network according to historical power consumption data of a user in combination with a manual and multi-head attention mechanism to extract multi-level power consumption characteristics, and performing secondary weighting on final votes in a random forest by constructing a weighted decision tree and calculating importance similarity of the weighted decision tree and a random forest characteristic to form a weighted random forest algorithm. And finally, optimizing a weighted random forest through a particle swarm optimization algorithm to identify a specific user of the empty nest elderly, then detecting daily power consumption of the empty nest user according to an abnormal power consumption index, and carrying out telephone early warning on management personnel in a cell where the empty nest user with abnormal power consumption is located. According to the method, the empty nest users can be identified online according to the historical power consumption data, early warning can be performed in time when the power consumption is abnormal, the safety of the empty nest users is guaranteed from the perspective of power consumption, and the method has certain practical value.

The invention discloses a multi-agent-based space-time activity analysis and prediction method for urban empty nesters. Comprising the steps of collecting extrinsic features of community residents and constructing a space-time activity sand table, identifying urban empty-nest elderly people and staying points thereof, constructing a typical space-time activity chain of the urban empty-nest elderly people, constructing a multi-agent model of the urban empty-nest elderly people, simulating and screening demands of the empty-nest elderly people, and generating a public service facility layout optimization scheme. And the requirements of the empty nesters are visualized. According to the method, high-precision resident extrinsic features and high-resolution spatial data are acquired, and a multi-agent model is adopted to simulate and screen the demands of the empty-nest elderly, so that full-coverage, precise and multi-dimensional identification of the activity demands of the empty-nest elderly under an urban scale is realized; and a reliable basis is provided for perfecting urban community public service facilities and improving the life quality of old people.

The ladder stand device conforms to the human engineering principle, has the advantages of being simple in structure, convenient to implement, low in cost, safe and firm, reduces fear of owners, especially empty-nest old people during climbing, effectively avoids falling accidents possibly caused by weight-bearing climbing of overhauling workers, has monitoring and anti-theft functions, and is suitable for popularization and application. And good beneficial effects are achieved in the aspects of safety, practicability and convenience.

The utility model discloses an empty-nest elderly health monitoring equipment wearing device in the field of health monitoring, which comprises an arc-shaped shell and a watchband connected with one end of the arc-shaped shell, a limiting component connected with one side of the watchband, a locking component connected with one end, far away from the watchband, of the arc-shaped shell, and a display screen connected with the side surface of the arc-shaped shell. The side, away from the display screen, of the arc-shaped shell is connected with a butt joint component, and the side, away from the display screen, of the arc-shaped shell is connected with a butt joint component. The sensor modules are independent of the limiting structure of the device, so that the effect that the targeted sensor modules are selected according to different types of users to detect different physiological indexes of the users can be achieved; various functions of the device can be realized by replacing and installing different modularized sensor module structures.

This invention discloses an AI-based method for identifying and warning of abnormal behaviors in home-based elderly care, relating to the field of intelligent elderly care technology. It collects home activity data of elderly people from the past week, preprocesses the data, and then uses a density clustering algorithm to divide the preprocessed data into several home scenarios. Feature extraction and analysis are performed on the preprocessed data in these scenarios to obtain a scenario baseline dataset. A detailed analysis is then performed on the scenario baseline dataset, setting multi-layered threshold indicators for multiple features in each home scenario. The key technical points are: achieving comprehensive, accurate, personalized, and privacy-preserving identification of abnormal behaviors in home-based elderly care, providing 24 / 7, non-intrusive, and highly reliable security for elderly people living at home. It possesses high practicality and applicability, is adaptable to various home-based elderly care scenarios, and can be widely applied to home safety monitoring for elderly people living alone or in empty nests, showing promising application prospects.
