Embodiment Construction

[0056] In order to make the features and advantages of this patent more obvious and easy to understand, the following special examples are described in detail as follows:

[0057] figure 1 It is a schematic flow chart of the method for analyzing abnormal changes in electricity consumption of the lonely and widowed elderly in different levels and time levels according to the embodiment of the present invention. The steps referring to this figure are as follows:

[0058] 1. Preprocess the collected electricity consumption data of widowed and lonely elderly users, fill in the missing data, and set reasonable abnormal electricity consumption classification labels and abnormal judgment conditions at all levels.

[0059] 2. For the daily electricity data preprocessed in step S1, introduce a probability model for data analysis and feature mining, and perform abnormality detection and abnormality level discrimination for the daily electricity data to be detected.

[0060] 3. For the ...

Abstract

The invention provides a grading and time-sharing electricity consumption abnormal change analysis method for elderly people living alone. The method comprises the following steps: preprocessing collected electricity consumption data; calculating dynamic thresholds of all levels of daily electricity consumption data, and completing abnormal detection and abnormal state grading judgment of the daily electricity consumption data to be detected; calculating each-level dynamic threshold value of the intra-day hourly electricity consumption data, and completing abnormal detection and abnormal state grading judgment of to-be-detected hourly data; calculating an abnormal electricity utilization proportionality coefficient of the elderly living alone, and evaluating the electricity utilization safety of the user. According to the method, time-grading and grading anomaly detection is carried out on the electricity consumption data of the user, and accurate monitoring and anomaly grading judgment on the household electricity consumption change of the elderly living alone are realized. The method is simple in principle and objective and credible in result, has relatively high popularization value, and can be used for monitoring the household electricity consumption change of the elderly living alone in a long-term and large-scale manner.

Description

technical field [0001] The invention belongs to the technical field of big data analysis and home security measures, and relates to a method for analyzing abnormal changes in power consumption of widowed and lonely elderly people in different levels and time levels. Background technique [0002] With the aging of society, it is showing a rapid upward trend. At this stage, the proportion of widowed and lonely elderly people in the community is also increasing. Because of their physical factors, the special vulnerability of their family conditions and the lack of knowledge about safe electricity use, this group has a huge risk in the safety of household electricity use, and it also makes the existing Some use of video surveillance, smart bracelet monitoring and other methods with high economic requirements is limited. However, it is costly and time-consuming to rely on the way of community staff to visit the site from time to time, and it does not have real-time monitoring ca...
