[0001] The present invention relates to the technical field of electronic equipment calibration, and in particular to a calibration system and a calibration method. Background Art

[0002] With the development of technology, wearable devices such as smart bracelets and smart watches have become commonly used electronic devices. The functions of smart bracelets, smart watches and other devices are becoming more and more abundant, usually including the function of detecting physiological parameters such as blood pressure of users. In actual use, the sensor needs to be pressure calibrated regularly to meet the needs of the device to measure the absolute pressure of the skin. Summary of the invention

[0003] The purpose of the present application is to provide a calibration system and a calibration method for calibrating sensors of electronic devices.

[0004] The present application provides a calibration system, the calibration system comprising:

[0005] An electronic device, comprising a main body and a wearing part connected to each other, wherein the wearing part is provided with at least one first sensor;

[0006] A calibration device, the calibration device comprising a main body and at least one second sensor, the second sensor being disposed on the main body;

[0007] Among them, the electronic device can be sleeved on the main body and communicated with the calibration device, the first sensor is located on the side of the wearing part facing the main body, and the second sensor is located on the side of the main body facing the electronic device, and the first sensor and the second sensor are used to detect the pressure between the electronic device and the calibration device.

[0008] The electronic device is communicatively connected to the calibration device so that the electronic device can obtain data from the first sensor and the second sensor. By comparing the detection results of the first sensor and the second sensor, the first sensor is adjusted and calibrated, thereby improving the accuracy of the electronic device for physiological parameters and better meeting actual usage needs.

[0009] In a possible implementation, the calibration device includes at least three second sensors, and the second sensors are arranged at intervals along the circumference of the main body.

[0010] When the electronic device is mounted on the main body, the second sensor can be used to contact different positions of the electronic device, thereby facilitating improving the accuracy of the second sensor in detecting pressure between the electronic device and the calibration device, and being more in line with actual usage requirements.

[0011] In a possible implementation, the calibration device includes at least six second sensors, and at least two of the second sensors are spaced apart along the axial direction of the main body.

[0012] With such a design, the pressure in the same area can be detected by multiple second sensors, which is beneficial to improve the accuracy of the detection results and better meet actual usage requirements.

[0013] In a possible implementation, when the electronic device is sleeved on the main body, the first sensor and the second sensor are spaced apart along the circumference of the main body.

[0014] With such a design, the pressure at different positions can be detected by the first sensor and the second sensor respectively. Usually, when the electronic device detects blood pressure, the pressure at each position is the same or approximately the same. Therefore, the first sensor can be calibrated by the result of the second sensor, thereby improving the accuracy of the detection result of the electronic device.

[0015] In a possible implementation, the first sensor includes a pressure capacitance sensor and a pressure resistance sensor, and the second sensor includes a micro-electromechanical system sensor.

[0016] The pressure capacitance sensor is less affected by environmental factors such as temperature and has good stability, so the detection results are relatively accurate. In addition, the structure is relatively simple and the size is small, making it more suitable for electronic devices such as smart bracelets and smart watches. In addition, the pressure capacitance sensor has good flexibility and is easier to fit with the wrist and other places, which is conducive to improving the detection accuracy. The pressure resistance sensor has high sensitivity and small size, which is more in line with actual use needs. MEMS sensors are characterized by miniaturization, integration, low cost, high efficiency and easy production. MEMS sensors can not only sense the measured parameters and convert them into signals that are easy to measure, but also analyze, process, identify and judge the acquired signals, which is more in line with actual use needs.

[0017] In a possible implementation manner, the wearing portion includes an airbag. The electronic device includes an inflator, and the inflator is used to inflate the airbag.

[0018] By providing an airbag and an inflating device, pressurization can be performed to improve the measurement accuracy. At the same time, the electronic device can be made to fit the object to be detected more closely during use, thereby improving the detection accuracy.

[0019] In a possible implementation, one of the electronic device and the calibration device is provided with a magnetic component, and the other is provided with a matching component. When the electronic device is sleeved on the main body, the magnetic component is connected to the matching component by magnetic attraction.

[0020] By providing magnetic parts and matching parts, the stability of the connection between the electronic device and the calibration device can be improved by magnetic adsorption, thereby reducing the possibility of relative displacement between the electronic device and the calibration device during the calibration process, and further reducing the influence of the relative displacement between the electronic device and the calibration device on the detection results of the first sensor and the second sensor, which is beneficial to improve the calibration accuracy and better meet actual usage needs.

[0021] In a possible implementation, the magnetic component is a neodymium iron boron magnet.

[0022] NdFeB magnets have the advantages of high magnetic properties, high cost performance, and strong machinability. They can be processed into suitable shapes according to actual needs, so that the magnetic parts can better fit electronic equipment and / or calibration equipment, and better meet actual usage needs.

[0023] In a possible implementation, the calibration device includes a base and a connecting portion, the main body is connected to the base via the connecting portion, and an angle is formed between the main body and the connecting portion.

[0024] This design makes it easier to put the electronic device on the main body, reducing the influence of gravity on the electronic device and the possibility of it slipping off the main body. It is more conducive to simulating the state of the user wearing the electronic device on the wrist, which is more in line with actual usage needs.

[0025] In a possible implementation, the calibration device includes a charging coil, which is disposed on the main body and is used to charge the electronic device.

[0026] This design enables the calibration device to have a charging function, and calibration and charging can be performed at the same time, which is helpful to save time. Since the charging process and the calibration process can be performed at the same time, the first sensor of the electronic device can be calibrated regularly by charging, which is helpful to improve the accuracy of the electronic device detection and better meet the actual use needs.

[0027] The present application also provides a calibration method, which is applied to the calibration system described in any one of the above items, and the calibration method includes:

[0028] Sleeving the electronic device on the main body of the calibration device;

[0029] The electronic device sends a calibration instruction to the calibration device;

[0030] The first sensor and the second sensor detect pressure between the electronic device and the calibration device;

[0031] The first sensor is calibrated based on the results of the second sensor.

[0032] The electronic device is mounted on the main body, and a calibration instruction is sent to the calibration device. The first sensor and the second sensor respectively detect the pressure between the electronic device and the calibration device and output the results. The output result can be a pressure value or a reading used to represent the pressure. The electronic device converts the detection result into a pressure value through an internal program or algorithm to calibrate the first sensor.

[0033] In a possible implementation, the electronic device includes an inflatable device, the wearing portion includes an air bag, and before the first sensor and the second sensor detect the pressure between the electronic device and the calibration device, the calibration method includes:

[0034] The inflator inflates the airbag.

[0035] The airbag can be pressurized and help the wearing part of the electronic device to better fit the user, thereby helping to improve the accuracy of detection.

[0036] In a possible implementation, the step of the first sensor and the second sensor detecting the pressure between the electronic device and the calibration device includes:

[0037] 12 to 24 air pressure values ​​in the range of 0 to 40 kPa are recorded and sent to the electronic device.

[0038] In this way, the test results are detected and converted into blood pressure values ​​under standard atmospheric pressure through the internal programs and algorithms of the electronic equipment.

[0039] In a possible implementation, after recording 12 to 24 air pressure values ​​in the range of 0 to 40 kPa and sending them to the electronic device, the calibration method includes:

[0040] The electronic device stores the calibration pressure value and the corresponding data of the first sensor as a calibration data packet, and sends it to the terminal device.

[0041] By sending the calibration data packet to the terminal device, the user can obtain and record the detailed calibration data, thereby facilitating the user to understand the calibration status and calibrate the electronic equipment regularly.

[0042] In a possible implementation, the calibration device includes a charging coil, and the step of sleeve-connecting the electronic device to the main body of the calibration device includes:

[0043] The charging coil is activated and the electronic device starts charging.

[0044] In a possible implementation manner, after calibrating the first sensor according to the result of the second sensor, the calibration method includes:

[0045] Wait for the electronic device to be fully charged and end charging.

[0046] Such a design enables the electronic device to be charged while being calibrated, which helps to save time and facilitates regular calibration of the electronic device, which is more in line with actual usage needs.

[0066] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but should not be construed as limiting the present invention.

[0067] Wearable devices such as smart watches and smart bracelets have become commonly used electronic devices. With the development of technology, the functions of electronic devices such as smart watches and smart bracelets are becoming more and more abundant, and they can usually include the function of measuring physiological parameters such as blood pressure. In conventional medical diagnosis, it is usually necessary to use an inflatable cuff and use a mechanical sensor (such as a stethoscope) to listen to the sound generated by the blood flow vortex in the blood vessels. Blood pressure fluctuates between the maximum pressure (also called systolic pressure) and the minimum pressure (also called diastolic pressure) in each heartbeat cycle. The traditional non-invasive method of measuring blood pressure is to use a pressurized cuff and detect the pressure level when the cuff pressure starts to pulsate between the systolic pressure and the diastolic pressure (that is, the blood starts to flow), and the pressure level when the cuff pressure exceeds the systolic pressure (that is, the blood stops flowing). However, white coat syndrome will increase blood pressure when measuring blood pressure, resulting in inaccurate test results. Therefore, the use of electronic devices such as smart watches and smart bracelets allows users to perform blood pressure tests by themselves, which can effectively reduce the impact of white coat syndrome on test results. Usually, electronic devices measure the user's blood pressure by detecting the pulse wave of the radial artery or ulnar artery of the human body and modeling and predicting it. Compared with the barometer used in the cuff-type blood pressure monitor at the far end of the skin, the pulse wave detection uses a contact pressure sensor that directly contacts the skin. Since the pressure loss and hysteresis caused by the cuff and airbag are eliminated, the detection of intravascular pressure is more direct and accurate. However, in order to improve the accuracy of the test results, it is usually necessary to calibrate the sensor regularly to meet the measurement requirements.

[0068] In view of this, an embodiment of the present application provides a calibration system and a calibration method for calibrating a sensor of an electronic device to improve the accuracy of a detection result.

[0069] like Figure 1 As shown, an embodiment of the present application provides a calibration system, which includes an electronic device 1 and a calibration device 2. The electronic device 1 can be a wearable device such as a smart watch or a smart bracelet, or can be other devices that can be used to detect physiological parameters. The calibration device 2 is used to calibrate the sensor of the electronic device 1.

[0070] like Figure 2 As shown, the electronic device 1 includes a main body 1 and a wearing part 12, the main body 1 and the wearing part 12 are connected to each other, and the wearing part 12 is provided with at least one first sensor 121. Figure 3As shown, the calibration device 2 includes a main body 21 and at least one second sensor 22, and the second sensor 22 is arranged on the main body 21. The electronic device 1 can be sleeved on the main body 21 and communicated with the calibration device 2. The communication connection can use wireless signals such as Bluetooth and WiFi, or a wired method. The first sensor 121 is located on the side of the wearing part 12 facing the main body 21 and is in contact with the main body 21. The second sensor 22 is located on the side of the main body 21 facing the electronic device 1 and is in contact with the electronic device 1. The first sensor 121 and the second sensor 22 are used to detect the pressure between the electronic device 1 and the calibration device 2.

[0071] The electronic device 1 is communicatively connected with the calibration device 2 so that the electronic device 1 can obtain data from the first sensor 121 and the second sensor 22. According to the detection results of the first sensor 121 and the second sensor 22, the first sensor 121 is adjusted and calibrated, thereby improving the accuracy of the electronic device 1 for physiological parameters and better meeting actual usage requirements.

[0072] The calibration system provided in the embodiment of the present application can perform in vitro calibration on the electronic device 1, thereby reducing the discomfort caused to the user by the calibration device 2. Moreover, the first sensor can be calibrated without disassembling the electronic device, which is more in line with actual usage requirements.

[0073] like Figure 4 As shown, in a possible implementation, the calibration device 2 includes at least three second sensors 22 , and the second sensors 22 are arranged at intervals along the circumference of the main body 21 .

[0074] When the electronic device 1 is mounted on the main body 21, the second sensor 22 can be used to contact different positions of the electronic device 1, thereby facilitating improving the accuracy of the second sensor 22 in pressure detection between the electronic device 1 and the calibration device 2, and better meeting actual usage requirements.

[0075] like Figure 2 As shown, taking the electronic device 1 as a smart watch as an example, the main body 1 is the main watch body, and the wearing part 12 is the watch strap. When the electronic device 1 is sleeved on the main body 21, the three second sensors 22 can be respectively located on the opposite sides of the main watch body and the end of the wearing part 12 away from the main watch body. Such a design can make the second sensor 22 contact the electronic device 1 at different positions, so as to be more conducive to simulating the contact of the electronic device 1 with the wrist when it is in the wearing state, so that the pressure at different positions can be detected, and the first sensor 121 can be calibrated according to the detection results to make the pressure at each position the same or close to the same. The main body 21 can be a phantom, used to simulate the skin tissue at the human wrist, so as to simulate the wearing state of the electronic device during the calibration process.

[0076] In a possible implementation, the calibration device 2 includes at least six second sensors 22, such as Figure 3 As shown, at least two second sensors 22 are arranged at intervals along the axial direction of the body portion 21. That is, at least two second sensors 22 are arranged side by side.

[0077] With such a design, the pressure in the same area can be detected by multiple second sensors 22, which is beneficial to improve the accuracy of the detection result and better meet the actual use requirements.

[0078] like Figure 1 As shown, in a possible implementation, when the electronic device 1 is sleeved on the main body 21 , the first sensor 121 and the second sensor 22 are arranged at intervals along the circumference of the main body 21 .

[0079] With such a design, the pressure at different positions can be detected by the first sensor 121 and the second sensor 22 respectively. Usually, when the electronic device 1 detects blood pressure, the pressure at each position is the same or approximately the same. Therefore, the first sensor 121 can be calibrated by the result of the second sensor 22, thereby improving the accuracy of the detection result of the electronic device 1.

[0080] In a possible implementation, the first sensor 121 includes a pressure capacitance sensor and a pressure resistance sensor, and the second sensor 22 is a micro-electro mechanical systems (MEMS) sensor.

[0081] The pressure capacitance sensor is less affected by environmental factors such as temperature and has good stability, so the detection results are relatively accurate. In addition, the structure is relatively simple and the size is small, making it more suitable for electronic devices such as smart bracelets and smart watches. 1 In addition, the pressure capacitance sensor is more flexible and easier to fit with the wrist, which is conducive to improving the detection accuracy. Figure 5 As shown, the first sensor 121 can be an array sensor with multiple channels to improve the detection sensitivity. The pressure resistance sensor has a high sensitivity and a small size, which is more in line with the actual use requirements. The MEMS sensor has the characteristics of miniaturization, integration, low cost, high efficiency and easy production. Moreover, the MEMS sensor can not only sense the measured parameters and convert them into signals that are easy to measure, but also analyze, process, identify and judge the acquired signals, which is more in line with the actual use requirements.

[0082] When in use, the pressure value between the electronic device 1 and the calibration device 2 can be output by the second sensor 22, and the first sensor 121 outputs the corresponding reading, thereby obtaining the relationship between the reading of the first sensor 121 and the pressure value between the electronic device 1 and the calibration device 2, thereby calibrating the first sensor 121 to improve robustness.

[0083] like Figure 6 and Figure 7 As shown, in a possible implementation, the wearing portion 12 includes an airbag 122, and the electronic device 1 includes an inflating device, which is used to inflate the airbag 122. The second sensor 22 contacts the airbag 122, and the first sensor 121 contacts the body portion 21 of the calibration device 2.

[0084] By providing the airbag 122 and the inflation device, pressurization can be performed to improve the measurement accuracy. At the same time, the electronic device 1 can be more closely fitted to the object to be detected during use, thereby facilitating the improvement of detection accuracy.

[0085] like Figure 1 As shown, in a possible implementation, one of the electronic device 1 and the calibration device 2 has a magnetic component 13, and the other has a matching component 23. When the electronic device 1 is sleeved on the main body 21, the magnetic component 13 is magnetically connected to the matching component 23. The matching component 23 can be a component with magnetism, or a component that can be attracted by the magnetic component 13.

[0086] By providing the magnetic part 13 and the matching part 23, the stability of the connection between the electronic device 1 and the calibration device 2 can be improved by magnetic adsorption, thereby reducing the possibility of relative displacement between the electronic device 1 and the calibration device 2 during the calibration process, and further reducing the influence of the relative displacement between the electronic device 1 and the calibration device 2 on the detection results of the first sensor 121 and the second sensor 22, which is beneficial to improve the calibration accuracy and better meet the actual usage requirements.

[0087] In a possible implementation, both the magnetic component 13 and the matching component 23 may be neodymium iron boron magnets.

[0088] Neodymium iron boron magnets have the advantages of high magnetic properties and high cost performance, and they are easy to machine and can be processed into suitable shapes according to actual needs, so that the magnetic part 13 can better fit the electronic device 1 and / or calibration device 2, and better meet actual usage needs.

[0089] like Figure 8As shown, in a possible implementation, the calibration device 2 includes a base 25 and a connecting portion 24, the connecting portion 24 is used to connect the main body 21 and the base 25, and there is an angle between the main body 21 and the connecting portion 24. The cross-section of the main body 21 can be circular, elliptical, etc., so as to imitate the structure of the wrist, and the axial direction of the main body 21 can be perpendicular to the connecting portion 24. When the calibration device 2 is placed on a desktop or the like, the axial direction of the main body 21 can extend in the horizontal direction, or be approximately parallel to the horizontal direction.

[0090] This design makes it easier to put the electronic device 1 on the main body 21, reducing the influence of gravity on the electronic device 1 and the possibility of it sliding off the main body 21. It is more conducive to simulating the state of the user wearing the electronic device 1 on the wrist, which is more in line with actual usage needs.

[0091] In a possible implementation, the calibration device 2 may further include a charging coil, which is disposed on the main body 21 , so that the calibration device 2 can charge the electronic device 1 through the charging coil.

[0092] This design enables the calibration device 2 to have a charging function, and can perform calibration and charging at the same time, which is helpful to save time. Since the charging process and the calibration process can be performed at the same time, the first sensor 121 of the electronic device 1 can be regularly calibrated by charging, which is helpful to improve the accuracy of the detection of the electronic device 1 and better meet the actual use requirements.

[0093] In a possible implementation, the calibration device 2 can be integrated into scenarios such as a wireless charging device, a smart speaker, a smart home control terminal, or other locations where the electronic device 1 can be placed, so as to calibrate the first sensor 121 of the electronic device 1 during the idle period of the electronic device 1, which is more in line with actual usage needs.

[0094] Based on the calibration systems involved in the above embodiments, an embodiment of the present application further provides a calibration method, which can be used for the calibration system involved in any of the above embodiments.

[0095] like Fig. 9 As shown, in a possible implementation, the calibration method includes:

[0096] S1. Put the electronic device 1 on the main body 21 of the calibration device 2.

[0097] S2. The electronic device 1 sends a calibration instruction to the calibration device 2.

[0098] S3 , the first sensor 121 and the second sensor 22 detect the pressure between the electronic device 1 and the calibration device 2 .

[0099] S4. Calibrate the first sensor 121 according to the result of the second sensor 22.

[0100] The electronic device 1 is mounted on the main body 21, and a calibration instruction is sent to the calibration device 2. The first sensor 121 and the second sensor 22 respectively detect the pressure between the electronic device 1 and the calibration device 2 and output the results. The output result can be a pressure value or a reading used to represent the pressure. The electronic device 1 converts the detection result into a pressure value through an internal program or algorithm to calibrate the first sensor 121.

[0101] like Fig. 9 As shown, in a possible implementation, the electronic device 1 includes an inflatable device, the wearing portion 12 includes an airbag 122, and before performing step S3, the calibration method includes:

[0102] S21 , the inflating device inflates the airbag 122 .

[0103] The airbag 122 can be pressurized, and the wearing portion 12 of the electronic device 1 can better fit the user, thereby facilitating improved detection accuracy.

[0104] like Fig. 9 As shown, in a possible implementation manner, step S3 further includes:

[0105] S31 . Record 12 to 24 air pressure values ​​in the range of 0 to 40 kPa and send them to the electronic device 1 .

[0106] The test results are recorded in this way, and converted into blood pressure values ​​under standard atmospheric pressure through the internal program and algorithm of the electronic device 1.

[0107] like Fig. 9 As shown, in a possible implementation manner, after step S31, the calibration method further includes:

[0108] S32. The electronic device 1 stores the calibration pressure value and the corresponding data of the first sensor 121 as a calibration data packet, and sends it to the terminal device.

[0109] Usually, wearable devices such as smart watches and smart bracelets are connected to terminal devices such as mobile phones, tablets, and laptops. By sending calibration data packets to the terminal devices, users can obtain detailed calibration data and record them, thereby facilitating understanding of the calibration status and regularly calibrating the electronic device 1.

[0110] like Fig.10As shown, in a possible implementation, the second sensor 22 outputs the pressure value between the electronic device 1 and the calibration device 2, and the average value of the pressure values ​​of each second sensor 22 is calculated, and the average value can be used as the calibration pressure of the first sensor 121. Each first sensor 121 may include multiple sensing units, such as Fig.11 As shown, each sensing unit is used to output a reading representing the pressure between the electronic device 1 and the calibration device 2, obtain the relationship between the calibration pressure and the reading, and calibrate the first sensor 121.

[0111] It should be noted here that Fig.10 and Fig.11 The data involved are obtained from experiments and are only used to discuss the solutions provided in the embodiments of the present application, and do not represent data in actual use.

[0112] like Fig. 9 As shown, in a possible implementation, step S1 includes:

[0113] S11 , activating the charging coil, and the electronic device 1 starts charging.

[0114] like Fig. 9 As shown, in a possible implementation manner, after step S4, the calibration method includes:

[0115] S5, waiting for the electronic device 1 to be fully charged and ending the charging.

[0116] With such a design, the electronic device 1 can be charged while being calibrated, which is helpful to save time and facilitates regular calibration of the electronic device 1, which is more in line with actual usage requirements.

[0117] like Fig.12 As shown, in a possible implementation, the control interface of the electronic device 1 may include calibration information, calibration remaining time, and power, etc. The user can manually start or stop the calibration, and know whether the calibration is completed through the calibration remaining time. The control interface of the electronic device 1 is relatively simple, which can reduce the user's learning cost and facilitate use, which is conducive to increasing user stickiness. After the calibration is completed, Fig.13As shown, the electronic device 1 can draw a linearity diagram of the first sensor 121, wherein the horizontal axis is the calibration pressure and the vertical axis is the sensing pressure. The electronic device 1 uses a built-in program or algorithm to calculate and quantify the health of the first sensor 121. When the health of the first sensor 121 drops to a certain level, the electronic device 1 can issue a prompt to the user to replace the first sensor 121 or replace the wearing part 12 with the first sensor 121 in time. When the electronic device 1 includes multiple first sensors 121, the electronic device 1 can number each first sensor 121 and draw a linearity diagram of each first sensor 121 respectively. The user can obtain the health of each first sensor 121 and replace the corresponding first sensor 121.

[0118] In a possible implementation, the health of the first sensor 121 can be quantified as 0 to 100. A preset value is set according to the accuracy of the first sensor 121. Taking the preset value of 60 as an example, when the health of the first sensor 121 is not less than 60, the electronic device 1 can be used normally. When the health of the first sensor 121 is less than 60, the electronic device 1 prompts the user to replace the first sensor 121 and gives the number corresponding to the first sensor 121 for easy maintenance.

[0119] like Fig.14 As shown, in a possible implementation, the second sensor 22 is a micro-electromechanical system sensor, and the multi-channel pressure signals output by the second sensor 22 are collected by a multiplexer (multiplexe, MUX), amplified by one or more voltage amplifiers, and then sampled as digital signals by an analog-to-digital converter (analog-to-digital converter, ADC) and transmitted to the microcontroller unit (microcontroller unit, MCU) of the calibration device 2, and then can be transmitted to terminals such as mobile phones, tablet computers, and laptops through communication methods such as Bluetooth.

[0120] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings.
