Detailed Description

The invention uses the double-layer aluminum alloy door to prevent lawless persons from robbing the house at one time, and then uses the infrared sensor to detect the number of people who open the outer door, controls the opening and closing of the inner door, and prevents the lawless persons from robbing the house.

Please refer to fig. 1, which is a schematic structural diagram of the double-layer aluminum alloy door for preventing others from robbing. The double-layered aluminum alloy door for preventing another person from robbing it of the present invention includes an outer door 10, a doorframe 20 and an inner door 30. The outer door 10 and the inner door 30 are disposed at both sides of the doorframe 20. The door frame 20 is provided with an infrared sensor 21, a controller 22 and an alarm 23. The infrared sensor 21 is arranged at the top of the door frame 20, and can detect the number of people appearing on the door frame; the alarm 23 can be an indicator light or an alarm horn; the controller 22 stores fingerprint information of the resident in advance. The inner door 30 is provided with an electronic lock 31, the electronic lock 31 further comprises a fingerprint identifier 311, and the electronic lock 31 can be arranged at different positions of the door according to different types of the inner door, for example, the positions of a common flat door and a rolling door are different, and should not be taken as a limitation to the invention.

Please refer to fig. 2, which is a circuit block diagram of the double-layer aluminum alloy door for preventing other people from robbing. The output of the infrared sensor 21 is sent to the controller 22, the controller 22 generates a corresponding control signal, and the alarm 23 and the electronic lock 31 are respectively electrically connected with the controller 22 and controlled by the control signal.

The working process of the invention is as follows:

the resident opens the outer door 10 with a key from the outside, and at this time, the inner door 30 is locked, so that a lawbreaker cannot directly grab the house. The resident then steps into the doorframe 20, the infrared sensor 21 is activated to detect the presence of a person in the doorframe, and infrared thermal imaging is converted to an electrical signal which is input to the controller 22. The controller 22 performs image processing and analysis on the results of the infrared thermal imaging, as follows:

1) if the image analysis shows that only one person is present and there is no danger of being caught by other persons, the controller 22 outputs a first unlocking signal to the electronic lock 31. The resident inputs his fingerprint through the fingerprint recognizer 311, and the controller 22 compares the fingerprint information, and outputs a second unlocking signal to the electronic lock 31 if the fingerprint information is identical to the fingerprint information. When two unlocking messages exist, the electronic lock 31 is opened, and the inner door is opened.

2) If the image analysis shows that a plurality of people exist and the danger of others robbing the house can occur, the controller 22 controls the alarm 23 to give an alarm, i.e. the lamp is on or the loudspeaker gives a sound.

As a preferable mode of this embodiment, the double-layer aluminum alloy door further includes a timer 24; the timer 24 is arranged on the inner door 30 or the door frame 20; the timer 24 is electrically connected to the controller 22. The timer 24 can set the timing time by itself, which is 3 seconds in this embodiment. When a resident steps on a door frame and enters the action range of the infrared sensor 21, the timer 24 starts to time, the controller 22 carries out image processing and analysis on the infrared thermal imaging result within 3 seconds, if the image analysis shows that only one resident exists, the controller 22 controls the electronic lock 31 to be opened, and the inner door is opened; if the image analysis shows that there are more than one person, the controller 22 controls the alarm 23 to give an alarm, i.e. the light is on or the speaker is off. By arranging the timer 24, the controller 22 controls the inner door 30 to be opened as long as the infrared sensor 21 detects only one person within the specified time, so that the trouble of unlocking the door by a resident is avoided, and the time difference is reasonably utilized to prevent other people from robbing the door.

The above detailed description shows the working process of the present invention for realizing door opening, and in order not to affect the normal door exit and door locking of the resident in the preferred scheme of using the timer 24 to automatically open the door, the present embodiment further includes the following anti-misoperation steps: the controller 22 detects the open/close state of the electronic lock 31 at any time, when the controller 22 detects that the electronic lock is changed from the open state to the close state, namely the door is opened and locked, the timer 24 starts to count time, even if the infrared sensor 21 detects only one person on the doorframe 20 within 30 seconds, the controller 22 does not control the electronic lock 31 to be opened, and the electronic lock 31 is prevented from opening the inner door 30 again due to an automatic door opening mechanism after the door is locked.

It is worth to say that the invention can be applied to not only the household life to prevent lawless persons from robbing into the house when the resident opens the door, but also the occasion of allowing only one person to enter, such as bank treasury or VIP safe case, or the single person intelligent detection after the examination room or the security inspection is combined with the metal detection device.
