[0026] Figure 1 is a schematic diagram of a switch element control method according to an embodiment of the present application, Figure 1 As shown, the switch element control method of the embodiment of the present application includes the following steps 101 to 104: Step 101, continuously collecting and preprocessing first touch signals acting on the touch keys according to a preset period to obtain a first number of first key values; Step 102, obtaining a similarity between a first fitting curve formed according to the first number of first key values ​​and each second fitting curve in a feature library; Step 103, determining the type of the first touch signal according to the relationship between the similarity and the similarity threshold; Step 104: When it is determined that the first touch signal belongs to the first type of signal, control the corresponding switch element to not operate.

[0027] Among them, each second fitting curve in the feature library is a curve obtained by subtracting a curve formed by a group of key values ​​obtained by connecting and collecting and preprocessing the first and second signals acting on the touch key according to the preset period from a curve formed by a group of key values ​​obtained by connecting and collecting and preprocessing the third type of signals acting on the touch key according to the preset period, wherein the first type of signal includes a signal generated by non-artificial touching of the touch key; the second type of signal includes a signal jointly generated by non-artificial touching of the touch key and artificial touching of the touch key, and a signal generated by artificially touching the touch key when the touch key is in an initial state; the third type of signal includes a signal generated when the touch key is in an initial state.

[0028] The embodiment of the present application compares the actual touch signal with the touch signal of the preset type in the feature library. When it is determined that the actual touch signal is a signal generated by non-human touching the touch key, the corresponding switch element is controlled not to operate, thereby avoiding false triggering caused by non-human touching the key and improving the reliability of the touch key. In addition, when comparing, the curve formed by the continuous collection of multiple actual touch signals is compared with the curve formed by the preset type of touch signal. Compared with the comparison of the average value of the continuous collection of multiple actual touch signals with the average value of the preset type of touch signal, it reflects the dynamic change process of the force acting on the touch key, which is closer to the actual situation, thereby further improving the reliability of the touch key.

[0029] The control method of the switch element is applied to an electrical device, and the electrical device may include: a panel, at least one touch button, and at least one switch element, and the at least one touch button cooperates with the panel. The touch button and the panel here can be matched with each other. Abutment refers to two objects being in close contact or close together, with no gap between their surfaces, or one object being firmly pressed on another object. Exemplarily, for example, the touch button in this type of electrical device includes a spring, one end of the spring is in abutment with the panel, and the other end of the spring can be connected to the input end of the touch chip through a resistor, and the output end of the touch chip is connected to the switch element. The type and quantity of the switch element are not limited, and can be set accordingly according to the function of the electrical device. For example, it can be a solenoid valve, or a switching transistor, a thyristor, etc., which is not limited here.

[0030] In step 101, the preset period may be, for example, 10ms. Continuous acquisition may be performed once every 10ms, once after 10ms, and once after another 10ms. Since the total time taken for continuous acquisition is relatively short, the user experience will not be affected in terms of the touch key response speed. For example, if the acquisition is performed 6 times in a row and calculated as once every 10ms, the total time taken is 60ms. However, multiple continuous acquisitions of touch signals can obtain multiple key values ​​for curve fitting, and more accurately exclude interference sources or more accurately determine whether it is a human touch.

[0031] In an exemplary embodiment, when the touch key is pressed, the resistive touch sensor detects a change in resistance, causing the output analog voltage to change, thereby reflecting the magnitude of the signal acting on the touch key through the change in the analog voltage. In order to digitally process the signal acting on the touch key, it is necessary to perform analog-to-digital conversion on the analog voltage to obtain a digital signal. Therefore, the preprocessing may include analog-to-digital conversion.

[0032] The first touch signal may be, for example, a signal generated by different types of fluid interference sources acting on the touch key in a predetermined form, or a signal generated when the touch key is in an initial state, or a signal generated by manually touching the touch key when different types of fluid interference sources act on the touch key in different forms, or a signal generated by manually touching the touch key when the touch key is in an initial state. Exemplarily, different types of fluid interference sources may include interference sources of cold water, hot water, soap, foam, and the like. Exemplarily, different forms may include forms such as attachment, flow, or splashing.

[0033] The first number represents the number of the first touch signals. In this example, the first number is 6. In other examples, it can be any other feasible actual value, which is not limited here.

[0034] In step 102, in an exemplary embodiment, the first fitting curve may be formed as follows: The first fitting curve is obtained by subtracting a fitting curve formed according to the first number of first key values ​​from a fitting curve formed according to a group of key values ​​obtained according to the third type of signal.

[0035] Exemplarily, the fitting method used to form the fitting curve according to the key value may include, but is not limited to, linear fitting, polynomial fitting, exponential fitting, logarithmic fitting, etc., which are not limited here.

[0036] In an exemplary embodiment, the first fitting curve may be formed as follows: Determine a second number of second key values ​​according to the first number of first key values; The first fitting curve is obtained by subtracting a fitting curve formed according to the second number of second key values ​​from a fitting curve formed according to a group of key values ​​obtained according to the third type of signal.

[0037] In an exemplary embodiment, determining a second number of second key values ​​according to the first number of first key values ​​includes: dividing the first number of first key values ​​into a second number of groups; Each of the second number of groups includes a third number of first key values; An average value of the third number of first key values ​​is used as the second key value.

[0038] Assuming that 30 consecutive first key values ​​are obtained, 5 consecutive first key values ​​can be grouped into one group, and the average value of these 5 first key values ​​is taken as a second key value. The number of key values ​​contained in each group in the example here refers to the third number. In this example, the first number is 30, the second number is 6, and the third number is 5. The third number is the number of first key values ​​in each group after the first number of first key values ​​are grouped, so the third number can be smaller than the first number.

[0039] For example, the third number of first key values ​​may be averaged as follows: weighted averaging may be performed directly, that is, the third number of first key values ​​may be added up and divided by the third number to obtain the average value; or after removing the maximum value and the minimum value, the remaining first key values ​​may be added up and divided by the removed number to obtain the average value. Alternatively, other methods may be used to obtain the average value, which is not limited here.

[0040] In step 102, as described above, the first fitting curve is obtained by subtracting a fitting curve formed according to the first number of first key values ​​from a fitting curve formed according to the third type of signal, or by subtracting a fitting curve formed according to the second number of second key values ​​from a fitting curve formed according to the third type of signal. The subtraction of the fitting curve formed according to the second number of second key values ​​from a fitting curve formed according to the third type of signal may be performed in the following manner:

[0041] Assume that the expressions of two curves (for example, a fitting curve formed according to the second number of second key values ​​and a fitting curve formed according to a set of key values ​​obtained from the third type of signal) are respectively: and ,if and is a function, we can directly subtract it in the expression, that is, ;if and are data points, then subtract at each corresponding point. For example, for each Value, calculation Afterwards, you can A new curve is formed, which is the curve obtained by subtracting the two curves.

[0042] In step 102, the first type of signal, i.e., the signal generated by the non-human touch on the touch key, may include a signal generated by a predetermined type of fluid interference source acting on the touch key in a predetermined form. The predetermined type of fluid interference source may include interference sources of cold water, hot water, soap, foam, etc. Exemplarily, the predetermined form may include adhesion, flow, or splashing.

[0043] The second type of signal may include a signal generated by artificially touching the touch key when a predetermined type of fluid interference source acts on the touch key in a predetermined form.

[0044] In step 102, the initial state of the touch key may be the state of the electrical device each time it is powered on. Each time the device is powered on, it will enter the touch key parameter adaptation stage, at which time the touch chip continuously collects and pre-processes the signals generated in the initial state for each touch key according to the preset period, and obtains a set of key values ​​for each touch key in the initial state. A curve can be formed based on the set of key values, and the set of key values ​​and the formed curve are saved in the feature library. When not used for a long time, the touch chip will also scan all touch keys one by one, update the initial values ​​of the touch keys, and realize dynamic tracking.

[0045] In step 103, the method for calculating the similarity of the fitting curves adopts existing methods, such as the mean square error method, the Pearson correlation coefficient method, the mutual information method, the Frobenius norm method, etc. Among them, the mean square error method is to determine the similarity by calculating the average value of the sum of squares of the point-to-point errors between the two curves. The Pearson correlation coefficient method determines the similarity by measuring the linear correlation between the two curves. The mutual information method determines the similarity by measuring the dependence between the two curves. The Frobenius norm method determines the similarity by calculating the Frobenius norm of the difference matrix of the two curves at each point. Which specific similarity method is used is not limited here.

[0046] In an exemplary embodiment, determining the type of the first touch signal according to the relationship between the similarity and the similarity threshold may include: When the relationship between the similarity and the similarity threshold is that the similarity is greater than the similarity threshold, the type of the touch signal corresponding to the second fitting curve is used as the type of the first touch signal.

[0047] Exemplarily, the similarity threshold may be 90%, or may be set to other values ​​or intervals as required, such as greater than 70%.

[0048] Assuming that the type of the first type of signal is the first type, the type of the second type of signal is the second type, the type of the third type of signal is the third type, and the type of the touch signal corresponding to a second fitting curve in the feature library is the first type, then if the similarity between the first fitting curve and the second fitting curve is greater than the similarity threshold, then the type of the first touch signal is the first type. That is, the first touch signal belongs to the first type of signal.

[0049] In step 104, the corresponding switch element does not act, which means that the switch element maintains the original state.

[0050] In an exemplary embodiment, the control method of the switch element may further include: When it is determined that the first touch signal belongs to the second type of signal, the corresponding switch element is controlled to be turned on or the corresponding switch element is controlled according to the first number of first key values.

[0051] In an exemplary embodiment, controlling corresponding switch elements according to the first number of first key values ​​includes: Calculating a key value generated by manually touching the touch key according to an average value of the first number of first key values, and turning on the switch element when the key value generated by manually touching the touch key is greater than or equal to a first threshold; The first threshold is the minimum key value generated by manually touching the touch key.

[0052] In this embodiment, when it is confirmed that the first touch signal belongs to the second category of signals, the key value generated by manually touching the touch key is compared with the minimum key value generated by manually touching the touch key, so that the human touch can be reconfirmed to further avoid false triggering of the touch key, thereby further improving the reliability of the touch key.

[0053] In an exemplary embodiment, calculating the key value generated by manually touching the touch key according to the average value of the first number of first key values ​​includes: In the case where it is determined that the first touch signal is a signal generated by both non-human touching of the touch key and human touching of the touch key, a key value generated by human touching the touch key is obtained by subtracting a value obtained by collecting and preprocessing a signal generated by non-human touching of the touch key and a value obtained by collecting and preprocessing a signal generated by the touch key in an initial state from an average value of the first number of first key values; When it is determined that the first touch signal is a signal generated by manually touching the touch key when the touch key is in an initial state, the key value generated by manually touching the touch key is obtained by subtracting the value obtained by collecting and preprocessing the signal generated by the touch key in the initial state from the average value of the first number of first key values.

[0054] For example, the value obtained by collecting and preprocessing the signal generated when the touch key is in the initial state can be the average value of multiple values ​​collected continuously. When calculating the average value, the maximum and minimum values ​​can be removed and the remaining values ​​can be averaged, so that the initial value of the touch key obtained is more accurate.

[0055] It should be noted that the embodiment of the present application uses a curve for comparison in order to compare the dynamic process within a period of time. If the average value of the collected data is taken for comparison, it belongs to static value comparison. For the embodiment of the present application, the dynamic process can better reflect the actual situation when the key is touched, and can improve the reliability of the touch key compared with the static value comparison.

[0056] Figure 2 is a schematic diagram of a touch chip according to an embodiment of the present application, such as Figure 2 As shown, it includes a memory 100 and a processor 200, The memory 100 is used to store a program for controlling the switch element; The processor 200 is used to read a program for executing the switch element control and execute the method described in any one of the above embodiments.

[0057] Figure 3 is a schematic diagram of a shower device according to an embodiment of the present application, such as Figure 3 As shown, the shower comprises: a panel, at least one touch button, at least one switch element and the above-mentioned touch chip, and the touch button cooperates with the panel.

[0058] The shower may include a plurality of touch buttons, and different water discharge effects may be controlled by different touch buttons. For example, the plurality of touch buttons may include a hand-held shower touch button, a lower water discharge touch button, and a top spray water discharge touch button.

[0059] The shower may include a plurality of switch elements, which may be solenoid valves. The type and number of solenoid valves are not limited and may be set accordingly according to the function of the shower. For example, the battery valve may be a hand-held shower solenoid valve or a bottom water outlet solenoid valve or a top spray solenoid valve. Each solenoid valve is respectively arranged in the water path of each water outlet, and is used to open these water paths so that water can flow out of the corresponding components. For example, a hand-held shower solenoid valve is arranged in the water path of the water outlet of the hand-held shower. When the hand-held shower solenoid valve is opened, water flows out of the water outlet of the hand-held shower.

[0060] The hand-held showerhead touch button, the lower water outlet touch button, and the top spray water outlet touch button are used to control the opening and closing of the hand-held showerhead solenoid valve, the lower water outlet solenoid valve, and the top spray solenoid valve, respectively. Exemplarily, the touch button switch includes a spring, one end of the spring abuts against the panel, and the other end of the spring can be connected to the input end of the touch chip through a resistor, and the output end of the touch chip is connected to the solenoid valve.

[0061] In an exemplary embodiment, the shower is provided with a circuit board, on which pin solder joints of the touch chip and a solder pad of each touch button are provided; The wiring length and wiring width between the pin solder joint of the touch chip and each pad meet the preset first requirement; The spacing between adjacent touch key switches meets the preset second requirement; The wiring position on the circuit board meets the preset third requirement; The spacing between the traces on the circuit board and the electrical components on the circuit board meets a preset fourth requirement.

[0062] For example, the preset first requirement may be that the maximum length of the trace between the pin solder joint of the touch chip and each pad may be 200 mm, and the maximum trace width may be 0.3 mm. Because the trace is short, the spatial interference is small; if the trace is long, the electromagnetic waves in daily life will cause crosstalk to the trace, thereby forming clutter and causing the touch button to be triggered incorrectly.

[0063] The preset second requirement may be that the spacing between adjacent touch keys exceeds 1 mm to avoid mutual influence between adjacent touch keys. The influence here may mean that when one touch key is pressed, the adjacent touch keys will also have a large change, thereby causing false triggering of the adjacent touch keys.

[0064] The preset third requirement may be that the routing line is prohibited from being arranged under any touch button unless the routing line is connected to the touch button.

[0065] If the wiring is arranged under the touch button, the signal will fluctuate during the transmission process. There will be a spatial electromagnetic field around the fluctuating signal. The spring will generate a current signal when cutting the spatial electromagnetic field, which may cause false triggering of the touch button.

[0066] The preset fourth requirement may be that the safe distance between the touch button wiring and the metal parts of other electrical devices is greater than 5 mm, otherwise self-inductance capacitance will be generated between the spring of the touch button and the metal part, resulting in inaccurate detected capacitance value.

[0067] In an exemplary embodiment, the material of the panel is a glass material or a non-glass material with a dielectric constant within a preset range. Because for glass materials or non-glass materials with a dielectric constant within a preset range (dielectric constant can be 2.0-8.0), after a finger touches these insulating materials, the capacitance value will not change, and metal will absorb the capacitance signal between the capacitive sensor and the human body, resulting in decreased sensitivity and inability to correctly identify the finger touch signal, thereby affecting the switch control of the switch element. Therefore, the material of the panel cannot be a conductive material, and paint containing metal particles cannot be used on the panel.

[0068] The thickness of panels of different materials meets the preset fifth requirement.

[0069] For example, the preset fifth requirement may be that the maximum thickness of a panel made of non-glass material is less than 5 mm, and the thickness of a panel made of glass material is less than 8 mm. If the thickness of the panel is too large, the change in capacitance cannot be detected.

[0070] When the touch button is a spring-type inductive button, the distance between the spring button and the panel should be consistent, and there should be no gap between the top of the spring and the panel.

[0071] When the shower of the embodiment of the present application is in the standby state, the touch chip continuously collects the touch signal acting on a certain touch key according to the preset cycle, the touch chip in the circuit board assembly pre-processes the touch signal to obtain multiple key values, and compares the multiple key values ​​with each group of key values ​​in the feature library. If the comparison result is that the similarity with each group of key values ​​in the feature library is lower than the similarity threshold, it is determined that the touch signal is not generated by a fluid interference source such as cold water, hot water, soap, foam, etc. or is generated when the touch key is in the initial state, and then the average value of the multiple key values ​​is subtracted from the value obtained by collecting and pre-processing the signal generated by the predetermined type of fluid interference source acting on the touch key in a predetermined form to obtain the key value generated by artificially touching the touch key and the minimum threshold corresponding to the artificial touch situation, or the average value of the multiple key values ​​is subtracted from the value obtained by collecting and pre-processing the signal generated by the touch key when the touch key is in the initial state to obtain the key value generated by artificially touching the touch key and the minimum threshold corresponding to the artificial touch situation, if the comparison result is greater than or equal to, then the solenoid valve corresponding to the touch key is opened. Assuming that the touch key is a hand-held shower touch key, the hand-held shower solenoid valve is opened. By eliminating the interference sources of fluids such as cold water, hot water, soap, and foam from acting on the touch buttons, water can be prevented from accidentally touching the panel during showering, causing the water button to be accidentally triggered, thereby preventing the shower from accidentally discharging water. By eliminating the situation where the touch button is in the initial state, the initial state of the touch button can be avoided, causing the water button to be accidentally triggered, thereby preventing the shower from accidentally discharging water. It can also prevent the water button from being accidentally triggered by a slight human touch, thereby preventing the shower from accidentally discharging water.
