Description

Technical Field

[0001] This invention relates to the field of unmanned security, specifically to a facial recognition unmanned security device and its usage method. Background Technology

[0002] With the rapid iteration of artificial intelligence and Internet of Things technologies and the upgrading of consumer demand, unmanned self-service hotels have emerged rapidly due to their advantages such as no need for human staff, convenient check-in, and strong privacy. They are favored by consumers and have reduced the labor costs of hotel operations, becoming an important direction for the digital transformation of the hotel industry. However, "unmanned" operation also brings many security challenges, among which the security risks caused by tailgating and mixed traffic of people and goods are particularly prominent, seriously restricting its standardized development and promotion.

[0003] Currently, security measures in existing unmanned self-service hotels mainly rely on single facial recognition access control systems. These systems are primarily used to verify the identity of guests and open doors, and are not specifically designed to address issues such as tailgating and the mixing of people and goods in unmanned environments. In actual operation, during the brief opening of the access control after a guest's verification, unauthorized personnel can easily take the opportunity to tailgate and enter. This could not only illegally occupy hotel resources but also lead to theft and other illegal activities, threatening the personal safety and property of guests. This is the main security concern of current unmanned self-service hotels.

[0004] Meanwhile, the existing security system does not achieve separation of people and goods. When guests bring luggage and other items in and out, the system cannot effectively distinguish between people and goods. On the one hand, criminals may use goods to cover up their belongings and evade facial recognition, following legitimate people into the hotel. On the other hand, the unrestricted movement of goods can disrupt the hotel's public order and even create additional security risks due to the carrying of dangerous items or the stacking of goods.

[0005] Furthermore, mainstream facial recognition security technologies still have shortcomings: some devices have weak anti-spoofing capabilities and cannot resist forgery attacks such as photos and videos; most security systems focus on identity verification and lack real-time monitoring and early warning capabilities for suspicious behaviors such as tailgating; even though some hotels have introduced AI visual recognition algorithms, they have not optimized for core pain points such as people and goods mixed together and tailgating. At the same time, some devices have problems with insufficient encryption in facial data collection, transmission, and storage, posing a risk of privacy leakage, and have poor robustness, with recognition accuracy decreasing in complex scenarios, failing to meet the requirements for stable 24 / 7 operation.

[0006] In summary, the industry urgently needs a facial recognition-based unmanned security device that can separate people from goods, curb tailgating, and balance identity verification accuracy, privacy security, and operational stability. Therefore, developing a device and its application method adapted to the security needs of unmanned self-service hotels has significant practical importance and application value.

[0014] Furthermore, an emergency response component is fixedly installed above the conveying component. The emergency response component includes an upper connecting housing. A spring rewinding mechanism is rotatably installed inside the upper connecting housing. A barbed wire is wound on the spring rewinding mechanism. A tension rod is fixedly connected to the bottom end of the barbed wire. Connecting brackets for winding are installed at both ends of the spring rewinding mechanism. A lower connecting housing is provided below the tension rod. The lower connecting housing is fixedly installed on the conveying housing. A lower winding rod is rotatably installed inside the lower connecting housing.

[0015] Furthermore, a central rotating shaft is fixedly installed at both ends of the lower winding rod. A transmission ring is rotatably sleeved on the outside of the central rotating shaft. Multiple evenly distributed pressure springs are fixedly installed inside the transmission ring. A spherical head is fixedly installed on each pressure spring and slidably installed inside the transmission ring.

[0017] A facial recognition unmanned security method applicable to a facial recognition unmanned security device includes the following steps: S1: Customers place orders and complete facial recognition on their mobile devices, and the facial recognition component connects to the network to obtain the customer's facial information; S2: When a guest checks in, they use an external facial recognition device to verify their face. If the verification is successful, the facial recognition device controls the locking cylinder to work. The locking cylinder drives the lifting plate to move up, which in turn separates the gear plate from the transmission gear plate. The connecting shaft and the central column can rotate, and the guest pushes the barrier bar to enter the hotel. S3: After the customer has fully entered the interior, the infrared sensor triggers the control to reset the face recognition component. At this time, the gear plate will lock the emergency plan component, making the center column and the limit bar unable to rotate. S4: If the guest has large luggage such as a suitcase, the luggage can be placed on the conveyor when the face authentication is performed. Then, after the guest passes the face recognition, he pushes the barrier, and the luggage will be automatically moved through the device. S5: The device automatically closes after the luggage passes through it; S6: When guests need to leave the hotel, the same procedure is followed to place the luggage inside the conveyor component. When the customer leaves by scanning their face with the internal facial recognition component, the luggage will automatically be moved through the device. S7: The two facial recognition components communicate with each other. After a guest scans their face using the external facial recognition component and is shown as having passed once, they will no longer be able to enter the hotel by scanning their face using the external facial recognition component. They must leave the hotel by scanning their face using the internal facial recognition component before they can enter again by scanning their face using the external facial recognition component. S8: If the external facial recognition device completes the face scan, but the infrared sensor does not detect a person passing through within the specified time, the device will be turned off, and the guest can still enter the hotel by scanning their face with the external facial recognition device.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. By incorporating a conveying component, this device separates people and goods, effectively reducing tailgating and significantly increasing the safety of guests at unmanned self-service hotels; 2. This device, by setting up a conveyor tray and a horizontal slide, automatically transports luggage from the outside to the inside of the device as guests pass through, eliminating the need for guests to reach out and drag their luggage, greatly improving the check-in experience and passage efficiency; 3. This device is equipped with a barrier that only opens when a guest scans their face, and the barrier cannot be perceived as being pushed open, further increasing the device's security. 4. This device, by incorporating a tension rod, can quickly open a large passageway in special circumstances, allowing guests or police officers to pass through. This prevents situations where the person in charge cannot be found in the self-service hotel, thus delaying the response to an emergency and further enhancing security. 5. This device, by incorporating a transmission ring, can tension the tension rod whenever a guest passes by, ensuring that the large passageway remains closed under normal conditions even without maintenance, thus further enhancing safety and aesthetics.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-12 This invention provides a technical solution for a face recognition unmanned security device: it includes an entrance support 1, a one-way blocking frame 11 fixedly installed above the entrance support 1, a central column 2 rotatably installed between the entrance support 1 and the one-way blocking frame 11, a plurality of evenly distributed limit bars 21 fixedly installed on the central column 2, a conveying component 3 for luggage passage fixedly installed on one side of the entrance support 1, an emergency plan component 4 fixedly installed above the conveying component 3, buffer brackets 5 fixedly installed on both sides of the conveying component 3, a plurality of alarm lights 12 fixedly installed above the one-way blocking frame 11, an infrared sensor installed on the one-way blocking frame 11, and face recognition components 6 fixedly installed on both sides of the entrance support 1.

[0023] In actual use, guests place orders through a mobile client and undergo facial recognition verification. The system automatically recognizes the identity information and triggers access permissions. The external facial recognition component 6 connects to the network to obtain the guest's facial recognition data. When guests need to enter the hotel, they only need to undergo facial verification through the external facial recognition component 6. After successful verification, the central column 2 can rotate, and the guest can push the access barrier 21 to enter the hotel. If the verification fails, the central column 2 is locked and cannot rotate, and the access barrier 21 closes the entrance and exit. Because self-service hotels lack supervision, if the distance between the access barriers 21 is too large, it can easily lead to criminals tailgating. However, if the distance is too small, it can cause large luggage to get stuck, affecting passage efficiency. Therefore, if there is large luggage when passing through, the luggage can be placed on the conveyor component 3 before facial recognition. Then, the luggage is scanned and passes through the device. When passing through, the access barriers 21 and the central column 2 are pushed and rotated, which will drive the conveyor component 3 to automatically transport the customer's luggage through the device. In this way, the distance between the access barriers 21 can be precisely adjusted to allow only one person to pass through, which not only eliminates the risk of tailgating but also ensures the smooth passage of large luggage. When a customer needs to leave the hotel, they can verify their face through the internal facial recognition component 6 to push the central column 2 and the access barrier 21 to rotate and pass through the device, thus leaving the hotel. During the passage, luggage can be transported to the outside of the device simultaneously. The transport component 3 will only open after facial recognition is passed, and will remain closed at other times to prevent criminals from entering the hotel through the transport component 3.

[0024] A connecting shaft 13 is rotatably mounted on the passenger entrance support 1. The connecting shaft 13 is fixedly mounted on the lower end of the central column 2. A transmission gear 14 is fixedly mounted on the lower end of the connecting shaft 13. A drive sprocket 141 is fixedly mounted below the transmission gear 14. A lifting plate 15 is slidably mounted inside the passenger entrance support 1. The lifting plate 15 is slidably sleeved on the outside of the connecting shaft 13. A mating gear 151 is fixedly mounted on the lower surface of the lifting plate 15.

[0025] When facial recognition is successful, the locking cylinder 16 pushes the lifting plate 15 upward, causing the gear plate 151 and the transmission gear plate 14 to lose their engagement. When the limit bar 21 is pushed, the limit bar 21 will drive the central column 2 and the connecting shaft 13 to rotate. The connecting shaft 13 will drive the transmission gear plate 14 and the drive sprocket 141 to rotate synchronously. After the guest passes through the device, he is detected by the infrared sensor, and then the locking cylinder 16 will be controlled to reset. At this time, the lifting plate 15 descends and locks the transmission gear plate 14, thus preventing the connecting shaft 13, the central column 2, and the limit bar 21 from rotating.

[0026] The conveying component 3 includes a conveying housing 31. A conveying pallet 32 ​​is rotatably mounted in the middle of the conveying housing 31. Multiple evenly distributed second rotating rollers 321 are rotatably mounted on the conveying pallet 32. Multiple evenly distributed first springs 322 are fixedly connected between the conveying pallet 32 ​​and the conveying housing 31. Two transverse sliding plates 33 are slidably mounted inside the conveying housing 31. A center plate 334 is provided above the transverse sliding plates 33. The center plate 334 is fixedly mounted inside the conveying housing 31. A second spring 335 is fixedly mounted between the center plate 334 and the lifting block 333. Two symmetrical circular sliding plates 323 are fixedly mounted on both sides of the conveying pallet 32. The two transverse sliding plates 33 are located on both sides of the conveying pallet 32. Lifting blocks 333 are provided at both ends of the transverse sliding plates 33. A first groove 337 is provided on the lifting block 333. The circular sliding plates 323 are located inside the first groove 337.

[0027] When a guest passes through with luggage, the luggage is first placed on the conveyor tray 32, and then facial verification is performed. When the guest enters the device, the horizontal slide 33 moves outward. At this time, the circular slide 323 on one side will be lifted along the first slide 337 by the lifting block 333, and the circular slide 323 on the other side will be removed from the first slide 337. Then the conveyor tray 32 is rotated, changing to a state where the outside is higher and the inside is lower. The luggage on it will slide down to the inside of the device by gravity, and the guest can take the luggage directly. When guests need to leave the hotel, they place their luggage on the inside of the conveyor tray 32 and then undergo facial verification. The device then activates the reverse conveying mode, and the conveyor tray 32 rotates in the opposite direction, with the outer side lowering and the inner side rising. The luggage then slides to the outside of the device. After the guests leave, under the elastic force of the second spring 335, the lifting block 333 gradually returns to its initial state, and the conveyor tray 32 is moved to a horizontal position for the next guest to use.

[0028] A connecting frame 331 is fixedly connected between two transverse sliding plates 33. Two symmetrical levers 332 are fixedly installed below the connecting frame 331. A transmission sprocket 35 is provided below each of the two levers 332. The drive sprocket 141 and the transmission sprocket 35 are connected by a chain. An actuating plate 351 is fixedly installed on the upper surface of the transmission sprocket 35. The actuating plate 351 is located on one side of the conveyor tray 32. The two transmission sprockets 35 are connected by a chain.

[0029] The two transverse slides 33 are fixedly connected by a connecting frame 331 to ensure that they maintain synchronous displacement during movement, preventing them from shifting or tipping over when luggage slides down. When the passenger pushes the limit bar 21 and the center column 2 to rotate, the connecting shaft 13 drives the drive sprocket 141 to rotate. The drive sprocket 141 drives one of the transmission sprockets 35 to rotate via a chain. The two transmission sprockets 35 are also connected by a chain, thus achieving synchronous rotation of the two transmission sprockets 35. When the transmission sprocket 35 rotates, it drives the actuating plate 351 to rotate. The actuating plate 351 actuates the lever 332 to move, thereby causing the connecting frame 331 and the two transverse slides 33 to move synchronously.

[0030] Above each of the two horizontal sliding plates 33, there is a lifting sliding plate 34. A lifting bracket 36 is fixedly connected between the two lifting sliding plates 34. A rotating sleeve 37 is rotatably installed on the outside of the lifting bracket 36. A blocking member 371 is fixedly installed below the rotating sleeve 37. Limit blocks 372 are fixedly installed at both ends of the rotating sleeve 37. The conveying housing 31 has a slot that cooperates with the limit block 372. Side baffles 336 are fixedly installed on each of the two lifting blocks 333. A second slide groove 338 is opened on the side baffles 336. Slider blocks are fixedly installed at both ends of the lifting sliding plate 34. The sliders are located inside the second slide groove 338.

[0031] When no one is passing through, both ends of the lifting slide 34 are at the bottom of the lifting block 333. At this time, the limiting block 372 is locked in the slot of the conveying housing 31. The rotating sleeve 37 is locked by the limiting block 372 and the slot and cannot rotate. Thus, the blocking member 371 closes the channel in the middle of the conveying housing 31, ensuring the safe isolation of the channel. When the face recognition passes through, the passenger will drive the horizontal slide 33 to move when passing through the device. Then the lifting block 333 pushes the lifting slide 34 to move upward. The limiting block 372 is released from the slot, and the rotating sleeve 37 is unlocked and begins to rotate. The luggage pushes the blocking member 371 to rotate under the action of gravity. The side baffle 336 and the second slide 338 are designed so that the device cannot be unlocked by pushing the lifting slide 34 upward under normal conditions. This ensures that the rotating sleeve 37 can only disengage from the slot and start rotating after facial recognition is passed, thereby realizing the intelligent opening and closing of the channel and the precise linkage of baggage transportation.

[0032] The emergency response component 4 includes an upper connecting housing 41. A spring rewinding mechanism 42 is rotatably installed inside the upper connecting housing 41. A barbed wire 43 is wound on the spring rewinding mechanism 42. A tension rod 431 is fixedly connected to the bottom end of the barbed wire 43. Both ends of the spring rewinding mechanism 42 are equipped with connecting brackets 421 for winding. A lower connecting housing 44 is provided below the tension rod 431. The lower connecting housing 44 is fixedly installed on the conveying housing 31. A lower winding rod 45 is rotatably installed inside the lower connecting housing 44. Multiple evenly distributed connecting steel wires 432 are fixedly connected between the tension rod 431 and the lower winding rod 45.

[0033] During installation, the tension rod 431 is pulled and the connecting wire 432 is fixedly connected to the lower winding rod 45. At this time, the barbed wire 43 will close the passage below the upper connecting shell 41, and the connecting bracket 421 will be in its maximum tension state. Under normal circumstances, it is impossible to pass through the barbed wire 43. In case of fire or other emergencies, since it is an unmanned self-service hotel, when firefighters arrive, they may not be able to find the person in charge to open the door. In this case, firefighters can directly cut the connecting wire 432, and the connecting bracket 421 will quickly wind up the tension rod 431, opening a large passage below the upper connecting shell 41 for firefighters to pass through quickly for rescue. The device is also equipped with wire cutters. In case of fire, guests can also cut the tension rod 431 themselves to open the passage without having to scan the code one by one. This method is simple and quick, providing an early warning plan for unexpected situations.

[0034] Both ends of the lower winding rod 45 are fixedly mounted with a central rotating shaft 451. A transmission ring 46 is rotatably sleeved on the outside of the central rotating shaft 451. Multiple evenly distributed pressure springs 461 are fixedly mounted inside the transmission ring 46. A spherical head 462 is fixedly mounted on the pressure spring 461 and slidably mounted inside the transmission ring 46. Multiple spherical grooves 452 corresponding to the spherical heads 462 are opened on the central rotating shaft 451. Lifting housings 47 are provided on both sides of the central rotating shaft 451. A second slider 471 is slidably mounted inside one lifting housing 47, and a first slider 48 is slidably mounted inside the other lifting housing 47. The side of the second slider 471 closest to the central rotating shaft 451 is fixed. Multiple evenly distributed second ratchet teeth 472 are installed. Multiple evenly distributed third ratchet teeth 481 are fixedly installed on the side of the first slider 48 near the central rotating shaft 451. Multiple first ratchet teeth 463 that cooperate with the second ratchet teeth 472 are fixedly installed on the transmission ring 46. Multiple fourth ratchet teeth that cooperate with the third ratchet teeth 481 are fixedly installed on the central rotating shaft 451. Multiple evenly distributed third springs 473 are fixedly installed inside the lifting housing 47. A connecting support rod 474 is fixedly installed at the lower end of the lifting housing 47 corresponding to the second slider 471. The connecting support rod 474 is fixedly connected to the lifting bracket 36. The lifting housing 47 corresponding to the first slider 48 is fixedly installed inside the lower connecting housing 44.

[0035] During use, prolonged use may cause deformation of the tension rod 431, leading to loosening in some areas. This not only reduces safety but also detracts from the aesthetics. Therefore, each time a guest crosses the access barrier 21, the lifting bracket 36 is continuously raised and lowered. When the lifting bracket 36 rises, it drives the connecting rod 474 to rise. At this time, the second ratchet 472 on the connecting rod 474 pushes the first ratchet 463, causing the transmission ring 46 to rotate in one direction. Under the action of the spherical head 462 and the pressure spring 461, the lower winding rod 45 rotates. If the tension of the tension rod 431 is sufficient, the spherical head 462 will slide out from the inside of the spherical groove 452, and the lower winding rod 45 will not be driven to rotate. If the tension is insufficient, the spherical head 462 will be stuck in the spherical groove 452, driving the lower winding rod 45 to rotate, automatically tensioning the tension rod 431 to ensure that the passage is always reliably closed. When the lifting bracket 36 descends, it will drive the connecting rod 474 to descend. At this time, the third ratchet 481 and the fourth ratchet engage, locking the rewinding rod 45 in the reverse direction. The transmission ring 46 also cannot rotate in the reverse direction due to the resistance of the spherical head 462 and the spherical groove 452. Consequently, the second slider 471 will compress the third spring 473 and enter the interior of the lifting housing 47.

[0036] The buffer bracket 5 has a ramp inside near the conveying housing 31. Multiple evenly distributed first rotating rollers 51 are rotatably installed on the ramp. Multiple evenly distributed buffer pads 52 are fixedly installed on the side of the buffer bracket 5 away from the conveying housing 31.

[0037] When luggage passes through the device, it will first come into contact with the first rotating roller 51 on the ramp. The first rotating roller 51 increases the conveying speed of luggage and prevents luggage from piling up or getting stuck, which would affect the passage efficiency. The cushioning pad 52 can prevent luggage from being damaged by impact due to excessive movement speed.

[0038] A face recognition unmanned security method and a face recognition unmanned security device, comprising the following steps: S1: Customers place orders and complete facial recognition on their mobile devices. The facial recognition component 6 connects to the network to obtain the customer's facial information. S2: When a guest checks in, he / she uses an external facial recognition device 6 to verify his / her face. If the verification is successful, the facial recognition device 6 controls the locking cylinder 16 to work. The locking cylinder 16 drives the lifting plate 15 to move upward, and the gear plate 151 and the transmission gear plate 14 are separated. The connecting shaft 13 and the central column 2 can rotate, and the guest pushes the limit bar 21 to enter the hotel.

[0039] S3: After the customer has fully entered the interior, the infrared sensor triggers the control of the face recognition component 6 to reset. At this time, the gear plate 151 locks the emergency plan component 4, so that the center column 2 and the travel restriction bar 21 cannot rotate.

[0040] S4: If the guest has large luggage such as a suitcase, the luggage can be placed on the conveyor component 3 when performing facial recognition. Then, after the guest passes facial recognition, he pushes the limit bar 21 and the luggage will be automatically driven through the device. S5: The device automatically closes after the luggage passes through it; S6: When guests need to leave the hotel, the same procedure is followed to place the luggage inside the conveyor component 3. When the customer leaves by scanning their face with the internal facial recognition component 6, the luggage will automatically pass through the device.
