Description

Technical Field

[0001] The present invention relates to the technical field of collecting and controlling people entering homestays, and in particular to a system and method for capturing people entering homestays booked online. Background Art

[0002] B&B refers to small accommodation facilities that utilize idle real estate resources such as local houses and use guest rooms for accommodation, providing tourists with a chance to experience the local nature, culture, production and lifestyle.

[0003] Online booking refers to housing that is provided to the public by units or individuals through Internet service platforms, using "hours" or "days" as the settlement unit, and online booking and transaction completion. It has various titles such as online rental housing, daily rental housing, short-term rental apartments, serviced apartments, homestays, inns, cinema rooms, landscape rooms, family rooms, etc. It is a new form of accommodation industry with the nature and characteristics of hotel industry.

[0004] However, the current online registration real-name rate of online booking rooms and homestays is low, the accommodation personnel are complex, and illegal acts are prone to occur inside the venue, which has become a difficult and painful point in public security management. Moreover, due to the characteristics of their business model, the personnel registration management industry of online booking rooms and homestays cannot achieve the same effect of information control of accommodation personnel as hotels. Moreover, the intensity of information control of online booking room and homestay operators for occupants is inversely proportional to the willingness to cooperate with the information control of occupants, because the higher the intensity of information control, the lower the occupancy rate of online booking rooms and homestays, so operators are not willing to cooperate, and information control requires control costs, while homestays and online booking rooms do not have front desk staff like hotels. If control is required, the labor costs of operators will be increased; if cameras are installed directly in the building where the homestay or online booking room is located, it will have a negative impact on the business of the homestay or online booking room operator. Therefore, for homestays and online booking rooms, there is great resistance to directly installing cameras, not to mention that the cost and energy consumption cost of camera installation will also increase the operating costs of homestay and online booking room operators. Therefore, how to balance the respective needs of the accommodation personnel, business owners, and public security organs has been a technical problem that technical personnel in this field have always wanted to solve. Thus, a technical solution of capture equipment and capture method with unconscious portrait capture as the entry point is provided, which not only provides convenience for the accommodation personnel to reduce their resistance, but also does not affect the service income of the business owners, and can also enhance the public security organs' ability to control online-booked houses and homestays. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a system and method for capturing people entering online homestays, so as to supervise the people entering and leaving the homestays without affecting the operation of the homestays or increasing the operating costs of the homestays; and when public security cases or criminal cases require investigation of the homestays, the uploaded data is analyzed through the identification system of the public security department, so that the public security department can more easily identify and determine the relevant personnel, thereby improving the work efficiency of public security officers.

[0006] The technical solution adopted by the present invention is: A capture system for people entering a room of an online-booked homestay, including a capture system fixed to a door, the capture system including a processor, a door opening and closing sensor, a camera, a memory and a communication device, the door opening and closing sensor, the camera, the memory and the communication device are electrically connected to the processor respectively, the door opening and closing sensor transmits the opening and closing state of the door to the processor, the camera transmits the corresponding picture facing the outer side of the door to the processor, the memory is used to temporarily store videos or photos taken by the camera, the communication device transmits the videos or photos temporarily stored in the memory to the data system of the public security department, and the capture system is powered by a room power supply or a battery.

[0007] A further improvement of the present invention is that the door opening and closing sensor device includes a sensor A for determining whether the door lock tongue is located in the lock slot, and the sensor A is electrically connected to the processor.

[0008] A further improvement of the present invention is that the door opening and closing sensor device also includes an angle detector for detecting the swing angle of the door.

[0009] A further improvement of the present invention is that the camera device includes a camera A for shooting video.

[0010] A further improvement of the present invention is that the camera device also includes an infrared camera for shooting in low light conditions.

[0011] A further improvement of the present invention is that the camera device also includes a camera B for taking pictures.

[0012] The method for capturing images using the capture system as described above comprises the following steps: 1) The processor determines whether the door is open through the door opening and closing sensor device. If the processor determines that the door is open, the camera device takes a video, and the processor temporarily stores the real-time video data transmitted back by the camera device in the memory; If the processor determines that the door is not open, the imaging device only transmits the real-time video data to the processor, and the processor determines whether there is anyone outside the room based on the real-time video data transmitted back by the imaging device; 2) If the processor determines that there is someone outside the room, the imaging device takes a photo, and the processor temporarily stores the photo data taken by the imaging device in the memory; If the processor determines that there is no one outside the room, it goes back to step 1) again, and the processor continues to determine whether there is anyone outside the room based on the real-time video data transmitted back by the imaging device; 3) After the imaging device takes a photo, it goes back to step 1) again, and the processor continues to determine whether the door is opened again through the door opening / closing sensing device; If the person captured by the imaging device leaves the shooting range of the imaging device before the processor determines that the door is opened through the door opening / closing sensing device, the processor deletes the photo data temporarily stored in the memory; 4) After the imaging device takes a video, the processor determines whether the door is closed through the door opening / closing sensing device, If the processor determines that the door is closed, the imaging device stops shooting the video; If the processor determines that the door is not closed, it goes back to step 1) again, the imaging device continues to shoot the video, and the processor temporarily stores the real-time video data transmitted back by the imaging device in the memory; When the real-time video data temporarily stored in the memory reaches the maximum capacity, If the imaging device has captured someone entering or leaving the room, the processor automatically transmits the data temporarily stored in the memory to the data system of the public security department through the communication device. While transmitting, the processor immediately deletes the data that has been transmitted in the memory, and the processor continues to temporarily store the real-time video data captured by the imaging device in the memory; If the imaging device still has not captured someone entering or leaving the room, the processor automatically deletes the data temporarily stored in the memory, and the processor continues to temporarily store the real-time video data captured by the imaging device in the memory; 5) After the imaging device stops shooting, the processor determines whether someone enters or leaves the room based on the real-time video data transmitted back by the imaging device, If the processor determines that no one enters or leaves, the processor deletes the data temporarily stored in the memory, and goes back to step 1) again, and the processor continues to determine whether the door is opened again through the door opening / closing sensing device; If the processor determines that someone enters the room, the processor transmits the data temporarily stored in the memory to the data system of the public security department through the communication device, and goes back to step 1) again, and the processor continues to determine whether the door is opened again through the door opening / closing sensing device; If the processor determines that someone has left the room, the processor determines whether there is someone outside the room based on the real-time video data transmitted back by the imaging device; 6) If the processor determines that there is someone outside the room, the imaging device starts to take a photo, and the processor temporarily stores the photo data taken by the imaging device in the memory; If the processor determines that there is no one outside the room, the processor transmits the data temporarily stored in the memory to the data system of the public security department through the communication device. After the processor completes the data transmission through the communication device, it deletes the data temporarily stored in the memory; 7) After the imaging device takes a photo, it returns to step 5) again. The processor determines whether there is someone outside the room again based on the real-time video data transmitted back by the imaging device; 8) After the processor transmits the data to the data system of the public security department, it returns to step 1) again. The processor continues to determine whether the door is opened again through the door opening and closing sensing device.

[0013] A further improvement of the present invention is that in step 1), when the sensor A in the lock groove does not detect the signal of the lock tongue in the lock groove and the angle detector detects that the opening angle of the door is greater than or equal to 30 degrees, the processor determines that the door is in an open state.

[0014] A further improvement of the present invention is that in step 4), when the sensor A in the lock groove detects the signal of the lock tongue in the lock groove or the angle detector detects that the opening angle of the door is 0 degrees, the processor determines that the door is in a closed state.

[0015] A further improvement of the present invention is that in step 5), when the door is a left-opening door, if the person captured by the imaging device enters the picture from the right side of the picture and leaves the picture from the left side after passing through the door frame, the processor determines that someone has entered the room; if the person captured by the imaging device enters the picture from the left side of the picture and leaves the picture from the right side after passing through the door frame, the processor determines that someone has left the room. When the door is a right-opening door, if the person captured by the imaging device enters the picture from the left side of the picture and leaves the picture from the right side after passing through the door frame, the processor determines that someone has entered the room; if the person captured by the imaging device enters the picture from the right side of the picture and leaves the picture from the left side after passing through the door frame, the processor determines that someone has left the room.

[0016] In steps 2) and 6), when the imaging device takes a photo, the processor selects a screenshot of the picture that clearly shows the captured person from the real-time video data transmitted back by camera A and temporarily stores it in the memory as photo data.

[0017] In step 2) and step 6), when the camera device takes pictures, the processor temporarily stores the continuous shooting photo data transmitted back by camera B in the memory.

[0018] The processor temporarily stores the screenshots of the continuous-shot photo data transmitted by the camera B, which clearly show the photographed person, in the memory as photo data.

[0019] The continuous shooting speed of the camera B is more than 3 frames per second.

[0020] When the light outside the room is low, the infrared camera is used to shoot videos and photos. The processor determines whether there is someone outside the door and whether someone enters or leaves the room based on the video data sent back by the infrared camera. The processor temporarily stores the video data or photo data sent back by the infrared camera in the memory.

[0021] The door capture system includes a tablet electronic device fixed to the outer end surface of the door, the processor is the processor of the tablet electronic device, the memory is the memory of the tablet electronic device, the communication device is the communication device of the tablet electronic device, and the camera A, infrared camera and camera B are arranged in the screen of the tablet electronic device.

[0022] The door capture system also includes a cat's eye display screen fixed to the inner end surface of the door. When the cat's eye display screen displays a picture, the cat's eye display screen displays the video data transmitted by the camera A to the processor in real time.

[0023] The display of the flat-panel electronic device is used to display advertisement pictures and life information pictures.

[0024] The beneficial effects of the present invention are: The online-booked homestay room-entry capture system and capture method of the present invention can realize the maximum automatic collection and control of the information of the people entering and leaving the homestay, without affecting the operation of the homestay or increasing the operating costs of the homestay; and when encountering public security cases or criminal cases that require investigation of the homestay, the uploaded data is analyzed through the identification system of the public security department, so that the public security department can more easily identify and determine the relevant personnel, thereby improving the work efficiency of public security officers.

While transmitting, the processor 1 immediately deletes the data that has been transmitted in the memory 4, and the processor 1 continues to temporarily store the real-time video data captured by the imaging device 3 in the memory 4; If the imaging device 3 still has not captured someone entering or leaving the room, the processor 1 automatically deletes the data temporarily stored in the memory 4, and the processor 1 continues to temporarily store the real-time video data captured by the imaging device 3 in the memory 4; 5) After the imaging device 3 stops shooting, the processor 1 determines whether someone enters or leaves the room based on the real-time video data transmitted back by the imaging device 3, If the processor 1 determines that no one enters or leaves, the processor 1 deletes the data temporarily stored in the memory 4, and returns to step 1) again. The processor 1 continues to determine whether the door is opened again through the door opening and closing sensing device 2; If the processor 1 determines that someone enters the room, the processor 1 transmits the data temporarily stored in the memory 4 to the data system of the public security department through the communication device 5, and returns to step 1) again. The processor 1 continues to determine whether the door is opened again through the door opening and closing sensing device 2; If the processor 1 determines that someone leaves the room, the processor 1 determines whether there is someone outside the door based on the real-time video data transmitted back by the imaging device 3; 6) If the processor 1 determines that there is someone outside the door, the imaging device 3 starts to take a photo, and the processor 1 temporarily stores the photo data captured by the imaging device 3 in the memory 4; If the processor 1 determines that there is no one outside the room door, the processor 1 transmits the data temporarily stored in the memory 4 to the data system of the public security department through the communication device 5. After the processor 1 completes the data transmission through the communication device 5, it deletes the data temporarily stored in the memory 4; 7) After the imaging device 3 takes a photo, it returns to step 5) again. The processor 1 determines again whether there is anyone outside the room door through the real-time video data transmitted back by the imaging device 3; 8) After the processor 1 transmits the data to the data system of the public security department, it returns to step 1) again. The processor 1 continues to determine whether the room door is opened again through the door opening and closing sensing device 2.

[0034] In the said step 1), when the sensor A6 of the lock groove does not detect the signal of the lock tongue in the lock groove and the angle detector 8 detects that the opening angle of the room door is greater than or equal to 30 degrees, the processor 1 determines that the room door is in the open state.

[0035] In the said step 4), when the sensor A6 of the lock groove detects the signal of the lock tongue in the lock groove or the angle detector 8 detects that the opening angle of the room door is 0 degree, the processor 1 determines that the room door is in the closed state.

[0036] In the said step 5), when the room door is a left-opening door, if the person captured by the imaging device 3 enters the picture from the right side of the picture and leaves the picture from the left side after passing through the door frame, then the processor 1 determines that someone enters the room; if the person captured by the imaging device 3 enters the picture from the left side of the picture and leaves the picture from the right side after passing through the door frame, then the processor 1 determines that someone leaves the room; when the room door is a right-opening door, if the person captured by the imaging device 3 enters the picture from the left side of the picture and leaves the picture from the right side after passing through the door frame, then the processor 1 determines that someone enters the room; if the person captured by the imaging device 3 enters the picture from the right side of the picture and leaves the picture from the left side after passing through the door frame, then the processor 1 determines that someone leaves the room.

[0037] In the said steps 2) and 6), when the imaging device 3 takes a photo, the processor 1 selects a picture screenshot that clearly shows the captured person from the real-time video data transmitted back by the camera A7 and temporarily stores it in the memory 4 as photo data.

[0038] In the said steps 2) and 6), when the imaging device 3 takes a photo, the processor 1 temporarily stores the continuous shooting photo data transmitted back by the camera B10 in the memory 4.

[0039] The processor 1 selects a picture screenshot that clearly shows the captured person from the continuous shooting photo data transmitted back by the camera B10 and temporarily stores it in the memory 4 as photo data.

[0040] The continuous shooting speed of the camera B10 is more than 3 frames per second.

[0041] When the light outside the room is low, the infrared camera 9 is used to shoot videos and photos. The processor 1 determines whether there is someone outside the door and whether someone enters or leaves the room based on the video data sent back by the infrared camera 9.

[0045] The door of the online-booked homestay opens inward. Example 1

[0046] When a guest checks in, he / she comes to the door of the room. At this time, the processor 1 determines that the door is not opened through the door opening and closing sensor 2. The processor 1 determines that there is someone outside the door through the real-time video data transmitted by the camera 3. At this time, the camera 3 takes photos, and the processor 1 temporarily stores the photo data taken by the camera 3 in the memory 4; then the guest opens the door and enters the room. During the above process, the camera 3 will take a video, and the guest will inevitably pass through the door when entering the room. At this time, the camera 3 will take a video of the guest entering the room, and then the processor 1 will temporarily store the video containing the process of the guest entering the room in the memory 4; after entering the room, the guest will close the door. After the door is closed, the processor 1 transmits the photo data and video data temporarily stored in the memory 4 to the data system of the public security department through the communication device 5. Example 2

[0047] When the occupied guest is in the room, if the room door remains closed and a passerby passes by the door outside the room, when the passerby appears within the shooting range of the shooting device 3, the shooting device 3 takes a photo of the passerby's appearance and temporarily stores it in the memory 4. After the passerby leaves the shooting range of the shooting device 3, since the door has not been opened yet, the processor 1 deletes the photo of the passerby's image temporarily stored in the memory 4. Embodiment 3

[0048] When the occupied guest is in the room, if the room door remains open and the shooting device 3 is in a video shooting state, and a passerby passes by the door outside the room, when the passerby appears within the shooting range of the shooting device 3, the shooting device 3 takes a photo of the passerby's passing-by image and temporarily stores it in the memory 4. After the door is closed, the processor 1 determines that no one is entering or leaving the room, so the processor 1 deletes the video of the passerby's image temporarily stored in the memory 4; if the memory 4 has been filled with temporarily stored data due to the door being open for too long, and at this time the shooting device 3 still has not captured anyone entering the room, so the processor 1 deletes the video temporarily stored in the memory 4. Embodiment 4

[0049] After the guest checks in and the room door is closed, when a visitor comes to visit, the visitor arrives at the door of the room. At this time, the processor 1 determines through the door opening and closing sensing device 2 that the door is in an unopened state, and the processor 1 determines that there is someone outside the room through the real-time video data transmitted by the shooting device 3. At this time, the shooting device 3 takes a photo, and the processor 1 temporarily stores the photo data taken by the shooting device 3 in the memory 4; then when the guest opens the door and the visitor enters the room, during the above process, the shooting device 3 will shoot a video, and when the visitor enters the room, the visitor will inevitably pass by the door. At this time, the shooting device 3 will take a video of the visitor entering the room, and then the processor 1 will temporarily store the video containing the process of the visitor entering the room in the memory 4; after the visitor enters the room, as long as the door is closed, after the door is closed, the processor 1 transmits the photo data and video data temporarily stored in the memory 4 to the data system of the public security department through the communication device 5; if the door is forgotten to be closed and the memory 4 has been filled with temporarily stored data, since the shooting device 3 has already captured someone entering the room at this time, the processor 1 automatically transmits the data temporarily stored in the memory 4 to the data system of the public security department and deletes the data already stored in the memory 4 so that the real-time video data captured by the shooting device 3 can still be temporarily stored in the memory 4. Embodiment 5

[0050] When a guest orders takeout service, the door of the room is closed. When the delivery person arrives at the door of the room, at this time, the processor 1 judges that the door is in the unopened state through the door opening and closing sensing device 2, and the processor 1 judges that there is someone outside the room through the real-time video data transmitted by the camera device 3. At this time, the camera device 3 takes a photo, and the processor 1 temporarily stores the photo data taken by the camera device 3 in the memory 4; then after the guest opens the door and the visitor enters the room, during the above process, the camera device 3 will take a video. However, since the delivery person will not enter the room and the guest will not leave the room, after the door is closed, the processor 1 will delete the data temporarily stored in the memory 4. Embodiment 6

[0051] When the people in the room leave the room, after the door is opened, the camera device 3 will take a video. When the people in the room leave the room, close the door and leave, since the processor 1 judges that someone has left the room according to the picture taken by the camera device 3, and takes a photo of the person leaving outside the room after the door is closed. When there is no one outside the door, the processor 1 transmits the data temporarily stored in the memory 4 to the data system of the public security department.

[0052] The data transmitted to the data system of the public security department is stored, so as to realize the maximum automatic collection and control of the people entering and leaving the homestay, and will not affect the operation of the homestay, nor increase the operating cost of the homestay; and when it is necessary to investigate the homestay in case of public security cases or criminal cases, the above uploaded data is analyzed through the identification system of the public security department's background, so that the public security department can more easily identify and determine relevant personnel and improve the work efficiency of the police.

[0053] This system can be innovatively transformed on the basis of an intelligent cat's eye, that is, an intelligent cat's eye is set inside the guest room door, and the external cat's eye device is equipped with a screen panel with a function of capturing people. Using the camera sensing algorithm or the infrared sensing module, it captures people when it senses someone in front of the door. It also uses the docking door magnet or the intelligent door lock to sense the door state, and keeps the capturing action when the door is not closed until the door is closed. The data is in accordance with the national standards of GB28181 and GA1400, and is connected to the public security organ's background through the network in the guest room.

[0054] All captured data is used for the public security organ to master and analyze the actual people entering the room.

[0055] The screen set on the flat electronic device outside the door can be used as a carrier for publicizing the compliance room QR code. In addition, it can also display the entry advertisements and convenient information for life and tourism, sharing the economic pressure of the owner and facilitating the tourism life of the guests.

If the processor (1) determines that the door is open, the camera device (3) takes a video, and the processor (1) temporarily stores the real-time video data transmitted back by the camera device (3) in the memory (4); If the processor (1) determines that the door is not open, the camera device (3) only transmits the real-time video data to the processor (1), and the processor (1) determines whether there is anyone outside the door through the real-time video data transmitted back by the camera device (3); 2) If the processor (1) determines that there is someone outside the door, the camera device (3) takes a photo, and the processor (1) temporarily stores the photo data taken by the camera device (3) in the memory (4); If the processor (1) determines that there is no one outside the door, the process returns to step 1 again, and the processor (1) continues to determine whether there is anyone outside the door through the real-time video data transmitted back by the camera device (3); 3) After the camera device (3) takes a picture, the process returns to step 1, and the processor (1) continues to determine whether the door is open through the door opening and closing sensor device (2); If the person photographed by the camera device (3) leaves the photographing range of the camera device (3) before the processor (1) determines through the door opening and closing sensor device (2) that the door is open, the processor (1) deletes the photo data temporarily stored in the memory (4); 4) After the camera device (3) takes a picture, the processor (1) determines whether the door is closed through the door opening and closing sensor device (2). If the processor (1) determines that the door is closed, the camera device (3) stops shooting video; If the processor (1) determines that the door is not closed, the process returns to step 1 again, the camera device (3) continues to shoot video, and the processor (1) temporarily stores the real-time video data transmitted back by the camera device (3) in the memory (4); When the real-time video data temporarily stored in the memory (4) reaches the maximum capacity, If the camera device (3) has captured someone entering or leaving the room, the processor (1) automatically transmits the data temporarily stored in the memory (4) to the data system of the public security department through the communication device (5). While transmitting, the processor (1) immediately deletes the data in the memory (4) that has been transmitted, and the processor (1) continues to temporarily store the video data captured in real time by the camera device (3) in the memory (4); If the camera device (3) still does not capture anyone entering or leaving the room, the processor (1) automatically deletes the data temporarily stored in the memory (4), and the processor (1) continues to temporarily store the video data captured in real time by the camera device (3) in the memory (4); 5) When the camera device (3) stops filming, the processor (1) determines whether anyone enters or leaves the room based on the real-time video data sent back by the camera device (3). If the processor (1) determines that no one has entered or exited, the processor (1) deletes the data temporarily stored in the memory (4) and returns to step 1 again, and the processor (1) continues to determine whether the door is opened again through the door opening and closing sensor device (2); If the processor (1) determines that someone has entered the room, the processor (1) transmits the data temporarily stored in the memory (4) to the data system of the public security department through the communication device (5), and returns to step 1 again, and the processor (1) continues to determine whether the door is opened again through the door opening and closing sensor device (2); If the processor (1) determines that someone has left the room, the processor (1) determines whether there is someone outside the door through the real-time video data transmitted back by the camera device (3); 6) If the processor (1) determines that there is someone outside the door, the camera device (3) starts taking photos, and the processor (1) temporarily stores the photo data taken by the camera device (3) in the memory (4); If the processor (1) determines that there is no one outside the door, the processor (1) transmits the data temporarily stored in the memory (4) to the data system of the public security department through the communication device (5). After the processor (1) completes the data transmission through the communication device (5), the data temporarily stored in the memory (4) is deleted; 7) After the camera device (3) takes a photo, the process returns to step 5, and the processor (1) determines again whether there is anyone outside the door based on the real-time video data transmitted back by the camera device (3); 8) After the processor (1) transmits the data to the data system of the public security department, the process returns to step 1, and the processor (1) continues to determine whether the door is opened again through the door opening and closing sensor device (2).

8. The method for capturing a person entering a homestay room as claimed in claim 7, characterized in that: In the step 1), when the lock slot sensor A (6) does not detect a signal that the lock tongue is in the lock slot and the angle detector (8) detects that the door opening angle is greater than or equal to 30 degrees, the processor (1) determines that the door is in an open state.

9. The method for capturing a person entering a homestay room as claimed in claim 7, characterized in that: In the step 4), when the lock slot sensor A (6) detects a signal that the lock tongue is in the lock slot or the angle detector (8) detects that the door opening angle is 0 degrees, the processor (1) determines that the door is in a closed state.

10. The method for capturing a person entering a homestay room as claimed in claim 7, characterized in that: In the step 5), when the door is a left-opening door, if the person captured by the camera device (3) enters the picture from the right side of the picture and leaves the picture from the left side after passing through the door frame, then the processor (1) determines that someone has entered the room; if the person captured by the camera device (3) enters the picture from the left side of the picture and leaves the picture from the right side after passing through the door frame, then the processor (1) determines that someone has left the room; when the door is a right-opening door, if the person captured by the camera device (3) enters the picture from the left side of the picture and leaves the picture from the right side after passing through the door frame, then the processor (1) determines that someone has entered the room; if the person captured by the camera device (3) enters the picture from the right side of the picture and leaves the picture from the left side after passing through the door frame, then the processor (1) determines that someone has left the room.
