Abstract

The invention discloses a household intrusion detection method, device and system based on a WiFi signal. A wireless AP device is arranged in a 6m range of a wireless router, and a circle formed by taking a connecting line of the wireless AP device and a router device as a diameter is located in an area where an intruder is predicted to pass through; the wireless AP device is connected to a wireless network of a wireless router, the wireless AP device continuously sends ICMP data packets to the wireless router device at equal time intervals, the wireless router returns the ICMP data packets to the wireless AP device, the wireless AP device analyzes the returned ICMP packets, obtains the time sequence data composed of channel information data of RSSI and CSI, processes the time sequence data, calculates the stability degree of the signal-to-noise ratio in the time sequence data, and judges whether intrusion occurs or not. The device is simple in structure, low in cost, free of privacy problems and capable of accurately recognizing the occurrence of intrusion.

Description

technical field [0001] The invention belongs to the technical field of network security, relates to home security technology, and is a home intrusion detection method based on WiFi signals. Background technique [0002] Intrusion detection is an important means to protect the personal safety and property safety of family members. With the development of economy and the advancement of science and technology, intrusion detection in the family environment has been paid more and more attention. [0003] Existing intrusion detection techniques can be divided into two categories, vision-based intrusion detection and non-vision-based intrusion detection. Vision-based intrusion detection mainly uses cameras to monitor and perform image recognition on videos. The detection requires a lot of calculations. At night, the cameras need to have night vision functions and there are privacy issues. In non-visual detection, the equipment based on the original WiFi signal is too expensive, an...
