Description

Technical Field

[0001] This invention relates to the field of multimodal biometric unlocking technology, specifically to a multimodal biometric unlocking device and unlocking method for lockers at mine entrances. Background Technology

[0002] The multimodal biometric unlocking device for mine shaft lockers is an intelligent lock system that integrates multiple biometric technologies. Designed for use in mine shaft lockers, it uses iris, face, and cortical recognition technologies to detect and identify personnel identity information, determine personnel identity, and upload the information to the system database. This device can meet the needs of mining enterprises in daily changing room management, such as adding locker equipment, setting equipment parameters, viewing the current locker usage status (including the number of locker doors, the number of locker doors used and unused, and the information of the personnel bound to the locker doors), and remote unlocking by administrators. It is linked with biometric identification equipment to ensure that employees can quickly and accurately open the locker when storing and retrieving clothing. At the same time, it can also detect the temperature, humidity and odor indicators inside the locker in real time, and automatically turn on and off the intelligent modules such as disinfection, sterilization, deodorization and ventilation, effectively improving the working environment of miners and enhancing the comfort of changing rooms in coal mine bathrooms. Existing multimodal biometric unlocking devices installed in mine shaft lockers rely on iris recognition. Dust buildup on the surface of these devices can cause recognition failures. Simply cleaning with a brush or roller can lead to dust getting stuck between the brush / roller and the iris recognition device, potentially scratching it during the cleaning process. Therefore, this paper proposes a multimodal biometric unlocking device and unlocking method for mine shaft lockers to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a multimodal biometric unlocking device and method for lockers at mine entrances, in order to solve the problem that existing multimodal biometric unlocking devices installed in mine entrance lockers, which rely on iris recognition, are prone to recognition failure due to dust adhering to the surface of the iris recognition device. Simply cleaning with a brush or roller can prevent dust from getting stuck between the brush or roller and the iris recognition device, thus avoiding scratching the iris recognition device during the cleaning process.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A multimodal biometric unlocking device and method for a mine shaft locker includes a locker with multiple doors mounted on its front end via hinges and locks. A multimodal lock is installed on one side of the front end of the locker. The multimodal lock includes an identification unit.

A rotating shaft is rotatably connected to the inner side of the upper end of the identification unit via a spring. The two ends of the rotating shaft are exposed on the outer side of the identification unit and fixedly connected to a cover plate. Auxiliary blocks are fixedly connected to both sides of the cover plate. An iris scanner and a human-machine interface panel are respectively installed on the upper and lower sides of the front end of the identification unit. A cleaning unit is installed in front of the iris scanner. The cleaning unit includes two sides of a fixed shell. A movable block is slidably connected inside the fixed shell. A pull rope connecting block is fixedly connected to the upper end of the movable block. A telescopic airbag is installed on one side of the upper end of the pull rope connecting block. A toothed plate is installed at one end of the inner side of the fixed shell. A pull rope is installed on one side of the upper end of the pull rope connecting block. A roller brush is rotatably connected to the inner side of the movable block.

[0005] As a further optimization of the present invention, the roller brush includes a cleaning cotton, which is fixedly connected to the outer side of the center shaft. The center shaft has a through-hole, and the center shaft has annularly distributed air holes at the position inside the cleaning cotton. Gears are fixedly connected to the outer sides of both ends of the center shaft.

[0006] As a further optimization of the present invention, the air hole is connected to the central hole, the vertical projection of the central shaft is cross-shaped, both ends of the central shaft are rotatably connected to the moving block, the gear is set inside the fixed shell, and the gear meshes with the gear plate.

[0007] As a further optimization of the present invention, the pull rope connecting block includes a plate body, the plate body has a through hole inside, and a protrusion block is fixedly connected to one side of the plate body, the protrusion block being disposed on one side of the telescopic airbag.

[0008] As a further optimization of the present invention, the movable block and the fixed shell are in one-to-one correspondence, the movable block has an L-shaped hole inside, and the fixed shell has a U-shaped cross-section.

[0009] As a further optimization of the present invention, the upper front side of the fixed shell is provided with a through hole for the pull rope to pass through, the other end of the pull rope is connected to the inner wall of the cover plate, there are two pull ropes, and the pull ropes correspond one-to-one with the fixed shell.

[0010] As a further optimization of the present invention, the upper end of the telescopic airbag is fixedly connected to the fixed shell, and the lower end of the telescopic airbag is connected to the central hole through a through hole and an L-shaped hole opened inside the moving block.

[0011] As a further optimization of the present invention, the front end of the damping block is made of rubber material, and there are multiple damping blocks. The auxiliary block has a groove inside, and there are two auxiliary blocks.

[0012] As a further optimization of the present invention, the cleaning cotton is disposed on the front side of the iris recognizer and is in close contact with the iris recognizer.

[0013] As a further optimization of the present invention, it includes the following steps: S1: Install the lockers at the mine entrance changing area. After installation, power them with 220V AC power. Allocate the corresponding storage compartments behind the lockers according to the needs of the changing personnel. After allocation, the lockers can be opened and used by entering the password through an iris recognition device or human-computer interaction device. S2: During the process of entering the password through the iris recognition device or human-computer interaction device, the cover is opened by the auxiliary block. After the cover is opened, the corresponding operation is performed to unlock the corresponding cabinet door. S3: During the opening of the cover plate, the cover plate pulls the rope to move, which in turn moves the moving block upwards. During the movement of the moving block: The moving block compresses the telescopic airbag. During the compression process, the gas inside the telescopic airbag enters the middle position of the central shaft through the through hole, the L-shaped hole opened inside the moving block, and the central hole. This part of the air is blown towards the cleaning cotton through the air hole, blowing off the dust attached to the outside of the cleaning cotton. During this process, the moving block synchronously drives the central shaft and the cleaning cotton to move upward. As the central shaft moves upward, the gears fixedly connected to both ends of the central shaft contact the gear plate, controlling the central shaft to rotate at a constant speed. This causes the cleaning cotton to rotate as it moves upward, thus cleaning the dust on the surface of the iris scanner. S4: After the cabinet door is opened, the cover plate is released. The cover plate is reset under the action of the spring. After being reset, the cover plate is positioned by the action of the damping block. After positioning, the cover plate protects the front end of the identification unit. Furthermore, the moving block is reset under the extension and retraction of the telescopic airbag.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the cleaning unit can move the cleaning cotton at the front end of the iris recognizer when the cover is opened. During the movement, the cotton can rotate, which further improves the cleaning effect. During the cleaning process, gas is continuously bulging out from the inside of the cleaning cotton, which can effectively prevent dust from getting stuck in the cleaning area and causing the iris recognizer surface to be scratched. 2. In this invention, the rotation of the cover plate is used as the power source for moving the cleaning cotton by setting the pull rope connecting block and pull rope, which does not require external power supply, making it more energy-efficient. In addition, the mechanical structure of the cleaning process has a longer service life. 3. In this invention, the telescopic spring can assist the cover to close automatically, and the damping block can position the closed cover and provide a buffering effect at the moment of closing. In addition, the auxiliary block makes it easier for staff to open the cover during actual use. Attached Figure Description

S3: During the opening of the cover plate 32, the cover plate 32 pulls the pull rope 362 to move, which in turn causes the moving block 364 to move upward. During the movement of the moving block 364: The moving block 364 compresses the telescopic airbag 365. During the compression process, the gas inside the telescopic airbag 365 enters the middle position of the central shaft 3632 through the through hole 3662, the L-shaped hole opened inside the moving block 364, and the central hole 3634. This part of the air is blown towards the cleaning cotton 3631 through the air hole 3633, blowing off the dust attached to the outside of the cleaning cotton 3631. During this process, the moving block 364 synchronously drives the central shaft 3632 and the cleaning cotton 3631 to move upward. As the central shaft 3632 moves upward, the gears 3635 fixedly connected to both ends of the central shaft 3632 contact the gear plate 367, controlling the central shaft 3632 to rotate at a uniform speed. This causes the cleaning cotton 3631 to rotate as it moves upward, thus cleaning the dust on the surface of the iris recognition device 37. S4: After the cabinet door 2 is opened, the cover plate 32 is released. The cover plate 32 is reset under the action of the spring 38.
