Method for identifying in-bed state of person living alone

Abstract

The invention discloses a method for identifying the in-bed state of a person living alone. The method comprises the steps of installing a vibration sensor with an Internet of Things function at the edge of a bed, transmitting data to a server at regular time, and enabling server-side software to recognize and judge whether the person exists in the bed or not and the activity state of the person through a vibration mode. The method comprises the following steps of (1) collecting bed vibration amplitude data through the vibration sensor, and uploading the bed vibration amplitude data to the server through the Internet of Things; (2) carrying out time slice division on the vibration time sequence data; (3) calculating vibration amplitude representation vectors corresponding to the time slices; (4) judging the in-bed state of the person, specifically, judging the in-bed state of the person in each time slice according to the corresponding vibration amplitude vector obtained in the step (3); and (5) counting the in-bed state of the person in each time slice obtained in the step (4) to obtain the in-bed state of the person in the whole time period.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a method for identifying the state of a person living alone in bed. Background technique [0002] As the aging society is getting worse, the number of people living alone is also increasing year by year. It has become an important daily work for community workers to judge whether people are safe at home; the bed status recognition device is to assist community workers to complete this work efficiently. Effective means; at present, the identification of people's home status can be realized through microwave, visual intelligence and other methods, but due to high cost, power supply security, privacy protection and other issues, it cannot be promoted on a large scale. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the prior art and provide a method for identifying the bed state of a person living alone. The present invention coll...
