Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machine room access control, in particular to an integrated anti-theft face recognition access control system and method for bidirectional authentication. BACKGROUND

[0002] At present, there are important machine rooms in communication operators, power, commercial buildings and the like, and important servers, devices, networks and the like are running in the machine rooms, so the management of the machine rooms is particularly important. With the continuous development of access control technology, traditional card swiping access control and face recognition access control have been widely used, but these only meet the entry management and still cannot meet the full latitude management of the entry and exit of the machine rooms.

[0003] In related technologies, the existing single face card swiping access control only realizes the functions of face recognition or card swiping authentication for opening the door to enter, and the door is directly opened without authentication such as pressing an exit button inside the door when exiting, so that the personnel without authority can exit normally at any time and the personnel without authority cannot be detected when exiting. Meanwhile, the existing access control can only record the opening records and entry time of the personnel entering, and cannot record the exit records and exit time of the personnel.

[0004] In addition, in order to realize the authentication of the door inside and outside for opening the door, the existing technology needs to install face recognition card swiping access controls inside and outside the door respectively, and the two devices are managed separately, so that the device cost and installation and maintenance are doubled. The face recognition access control of the existing technology is basically matched with a magnetic lock or an electric lock, and such a lock has the problems of automatic unlocking when power failure and inability to use a key or other mechanical method to unlock. Once the access control device fails and there is no power failure, the door cannot be normally opened.

[0005] Therefore, there is an urgent need for an integrated anti-theft face recognition access control system and method for bidirectional authentication. SUMMARY

[0006] The present application aims to provide an integrated anti-theft face recognition access control system and method for bidirectional authentication, so as to realize the integrated access control structure design of the traditional split type face recognition access control and anti-theft access control.

[0007] In one aspect, the integrated anti-theft face recognition access control system for bidirectional authentication provided by the present application adopts the following technical solution: An integrated anti-theft face recognition access control system for bidirectional authentication, comprising an access control outer panel, an access control inner panel and an electric anti-theft lock body arranged between the access control outer panel and the access control inner panel, wherein the access control outer panel and the access control inner panel are both embedded with face recognition modules, and the two face recognition modules are connected with the electric anti-theft lock body at the same time. The face recognition module comprises a recognition frame, and a control mainboard and a face recognition camera are respectively arranged in the recognition frame.

[0008] Further, a door access card induction coil is arranged at the inner bottom of the recognition frame, and the door access card induction coil is connected with the control mainboard and the electric anti-theft lock body, and cooperates with a door access card carried by a relevant person.

[0009] Further, a loudspeaker mounting rack is arranged at the inner bottom wall of the recognition frame, and a loudspeaker is arranged in the loudspeaker mounting rack, and the loudspeaker is connected with the control mainboard, and a plurality of loudspeaker holes matched with the loudspeaker are arranged at the inner bottom wall of the recognition frame.

[0010] Further, a liquid crystal display screen is arranged at the middle part of the recognition frame, and the liquid crystal display screen is connected with the control mainboard; and a light supplementing lamp is arranged at the inner top of the recognition frame, and the light supplementing lamp cooperates with the face recognition camera and the liquid crystal display screen.

[0011] Further, an emergency mechanical device is arranged on the inner panel of the door access, and the emergency mechanical device is connected with the electric anti-theft lock body and the control mainboard, and a protection shell covering the outer side of the emergency mechanical device is arranged on the inner panel of the door access through a locking piece.

[0012] On the other hand, the application provides an integrated anti-theft face recognition door access method for bidirectional authentication, which adopts the following technical scheme: An integrated anti-theft face recognition door access method for bidirectional authentication, comprising an integrated face door access unlocking working principle and a bidirectional face recognition working principle. The integrated face door access unlocking working principle comprises the following steps: S1. When a person needs to enter or exit a machine room, a face recognition camera in a face recognition module photographs the person; S2. Then the face recognition camera sends the photographed picture to a control mainboard, and the control mainboard acquires the photographed picture in real time and analyzes it in real time, and extracts a face feature value when the face feature is analyzed; S3. The extracted face feature value is matched with a local storage face door opening permission feature value in similarity, and when the similarity is greater than 90%, it is determined that the face matching is successful, otherwise it is determined that the face matching fails; S4. When the face matching is successful, the validity of the face door opening permission validity period is verified, and if it is valid, the control mainboard sends an unlocking instruction to an electric anti-theft lock body, and finally the electric anti-theft lock body realizes unlocking after receiving the unlocking instruction. The working principle of the two-way face recognition includes the following steps: The outer panel and the inner panel of the access control are both embedded with face recognition modules, and both share a face recognition algorithm library, thereby realizing two-way face recognition for entering and leaving the door.

[0013] Further, the working principle of tailing personnel detection includes the following steps: When a person without access rights tails another person into the door and wants to leave, the person will break the protective shell on the emergency exit device, and then use the emergency exit device to control the electric anti-theft lock body to mechanically open the door. At the same time, the control mainboard obtains the emergency exit alarm signal in real time, and the access control automatically pushes the emergency exit alarm to the platform. The administrator immediately investigates the cause and determines whether it is a person without access rights who tails into the door.

[0014] Further, the working principle of door opening and closing state monitoring includes the following steps: After the electric anti-theft lock body outputs the door magnetic opening and closing state, the main tongue extension and retraction state, and the latch tongue extension and retraction state, the face recognition module can obtain the state signal data output by the electric anti-theft lock body in real time, and then transmit the state signal data to the control mainboard. The control mainboard controls the speaker to issue a door opening and closing warning sound to remind the person entering or leaving, thereby realizing door opening and closing state monitoring.

[0015] Further, the working principle of emergency power failure prevention includes the following steps: Since two-way face recognition is used to open the door, when the access control is powered off or dead, the face recognition module cannot be used, so that the door outside can be mechanically opened by the key and the electric anti-theft lock body, and the door inside can be opened by the emergency mechanical exit device, so as to prevent the door from being normally opened when the access control is powered off.

[0016] Compared with the prior art, the beneficial effects of the present application are: The scheme of the present application can be used in areas with high requirements for personnel access management, to realize two-way face recognition real-name system access management and record tracing, and can also be applied to the demand for staying time statistics of personnel entering and leaving. At the same time, it can effectively improve the investigation and handling of events of people without access rights tailing into the door.

[0017] In addition, through the structure of the integrated face recognition access control combined with the electric anti-theft lock body, the problem of automatic door opening caused by power failure of traditional face access control mortise locks and magnetic locks can be effectively solved, thereby enabling emergency mechanical unlocking in the case of improved safety, and further meeting the fire safety requirements.

[0018] In addition, through the high integration of the integrated face recognition access control, the construction cost of traditional two-way face recognition scene requirements can be effectively reduced. Attached Figure Description

[0024] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0025] On one hand, this application discloses an integrated anti-theft facial recognition access control system with two-way authentication for entry and exit, referring to... Figure 1 In this embodiment, the integrated facial recognition access control system for the computer room includes an outer access control panel 1, an inner access control panel 2, an electric anti-theft lock body, and a facial recognition module 3. The electric anti-theft lock body is installed between the outer access control panel 1 and the inner access control panel 2. This electric anti-theft lock body is a fully automatic lock body, capable of automatically locking the door after it is closed.

[0026] Furthermore, a lock slot 11 is installed on the outer panel 1 of the access control system. The lock slot 11 works in conjunction with the smart key held by the relevant personnel, and the lock slot 11 corresponds to the input end of the electric anti-theft lock body, so that the smart key can be inserted into the input end of the electric anti-theft lock body along the lock slot 11 to achieve mechanical unlocking and opening of the door.

[0027] To elaborate, this electric anti-theft lock body includes components such as a main control board, motor, main bolt, latch, door magnet, and sensors. When the main control board receives an unlocking command, it controls the motor to rotate and retract the main bolt, while simultaneously controlling the latch to be in the unlocked state. Finally, a person pulls the door handle to unlock the door. Closing the door occurs when the door magnet retracts. The main control board detects this retraction, indicating the door is closed. It then automatically controls the motor to reverse, extending the main bolt and locking the latch, thus locking the door. The main control board, motor, main bolt, latch, door magnet, and sensors are existing technologies and will not be described in detail here.

[0028] Meanwhile, there are two face recognition modules 3. The two face recognition modules 3 are installed in the outer panel 1 and the inner panel 2 of the access control system, respectively. The two face recognition modules 3 are also electrically connected to the electric anti-theft lock body, so that the face recognition module 3 can control the unlocking and locking of the electric anti-theft lock body.

[0029] This structure, which combines the facial recognition module 3 with the electric anti-theft lock, not only facilitates the implementation of two-way facial recognition real-name access management and record tracking in areas with high requirements for personnel access control, but can also be applied to the need for statistics on the length of time personnel stay from entry to exit. Moreover, it can effectively solve the problem of traditional facial recognition access control electric bolt locks and magnetic locks automatically opening when power is lost, thus improving security while also enabling emergency mechanical unlocking, thereby meeting fire protection requirements.

[0030] Specifically, refer to Figure 1 In this embodiment, the face recognition module 3 includes a recognition frame 31, a control motherboard 32, and a face recognition camera 33. The recognition frame 31 is installed on the outer panel 1 or the inner panel 2 of the access control system, and the front end of the recognition frame 31 is also equipped with tempered glass with a thickness of 2mm, which can protect other components inside the outer panel 1 or the inner panel 2 of the access control system.

[0031] Meanwhile, the control motherboard 32 is set inside the identification frame 31. As the control core of this system, the control motherboard 32 works in conjunction with the external platform. The control motherboard 32 is also electrically connected to the electric anti-theft lock body to control the opening and closing of the electric anti-theft lock body.

[0032] Preferably, in this embodiment, the control motherboard 32 is installed inside the identification frame 31 by a fastening assembly, and the fastening assembly includes multiple fastening screws and multiple fastening blocks installed on the inner walls of the identification frame 31. Each of the fastening blocks has a threaded hole that is threaded to connect with the fastening screws. Each of the four corners of the control motherboard 32 has a fastening hole that mates with the fastening screws. By passing the fastening screws through the fastening holes and then turning them into the threaded holes, the control motherboard 32 is securely installed inside the identification frame 31.

[0033] In addition, the face recognition camera 33 is also securely mounted on the inner top of the recognition frame 31 with multiple screws. The face recognition camera 33 can capture images of people entering and exiting. The face recognition camera 33 is electrically connected to the control motherboard 32, so that the control motherboard 32 can acquire the images captured by the face recognition camera 33 in real time, perform real-time analysis and extract facial feature values, and finally use the extracted feature values ​​to perform similarity matching with the locally stored face access permission feature values ​​to achieve the effect of face access control unlocking based on the similarity matching value.

[0034] Better, refer to Figure 1 In this embodiment, a liquid crystal display screen 4 is provided in the middle of the recognition frame 31. The liquid crystal display screen 4 is connected to the control motherboard 32 to display relevant information. A supplementary light 5 is also installed on the inner top of the recognition frame 31 by multiple screws. The supplementary light 5 works in conjunction with the face recognition camera 33 and the liquid crystal display screen 4. The supplementary light 5 is an LED light. In this way, the supplementary light 5 can provide additional light, thereby ensuring that the face recognition camera 33 or the liquid crystal display screen 4 can work normally and capture and display clear images.

[0035] In addition, in this embodiment, an access card induction coil 34 is installed at the bottom inner side of the identification frame 31. The access card induction coil 34 is electrically connected to the control motherboard 32 and the electric anti-theft lock body, and the access card induction coil 34 cooperates with the access card carried by the relevant personnel to sense each other.

[0036] When a person holding an access card approaches the access card induction coil 34, the control board 32 obtains the access card information in real time and matches it with the locally stored permission information. After matching, the control board 32 sends an unlocking command to the electric anti-theft lock body. Finally, after receiving the unlocking command, the electric anti-theft lock body controls the motor to rotate to realize the unlocking action.

[0037] Secondly, refer to Figure 1In this embodiment, an emergency mechanical device is also installed on the inner panel 2 of the access control system. This emergency mechanical device is interconnected with the electric anti-theft lock body and the control main board 32. A protective shell is also securely installed on the inner panel 2 via locking components. This protective shell seals and covers the outside of the emergency mechanical device to protect it. When the access control system experiences a power outage or malfunction, the face recognition module 3 will be unusable. In this case, the protective shell must be broken first, and then the door can be mechanically opened using the emergency mechanical device.

[0038] Specifically, the locking component consists of multiple locking blocks, which are installed on the opening side of the protective shell. Multiple locking holes are provided on the inner panel 2 of the access control system. The locking blocks are fixed and locked to each other with the locking holes, thereby making the protective shell securely installed on the outside of the inner panel 2 of the access control system.

[0039] Meanwhile, the emergency mechanical device includes an emergency mechanical knob 6 and a sensing device; wherein, the emergency mechanical knob 6 is installed on the inner panel 2 of the access control system, and one end of the emergency mechanical knob 6 is connected to the output end of the electric anti-theft lock body; thus, by rotating the emergency mechanical knob 6, the electric anti-theft lock body can be mechanically opened.

[0040] The sensor is installed inside the access control panel 2 and is electrically connected to the control board 32. To clarify, this sensor is existing technology and will not be elaborated upon here. When the emergency mechanical knob 6 drives the electric anti-theft lock to mechanically open the door, the sensor detects this information. The control board 32 then acquires this information in real time and pushes an emergency exit alarm signal to an external platform. Administrators can then immediately investigate the cause and determine if unauthorized personnel have followed the user in. This emergency mechanical device effectively improves the investigation and handling of unauthorized exit situations after unauthorized personnel have followed the user in.

[0041] Preferably, in this embodiment, a speaker mounting bracket 35 is also installed on the inner bottom wall of the identification frame 31, and a speaker 36 is installed in the speaker mounting bracket 35. The speaker 36 is electrically connected to the control motherboard 32 and the electric anti-theft lock body. Furthermore, a plurality of sound holes 37 are provided on the inner bottom wall of the identification frame 31, and these sound holes 37 cooperate with the speaker 36.

[0042] By setting up speaker 36, it can not only emit a prompt sound when the access control is opened or closed, but also emit a warning sound when the access control is not closed in time, and emit a corresponding warning sound when the access control is damaged.

[0043] On the other hand, this application also discloses an integrated anti-theft facial recognition access control method with two-way authentication for entry and exit. In this embodiment, the integrated facial recognition access control method for the computer room includes the working principle of integrated facial recognition access control unlocking and the working principle of two-way facial recognition.

[0044] The working principle of this integrated facial recognition access control system includes the following steps: S1. When personnel need to enter or exit the computer room, the face recognition camera 33 in the face recognition module 3 will capture images of the personnel.

[0045] S2. Then the face recognition camera 33 sends the captured image to the control motherboard 32. The control motherboard 32 then acquires the captured image in real time and performs real-time analysis. When facial features are detected, facial feature values ​​are extracted.

[0046] S3. Perform similarity matching between the extracted facial feature values ​​and the locally stored facial access permission feature values; if the similarity is greater than 90%, the face is considered to be successfully matched, otherwise the face is considered to be unmatched.

[0047] S4. After successful face matching, verify the validity period of the face access permission. If valid, the control board 32 sends an unlocking command to the electric anti-theft lock body. Finally, after receiving the unlocking command, the electric anti-theft lock body controls the motor to rotate and unlock.

[0048] Meanwhile, the working principle of this two-way facial recognition includes the following steps: By embedding facial recognition modules 3 in both the outer panel 1 and the inner panel of the access control system, and sharing a common facial recognition algorithm library, it is possible to achieve bidirectional facial recognition for both entry and exit. Specifically, this facial recognition algorithm library is existing technology, enabling both external and internal facial recognition to share the same whitelist database.

[0049] In addition, this integrated facial recognition access control method for the computer room also includes the working principles of tailgating detection, door opening / closing status monitoring, and emergency power outage prevention. The working principles of tailgating detection, door opening / closing status monitoring, and emergency power outage prevention are described in detail below: Specifically, the working principle of this tailgating detection system includes the following steps: When an unauthorized person follows another person into the door, they can leave by breaking the protective shell on the emergency exit device and then using the emergency exit device to control the electric anti-theft lock to mechanically open the door. At the same time, the control board 32 will receive the emergency exit alarm signal in real time. At this time, the access control will automatically push the emergency exit alarm to the platform, and the administrator can immediately investigate the cause and determine whether it is an unauthorized person who followed them in.

[0050] Meanwhile, the working principle of the door opening and closing status monitoring includes the following steps: when the electric anti-theft lock body outputs the door magnetic opening and closing status, the main tongue extension and retraction status, and the oblique tongue extension and retraction status, the face recognition module 3 can obtain the status signal data output by the electric anti-theft lock body in real time, and then transmit these status signal data to the control motherboard 32. The control motherboard 32 then controls the speaker 36 to emit a door opening and closing warning sound to remind people entering and exiting, thereby realizing the door opening and closing status monitoring.

[0051] In addition, the working principle of this emergency power outage protection includes the following steps: Because it adopts two-way facial recognition for entry and exit, the facial recognition module 3 will be unusable when the access control system experiences a power outage or malfunction. This allows the door to be opened mechanically from the outside using a key and an electric anti-theft lock, while the door can be opened from the inside using an emergency mechanical exit device. This ensures that normal entry and exit are possible even when the access control system is powered off.

[0052] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
