Description

Technical Field

[0001] The present invention relates to the field of home security, and in particular to an intelligent AI-based home security real-time video anti-shielding defense system. Background Art

[0002] With the development of the Internet and the rapid popularization of mobile Internet 4G and 5G, smart network cameras are currently widely used in home security management for remote home monitoring and anti-theft alarms, but there are still serious deficiencies in fire prevention, explosion prevention, and water leakage prevention in home security. For example, patent document CN204833642U, named "Anti-shielding Intelligent Network Video Linkage Alarm System", can automatically detect the wireless alarm system of WiFi intelligent network cameras. If it is subject to malicious radio shielding, it can quickly send the video image signal and alarm signal of the monitored scene to the remote monitoring terminal, to the family's smart phone or the monitored computer. At this time, the family can take emergency response measures or notify relevant personnel to check the scene, thus avoiding the occurrence of cases and ensuring personal safety and property safety; however, its defects are: (1) The mobile phone at the receiving terminal can only passively receive the motion detection, voice intercom, camera pan / tilt rotation and other functions pushed by the smart network camera, but cannot use the smart network camera to remotely control the home security equipment in the reverse direction; (2) In the anti-shielding scheme, only the detection of the interference signal source is considered to send a group alarm through the APP. However, in actual application, it is found that when there are radio devices with the same frequency near the smart network camera, including various wireless detectors, the alarm system of the smart network camera can be triggered to work within a short period of about 2 seconds of sending wireless signals, resulting in false alarms; (3) Unable to detect water pipe leaks and gas leaks; (4) It is not possible to use a mobile phone to remotely activate the home exhaust system to vent the explosion; (5) It is not possible to use a mobile phone to remotely shut off the valves of the water and gas pipes at home; (6) It is impossible to use a mobile phone to remotely activate the fire extinguishing device at home; (7) It is impossible to use a mobile phone to remotely unlock the door or activate the alarm; For example, patent document CN114879525B, entitled "A smart home-watching system based on a complete set of household appliances", provides a solution in which the data flow of smart home-watching is interactive, a complete set of household appliances forms a smart home-watching system, the complete set of household appliances are networked to automatically monitor and report data to realize the smart home-watching system, configure the home-watching time period of the equipment, remotely open or close the smart home-watching and other key contents, and as a separate home-watching device, it monitors and processes the device data through the cloud server; however, its defects are: based on a single intelligent networked anti-theft monitoring of electrical equipment at home, if there is an abnormality, an alarm call or short message is issued, after receiving the alarm call or short message, the user views the alarm information and real-time video through the client, and after understanding the cause of the alarm, handles the abnormal situation, and cannot remotely control the fire prevention, water pipe leakage, gas leakage, ventilation window and remote fire extinguishing at home; For example, patent document CN205788638U, entitled "A smart light-type home safety intelligent control system", aims to propose a smart light-type home safety intelligent control system, so that smart homes can pay more attention to the safety of family life while bringing great convenience to people's lives; its defects are: by establishing two scenarios, one is that if the smoke sensor is abnormal or the home environment changes, such as cooking, a false alarm will be generated. If the fire protection system is automatically turned on for spraying, the fire extinguishing device will be immediately started, thus causing serious destructive pollution to the walls and ground of the home environment; second, when there is a gas leak at home, family members need to go to the scene for rescue in person after receiving the information, and cannot use mobile phones for remote control to close the valve. More importantly, when encountering interference shielding, the transmitted signal is blocked and fails, so the receiving terminal cannot receive any information, resulting in missed alarms, and cannot push multiple people to receive information in a timely and accurate manner; For example, the patent document CN115938063A, entitled "A multifunctional household kitchen fire alarm device based on the Internet of Things", is an IoT model in which the gas source and power supply are immediately shut down when the kitchen is left alone, the exhaust is turned on, and the alarm is reported to the platform and the mobile phones of the family members, requiring rescue. The defect is that the rescue is not timely and not perfect, and some accidents are caused by the lack of management at home, so it is not possible to use the mobile phone to remotely manage and control the safety facilities at home; Some users use Bluetooth, a wireless method of IoT smart home, to transmit data. This poses a security risk of being blocked and intercepted by jammers and causing failure. In addition, the information received is not real-time and the response speed is slow. It is not possible to quickly and accurately confirm the risks in the home. The operation is complicated and there is information security. Although the wire connection method is safe, it requires wiring in advance when the house is decorated, which is very troublesome and labor-intensive, and the position cannot be changed arbitrarily. Summary of the invention

[0003] The technical problem to be solved by the present invention is: a real-time video anti-shielding defense system based on intelligent AI home security, which solves the problem that the receiving terminal in the prior art can only passively receive the warning information pushed by the intelligent network camera and the false warning information pushed when the same-frequency interference is shielded, but cannot reversely operate and control the security and fire-fighting equipment in the home, and can immediately push the alarm when it really encounters electronic interference shielding.
