Description

Technical Field

[0001] This utility model relates to the field of registration and indication instruments, and in particular to an attendance information collector. Background Technology

[0002] Attendance data collectors primarily utilize automated technologies such as biometrics and location sensing to capture student attendance status in real time, verify identities, and record attendance data, achieving accurate collection and efficient management of student attendance. Current attendance methods commonly used in universities, such as mobile phone check-in or teacher roll call, have significant limitations. These methods struggle to promptly detect absenteeism and early departures, and cannot effectively prevent proxy check-ins. Furthermore, they fail to ensure a complete record of each student's true attendance. Checking student attendance one by one before class not only wastes valuable teaching time and affects the overall learning progress, but the paper-based registration and manual statistics process is also cumbersome and prone to errors. Post-class check-out rushes can lead to peak check-in times; if students cannot quickly check in and leave, they occupy classroom space, hindering subsequent classes from entering and checking in, causing congestion and disrupting the teaching order.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] See Figures 1-4 A preferred embodiment of the present invention provides an attendance information collector, comprising: a base 1, a first fingerprint recognition module, a first circuit board, and a mobile card-taking device 4.

[0030] The base 1 has a first fingerprint sensing area 2 and a mounting slot 3. The base 1 is used to install on a wall or platform suitable for time attendance systems. Its installation structure allows it to flexibly adapt to different installation environments, providing stable support on both walls and platforms to ensure the stability and reliability of the device during use. The surface of the base 1 is equipped with the first fingerprint sensing area 2, which is the recognition area where a finger is placed, used to collect and verify fingerprint information for rapid personnel identification. In addition, the base 1 also has a mounting slot 3, which is structured to accommodate a mobile time attendance device 4.

[0031] The first fingerprint recognition module is installed on the base 1 and faces the first fingerprint sensing area 2. Based on biometric authentication technology, the fingerprint recognition module achieves rapid authentication by collecting, processing, and comparing fingerprint information. It mainly consists of components such as a sensor, an image processing chip, and a security encryption chip. The sensor captures the fingerprint patterns on the finger surface, converting biometric features into digital signals. The image processing chip preprocesses the acquired fingerprint image, including noise filtering, image enhancement, and feature extraction, to improve the accuracy and reliability of recognition. The security encryption chip protects the security of fingerprint data, using encryption algorithms to encrypt and store fingerprint feature information, preventing data leakage and illegal tampering. During the recognition process, when a finger is placed in the fingerprint sensing area, the sensor senses and acquires the fingerprint image. The image processing chip analyzes and extracts feature points, compares and matches them with fingerprint templates pre-stored in the database, calculates the similarity between the two, and thus determines whether they are the same fingerprint, completing the identity recognition process.

[0032] The first circuit board is electrically connected to the first fingerprint recognition module. The first circuit board is electrically connected to the first fingerprint recognition module through wires or ribbon cables. The first circuit board integrates necessary electronic components, control chips and interface circuits to provide a stable power supply for the first fingerprint recognition module. At the same time, it is responsible for transmitting the fingerprint signal collected by the sensor to the image processing chip. After feature extraction and comparison calculation, the processing result is fed back to the main control system. During this process, the circuit board also needs to ensure the integrity of the signal and the reliability of the transmission to ensure that the entire fingerprint recognition process runs efficiently and accurately.

[0033] The mobile attendance device 4 is detachably placed in the mounting slot 3. The mobile attendance device 4 includes a handheld shell 5, a second fingerprint recognition module, and a second circuit board. The handheld shell 5 has a second fingerprint sensing area 6. The second fingerprint recognition module is installed in the handheld shell 5 and faces the second fingerprint sensing area 6. The second circuit board is electrically connected to the second fingerprint recognition module. The wall of the mounting slot 3 is provided with signal transmission contacts 10, and the second circuit board is electrically connected to the first circuit board through the signal transmission contacts 10. The mobile attendance device 4 is detachably connected to the mounting slot 3, allowing it to be quickly removed from the mounting slot 3 of the base 1 when attendance is required, facilitating handheld operation. The handheld shell 5 is easy to hold and carry. During use, students or teachers can remove the device from the base 1 at any time as needed for handheld attendance, eliminating the need for a fixed location and improving the flexibility and convenience of attendance. As an external structure, the handheld shell 5 has a second fingerprint sensing area 6 on its surface for fingerprint collection. The second fingerprint recognition module is located inside the handheld shell 5 and precisely faces the sensing area to ensure effective acquisition of fingerprint signals. The second fingerprint recognition module can be an optical sensor or a capacitive sensor, paired with a signal processing and encryption chip to achieve fingerprint image acquisition, processing, and secure encryption. The second circuit board is electrically connected to the recognition module, integrating necessary electronic components and a control chip. It transmits fingerprint data to the processing unit, performs feature extraction and comparison analysis, and then provides feedback on the recognition results, ensuring the independent operation and high-precision recognition function of the mobile attendance device 4. The base 1 and the mobile attendance device 4 are interconnected via signal transmission contact 10. The base 1 has an information pre-storage function, allowing the import of fingerprint information of students attending classes in the classroom. When the mobile attendance device 4 is placed on the base 1, the base 1 can synchronize the stored fingerprint information data to the mobile attendance device 4 via the signal transmission contact 10, eliminating the need to re-enter fingerprint information on the mobile attendance device 4, saving time and improving efficiency. Similarly, the student attendance information recorded by the mobile attendance device 4 can also be stably transmitted back to the base 1 via the signal transmission contact 10. Base 1 serves as a data aggregation node, integrating and storing the collected attendance information. This facilitates unified recording and management of data by the school's academic affairs management department, providing efficient and convenient technical support for the school's attendance management work.

[0034] Working Principle: The base 1 has a first fingerprint sensing area 2. The first fingerprint recognition module is placed inside the base 1, with the sensor window coplanar with the sensing area and facing the finger to collect fingerprint images. The first circuit board is electrically connected to the first fingerprint recognition module to form a power supply and communication link. The circuit board integrates analog-to-digital conversion, feature extraction, template matching, and result output links. The receiving module outputs and compares with the pre-stored fingerprint database to output the student's identity result. The side wall of the base 1 has a mounting slot 3, and the mobile card-taking device 4 can be detachably installed on the base 1. The handheld shell 5 has a second fingerprint sensing area 6. The second fingerprint recognition module is aligned with the sensing area and collects fingerprint images. The second circuit board is electrically connected to the second fingerprint recognition module to form a power supply and communication link. It has the same signal processing link as the first circuit board and can also independently complete the tasks of fingerprint collection, feature comparison, identity verification, and outputting the student's card-taking result. When the base 1 and the mobile card-taking device 4 are separated, they can be flexibly deployed in different spatial locations to divert the card-taking crowd and shorten the queue length.

[0035] Clearly, the base 1 internally houses a first fingerprint sensing area 2, a first fingerprint recognition module, and a first circuit board, all electrically connected in sequence to form a complete fingerprint recognition circuit. The first fingerprint recognition module collects fingerprint image data, transmits it to the first circuit board for feature extraction and comparison calculations, and finally uploads the recognition result, completing the fingerprint recognition and attendance information confirmation for the base 1. Similarly, the mobile attendance device 4 is equipped with a second fingerprint sensing area 6, a second fingerprint recognition module, and a second circuit board, all electrically connected in sequence to independently constitute a complete fingerprint recognition attendance system, enabling fingerprint recognition and attendance verification in mobile scenarios. The base 1 and the mobile attendance device 4 are detachably mechanically and electrically connected, facilitating quick assembly and disassembly. When the base 1 and the mobile attendance device 4 are separated, they can be flexibly deployed in different spatial locations to divert attendance crowds and shorten queue lengths. This effectively avoids the crowd gathering caused by traditional single-point attendance, optimizes overall attendance efficiency, significantly improves the smoothness and convenience of the attendance process, and enhances the intelligence level of campus attendance management.

[0036] In this embodiment, preferably, the first fingerprint sensing area 2 and the second fingerprint sensing area 6 are both recessed structures. The first fingerprint sensing area 2 adopts a sunken recessed structure, with its depth matching the curvature of the fingertip to ensure comfortable and snug finger placement. The sidewall of the recess has a limiting slope to facilitate finger positioning and prevent displacement. A fingerprint collection window is located at the center of the bottom of the recess, and the surface of the collection window is made of a wear-resistant, oleophobic, transparent material, protecting the collection window and reducing fingerprint residue. The second fingerprint sensing area 6 also uses a sunken recessed design, with its depth matching the curvature of the fingertip to ensure comfortable and snug finger placement. The sidewall of the recess has a limiting slope to facilitate finger positioning and prevent displacement. A fingerprint collection window is located at the center of the bottom of the recess, and the surface of the collection window is made of a wear-resistant, oleophobic, transparent material, protecting the collection window and reducing fingerprint residue.

[0037] In this embodiment, preferably, the base 1 is equipped with a first display screen 7, which is electrically connected to the first circuit board; the handheld shell 5 is equipped with a second display screen 8, which is electrically connected to the second circuit board. The base 1 is equipped with the first display screen 7, which is connected to the first circuit board through a stable and reliable electrical connection to ensure efficient signal transmission and accurate display; the handheld shell 5 is equipped with the second display screen 8, which is also electrically connected to the second circuit board to ensure the normal operation of the display function. Both the first display screen 7 and the second display screen 8 are used to display the key information of the clock-in user obtained by the fingerprint recognition system, including the clock-in user's identity, clock-in time, and clock-in location, providing accurate and comprehensive visual data support for attendance management, and effectively improving the practicality and reliability of the device in attendance application scenarios.

[0038] In this embodiment, preferably, the handheld shell 5 is provided with anti-slip protrusions 9 on both sides adjacent to the second display screen 8. The anti-slip protrusions 9 effectively increase the friction when gripping, preventing the device from accidentally slipping. The anti-slip protrusions 9 are made of wear-resistant material, ensuring good anti-slip performance even after long-term use. During handheld attendance, teachers or students can use these protrusions to hold the device stably.

[0039] In this embodiment, preferably, multiple mounting slots 3 are provided, and multiple mobile attendance devices 4 are provided, with each mobile attendance device 4 corresponding to one of the mounting slots 3. By providing multiple mobile attendance devices 4, attendance can be taken simultaneously at the beginning or end of a course, avoiding student congestion and greatly improving attendance efficiency and reducing time. It can be understood that, as an alternative implementation, multiple mobile attendance devices 4 can be allocated to instructors as needed, with each instructor carrying an independent device. This facilitates accurate collection and independent statistics of attendance data for their respective courses, and the mobile attendance devices 4 are easy for instructors to carry, enhancing the flexibility and autonomy of attendance management in the teaching environment.

[0040] Understandably, as an alternative implementation, base 1 can serve as a data transfer station for attendance records. Equipped with wireless or wired transmission devices, it enables data upload and download. It can stably transmit collected data to a server for storage and subsequent processing via wireless or wired means, and simultaneously download data from the server to the base 1's storage for local storage or backup. This effectively reduces the workload of manually importing data into the base 1's storage, avoids potential errors from manual operation, improves the efficiency and accuracy of data transmission, and makes data management more convenient and efficient, providing strong support for the intelligent operation of the equipment and the efficient utilization of data.

[0041] In this embodiment, preferably, one of the base 1 and the handheld shell 5 is provided with a first magnetic element 11; the other is provided with a second magnetic element 12, and the first magnetic element 11 and the second magnetic element 12 are attracted together. The first magnetic element 11 on the base 1 and the second magnetic element 12 on the handheld shell 5 generate magnetic force through interaction, realizing a tight connection between the base 1 and the handheld shell 5. When the base 1 and the handheld shell 5 are magnetically attracted together, the signal transmission contact 10 located at the connection point can be accurately aligned and maintain contact, thereby entering the working state. This design ensures that the signal transmission contact 10 can reliably function during data transmission, facilitating the rapid establishment of an effective electrical connection when data transmission is required, and achieving efficient data transmission. At the same time, the magnetic attraction connection method has the advantage of quickly achieving detachable connection, making the installation and disassembly of the handheld shell 5 and the base 1 simple and quick, without the need for additional tools or complex mechanical structures, and can complete the switching of connection states, greatly improving the flexibility and convenience of device use.

[0042] In this embodiment, preferably, the base 1 is provided with multiple buttons 13, all of which are electrically connected to the first circuit board. The multiple buttons 13 work together to control various operations on the attendance information collector. The functions of the buttons 13 include system control, such as starting, stopping, and restarting the device to ensure stable operation; fingerprint enrollment, facilitating user fingerprint input and improving the accuracy and uniqueness of attendance data; and access control, used to set and adjust the access levels of different users to ensure the security of critical data and operational compliance. Through these buttons 13, users can conveniently manage and operate the device comprehensively, improving the efficiency and accuracy of attendance management while ensuring the safe and stable operation of the system.

[0043] In this embodiment, preferably, the base 1 is equipped with a first storage battery, which is electrically connected to the first circuit board; the base 1 is also connected to a power cord. The first storage battery is reliably connected to the first circuit board, ensuring a stable power supply to support the basic operating functions and data processing needs of the device. It can be understood that, as an alternative implementation, the base 1 is equipped with a power cord connection device, allowing the device to connect to an external power source. This not only ensures continuous operation of the device when an external power source is available, but also enables the first storage battery to serve as a backup power source in the absence of an external power source, maintaining the basic functions of the device and temporary data storage, ensuring the flexibility and reliability of the device, and ensuring stable operation and data security in various environments.

[0044] Furthermore, the mobile attendance device 4 also includes a second battery, which is electrically connected to the first battery. This allows the mobile attendance device 4 to maintain a basic power supply even when detached from the base 1, ensuring portability and operational flexibility. When the mobile attendance device 4 is magnetically connected to the base 1, the signal transmission contact 10 enables stable data transmission, ensuring efficient and accurate exchange of attendance records and other information between the mobile attendance device 4 and the base 1, achieving synchronized data updates. The signal transmission contact 10 also has a charging function, providing stable power to the mobile attendance device 4 during data synchronization, maintaining its normal operation and extending its usage time. In actual teaching scenarios, teachers can conveniently carry the mobile attendance device 4 with them during class. After completing the attendance check-in task before class, they can magnetically connect the device to the base 1 pre-installed in the classroom. This connection method allows for the rapid establishment of a data transmission link, enabling the complete synchronization of student attendance records and classroom interaction information recorded on the mobile attendance device 4 to the terminal device connected to the base 1. Simultaneously, the base 1 provides power to the mobile attendance device 4, ensuring its continued operation in subsequent teaching activities. This design not only improves the efficiency and convenience of attendance management but also provides a continuous energy guarantee for the mobile attendance device 4, facilitating the smooth conduct of teaching activities and the effective implementation of teaching management.
