[0049] The following is combined with Figure 1-3 This application is described in further detail.

[0050] The embodiment of the present application discloses a monitoring method for a smart ring based on PPG physiological index monitoring.

[0051] Reference Figure 1-2 The monitoring method for a smart ring based on PPG physiological index monitoring includes: establishing a wireless communication relationship between the smart ring and a personal terminal, optimizing the configuration of the smart ring on the main body side, and optimizing the configuration of the personal terminal on the local side.

[0052] In this embodiment, the smart ring should at least be able to perform heart rate / pulse detection and establish a connection with a personal terminal via an integrated Bluetooth module; the personal terminal includes a mobile phone.

[0053] Among them, the local optimization configuration for personal terminals includes:

[0054] S11. Receive the original data uploaded by the smart ring.

[0055] In this embodiment, the detection signals output by the various sensors of the smart ring are not analyzed or processed in the smart ring, or are uploaded to the mobile phone after only a little analysis and processing, and the mobile phone performs more complex calculations to reduce the computing power consumption of the smart ring and extend the battery life.

[0056] S12. Process the raw data based on a preset PPG algorithm to obtain physiological index data.

[0057] The above-mentioned PPG is a standardized toolbox. The algorithm is used for finger photoplethysmography (PPG) analysis, including heartbeat detection, reference point detection and comprehensive evaluation of standard biomarkers. It is a prior art and will not be described in detail. This embodiment aims to use it to analyze blood oxygen, blood pressure, heart rate and other characteristics. Physiological indicator data can be: blood oxygen saturation, heart rate variability, blood pressure, etc.

[0058] S13. Perform health assessment based on physiological indicator data to obtain assessment data.

[0059] Health assessment, example: compare the real-time physiological indicator data with the standard reference range values ​​preset by the manufacturer. If it is within the standard reference range, it is healthy; if it exceeds the standard reference range, it is abnormal.

[0060] S14. If the evaluation data meets the preset suspected abnormal conditions, the original data upload conditions are adjusted based on the preset condition adjustment rules, and the new data upload conditions are sent to the smart ring.

[0061] Among them, suspected abnormal conditions are such as the conditions judged as abnormal in the above example, or other conditions close to being judged as abnormal, which are specifically set by the staff. Condition adjustment rules, example:

[0062] 1) The initial data upload condition is to upload at a frequency of t1 / time. When the suspected abnormal conditions are met, continuous transmission is performed until the continuous duration of t2 is healthy; t1 and t2 are preset values.

[0063] 2) The initial data upload condition is when the blood pressure is P1. When the suspected abnormal conditions are met, the new data upload condition is adjusted to blood pressure P2; P1 and P2 are preset values.

[0064] The local optimization configuration for the smart ring includes:

[0065] S21. If a new data upload condition is received, the data sent by the personal terminal is parsed using a preset parsing method to obtain a signal characteristic condition and / or an inherent attribute characteristic condition corresponding to the data upload condition.

[0066] As mentioned above, the smart ring in this embodiment does not perform complex algorithm analysis. Therefore, the data upload conditions need to be converted into signal features on the smart ring side to determine whether to upload the data by comparing the original signal features. Example: The PPG algorithm estimates blood pressure based on vasoconstriction features. At this time, the above analysis is to reversely deduce the vasoconstriction features based on blood pressure, that is, to deduce the signal features of the matching detection signal.

[0067] The above-mentioned inherent attribute characteristic conditions are conditions generated based on the inherent attributes of the device such as time and frequency as shown in the above examples.

[0068] S22. If the monitoring signal meets the signal characteristic condition and / or the fixed attribute characteristic condition, the monitoring signal is sent to the personal terminal; wherein the monitoring signal is generated after the sensing unit senses the user's finger.

[0069] According to the above content, this application uses the smart ring mainly as an information collection device, and implements complex calculations such as health assessment through a personal terminal (such as a mobile phone); at this time, the computing power requirements of the ring are relatively low, and the computing power consumption during use is lower; at the same time, the smart ring and the personal terminal do not communicate and transmit continuously, so the communication power consumption is also relatively lower, thereby improving the battery life of the smart ring.

[0070] In one embodiment of the method, considering that there is sufficient computing power support after applying the method and there is no need to consider the interference of computing power on battery life, the staff can also deepen the algorithm to identify arrhythmia, atrial fibrillation, premature beats, respiratory disorders and snoring;

[0071] At the same time, the VMD-SVD signal denoising method can be introduced in the signal processing process to optimize the denoising filtering process;

[0072] You can also extract features such as SDNN (standard deviation of all normal heart beat intervals (NN)), RMSSD (root mean square value of the difference between adjacent NN intervals), TP (total power), etc. and input them into the HRV (heart rate variability) analysis model for training to improve the accuracy of health assessment.

[0073] In another embodiment of the method, the smart ring and the personal terminal establish a communication relationship using a low-power Bluetooth module BLE; on this basis, the local side optimizes the configuration, which includes:

[0074] Get the communication signal strength, that is, the signal strength of BLE; it is known that the closer the distance, the stronger the strength;

[0075] The original data upload conditions are adjusted according to the communication signal strength; for example: when the signal strength is D1, the data is uploaded at a frequency of t1 / time; when the signal strength is D2, the data is uploaded at a frequency of t3 / time; wherein D1<D2, t1 is greater than t3.

[0076] The basis for the above setting is that the greater the distance, the smaller the received signal strength, and the greater the energy consumption to achieve the original signal transmission effect; and based on the application object of this application, the scenario that may occur is: the mobile phone is placed in the bedroom to charge, and people are active at home; in this scenario, the user is unlikely to check health data, so while maintaining efficacy, the frequency of data reporting (uploading) can be reduced to reduce working energy consumption.

[0077] Furthermore, the local side optimization configuration also includes:

[0078] Identify the user's current behavior scenario based on physiological indicator data; for example, a healthy sleep scenario is identified when the heart rate is steady and stable; a risky sleep scenario is identified when snoring occurs.

[0079] Actively assign and modify the communication signal strength according to the behavioral scenario; based on the above example: in the healthy sleep scenario, the original signal strength is D1, and the signal strength is set to D1 at this time; in the risky sleep scenario, the original signal strength is D1, and the signal strength is set to D2 at this time.

[0080] According to the above settings, when adjusting the data upload conditions based on signal strength, this method will also analyze the user's behavior scenario and adjust again according to the behavior scenario to reduce energy consumption and ensure the safety of health monitoring.

[0081] In one embodiment of the method, the body side optimization configuration further includes:

[0082] Identify the PID (i.e., product ID) parsed from the communication broadcast data;

[0083] Identify the PIDs belonging to the same user and obtain only the communication signal strength corresponding to the PID.

[0084] According to the above settings, unnecessary communication signal strength acquisition and related analysis actions can be avoided due to the broadcast form of BLE technology and the presence of other smart rings in the use environment, so as to speed up the device response rate.

[0085] In one embodiment of the method, the local side is optimized and configured, which also includes: the physiological indicator data is locally stored and used as a database of a preset generative AI; wherein the generative AI may be a Kimi type.

[0086] According to the above settings, users' personal health data no longer needs to be uploaded to the cloud platform but is stored locally; at the same time, because of the implantation of generative AI, even if the data is not uploaded to the cloud, users can still get health advice through this method.

[0087] In one embodiment of the method, the local side optimizes the configuration, which further includes:

[0088] If the user's interactive behavior meets the preset health information review conditions, the user's current latest behavior scenario is obtained;

[0089] Estimate the user's search items based on the behavior scenario and the user's historical behavior data; for example, the current behavior scenario is running, and the user's historical behavior data shows that the user searches for heart health in this scenario above a threshold (e.g., 80%), then it is estimated that the user will search for heart health.

[0090] According to the preset time consumption for analyzing the user's query items (i.e., the pre-recorded time consumption for initiating a request to receive the monitoring signal and then analyzing the heart rate), the database is searched to obtain matching advertisements to be delivered and delivered before the user checks their health information (i.e., as an advertisement when entering the App); wherein the database records the display time of the advertisements prepared in advance as advertisements when entering the App and the relationship data with the time consumption for analyzing the user's query items.

[0091] It is understandable that this method needs to be implemented through a corresponding program, that is, App implementation, and currently many Apps will choose to place advertisements upon entry; however, the current placement of such advertisements is relatively rigid; this method selects to build a database for advertisements that have placement needs, records their time or divides them into advertisements of different lengths, and then, based on the analysis of the user's current behavior scenarios and behavior habits, selectively selects advertisements of different lengths for placement, so that users do not need to wait when checking certain information, that is, the original waiting time and advertising time can overlap, reducing the user's time occupation.

[0092] The above-mentioned preset health information viewing conditions, for example: the user clicks the corresponding App icon.

[0093] The embodiment of the present application also discloses a monitoring system for a smart ring based on PPG physiological indicator monitoring.

[0094] Reference Figure 3 The monitoring system for a smart ring based on PPG physiological index monitoring includes a smart ring and a personal terminal, and a wireless communication relationship is established between the smart ring and the personal terminal.

[0095] Among them, the personal terminal configuration is:

[0096] Receive the original data uploaded by the smart ring;

[0097] The raw data is processed based on the preset PPG algorithm to obtain physiological index data;

[0098] Perform health assessment based on physiological indicator data to obtain assessment data;

[0099] If the evaluation data meets the preset suspected abnormal conditions, the original data upload conditions are adjusted based on the preset condition adjustment rules, and the new data upload conditions are sent to the smart ring.

[0100] Smart ring configuration is:

[0101] If a new data upload condition is received, the data sent by the personal terminal is parsed using a preset parsing method to obtain a signal characteristic condition and / or an inherent attribute characteristic condition corresponding to the data upload condition;

[0102] If the monitoring signal meets the signal characteristic condition and / or the fixed attribute characteristic condition, the monitoring signal is sent to the personal terminal; wherein the monitoring signal is generated after the sensing unit senses the user's finger.

[0103] Furthermore, the personal terminal is also configured as follows:

[0104] If the user's interactive behavior meets the preset health information review conditions, the user's current latest behavior scenario is obtained;

[0105] Estimate user search items based on behavior scenarios and user historical behavior data;

[0106] According to the preset time consumption of analyzing the user's query items, the database is searched to obtain the matching advertisements to be delivered and delivered before the user checks the health information; wherein, the database records the display time of the advertisements prepared in advance for the App to be entered and the relationship data with the time consumption of analyzing the user's query items.

[0107] The configuration of the personal terminal and the smart ring has been explained in the embodiment of the above method, so it will not be repeated in this embodiment.

[0108] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
