[0038] like Figures 1 to 13 As shown, an attendance and access control integrated machine with intelligent identification through AI software described in one embodiment of the utility model includes a main control module 1, an access lock 7, and a power module 8. The main control module 1 is connected to the data storage module 2, the sensor module 3, the expansion module 4 and the conversion module 6. The main control chip used in the main control module 1 is RK1109, and the expansion module 4 is connected to the data transmission module 401; the access lock 7 is communicated with the main control module 1 through the data transmission module 401, and the main control module 1 controls the switch of the access lock 7; the power module 8 is used to supply power to the main control module 1 and the access lock 7.

[0039] The sensor module 3 includes a camera module 301 and a camera lens driving module 302 .

[0040] The camera lens driving module 302 can accurately drive the camera lens to adjust the shooting angle and focal length, thereby improving the shooting effect and further enhancing the clarity and recognition rate of the image.

[0041] The main control module 1 is implanted with an AI intelligent algorithm, which enables the computer chip to learn from previous results and obtain information updates without human intervention, and simply feeds back a large amount of structured data to complete the task. In this embodiment, the images collected by the camera are analyzed and recognized to complete the monitoring system with specific functional requirements. For example, the camera will record in real time or take pictures at short intervals, analyze and compare the facial images taken and the facial images set by the system, and realize the functions of active analysis and recognition through the AI ​​intelligent algorithm. At present, AI intelligent algorithms include K-means algorithm and neural network algorithm, etc. Different instructions are made according to the results of recognition and analysis, which can support AI behavior analysis monitoring, AI face recognition monitoring system, etc. The command output includes a speaker alarm, or a wifi network connection to client mobile phones, tablets and other communication devices.

[0042] AI intelligent algorithms are used to improve the security and reliability of user use. It can not only automatically identify users and record user information, but also prevent user information leakage.

[0043] The sensor module 3 includes a fill light driving module 303, the fill light driving module 303 is electrically connected to the fill light, and the fill light driving module 303 is used to drive the fill light. The fill light includes a white light fill light and an infrared fill light.

[0044] The application of white light fill light is mainly to provide visible light illumination, ensuring that the camera can capture clear facial images when the ambient light is insufficient. Its working principle is to supplement the insufficient light in the environment by emitting white light, improving the brightness and clarity of the object being photographed or viewed. In the attendance and access control integrated machine, the white light fill light automatically lights up when a person approaches, providing sufficient illumination for the camera, so that the face recognition module 5 can accurately capture the facial features, achieve fast and accurate identity verification, and facilitate personnel to open the gate.

[0045] Infrared fill lights are mainly used at night or in low-light environments to illuminate and identify objects by emitting infrared light. Since infrared rays can penetrate haze, smoke and light fog, infrared fill lights can ensure that the camera can capture clear images even in bad weather conditions. In the attendance and access control integrated machine, the application of infrared fill lights enables the system to work normally at night or in low-light conditions, greatly broadening the scope of use of the attendance and access control system.

[0046] In addition, the combination of white light and infrared light enables the attendance and access control integrated machine to maintain stable recognition effect under various lighting conditions. Whether it is day or night, sunny or rainy, the system can accurately identify the identity of people and realize efficient and safe access control management.

[0047] The main control module 1 is provided with a face recognition module 5 .

[0048] When the attendance access control integrated machine is working, when a person approaches the access control, the sensor module 3 senses the signal and triggers the fill light driving module 303, so that the white light fill light and the infrared fill light light up, ensuring that a clear face image can be obtained under any lighting conditions. After receiving the instruction, the camera lens driving module 302 quickly drives the camera lens to adjust to the optimal shooting angle and focal length. Subsequently, the camera module 301 starts working to capture the face image of the person. Subsequently, the RK1109 chip in the main control module 1 quickly processes the captured face image, compares it with the face database through the face recognition module 5, and realizes identity authentication. Once the recognition is successful, the main control module 1 sends an instruction to the access control lock 7 through the data transmission module 401 to open it automatically. At the same time, the attendance information will also be stored in the data storage module 2 through the data transmission module 401 in the expansion module 4, which is convenient for later statistics and management. The whole process is fast and accurate, which greatly improves the efficiency and security of access control management.

[0049] The attendance and access control integrated machine realizes efficient and safe access control and attendance management through AI software intelligent recognition technology. The face recognition module 5 it adopts has a high degree of accuracy and stability, which can effectively put an end to the phenomenon of punching in for others and improve the authenticity of attendance data. At the same time, the application of white light fill light and infrared fill light ensures the recognition effect under various lighting conditions and improves the applicability of the system. In addition, the RK1109 chip used in the main control module 1 has powerful processing capabilities and efficient power consumption control, which ensures the stable operation and long-term use of the system. Overall, the attendance and access control integrated machine not only improves the intelligent level of access control management, but also provides strong technical support for the security management of enterprises and institutions.

[0050] The main control module 1 and the conversion module 6 are connected by I2C bus communication. In terms of hardware, the I2C bus only needs two wires, one data line and one clock line. The bus interface has been integrated inside the chip, and no special interface circuit is required. Moreover, the filter of the interface circuit on the chip can filter out the burr wave on the bus data. Therefore, the I2C bus simplifies the hardware circuit PCB wiring, reduces the system cost, and improves the system reliability. Because the I2C chip has no connection with the system except these two wires and a small number of interrupt lines, it can be easily standardized and modularized for reuse. The I2C bus is a multi-host bus. If two or more hosts initialize data transmission at the same time, data corruption can be prevented through conflict detection and arbitration. Each device connected to the bus has a unique address. Any device can be used as both a host and a slave, but only one host is allowed at the same time. Data transmission and address setting are set by software, which is very flexible. The addition and deletion of devices on the bus does not affect the normal operation of other devices.

[0051] The application of I2C bus in the attendance and access control integrated machine greatly simplifies the hardware circuit PCB wiring, reduces the system cost, and improves the reliability and flexibility of the system. The use of I2C bus communication connection not only reduces the design complexity of the interface circuit, but also reduces the risk of system failure. In addition, the standardized and modular design of the I2C bus allows users to easily expand and upgrade the system, improving the maintainability and scalability of the system. In actual applications, communication connection can be achieved through the IO port or USB port, providing users with more choices and flexibility, and meeting the application requirements in different scenarios.

[0052] In a preferred embodiment, the expansion module 4 includes a UART serial port 409 and a JTAG interface 410 for debugging and verifying each functional module.

[0053] The UART serial port 409 is mainly used for serial communication with a computer or other devices, and realizes the debugging and configuration of the attendance and access control integrated machine by sending and receiving data. The JTAG interface 410 is a more in-depth debugging interface, which allows developers to directly access the underlying information of the hardware, so as to perform more accurate and efficient debugging. During the debugging process, developers can use these two interfaces to test each functional module such as the main control module 1, the sensor module 3, the data transmission module 401, etc. one by one to ensure that they are working properly.

[0054] The UART serial port 409 and JTAG interface 410 of the expansion module 4 provide great convenience for the debugging and verification of the attendance and access control integrated machine. Through these two interfaces, developers can quickly locate and solve potential problems to ensure the stability and reliability of each functional module. This not only improves the development efficiency of the product, but also reduces the difficulty and cost of later maintenance. At the same time, the standardized design of these two interfaces also makes the debugging and verification of the attendance and access control integrated machine more standardized and unified, improving the efficiency and quality of the entire development process.

[0055] like Figure 7 As shown, in a preferred embodiment, the expansion module 4 includes an IC card module 411 .

[0056] When the user brings the IC card close to the reader, the reader will send out a radio frequency signal to activate the IC card and exchange data with the IC card through a specific communication protocol. The IC card module 411 is responsible for parsing the data read from the IC card and transmitting it to the main control module 1 for verification. If the verification is successful, the main control module 1 will send a command to the access control system to allow the user to pass through the access control.

[0057] In this embodiment, the security and reliability of the access control system are improved by setting the IC card module 411, and illegal intrusion is effectively prevented through the identity authentication mechanism. Secondly, the use of the IC card module 411 simplifies the user's operation process. The user only needs to carry an IC card to complete the identity authentication without having to remember complex passwords or perform tedious registration. In addition, the IC card module 411 also supports a variety of functional expansions, such as attendance records, authority management, etc., which further enhances the practicality and flexibility of the access control system. In addition, it provides efficient and secure identity authentication and access control functions for the attendance and access control integrated machine, meeting the diverse needs of modern access control systems.

[0058] In a preferred embodiment, the expansion module 4 includes a TF card interface 412 .

[0059] When the TF card is inserted into the TF card interface 412, the main control module 1 can identify and access the data on the TF card. Through this interface, the user can store data such as attendance records and access control logs in the TF card to achieve data backup and transfer. At the same time, the TF card interface 412 also supports data reading and writing operations, so that the attendance and access control integrated machine can flexibly load configuration information or update the software version from the TF card.

[0060] like Fig. 9 , Fig.10 ,and Fig.12 As shown, the storage module includes a memory module 201 and a flash memory module 202 .

[0061] The memory module 201, as a temporary storage space, is responsible for storing the intermediate data and program instructions when the system is running, ensuring that the system can run smoothly and quickly. The flash memory module 202 is used as a long-term storage medium to store key data such as system configuration information and attendance records, and can maintain data persistence even in the case of power failure. When the system needs to read or write data, the main control module 1 will send instructions to the corresponding storage module to complete the data access operation.

[0062] In this embodiment, the high-speed reading and writing capability of the memory module 201 effectively improves the operating efficiency of the system, ensuring real-time response and smooth user experience. The large capacity and persistence of the flash memory module 202 ensure the security and reliability of the data, avoiding the risk of data loss or damage. In addition, the scalability of the flash memory module 202 also enables the system to easily cope with the growth of future data volume, providing a strong guarantee for the long-term stable operation of the attendance and access control integrated machine.

[0063] In a preferred embodiment, an encryption module is provided between the main control module 1 and the conversion module 6 , and a UART (Universal Asynchronous Receiver / Transmitter) for communication between the conversion module 6 and the encryption module is provided between the conversion module 6 and the encryption module.

[0064] In the data transmission process between the main control module 1 and the conversion module 6, the encryption module plays a vital role. When the main control module 1 needs to send data to the conversion module 6, the data will first be encrypted by the encryption module to ensure the security of the data. The encryption module uses advanced encryption algorithms, including symmetric encryption algorithms, asymmetric encryption algorithms, and hash algorithms to confuse and replace the original data and generate ciphertext that is difficult to crack. Subsequently, the encrypted data is transmitted to the conversion module 6 via UART. After receiving the data, the conversion module 6 also needs to communicate with the encryption module through UART, decrypt the ciphertext, and restore it to the original data for further processing.

[0065] In this embodiment, by setting up an encryption module and a UART communication connection, the data transmission between the main control module 1 and the conversion module 6 is effectively secured. The application of the encryption module makes it difficult for the transmitted data to be intercepted and parsed without authorization, thereby avoiding the leakage of sensitive information. At the same time, the stability of the UART communication connection also ensures the accuracy and reliability of data transmission, which not only improves the data security of the attendance and access control integrated machine, but also enhances the stability and reliability of the entire system, providing users with a safer and more reliable access control management solution.

[0066] like Figure 4 , Figure 5 , Figure 6 and Fig.11As shown, in a preferred example, the data transmission module 401 includes a wired transmission module 402 and a wireless transmission module 403 .

[0067] The wireless transmission module 403 includes at least one of a wireless network module 404 , a Bluetooth module 405 , and a near field communication module 406 (NFC module).

[0068] In the attendance and access control integrated machine, the data transmission module 401 integrates both wired transmission and wireless transmission to meet the data transmission requirements in different scenarios. The wireless transmission module 403 includes a wireless network module 404, a Bluetooth module 405, a near field communication module 406 (NFC module), etc. These modules can be selected and configured according to the actual application scenario. When data transmission is required, the main control module 1 selects the corresponding transmission module for data transmission according to the type and distance requirements of data transmission. The wireless transmission module 403 transmits data to the receiving end through wireless signals to achieve fast and convenient data exchange.

[0069] The data transmission module 401 adopts a combination of wired and wireless modes, and can select different attendance modes or access lock 7 switch modes, which greatly improves the data transmission efficiency and flexibility of the attendance and access control integrated machine. The diverse selection of wireless transmission modules 403 allows the system to be flexibly configured according to actual needs and adapt to different working environments and data transmission requirements. At the same time, the wireless transmission method reduces the cumbersome wiring, reduces system costs, and improves the convenience of data transmission.

[0070] like Figure 1 As shown, in a preferred embodiment, the expansion module 4 includes an audio interface module 407, and the audio interface module 407 is connected to a speaker and a microphone.

[0071] When voice prompt or voice interaction is needed, the main control module 1 sends an audio signal to the speaker through the audio interface module 407, and the speaker plays the prompt sound or interactive voice. At the same time, the microphone can capture the surrounding sound signals and transmit them to the main control module 1 for processing through the audio interface module 407.

[0072] In this embodiment, by setting the audio interface module 407 on the main control module 1 and connecting the speaker and the microphone, the attendance and access control integrated machine realizes the functions of voice interaction and voice prompt, which greatly improves the user experience. The voice prompt function can clearly convey information such as access control status and attendance results to the user, reducing the steps for the user to view the display screen or operate other devices. The voice interaction function allows the user to control the switch of the access control through voice commands, further simplifying the operation process, not only improving the convenience of the access control system, but also enhancing the interactivity between the user and the device, making the attendance and access control integrated machine more in line with the needs of modern intelligence.

[0073] like Figure 1 As shown, in a preferred embodiment, the expansion module 4 includes a video interface module 408, and the video interface module 408 is connected to a display screen.

[0074] When the attendance and access control integrated machine is running, the main control module 1 will send corresponding video signals to the display screen through the video interface module 408 according to the current working status and the information to be displayed. After receiving these signals, the display screen will display images, text or animations in real time, providing users with intuitive and clear visual feedback.

[0075] In this embodiment, by setting the video interface module 408 on the main control module 1 and connecting the display screen, the attendance and access control integrated machine realizes efficient and intuitive information display. The addition of the display screen not only improves the interactivity of the device, allowing users to obtain the required information more conveniently, but also enhances the visualization of the device, making access control management and attendance work more transparent and easy to monitor.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
