[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0051] The present application provides a water outlet control method and device for a mineralized faucet, a faucet and a storage medium.

[0052] For example, the water outlet control device of the mineralized faucet is integrated on the mineralized faucet, and the mineralized faucet can collect biometric information; perform feature extraction on the biometric information to obtain biometric information; perform feature matching on the biometric information and a preset biometric template; if the feature matching is successful, determine the water quality control parameters based on the target biometric template in the biometric template that matches the biometric information; and control the water outlet of the mineralized faucet based on the water quality control parameters and the biometric information.

[0053] In one embodiment, see Figure 1 The mineralized faucet is mainly composed of the following parts: faucet body, display module, filter element assembly, control module, detection module, communication module and radar.

[0054] The faucet body is the main structure of the mineralized faucet, including a connecting part and a main body. The connecting part and the main body are connected by rotation, which is convenient for the user to adjust the angle and position of the faucet. An installation area is provided on the main body for installing a display module. At least one display area is provided on the connecting part or the main body for installing a light-emitting unit.

[0055] The display module is used to display the user interface, etc. The user interface can have multiple display areas to meet the display requirements of different information. A light-emitting unit can also be set in the display area to provide backlight or indication functions. The color or length can be changed according to the instructions of the control module to intuitively reflect the water quality status or remind the user to perform certain operations.

[0056] The detection module is arranged on the water supply channel, and is used to obtain the dissolved matter content value (for example, the total dissolved solid value or the conductivity) of the water supply channel, and transmit the obtained dissolved matter content value to the control module for processing. The detection module includes a detection meter.

[0057] The filter element assembly is used to mineralize the water flow in the water supply waterway. The filter element assembly is set in the water supply waterway to improve the water quality through the mineralized filter element, providing healthier and better tasting drinking water. The filter element assembly includes an inlet end and an outlet end, and the inlet end and the outlet end are respectively provided with a detector.

[0058] The control module is the intelligent core of the mineral faucet, which is connected to the display module, light-emitting unit, etc., and is used to control the color or length of the light-emitting unit and the display content of the display module. The control module can intelligently adjust the water quality according to the user's biological information to meet the user's personalized needs.

[0059] The communication module is used to communicate with the control module to achieve remote control and data transmission. The communication module can transmit the soluble substance content value to the smart device or server, so that users can view and manage it at any time.

[0060] Radar can be used to sense the user's approach or departure, thereby automatically turning off the faucet and achieving a more convenient and energy-saving water experience. Radar can also be used in combination with other water quality detection sensors to build a water quality detection system. When the water quality is abnormal, the radar can cooperate with the display module and the light-emitting unit to send out an early warning signal to remind the user to deal with it in time.

[0061] The mineralized faucet can be connected to a water purifier and users can conveniently obtain mineralized and purified drinking water through the mineralized faucet to meet the daily drinking water needs of the family.

[0062] The water outlet control method of the mineralized faucet provided in the present application is to collect biometric information; extract features from the biometric information to obtain biometric information; perform feature matching on the biometric information and a preset biometric template; if the feature matching is successful, determine the water quality control parameters based on the target biometric template that matches the biometric information in the biometric template; and control the water outlet of the mineralized faucet based on the water quality control parameters and the biometric information. In the water outlet control scheme of the mineralized faucet provided in the present application, the biometric information of the user can be collected and the biometric information can be deeply extracted to obtain unique biometric information; then the biometric information can be accurately matched with the pre-stored biometric template to ensure that only authorized users can operate; once the feature matching is successful, the water quality control parameters can be determined to meet the user's water demand in a personalized manner. It can be seen that by determining the water quality control parameters through biometric information, the mineralized faucet can avoid unauthorized use or misoperation of the mineralized faucet, save water resources, and at the same time, control the water outlet of the mineralized faucet to meet the personalized needs of the user, accurately control the water outlet, and improve the intelligence of the mineralized faucet.

[0063] It should be noted that the order of description of the following embodiments is not intended to limit the priority order of the embodiments.

[0064] A method for controlling water flow from a mineralized faucet comprises: collecting biological information; extracting features from the biological information to obtain biological characteristic information; performing feature matching between the biological characteristic information and a preset biological characteristic template; if the feature matching is successful, determining water quality control parameters based on a target biological characteristic template in the biological characteristic template that matches the biological information; and controlling water flow from the mineralized faucet based on the water quality control parameters and the biological characteristic information.

[0065] See also Figure 2 , Figure 2 The schematic diagram of the flow chart of the water outlet control method of the mineralized faucet provided in the present application. The specific flow chart of the water outlet control method of the mineralized faucet can be as follows:

[0066] 101: Collect biometric information.

[0067] Among them, biological information can be information used to identify, analyze and understand the characteristics and / or behaviors of organisms.

[0068] The biometric information may be fingerprint information, finger pressure information, gesture information, or voice information of a living being.

[0069] For example, a fingerprint identifier can be integrated on the mineralized faucet to collect fingerprint information of an organism; a pressure sensor can be integrated on the mineralized faucet to identify finger pressure information of an organism; a camera can be used to collect gesture information of an organism; and a microphone can be used to collect voice information of an organism.

[0070] 102: Extract features from the biological information to obtain biological feature information.

[0071] Feature extraction is the process of extracting information from biometric information that is useful for subsequent processing or analysis. The purpose of feature extraction is to convert biometric information into a form that is easier to analyze and understand, while reducing the dimension of biometric information and improving the efficiency of data processing. Biometric information can be used to verify whether the user is an authorized user. If the user is an authorized user, step 103 can be continued. Otherwise, a reminder is given, such as the need to collect biometric information again; for example, unauthorized personnel are prohibited from using it.

[0072] Exemplarily, assuming that the biometric information is fingerprint information, image processing algorithms may be used to extract features of the fingerprint information such as ridge patterns, minutiae (such as bifurcation points and terminals), etc.

[0073] Exemplarily, assuming that the biological information is speech information, speech recognition technology can be used to extract spectral features of the speech information, such as Mel-frequency cepstral coefficients.

[0074] In one embodiment, the biological information includes video information, and the step of extracting features from the biological information to obtain biological feature information includes:

[0075] Extracting a gesture image sequence from the video information;

[0076] Extracting gesture features from the gesture image sequence to obtain sub-gesture features corresponding to each frame of gesture image;

[0077] Synthesizing the sub-gesture features based on the time sequence of the gesture image sequence to obtain a gesture feature sequence;

[0078] The biometric feature information is obtained according to the gesture feature sequence.

[0079] The video information may include biometric information for controlling the mineralized faucet. The sub-gesture feature may be a basic component element / attribute of a single gesture action in the gesture image. The sub-gesture feature may include basic attributes such as shape, movement, position, and speed of the gesture.

[0080] When the user interacts with the mineral faucet, he makes a command gesture in front of the camera. At this time, the camera can capture the process of the user making the command gesture to obtain video information; then the mineral faucet obtains the video information and extracts the gesture image sequence; computer vision technology is used to extract features of each frame of the gesture image to obtain the sub-gesture features corresponding to each frame of the gesture image; then the gesture features are arranged in chronological order of the gesture image sequence to obtain a gesture feature sequence, and the gesture feature sequence is used as biometric information.

[0081] For example, suppose a user wants to control the mineral faucet at home through a specific command gesture, for example, first extend the index finger and then the middle finger. The intelligent mineral faucet captures the user's command gesture through the camera, and executes the corresponding control command according to the gesture feature sequence corresponding to the command gesture. Specifically, the mineral faucet extracts a gesture image sequence from the video information, that is, each frame contains an image of the user's gesture; for each frame of gesture image, computer vision technology (such as edge detection, contour tracking, gesture recognition algorithm) is used to extract key sub-gesture features, such as the shape and position of the index finger, the angle of the index finger relative to the palm, the shape and position of the middle finger, and the angle of the middle finger relative to the palm; the sub-gesture features of the two gesture actions are spliced ​​and synthesized in chronological order to form a gesture feature sequence of the command gesture, and the gesture feature sequence is used as biometric information.

[0082] The camera captures the command gesture and also collects the user's voice command, thereby forming video information. That is, in one embodiment, the method further includes:

[0083] Extracting voice information from the video information;

[0084] Extracting sound features from the voice information to obtain sound feature information;

[0085] The obtaining of the biometric feature information according to the gesture feature sequence includes:

[0086] The sound feature information and the gesture feature sequence are subjected to feature fusion to obtain the biometric feature information.

[0087] Among them, the voice information is a voice command used to control the mineral faucet.

[0088] First, the audio track can be separated from the video information to extract the voice information; then, the sound feature information in the voice information is extracted, such as Mel-frequency cepstral coefficients, pitch, rhythm, and intonation; finally, the sound feature information and gesture feature sequence are spliced ​​to obtain the biometric information.

[0089] For example, suppose the user's voice command is "hot water", and the corresponding gesture is to first extend the palm and then make an upward waving motion. Based on this, the audio track is extracted from the video information, and the sound features such as Mel Frequency Cepstral Coefficient (MFCC), pitch, rhythm and intonation are extracted to obtain the sound feature information, and the gesture features such as the shape of the palm, the trajectory and speed of the waving are extracted to obtain the gesture feature sequence, and the sound feature information and the gesture feature sequence are spliced ​​to form comprehensive biometric information.

[0090] 103: Perform feature matching between the biometric feature information and a preset biometric feature template.

[0091] A preset matching algorithm may be used to match the biometric information with a preset biometric template, and the matching result may be compared with a preset threshold. If the matching result meets the preset threshold, it indicates a successful match, such as if both the identity and the command match. If the matching result does not meet the preset threshold, it indicates a failed match, such as if neither the identity nor the command matches. The user may be prompted to re-collect the biometric information / prompt that unauthorized personnel are prohibited from using the device. The preset matching algorithm may include dynamic time warping, Euclidean distance, cosine similarity, support vector machine, neural network, and other algorithms.

[0092] For example, if the biometric feature information is sound feature information (ie, sound feature vector), a dynamic time warping algorithm may be used to perform feature matching between the sound feature vector and each sound vector to be compared in a preset biometric feature template.

[0093] For example, if the biometric information is a fingerprint feature vector (or a finger pressure feature vector, i.e., the size or number of finger pressure, etc.), the cosine similarity can be used to match the fingerprint feature vector (or finger pressure feature vector) with each fingerprint vector to be compared (or each finger pressure vector to be compared) in a preset biometric template.

[0094] For example, if the biometric information is a gesture feature sequence, a convolutional neural network may be used to match the gesture feature sequence vector with each gesture vector to be compared in a preset biometric template.

[0095] For example, if the biometric feature is a concatenated vector of sound feature information and a gesture feature sequence, the concatenated vector can be classified by a support vector machine to obtain a classification result, and the classification result can be matched with each classification result to be compared in the preset biometric feature simulation.

[0096] 104: If the feature matching is successful, determining the water quality control parameter based on the target biometric template in the biometric template that matches the biometric information.

[0097] The target biometric template may be a feature template that matches the biometric information. The water quality control parameter may be a parameter used to control the water quality of the water coming out of the mineral faucet. The water quality control parameter may include pH, temperature, total dissolved solids, conductivity, water flow, water volume, etc.

[0098] For example, user A makes a preset gesture in front of the mineral faucet (such as extending his palm to indicate a pH value of 5) and says "hot water 40°C", that is, the biometric information includes a concatenated vector of the gesture feature sequence and the sound feature information. The concatenated vector is input into the trained classification vector machine model for classification to obtain a classification result, which is used to represent the adjustment command of the water quality parameters. The classification result is matched with the classification result to be compared in the preset biometric template. If the feature matching is successful, the water quality control parameters are determined to be a pH value of 5 and a water temperature of 40°C according to the matched target biometric template.

[0099] 105: Control the water output of the mineralized faucet based on the water quality control parameter and the biometric information.

[0100] The water quality control parameters can be adjusted according to the biometric information, and then the water output from the mineralized faucet can be controlled based on the adjusted water quality control parameters.

[0101] For example, suppose user A likes to drink water with a pH value of 7.5 and a temperature of 25°C in the morning, and prefers water with a pH value of 7.0 and a temperature of 38°C in the evening, and the current water quality control parameters are water with a pH value of 7.0 and a temperature of 38°C. When user A stands in front of the mineral faucet, says "my water", and makes a "palm spread" gesture to request the water quality of personal preference, the identity of user A can be identified through the biometric information of user A and the time corresponding to the current biometric is morning, then according to the preference settings of user A, the pH value is adjusted to 7.5 and the water temperature is adjusted to 25°C.

[0102] In one embodiment, the controlling the water output from the mineralized faucet based on the water quality control parameter and the biometric information includes:

[0103] Determining water quality standard parameters based on the biometric information;

[0104] Adjust the water quality control parameter according to the water quality standard parameter;

[0105] The water output of the mineralized faucet is controlled according to the adjusted water quality control parameters.

[0106] The biometric information can be used for identity recognition, thereby obtaining a physical examination report associated with the recognized identity, determining the water quality standard parameters based on the physical examination report, thereby adjusting the water quality control parameters based on the water quality standard parameters, and controlling the water output of the mineralized faucet based on the adjusted water quality control parameters.

[0107] For example, in one application scenario, the user uploads the medical examination report to the health management database of the mineral faucet through the mobile terminal. Assume that after matching the biometric information, the water quality control parameter pH value is determined to be 7. After the user's identity is determined based on the biometric information, the user's medical examination report can be automatically obtained from the health management database, and the medical examination report is analyzed to determine that the user's water quality standard parameters are pH 7.5 and temperature 40°C to help regulate his body's acid-base balance. Finally, the water quality control parameters are updated to pH 7.5 and temperature 40°C.

[0108] In this embodiment, by adjusting the water quality control parameters through the water quality standard parameters, users can enjoy drinking water that meets their health needs, while also allowing users to pay more attention to and participate in their daily health management, which not only improves the convenience of drinking water, but also enhances the healthiness of drinking water, providing users with more comprehensive and personalized services.

[0109] In one embodiment, determining the water quality standard parameter according to the biometric information includes:

[0110] Performing feature analysis on the biometric feature information to obtain a feature analysis result;

[0111] Determining the physiological health status corresponding to the biometric information according to the feature analysis result;

[0112] The water quality standard parameters are determined based on the physiological health condition.

[0113] For example, assuming that the biometric information is a concatenated vector of sound feature information (such as pitch, rhythm, intonation, etc.) and gesture feature sequence (such as shape, motion trajectory, etc.), by comparing the biometric information with the user's healthy biological data, the comparison result shows that the user's voice is high and the gestures are slightly slow, and the physiological health condition is fatigue. The water quality standard parameters corresponding to the fatigue state are pH value 7.8 (helps relieve fatigue) and temperature 38°C (close to body temperature).

[0114] In this embodiment, the water quality standard parameters are determined by analyzing biometric information to determine the user's current physiological health status, so that the user can enjoy personalized care, help the user to better manage their health, and provide timely health intervention when necessary, thereby improving the intelligence level of the mineral faucet.

[0115] In one embodiment, the method further comprises:

[0116] If the matching is unsuccessful, a prompt message is generated to remind the user that the biometric information recognition is incorrect according to the prompt message.

[0117] For example, a user controls the water flow of a mineral faucet through a voice command, but the sound feature information of the voice command fails to match the sound vector to be compared in the preset biometric template, resulting in a match failure result; the sound feature information is classified to obtain a classification result, which indicates the reason for the sound match failure. If the reason for the match failure is environmental noise interference, the generated prompt message is "Please keep the environment quiet"; if the reason for the match failure is that the speaking volume is too low / too fast, the generated prompt message is "Increase the volume / reduce the speaking speed and issue the command again."

[0118] In one embodiment, the method further comprises:

[0119] Detecting water quality parameters of the water coming out of the mineralized faucet;

[0120] Displays the water quality parameters.

[0121] Among them, water quality parameters may include total dissolved solids, pH value, water temperature, water flow, water volume, etc.

[0122] In one embodiment, the water quality parameters can be fed back to a mobile terminal (such as a mobile phone or a tablet) associated with the mineralized faucet through a network for display. They can also be displayed through a display module provided on the mineralized faucet. They can also be voice broadcasted through the mineralized faucet / mobile terminal.

[0123] In one embodiment, the total dissolved solids value and pH value can be detected by using a TDS (Total Dissolved Solids) detector to detect drinking water. Figure 1 As shown, TDS detectors, namely, detector 1 (TDS1) and detector 2 (TDS2), can be respectively set upstream and downstream of the mineralized filter element set in the water purification equipment, and the mineralized filter element can be used to adjust the pH value of the drinking water solution. By calculating the difference ΔTDS between TDS1 and TDS2, and obtaining the solution pH value (PH value), i.e., water quality information, based on the difference ΔTDS. The relationship between the difference ΔTDS and the PH value is shown in Table 1.

[0124]

[0125]

[0126] Table 1

[0127] According to the difference ΔTDS and pH value in Table 1, we can get Figure 3 Specifically, by linearly fitting the ΔTDS-PH value curve, the following formula can be obtained, and the pH value of the solution can be obtained based on the difference ΔTDS according to the following formula:

[0128] f(ΔTDS)=a+b*ΔTDS

[0129] Where f(ΔTDS) represents the pH value of the solution, ΔTDS is the difference between TDS1 and TDS2, a is the source term constant, and b is the amplitude index. The source term constant and the amplitude index are experimentally measured. The TDS value measured by detector 2 can be used as the total dissolved solids value to be displayed.

[0130] In this embodiment, by displaying water quality parameters, not only can the water quality information provided to users be ensured to be accurate and timely, but users can also be reminded in time when the water quality does not meet health standards, thereby improving the safety of drinking water.

[0131] The above is the water outlet control process of the mineralized faucet of this application.

[0132] As mentioned above, the present application provides a method for controlling the water output of a mineralized faucet, by collecting biometric information; extracting features from the biometric information to obtain biometric information; matching the biometric information with a preset biometric template; if the feature matching is successful, determining the water quality control parameters based on the target biometric template that matches the biometric information in the biometric template; and controlling the water output of the mineralized faucet based on the water quality control parameters and the biometric information. In the water output control scheme of the mineralized faucet provided in the present application, the biometric information of the user can be collected and the biometric information can be deeply extracted to obtain unique biometric information; then the biometric information can be accurately matched with the pre-stored biometric template to ensure that only authorized users can operate; once the feature matching is successful, the water quality control parameters can be determined to meet the user's water demand in a personalized manner. It can be seen that by determining the water quality control parameters through biometric information, the mineralized faucet can be prevented from being used unauthorizedly or misoperated, saving water resources, and at the same time, the water output can be controlled to meet the personalized needs of the user, accurately control the water output, and improve the intelligence of the mineralized faucet.
