[0001] This invention relates to the field of breastfeeding assistance devices, specifically to a breastfeeding assistance device, method, and storage medium. Background Technology

[0002] During breastfeeding, especially for new mothers, challenges often arise such as difficulty in determining the balance between milk supply and demand, and low feeding efficiency. Therefore, breastfeeding aids have emerged to address these issues. These aids can help monitor milk parameters, providing mothers with data to adjust feeding methods and understand lactation status, which is crucial for ensuring successful breastfeeding.

[0003] In existing technologies, breastfeeding aids often only use sensors based on the principle of flow rate measurement to measure milk flow rate, and then calculate other milk parameters, such as milk flow rate and total milk volume, based on the milk flow rate.

[0044] Optionally, both the first flow velocity detection sensor assembly and the second flow velocity detection sensor assembly are optical sensor assemblies.

Even when the milk channel is not filled with milk, the milk parameters can be accurately determined, thereby improving the accuracy of the milk parameters.

[0076] The breastfeeding support device provided in this application will be described in detail below with reference to the accompanying drawings.

[0077] Please see Figure 1 , Figure 1 This is a schematic diagram of the breastfeeding support device provided in an embodiment of this application. Figure 1 As shown, the breastfeeding support device 1 includes a milk detection device 10, a control module 20, and a detection module 30. The control module 20 and the detection module 30 are communicatively connected.

[0078] Optionally, the control module and the detection module can be connected by wire or wireless means.

[0079] Please see Figure 2 and Figure 3 , Figure 2 This is a three-dimensional structural schematic diagram of the milk detection device provided in the embodiments of this application. Figure 3 This is a front view of the milk detection device provided in an embodiment of this application. Figure 2 and Figure 3 As shown, the milk detection device 10 includes a cover 11 and a milk channel section 12. One end of the milk channel section 12 is connected to the cover 11, and the other end of the milk channel section 12 is provided with a milk outlet 121 for milk to flow out. The milk channel section 12 is used to transport milk secreted by the user's nipple.

[0082] Optionally, the milk channel portion is used to accommodate at least part of the nipple, or the cover is used to accommodate at least part of the nipple, or the cover is used to accommodate the nipple while the milk channel portion is not used to accommodate the nipple.

[0083] Furthermore, the cover includes a mounting part for mounting on a baby bottle. In this case, the milk detection device is a nipple device, and the baby draws milk from the bottle through the sucking head.

[0084] Optionally, the milk detection device is a breast shield of the breast pump, the shield being designed to fit the user's breast, and the milk outlet being connected to the milk storage container in the breast pump.

[0085] Please see Figure 4 , Figure 4 This is a partial cross-sectional schematic diagram of the milk channel portion equipped with a detection module provided in an embodiment of this application. Figure 4 The protective element is not shown in the diagram to illustrate the detection module. Figure 4 As shown, optionally, the detection module 30 is disposed on the milk channel section 12, and the detection module 30 is used to detect the milk and obtain detection result data.

[0086] Figure 4 The cross-section is Figure 3 Section line AA in the diagram. Due to the minute size of the specific structure. Figure 4This is a schematic diagram of the principle; the shape of the milk channel in the diagram may differ from the actual shape of the milk channel.

[0087] like Figure 4 As shown, optionally, the milk channel portion 12 includes a channel wall 122 and a milk channel 123 formed by the channel wall 122 for milk to flow out. The channel wall 122 is provided with... Figure 3 Milk outlet 121.

[0088] Optionally, the detection module 30 includes a flow rate detection unit 31 and a level detection unit 32. The flow rate detection unit 31 is used to detect the milk flow rate, and the level detection unit 32 is used to detect the milk level. In this way, milk parameters can be accurately determined even when the milk channel is not full, thereby improving the accuracy of milk parameters.

[0089] Optionally, the flow rate detection unit does not directly contact the milk. This avoids contamination of the milk and prevents milk residue from remaining on the flow rate detection unit, thus preventing any impact on detection accuracy.

[0090] Optionally, the flow rate detection unit is disposed on the channel wall of the milk channel section without directly contacting the outer surface of the milk or is embedded in the channel wall.

[0091] like Figure 4 As shown, optionally, the flow rate detection unit 31 is embedded in the channel wall 122 and does not directly contact the milk.

[0092] Optionally, the flow rate detection unit includes at least one flow rate detection sensor assembly.

[0093] Optionally, the flow rate detection unit includes multiple flow rate detection sensor components, which are sequentially arranged in the milk channel section along the milk flow direction. In this way, compared to using only a single flow rate detection sensor component, flow rate detection data can be acquired from multiple locations, thereby improving the accuracy of milk parameters.

[0094] Optionally, the number of flow rate detection sensor components may be 2, 3, or 4, etc.

[0095] like Figure 4 As shown, by way of example, the flow rate detection unit 31 includes a first flow rate detection sensor assembly 311 and a second flow rate detection sensor assembly 312, which are sequentially arranged in the milk channel section along the milk flow direction L1.

[0096] Optionally, the liquid level detection unit 32 is disposed between the first flow rate detection sensor assembly 311 and the second flow rate detection sensor assembly 312.

[0097] Optionally, the flow rate detection unit is at least partially located at the bottom of the milk channel. The bottom of the milk channel is the portion that contacts the milk channel when it flows under gravity. In this way, the flow rate detection unit can still accurately detect the milk volume even when the milk volume is low.

[0098] like Figure 4 As shown, the direction of gravity is vertically downward. The first flow velocity detection sensor assembly 311 and the second flow velocity detection sensor assembly 312 are disposed at the bottom of the milk channel section 12. The bottom of the milk channel section 12 is also the part that contacts the milk channel section 12 when the milk Z flows under the action of gravity.

[0099] Optionally, the flow rate detection unit includes at least one flow rate detection sensor component selected from capacitive sensor components, optical sensor components, photoacoustic sensor components, ultrasonic sensor components, and calorimetric sensor components. That is, the flow rate detection sensor component can be one of the above-mentioned sensor component types.

[0100] Since the dielectric constant of milk is much greater than that of air, when milk flows through the milk channel, the capacitance of the capacitive sensor component increases significantly, thus enabling the capacitive sensor component to detect the flow of milk through the milk channel.

[0101] Optionally, the capacitive sensor assembly includes at least one of a parallel plate capacitive sensor assembly, a cylindrical capacitive sensor assembly, a spiral capacitive sensor assembly, and an interdigitated capacitive sensor assembly.

[0102] Optionally, the parallel plate capacitive sensor assembly includes two relatively parallel electrodes, which are disposed in contact with the channel wall of the milk channel. In this way, the parallel plate capacitive sensor assembly has a simple structure, is easy to install, and the electrode placement in contact with the channel wall reduces interference from the external environment, thus improving the measurement accuracy of the parallel plate capacitive sensor.

[0103] Parallelism can refer to approximate parallelism.

[0104] Optionally, the electrode adheres to the outer surface of the channel wall that does not directly contact the milk.

[0105] Optionally, the electrode adheres to the inner surface of the channel wall, directly contacting the milk.

[0106] Optionally, the electrode can be a flexible electrode. This allows for a higher degree of adhesion between the electrode and the channel wall, minimizing environmental interference and improving measurement accuracy.

[0107] Optionally, the capacitive sensor assembly includes coplanar electrodes.

[0108] Optionally, the capacitive sensor assembly includes interdigitated electrodes, which are intersecting comb-shaped electrodes that can increase the edge electric field effect and improve the sensitivity of the capacitive sensor assembly on a single plane.

[0109] Please see Figure 5 , Figure 5 This is a schematic diagram of a spiral capacitive sensor assembly provided in an embodiment of this application. Exemplarily, the spiral capacitive sensor assembly 313 includes spiral electrodes. In this way, the length of the detection area and the detection sensitivity can be increased.

[0110] Optionally, the spiral electrode can be spirally wound around the outer or inner surface of the channel wall or embedded in the channel wall. For example, the spiral electrode is spirally wound around the outer surface of the channel wall 122 that does not directly contact the milk.

[0111] Please see Figure 6 , Figure 6 This is a schematic diagram of the cylindrical capacitive sensor assembly provided in an embodiment of this application. Figure 6 As shown, exemplarily, the cylindrical capacitive sensor assembly 314 includes cylindrical electrodes. Specifically, the cylindrical capacitive sensor assembly 314 includes an inner arc-shaped electrode plate 3141, an outer cylindrical electrode plate 3142, and electrode posts 3143. The electrode posts 3143 are used to connect to the control module and are connected to the inner arc-shaped electrode plate 3141. The outer cylindrical electrode plate 3142 is disposed on the outer surface of the channel wall 122 that does not directly contact the milk, while the inner arc-shaped electrode plate 3141 is disposed on the inner surface of the channel wall 122 that directly contacts the milk. There can be multiple inner arc-shaped electrode plates 3141, for example, there can be two inner arc-shaped electrode plates 3141, in which case there are also two electrode posts 3143. The two inner arc-shaped electrode plates 3141 are arranged opposite each other and spaced apart by a preset distance.

[0112] The optical sensor assembly is used to detect whether milk is flowing through the milk channel and other milk parameters based on the signal characteristics of the laser.

[0113] The ultrasonic sensor assembly detects whether milk is flowing through the milk channel by emitting and receiving ultrasonic waves and detecting changes in acoustic impedance caused by the change of medium from air to liquid.

[0114] Optionally, the photoacoustic sensor assembly includes a laser emitter and an acoustic detector. The laser emitter illuminates the milk channel with a laser beam. As the milk flows through the milk channel, particles in the milk absorb the laser energy and undergo instantaneous thermal expansion, thereby generating an ultrasonic signal. The acoustic detector detects the ultrasonic signal. The control module then calculates the milk flow rate based on the time-of-flight or correlation between the laser and ultrasonic signals. The photoacoustic sensor assembly is well-suited for detecting opaque milk.

[0115] Optionally, the calorimeter sensor assembly includes a temperature measuring unit and a heating unit. The temperature measuring unit includes a first temperature sensor and a second temperature sensor, and the heating unit is located between the first temperature sensor and the second temperature sensor.

[0116] When no milk flows through the milk channel, the heat generated by the heating unit diffuses symmetrically in all directions. Therefore, the first and second temperature sensors measure the same temperature, resulting in zero temperature difference. When milk flows through the milk channel, it carries the heat generated by the heating unit downstream. This forced convection heat transfer caused by the flow disrupts the original thermal equilibrium, causing the temperature of the second temperature sensor to be higher than that of the first temperature sensor. The temperature difference between the two sensors is directly related to the milk flow rate: the faster the milk flows, the more heat is carried away, and the greater the temperature difference. By measuring this temperature difference, the milk flow rate can be accurately calculated.

[0117] Optionally, the heating unit includes at least one of a resistance temperature detector (RTD), a thin-film heater, a thick-film heater, a ceramic heater, a laser heater, a microwave heater, and an infrared radiation heater. The thick-film heater can be printed on a ceramic substrate or a metal substrate.

[0118] Optionally, the temperature sensor includes at least one of a thermistor, a resistance temperature detector, a thermocouple, a thermal diode, and an optical temperature sensor.

[0119] Optionally, the flow rate detection sensor assembly is an optical sensor assembly.

[0120] Optionally, the optical sensor assembly includes a light emitter and a light receiver, with the light emitter and the light receiver facing each other. The laser emitted by the light emitter can pass through the milk channel and be received by the light receiver.

[0121] Optionally, an optical sensor assembly integrates a light emitter and a light receiver.

[0122] Optionally, the optical sensor assembly is configured to emit a laser beam toward the milk channel and receive scattered light signals generated by biological particles in the milk after laser irradiation. For example... Figure 4 As shown, when milk Z flows through the milk channel section 12, the biological particles 21 (such as fat particles or protein particles) in the milk scatter laser light. The optical sensor assembly receives the scattered laser signal, i.e., the scattered light signal. Based on the signal characteristics of the scattered light signal, the control module can determine whether milk has flowed through the milk channel section.

[0123] Optionally, the direction in which the optical sensor assembly emits the laser is perpendicular to the direction of milk flow. For example, the direction L2 of the laser emitted by the first optical sensor assembly 311 is perpendicular to the direction L1 of milk flow. In this way, the sensitivity of the optical sensor assembly can be improved.

[0124] Optionally, the control module is configured to determine the milk flow rate among the milk parameters by analyzing detection signals from multiple optical sensor components using an optical cross-correlation method. Specific methods will be described in detail in the section on breastfeeding support methods below.

[0125] Optionally, the liquid level detection unit includes at least one liquid level detection sensor assembly.

[0126] Optionally, one level detection sensor assembly corresponds to a detection height in the milk channel section.

[0127] Optionally, the liquid level detection unit includes multiple liquid level detection sensor assemblies, with at least two assemblies having different detection heights within the milk channel. This reduces the impact of noise and improves the accuracy of the milk level height compared to using a single liquid level detection sensor assembly.

[0128] Optionally, the number of liquid level detection sensor components can be 2, 3, 4 or 5, etc.

[0129] Optionally, multiple liquid level detection sensor assemblies are arranged sequentially in a vertical direction, with each assembly corresponding to a preset detection height. This approach further reduces the impact of noise and improves the accuracy of the milk level measurement.

All the liquid level detection sensor assemblies are positioned at different heights within the milk channel section 12, and therefore have different detection heights.

[0131] Optionally, the level detection unit does not directly contact the milk. This avoids contamination of the milk and prevents milk residue from remaining on the level detection unit, thus preventing any impact on detection accuracy.

[0132] like Figure 4 As shown, exemplarily, the liquid level detection unit 32 is disposed on the outer surface of the channel wall 122 that does not directly contact the milk.

[0133] Optionally, the liquid level detection unit is embedded in the channel wall and does not directly contact the milk.

[0134] Optionally, the liquid level detection unit includes at least one liquid level detection sensor component selected from capacitive sensor components, optical sensor components, ultrasonic sensor components, and electrode sensor components. That is, the type of liquid level detection sensor component can be one of the above-mentioned sensor component types.

[0135] The electrode sensor assembly includes two opposing electrodes. Since milk is conductive, when the milk level rises and submerges the two electrodes, a conductive path is formed, thus turning on the circuit of the electrode sensor assembly, enabling the electrode sensor assembly to detect the flow of milk.

[0136] Optionally, the liquid level detection sensor assembly is a capacitive sensor assembly, which includes at least one of a parallel plate capacitive sensor assembly, a cylindrical capacitive sensor assembly, a spiral capacitive sensor assembly, and an interdigitated capacitive sensor assembly.

[0137] like Figure 2 As shown, optionally, the milk detection device 10 also includes a protective section 13, which at least covers the detection module. In this way, the protective section can prevent the infant from directly contacting the detection module, prevent the detection module from short-circuiting due to contact with external liquids, protect the infant's safety, and thus improve the safety of the breastfeeding aid device.

[0138] Optionally, the detection module and the control module are connected by wires, and the protection unit includes a wire groove for the wires to pass through.

[0139] Optionally, the detection module and the control module are connected via printed circuit boards.

[0140] Optionally, the breastfeeding aid also includes a power supply module for supplying power to the detection module and the control module.

[0141] Optionally, the power supply module includes a battery.

[0142] Optionally, the power supply module can be connected to AC power.

[0143] Optionally, the control module and the milk detection device can be separately configured, detachably connected, or fixedly connected. By separating the control module from the milk detection device or allowing for a detachable connection, the weight of the milk detection device can be reduced, improving user comfort.

[0144] Optionally, the control module is also communicatively connected to the prompting module, and the control module is also used to control the prompting module to perform preset operations related to milk parameters. In this way, reference information can be provided to the user based on milk parameters.

[0145] Optionally, the control module is also connected to the prompting module via wired or wireless connection.

[0146] Optionally, the breastfeeding support device also includes a prompting module.

[0147] Optionally, the prompt module is located on an electronic device other than a breastfeeding aid, such as a mobile phone.

[0148] Optionally, the prompting module includes at least one of a display component, a voice prompt component, and a vibration component.

[0149] Optionally, the control module is also used to control the display component to display milk parameters using images, animations, and text.

[0150] Optionally, the control module is also used to control the voice prompt component to announce milk parameters via voice.

[0151] Optionally, the control module is also used to control the vibration component to indicate milk parameters through vibration. The vibration intensity can be one or more types.

[0152] Optionally, the milk detection device may be made of silicone or latex.

[0153] Alternatively, the milk detection device may also be made of temperature-sensitive materials.

[0154] like Figure 2 and Figure 3 As shown, optionally, the cover 11 includes a reinforcing portion 111, the thickness of which is greater than the thickness of the area of ​​the cover 11 excluding the reinforcing portion 111. In this way, the shape of the cover can be better maintained.

[0155] Optionally, the reinforcing part 111 is provided at the bottom of the cover 11. In this way, the center of gravity of the milk detection device can be lower than that of the milk channel, making it less likely for the milk channel to slip off the nipple.

[0156] Optionally, the control module is used to determine milk parameters based on the detection result data.

[0157] Optionally, the milk parameters include at least one of milk flow rate, duration of milk flow through the milk channel, milk flow rate, and total milk volume. Total milk volume includes at least one of the total volume of a single milk stream and the cumulative total milk volume.

[0158] This application also provides a method for assisting breastfeeding, applied to the breastfeeding assisting device described above.

[0159] Please see Figure 7 , Figure 7 This is a schematic flowchart of the breastfeeding support method provided in the embodiments of this application. Figure 7 As shown, the breastfeeding support method includes steps S100 to S200.

[0160] Step S100: Obtain the detection result data from the detection module.

[0161] The detection module includes a flow rate detection unit and a liquid level detection unit.

[0162] Step S200: Determine milk parameters based on the test results data.

[0163] Optionally, the milk parameters include the milk level height, and step S200 includes step S210.

[0164] Step S210: Determine the liquid level height of the milk based on the liquid level detection data in the detection result data.

[0165] Among them, the liquid level detection data is the data obtained by the liquid level detection unit from detecting the milk.

[0166] Optionally, the liquid level detection unit includes at least one liquid level detection sensor assembly, and one liquid level detection sensor assembly corresponds to a detection height in the milk channel section. Step S210 includes steps S211 to S212.

[0167] Step S211: Determine whether each liquid level detection sensor component has detected milk flow based on the liquid level detection data.

[0168] For example, when the liquid level detection sensor component is a capacitive sensor component, and the capacitance value of the capacitive sensor component is determined to be greater than a preset judgment threshold based on the liquid level detection data, it is determined that the liquid level detection sensor component has detected the flow of milk.

[0169] For example, when the liquid level detection sensor assembly is an optical sensor assembly, and it is determined based on the liquid level detection data that the optical sensor assembly receives a scattered light signal generated by biological particles in the milk after laser irradiation, it is determined that the optical sensor assembly has detected the flow of milk.

[0170] For example, when the liquid level detection sensor assembly is an ultrasonic sensor assembly, and it is determined based on the liquid level detection data that the ultrasonic signal emitted by the ultrasonic transmitter of the ultrasonic sensor assembly reaches the ultrasonic receiver through the milk, it is determined that the ultrasonic sensor assembly has detected the flow of milk.

[0171] For example, when the liquid level detection sensor assembly is an electrode-type sensor assembly, and it is determined based on the liquid level detection data that there is conductivity between the two electrodes of the electrode-type sensor assembly, it is determined that the electrode-type sensor assembly has detected the flow of milk.

[0172] Optionally, when it is determined that no level detection sensor assembly detects milk flow, the milk level is determined to be 0.

[0173] Step S212: Determine the milk level height based on the preset detection height corresponding to all the liquid level detection sensor components that detect milk flow.

[0174] In this way, compared to using only one liquid level detection sensor component for calculation, the impact of noise can be reduced and the accuracy of milk level height can be improved.

[0175] Optionally, the maximum value among the preset detection heights corresponding to all liquid level detection sensor components that have detected milk flow is determined. Based on the preset detection heights corresponding to each liquid level detection sensor component, it is determined whether all liquid level detection sensor components with detection heights not lower than the maximum value have detected milk flow. If so, the maximum height is determined as the milk level height. Otherwise, the second largest value among the preset detection heights corresponding to all liquid level detection sensor components that have detected milk flow is selected. Then, based on the preset detection heights corresponding to each liquid level detection sensor component, it is determined whether all liquid level detection sensor components with detection heights not lower than the second largest value have detected milk flow. If so, the maximum height is determined as the milk level height. Otherwise, the third largest value among the preset detection heights corresponding to all liquid level detection sensor components that have detected milk flow is selected, and so on, until the final milk level height is determined. This method avoids misjudgments caused by accidental milk splashing onto the liquid level detection sensor components, improving the accuracy of the milk level height.

[0176] like Figure 4 As shown, exemplarily, when milk Z flows through the milk channel section 12, the first liquid level detection sensor assembly 321, the second liquid level detection sensor assembly 322, the third liquid level detection sensor assembly 323, and the fourth liquid level detection sensor assembly 324 all detect the flow of milk, and the preset detection height corresponding to the fourth liquid level detection sensor assembly 324 is the maximum value among all detection heights. At this time, all liquid level detection sensor assemblies with a detection height not lower than this maximum value, including the first liquid level detection sensor assembly 321, the second liquid level detection sensor assembly 322, and the third liquid level detection sensor assembly 323, also detect the flow of milk, and this maximum height can be determined as the liquid level height of the milk.

[0177] Please see Figure 8 , Figure 8 This is a cross-sectional schematic diagram of the milk channel section as milk flows through, according to an embodiment of this application. For example... Figure 8 As shown, in Figure 4 In the case shown, the milk level height H can be determined, and the milk level height H is also... Figure 4 The detection height corresponding to the fourth liquid level detection sensor component 324 in the middle.

[0178] For example, if the first liquid level detection sensor assembly 321, the second liquid level detection sensor assembly 322, the third liquid level detection sensor assembly 323, and the fifth liquid level detection sensor assembly 325 all detect the flow of milk, the preset detection height corresponding to the fifth liquid level detection sensor assembly 325 is the maximum value among all detection heights. At this time, all liquid level detection sensor assemblies with a detection height not lower than this maximum value include the first liquid level detection sensor assembly 321, the second liquid level detection sensor assembly 322, the third liquid level detection sensor assembly 323, and the fourth liquid level detection sensor assembly 324. However, if the fourth liquid level detection sensor assembly 324 does not detect the flow of milk, it can be concluded that the milk has only splashed onto the fifth liquid level detection sensor assembly 325. In this case, the detection height corresponding to the third liquid level detection sensor assembly 323 is determined as the liquid level height of the milk.

[0179] Optionally, the liquid level detection unit includes a liquid level detection sensor assembly, and step S210 includes determining the liquid level height of the milk based on the liquid level detection data of the liquid level detection sensor assembly.

[0180] For example, when the liquid level detection sensor assembly is a capacitive sensor assembly, the capacitance value of the liquid level detection sensor assembly is determined based on the liquid level detection data of the assembly, and the liquid level height of the milk is calculated based on the capacitance value using a preset calculation method. Because the capacitance value of the capacitive sensor assembly is related to the dielectric constant of the milk, the higher the liquid level height in the milk channel, the greater the dielectric constant. Therefore, the liquid level height of the milk is positively correlated with the capacitance value of the capacitive sensor assembly, and the liquid level height of the milk can be determined based on the capacitance value.

[0181] Optionally, the milk parameters also include the cross-sectional area of ​​the milk channel corresponding to the milk level height, and step S200 further includes step S220.

[0182] Step S220: Determine the cross-sectional area of ​​the milk channel corresponding to the milk level based on the milk level height and the preset correspondence between the milk level height and the cross-sectional area of ​​the milk channel.

[0183] In this context, the cross-sectional area of ​​the milk channel corresponding to the milk level height is the area of ​​the effective cross-section (also known as the flow section) of the milk channel. The effective cross-section of the milk channel refers to the section perpendicular to the milk flow direction and filled with milk. The area of ​​this section varies with the milk level height and the shape of the channel wall. Therefore, by using the above method, the accuracy of the cross-sectional area can be improved, thereby improving the accuracy of other milk parameters calculated based on the cross-sectional area.

[0184] like Figure 8As shown, region S1 is filled with milk, and the area of ​​region S1 is the cross-sectional area of ​​the milk channel portion 12 corresponding to the milk level height H. At this time, the milk does not completely fill the milk channel 122, and the area of ​​region S1 is smaller than the area inside the outline of the milk channel 122.

[0185] Optionally, the milk parameters include the milk flow rate, and step S200 includes step S230.

[0186] Step S230: Determine the milk flow rate based on the flow rate detection data in the detection result data.

[0187] Optionally, the flow velocity detection unit includes a first flow velocity detection sensor assembly and a second flow velocity detection sensor assembly. The flow velocity detection data includes first detection signal data from the first flow velocity detection sensor assembly and second detection signal data from the second flow velocity detection sensor assembly. Step S310 includes steps S231 to S232. The above-described optical cross-correlation method includes the contents of steps S231 to S232.

[0188] Step S231: Determine the movement time of milk between the first flow rate detection sensor assembly and the second flow rate detection sensor assembly based on the first detection signal data and the second detection signal data.

[0189] Optionally, both the first flow velocity detection sensor assembly and the second flow velocity detection sensor assembly are optical sensor assemblies. The optical sensor assembly is configured to emit a laser into the milk channel and receive the scattered light signal generated by biological particles in the milk after being irradiated by the laser, thereby obtaining detection signal data.

[0190] Optionally, step S231 includes steps S2311 to S231.

[0191] Step S2311: Calculate the sampling interval value that maximizes the cross-correlation function of the first detection signal data and the second detection signal data.

[0192] As milk flows sequentially through the first and second flow velocity sensor components, each component measures a typical value (e.g., the maximum value) representing the flow of milk at different times. By calculating the sampling interval that maximizes the cross-correlation function between the first and second flow velocity sensor components, compared to calculating the time of travel based solely on a single data point from the flow velocity detection data, the influence of noise can be reduced, and the sampling interval between the typical data points in the first and second flow velocity sensor components can be accurately determined, thereby improving the accuracy of the travel time.

[0193] Optionally, the time series of data points in the first and second detection signal data are aligned based on the same sampling time, and then the sampling interval value that maximizes the cross-correlation function of the first and second detection signal data is calculated. In this case, the number of data points in the first and second detection signal data is the same.

[0194] Optionally, the formula for calculating the cross-correlation function is:

[0195] in, Indicates by The determined values ​​of the cross-correlation function between the first and second detection signal data. Indicates the sampling interval value. This indicates the number of data points in the first detection signal data. Represents a counting variable. Indicates the first detection signal data Data points, Indicates the first in the second detection signal data Data points.

[0196] Optionally, the cross-correlation function is a normalized cross-correlation function. This reduces the impact of data fluctuations caused by changes in milk concentration on the sampling interval values, thus improving the accuracy of the sampling interval values.

[0197] For example, when the cross-correlation function is a normalized cross-correlation function, the formula for calculating the cross-correlation function is: , in, This represents the mean value of the data points in the first detection signal data. This represents the mean value of the data points in the second detection signal data.

[0198] Optionally, since the sampling frequency of the flow rate detection unit is limited, the time point at which milk flows through the flow rate detection sensor component may fall between the sampling time points of two data points, and the actual sampling interval value may not be a positive integer. To improve calculation accuracy, an interpolation algorithm can be used to correct the sampling interval value.

[0199] Optionally, the interpolation algorithm includes subsampling interpolation algorithms, such as Gaussian fitting interpolation algorithms, parabolic fitting interpolation algorithms, bicubic interpolation algorithms, and spline interpolation algorithms.

[0200] Optionally, step S2311 includes steps (2311.1) to (2311.3).

[0201] (2311.1) Calculate the initial sampling interval value that maximizes the cross-correlation function of the first and second detection signal data.

[0202] The initial sampling interval is a positive integer. The formula for calculating the cross-correlation function is as described above.

[0203] (2311.2) Calculate the correction amount of the initial sampling interval value based on the initial sampling interval value and the cross-correlation function.

[0204] Optionally, step (2311.2) includes steps (2311.2) to (2311.4).

[0205] (2311.2.1) Calculate the first value of the cross-correlation function based on the initial sampling interval.

[0206] The first value is obtained by substituting the initial sampling interval value into the calculation formula of the cross-correlation function.

[0207] (2311.2.2) The second value of the cross-correlation function is calculated based on the initial sampling interval value and the first preset value using the first calculation method.

[0208] Optionally, the result of adding the initial sampling interval value to the first preset value is used as the sampling interval value variable and substituted into the calculation formula of the cross-correlation function to obtain the second value.

[0209] Optionally, the first preset value is 1, 2, or 3, etc.

[0210] (2311.2.3) The third value of the cross-correlation function is calculated based on the initial sampling interval value and the second preset value using the second calculation method.

[0211] Optionally, the second preset value may be the same as or different from the first preset value.

[0212] Optionally, the second preset value is 1, 2, or 3, etc.

[0213] Optionally, the result of subtracting the second preset value from the initial sampling interval value is used as the sampling interval value variable and substituted into the calculation formula of the cross-correlation function to obtain the third value.

[0214] (2311.2.4) Calculate the correction amount of the initial sampling interval value based on the first value, the second value and the third value.

[0215] Optionally, an interpolation algorithm is used to calculate the correction amount of the initial sampling interval value based on the first value, the second value, and the third value.

[0216] For example, the formula for calculating the correction amount is: , in, Indicates the correction amount. Indicates the first value. Indicates the second value. This represents the third numerical value.

[0217] (2311.3) The final sampling interval value is calculated based on the initial sampling interval value and the correction amount.

[0218] Optionally, the initial sampling interval value is increased by a correction amount to obtain the final sampling interval value.

[0219] By using the above method, the sampling interval value does not have to be an integer, which can improve the calculation accuracy of the sampling interval value, and thus improve the accuracy of the milk flow rate calculated based on the sampling interval value.

[0220] Step S2312: Determine the movement time of milk between the first flow velocity detection sensor assembly and the second flow velocity detection sensor assembly based on the sampling interval value and the preset sampling period parameter of the flow velocity detection unit.

[0221] The sampling period parameter includes the sampling time interval or sampling frequency.

[0222] Optionally, the sampling interval value can be multiplied by the sampling time interval to obtain the movement time of the milk between the first flow rate detection sensor assembly and the second flow rate detection sensor assembly.

[0223] Optionally, the sampling interval value is divided by the sampling frequency to obtain the movement time of the milk between the first flow rate detection sensor assembly and the second flow rate detection sensor assembly.

[0224] Step S232: Determine the milk flow rate based on the motion time and the preset distance between the first flow rate detection sensor component and the second flow rate detection sensor component.

[0225] In this way, compared to using only one flow rate sensor component to calculate milk flow rate, the impact of noise can be reduced and the accuracy of milk flow rate can be improved.

[0226] Optionally, the milk flow rate can be obtained by dividing the distance between the first and second flow rate sensor components by the travel time. In this case, the unit of milk flow rate is a unit representing linear flow velocity. For example, the unit of milk flow rate is millimeters per second (mm / s).

[0227] Optionally, when the flow velocity detection sensor assembly is an optical sensor assembly, the milk flow velocity can be determined based on the principle of Doppler frequency shift. Specifically, the laser signal scattered by the milk will generate a Doppler frequency shift. By measuring the magnitude of this Doppler frequency shift, the movement velocity of biological particles in the milk can be directly calculated, thereby obtaining the milk flow velocity.

[0228] Optionally, when the flow rate detection sensor assembly is a photoacoustic sensor assembly, the milk flow rate can be calculated based on the time of flight or cross-correlation function of the laser signal and the ultrasonic signal.

[0229] Optionally, the milk parameters include the cross-sectional area of ​​the milk channel corresponding to the milk level height, the milk flow rate, and the milk flow rate, and step S200 includes step S240.

[0230] Step S240: Determine the milk flow rate based on the cross-sectional area of ​​the milk channel corresponding to the determined milk level height and the milk flow velocity.

[0231] Optionally, the milk flow rate can be obtained by multiplying the cross-sectional area of ​​the milk channel corresponding to the milk level height by the milk flow velocity.

[0232] Optionally, the milk flow rate is determined based on the cross-sectional area of ​​the milk channel corresponding to the determined milk level, the milk flow velocity, and a preset calibration coefficient. The calibration coefficient is used to correct for uneven distribution of the milk flow velocity within the milk channel. This method improves the accuracy of the milk flow rate.

[0233] Optionally, the milk flow rate can be obtained by multiplying the cross-sectional area of ​​the milk channel corresponding to the milk level height by the milk flow rate and a preset calibration coefficient.

[0234] Optionally, step S200 may further include steps S251 to S253.

[0235] Step S251: If multiple streams of milk are detected within a preset time period, determine the duration of each stream of milk flowing through the milk channel based on the detection result data.

[0236] Optionally, the time information of a single stream of milk flowing through the flow rate detection sensor component is identified based on the flow rate detection data in the detection result data. The time information includes the start time of the single stream of milk arriving at the flow rate detection sensor component and the end time of the stream of milk leaving the flow rate detection sensor component. The duration of the milk flowing through the milk channel is determined based on the time information of any one flow rate detection sensor component.

[0237] Step S252: Calculate the total amount of milk for each stream based on the duration of each stream of milk flowing through the milk channel and the milk flow rate.

[0238] Optionally, the milk flow rate of a single stream of milk is determined in the above manner at a preset time interval, and the integral of the milk flow rate with respect to time is calculated based on the milk flow rate of the single stream of milk determined at multiple time points. The integration interval is the interval corresponding to the duration of the milk flow through the milk channel section, and the total milk volume of the milk stream is obtained.

[0239] Optionally, the total amount of milk in a stream can be obtained by multiplying the duration of the milk flow through the milk channel by the milk flow rate of that stream.

[0240] Step S253: Calculate the total amount of milk from multiple streams to obtain the cumulative total amount of milk within a preset time period.

[0241] Optionally, the milk parameters include at least one of the following: milk level height, milk flow rate, duration of milk flow through the milk channel, milk flow rate, and total milk volume. Total milk volume includes at least one of the following: the total volume of a single milk stream and the cumulative total milk volume.

[0246] Optionally, the milk parameters include the milk flow rate, and step S340 includes step S341.

[0247] Step S341: Determine the milk flow rate based on the detection data.

[0248] Optionally, the detection unit includes a first detection sensor assembly and a second detection sensor assembly, the detection data includes first detection signal data of the first detection sensor assembly and second detection signal data of the second detection sensor assembly, and step S341 includes steps S3411 to S3412.

[0249] Step S3411: Determine the movement time of milk between the first detection sensor assembly and the second detection sensor assembly based on the first detection signal data and the second detection signal data.

[0250] Step S3412: Determine the milk flow rate based on the motion time and the preset distance between the first detection sensor component and the second detection sensor component.

[0251] The contents of steps S3411 to S3412 are the same as those of steps S231 to S232.

[0252] Optionally, both the first and second detection sensor components are optical sensor components. The optical sensor components are configured to emit a laser into the milk channel and receive the scattered light signal generated by biological particles in the milk after being irradiated by the laser, thereby obtaining detection signal data.

[0253] Optionally, the milk parameters also include milk flow rate, and step S340 includes step S342.

[0254] Step S342: Determine the milk flow rate based on the milk flow rate and the preset size parameters of the milk channel.

[0255] Optionally, the cross-sectional area of ​​the milk channel is determined based on the size parameters of the milk channel, and the milk flow rate is obtained by multiplying the milk flow velocity by the cross-sectional area of ​​the milk channel.

[0256] Optionally, dimensional parameters include the diameter, radius, or cross-sectional area of ​​the milk channel portion.

[0257] Optionally, the detection unit includes at least two detection sensor components, and step S340 includes steps S343 to S344.

[0258] Step S343: Identify the time information of a single stream of milk flowing through the detection sensor component based on the detection data.

[0259] The time information includes the start time of a single milk stream arriving at the sensor component and the end time of a single milk stream leaving the sensor component.

[0260] Step S344: Determine the duration of a single stream of milk flowing through the milk channel based on the time information of any one of the detection sensor components.

[0261] Optionally, step S340 may further include steps S345 to S347.

[0262] Step S345: If multiple streams of milk are detected within a preset time period, determine the duration of each stream of milk flowing through the milk channel based on the detection data.

[0263] Step S346: Calculate the total amount of milk for each stream based on the duration of each stream of milk flowing through the milk channel and the milk flow rate.

[0264] Step S347: Calculate the total amount of milk from multiple streams to obtain the cumulative total amount of milk within a preset time period.

[0265] The contents of steps S345 to S347 are the same as those of steps S251 to S253.

[0266] Optionally, the milk parameters include at least one of the following: milk level height, milk flow rate, duration of milk flow through the milk channel, milk flow rate, and total milk volume. Total milk volume includes at least one of the following: the total volume of a single milk stream and the cumulative total milk volume.

[0267] In summary, this application has the following advantages: 1. The detection module includes a flow rate detection unit and a liquid level detection unit, which can simultaneously detect the milk flow rate and the milk level height. Even when the milk channel is not filled with milk, the milk parameters can be accurately determined, thereby improving the accuracy of the milk parameters.

[0268] 2. By using a liquid level detection unit that includes multiple liquid level detection sensor assemblies, with at least two liquid level detection sensor assemblies having different detection heights in the milk channel, the influence of noise can be reduced and the accuracy of the milk level height can be improved compared to using a single liquid level detection sensor assembly.

[0269] 3. By calculating the sampling interval value that maximizes the cross-correlation function of the first and second detection signal data, compared to calculating the motion time based solely on the value of a single data point of the flow velocity detection data, the influence of noise can be reduced, and the sampling interval value between typical data points in the first and second flow velocity detection sensor components can be accurately determined, thereby improving the accuracy of the motion time.

[0270] 4. By calculating the final sampling interval value based on the initial sampling interval value and the correction amount, the sampling interval value does not have to be an integer, which can improve the calculation accuracy of the sampling interval value, and thus improve the accuracy of the subsequent milk flow rate calculated based on the sampling interval value.
