Description
Technical Field
[0001] This invention belongs to the field of Internet of Things (IoT) application technology, specifically a remote attendance device based on IoT technology. Background Technology
[0002] Remote attendance devices based on Internet of Things (IoT) technology utilize the sensing, transmission, and processing capabilities of IoT to connect attendance terminals to the network. This allows employees to collect attendance information remotely and transmit the data to the management system for recording and processing. It is a product of the integration of IoT with human resource management attendance processes, primarily used to improve attendance efficiency and accuracy, and facilitate attendance data management.
[0003] The company's remote attendance equipment not only allows employees to clock in from a distance, but also allows employees to clock in using fingerprint or facial recognition. These devices are generally fixed to the wall for easy facial recognition. However, since employees have different heights, some attendance devices are bolted to the wall, making them unable to move up or down. Taller employees need to bend over to use the facial recognition system, while shorter employees may not be able to use it because their faces cannot align with the height of the facial recognition screen. This results in low adaptability and poor flexibility. Therefore, to address these issues, a remote attendance device based on Internet of Things (IoT) technology is proposed. Summary of the Invention
[0004] To address the problems mentioned in the background section, this invention provides a remote attendance device based on Internet of Things (IoT) technology, which solves the problem that existing technologies cannot adjust the height to accommodate employees of different heights for facial recognition attendance.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a remote attendance device based on Internet of Things technology, comprising a housing, a face recognition window provided on the front outer wall of the housing, a fingerprint recognition window provided on the front outer wall of the housing, a dustproof mechanism provided on the front outer wall of the housing, and a fixing plate provided on the rear outer wall of the housing through an adjustment mechanism; The adjustment mechanism includes a fixed block, the inner wall of which is elastically connected to a limit block via a connecting spring, the outer wall of which is engaged with a connecting block, the outer wall of which has a through groove, the inner wall of which is elastically connected to a wedge via a telescopic spring, the inner wall of which is slidably connected to a trapezoidal block, the inner wall of which is slidably connected to a connecting rod, and the inner wall of which is engaged with a slot.
[0006] Preferably, the fixing block is fixedly connected to the outer wall of the rear end of the housing, and the fixing block is in contact with the inner wall of the connecting block.
[0007] Preferably, one end of the connecting spring is fixedly connected to the outer wall of the limiting block, the other end of the connecting spring is fixedly connected to the inner wall of the fixing block, the limiting block is slidably connected to the inner wall of the fixing block, and the limiting block is engaged with the through groove.
[0008] Preferably, one end of the telescopic spring is fixedly connected to the outer wall of the wedge block, and the other end of the telescopic spring is fixedly connected to the inner wall of the connecting block.
[0009] Preferably, the outer wall of the wedge is slidably connected to the inner wall of the connecting block, the wedge is engaged with the slot, and the outer wall of the connecting block is in contact with the inner wall of the fixing plate.
[0010] Preferably, one end of the connecting rod is slidably connected to the outer wall of the trapezoidal block, and the other end of the connecting rod is fixedly connected to the outer wall of the wedge block.
[0011] Preferably, the dustproof mechanism includes a baffle, a sliding plate is fixedly connected to the outer wall of the rear end of the baffle, the sliding plate is elastically connected to the inner wall of the front end of the housing by a return spring, a long plate is fixedly connected to the outer wall of the rear end of the baffle, a groove is formed on the outer wall of the long plate, a movable shaft is contacted on the inner wall of the groove, a soft brush is fixedly connected to the outer wall of the movable shaft, and a guide groove is formed on the inner wall of the front end of the housing.
[0012] Preferably, the baffle is slidably connected to the outer wall of the front end of the housing, and the sliding plate is slidably connected to the inner wall of the front end of the housing.
[0013] Preferably, one end of the return spring is fixedly connected to the inner wall of the front end of the housing, and the other end of the return spring is fixedly connected to the outer wall of the sliding plate.
[0014] Preferably, the moving shaft contacts the inner wall of the guide groove, and the soft brush contacts the fingerprint recognition window.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a combination of trapezoidal blocks and wedges. By engaging the wedges with the slots, the connecting block and the housing can be fixed in a fixed plate. Users can then use facial and fingerprint recognition to clock in. Users of different heights can press the trapezoidal blocks to move the connecting block and the housing up and down within the inner wall of the fixed plate to adjust to a suitable position for facial recognition clocking in. This makes it convenient for people of different heights to use the device. Taller users do not need to bend over to clock in, and shorter users are not prevented from using the device. This invention, through the combination of a baffle and a soft brush, allows for fingerprint recognition check-in by moving the baffle upwards. After check-in, the baffle moves downwards to reset. The baffle prevents dust from the outside air from adhering to the fingerprint recognition screen. Furthermore, the soft brush can be driven to wipe the screen as the baffle moves up and down, ensuring the cleanliness of the screen and thus avoiding the problem of dust or dirt from the user's fingers affecting the screen's recognition performance over a long period of time. This invention utilizes a combination of limiting blocks and through slots to secure the housing during installation. The limiting blocks engage with the through slots to fix the housing in the connecting block, which is then installed in the fixing plate. When the housing needs to be disassembled for internal maintenance, both sets of limiting blocks can be pressed simultaneously to disengage them from the through slots, allowing for quick and easy removal of the housing for maintenance. This simplifies the disassembly and installation process, eliminating the need for multiple bolt rotations and saving time and effort. Attached Figure Description

[0018] 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.
[0019] like Figures 1 to 6 As shown, the present invention provides a remote attendance device based on Internet of Things (IoT) technology, including a housing 1. A face recognition window 5 and a fingerprint recognition window 7 are provided on the front outer wall of the housing 1. A dustproof mechanism 4 is provided on the front outer wall of the housing 1. A fixing plate 3 is provided on the rear outer wall of the housing 1 through an adjustment mechanism 2. The adjustment mechanism 2 includes a fixing block 201. A limit block 202 is elastically connected to the inner wall of the fixing block 201 through a connecting spring 203. A connecting block 204 is snapped onto the outer wall of the fixing block 201. A through groove 205 is opened on the outer wall of the connecting block 204. A wedge block 206 is elastically connected to the inner wall of the connecting block 204 through a telescopic spring 207. A trapezoidal block 208 is slidably connected to the inner wall of the connecting block 204. A connecting rod 209 is slidably connected to the inner wall of the connecting block 204. A slot 6 is opened on the inner wall of the fixing plate 3.
[0020] The above solution employs the following: The housing 1 is the main body of a remote attendance device based on IoT technology. It can not only perform fingerprint and facial recognition attendance through the fingerprint recognition window 7 and the facial recognition window 5, but also acquire employee attendance information through some form of identification. This information is then transmitted to a remote server or management system for storage and processing via a network, allowing employees to complete attendance records even when they are far from the designated attendance location. It also has built-in wireless and Ethernet interfaces, supporting mobile networks and other communication methods. It can connect to the company's internal network or the internet, uploading collected facial and fingerprint data, as well as attendance records, to a remote server in real time, enabling remote attendance management. Furthermore, it can connect with the company's internal network. Integration with other smart devices or systems, such as access control systems and security monitoring systems, and the realization of information interaction and collaborative work through IoT technology are all existing technologies and will not be elaborated here. The fixing plate 3 can be fixed to the wall by bolts or other means. The housing 1 can be fixed to the fixing plate 3 by the adjustment mechanism 2, and the height of the housing 1 can be adjusted by the adjustment mechanism 2 to facilitate use by people of different heights, and it can also be quickly disassembled and installed. The dustproof mechanism 4 can cover the fingerprint recognition window 7 when not in use to prevent dust from falling on the screen and affecting the recognition effect. Before and after use, the screen can be wiped with a soft brush 402 to keep the screen clean.
[0021] like Figures 1 to 3As shown, the fixing block 201 is fixedly connected to the outer wall of the rear end of the housing 1, and the fixing block 201 is in contact with the inner wall of the connecting block 204; one end of the connecting spring 203 is fixedly connected to the outer wall of the limiting block 202, and the other end of the connecting spring 203 is fixedly connected to the inner wall of the fixing block 201; the limiting block 202 is slidably connected to the inner wall of the fixing block 201, and the limiting block 202 is engaged with the through groove 205; one end of the telescopic spring 207 is fixedly connected to the outer wall of the wedge block 206, and the other end of the telescopic spring 207 is fixedly connected to the inner wall of the connecting block 204; the outer wall of the wedge block 206 is slidably connected to the inner wall of the connecting block 204, and the wedge block 206 is engaged with the slot 6; the outer wall of the connecting block 204 is in contact with the inner wall of the fixing plate 3; one end of the connecting rod 209 is slidably connected to the outer wall of the trapezoidal block 208, and the other end of the connecting rod 209 is fixedly connected to the outer wall of the wedge block 206.
[0022] Using the above scheme: the housing 1 can be installed in the inner wall of the connecting block 204 through the fixing block 201. Two sets of limiting blocks 202 and connecting springs 203 are provided, symmetrically distributed on both sides of the inner wall of the fixing block 201. When the fixing block 201 is inserted into the connecting block 204, the elastic force of the connecting springs 203 causes the limiting block 202 to engage with the through groove 205, thus fixing the fixing block 201 and the connecting block 204. Pressing the limiting block 202 to disengage it from the through groove 205 releases the fixing block 201 from the housing 1, allowing for convenient and quick removal of the housing 1 for internal maintenance. The wedge block 206 remains in an upward-facing arc state. When not affected by external forces, the extension spring 207... The elastic force causes it to pop outward, and its direct surface contacts the inner wall of the card slot 6. The card slot 6 provides support, thus fixing the connecting block 204 in the fixing plate 3. When a tall person uses it, the connecting block 204 can be pulled upward, and the arc surface of the wedge block 206 is squeezed inward by the inner wall of the card slot 6, which can move the housing 1 upward to a higher position, so that the user can open it for face recognition without bending over. When a shorter person uses it, the trapezoidal block 208 can be pressed to move the two sets of wedge blocks 206 to the middle at the same time, disengaging them from the card slot 6, and moving the connecting block 204 and the housing 1 downward to a suitable position for face recognition check-in. This is more convenient and can be adjusted according to the user's height, making it more flexible.
[0023] like Figure 3 As shown, when there is no external force, the elastic force of the telescopic spring 207 keeps the two sets of wedges 206 on both sides. The wedges 206 pull the two sets of connecting rods 209 to move outward. The other end of the connecting rod 209 remains in contact with the top of the inclined surface of the trapezoidal block 208. When the trapezoidal block 208 is pressed upward, the connecting rod 209 moves along the top of its inclined surface to the bottom and gradually moves towards the middle. This drives the two sets of wedges 206 to move towards the middle at the same time and disengage from the slot 6. Thus, the connecting block 204 and the housing 1 can be moved downward as a whole.
[0024] like Figures 4 to 6 As shown, the dustproof mechanism 4 includes a baffle 401. A sliding plate 403 is fixedly connected to the outer wall of the rear end of the baffle 401. The sliding plate 403 is elastically connected to the inner wall of the front end of the housing 1 by a return spring 404. A long plate 405 is fixedly connected to the outer wall of the rear end of the baffle 401. A groove 406 is provided on the outer wall of the long plate 405. A moving shaft 407 is in contact with the inner wall of the groove 406. A soft brush 402 is fixedly connected to the outer wall of the moving shaft 407. A guide groove 408 is provided on the inner wall of the front end of the housing 1.
[0025] Using the above solution: Users can also use the fingerprint recognition window 7 for fingerprint check-in. When not in use, the reset spring 404 keeps the sliding plate 403 in the downward position due to its own elasticity, which drives the baffle 401 to close the front opening of the fingerprint recognition window 7, thus preventing dust from falling on the screen of the fingerprint recognition window 7 and affecting the recognition effect. When fingerprint check-in is required, the baffle 401 can be moved upward, and the sliding plate 403 squeezes the reset spring 404 to contract under force, exposing the screen of the fingerprint recognition window 7 for fingerprint check-in. After check-in is completed, the elasticity of the reset spring 404 causes the sliding plate 403 and the baffle 401 to move downward to reset. During the up and down movement of the baffle 401, the soft brush 402 can be moved along the screen surface to wipe it. Thus, the screen is wiped before the finger is placed on the screen or after check-in is completed, keeping the screen of the fingerprint recognition window 7 clean. It will not be affected by dust in the air, nor by the oil, dust and other dirt on the user's fingers, which will affect the subsequent recognition effect.
[0026] like Figures 4 to 6 As shown, the baffle 401 is slidably connected to the outer wall of the front end of the housing 1, and the sliding plate 403 is slidably connected to the inner wall of the front end of the housing 1; one end of the reset spring 404 is fixedly connected to the inner wall of the front end of the housing 1, and the other end of the reset spring 404 is fixedly connected to the outer wall of the sliding plate 403; the moving shaft 407 is in contact with the inner wall of the guide groove 408, and the soft brush 402 is in contact with the fingerprint recognition window 7.
[0027] Using the above scheme: the baffle 401 can only move up and down on the front outer wall of the housing 1. Two sets of long plates 405 are provided, and the soft brush 402 is disposed between the two sets of long plates 405. The moving shaft 407 is fixedly connected to both sides of the soft brush 402 and slidably connected to the sliding grooves 406 on both sides, while also contacting the inner wall of the guide groove 408. When the baffle 401 moves upward, it drives the long plates 405 to move upward synchronously, so that the moving shaft 407 and the soft brush 402 move synchronously. The soft brush 402 is set at an angle and adheres to... The fingerprint recognition window 7 is tilted during movement and moves along the inner wall of the slide groove 406. Since the moving shaft 407 is in contact with the inner wall of the guide groove 408, which is tilted, it can move along the inner wall of the guide groove 408 during movement, and then move obliquely upward with the movement of the baffle 401 to wipe the screen. When the baffle 401 moves downward, the moving shaft 407 and the soft brush 402 move obliquely downward to wipe the screen again and reset.
[0028] Working principle and usage process of this invention: The housing 1, as the main body of the remote attendance device, integrates various key components and functional modules. It realizes employee identity recognition and attendance functions through the face recognition window 5 and the fingerprint recognition window 7. At the same time, it uses Internet of Things technology to transmit attendance data to a remote server for storage and processing, realizing remote attendance management. When installing the housing 1, the two sets of limiting blocks 202 can be pressed inward first, the connecting spring 203 is compressed, and the fixing block 201 is inserted into the inner wall of the connecting block 204. When the limiting block 202 corresponds to the through groove 205, the elasticity of the connecting spring 203 causes the limiting block 202 to pop out and engage with the through groove 205, thereby fixing the fixing block 201 and the connecting block 204, realizing the initial connection between the housing 1 and the connecting block 204.
[0029] The fixing plate 3 can be fixed to the wall by bolts or other means. The outer wall of the connecting block 204 contacts the inner wall of the fixing plate 3. When there is no external force, the wedge 206 pops out due to the elastic force of the telescopic spring 207. The slot 6 supports the straight surface of the wedge 206, so that the connecting block 204 can be fixed in the fixing plate 3, thereby fixing the housing 1 at a specific position on the fixing plate 3.
[0030] When a taller person needs to use facial recognition for check-in, they can pull the connecting block 204 upwards. The curved surface of the wedge block 206 is squeezed by the inner wall of the slot 6, causing the wedge block 206 to move inwards. The telescopic spring 207 is compressed. As the connecting block 204 moves upwards, the wedge block 206, under the elastic force of the telescopic spring 207, will re-engage with the slot 6 above, thereby moving the housing 1 upwards to a higher position, making it convenient for taller users to use facial recognition for check-in without bending over. For shorter users, the trapezoidal block 208 can be pressed upwards, connecting... One end of the rod 209 moves from the top of the inclined surface of the trapezoidal block 208 to the bottom and gradually moves towards the middle, causing the two sets of wedges 206 to move towards the middle at the same time. The wedges 206 disengage from the slots 6. At this time, the connecting block 204 and the housing 1 are pulled down to move the connecting block 204 and the housing 1 to the appropriate position. After releasing the trapezoidal block 208, the wedges 206 will return to their initial position under the action of the telescopic spring 207 and engage with the slots 6 to fix the housing 1. This makes it easier for users of different heights to use, and it is more flexible and adaptable.
[0031] When the fingerprint recognition window 7 is not in use, the baffle 401 closes the front opening of the fingerprint recognition window 7 to prevent dust from falling on the screen of the fingerprint recognition window 7 and affecting the recognition effect. When fingerprint check-in is required, the user moves the baffle 401 upward. At this time, the sliding plate 403 will squeeze the reset spring 404, causing the reset spring 404 to contract under force. After the baffle 401 moves upward, the screen of the fingerprint recognition window 7 is exposed, and employees can perform fingerprint check-in operations.
[0032] When the baffle 401 moves upward, the long plate 405 fixedly connected to the outer wall of the rear end of the baffle 401 also moves upward synchronously, and the moving shaft 407 moves synchronously. At the same time, since the guide groove 408 is inclined, the moving shaft 407 will move obliquely upward along the inner wall of the guide groove 408 and the slide groove 406, so that the soft brush 402 maintains an inclined state and moves obliquely upward during the movement, and wipes the screen in contact with it. After the card is checked in, the user releases the baffle 401, and the spring force of the return spring 404 causes the sliding plate 403 and the baffle 401 to move downward and reset. During the downward movement of the baffle 401, the moving shaft 407 and the soft brush 402 will move obliquely downward to wipe the screen again. In this way, the soft brush 402 can wipe the screen once before the finger is placed on the screen and after the card is checked in, keeping the fingerprint recognition window 7 screen clean and free from dust in the air and dirt such as oil and dust on the user's fingers, ensuring the recognition effect in the later stage.
