Embodiment Construction

[0076] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0077] combine Figure 1 to Figure 4 A human behavior recognition method based on WIFI channel state information, comprising the following steps:

[0078] Step 1: Behavior recognition system construction: build two sets of channel state information data collection equipment based on Atheros network card, one of which is used as the transmitter, and the other set of channel state information data collection equipment is used as the receiver; establish a service end, the receiving end is connected to the server end.

[0079] Step 2: Data collection: The transmitter and the receiver are placed at intervals, the transmitter transmits WIFI signals to the receiver, the personnel stand between the transmitter and the receiver, and make corresponding actions, the receiver will receive the original data sent to the server for data...

Abstract

The invention discloses a human body behavior identification method based on WIFI channel state information, which belongs to the technical field of behavior identification, and aims to solve the problems that a current behavior identification technology excessively depends on a sensor technology, is worse in user experience and higher in cost, is easily influenced by the factors, such as the light rays, etc., and easily leaks the privacy. Through the processes of behavior identification system establishment, data collection, data model training, action endpoint detection and online identification, the basic human body behavior actions in daily life are identified with high precision, and the change of the WIFI signals and the behavior prediction results are displayed in real time. The method has the advantages that an absolute sight distance path is not required, the activity range is large, the concealment performance is good, wall penetrating can be achieved, no requirement for light rays exists, the cost is low, and the large-scale deployment is easy to achieve.

Description

technical field [0001] The invention relates to the field of human behavior recognition, in particular to a human behavior recognition method based on WIFI channel information. Background technique [0002] With the continuous improvement of the national economy, people's requirements for the quality of life are constantly improving, and they are gradually developing in the direction of intelligence and comfort. Including higher requirements for daily entertainment, home life, medical level and other fields, which also gave birth to the continuous development and progress of science and technology in these fields. In recent years, with the rapid development of the field of artificial intelligence and people's demand for intelligent monitoring, smart home and new human-computer interaction is increasing. Human Activity Recognition (HAR) has become a popular research direction in the fields of pattern recognition, computer vision, and wireless perception. In academia, many e...
