Problems solved by technology
[0004] 1. Since the existing smart door system does not have a linked camera, it cannot reflect the situation on site and cannot retain intrusion images
[0005] 2. The existing smart door system cannot judge and respond to violent intrusions (smashing locks, prying doors, and splitting doors) that do not cause the door sensor to be disconnected
[0007] In summary, the existing smart door systems generally have defects that cannot judge violent intrusion and malicious interference door magnetic intrusion

The invention discloses a method for judging malicious intrusion behavior and an intelligent door system. The method includes: continuously collecting the three-axis acceleration and magnetic field strength of the door at multiple times; value; calculate the absolute value of the three magnetic field strength changes between four consecutive moments; if they are greater than the normal fluctuation threshold of the magnetic field strength, it is determined that a malicious intruder uses a magnet to interfere with the door sensor, and an alarm signal is sent; if the peak value of the absolute value of the acceleration change is greater than Three times the normal fluctuation threshold of the acceleration, and the time interval between two adjacent peaks of the absolute value of the acceleration change is greater than the time threshold, it is determined that there is a violent intrusion behavior, and an alarm signal is sent; if there is no peak value, the absolute value of the maximum acceleration change is greater than the normal acceleration Three times the fluctuation threshold, it is determined that there is a violent intrusion, and an alarm signal is sent. The method for judging malicious intrusion behavior and the smart door system can judge violent intrusion and malicious interference door magnetic intrusion.
Description
technical field [0001] The invention relates to the technical field of smart doors, in particular to a method for judging malicious intrusion behavior and a smart door system. Background technique [0002] At present, the existing smart door system usually has a controller, a door sensor, and a smart door lock. The door sensor is installed on the edge of the door, which is convenient for sending a wireless alarm signal to the controller when it is turned on or off. The existing smart door system responds to the switch state of the door through the on-off of the door magnetism, opens the door within the arming time, sends an intrusion signal through the controller, and remotely opens the door through the smart door lock. [0003] The shortcomings of the existing smart door system are mainly as follows: [0004] 1. Since the existing smart door system does not have a linked camera, it cannot reflect the situation on site and cannot retain intrusion images. [0005] 2. The ex...
