Description

Technical Field

[0001] This application relates to the technical field of smart water cups, and more particularly to a method for measuring water intake and a smart water cup. Background Technology

[0002] With the increasing public awareness of health and the popularization of smart hardware technology, smart water bottles, as an emerging personal health management tool, have received widespread attention from the market. One of their core functions is to automatically monitor users' drinking behavior, providing personalized drinking reminders and health suggestions to help users develop scientific drinking habits and maintain good hydration. Therefore, accurately and reliably measuring the actual amount of liquid consumed by users is the absolute prerequisite and data foundation for realizing all subsequent advanced health management functions (such as hydration status assessment, drinking pattern analysis, and precise hydration guidance).

[0003] However, existing smart water cups generally suffer from low accuracy in measuring water intake, which severely limits their application value in actual health management and user trust. Summary of the Invention

[0004] In view of this, the present application provides a method for measuring water intake and a smart water cup to solve the problem of low accuracy in water intake measurement in the prior art.

[0005] A first aspect of this application provides a method for measuring water consumption, applied to a smart water cup. The smart water cup includes a detachably connected cup and a base, the base including a weighing unit. The method includes:

[0006] The system acquires the measured weight, a first temperature, and a second temperature; wherein the measured weight represents the total weight of the water cup measured in real time by the weighing unit, the first temperature represents the real-time temperature of the weighing unit, and the second temperature represents the real-time temperature of the environment where the base is located.

[0007] Based on the first and second temperatures, the measured weight is corrected to obtain the corrected weight.

[0008] The amount of water consumed is determined based on the corrected weight and the movement of the water cup.

[0009] In one possible implementation, weight compensation is performed on the measured weight based on a first temperature and a second temperature to obtain a corrected weight, including:

[0010] The compensation weight is determined based on the first temperature, the second temperature, and the preset temperature drift model.

[0011] The correction weight is determined based on the measured weight and the compensation weight.

[0012] In one possible implementation, the base includes a top plate for supporting the water cup, and the weighing unit includes a plurality of weighing sensors spaced apart below the top plate;

[0013] To obtain the measured weight, including:

[0014] Obtain the weight values ​​of each weighing sensor, determine the sum of the weight values, and obtain the total weight;

[0015] The intermediate weight for correction is determined based on the product of the preset first correction parameter and the total weight.

[0016] The measured weight is obtained by summing the calibrated intermediate weight and the preset second calibration parameter.

[0017] In one possible implementation, the amount of water consumed is determined based on the corrected weight and the motion state of the water cup, including:

[0018] Obtain the water cup's identification information;

[0019] The weight of the water cup is determined based on the correspondence between the identification information and the pre-stored identification information and the weight of the water cup.

[0020] Determine the net liquid weight based on the calibrated weight and the weight of the water cup;

[0021] The amount of water consumed is determined based on the net liquid weight and the movement of the cup.

[0022] In one possible implementation, the base includes a motion sensing unit;

[0023] Determine the amount of water consumed based on the net liquid weight and the movement of the cup, including:

[0024] The motion of the water cup is detected by a motion sensing unit and / or a weighing unit to determine the motion state of the water cup; the motion state includes the water cup being picked up, the water cup being put down, and the drinking event;

[0025] If the current motion state of the water cup is that the water cup is picked up and the water cup meets the first preset condition, then the current motion state of the water cup is switched to a drinking event, and the current net liquid weight is determined as the initial weight for drinking.

[0026] If the current motion state of the water cup is a drinking event and the water cup meets the second preset condition, then the current motion state of the water cup is switched to the water cup being put down, and the current net liquid weight is determined as the weight at the end of drinking.

[0027] The amount of water consumed is determined based on the initial weight and the final weight of the water consumed.

[0028] In one possible implementation, the first precondition includes at least one of the following:

[0029] The weighing unit detected a continuous decrease in the overall weight of the water cup.

[0030] The weighing unit detected that the rate of decrease of the overall weight of the water cup was greater than the first speed threshold.

[0031] The motion sensing unit detected that the angle at which the water cup was tilted was greater than a preset angle.

[0032] The motion sensing unit detected that the water cup was tilted for a period exceeding a first preset time.

[0033] And / or, the second preset condition includes at least one of the following:

[0034] The weighing unit detects that the overall weight of the water cup changes less than a first weight threshold within a second preset time period.

[0038] If the motion sensing unit detects that the water cup has been picked up when the water cup is currently stationary, then the current motion state of the water cup will be switched to that of the water cup being picked up.

[0039] If the weighing unit detects that the overall weight of the water cup is continuously increasing or the rate of increase of the overall weight of the water cup is greater than the second speed threshold when the current motion state of the water cup is stationary, the current motion state of the water cup will be switched to a water filling event.

[0040] If the vibration time of the water cup is detected by the motion sensing unit when the current motion state of the water cup is stationary, the current motion state of the water cup is switched to the interference state and the detection of the water cup's motion is stopped.

[0041] When the current motion state of the water cup is when the water cup is put down, if the time when the motion state of the water cup is when the water cup is put down is greater than the fifth preset time or the weight change of the overall weight of the water cup detected by the weighing unit within the second preset time is less than the first weight threshold, then the current motion state of the water cup is switched to the stationary state.

[0042] If the vibration of the water cup ends when the current motion state of the water cup is in a disturbed state, the current motion state of the water cup will be switched to a stationary state if the motion sensing unit detects that the vibration of the water cup has ended.

[0043] When the water cup is in the process of adding water, if the weighing unit detects that the weight change of the water cup within a second preset time period is less than the first weight threshold, then the water cup's current motion state is switched to a stationary state.

[0044] In one possible implementation, the pre-stored correspondence between the identifier information and the weight of the water cup is obtained in the following way:

[0045] When the water cup is placed on the base, obtain the water cup's identification information;

[0046] When the identification information does not match the identification information in the database, a prompt message is sent to the terminal device. The prompt message is used to remind the user to check whether the water cup is empty. The database stores the identification information, the weight of the water cup, and the correspondence between the identification information and the weight of the water cup.

[0047] In response to the binding command sent by the terminal device, the weight of the water cup is measured by the weighing unit, and a correspondence between the identification information and the weight of the water cup is established based on the identification information and the weight of the water cup.

[0048] In one possible implementation, the net liquid weight is determined based on the corrected weight and the weight of the water cup, including:

[0049] Based on the net liquid weight, the cup is determined to be empty.

[0050] If the empty cup remains empty for more than a sixth predetermined time, the weight of the cup is remeasured by the weighing unit, and the correspondence between the identification information and the weight of the cup is updated based on the remeasured weight.

[0051] And / or, in response to the tare calibration command from the terminal device, the weight of the water cup is remeasured by the weighing unit, and the correspondence between the identification information and the weight of the water cup is updated based on the remeasured weight.

[0052] A second aspect of this application provides a smart water cup, comprising: a detachably connected water cup and a base, the base including a weighing unit that measures the overall weight of the water cup in real time;

[0053] The base also includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the method of the first aspect.

[0054] The beneficial effects of the embodiments in this application compared with the prior art are:

[0055] The water consumption measurement method of this application embodiment can acquire the measured weight, a first temperature, and a second temperature. Since the first temperature represents the real-time temperature of the weighing unit and the second temperature represents the real-time temperature of the environment where the base is located, the overall weight of the water cup measured in real-time can be corrected based on the real-time temperature of the weighing unit and the real-time temperature of the environment to obtain a corrected weight. Then, based on the corrected weight and the movement state of the water cup, the water consumption can be determined. Therefore, this application embodiment can compensate for temperature drift in the overall weight of the water cup and combine the overall weight of the water cup with its movement state. It can accurately measure water consumption when the overall weight of the water cup decreases and the movement state of the water cup also indicates drinking, is less susceptible to environmental interference, and maximizes the application value and user trust of smart water cups in actual health management, thereby improving the user experience.

[0075] See Figure 1 As shown in the figure, this application provides a structural schematic diagram of a smart water cup 1. The smart water cup 1 includes: a detachably connected water cup 11 and a base 12, the base 12 including a weighing unit 121 for real-time measurement of the overall weight of the water cup 11.

[0076] Specifically, the overall weight of the water cup 11 includes the weight of the water cup and the weight of the liquid contained within the water cup 11.

[0077] Optionally, the base 12 includes a top plate for supporting the water cup 11, and the weighing unit 121 includes a plurality of weighing sensors 1211 spaced apart below the top plate. The total weight of the water cup 11 can be obtained through the weighing sensors 1211, and the weight reduction can be converted into volume reduction by using water density to obtain the amount of water consumed. The base 12 of this embodiment is used to perform the water consumption measurement method of this embodiment.

[0078] See Figure 2 As shown, this application provides a flowchart of a method for measuring drinking water volume. The method for measuring drinking water volume in this application is applied to a smart water bottle 1. The smart water bottle 1 includes a detachably connected base 12 and a water bottle 11. The base 12 includes a weighing unit 121. Figure 2 As shown, the method for measuring drinking water volume includes steps S201 to S202.

[0079] S201. Obtain the measured weight, the first temperature, and the second temperature; wherein, the measured weight is used to represent the total weight of the water cup 11 measured in real time by the weighing unit 121, the first temperature is used to represent the real-time temperature of the weighing unit 121, and the second temperature is used to represent the real-time temperature of the environment where the base 12 is located.

[0080] Optionally, the base 12 is used to perform the water consumption measurement method of the embodiments of this application.

[0081] In some embodiments, the base 12 includes a top plate for supporting the water cup 11, and the weighing unit 121 includes a plurality of weighing sensors 1211 spaced apart below the top plate; acquiring the measured weight includes:

[0082] Obtain the weight values ​​of each weighing sensor 1211, and determine the sum of the weight values ​​to obtain the total weight;

[0083] The intermediate weight for correction is determined based on the product of the preset first correction parameter and the total weight.

[0084] The measured weight is obtained by summing the calibrated intermediate weight and the preset second calibration parameter.

[0085] Optionally, in this embodiment of the application, four weighing sensors 1211 may be used, and the four weighing sensors 1211 are evenly arranged below the top plate.

[0086] S202. Based on the first temperature and the second temperature, perform weight correction on the measured weight to obtain the corrected weight.

[0087] In some embodiments, weight compensation is performed on the measured weight based on a first temperature and a second temperature to obtain a corrected weight, including:

[0088] The compensation weight is determined based on the first temperature, the second temperature, and the preset temperature drift model.

[0089] The correction weight is determined based on the measured weight and the compensation weight.

[0090] Optionally, the weighing unit 121 further includes a signal processing circuit and an analog-to-digital conversion circuit. The signal processing circuit is used to amplify and filter the sensing data output by the weighing sensor 1211, and the analog-to-digital conversion circuit is used to convert the analog signal output by the signal processing circuit into a digital signal.

[0091] Optionally, the first temperature is measured by a first temperature sensor, and the second temperature is measured by a second temperature sensor. The first temperature sensor is located at the analog-to-digital conversion circuit, and the second temperature sensor is located at the base 12.

[0092] Optionally, the preset temperature drift model is a pre-stored temperature drift model obtained through factory calibration or self-learning.

[0093] S203. Determine the amount of water consumed based on the calibrated weight and the motion state of the water cup 11.

[0094] The water consumption measurement method of this application embodiment can acquire the measured weight, a first temperature, and a second temperature. Since the first temperature represents the real-time temperature of the weighing unit 121 and the second temperature represents the real-time temperature of the environment where the base 12 is located, the overall weight of the water cup 11 measured in real time can be corrected based on the real-time temperature of the weighing unit 121 and the real-time temperature of the environment to obtain the corrected weight. Then, based on the corrected weight and the motion state of the water cup 11, the water consumption can be determined. Therefore, this application embodiment can compensate for temperature drift in the overall weight of the water cup 11 and combine the overall weight of the water cup 11 with the motion state of the water cup 11. It can accurately measure the water consumption when the overall weight of the water cup 11 decreases and the motion state of the water cup 11 also indicates drinking, which is not easily affected by environmental interference. This enhances the application value and user trust of the smart water cup 111 in actual health management and improves the user experience.

[0095] See Figure 3 As shown, this application embodiment provides a flowchart for determining the amount of water consumed based on the corrected weight and the motion state of the water cup 11. Figure 3 As shown, the amount of water consumed is determined based on the corrected weight and the motion state of the water cup 11, including steps S301 to S304.

[0096] S301. Obtain the identification information of water cup 11.

[0097] Optionally, the water cup 11 is equipped with a label module, and the base 12 is equipped with an identification module. The base 12 has an MCU (Micro Controller Unit) inside, and the identification module is used by the base 12 to read the identification information corresponding to the label module.

[0098] S302. Determine the weight of the water cup based on the correspondence between the identification information and the pre-stored identification information and the weight of the water cup.

[0099] In some embodiments, the correspondence between the pre-stored identification information and the weight of the water cup is obtained in the following way:

[0100] When the water cup 11 is placed on the base 12, the identification information of the water cup 11 is obtained;

[0101] When the identification information does not match the identification information in the database, a prompt message is sent to the terminal device. The prompt message is used to remind the user to check whether the water cup 11 is empty. The database stores the identification information, the weight of the water cup, and the correspondence between the identification information and the weight of the water cup.

[0102] In response to the binding command sent by the terminal device, the weight of the water cup 11 is measured by the weighing unit 121, and a correspondence between the identification information and the weight of the water cup is established based on the identification information and the weight of the water cup.

[0103] Optionally, when the base 12 is powered on or the water cup 11 is placed, the MCU control and identification module of the base 12 attempts to read the label on the bottom of the water cup 11. If the reading is successful, the unique ID of the water cup 11 is obtained, and the tare weight of the water cup corresponding to that ID is queried from the memory of the MCU or obtained from the cloud server as the water cup weight and water cup capacity. If it is a new water cup 11, the user is prompted to bind it and record the tare weight through the App, and the user is guided to empty the water cup 11 before confirmation.

[0104] S303. Determine the net liquid weight based on the calibrated weight and the weight of the water cup.

[0105] In this embodiment, the net liquid weight is obtained by subtracting the weight of the water cup from the corrected weight.

[0106] S304. Determine the amount of water consumed based on the net liquid weight and the motion state of the water cup 11.

[0107] See Figure 4 As shown, this application embodiment provides a flowchart for determining the amount of water consumed based on the net liquid weight and the motion state of the water cup 11. The base 12 of this application embodiment includes a motion sensing unit, such as... Figure 4 As shown, the amount of water consumed is determined based on the net liquid weight and the motion state of the water cup 11, including steps S401 to S404.

[0108] S401, The motion of the water cup 11 is detected by the motion sensing unit and / or the weighing unit 121, and the motion state of the water cup 11 is determined; the motion state includes the water cup 11 being picked up, the water cup 11 being put down, and drinking events.

[0109] S402. If the current motion state of the water cup 11 is that the water cup 11 is picked up and the water cup 11 meets the first preset condition, then the current motion state of the water cup 11 is switched to a drinking event, and the current net liquid weight is determined as the initial weight for drinking.

[0110] S403. If the current motion state of the water cup 11 is a drinking event and the water cup 11 meets the second preset condition, then the current motion state of the water cup 11 is switched to the water cup 11 being put down, and the current net liquid weight is determined as the weight at the end of drinking.

[0111] S403. Determine the amount of water consumed based on the initial weight and the final weight of the water consumed.

[0112] Optionally, the motion sensing unit includes a six-axis IMU (Inertial Measurement Unit), which can be used to measure the acceleration and angular velocity of the base 12.

[0113] This application embodiment can determine the current state of the base 12, such as: stationary, picked up, put down, tilted, continuously vibrating, etc., and the corresponding motion state can be determined based on the current state. Detecting drastic changes in acceleration or angular velocity can determine the event of picking up / putting down the cup 11, detecting changes in tilt angle can determine the drinking action, and detecting high-frequency vibration can determine environmental interference.

[0114] This application embodiment can use a Kalman filter to estimate a smoother and more accurate "true" net liquid weight by using the net liquid weight as an observation and combining it with the motion state as input or state transition constraints. The state vector of the Kalman filter can include weight, rate of weight change, sensor bias, etc. When violent motion or vibration is detected, the weight of the weight observation can be reduced or state updates can be temporarily stopped.

[0115] In some embodiments, the first preset condition includes at least one of the following:

[0116] The weighing unit 121 detected that the overall weight of the water cup 11 continued to decrease;

[0117] The weighing unit 121 detected that the rate of decrease of the overall weight of the water cup 11 was greater than the first speed threshold.

[0118] The motion sensing unit detected that the angle at which the water cup 11 was tilted was greater than the preset angle.

[0119] The motion sensing unit detected that the water cup 11 was tilted for a period of time exceeding a first preset time.

[0120] In some embodiments, the second preset condition includes at least one of the following:

[0121] The weighing unit 121 detects that the overall weight change of the water cup 11 within a second preset time is less than the first weight threshold.

[0122] The motion sensing unit detects that the water cup 11 remains stationary for a third preset time.

[0123] This application embodiment can store the identified drinking events (timestamp, amount consumed) in the non-volatile memory of the MCU. The total daily consumption is calculated cumulatively, and the data is periodically synchronized to the user's app and the cloud server.

[0124] In some embodiments, the motion state of the water cup 11 also includes at least one of a stationary state, a disturbed state, and a water-adding event;

[0125] The motion state of the water cup 11 is determined by detecting the motion of the water cup 11 through the motion sensing unit and / or weighing unit 121, and the method further includes at least one of the following:

[0126] If the motion sensing unit detects that the water cup 11 has been picked up when the water cup 11 is currently in a stationary state, then the current motion state of the water cup 11 will be switched to the state where the water cup 11 has been picked up.

[0127] When the current motion state of the water cup 11 is a stationary state, if the weighing unit 121 detects that the overall weight of the water cup 11 continues to increase or the rate of increase of the overall weight of the water cup 11 is greater than the second speed threshold, then the current motion state of the water cup 11 is switched to a water filling event.

[0128] When the current motion state of the water cup 11 is a stationary state, if the vibration time of the water cup 11 detected by the motion sensing unit is greater than the fourth preset time, the current motion state of the water cup 11 will be switched to the interference state and the motion detection of the water cup 11 will be stopped.

[0129] When the current motion state of the water cup 11 is when the water cup 11 is put down, if the time when the motion state of the water cup 11 is put down is greater than the fifth preset time or the weight change of the overall weight of the water cup 11 detected by the weighing unit 121 within the second preset time is less than the first weight threshold, then the current motion state of the water cup 11 is switched to the stationary state.

[0130] If the vibration of the water cup 11 ends when the current motion state of the water cup 11 is in a disturbed state, the current motion state of the water cup 11 will be switched to a stationary state when the motion sensing unit detects that the vibration of the water cup 11 has ended.

[0131] When the current motion state of the water cup 11 is a water-adding event, if the weighing unit 121 detects that the weight change of the overall weight of the water cup 11 within a second preset time is less than the first weight threshold, then the current motion state of the water cup 11 is switched to a stationary state.

[0132] Specifically, if the weight change of the water cup 11 within a second preset time period is less than the first weight threshold, it indicates that the overall weight of the water cup 11 is no longer changing.

[0133] As an example, the base 12 maintains several states, such as "stationary state", "cup 11 picked up", "cup 11 put down", "drinking event", "water adding event", "interference state", etc. For example, various thresholds (rate, time, tilt angle, etc.) in the embodiments of this application need to be calibrated and optimized through a large amount of experimental data.

[0134] This application embodiment can combine the motion sensing unit and the weighing unit 121 to detect various movements of the water cup 11 and determine the motion state of the water cup 11, thereby facilitating accurate determination of the amount of water consumed.

[0135] In some embodiments, determining the net liquid weight based on the calibrated weight and the weight of the water cup includes:

[0136] Based on the net liquid weight, it is determined that water cup 11 is empty.

[0137] If the empty cup state lasts for more than a sixth predetermined time, the weight of the water cup 11 is remeasured by the weighing unit 121, and the correspondence between the identification information and the weight of the water cup is updated based on the remeasured weight.

[0138] And / or, in response to the tare calibration command of the terminal device, the weight of the water cup 11 is remeasured by the weighing unit 121, and the correspondence between the identification information and the weight of the water cup is updated based on the remeasured weight of the water cup.

[0139] This embodiment of the application can perform automatic tare calibration. When the base 12 is in a static state and the net liquid weight is close to 0 (e.g., within a small error range, such as ±2g), and this continues for a period of time, the MCU can automatically perform a tare operation to update the internal zero-point reference. Alternatively, when the user confirms that the water cup 11 is empty via an App or voice command, a tare calibration can be forced, and the tare weight record corresponding to the ID of the water cup 11 can be selectively updated to update the water cup weight.
