Problems solved by technology

However, behavior recognition technology based on video images is limited by factors such as user privacy and lighting conditions. The solution based on wearable sensors not only requires users to wear sensors at any time, but also is affected by high energy consumption and waste of resources under frequent information interaction. inconvenient

Embodiment Construction

[0037] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, only a part of the embodiments of the present invention, not all the embodiments, and are not intended to limit the present invention.

[0038] The inventors have found that existing smart home devices need to use video image devices or wearable sensor devices to recognize the user's human behavior status (for example: no one, walking, standing, sitting, sleeping, falling and running, etc.), However, these traditional identification schemes have their own disadvantages. For example, the behavior recognition technology based on video images is limited by factors such as user privacy and lighting conditions. Affected by...

Abstract

The invention discloses a non-contact human behavior recognition method and system, the method comprising: continuously receiving channel state information data values ​​sent by a behavior recognition device, filtering the channel state information data values ​​with a preset time length, filtering De-interference data value; pre-classify the filtered channel state information data value to obtain the data set corresponding to human behavior, and use the wireless fingerprint database set to match the data set to obtain human behavior. The solution of the present invention does not need to use any video image equipment or wearable sensor equipment to realize the recognition of human body behavior, and is not limited by factors such as user privacy and lighting conditions, and does not require users to wear sensors at any time, and is not frequently used. Affected by the high energy consumption and waste of resources under information interaction, the recognition of human behavior can be realized without complicated operations, which is very convenient and greatly improves the user experience.

Description

technical field [0001] The invention relates to the field of smart devices, in particular to a contactless human behavior recognition method and system. Background technique [0002] At present, with the continuous development of smart home, in order to provide users with more intelligent services, developers hope that the smart home devices in the residence can automatically recognize the user's human behavior status (for example: no one, walking, standing, sitting, sleep, fall and run, etc.), and predict the next user behavior based on the user's behavior at the moment. Air conditioning, or intelligent services such as increasing or decreasing the wind speed and temperature of the air conditioner. [0003] At present, the method generally adopted for judging the user's behavior state is: by using a video image device or a wearable sensor device to realize judging the user's behavior state. However, behavior recognition technology based on video images is limited by facto...
