[0027] The main technical idea of the present invention is to first judge whether the door and window are in the closed state. When it is judged to be closed, the human body sensor and detector are activated. When the photoelectric detector detects abnormal unlocking action or the human body stays or locks for longer than the agreed time When the vibration exceeds the approximate amount, the camera/alarm module is activated to take a photo and is sent to the user equipment of the authorized person through the data transmission module through the wireless network. At the same time, the facial image is compared, and when the facial image characteristics of the authorized person are not met, the camera/alarm module is activated for sound and light alarm. It enables users to discover illegal intrusions such as theft in time through user equipment, and realizes a safe and reliable anti-theft method and system without distance restriction.
[0028] Attached below figure 1 , Attached figure 2 The anti-theft alarm lock capable of taking photos and sending messages of the present invention will be further described in detail.
[0029] Participate figure 1 , Attached figure 2 , An anti-theft alarm lock capable of taking photos and sending messages, comprising a lock body 1, a bolt 2, a lock buckle 3, and is characterized in that the lock body 1 is also provided with a processor 4, a camera/alarm module 5, and data The sending module 6, the photoelectric detector 7, the human body sensor 8, the vibration sensor 15; the lock body 1 marble pipe 11 is provided with a through hole 13; the photoelectric detector 7 is connected to both ends of the through hole 13, and the movement energy of the marble 12 The through hole 13 is closed; the lock 3 is provided with a pressure sensor 9; the photoelectric detector 7, the human body sensor 8, and the pressure sensor 9 are respectively connected to the processor 4, and the processor 4 controls the photographing /Alarm module 5, data sending module 6 work; the photographing/alarm module 5 is concealedly installed on the door/window frame, and the data sending module 6 can send the photographed pictures generated by the photographing/alarm module via wireless network To the user's device.
[0030] When the key is inserted into the lock body 1, the movement of the pin 12 can cause the through hole 13 of the pin pipe 11 to be closed. The photodetector 7 can detect the closed size of the through hole 13 to generate different signal values.
[0031] The workflow is as follows:
[0032] Step 1: First, pre-store the face image of the authorized person in the processor 4, and pre-store the photoelectric signal value when the correct key is inserted.
[0033] Step 2: When the door is locked, the tongue 2 is located in the buckle 3, and the tongue 2 touches the pressure sensor 9 in the buckle 3. When the processor 4 detects the pressure signal of the pressure sensor 9, the human body sensor 8 and the photoelectric detector are activated 7;
[0034] Step 3: When the photoelectric detector 7 or the human sensor 8 or the signal line 10 on the lock body fixing screw obtains the sensing signal, the following judgments are made:
[0035] 3-1 The photodetector 7 detects that a key or other object is inserted into the lock body 1, and the processor 4 records the number of insertions and records the insertion time. If the number of insertions and the insertion time do not exceed the agreed value, go to step 8. Otherwise, go to step 5.
[0036] 3-2 The human body sensor 8 detects that there is a human body staying in front of the lock body 1, if the stay time does not exceed the agreed value, go to step 8, otherwise go to step 5.
[0037] 3-3 Vibration sensor 15 detects that the lock body is vibrated. If the vibration does not exceed the approximate amount, go to step
[0038] Step 8, otherwise go to step 5.
[0039] 3-4 The signal line 10 of the lock body fixed passage is damaged, go to step 5.
[0040] Step 5: The processor 4 starts the photographing/alarm module, sends the photographed face image to the user equipment of the authorized person via the wireless network, and goes to step 6.
[0041] Step 6: Perform feature extraction on the captured face image and compare it with the facial image of the authorized person in the processor 4. When the facial feature comparison result does not match the facial image feature of the authorized person, go to step 7. If yes, go to step 8.
[0042] Step 7: Start the sound and light alarm device in the photo/alarm module 5.
[0043] Step 8: Do not start the camera/alarm module 5, go to step 2.
[0044] The lock body 1 described in the above structure and work flow is a pin lock, the human body sensor 8 is an electric field human body sensor, a pyroelectric human body sensor, and the processor 4 is a single-chip microcomputer or a programmable controller. The photo/alarm module 5 is any combination of lighting, flashing, voice alarm, recording device, and photo recording device. The wireless transmission mode used by the data sending module 6 includes SMS, MMS, CMNET, GSM, GPRS, Radio, 3G, CDMA, TD_SCDMA, the user equipment includes a computer, a mobile phone or a special receiving device, the lock body 1 fixed path signal line 10 is the conductive wire of the lock body fixing screw, and the conductive wire is covered by the screw. The nut conducts the conductive wire when tightening, and the conductive wire is in a disconnected state when the screw is loosened.
[0045] The present invention has been schematically described above with reference to the accompanying drawings and embodiments. The description is not restrictive, and the accompanying drawings are only one embodiment. Those skilled in the art should also understand that under the enlightenment of the solution of the present invention, other people may also make designs similar to the present invention.
