[0050] It should be understood that the specific embodiments described herein are merely intended to explain the technical solutions of the present application, and are not intended to limit the present application.

[0051] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0053] In addition, the description of "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of those of ordinary skill in the art, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection claimed by the present application.

[0054] It can be understood that, as people's health awareness improves, the demand for real-time monitoring of physiological parameters such as blood pressure is increasing.

[0055] The conventional blood pressure measurement method mainly relies on a sphygmomanometer, which requires a specific measurement environment and operation steps and cannot realize convenient monitoring anytime and anywhere. As a common smart wearable device, smart glasses have the characteristics of convenient wearing and convenient use. Therefore, how to enable smart glasses to have a blood pressure monitoring function is a technical problem to be solved.

[0056] Therefore, in order to solve the above defects, the embodiment provides a smart glasses. Since the pulse generated by the heartbeat causes a slight movement on the skin surface, a blood pressure monitoring circuit can be arranged at the temple in the embodiment, and a radar signal is emitted to the skin corresponding to the blood vessel region of the wearer by the blood pressure monitoring circuit. The pulse wave signal of the wearer in the region is collected by using the radar signal, and is fed back to the blood pressure monitoring circuit in the form of a reflected signal. The blood pressure monitoring circuit determines the blood pressure value of the wearer according to the pulse wave signal in the received reflected signal, so that the smart glasses have the function of blood pressure monitoring.

[0057] For the convenience of understanding, the following will be combined with Figures 1 to 4 The smart glasses provided by the embodiment of the application will be specifically introduced.

[0058] Referring to Figure 1 , Figure 1 is a structural schematic view of the first embodiment of the smart glasses of the application. The first embodiment of the smart glasses of the application is proposed, as shown in Figure 1 , the smart glasses comprise:

[0059] a frame;

[0060] a temple, the temple is arranged on the frame.

[0061] It should be noted that the smart glasses in the embodiment can be any smart glasses with an integrated circuit, such as virtual reality (VR) glasses, augmented reality (AR) glasses, etc. The embodiment does not limit this. The structure of the smart glasses in the embodiment can be consistent with the general structure of glasses, and can comprise a frame and two temples, as shown in Figure 1 , one temple can be arranged on each side of the frame to support the smart glasses to be worn on the eye of the wearer.

[0062] It can be understood that, in order to realize blood pressure monitoring, as shown in Figure 1 , the smart glasses can further comprise a blood pressure monitoring circuit in the embodiment, the blood pressure monitoring circuit is arranged on the temple, and the blood pressure monitoring circuit is used to emit a radar signal to the skin corresponding to the blood vessel region of the wearer, and to determine the blood pressure value of the wearer according to the pulse wave signal in the received reflected signal.

[0063] The radar signal can be used to collect a pulse wave signal of a blood vessel of the wearing user. The pulse wave signal can be a signal of a pulse of the wearing user. Due to the heartbeat of the wearing user, the pulse can drive a slight vibration of the blood vessel (i.e., a pulse fluctuation caused by the heartbeat), and then drive a slight vibration of the skin surface. The blood pressure monitoring circuit in the embodiment can emit a radar signal to a blood vessel region of the wearing user to collect the slight vibration of the skin surface of the blood vessel region, and obtain the pulse of the wearing user.

[0064] The blood vessel region can be a region where the blood vessel of the wearing user is distributed. Since the embodiment is applied to the smart glasses, the positions of the blood pressure monitoring circuit can be regions where the blood vessels are distributed around the eyes of the wearing user when the smart glasses are worn by the user. The embodiment is not limited in this regard.

[0065] The reflection signal can be a signal fed back by the skin vibration after the radar signal is received by the blood vessel region of the wearing user. Due to the expansion and contraction of the blood vessel due to the heartbeat, the pulse changes, and the reflection signal also changes. Therefore, the embodiment can extract the pulse wave signal in the reflection signal after receiving the reflection signal, and obtain the pulse waveform of the wearing user. The blood pressure value of the wearing user can be determined according to the pulse wave signal.

[0066] Therefore, when the user wears the smart glasses in actual use, the blood pressure monitoring circuit in the smart glasses can emit a radar signal to the blood vessel region of the wearing user, receive the feedback reflection signal, and determine the blood pressure value of the wearing user according to the pulse waveform in the reflection signal, so that the smart glasses have the blood pressure monitoring function.

[0067] Further, in order to make the blood pressure monitoring circuit emit the radar signal and determine the blood pressure value according to the reflection signal, refer to Figure 2 , Figure 2 The structure block diagram of the blood pressure monitoring circuit in the first embodiment of the smart glasses of the present application is shown in FIG. 1. As shown in FIG. 1, in the embodiment, the blood pressure monitoring circuit comprises a radar module and a conversion module. Figure 2 The conversion module is connected with the radar module.

[0068] The radar module is used to emit the radar signal to the skin corresponding to the blood vessel region of the wearing user, and transmit the received reflection signal to the conversion module.

[0069] The conversion module is used to convert the pulse wave signal in the reflection signal into a blood pressure signal, and the blood pressure signal is used to determine the blood pressure value of the wearing user.

[0070] The conversion module is used to convert the pulse wave signal in the reflection signal into a blood pressure signal, and the blood pressure signal is used to determine the blood pressure value of the wearing user.

[0071] It should be understood that the aforementioned radar module can be a module that transmits radar signals. In order to collect the pulse wave signal of the wearer, the radar signal in this embodiment can be a millimeter-wave radar signal. Since the wavelength of millimeter-wave radar signals is generally 1 mm to 10 mm and the frequency is generally 30 GHz to 300 GHz, it is possible to accurately collect vascular vibrations.

[0072] Therefore, in order to generate millimeter-wave radar signals, the radar module in this embodiment may include a millimeter-wave radar. Specifically, the model of the millimeter-wave radar can be set according to actual conditions, and this embodiment does not impose any restrictions on it.

[0073] It is important to emphasize that, in this embodiment, the radar signal is emitted to the skin of the user's vascular area, which is generally rich in blood vessels near the temples, making it easy to collect data. Therefore, continuing as follows... Figure 1 As shown, in this embodiment, the radar module (i.e. Figure 1 The mid-millimeter-wave radar can be positioned inside the temple of the glasses, corresponding to the skin of the blood vessel area at the wearer's temple. The specific location corresponding to the temple can be set according to actual conditions; this embodiment does not impose any restrictions, only requiring that the transmitted radar signal covers part of the blood vessels at the temple. Furthermore, the blood pressure monitoring circuit in this embodiment can be located inside any temple of the smart glasses; this embodiment does not impose any restrictions on this.

[0074] It should be noted that the aforementioned conversion module can be any module with signal conversion capabilities. The aforementioned blood pressure signal can be a signal used to determine the blood pressure value of the wearer. In this embodiment, since the reflected signal received by the millimeter-wave radar is not a recognizable blood pressure signal, this embodiment can use a conversion module to convert the analog reflected signal into a digital blood pressure signal for identification.

[0075] Meanwhile, since the reflected signal may be weak and contain a lot of interference, the conversion module in this embodiment can first amplify and filter the reflected signal, then perform analog-to-digital conversion on the processed reflected signal, and then analyze the analog-to-digital converted reflected signal to obtain a blood pressure signal that can determine the blood pressure value.

[0076] Further, in an embodiment, an operational amplifier can be arranged in the conversion module to amplify the reflected signal, a low-pass filter can be arranged to filter the amplified reflected signal, and an analog-to-digital converter can be arranged to perform analog-to-digital conversion on the filtered reflected signal to obtain an analog-to-digital converted reflected signal. After obtaining the analog-to-digital converted reflected signal, the conversion module can determine the blood pressure value of the wearing user according to the blood pressure signal. Specifically, a digital signal processor (DSP) can be arranged in the conversion module, and the digital signal processor can extract a blood pressure related characteristic parameter (i.e., the pulse wave signal) from the analog-to-digital converted reflected signal according to a preset algorithm (e.g., Fourier transform, wavelet transform), and then a preset model can be used to obtain the blood pressure value according to the characteristic parameter and generate a corresponding blood pressure signal.

[0077] It should be emphasized that the above-mentioned manner of generating a blood pressure signal according to a reflected signal in the present embodiment can also be implemented by other manners, which are not limited in the present embodiment. Meanwhile, the manner of generating a blood pressure signal according to a reflected signal in the present embodiment belongs to the prior art, and those skilled in the art can implement it on the basis of the content of the present embodiment and the prior art, so the present embodiment does not elaborate on it.

[0078] It should also be emphasized that, in order to integrate the blood pressure monitoring circuit in the present embodiment into the temple of the smart glasses, the system in package (SIP) manner can be used in the present embodiment to reduce the volume and weight of the device.

[0079] In a specific implementation, when the user wears the smart glasses, the millimeter wave radar can emit a radar signal to the skin of the blood vessel region near the temple of the wearing user, then receive the feedback reflected signal and transmit it to the conversion module. After processing, the conversion module can convert the pulse wave signal in the reflected signal into a blood pressure signal to determine the blood pressure value of the wearing user.

[0080] Further, in order to provide power support for the blood pressure monitoring circuit, as shown in Figure 2 In the present embodiment, the smart glasses further include a power module.

[0081] The power module is connected with the blood pressure monitoring circuit.

[0082] The power module is configured to supply power to the blood pressure monitoring circuit.

[0083] It should be noted that the power module in the embodiment can adopt a rechargeable battery (for example, a lithium ion battery) and the like, and the power module can be connected with each module in the blood pressure monitoring circuit to supply power. Meanwhile, since the voltages required by each module can be different, a voltage conversion unit can be arranged in the power module in the embodiment, and the voltage conversion unit is connected with the rechargeable battery and each module in the blood pressure monitoring circuit to realize voltage conversion and supply power.

[0084] In the embodiment, the blood pressure monitoring circuit can be arranged at the temple, and radar signals are emitted to the skin corresponding to the blood vessel region of the wearing user by the blood pressure monitoring circuit. The pulse wave signal of the wearing user in the region is collected by using the radar signals, and is fed back to the blood pressure monitoring circuit in the form of a reflected signal. The blood pressure monitoring circuit determines the blood pressure value of the wearing user according to the pulse wave signal in the received reflected signal, so that the smart glasses provided in the embodiment have the function of blood pressure monitoring.

[0085] Meanwhile, since the blood pressure measurement is completed by using the millimeter wave radar in the embodiment, contactless measurement can be realized, and the discomfort and potential harm to the human body are reduced,

[0086] Reference Figure 3 , Figure 3 The structure block diagram of the blood pressure monitoring circuit in the second embodiment of the smart glasses of the application is shown in FIG. 2B. Based on the first embodiment, the second embodiment of the smart glasses of the application is proposed.

[0087] In order to store the blood pressure value of the wearing user, as shown in FIG. 2B, the blood pressure monitoring circuit in the embodiment further comprises a main control module. Figure 3

[0088] The main control module is connected with the conversion module.

[0089] The conversion module is configured to transmit the blood pressure signal to the main control module.

[0090] The main control module is configured to store the blood pressure value corresponding to the blood pressure signal.

[0091] It should be noted that the main control module can be a module for storing the blood pressure value of the wearing user. For example, it can be a microcontroller unit (MCU) or the like, and of course, it can also be other units, which are not limited in the embodiment.

[0092] It should be further noted that the main control module and the conversion module can be connected by a wired manner in the embodiment, and of course, they can also be connected by a wireless manner (for example, Bluetooth and the like), which are not limited in the embodiment.

[0093] ​It can be understood that in order to supply power to the master module, the power module in the embodiment can also be connected with the master module to realize power supply.

[0094] In actual use, after the conversion module obtains the blood pressure signal, the blood pressure signal can be transmitted to the master module. The master module can store the blood pressure value corresponding to the blood pressure signal, and then when the user needs to know the blood pressure in the subsequent wearing, the master module can read the stored blood pressure value and prompt the user through broadcasting, display or sending to the mobile terminal (such as mobile phone) of the wearing user.

[0095] Further, in order to enable the radar module to emit the radar signal, in the embodiment, the master module is also used to transmit the generated working signal to the radar module through the conversion module;

[0096] The radar module is also used to emit the radar signal to the skin corresponding to the blood vessel area of the wearing user when receiving the working signal.

[0097] It should be understood that the above working signal can be a signal indicating that the radar module is in a working state. In the embodiment, if the conversion module includes the above-mentioned DSP, a communication interface can be reserved to connect with the master module and the radar module. The master module can transmit the generated working signal to the conversion module through the communication interface, and the conversion module can transmit the working signal to the radar module through the communication interface. The radar module can output the radar signal after receiving the working signal.

[0098] Further, in order to reduce power consumption, the master module in the embodiment can use an MCU with low power consumption. When blood pressure monitoring is not needed, the master module is generally in a low power consumption state, and when blood pressure monitoring is needed, the master module can be switched from the low power consumption state to the working state.

[0099] In order to switch from the low power consumption state to the working state to generate the above-mentioned working signal when the wearing user needs to monitor the blood pressure, in the embodiment, as shown in Figure 3 The blood pressure monitoring circuit further includes a voice wake-up module.

[0100] The voice wake-up module is connected with the master module.

[0101] The voice wake-up module is used to collect external environmental sound and transmit the generated wake-up signal to the master module.

[0102] The master module is also used to transmit the generated working signal to the conversion module when receiving the wake-up signal.

[0103] It should be noted that the above wake-up signal can be a signal capable of switching the main control module from the low-power state to the working state. The above voice wake-up module can be a module with external environment sound collection and recognition. In this embodiment, when the user wearing has a blood pressure monitoring demand, the preset wake-up word (for example: "Xiao X, check blood pressure.") can be spoken, and the voice wake-up module can collect external environment sound and recognize it.

[0104] When the external environment sound contains the above preset wake-up word, it indicates that the user wearing has a blood pressure monitoring demand at this time, and then the voice wake-up module generates a wake-up signal and transmits it to the main control module. After receiving the wake-up signal, the main control module can be switched from the low-power state to the working state, and a working signal can be generated and transmitted to the conversion module when switching to the working state, and then transmitted to the radar module to emit a radar signal for blood pressure monitoring.

[0105] When the external environment sound does not contain the above preset wake-up word, it indicates that the user wearing does not have a blood pressure monitoring demand at this time, and then the voice wake-up module does not generate a wake-up signal, and the main control module continues to maintain the low-power state, and the radar module does not emit a radar signal.

[0106] It should also be noted that in order to power the voice wake-up module, the power module can also be connected to the voice wake-up module for power supply in this embodiment.

[0107] It should be emphasized that when the main control module generates a working signal, it can start timing, and when the current timing duration reaches a preset duration, it can be switched from the working state to the low-power state, thereby reducing power consumption. The above-mentioned preset duration can be set according to actual conditions, and this embodiment does not limit it.

[0108] Further, in order to realize identification, as shown in Figure 3 , in this embodiment, the voice wake-up module includes a voice collection unit and an identification unit.

[0109] The identification unit is connected with the voice collection unit and the main control module respectively.

[0110] The voice collection unit is configured to collect external environment sound and transmit the generated audio signal to the identification unit.

[0111] The identification unit is configured to identify the external environment sound corresponding to the audio signal and transmit the generated wake-up signal to the main control module.

[0112] It is understood that the aforementioned voice acquisition unit can be a unit that collects ambient sounds, such as a microphone, and this embodiment does not limit this. The aforementioned recognition unit can be a unit with audio recognition functionality, such as a voice chip, and this embodiment does not limit this either.

[0113] To achieve audio acquisition, refer to Figure 4 , Figure 4 This is a circuit diagram of the voice acquisition unit in the second embodiment of the smart glasses of this application. Figure 4 As shown, in this embodiment, the above-mentioned voice acquisition unit includes: a microphone (MIC), a first capacitor (C1), a second capacitor (C2), and a first resistor (R1);

[0114] The first output of the microphone (MIC) Figure 4 The first pin of the microphone (MIC) is connected to the first terminal of the first capacitor C1, and the second terminal of the first capacitor C1 is connected to the recognition unit (i.e. Figure 4 The second output terminal of the microphone (MIC) is connected to the ICR MICP. Figure 4 The second pin of the microphone (MIC) is connected to the first end of the first resistor R1, the second end of the first resistor R1 is connected to the first end of the second capacitor C2, the second end of the first resistor R1 is also grounded, and the second end of the second capacitor C2 is connected to the recognition unit (i.e. Figure 4 (ICR MICN) connection.

[0115] In practical use, the microphone (MIC) can collect ambient sounds and transmit them as audio signals through its first and second output terminals to the recognition unit for identification. The recognition unit can then determine whether the preset wake-up word exists in the ambient sounds corresponding to the audio signal. If it does, a wake-up signal is generated and transmitted to the main control module; otherwise, no wake-up signal is generated.

[0116] It should be emphasized that the recognition unit in this embodiment can use a voice chip of model LD3320. Of course, other voice chips can also be used, and this embodiment does not limit this.

[0117] Furthermore, in order to broadcast blood pressure values, in this embodiment, the blood pressure monitoring circuit further includes: a broadcasting module;

[0118] The broadcast module is connected to the main control module;

[0119] The main control module is used to convert the blood pressure value into a broadcast signal and transmit the broadcast signal to the broadcast module;

[0120] The broadcasting module is used to broadcast the blood pressure value corresponding to the broadcasting signal when it receives the broadcasting signal.

[0121] It should be noted that the above-mentioned broadcast module can be a module with a speaker.

[0122] In actual use, after the main control module obtains the blood pressure value, it can convert the blood pressure value into a broadcast signal and transmit it to the broadcast module, which can then broadcast the blood pressure value based on the broadcast signal.

[0123] Furthermore, considering that the corresponding positions of the temples and radar modules may differ among different users after wearing the smart glasses in this embodiment, therefore, for ease of data collection, reference is made to... Figure 5 , Figure 5 This is a schematic diagram of the temple structure in the second embodiment of the smart glasses of this application. Figure 5 As shown, in this embodiment, the smart glasses further include:

[0124] slider;

[0125] A sliding groove is provided on the temple of the mirror;

[0126] The radar module is connected to the slider and slides along the length of the groove.

[0127] It should be noted that, referring to Figure 6 , Figure 6 This is a schematic diagram showing the connection between the slider and the radar module in the second embodiment of the smart glasses of this application. Figure 6 As shown, in this embodiment, the radar module can be disposed inside the temple, the slider can be disposed outside the temple, and the groove can be formed on the outer wall of the temple. The length of the groove can be set according to the actual situation, and this embodiment does not limit it.

[0128] In actual use, after the user wears the smart glasses, the user can manually push the slider to slide along the length of the groove, thereby causing the millimeter-wave radar to slide along the length of the groove, so that the millimeter-wave radar is aligned with the user's temple, thereby improving the accuracy of data collection.

[0129] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
