Description

Technical Field

[0001] The present invention relates to an access control device, and in particular to an intelligent access control device. Background Art

[0002] The intelligent access control security management system is a new type of modern security management system that integrates computer-based automatic identification technology with modern security management measures. It involves many new technologies such as electronics, mechanics, optics, computer technology, communications technology, and biotechnology. It is an effective measure to achieve security and prevention management at the entrances and exits of important departments.

[0003] At present, there are many ways to unlock the smart access control system, such as fingerprint unlocking, key password unlocking, face recognition unlocking or card swiping unlocking, etc. However, these unlocking methods are difficult to complete in certain circumstances. For example, fingerprint unlocking, card swiping unlocking and key password locking all require at least one hand to operate, that is, use one hand to enter the password, take out the access card, swipe the card and enter the fingerprint. However, if the entrant holds objects in both hands or holds an object in both hands at the same time, both hands or one of the hands cannot be unlocked. At this time, if you want to enter, you can only put down the object in your hand and then operate it. After the operation is completed, take it out again. The process of picking up items is interrupted, wasting a lot of time. Furthermore, dust on the ground easily sticks to items, so the entire process has certain drawbacks. When these problems occur, the only effective solution is facial recognition unlocking. However, with the prevalence of masks, people often wear masks when traveling and returning home. Without both hands free, it is difficult to remove the mask for facial recognition. This also requires at least one hand to unlock the mask. Even if both hands are available, facial recognition is greatly affected by the environment. Ambient lighting, the person's weight, and the clarity of the camera lens can all affect facial recognition accuracy. Therefore, a new access control unlocking system with an uninterrupted process is urgently needed.

[0004] In addition, the existing access control equipment is an integrated fixed structure. When installed, it is embedded in the wall, exposing a control panel on which a display screen, a card swiping area, a fingerprint reader, a face recognition camera and a numeric keypad are set. The setting state of these components is basically completely exposed. In many cases, we only need to select one of them to unlock, so these unused components do not need to be exposed frequently. Long-term exposure to the environment has a greater impact on the numeric keypad and fingerprint reader, and the usage rate of the numeric keypad and fingerprint reader is lower than that of face recognition and card swiping. When the numeric keypad is exposed to the external environment, dust easily accumulates and water vapor is more likely to enter. The service life of the numeric keys of the access control used outdoors is often shorter, and the fingerprint reader is more affected by dust, which often leads to a low fingerprint recognition rate. Therefore, the usage rate of these two methods is significantly lower than that of access control card swiping and face recognition.

[0005] In addition, when the card swiping area is in use, the user uses the access card to unlock the access control by swiping it close to or touching it. However, since some access cards are made of hard materials, people often swipe the access card and rub it against the card swiping area to swipe it. At this time, the entire card swiping area cannot move away, resulting in hard contact between the hard access card and the surface of the card swiping area. Over time, the position of the access card swiping area will be severely worn, and the access card will also be more or less worn, resulting in malfunction. The directly fixed display screen is also more likely to be damaged by impact. Summary of the Invention

[0027] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0028] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0029] like Figure 1-Figure 2 As shown, an intelligent access control device of the present invention includes an access control body embedded in a wall, wherein the access control body includes a shell 1, a movable cavity 5 is provided on the front face of the shell 1, a movable panel 15 is provided in the movable cavity 5, a control motherboard and a power supply are built in the movable panel 15, the power supply is connected to the mains, a display screen 22 is provided on the outer side face of the shell 1, a pressure detection component is provided on the bottom face of the movable cavity 5, a signal output end of the pressure detection component is connected to the control motherboard and the pressure value is displayed through the display screen 22, an auxiliary pressure access control system is provided on the front face of the movable panel 15, the inner side face of the movable panel is in contact with the outer side face of the pressure detection component, and the access control system is unlocked by applying pressure to the pressure detection component through the auxiliary pressure access control system.

[0030] like Figure 1 、 Figure 3 As shown, the auxiliary pressure access control system includes a retaining ring 21, with an active cavity 24 opened in the middle of the retaining ring 21, a driving plate 16 is arranged in the active cavity 24, and an outwardly protruding pressure confirmation button is arranged on the inner wall surface of the active cavity 24. The human elbow contacts the driving plate and makes the driving plate 16 squeeze and contact with the pressure confirmation button on either side. By applying pressure to the pressure confirmation button, the pressure value detected by the pressure detection component is confirmed.

[0031] like Figure 5 As shown, there are four pressure confirmation buttons, which are arranged at the top middle position, bottom middle position, left middle position and right middle position of the active cavity of the retaining ring 21.

[0032] Among them, the pressure confirmation buttons include a confirmation button 25 and a corresponding pressure sensor 26. The pressure sensor 26 is mounted on the outer end face of the confirmation button 25. The inside of the retaining ring is hollow, and a key board is set at the position of the corresponding confirmation button. Each key board is connected to the control main board. Each group of pressure confirmation buttons corresponds to a number. The signal output end of each pressure sensor and confirmation button is connected to the control main board, and the control main board detects the pressure confirmation button with the corresponding number.

[0033] In this embodiment, there are four groups of pressure confirmation buttons, which are located in the four directions of up, down, left and right of the retaining ring. In this way, when the driving plate moves in any direction of up, down, left or right, it is regarded as controlling one group of pressure confirmation buttons, and is also regarded as pressure confirmation in that direction.

[0034] like Figure 1 and Figure 4 As shown, a gap cavity is formed between the outer wall surface of the driving plate 16 and the inner wall surface of the active cavity of the retaining ring 21. An elastic connecting column 23 is provided at each of the four corner positions on one side of the driving plate 16 relative to the bottom surface of the active cavity 24. The other end of the elastic connecting column 23 is fixedly bonded to the bottom surface 24 of the active cavity. The driving plate is controlled by the human elbow to move toward the pressure confirmation buttons at the upper and lower ends and the left and right ends. The elastic connecting column 23 is made of an elastic rubber material with deformation recovery ability. Therefore, the driving plate 16 can be deformed within a certain range so that it can be close to the pressure confirmation button. After the force is removed, the driving plate is reset, and the pressure value detected by the pressure detection component is confirmed through the pressure confirmation button and the number of the pressure sensor is confirmed.

[0035] In order to facilitate contact with the human elbow, a convex plate 19 is provided on the outer side of the driving plate. In order to better apply force to the driving plate to move in different directions, a positioning cavity 17 is provided on the convex plate, and the human elbow contacts the positioning cavity. The convex plate is made of rubber material to increase the softness when in contact with the elbow.

[0036] like Figure 3As shown, the pressure detection component includes a fixed seat 2 arranged on the bottom surface of the movable cavity 5, an ejection spring is arranged in the fixed seat 2, the outer end of the fixed seat 2 is telescopically inserted into a movable block 8, and a guide slide 6 is arranged on the upper and lower sides of the movable block 8. The movable block 8 and the fixed seat 2 are guided to slide through the guide slide 6. The inner end of the movable block 8 is fixedly bonded to the ejection spring (not shown), and a pressure main sensor 12 is fixedly bonded to the outer end of the movable block 8. One end of the pressure main sensor 12 is in contact with the inner side of the movable panel. The pressure main sensor 12 is connected to the control main board in the movable panel 15 through the power signal line 3. The pressure value detected by the pressure main sensor is displayed on the display screen.

[0037] The specific principles are as follows:

[0038] The main pressure sensor mainly detects the pressure value applied by the human body on the movable panel. The greater the pressure, the greater the pressure applied by the movable panel to the main pressure sensor, and the greater the pressure on the ejection spring. This pressure value is directly displayed on the display screen, that is, each user sets the pressure value to be reached through the access control terminal. The pressure value can be several groups, such as the first group of pressure values ​​is set to 507, and the second group of pressure values ​​is set to 720. Of course, more groups of pressure values ​​can be added according to the security level. However, in order to improve the unlocking speed while ensuring security, it is best to set two groups of pressure values. The more groups are set, the more confirmation steps are required;

[0039] In order to further improve security and shorten the verification cycle, the present invention sets four groups of pressure confirmation buttons on the upper, lower, left and right sides. The four groups of pressure confirmation buttons represent secondary verification and can also be used to confirm the pressure value of the display screen. The pressure confirmation buttons include a confirmation button and a corresponding pressure sensor. The pressure sensor here is used for orientation confirmation, not for pressure detection. The upper pressure sensor is set to number 1, the lower pressure sensor is numbered 2, the left pressure sensor is numbered 3, and the right pressure sensor is numbered 4. The confirmation button here has the same number as the corresponding pressure sensor. Assuming that the resident sets the access control opening value group as: 507, left pressure confirmation button, 720, right pressure confirmation button, the correct operation process is as follows:

[0040] like Figure 6 As shown, the user sets the value group for opening the access control through the mobile client, such as "507, left pressure confirmation button, 720, right pressure confirmation button". After the setting is completed, the server saves and stores the data group, and the signal transmission module communicates wirelessly with the server. When the user enters the house, he only needs to operate according to the above-set values ​​to unlock the access control and achieve the purpose of entering the house.

[0041] Specifically, when the user's hands cannot be freed, the user buckles the elbow into the positioning cavity and uses the elbow to press down the movable panel. At this time, the movable panel pushes the movable block after being pressed. The back of the movable panel will first contact the main pressure sensor, and a pressure value will be generated at this time. The size of the pressure value is displayed on the display screen. After continuously applying force to the movable panel, when the value on the display screen shows any value between 501-599, the default pressure value is equal to 507. Using the interval value to confirm the value can improve operation efficiency. If the display screen shows "507" accurately, it is difficult to control and takes a lot of time. Therefore, the value confirmation here only needs to enter the interval value to be considered as the same value. When the value on the display screen shows any value between 501-599, the elbow maintains pressure and pushes the driver board toward the left pressure confirmation button. When the driver board contacts the pressure sensor of the left pressure confirmation button, the number information corresponding to the pressure sensor is transmitted to the control main board. Finally, the confirmation button on the left is pressed to confirm the pressure value at the main pressure sensor. The above is the first verification. Regardless of whether the above verification is correct, a second verification is required.

[0042] During the second verification, the pressure value displayed on the control display screen is between 701-799. At this time, the elbow is used to control the drive board to move toward the pressure confirmation button on the right, and finally contact the right pressure sensor and press the confirmation button on the right to complete the second verification. The entire system then compares the database to see if there is a corresponding data group corresponding to the above operation. If the database does, it can verify that the operator is the user. At this time, the access control is unlocked through the action execution module. If the database does not have it, it is deemed that the operator does not have the entry right and the access control status remains.

[0043] Since the entire verification is divided into two verifications, and each verification has direction verification, there are many combinations in the entire verification process. The number of users in a building only accounts for a small part of the data group. The probability of repetition is very low, and the probability of being guessed is also very low, so security is sufficiently guaranteed.

[0044] Please continue reading Figure 3 A slightly convex numeric keypad 11 is provided on the bottom surface of the movable cavity 5, and a fingerprint identifier 7 is provided on any side of the movable cavity 5. The identification mirror of the fingerprint identifier 7 is slightly convex on the side of the movable cavity. Grooves are provided on the upper, lower, left and right four surfaces of the movable panel 16, and cleaning cotton strips (not shown) are embedded in the grooves. The cleaning cotton strips are in contact with the surface of the numeric keypad 11 and the fingerprint identifier 7. The numeric keypad 11 and the fingerprint identifier 7 are connected to the control main board in the movable panel through the power signal line after being routed from the inside of the shell.

[0045] The movable panel 15 is further provided with guide sliders 14 on the upper, lower, left and right sides. A guide slot 4 is provided in the movable cavity facing the guide slider 14. The guide slider 14 and the guide slot 4 enable the movable panel to be smoothly guided when being pushed.

[0046] The bottom surface of the guide groove is provided with a return spring (not shown), one end of the return spring is fixedly bonded to the bottom surface of the guide groove 4, and the other end of the return spring is fixedly bonded to one side surface of the guide slider. The return spring is used to return the movable panel to the bottom surface and make the outer side surface of the movable panel slightly convex from the front end surface of the shell. When the movable panel is pushed inward, the return spring is compressed. After the movable panel is released, the return spring pushes the movable panel to return outward.

[0047] Among them, the display screen 22 is located at the top of the auxiliary pressure access control system. An anti-peeping film is affixed to the display screen 22 to prevent outsiders from seeing the pressure value. A face recognition camera 13 is set on the movable panel at the upper end of the display screen, and a card reader 18 is set at the bottom of the auxiliary pressure access control system. The card reader 18 and the face recognition camera 13 are both connected to the control motherboard and powered by a power supply. Since the card reader is located on the movable panel, when the access card contacts the card reader, if there is a large contact force, the movable panel can be retreated to achieve the purpose of buffering and retreating to prevent excessive collision and friction.

[0048] The beneficial effects of the present invention are as follows: First, the present invention divides the access control into two main bodies, sets the access control unlocking structure separately, and hides the fingerprint reader and the numeric keypad. In this way, when the movable panel is pushed and squeezed back and forth, the cleaning cotton strips on the outer side of the movable panel can contact the fingerprint reader and the numeric keypad to achieve surface cleaning, so that the fingerprint reader and the numeric keypad are always in a clean state, ensuring the recognition success rate of the fingerprint reader and improving the waterproof and dustproof capabilities of the numeric keypad;

[0049] Second, the card swiping area is set on the movable panel, so that the contact between the access card and the card swiping area becomes buffered, reducing the impact between the two, extending the service life and reducing wear; the display screen is set on the movable panel, making the display screen more impact-resistant, increasing the display screen's buffering capacity and improving safety when used outdoors;

[0050] 3. When both hands cannot be freed, the present invention utilizes the human elbow to contact the positioning cavity, and applies pressure to the pressure detection component through the auxiliary pressure access control system to unlock the access control system. The purpose of quickly opening the access control is achieved through the pre-set values ​​of the platform, unlocking a new access control opening method, rationally utilizing the position of the human elbow, and can smoothly open the access control even when both hands cannot be freed. There is no interruption in the intermediate process, which is more convenient for people's lives.

[0051] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
