[0036] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In one embodiment of the present invention, in order to facilitate the use of Bluetooth access control, the present invention provides a control method based on Bluetooth network access control, comprising the following steps:

[0038] S1. When approaching the access control through the user device, the user device will establish a connection with the Bluetooth card reader 2 on the access control machine 1; first install the Bluetooth network access control host in a suitable position near the door, ensure that it is firmly installed and easy to wire and connect to the power supply, then install door locks, door magnets and other supporting equipment as needed, and connect the access control host to the network at the same time, configure network parameters such as IP address, subnet mask, gateway, etc., to ensure that it can access the local area network or the Internet normally;

[0039] Then, in the access control system management software, register the Bluetooth card or mobile device that supports Bluetooth function, enter relevant information such as card number, user name, contact information, etc., and bind it with the corresponding access control authority to determine which doors and time periods the Bluetooth card or device can open.

[0040] Next, before use, users need to ensure that the Bluetooth function of their mobile devices is turned on. For devices used for the first time, they may need to be paired with the access control system. In the access control system management software, follow the prompts. Generally, search for nearby Bluetooth devices on the mobile device, find the corresponding access control Bluetooth device and pair it. After pairing is successful, the device will automatically save the relevant information and there is no need to pair it again for subsequent use.

[0041] S2, when the Bluetooth card reader 2 sends the received information to the central management system, it determines whether the user has the right to enter the designated area according to the preset access control policy; when the user arrives near the access control, he opens the corresponding access control APP or performs specific operations on the mobile device, such as clicking the door opening icon, etc., to send a door opening request to the access control system. At this time, the mobile device will send the request signal to the nearby Bluetooth network access control host through the Bluetooth communication protocol;

[0042] When the Bluetooth network access control host receives the door opening request signal sent by the user device, it first receives and parses the signal to obtain the user identity information, etc. Then, it compares and verifies the information with the registered user information in the system to check whether the user has the right to open the door and whether the current time is within the time period allowed by his authority.

[0043] S3. If the user is authorized to access, the central management system will send a control instruction to the Bluetooth card reader 2, so that the access control machine 1 executes the control instruction to unlock the door; when the user identity verification is passed and has the right to open the door, the access control host will parse and send a door opening instruction to the door lock to control the door lock to open. At the same time, the system will record the operation logs such as the door opening time and user information for subsequent query and statistics. If the verification fails, the access control host will not send the door opening instruction, and may send a prompt message to the user through the prompt device of the access control system, such as a speaker or a display screen, to inform the user of the reason for the failure to open the door;

[0044] When the door lock receives the door opening command from the access control host, the internal mechanical or electronic device drives the lock core to open the door, and the user can push the door to enter;

[0045] After the user passes through the door, the door will automatically close under the action of the door closer. The Bluetooth access control system also has an automatic locking function. When the door is closed, the door lock will automatically re-lock to ensure the safety of the door. At the same time, the access control system will continue to monitor the status of the door, such as whether the door is opened abnormally, and send alarm information to the management personnel in time.

[0046] In the second embodiment of the present invention, a Bluetooth card reader 2 is installed on the surface of the access control machine 1, an anti-collision structure 3 is installed on the side of the access control machine 1, an anti-rotation structure 4 is arranged on the side of the anti-collision structure 3 close to the access control machine 1, and an anti-pinch structure 5 is arranged inside the access control machine 1;

[0047] When the anti-collision structure 3 is hit, the anti-collision structure 3 shrinks inward to cushion the impact and drives the anti-rotation structure 4 away from the anti-collision structure 3 to prevent it from rotating. At the same time, the anti-rotation structure 4 drives the anti-clamping structure 5 to move closer to each other to clamp the anti-collision structure 3 firmly.

[0048] The present invention takes into account that when the existing access control is installed in an office building, there are many office workers in the office building. Therefore, when the office workers are late, they may break through the card or tailgate. If the office workers break through the card, they may hit the door of the access control, causing damage to the door of the access control or causing personal injury to the office workers. Therefore, when the anti-collision structure 3 is hit, the anti-collision structure 3 will shrink inward to buffer the impact force of the person hitting the anti-collision structure 3, which can not only protect the anti-collision structure 3, but also protect the personal safety of the personnel, thereby reducing the damage caused by the anti-collision structure 3 to the personnel;

[0049] Furthermore, considering that when an unlocked access control door is hit, the access control door will be rotated by the impact force of the person breaking into the door, making the access control door loose or losing its original function, therefore, the contraction process of the anti-collision structure 3 will drive the two anti-rotation structures 4 to move away from each other and engage with each other, so that when the anti-collision structure 3 is hit, the anti-rotation structure 4 is engaged to restrict the anti-collision structure 3 from rotating, and when the anti-rotation structures 4 move away from each other, the two anti-clamping structures 5 will be driven to move closer to each other to clamp the anti-collision structure 3 when it is hit. By providing dual protection of engaging and clamping the anti-collision structure 3, the anti-collision structure 3 can be effectively prevented from rotating when it is hit, thereby increasing the service life of the anti-collision structure 3.

[0050] First, to realize the normal function of access control machine 1, please refer to Figure 1-Figure 4 The anti-collision structure 3 at least includes a rotating shaft 34, which is rotatably connected to the inside of the access control machine 1, and a switch door 31 is fixedly connected to the outer ring surface of the rotating shaft 34. A motor 35 is fixedly connected to the bottom of the rotating shaft 34, and the motor 35 is fixedly connected to the inside of the access control machine 1. The motor 35 is electrically connected to the Bluetooth card reader 2. When a person approaches the access control machine 1, an instruction is input through a mobile device and transmitted to the central management system through the Bluetooth card reader 2. After analysis, the output shaft of the motor 35 is started to rotate, and the rotating shaft 34 is driven to rotate, and then the switch door 31 is driven to swing and open, thereby realizing the normal opening function of the access control machine 1, which is convenient for subsequent personnel to enter and exit.

[0051] The detailed structure of the improved point of the present invention is as follows:

[0052] To achieve anti-collision of the door 31 and reduce the damage to the access control machine 1, the structure of the anti-collision structure 3 needs to be disclosed in detail. Please refer to Figure 1-Figure 4 The anti-collision structure 3 at least includes a spring 33, which is fixedly connected to the inside of the switch door 31. The end of the spring 33 away from the switch door 31 is fixedly connected to an anti-collision plate 32. A plurality of springs 33 are arranged between the anti-collision plate 32 and the switch door 31. When a person accidentally hits the switch door 31, the impact force will first contact the anti-collision plate 32, and then drive the spring 33 to compress, thereby buffering the impact force of the person's impact and reducing the damage to the switch door 31. At the same time, it can also reduce the harm to the personal safety of the personnel and improve the safety of the use of the switch door 31.

[0053] At the same time, in order to prevent the switch door 31 from accidentally rotating when it is hit, if no protection is provided, the switch door 31 may lose its original function. The structure of the anti-rotation structure 4 is disclosed in detail. Please refer to Figure 2-Figure 8The anti-rotation structure 4 includes at least two first wedge blocks 41 and two second wedge blocks 42. The two first wedge blocks 41 are fixedly connected to the side of the anti-collision plate 32, and the two second wedge blocks 42 are slidably connected to the inside of the switch door 31. The two first wedge blocks 41 and the inclined surfaces of the two second wedge blocks 42 are adapted to each other. Two clamping shafts 43 are fixedly connected to the sides of the two second wedge blocks 42. Both of the two clamping shafts 43 are slidably connected to the rotating shaft 34 and the switch door 31. Two clamping blocks 44 are arranged at the ends of the two clamping shafts 43. The two clamping blocks 44 are respectively fixedly connected to the surface of the motor 35 and the inside of the access control machine 1. When the anti-rotation structure 4 When the impact plate 32 moves to buffer the impact force, it will drive the spring 33 to compress, and at the same time drive the two first wedge blocks 41 to move toward the second wedge block 42, and squeeze the two second wedge blocks 42 to move away from each other. Then, the movement of the two second wedge blocks 42 will drive the two clamping shafts 43 to slide on the surface of the switch door 31 and the rotating shaft 34, so that the two clamping shafts 43 will be respectively clamped with the two clamping blocks 44, and then the rotating shaft 34 can be limited to prevent it from rotating, thereby preventing the switch door 31 from accidentally rotating around the center of the rotating shaft 34 when a person hits the switch door 31, thereby further improving the service life of the switch door 31.

[0054] In order to describe the positional relationship between the anti-collision structure 3 and the anti-rotation structure 4, and to facilitate understanding of the above working principle, please refer to Figure 1-Figure 8 When the anti-collision plate 32 is in a state of being retracted inside the switch door 31, the first wedge block 41 fixedly connected to the side of the anti-collision plate 32 will be squeezed by the second wedge block 42 slidably connected to the switch door 31; when the anti-collision plate 32 is in a state of not being retracted inside the switch door 31, the first wedge block 41 fixedly connected to the side of the anti-collision plate 32 will not contact the second wedge block 42 slidably connected to the switch door 31;

[0055] When the second wedge block 42 is in a state of being squeezed by the first wedge block 41, the clamping shaft 43 fixedly connected to the side of the second wedge block 42 is in a state of being mutually clamped with the clamping block 44. When the second wedge block 42 is in a state of not being squeezed by the first wedge block 41, the clamping shaft 43 fixedly connected to the side of the second wedge block 42 is in a state of not being mutually clamped with the clamping block 44.

[0056] Next, in order to further protect the rotating shaft 34 from accidental rotation, the structure of the anti-pinch structure 5 needs to be disclosed in detail. Figure 9-11The anti-pinch structure 5 includes at least two second pin shafts 55, and the two second pin shafts 55 are rotatably connected to the outer ring surfaces of the two clamping shafts 43 respectively. The outer ring surfaces of the two second pin shafts 55 are fixedly connected to two swing rods 51 respectively. The two swing rods 51 are rotatably connected to the two first pin shafts 52 on the side away from the two second pin shafts 55, and the outer ring surfaces of the two first pin shafts 52 are fixedly connected to two clamping plates 53 respectively. When the two clamping shafts 43 move away from each other and are clamped with the two clamping blocks 44, the two second pin shafts 55 will be synchronously driven to move away from each other. At the same time, the two swing rods 51 will be synchronously driven to swing towards each other, so that the two first pin shafts 52 and the two clamping plates 53 on the side of the two swing rods 51 away from the two second pin shafts 55 will move towards each other, so that the two clamping plates 53 can clamp the two sides of the switch door 31 when they are close to each other, thereby further clamping and protecting the switch door 31 when it rotates accidentally.

[0057] In order to describe the positional relationship between the anti-rotation structure 4 and the anti-pinch structure 5, and to facilitate understanding of the subsequent working principle, please refer to Figure 9-11 When the two clamping shafts 43 slidably connected to the outer annular surface of the rotating shaft 34 are moving away from each other, the second pin shafts 55 rotatably connected to the outer annular surfaces of the two clamping shafts 43 are moving away from each other. When the two second pin shafts 55 are moving away from each other, the two swinging rods 51 fixedly connected to the outer annular surfaces of the two second pin shafts 55 are swinging towards each other. When the two swinging rods 51 are swinging towards each other, the clamping plates 53 fixedly connected to the outer annular surfaces of the two first pin shafts 52 are clamping the rotating shaft 34.

[0058] When the two clamping shafts 43 slidably connected to the outer annular surfaces of the rotating shaft 34 are approaching each other, the second pin shafts 55 rotatably connected to the outer annular surfaces of the two clamping shafts 43 are approaching each other. When the two second pin shafts 55 are moving away from each other, the two swinging rods 51 fixedly connected to the outer annular surfaces of the two second pin shafts 55 are swinging away from each other. When the two swinging rods 51 are swinging away from each other, the clamping plate 53 fixedly connected to the outer annular surfaces of the two first pin shafts 52 is in a state of not clamping the rotating shaft 34. The outer annular surface of the first pin shaft 52 is fixedly connected with a fixing block 54. When the two second pin shafts 55 are reset and move closer to each other, , which will drive the two swing rods 51 to swing away from each other, so that the two swing rods 51 are respectively away from the two first pin shafts 52 on one side of the second pin shaft 55 and the two clamping plates 53 and move away from each other until they abut against the inside of the access control machine 1, so that the two clamping shafts 43 rotatably connected with the two second pin shafts 55 are respectively reset and restricted to be immobile, thereby facilitating the subsequent normal use of the switch door 31, and when the switch door 31 swings open normally, the side of the switch door 31 will be clamped with the fixing block 54 to prevent the switch door 31 from resetting immediately after opening, thereby reducing the personal injury caused by the reset and clamping of the switch door 31 to the people passing by.

[0059] In summary, the overall working principle of the present invention is as follows:

[0060] After a person pairs with the Bluetooth card reader 2 through a mobile device, when the person approaches the access control machine 1, he inputs a command (such as opening the access control) through the mobile device and transmits it to the central management system through the Bluetooth card reader 2. After the analysis and comparison are correct, the output shaft of the motor 35 will be started to rotate, and the rotating shaft 34 will be driven to rotate, and then the switch door 31 will be driven to swing and open, thereby realizing the normal opening function of the access control machine 1.

[0061] When a person accidentally hits the switch door 31, the impact force will first contact the anti-collision plate 32, and then drive the spring 33 to compress, thereby buffering the impact force of the person's impact. At the same time, it can also reduce the harm to the personal safety of the person. Then, the movement of the anti-collision plate 32 will also drive the two first wedge blocks 41 to move and squeeze the two second wedge blocks 42 to move away from each other, and then drive the two clamping shafts 43 to slide on the surface of the rotating shaft 34, so that the two clamping shafts 43 will be respectively clamped with the two clamping blocks 44, and then the rotating shaft 34 can be limited to prevent it from rotating, thereby preventing the switch door 31 from accidentally rotating around the center of the rotating shaft 34 when it is hit.

[0062] At the same time, when the two clamping shafts 43 move away from each other and are clamped with the two clamping blocks 44, the two second pin shafts 55 will be synchronously driven to move away from each other, and then the two swing rods 51 will be driven to swing towards each other, so that the two first pin shafts 52 and the two clamping plates 53 will move towards each other, thereby achieving the clamping of the two sides of the switch door 31 when the two clamping plates 53 approach each other.

[0063] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
