[0035] like Figure 1-5 As shown, this embodiment proposes a smart ring, including: an upper ring shell 1, an electronic component 2, a lower ring shell 3, a ring band 4, thermal conductive silicone 5 and a locking screw 6.

Battery installation slots 302 and piezoelectric sensor installation slots 303 are designed on both sides of the interior; the battery installation slot 302 is used to match and install the battery, and the piezoelectric sensor installation slot 303 is used to install the piezoelectric sensor 203. If the function design is simplified, the blood pressure detection function may be removed, and the piezoelectric sensor installation slot 303 can be selected to place a second battery to improve the endurance of the smart ring. An open rectangular groove 304 is designed at the bottom of the lower shell 3 of the finger ring to position and install the photoelectric sensor 204 fixed on the main control circuit board 202. A thin acrylic plate 305 is placed under the photoelectric sensor 204 and fixed with waterproof glue to achieve sensor protection and waterproof requirements, while meeting the photoelectric sensor 204 to collect finger capillary signals.

The antenna module 2021 uses a patch ceramic antenna to realize the use of a small-sized antenna under the premise of meeting the Bluetooth signal. The main control module 2022 uses a Bluetooth main control chip as the system MCU, and is arranged with circuits such as a main control chip power filter, an RTC battery filter, an RTC clock crystal oscillator, a system clock and a Bluetooth radio frequency antenna to form a main control system circuit to realize the overall control and Bluetooth communication functions. The battery voltage detection module 2023 uses an ADC sampling method to detect the battery voltage, and calculates the battery power through a line graph of the voltage and the battery remaining capacity. At the same time, a sampling circuit control part is arranged to reduce the power loss when not sampling, and meet the low power requirements of the battery voltage detection module 2023. A rechargeable lithium battery 201 is used for power supply, and the power supply module 2024 provides battery protection functions such as reverse current protection, overvoltage protection and surge voltage protection.

[0042] like Figure 1-4 As shown, as a preferred embodiment, on the basis of the above method, further, the battery is connected to the power interface on the circuit board through a flat cable to realize the power supply of the circuit board. After the photoelectric sensor 204 module and the piezoelectric sensor 203 collect the original data, they interact with the main control module 2022 (Bluetooth main control chip) through the I2C digital communication interface. The photoelectric sensor 204 module collects relevant data such as blood oxygen heart rate in real time through the photoelectric chip, and the main control module 2022 selects the Bluetooth main control chip for calculation and analysis, and only transmits the calculation results of heart rate and blood oxygen to the mobile phone terminal, and further data comprehensive processing (including motion analysis, sleep analysis, etc.) and visualization can be performed based on the mobile phone terminal. After the piezoelectric sensor 203 collects the piezoelectric signal of the human pulse, the signal is transmitted to the circuit board through the flat cable, and then transmitted to the mobile phone through Bluetooth. The mobile phone processor adopts the deep learning model fitting calculation of the convolutional neural network long short-term memory (CNNLSTM), which can obtain the blood pressure data of the human body more accurately.

[0043] like Figure 5As shown, as a preferred implementation, on the basis of the above-mentioned method, further, in order to solve the problems of small device size, limited battery space and improving the endurance of the device, a low-power design is performed as a whole.

[0044] The utility model adopts three methods in parallel: distributed edge-terminal collaborative computing, intermittent power supply, and low-power Bluetooth to achieve the reduction of hardware power consumption. The specific contents are as follows: Since the Bluetooth main control chip of the main control module 2022 has limited computing power and blood pressure measurement involves complex algorithms, the utility model uses a distributed edge-terminal collaborative computing system to process physiological parameter data. The original pulse wave signal data measured by the piezoelectric sensor 203 is uploaded to the mobile phone via Bluetooth, and the mobile phone is used to load complex algorithms and calculate blood pressure in combination with the original data. The blood oxygen, heart rate and other data measured by the photoelectric sensor 204 module are directly calculated using the Bluetooth main control chip of the local edge main control module 2022, and only the calculation results are sent to the mobile phone.

[0045] The utility model provides a smart ring, which uses intermittent power supply to reduce system power consumption. The specific method is that when the Bluetooth main control chip of the main control module 2022 calculates data or collects data, the system operation frequency is increased and the relevant sensors are turned on. When the Bluetooth main control chip completes the data calculation or data collection, all sensors are immediately turned off and the MCU operation frequency is reduced to achieve the purpose of reducing power consumption. At the same time, the low-power Bluetooth of BLE technology is used to reduce the comprehensive power consumption of the Bluetooth communication process.

Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods.
