Problems solved by technology

[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, etc., but due to high cost, power supply security, privacy protection and other issues, it cannot be promoted on a large scale

Embodiment Construction

[0037] The present invention will be further described below in combination with specific embodiments and accompanying drawings. The identification method includes the following steps (such as Figure 1-2 Shown): 1. Collect the bed vibration amplitude data through the vibration sensor, and upload it to the server through the Internet of Things. Include the following steps:

[0038] Vibration sensors are sensors used to detect impact force or acceleration, usually using piezoelectric devices that generate charges when stress is added; according to functions, they can be divided into: relative type, inertial type; according to the principle of electromechanical transformation, they can be divided into: electric type, piezoelectric type, eddy current type, inductive type, capacitive type, resistive type, photoelectric type, etc. This invention has no requirements on the type of vibration sensor, as long as the vibration sensor that meets the following performance indicators can...

Abstract

The invention discloses a bed state recognition method for a person living alone. A vibration sensor with an Internet of Things function is installed on the edge of the bed to send data to a server at regular intervals. The server-side software judges whether there is a person in the bed and the activity state of the person through vibration pattern recognition. The steps are as follows: (1) collect the vibration amplitude data of the bed through the vibration sensor, and upload it to the server through the Internet of Things; (2) divide the vibration time series data into time slices; (3) calculate the vibration amplitude representation vector corresponding to the time slice; ( 4) Discrimination of the person's bed state: according to the vibration amplitude vector obtained in step (3), the person's bed state of each time slice is judged. (5) Statistically count the bed status of the person in each time slice obtained in step (4), and obtain the bed status of the person in the entire 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...
