[0002] In the prior art, for example, when the weighing electronic equipment, the physical measurement equipment, the human body composition analyzer or the body fat scale and the like electronic equipment is in the process of weighing, the weight value is acquired through at least one pressure sensor arranged on the electronic equipment, and the weight zero point of the electronic equipment corresponds to the weight value of the signal output of the pressure sensor under the condition that no external weight is applied. The weight zero point is crucial to the accuracy of subsequent weight measurement values. In the prior art, after the electronic equipment is powered on, a preset time period is required, and then the weight zero point is acquired as calibration data according to the signals collected by the pressure sensor during the preset time period. The above-mentioned method requires the user to wait for a preset time period, and if the user does not place the electronic equipment on a flat surface in time after the electronic equipment is powered on, the error caused by the self-weight of the electronic equipment cannot be eliminated, which is not conducive to quickly and accurately acquiring calibration data, and the user experience is poor.

The use of the words "example" or "for example" is intended to present relative concepts in a clear manner.

[0050] It should be noted that in the embodiments of this application, "and / or" describes the relationship between associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. In addition, the character " / ", unless otherwise specified, generally indicates that the associated objects before and after it are in an "or" relationship.

[0051] It should be noted that in the embodiments of this application, "connection" can be understood as electrical connection. The connection between two electrical components can be a direct or indirect connection between the two electrical components. For example, the connection between A and B can be a direct connection between A and B, or an indirect connection between A and B through one or more other electrical components.

[0052] The calibration and measurement device 100 provided in this application can be applied to, for example... Figure 1The illustrated electronic device 200 includes a pressure sensor 101 connected to a calibration measuring device 100. The calibration measuring device 100 performs a calibration process based on the electrical signal output by the pressure sensor 101 and outputs calibration measurement data characterizing the zero weight point based on the result of the calibration process. Optionally, the electronic device 200 can be a weighing electronic device, a vital signs measuring device, a body composition analyzer, or a body fat scale, etc., such as a body scale.

[0053] One embodiment of this application provides a calibration measurement device 100. Please refer to [link to relevant documentation]. Figure 2 As shown, the calibration measurement device 100 is applied to an electronic device equipped with a pressure sensing device 101. The calibration measurement device 100 includes a signal processing module 11 and a microprocessor 12.

[0054] In this embodiment, during the operation of the electronic device, the pressure sensing device 101 outputs an electrical signal at preset intervals, with each sampling time corresponding to an electrical signal. This electrical signal is used to characterize the pressure sensed by the pressure sensing device 101.

[0055] The signal processing module 11 is used to receive the electrical signal generated by the pressure sensing device 101 and output the processing signal corresponding to the electrical signal.

[0056] In one implementation, the signal processing module 11 performs signal conditioning on the received electrical signal (generally an analog signal) to obtain a digital signal corresponding to the electrical signal, and outputs the obtained digital signal as a processed signal. In this implementation, signal conditioning may include one or more signal conditioning methods such as signal amplification, signal filtering, and signal isolation, in addition to analog-to-digital conversion.

[0057] The microprocessor 12 is used to perform the following steps: after detecting that the electronic device is turned on, it enters the calibration process and detects whether the user has performed a calibration measurement operation according to the first processing signal output by the signal processing module 11; after detecting that the user has performed a calibration measurement operation, it detects whether the electronic device meets the calibration measurement conditions according to the second processing signal output by the signal processing module 11; when the electronic device meets the calibration measurement conditions, it acquires the calibration measurement data according to the second processing signal and ends the calibration process.

[0058] In this embodiment, after the electronic device is turned on, the microprocessor 12 enters the calibration process. When the microprocessor 12 detects that the electronic device is powered on, it determines that the electronic device is turned on and then enters the calibration process. The first processing signal is generated by the signal processing module 11 based on the electrical signal output to it by the pressure sensing device 101 after entering the calibration process. The microprocessor 12 detects whether the user has performed a calibration measurement operation based on the first processing signal received after entering the calibration process.

[0059] When a user performs a calibration measurement operation, they apply pressure to the electronic device. The pressure sensor 101 generates an electrical signal based on the pressure applied by the user during the calibration measurement operation. The signal processing module 11 outputs a corresponding first processed signal based on the electrical signal generated by the pressure applied by the user during the calibration measurement operation. The microprocessor 12 detects the user's calibration measurement operation based on the first processed signal.

[0060] After detecting that the user has performed a calibration measurement operation, the microprocessor 12 begins to detect whether the electronic device meets the calibration measurement conditions. The second processing signal is generated by the signal processing module 11 based on the electrical signal output to it by the pressure sensing device 101 after the calibration measurement operation is performed. The microprocessor 12 detects whether the electronic device meets the calibration measurement conditions based on the second processing signal received after the calibration measurement operation is performed.

[0061] The calibration measurement device of this embodiment is configured with a calibration processing flow. Once activated, it enters this flow and detects when a user has performed a calibration measurement operation. It then checks whether the electronic device meets the calibration measurement conditions. When the conditions are met, calibration measurement data is acquired based on a second processing signal. Because of the calibration processing flow, the user is not forced to wait for a preset time, which improves the speed of calibration measurement. Furthermore, since the user performs the calibration measurement operation during the processing flow, it avoids data collection when the electronic device is in a suspended or tilted position, effectively reducing calibration measurement errors. The calibration measurement device of this embodiment solves the problem of not being able to quickly and accurately acquire calibration measurement data, improving both the measurement speed and accuracy.

[0062] In some embodiments, the microprocessor 12 is further configured to acquire corresponding first measurement data based on the received first processing signal; if the first measurement data is greater than or equal to a first measurement threshold, it is determined that the user has performed a calibration measurement operation. In this embodiment, the method for detecting whether the user has performed a calibration measurement operation is that when the microprocessor 12 detects a first measurement data that is greater than or equal to the first measurement threshold, it is determined that the user has performed a calibration measurement operation.

[0063] In some embodiments, the microprocessor 12 is further configured to: if the first measurement data is less than the first measurement threshold, determine that the user has not performed a calibration measurement operation, and continue to detect whether the user has performed a calibration measurement operation based on the first processing signal output by the signal processing module 11. In this embodiment, if no first measurement data greater than or equal to the first measurement threshold is detected, it indicates that the user has not currently performed a calibration measurement operation, and the detection of the calibration measurement operation can continue.

[0064] As one implementation method, the calibration measurement operation can be a stepping or pressing operation on the electronic device.

[0065] As one implementation, considering that the force of the calibration measurement operation performed by the user, such as stepping or pressing, is much greater than the weight of the electronic device, the first measurement threshold can be set as a multiple of the weight of the electronic device. For example, it can be set to be greater than or equal to five times, nine times, ten times, etc., the weight of the electronic device.

[0066] In some implementations, the microprocessor 12 is further configured to acquire corresponding second measurement data based on the received second processing signal; if the second measurement data is less than the second measurement threshold, then it is determined that the electronic device meets the calibration measurement conditions.

[0067] In this embodiment, when the electronic device meets the calibration measurement conditions, the pressure sensed by the pressure sensing device 101 is the pressure generated by the weight of the electronic device itself.

[0068] In some embodiments, the microprocessor 12 is further configured to: if the second measurement data is greater than or equal to the second measurement threshold, determine that the electronic device does not meet the calibration measurement conditions, and continue to execute the step of acquiring the corresponding second measurement data according to the received second processing signal. In this embodiment, if the second measurement data is greater than or equal to the second measurement threshold, it is possible to continue detecting whether the electronic device meets the calibration measurement conditions.

[0069] In one implementation, the second measurement threshold is set based on an empirical value of the electronic device's weight. Specifically, the second measurement threshold can be a value slightly larger than the electronic device's weight; for example, the second measurement threshold can be (1+k)*W, where W is the weight of the electronic device and k is 0.005 to 0.1.

[0070] As one implementation method, if the second measurement data is less than the second measurement threshold, that is, if the calibration measurement conditions are met, the current second measurement data can be used as the basis for obtaining calibration measurement data.

[0071] In some embodiments, the microprocessor 12 is further configured to: when the electronic device is detected to meet the calibration measurement conditions, use the second measurement data corresponding to the second processing signal as calibration measurement data and end the calibration process. In this embodiment, when the electronic device meets the calibration measurement conditions, the second measurement data can be considered to correspond to the weight value of the electronic device, so the second measurement data can be directly used as the calibration measurement data.

[0072] In other embodiments, the microprocessor 12 is further configured to: when the electronic device is detected to meet the calibration measurement conditions, acquire calibration measurement data based on the second measurement data corresponding to the second processing signal, and end the calibration process. In this embodiment, in order to obtain more accurate calibration measurement data and avoid measurement deviations between the second measurement data and the actual weight value of the electronic device caused by unstable placement of the electronic device, the second measurement data may not be directly used as calibration measurement data. Instead, the second measurement data may be corrected first, and the corrected second measurement data may be used as calibration measurement data. For example, the second measurement data may be multiplied by a preset correction factor to obtain the corrected second measurement data. The preset correction factor may be determined based on the empirical error between the actual weight value of the electronic device and the measured weight value of the electronic device.

[0073] In some embodiments, the microprocessor 12 is also used to obtain initial calibration data based on the initial processing signal output by the signal processing module 11 when the electronic device is detected to be turned on; wherein the initial processing signal corresponds to the time when the electronic device is turned on.

[0074] In this embodiment, the electronic device is considered to be turned on when it is powered on. The initial electrical signal collected by the pressure sensing device 101 is input to the signal processing module 11. The initial electrical signal is the electrical signal collected by the pressure sensing device 101 at the time when the electronic device is turned on. The signal processing module 11 outputs the initial processing signal. That is, both the initial electrical signal and the initial processing signal correspond to the time when the electronic device is turned on. The time when the electronic device is powered on can be the time when the electronic device is powered on.

[0075] In this embodiment, in order to improve the accuracy of the electronic device measurement, each time the electronic device is powered on, an initial electrical signal corresponding to the power-on time can be collected, an initial processing signal can be obtained based on the initial electrical signal, and then the initial calibration data corresponding to the power-on time of the electronic device can be obtained based on the initial processing signal.

[0076] In other implementations, to save power consumption, the initial calibration data obtained during the first power-on can be reused each time the electronic device is powered on.

[0077] In this embodiment, in addition to acquiring calibration measurement data, it is also necessary to collect initial calibration data upon power-on. This initial calibration data can be used for calibration of subsequent measurement data or for subsequent analysis of the electronic device's state upon power-on. It should be noted that if the electronic device is in a suspended state upon power-on, for example, if the user holds the electronic device without putting it down, initial calibration data cannot be successfully acquired.

[0078] In some embodiments, the microprocessor 12 is further configured to detect whether the electronic device meets the calibration measurement conditions based on the first processing signal output by the signal processing module 11; if the detection result is yes, then the calibration measurement data is obtained based on the first processing signal, and the calibration process ends; if the detection result is no, then the user is detected based on the first processing signal to determine whether the calibration measurement operation has been performed.

[0079] In this embodiment, upon detecting that the electronic device is powered on, it enters the calibration process. The microprocessor 12 receives a first processing signal. Before detecting whether the user has performed a calibration measurement operation based on the first processing signal, the microprocessor 12 can first check whether the calibration measurement conditions are met. If the electronic device meets the calibration measurement conditions, the calibration measurement data is directly obtained based on the first processing signal, and the calibration process exits. If the electronic device does not meet the calibration measurement conditions, the system then checks whether the user has performed a calibration measurement operation. Through this embodiment, the user can immediately place the electronic device on a flat surface after powering it on. Under this premise, the calibration process can detect that the electronic device meets the calibration measurement conditions, and the user does not need to perform a calibration measurement operation. The calibration measurement data can be directly obtained, and the calibration process can then exit. The electronic device can then enter the normal measurement process, improving the efficiency of calibration measurement and enhancing the user experience. This embodiment is applicable to scenarios where the user lifts the electronic device (fully or partially) to power it on, obtains initial calibration data, and then places the electronic device flat.

[0080] In some implementations, the microprocessor 12 detects whether the electronic device meets the calibration measurement conditions based on the first processing signal output by the signal processing module 11. This may include: the microprocessor 12 acquiring corresponding first measurement data based on the received first processing signal; if the first measurement data is less than a second measurement threshold, then determining that the electronic device meets the calibration measurement conditions.

[0081] As one implementation method, if the first measurement data is less than the second measurement threshold, that is, if the calibration measurement conditions are met, the current first measurement data can be used as the basis for obtaining calibration measurement data.

[0082] In some embodiments, the microprocessor 12 is further configured to: when the electronic device is detected to meet the calibration measurement conditions, use the first measurement data corresponding to the first processing signal as calibration measurement data and end the calibration process. In this embodiment, when the electronic device meets the calibration measurement conditions, the first measurement data can be considered to correspond to the weight value of the electronic device, so the second measurement data can be directly used as the correction measurement data.

[0083] In other embodiments, the microprocessor 12 is further configured to: when the electronic device is detected to meet the calibration measurement conditions, acquire calibration measurement data based on the first measurement data corresponding to the first processing signal, and end the calibration process. In this embodiment, in order to obtain more accurate calibration measurement data and avoid measurement deviations between the first measurement data and the actual weight value of the electronic device caused by unstable placement of the electronic device, the first measurement data may not be directly used as calibration measurement data. Instead, the first measurement data may be corrected firstly, and the corrected first measurement data may be used as calibration measurement data. For example, the first measurement data may be multiplied by a preset correction factor to obtain the corrected first measurement data. The preset correction factor may be determined based on the empirical error between the actual weight value of the electronic device and the measured weight value of the electronic device.

[0084] In some implementations, to further avoid false detections of whether an electronic device meets calibration measurement conditions, a third measurement threshold can be set based on the second measurement threshold. The second measurement threshold serves as an upper limit threshold, and the third measurement threshold serves as a lower limit threshold. The third measurement threshold can be set based on empirical values ​​of the electronic device's weight. The microprocessor 12 detects whether the electronic device meets calibration measurement conditions based on the first processing signal output by the signal processing module 11. This can include: the microprocessor 12 acquiring corresponding first measurement data based on the received first processing signal; if the first measurement data is less than the second measurement threshold and greater than or equal to the third measurement threshold, then it is determined that the electronic device meets the calibration measurement conditions. By setting the lower limit threshold in this implementation, if the user holds the electronic device in a suspended or tilted state after powering it on without performing a calibration measurement operation, it will be impossible to detect whether the electronic device meets the calibration measurement conditions, thus avoiding false detections of whether the calibration measurement conditions are met and improving the accuracy of calibration.

[0085] In some implementations, the microprocessor 12 is further configured to determine whether the calibration process has timed out based on the current time and the power-on time of the electronic device; if the calibration process timed out, calibration measurement data is acquired based on the processing signal corresponding to the current time output by the signal processing module, and the calibration process is terminated. Further, acquiring calibration measurement data based on the processing signal corresponding to the current time output by the signal processing module includes: acquiring corresponding measurement data based on the received processing signal corresponding to the current time, and using the acquired measurement data as calibration measurement data.

[0086] In this embodiment, if calibration measurement data cannot be successfully obtained after entering the calibration process, it will lead to excessively long user waiting time, which is detrimental to user experience. This embodiment addresses this with an automatic timeout exit mechanism. A time threshold is set; if the time difference between the current time and the electronic device's power-on time is greater than or equal to this threshold, the calibration process is determined to have timed out. Calibration measurement data is then obtained based on the processing signal corresponding to the current time, and the calibration process ends. This embodiment exits the calibration process after a timeout, avoiding prolonged user waiting and improving user experience. This embodiment is suitable for scenarios where the user holds the electronic device in their hand after powering it on or places the electronic device flat before initial calibration data is obtained.

[0087] In some implementations, please refer to Figure 3 As shown, the electronic device also includes a display module 102, and the microprocessor 12 is also used to send calibration measurement prompt information to the display module 102. The calibration measurement prompt information is used to prompt the user to perform calibration measurement operations.

[0088] In this embodiment, after entering the calibration process, the microprocessor 12 displays calibration measurement prompts to the user through the display module, allowing the user to perform calibration measurement operations based on these prompts. This implementation method improves calibration measurement efficiency.

[0089] In some embodiments, the signal processing module 11 includes a signal conditioning device 111 and an analog-to-digital converter 112. The signal conditioning device 111 is used to receive the electrical signal from the pressure sensing device 101 and output a conditioning signal corresponding to the electrical signal. The analog-to-digital converter 112 is used to receive the conditioning signal output by the signal conditioning device 111, convert the conditioning signal into a corresponding digital signal, and output the digital signal as a processing signal corresponding to the electrical signal.

[0090] In one embodiment, the pressure sensing device 101 in the electronic device may include at least one pressure sensor.

[0091] In this embodiment, the calibration measurement device is configured with a calibration processing flow. After detecting that the user has performed a calibration measurement operation, it then detects whether the electronic device meets the calibration measurement conditions. When the electronic device is detected to meet the calibration measurement conditions, the calibration measurement data is obtained according to the corresponding second processing signal. Since the user has performed a calibration measurement operation, the calibration measurement data can be avoided when the electronic device is not in a flat position, which can solve the problem of low weighing accuracy and improve the weighing accuracy.

[0092] One embodiment of this application provides a calibration measurement method applied to an electronic device equipped with a pressure sensing device and a signal processing module. The signal processing module receives the electrical signal from the pressure sensing device and outputs a processed signal corresponding to the electrical signal. The signal processing module is communicatively connected to a microprocessor. Please refer to [link to relevant documentation]. Figure 4 As shown, the calibration measurement methods include:

[0093] S11, After the microprocessor detects that the electronic device is turned on, it enters the calibration process;

[0094] Once the electronic device is turned on, the microprocessor enters the calibration process.

[0095] S12, the microprocessor detects whether the user has performed a calibration measurement operation based on the first processed signal output by the signal processing module;

[0096] In this process, the microprocessor enters the calibration process. When the microprocessor detects that the electronic device is powered on, it determines that the electronic device is turned on and then enters the calibration process. The first processing signal is generated by the signal processing module based on the electrical signal output to it by the pressure sensing device after entering the calibration process. The microprocessor detects whether the user has performed a calibration measurement operation based on the first processing signal received after entering the calibration process.

[0097] S13, after the microprocessor detects that the user has performed a calibration measurement operation, it detects whether the electronic device meets the calibration measurement conditions based on the second processed signal output by the signal processing module.

[0098] When a user performs a calibration measurement, they apply pressure to the electronic device. A pressure sensor generates an electrical signal based on this pressure, and a signal processing module outputs a corresponding first processed signal based on this signal. The microprocessor then detects the user's calibration measurement operation based on this first processed signal.

[0099] S14, when the electronic device is detected to meet the calibration measurement conditions, the microprocessor obtains the calibration measurement data according to the second processing signal and ends the calibration process;

[0100] After detecting that the user has performed a calibration measurement operation, the microprocessor begins to detect whether the electronic device meets the calibration measurement conditions. The second processing signal is generated by the signal processing module based on the electrical signal output by the pressure sensing device after the calibration measurement operation is performed. The microprocessor detects whether the electronic device meets the calibration measurement conditions based on the second processing signal received after the calibration measurement operation is performed.

[0101] The calibration measurement method of this embodiment is configured with a calibration processing flow. Once activated, this flow is initiated. After detecting that the user has performed a calibration measurement operation, the method checks whether the electronic device meets the calibration measurement conditions. When the conditions are met, calibration measurement data is acquired based on a second processing signal. Because of the configured calibration processing flow, the user is not forced to wait for a preset time, which improves the speed of calibration measurement. Furthermore, since the user performs the calibration measurement operation during the processing flow, the data collection avoids situations where the electronic device is suspended or tilted, effectively reducing calibration measurement errors. This calibration measurement method solves the problem of not being able to quickly and accurately acquire calibration measurement data, improving both the measurement speed and accuracy.

[0102] In one implementation, step S12 involves detecting whether the user has performed a calibration measurement operation based on the first processed signal output by the signal processing module, specifically including the following steps:

[0103] S121, Obtain the corresponding first measurement data according to the received first processing signal;

[0104] S122, if the first measurement data is greater than or equal to the first measurement threshold, it is determined that the user has performed a calibration measurement operation;

[0105] The method for detecting whether a user has performed a calibration measurement operation is as follows: when the microprocessor detects a first measurement data that is greater than or equal to a first measurement threshold, it can be determined that the user has performed a calibration measurement operation.

[0106] In some embodiments, detecting whether the user has performed a calibration measurement operation based on a first processed signal output by the signal processing module further includes the following steps: if the first measurement data is less than a first measurement threshold, it is determined that the user has not performed a calibration measurement operation, and the detection of whether the user has performed a calibration measurement operation continues based on the first processed signal output by the signal processing module. In this embodiment, if no first measurement data greater than or equal to the first measurement threshold is detected, it indicates that the user has not currently performed a calibration measurement operation, and the detection of the calibration measurement operation can continue.

[0107] In some implementations, considering that the force of a user's calibration measurement operation, such as stepping or pressing, is much greater than the weight of the electronic device, the first measurement threshold can be set as a multiple of the weight of the electronic device, for example, it can be set to be greater than or equal to five times, nine times, ten times, etc. of the weight of the electronic device.

[0108] In one implementation, step S13, detecting whether the electronic device meets the calibration measurement conditions based on the second processed signal output by the signal processing module, includes:

[0109] S131, Obtain the corresponding second measurement data according to the received second processing signal;

[0110] S132, if the second measurement data is less than the second measurement threshold, then the electronic device is determined to meet the calibration measurement conditions;

[0111] When the electronic device meets the calibration measurement conditions, the pressure sensed by the pressure sensor is the pressure generated by the weight of the electronic device itself, and the corresponding weight value is generally slightly greater than the weight of the electronic device. In some embodiments, the second measurement threshold is set based on an empirical value of the weight of the electronic device. Specifically, the second measurement threshold can be a value slightly greater than the weight of the electronic device; for example, the second measurement threshold can be (1+k)*W, where W is the weight of the electronic device and k is 0.005 to 0.1.

[0112] In some embodiments, detecting whether the electronic device meets the calibration measurement conditions based on the second processed signal output by the signal processing module further includes the following step: if the second measurement data is greater than or equal to the second measurement threshold, then it is determined that the electronic device does not meet the calibration measurement conditions, and the step of obtaining the corresponding second measurement data based on the received second processed signal continues. In this embodiment, if the second measurement data is greater than or equal to the second measurement threshold, it is permissible to continue detecting whether the electronic device meets the calibration measurement conditions.

[0113] As one implementation method, if the second measurement data is less than the second measurement threshold, that is, if the calibration measurement conditions are met, the second measurement data can be used as the basis for obtaining the calibration measurement data.

[0114] In some embodiments, step S14 specifically includes: when the electronic device is detected to meet the calibration measurement conditions, using the second measurement data corresponding to the second processing signal as the calibration measurement data, and ending the calibration process. In this embodiment, when the electronic device meets the calibration measurement conditions, the second measurement data can be considered to correspond to the weight value of the electronic device, so the second measurement data can be directly used as the calibration measurement data.

[0115] In other embodiments, step S14 specifically includes: when the electronic device is detected to meet the calibration measurement conditions, acquiring calibration measurement data based on the second measurement data corresponding to the second processing signal, and ending the calibration process. In this embodiment, in order to obtain more accurate calibration measurement data and avoid measurement deviations between the second measurement data and the actual weight value of the electronic device caused by unstable placement of the electronic device, the second measurement data may not be directly used as calibration measurement data. Instead, the second measurement data may be corrected first, and the corrected second measurement data may be used as calibration measurement data. For example, the second measurement data may be multiplied by a preset correction coefficient to obtain the corrected second measurement data. The preset correction coefficient may be determined based on the error empirical value between the weight value of the electronic device and the measured weight value of the electronic device.

[0116] In one implementation, the following steps are included before step S11:

[0117] S10, when the electronic device is detected to be powered on, the microprocessor obtains initial calibration data based on the initial processing signal output by the signal processing module; wherein, the initial processing signal corresponds to the power-on time of the electronic device.

[0118] In this embodiment, the moment the electronic device is powered on is considered as the electronic device being turned on. The initial electrical signal collected by the pressure sensing device is input to the signal processing module. The initial electrical signal is the electrical signal collected by the pressure sensing device at the time the electronic device is turned on. The signal processing module outputs an initial processed signal. Both the initial electrical signal and the initial processed signal correspond to the time the electronic device is turned on, which can be the moment the electronic device is powered on. In this embodiment, to improve the accuracy of the electronic device's measurements, the initial electrical signal corresponding to the time of turn-on can be collected each time the electronic device is powered on. The initial processed signal is obtained based on the initial electrical signal, and then the initial calibration data corresponding to the time of turn-on of the electronic device is obtained based on the initial processed signal.

[0119] In other implementations, to save power consumption, the initial calibration data obtained during the first power-on can be reused each time the electronic device is powered on.

[0120] In this embodiment, in addition to acquiring calibration measurement data, it is also necessary to collect initial calibration data upon power-on. This initial calibration data can be used for the calibration of subsequent measurement data or for subsequent analysis of the state of the electronic device upon power-on. It should be noted that if the electronic device is in a suspended, non-flat state upon power-on, for example, if the user holds the electronic device without putting it down, the initial calibration data cannot be successfully acquired.

[0121] In one implementation, after step S11 and before step S12, the following steps are also included:

[0122] S11a, the microprocessor detects whether the electronic device meets the calibration measurement conditions based on the first processed signal output by the signal processing module;

[0123] S11b, If the detection result is yes, then obtain the calibration measurement data according to the first processing signal and end the calibration process;

[0124] S11c, if the detection result is negative, proceed to step S12.

[0125] In this embodiment, after the electronic device is detected to be powered on, the calibration process begins. The microprocessor receives a first processing signal. Before detecting whether the user has performed a calibration measurement operation based on the first processing signal, the microprocessor first checks whether the calibration measurement conditions are met. If the electronic device meets the calibration measurement conditions, the microprocessor directly acquires the calibration measurement data based on the first processing signal and exits the calibration process. If the electronic device does not meet the calibration measurement conditions, the microprocessor then checks whether the user has performed a calibration measurement operation. Through this embodiment, the user can immediately place the electronic device on a flat surface after powering on. Under this premise, the calibration process can detect that the electronic device meets the calibration measurement conditions. The user does not need to perform a calibration measurement operation and can directly acquire the calibration measurement data and then exit the calibration process. The electronic device can then enter the normal measurement process, improving the efficiency of calibration measurement and enhancing the user experience.

[0126] In some embodiments, step S11a, where the microprocessor detects whether the electronic device meets the calibration measurement conditions based on the first processing signal output by the signal processing module, may include: the microprocessor acquiring corresponding first measurement data based on the received first processing signal; if the first measurement data is less than a second measurement threshold, then determining that the electronic device meets the calibration measurement conditions. In some embodiments, the second measurement threshold is set based on an empirical value of the electronic device's weight.

[0127] As one implementation method, if the first measurement data is less than the second measurement threshold, that is, if the calibration measurement conditions are met, the first measurement data can be used as the basis for obtaining the calibration measurement data.

[0128] In some embodiments, step S11b specifically includes: when the electronic device is detected to meet the calibration measurement conditions, using the first measurement data corresponding to the first processing signal as the calibration measurement data, and ending the calibration process. In this embodiment, when the electronic device meets the calibration measurement conditions, the first measurement data can be considered to correspond to the weight value of the electronic device, so the second measurement data can be directly used as the correction measurement data.

[0129] In other embodiments, step S11b specifically includes: when the electronic device is detected to meet the calibration measurement conditions, acquiring calibration measurement data based on the first measurement data corresponding to the first processing signal, and ending the calibration process. In this embodiment, in order to obtain more accurate calibration measurement data and avoid measurement deviations between the first measurement data and the actual weight value of the electronic device caused by unstable placement of the electronic device, the first measurement data may not be directly used as calibration measurement data. Instead, the first measurement data may be corrected firstly, and the corrected first measurement data may be used as calibration measurement data. For example, the first measurement data may be multiplied by a preset correction coefficient to obtain the corrected first measurement data. The preset correction coefficient may be determined based on the empirical error between the actual weight value of the electronic device and the measured weight value of the electronic device.

[0130] In some implementations, to further avoid false detections of whether an electronic device meets calibration measurement conditions, a third measurement threshold can be set based on the second measurement threshold. The second measurement threshold serves as an upper limit threshold, and the third measurement threshold serves as a lower limit threshold. The third measurement threshold can be set based on empirical values ​​of the electronic device's weight. In step S11a, the microprocessor detects whether the electronic device meets calibration measurement conditions based on the first processing signal output by the signal processing module. This can include: the microprocessor acquiring corresponding first measurement data based on the received first processing signal; if the first measurement data is less than the second measurement threshold and greater than or equal to the third measurement threshold, then it is determined that the electronic device meets the calibration measurement conditions. By setting the lower limit threshold in this implementation, if the user holds the electronic device in a suspended or tilted state after powering it on without performing a calibration measurement operation, it will be impossible to detect whether the electronic device meets the calibration measurement conditions, thus avoiding false detections of whether the calibration measurement conditions are met and improving the accuracy of calibration.

[0131] In one implementation, after step S11, the following steps are also included:

[0132] S15, determine whether the calibration process has timed out based on the current time and the power-on time of the electronic device;

[0133] S16. If the calibration process times out, obtain the calibration measurement data based on the processing signal corresponding to the current time output by the signal processing module, and end the calibration process.

[0134] In this embodiment, if calibration measurement data cannot be successfully obtained after entering the calibration process, it will lead to excessively long user waiting times, which is detrimental to user experience. This embodiment employs an automatic timeout exit mechanism, which sets a time threshold. If the time difference between the current time and the electronic device's startup time is greater than or equal to this threshold, the calibration process is determined to have timed out. Calibration measurement data is then obtained based on the processing signal corresponding to the current time, and the calibration process ends. Through this embodiment, the calibration process exits after a timeout, avoiding prolonged user waiting and improving user experience.

[0135] In one implementation, the electronic device also includes a display module, and after step S11 and before step S12, the following steps are also included:

[0136] S11d, the microprocessor sends calibration measurement prompt information to the display module, which is used to prompt the user to perform calibration measurement operations.

[0137] In the calibration measurement method of this embodiment, a calibration processing flow is configured. After detecting that the user has performed a calibration measurement operation, the electronic device is then checked to see if it meets the calibration measurement conditions. When the electronic device is detected to meet the calibration measurement conditions, calibration measurement data is obtained according to the corresponding second processing signal. Since the user has performed a calibration measurement operation, the calibration measurement data can be avoided from being collected when the electronic device is not in a flat position. This can solve the problem of low weighing accuracy and improve the weighing accuracy.

[0138] It should be noted that, in this embodiment of the application, for ease of distinction, the first processing signal is the signal output by the signal processing module after the electronic device is turned on and enters the calibration measurement process, and before it is determined that the user has performed the calibration measurement operation; the second processing signal is the signal output by the signal processing module after it is determined that the user has performed the calibration measurement operation in the calibration measurement process, and before it is determined that the electronic device meets the calibration measurement conditions.

[0139] The calibration and measurement method of this embodiment will be described in detail below, taking an electronic device as a weighing scale as an example:

[0140] When the electronic scale is powered on, it acquires the initial calibration data corresponding to the power-on time, which serves as the first zero point. At power-on, the electronic scale may be in a flat or non-flat position; for example, it may be held by the user and suspended in mid-air, fully lifted by the user and suspended in mid-air, or partially lifted by the user and tilted. Because the electronic scale may be in a non-flat position, it may fail to acquire the initial calibration data successfully, or the acquired initial calibration data may be inaccurate.

[0141] After the electronic scale is turned on, it enters the calibration measurement process. The microprocessor detects whether the electronic scale meets the calibration measurement conditions based on the first processing signal output by the signal processing module, and obtains the first detection result. If the first detection result indicates that the calibration measurement conditions are met, the calibration measurement data is directly obtained based on the first processing signal, and the calibration process exits. This is suitable for scenarios where the user raises the electronic scale (fully or partially) to power it on, obtains initial calibration data, and then places the electronic scale flat. In this case, the electronic scale is flat, and there is no need to detect whether the user has performed a calibration measurement operation.

[0142] If the first detection result indicates that the calibration measurement conditions are not met, the microprocessor detects whether the user has performed a calibration measurement operation based on the first processing signal output by the signal processing module, obtaining a second detection result. If the second detection result indicates that the user has performed a calibration measurement operation, the microprocessor detects whether the electronic scale meets the calibration measurement conditions based on the second processing signal output by the signal processing module, obtaining a third detection result. If the third detection result indicates that the calibration measurement conditions are met, the microprocessor acquires the calibration measurement data based on the second processing signal and exits the calibration process. This is applicable to scenarios where the user places the electronic device in a flat position before obtaining initial calibration data after powering it on. In this case, it is necessary to detect that the user has performed a calibration measurement operation to ensure that the electronic scale is in a flat position before performing the test to determine whether the calibration measurement conditions are met.

[0143] After the electronic scale is turned on, it enters the calibration measurement process. This process requires continuous monitoring to determine if it has timed out. If it does, the calibration measurement data is retrieved based on the processing signal corresponding to the current time output by the signal processing module, and the calibration process ends. This is suitable for scenarios where the user holds the electronic device in their hand after powering it on or places it flat before initial calibration data is obtained. In this case, to improve user experience, the calibration measurement process ends immediately upon timeout, regardless of its current stage.

[0144] In this embodiment, after the microprocessor enters the calibration process, it displays calibration measurement prompts to the user through the display module. The user can then perform calibration measurement operations based on these prompts. This implementation method improves calibration measurement efficiency.

[0145] This application embodiment also provides an electronic device 400, which includes a device body and a calibration measurement device 100 as described above disposed within the device body. The electronic device may be, but is not limited to, a weight scale, body fat scale, nutrition scale, pulse oximeter with weighing function, body composition analyzer, car with weighing function, smart wearable device with weighing function, and smart home device with weighing function. Smart wearable devices with weighing function include, but are not limited to, neck massagers, leg massagers, and waist massagers. Smart home devices with weighing function include, but are not limited to, smart sockets, smart robot vacuums, and smart lights. This electronic device, through a configured calibration processing flow, detects that a user has performed a calibration measurement operation, and then checks whether the electronic device meets the calibration measurement conditions. When the electronic device is detected to meet the calibration measurement conditions, calibration measurement data is obtained according to the corresponding second processing signal. Because the user has performed a calibration measurement operation, it avoids the problem of the calibration measurement data being collected when the electronic device is in a suspended or tilted state, thus solving the problem of unfavorable weighing accuracy and improving weighing accuracy.

[0146] In one implementation, the electronic device 400 can be an electronic scale, and further, the electronic scale can be a weight scale, body fat scale, or nutrition scale.
