Abstract

The invention belongs to the technical field of identification, and relates to a deep learning identification system and method based on wireless network channel state information. A deep learning identification system based on wireless network channel state information, including a wireless signal transmitter, a wireless signal receiver, a control terminal and a cloud server; both the wireless signal receiver and the wireless signal transmitter are equipped with a wireless network card, and the two are separated In the room; the wireless signal transmitter is used to send the wireless signal with CSI information, and the wireless signal receiver is used to obtain the wireless network channel status information in the environment and upload it to the cloud server. The system of the present invention is expected to fill in the gaps in the application of passive identification, and create application examples for passive identification and positioning based on deep learning. The system can be widely used in personnel attendance, smart home intrusion detection, patient monitoring and other fields.

Description

technical field [0001] The invention belongs to the technical field of identification, and relates to a deep learning identification system and method based on wireless network channel state information. This system is a sampling identification of a CSI (Channel State Information) signal using a common WiFi signal. Cooperate with the unique deep machine learning algorithm to carry out model recognition training on the CSI signal of WiFi, thus realizing the recognition system of human body identification. Background technique [0002] In application scenarios such as health monitoring, security detection, and smart home, identification plays a very important role. Existing active identity recognition systems generally use technologies such as fingerprint recognition and iris recognition. Although they can realize recognition and authentication functions, the user under test needs to make specified actions, and there are problems such as expensive equipment and limited recogni...
