Under such an understanding, various specific lower-level specific definitions of the nouns or methods should be regarded as the content of the present utility model of the present utility model, and should not be narrowly understood or prejudicially interpreted on the grounds that the specific definition is not disclosed in the specification. Similarly, on the premise that it can be logically realized, the order of the steps in the method is flexible and changeable, and the specific lower-level specific definitions in the broad concepts of various nouns or methods belong to the protection scope of the present utility model.

[0046] The main solution of the embodiment of the present application is as follows: An image acquisition circuit is provided to acquire the image of the environment where the user is currently located and output the corresponding image signal. Then, a control circuit is electrically connected to the image acquisition circuit to generate a corresponding recognition signal according to the image signal and a preset image model. Finally, a vibration indication circuit is provided and connected to the output end of the control circuit to perform a corresponding indication action according to the recognition signal.

[0047] In the prior art, during the information transmission process, all the recognized information is completely transmitted to the blind user. This may lead to the blind being faced with the dilemma of information overload and making it difficult to quickly and effectively process all the received information. In addition, the way of voice prompt may interfere with the natural communication between the blind and the surrounding environment in some cases, thus posing a potential threat to the travel safety of the blind.

[0048] The present application provides a solution to ensure that the blind user can efficiently and safely obtain and process the key information of the surrounding environment, reduce unnecessary information interference, ensure the travel safety of the blind user, and improve the travel experience.

[0049] Refer to Figure 1 In an embodiment of the present utility model, the blind guiding device includes an image acquisition circuit 100, a control circuit 200, and a vibration indication circuit 300, where:

[0050] The image acquisition circuit 100 is used to acquire the image of the environment where the user is currently located and output the corresponding image signal; the input end of the control circuit 200 is connected to the output end of the image acquisition circuit 100, and the control circuit 200 is used to generate a corresponding recognition signal according to the image signal and a preset image model; the controlled end of the vibration indication circuit 300 is connected to the output end of the control circuit 200, and the vibration indication circuit 300 is used to perform a corresponding indication action according to the recognition signal.

[0051] In this embodiment, the image acquisition circuit 100 can be a high-definition camera module with night vision function and wide-angle view, which can clearly capture the details of the user's surrounding environment and ensure the accuracy and integrity of the image signal both during the day and at night.

[0052] The control circuit 200 can be implemented by a main controller 210, such as an MCU (Microcontroller Unit), a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), an SOC (System On Chip), etc. It can also be implemented by an advanced image processing chip, which has an efficient algorithm library built-in and can analyze and process the received image signals in real time. By comparing with a preset image model, the control circuit 200 can quickly identify key information in the environment, such as obstacles, traffic signals, pedestrian movements, etc., and generate corresponding recognition signals accordingly. These recognition signals not only have high accuracy but also fast response speed, ensuring that blind users can immediately obtain important changes in the surrounding environment.

[0053] The vibration indication circuit 300 is designed to be both sensitive and reliable. It can generate vibrations with different frequencies and intensities according to the recognition signals of the control circuit 200 to simulate different indication actions. For example, when an obstacle is detected ahead, the vibration indication circuit 300 will emit a rapid and strong vibration to remind the user to pay attention and avoid; when the green light is recognized, it will emit a continuous and stable vibration to guide the user to pass through the intersection safely. This vibration prompt method is not only intuitive and easy to understand but also avoids the possible interference caused by voice prompts, allowing blind users to focus more on the perception and judgment of the surrounding environment, reducing unnecessary information interference and potential safety hazards, and providing a safer, more convenient and comfortable experience for blind users' travel.

[0054] In addition, users can adjust the trigger conditions of the recognition signals and the feedback methods of the vibration prompts according to their travel habits and preferences. For example, some users may be more concerned about potholes and steps on the road surface, while others may be more concerned about traffic signals and pedestrian movements. Through the user-defined function, the blind guidance device can better meet the needs of users and provide more considerate and personalized services.

[0055] In this embodiment, an image acquisition circuit 100 is provided to acquire the image of the user's current environment and output the corresponding image signal. Then, a control circuit 200 is electrically connected to the image acquisition circuit 100 to generate corresponding recognition signals according to the image signal and the preset image model. Finally, a vibration indication circuit 300 is provided and connected to the output end of the control circuit 200 to perform corresponding indication actions according to the recognition signals, so as to ensure that blind users can efficiently and safely obtain and process key information in the surrounding environment, reduce unnecessary information interference, ensure the travel safety of blind users, and improve the travel experience.

[0056] Optionally, referring to Figure 2 , another embodiment of the present utility model provides a blind guiding device. Based on the above Figure 1 -shown embodiment, the image acquisition circuit 100 includes a camera module 110, where:

[0057] The output end of the camera module 110 is connected to the input end of the control circuit 200. The camera module 110 is used to collect the image of the environment where the user is currently located and output the corresponding image signal.

[0058] In this embodiment, the camera module 110 may include a camera and a lens. The camera is built-in with a high-sensitivity sensor to ensure clear images can be captured even in low-light environments. The lens adopts a wide-angle design to cover a wider field of view, reduce the blind spot of the field of view, and enable blind users to understand the surrounding environment more comprehensively. At the same time, the surface of the lens is covered with an anti-fog and dust-proof coating to ensure clear shooting effects under various weather conditions.

[0059] In addition, the camera module 110 can also be equipped with autofocus and image stabilization technologies. The autofocus function can quickly adjust the lens focal length to ensure that the captured images are always clear and sharp; while the image stabilization technology can effectively reduce the impact of vibrations generated during walking on the image quality and provide a more stable visual effect.

[0060] Optionally, referring to Figure 3 , another embodiment of the present utility model provides a blind guiding device. Based on the above Figure 1 -shown embodiment, the control circuit 200 includes a main controller 210 and a memory 220, where:

[0061] The input end of the main controller 210 is connected to the output end of the image acquisition circuit 100, and the output end of the main controller 210 is connected to the controlled end of the vibration indication circuit 300. The main controller 210 is used to generate a corresponding recognition signal according to the image signal and a preset image model; the memory 220 is electrically connected to the main controller 210, and the memory 220 is used to store the image data output by the main controller 210 and the preset image model, or the corresponding image in the preset image model to the main controller 210.

[0062] In this embodiment, the main controller 210 can be implemented using an MCU (Microcontroller Unit), a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), an SOC (System On Chip), etc., or an advanced image processing chip. These high-performance hardware options ensure that the main controller 210 can efficiently and accurately process image data. The main controller 210 is not only responsible for receiving image signals from the image acquisition circuit 100, but also has a powerful algorithm library built-in, which can quickly obtain the preset image models stored in the memory 220 for comparison and analysis. This comparison process can be completed in an instant, ensuring that blind users can immediately obtain key information about the surrounding environment.

[0063] The memory 220 uses a high-speed and large-capacity storage medium, such as Flash Memory or a Solid State Drive (SSD), to ensure that it can store a large amount of image data and complex preset image models. These image data may include image samples under different lighting conditions and different environmental backgrounds, while the preset image models may be trained based on deep learning or machine learning algorithms and can accurately identify key elements in various scenarios, such as obstacles, traffic signs, pedestrians, etc. The data transmission between the main controller 210 and the memory 220 is achieved through a high-speed bus interface, ensuring the efficiency and stability of data transmission.

[0064] The memory 220 can not only store the image data output by the main controller 210 to provide data support for subsequent analysis and processing, but also stores multiple preset image models. These models cover various common travel scenarios, such as streets, parks, intersections, etc., and each model corresponds to a specific recognition logic and vibration feedback mode. When the main controller 210 detects an image signal that matches a certain preset model, it will immediately generate a corresponding recognition signal and send a clear indication to the blind user through the vibration indication circuit 300.

[0065] In addition, the memory 220 also supports a dynamic update function. With the continuous progress of technology and the increasing complexity of the travel environment, the preset image models need to be continuously optimized and improved. By connecting and synchronizing with other intelligent devices, the memory 220 can receive and update the latest image models in real time, ensuring that the guiding device always maintains the best working state. This dynamic update mechanism not only improves the adaptability and flexibility of the guiding device, but also provides strong guarantee for its long-term use.

[0066] Optionally, refer to Figure 4, yet another embodiment of the present utility model provides a blind guiding device. Based on the above Figure 1 shown embodiment, the blind guiding device further includes a signal conversion circuit 400, wherein:

[0067] The signal conversion circuit 400 is serially disposed between the control circuit 200 and the vibration indication circuit 300. The signal conversion circuit 400 is configured to convert the identification signal generated by the control circuit 200 into a corresponding operation coding signal and output it to the vibration indication circuit 300.

[0068] In this embodiment, the signal conversion circuit 400 can be implemented by a dedicated coding converter or a coding conversion module integrated in the control circuit 200, ensuring that the identification signal output by the control circuit 200 can be accurately converted into an operation coding signal that the vibration indication circuit 300 can understand and execute. Among them, the signal conversion circuit 400 decodes, encodes, and converts the format of the identification signal to adapt to the working requirements and interface standards of the vibration indication circuit 300. Among them, the operation coding signal not only includes the specific types of indication actions (such as vibration frequency, vibration intensity, vibration mode, etc.), but may also include other auxiliary information, such as the urgency level and duration of the indication. These information are packaged into the operation coding signal through a carefully designed coding scheme, ensuring the integrity and accuracy of the information, and improving the stability and reliability of the blind guiding device.

[0069] Optionally, referring to Figure 5 , yet another embodiment of the present utility model provides a blind guiding device. Based on the above Figure 1 shown embodiment, the vibration indication circuit 300 includes a driving circuit 310 and a vibration motor 320, wherein:

[0070] The controlled end of the driving circuit 310 is connected to the output end of the control circuit 200; the controlled end of the vibration motor 320 is connected to the control end of the driving circuit 310; the driving circuit 310 is configured to drive the vibration motor 320 to act according to the identification signal.

[0071] In this embodiment, the driving circuit 310 can be an electronic circuit integrated with high-precision power control function. It can receive the identification signal from the control circuit 200 and, based on the instruction information in the signal, precisely adjust the current or voltage output to the vibration motor 320, thereby realizing fine control of the vibration motor 320. The driving circuit 310 may internally include key components such as an amplifier, a current source, and a PWM (pulse width modulation) controller. These components work together to ensure that the vibration motor 320 can perform accurate and stable vibration output according to the preset vibration mode, frequency, and intensity.

[0072] The selection of the vibration motor 320 is crucial for enhancing the user experience. It can adopt a high-performance linear motor or an eccentric rotor motor, which have the advantages of fast response speed, good vibration effect, and low noise. Through the precise control of the drive circuit 310, the vibration motor 320 can simulate various different vibration effects, such as short touches, continuous vibrations, vibration waves of different frequencies, etc., providing intuitive and rich environmental information for blind users.

[0073] In addition, after detecting the ambient noise, the output of the vibration indication circuit 300 can be dynamically adjusted. For example, when it is detected that the user is in a noisy environment, the intensity and frequency of the vibration can be automatically increased to ensure that the user can clearly perceive the indication signal; while when the user is in a quiet or resting state, the intensity of the vibration can be correspondingly reduced to avoid unnecessary interference to the user, which can more intelligently and efficiently assist blind users in understanding the surrounding environment and improve their travel safety.

[0074] Optionally, referring to Figure 6 , another embodiment of the present utility model provides a blind guiding device. Based on the above Figure 1 illustrated embodiment, the blind guiding device further includes a battery 500, wherein:

[0075] The battery 500 is respectively connected to the image acquisition circuit 100, the control circuit 200, and the vibration indication circuit 300, and the battery 500 is used for power supply.

[0076] In this embodiment, the battery 500 serves as the energy source of the entire blind guiding device. In order to ensure that the blind guiding device can work stably for a long time, while taking into account portability and safety, a lithium battery 500 with high energy density and long life can be adopted as the power supply solution. This battery 500 not only has excellent discharge performance and can quickly provide sufficient power support for each circuit module, but also has the characteristic of light weight, reducing the weight of the entire device and facilitating blind users to carry it with them. In addition, the lithium battery 500 also has a low self-discharge rate, and can maintain the battery power for a long time even when not in use, extending the standby time of the device.

[0077] In order to improve the usage efficiency and safety of the battery 500, this embodiment can also be integrated with an intelligent battery 500 management system (BMS). The BMS can real-time monitor key parameters such as the voltage, current, and temperature of the battery 500 to ensure that the battery 500 always works within a safe range. When the battery 500 power is too low, the BMS will promptly issue an alarm to remind the user to charge; at the same time, during the charging process, the BMS can also effectively control the charging current and voltage to prevent the battery 500 from overcharging or over-discharging, extending the service life of the battery 500. In addition, the BMS also has multiple safety functions such as short-circuit protection, over-current protection, and temperature protection, providing comprehensive safety protection for blind users.

[0078] In the design of the battery 500, the battery 500 can also adopt a standardized interface design, enabling users to easily replace the battery 500 without the need for professional tools or skills. At the same time, in order to extend the service life of the battery 500 and reduce its impact on the environment, this embodiment also encourages users to adopt rechargeable lithium batteries 500 and provides convenient charging methods, such as charging through a USB interface by connecting to a power bank or a computer, which is convenient and fast.

[0079] Optionally, referring to Figure 7 , another embodiment of the present utility model provides a blind guiding device. Based on the above Figure 1 illustrated embodiment, the blind guiding device further includes a wireless charging device 600, where:

[0080] The output end of the wireless charging device 600 is connected to the input end of the battery 500, and the wireless charging device 600 is used to charge the battery 500.

[0081] In this embodiment, considering the charging inconvenience problem that blind users may face, the design of the wireless charging device 600 fully considers usability and safety. Through the principle of electromagnetic induction, this device realizes the function of charging the battery 500 without physical contact, greatly simplifying the charging process and avoiding the cumbersome and inconvenient aspects that traditional wired charging may bring. The wireless charging device 600 generally includes a transmitting end and a receiving end. The transmitting end can be designed as a small charging pad or charging base, placed in a place easily accessible to users, such as beside the bed, on the desk, or inside a backpack. The receiving end is integrated into the battery 500 part of the blind guiding device, and through the built-in receiving coil, it couples with the magnetic field of the transmitting end to achieve wireless power transmission. The entire charging process requires no manual intervention. Users only need to place the blind guiding device on the charging pad, and charging will start automatically, which is both safe and efficient.

[0082] The present utility model also proposes a wearable device, which includes a wearable main body 700 and a blind guiding device as described in the above embodiment, and the blind guiding device is connected to the wearable main body 700.

[0083] It should be noted that since the wearable device of the present utility model is based on the above-mentioned blind guiding device, therefore, the embodiments of the wearable device of the present utility model include all the technical solutions of all the embodiments of the above-mentioned blind guiding device, and the achieved technical effects are also exactly the same, which will not be elaborated here.

[0084] Optionally, referring to Figure 8, an embodiment of the present utility model provides a wearable device, wherein the vibration indication circuit 300 includes a plurality of vibration motors 320; the plurality of vibration motors 320 are installed at multiple positions of the wearable body 700; when the control circuit 200 outputs an identification signal, it controls the corresponding vibration motor 320 to act to provide the corresponding vibration prompt information to the user.

[0085] In this embodiment, the wearable body 700 can be in the form of any device suitable for blind users to wear, such as gloves, bracelets, hats or glasses. By installing a plurality of vibration motors 320 on these wearable bodies 700 and distributing them at different positions, more abundant and delicate tactile feedback can be provided to the user. This distributed vibration design not only enables the user to perceive vibration prompts from different directions, but also can simulate more complex vibration patterns, such as direction guidance and obstacle avoidance, through the combined operation of vibration motors 320 at different positions, greatly improving the transmission efficiency and accuracy of information.

[0086] Among them, after receiving the identification signal from the image acquisition circuit 100 or an external sensor, the control circuit 200 will quickly analyze and determine the corresponding vibration prompt strategy. The control circuit 200 will precisely control the startup timing, vibration frequency and intensity of each vibration motor 320, so as to generate a specific vibration effect at the corresponding position of the wearable body 700. For example, during navigation, when an obstacle is detected ahead, the control circuit 200 can drive the vibration motor 320 located in front of the wearable body 700 to vibrate rapidly to remind the user to pay attention and change the traveling direction; and when the user needs to confirm the current position or direction, the direction indication can be formed by the alternating vibration of vibration motors 320 at different positions to help the user establish a sense of space.

[0087] In the design of the wearable body 700, this embodiment also pays attention to comfort and durability. The wearable body 700 is made of a soft and breathable material to ensure that it will not cause discomfort to the user even after long-term wearing. At the same time, in order to cope with various complex usage scenarios, the wearable body 700 has also undergone strict waterproof, dustproof and drop-resistant tests to ensure stable working performance in various harsh environments.

[0088] Optionally, referring to Figure 9 , another embodiment of the present utility model provides a wearable device, wherein a wireless communication circuit 800 is provided on the wearable body 700, and the wireless communication circuit 800 is electrically connected to the user's smart terminal and the cloud platform respectively.

[0089] In this embodiment, the wireless communication circuit 800, as an important bridge for the wearable device to interact with the external environment, not only enhances the intelligence of the device but also greatly improves the user experience. The wireless communication circuit 800 supports multiple communication protocols such as Bluetooth, Wi-Fi, NFC, etc., ensuring seamless connection with various intelligent terminals and cloud platforms.

[0090] First, through Bluetooth connection, the wearable device can transmit data in real time with intelligent terminals such as the user's smartphone and smartwatch. This short-range wireless communication method not only has low power consumption and stable connection but also enables fast data synchronization and interaction. The family members of blind users can view information such as the working status of the blind guiding device, the battery 500 power, and historical navigation records through the APP on the intelligent terminal, and can even remotely control and set the blind guiding device. Secondly, Wi-Fi connection allows the wearable device to access the Internet and achieve broader data sharing and interaction with the cloud platform. Through big data analysis and machine learning algorithms, the cloud platform can continuously optimize the environment recognition ability, navigation algorithm, and user experience of the blind guiding device. For example, the cloud platform can recommend more suitable routes for users based on their historical navigation records and preferences, or send early warning messages to users in advance by analyzing external factors such as traffic conditions and weather changes in real time. At the same time, the cloud platform also provides remote upgrade services to ensure that the wearable device can obtain the latest software updates and function upgrades at any time. Finally, the application of NFC (Near Field Communication) technology enables the wearable device to show greater potential in scenarios such as payment and access control. Users can complete operations such as payment and punching with a simple touch, without the need to carry additional cards or devices. This convenience not only improves the user experience but also reduces the risk of losing or forgetting items.

Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.
