Embodiment Construction

[0038] In order to make the objectives, technical solutions and advantages of the present invention clearer, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] figure 1 This is the scene diagram of the abnormal behavior monitoring process of the present invention. The intelligent protection system involved in the present invention is composed of WiFi signal transmission equipment, WiFi signal receivers, participants, monitors, GUI control terminal and database, and the monitor is controlled by the GUI control terminal. , the participant produces a series of actions, at which time the WiFi signal receiver obtains WiFi-CSI data. After these data are preprocessed, they are sent to the residual network ResNet50 for identification. According to the preset abnormal behavior list in the background, it is judged whether the behavior is abnormal or not. At the same time, the detected behavior informa...

Abstract

The invention provides an IoT home intelligent protection system and method based on WiFi signal perception, belonging to the technical field of intrusion detection. The present invention utilizes common WiFi signals in the home to sample the CSI in it, realizes the identification of the abnormal behavior of human targets in the home environment of the Internet of Things by training the improved deep learning algorithm model, and formulates a strategy with the unique abnormal behavior to establish a The cross-layer intelligent protection system realizes the identification and suspension of abnormal behavior. The invention designs a smart home protection system with low cost, high precision and good privacy, solves the problem that the smart home system is not humanized enough, and encourages participants to use the smart home.

Description

technical field [0001] The invention belongs to the technical field of intrusion detection, and relates to an IoT home intelligent protection system and method based on WiFi signal perception. The invention utilizes common WiFi signals in homes to sample CSI (Channel State Information) therein, The improved deep learning algorithm model is trained to identify the abnormal behavior of human targets in the home environment of the Internet of Things, and a cross-layer intelligent protection system is established to identify and suspend abnormal behaviors in conjunction with the unique abnormal behaviors to formulate strategies. Background technique [0002] With the continuous development of mobile communication technology, Internet technology and artificial intelligence applications, smart home has become the direction and trend of home system development. However, while enjoying intelligent and convenient services, people should also consider the hidden dangers of information...
