Therefore, adequate water intake is essential for the health of the body. Generally, the recommended daily water intake for adults is about two liters, and the actual demand is also affected by many factors, including age, gender, weight, activity level, climatic conditions, etc. However, with the accelerated pace of life, people often forget to drink water, resulting in dehydration of the body and affecting physical health. Traditional water cups do not have the function of measuring water intake, so they cannot remind people to replenish water intake in time when they forget to drink water.

[0003] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0047] Water is the source of life. Adults need to drink about 2 liters of water every day. However, with the accelerated pace of modern life, people often forget to drink water. On the one hand, there is no regular reminder, so people ignore drinking water. On the other hand, the thirst signal of the human body is delayed. When you drink water when you are thirsty, your body is already moderately dehydrated.

[0048] Ordinary water cups cannot remind people to drink water regularly. Water cups are of different sizes, and the naked eye cannot directly detect the amount of water drunk each time. In view of the edible nature of water, contact liquid level sensors cannot be used to ensure hygiene. The cost of non-contact sensors is too high, and they can only be used in industry, and consumer products cannot be popularized. The present invention can count the amount of water drunk every day (accurate to milliliters) through a low-cost acceleration sensor, and can also intelligently set the amount of water drunk at different times of the day. If the amount is not reached, it reminds people to drink water, which greatly improves the quality of drinking water for users.

[0049] Exemplary Methods

[0050] This embodiment provides a method for monitoring water intake, which can be applied to a water cup. Figure 1 As shown, the method comprises the following steps:

[0051] Step S100, measuring movement data of the water cup by an acceleration sensor, wherein the movement data is the position, movement speed and acceleration data from when the water cup escapes from the horizontal plane to when it returns to the horizontal plane;

[0052] In one embodiment, a capacitive MEMS (Micro-Electro Mechanical System) acceleration sensor is used as an acceleration sensor. The capacitive MEMS acceleration sensor is a 3D acceleration sensor that can measure three-dimensional velocity and acceleration. MEMS integrates micro-machining technology and sensor technology, and can realize miniaturization, low power consumption and high-precision tilt sensor, acceleration sensor and posture measurement. The capacitive MEMS acceleration sensor is connected to a fixed electrode through a spring through an internal movable micro-mass block. When the sensor is subjected to acceleration, the mass block will move due to inertia, causing the distance between the mass block and the fixed electrode to change. In this way, the MEMS acceleration sensor determines the acceleration of the water cup from breaking away from the horizontal plane to returning to the horizontal plane by measuring the capacitance change between the mass block and the fixed electrode. At the same time, the moving speed of the water cup can be calculated by recording the acceleration. MEMS posture measurement is to measure the acceleration and angular velocity of the object through sensors such as accelerometers and gyroscopes, and then calculate the position, velocity and posture of the object through mathematical algorithms (such as integration).

[0053] In one embodiment, the capacitive MEMS acceleration sensor can be placed at any position in the water cup. If the capacitive MEMS acceleration sensor is not placed horizontally, it only needs to be corrected for the horizontal plane to monitor the drinking action. Specifically, before using the capacitive MEMS acceleration sensor to measure the movement data of the water cup, it is necessary to first establish a coordinate system for the capacitive MEMS acceleration sensor, that is, determine the positions of the three axes X, Y, and Z, and confirm that the surface in the horizontal direction is a horizontal plane, that is, the initial state when the water cup is placed flat. When the water cup is placed flat and no displacement occurs, it is considered that the user has not drunk water, so there is no need to collect movement data. When the water cup breaks away from the horizontal plane, it is considered that the user has picked up the water cup to prepare or is drinking water, and the movement data at this time needs to be collected until the user puts down the water cup, that is, when the water cup returns to the horizontal plane, it is considered that the user has finished drinking water, and the collection of movement data can be ended.

[0054] In one implementation, the following steps are included before step S100 in this embodiment:

[0055] Step M100, establish a user ID, and update the action template corresponding to the user ID through teaching and learning, wherein the action template includes the user ID, an action trajectory curve and a preset error threshold, wherein the action trajectory curve is used to represent the relationship between the drinking action and the cup posture, moving speed and acceleration, and the user ID is the identity identification mark of the current user of the water cup.

[0056] Specifically, the age, weight, health status and living habits of users of water cups are different, which will lead to different drinking habits of users. Therefore, a separate file should be established for each user by identifying the user ID to analyze the drinking situation in a personalized way. At the same time, the actions of each user from picking up the water cup to drinking water will also be different. This embodiment establishes an action template for each user ID, which helps to more accurately capture the user's drinking action and calculate the user's drinking amount.

[0057] Specifically, through the teaching learning method, action templates are established and updated for each user. The teaching learning method provides a simple and direct way of trajectory planning: by observing the user's action demonstration, combined with appropriate machine learning methods for modeling and learning, the ability to complete the corresponding task is acquired. This method can greatly reduce the user's learning and use costs. The teaching learning method includes the following processes: before learning, the movement data of the water cup is measured by an acceleration sensor as teaching data; during the learning stage, due to the mismatch between the size and movement ability of humans and robots, it is necessary to solve the human-machine correspondence problem of teaching data; then, the teaching data is modeled to obtain the most suitable motion model in different scenarios; finally, the learned model is used to generate a motion trajectory that adapts to the new task scenario, that is, the motion trajectory curve.

[0058] In this embodiment, the action trajectory curve obtained by teaching and learning is stored in the action template in a one-to-one correspondence with the user ID. The action trajectory curve is the motion model of the user drinking water. It records the cup posture, movement speed and acceleration data during the user's drinking process, from picking up the cup, starting to drink water, drinking water, finishing drinking water to putting the cup flat. Because each action will be different, the error threshold is set to allow fuzzy recognition of the user's drinking action.

[0059] In one implementation, step M100 in this embodiment includes the following steps:

[0060] Step M101, obtaining configuration instructions, guiding the user to complete corresponding demonstration actions multiple times according to the configuration instructions and obtaining action data, wherein the action data is the position, movement speed and acceleration of the water cup, and the configuration instructions include starting to drink water, drinking water and ending to drink water;

[0061] Specifically, a complete drinking process may include holding the cup, drinking in small sips, drinking in large gulps, drinking all at once, finishing drinking, and putting the cup down. Configuration instructions may also be configured to start drinking, drinking, and finishing drinking. By configuring instructions to guide users to complete drinking demonstration actions step by step and multiple times and obtain action data, it is conducive to more accurate capture of action features.

[0062] For example, the configuration instruction can be to start drinking water, set the execution number to 10 times, and guide the user to complete the action of holding the cup with the left or right hand, standing, sitting or lying according to the demonstration action, and measure the position, movement speed and acceleration of the cup as teaching data through the acceleration sensor. For example, when the user picks up the cup, the acceleration sensor measures that the cup begins to move, and records the position, movement speed and acceleration of the cup. These action data represent the action of holding the cup in the hand. When the cup is close to the mouth, the speed will slow down and finally stop. At this time, the collected action data represents that the cup has reached the mouth. Through teaching learning, the control system can learn the user's position, movement speed and acceleration when holding the cup, drinking water in small sips, drinking water in large gulps, drinking all at once, finishing drinking water and putting the cup down. By learning the above data, the user's common actions of drinking water can be mastered. Configuration instructions can be issued from the control end, and the control end and the cup are connected through the resume Bluetooth to transmit control instructions, action data and movement data.

[0063] Step M102, analyzing the motion data to obtain a motion trajectory curve corresponding to the configuration instruction, wherein the motion trajectory curve includes a starting drinking motion trajectory curve, a drinking motion trajectory curve, and an ending drinking motion trajectory curve;

[0064] Step M103: update the motion trajectory curve in the motion template corresponding to the user ID.

[0065] Specifically, because the action data is discrete data, it is also necessary to abstract it into a linear function (mathematical expression) in order to discover the characteristic laws of the action. In this embodiment, by analyzing the action data, the discrete action data can be fitted into an action trajectory curve. Through the action trajectory curve, a continuous function is obtained, which is more conducive to mathematical expression. Because when calculating the amount of water a user drinks, the node for starting to drink water and the node for ending to drink water need to be clear, so by fitting the start drinking action trajectory curve and the end drinking action trajectory curve, preparations can be made for subsequent action judgments. In addition, the drinking action trajectory curve also helps to improve the accuracy of drinking action judgments. By storing the action trajectory curve obtained from a user's action data in the action template of this user, an action archive can be established for the user to improve the accuracy of recognition.

[0066] In one implementation, step M102 in this embodiment includes the following steps:

[0067] Step M1021: Use a dynamic time warping algorithm to align the motion data, and use a spline function to fit the motion data to obtain the motion trajectory curve.

[0068] Specifically, the dynamic time warping algorithm finds the best match between two sequences by elastically stretching or compressing the time series, allowing nonlinear time alignment, so that even sequences that are offset on the time axis can be effectively compared and matched. The dynamic time warping algorithm performs data alignment on the action data and then performs data fitting, which can not only provide accurate fitting of the data points, but also ensure the smooth transition of the action trajectory curve at the connection point. In this embodiment, cubic splines are used to fit the start drinking action trajectory curve, the drinking action trajectory curve, and the end drinking action trajectory curve from the action data. Each curve is in a three-dimensional coordinate system, the x-axis of the coordinate system represents the acceleration of the water cup movement, the y-axis represents the speed of the water cup movement, and the z-axis represents the inclination angle between the water cup and the horizontal plane.

[0069] Step S200, calculating a single drinking amount of water according to the movement data;

[0070] Specifically, after determining the start and end times of drinking water, the change in the water cup's tilt angle can be obtained from the mobile data. The change in the amount of water in the cup can be calculated through the tilt angle of the water cup, and the user's single drinking amount can be obtained.

[0071] For example, in the process of fitting curves as described in the above example, the accelerometer is fixed at any position of the cup. When the cup is tilted 5 degrees, it stops. The accelerometer is connected to the control end via Bluetooth. The control end sends configuration instructions to let the cup learn the user's drinking action and recognize the various states of the cup. During the learning process, the data of the accelerometer is recorded to determine the horizontal placement state, movement state (speed, acceleration) and time of the cup, and the tilt angle when the movement stops. During the drinking process, if the cup is just picked up without drinking, the tilt angle changes in a small range. The action trajectory curve can be used to determine that the user has not drunk. If the cup is drunk in one gulp, the tilt angle is equal to or greater than 90 degrees. The action trajectory curve can be used to determine that the user has drunk in one gulp. The movement state (speed, acceleration) and time are obtained again, and then it is placed horizontally. The action trajectory curve can be used to determine that the user has finished drinking. This is a complete drinking process. The amount of water drunk is calculated from the tilt angle difference when the movement stops.

[0072] In one embodiment, the amount of water a user drinks at a time can also be calculated based on the tilt angle of the water cup. First, measure the capacity of the water cup. When the water cup is tilted and the water in the cup begins to flow out, record the tilt angle, that is, the angle of the cup when the cup is full of water, so as to obtain the tilt angle of the water cup with 100% water. In the same way, increase the tilt angle of the water cup to obtain the tilt angles of the water cup at different water volumes, such as 80% water volume, 50% water volume, and 30% water volume. Summarize the tilt angles of the water cup at different water volumes to obtain the corresponding relationship between the angle and the amount of water. When the user drinks water, the maximum value of the tilt angle of the water cup each time the user drinks water can be obtained based on the position of the water cup in the mobile data, and then compare the maximum value of the tilt angle of the water cup when the user drinks water with the corresponding relationship between the above angle and the amount of water to obtain the amount of water remaining in the water cup. By calculating the difference in the amount of remaining water each time you drink water, you can get the amount of water a user drinks at a time.

[0073] It should be noted that the tilt angle when drinking water is usually slightly larger than the angle when sampling. Therefore, when summarizing the correspondence between the angle and the amount of water, this embodiment adds a preset compensation angle Δθ to the tilt angle of the water cup for correction.

[0074] In one implementation, step S200 in this embodiment includes the following steps:

[0075] Step S201, matching the movement data with the action template to determine the start and end of a drinking action;

[0076] Step S202: obtaining the position of the water cup at the time of starting to drink water according to the drinking action, and obtaining the tilt angle of the water cup at the time of starting to drink water according to the position of the water cup at the time of starting to drink water;

[0077] Step S203, obtaining the position of the water cup at the time of ending drinking according to the drinking action, and obtaining the tilt angle of the water cup at the time of ending drinking according to the position of the water cup at the time of ending drinking;

[0078] Step S204: Calculate the amount of water drunk at a single time according to the difference between the tilt angle of the water cup at the start of drinking and the tilt angle of the water cup at the end of drinking.

[0079] For example, after obtaining the mobile data, a number of data blocks are obtained from the mobile data through a sliding time window, where the time window should be consistent with the action execution time of the action trajectory curve. When the data block matches the start drinking action trajectory curve in the action template, this time window is determined to be the user's start drinking time. The mobile data occurring at this time represents the start drinking action, and the position of the water cup at this time is recorded to obtain the tilt angle of the water cup at the start drinking time.

[0080] For example, when the data block matches the trajectory curve of the drinking action in the matching of the action template, this time window is determined to be the user's drinking time, and the movement data generated at this time represents the drinking action. The movement data generated at this time represents the drinking action, and the position of the water cup at this time is recorded to obtain the tilt angle of the water cup at the drinking time.

[0081] Specifically, a water cup is usually a cylinder, so the amount of water reduced in the water cup, that is, the amount of water drunk, can be calculated through the bottom area, height, and the difference between the tilt angle of the water cup when drinking starts and when drinking ends.

[0082] In one implementation, step S201 in this embodiment includes the following steps:

[0083] Step S2011, drawing a real-time action curve according to the movement data;

[0084] Step S2012, calculating the distance difference between the real-time action curve and the starting drinking action trajectory curve to obtain a first distance difference value;

[0085] Step S2013: if the first distance difference is less than the error threshold, it is determined that the user starts drinking water, the drinking start action is obtained, and the distance difference between the real-time action curve and the drinking end action trajectory curve is continuously calculated to obtain a second distance difference;

[0086] Step S2014: If the second distance difference is less than the error threshold, it is determined that the user has finished drinking water, and the drinking end action is obtained.

[0087] Specifically, a number of curves of the same length as the time window of the starting drinking action trajectory curve are intercepted in the real-time action curve by sliding the time window, and the distance difference between the intercepted real-time action curve and the starting drinking action trajectory curve is calculated in the sliding order. In this embodiment, an area graph is used to represent the first distance difference. When the area of ​​the area graph in a single time window is less than a preset error threshold, it can be considered that the user has started drinking water. After determining the drinking time, it is necessary to continue to monitor when the user stops drinking water. The same method is used to calculate the distance difference between the real-time action curve intercepted in the sliding order and the ending drinking action trajectory curve to obtain a second distance difference. The second distance difference is represented by an area graph. When the area of ​​the area graph in a single time window is less than a preset error threshold, it can be considered that the user has finished drinking water. In this way, intelligent judgment of drinking water actions is achieved.

[0088] Step S300: Generate a water intake report and a reminder message based on the single water intake.

[0089] In one implementation, step S300 in this embodiment includes the following steps:

[0090] Step S301: Obtain the user's physical indicators according to the user ID, wherein the physical indicators include height, weight, age and health indicators;

[0091] Step S302, calculating the amount of water to be consumed daily according to the physical indicators;

[0092] Step S303, calculating the total daily water intake based on the single water intake, and generating a water intake report based on the total daily water intake;

[0093] Step S304, calculate the difference between the daily water intake and the total daily water intake, and if the absolute value of the difference is greater than the preset water intake threshold, generate a reminder message that the water intake should be adjusted; if the absolute value of the difference is less than or equal to the preset water intake threshold, generate a reminder message that the water intake should be adjusted.

[0094] Specifically, a professional doctor can formulate a drinking plan based on the user's height, weight, age and health indicators. The drinking plan may include the amount of water that should be drunk every day. In a natural day, the user's full-day drinking amount can be calculated by summarizing the single drinking amount. The full-day drinking amount, single drinking amount, drinking frequency and other data can be summarized to generate a drinking report, which is convenient for users or doctors to check their daily drinking situation. When the user's drinking amount does not meet the requirements of the drinking plan, a reminder message to adjust the drinking amount will be issued to remind the user to drink water in time.
