[0033] Embodiments of the present application are described below in detail with reference to the accompanying drawings, wherein the same or similar components or components having the same or similar functions are denoted by the same or similar reference numerals throughout the drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

[0034] The water treatment device and its water flow estimation method and device, and storage medium of the embodiments of the present application are described below with reference to the accompanying drawings.

[0035] Figure 1 is a flowchart of the water flow estimation method of the water treatment device in an embodiment of the present application.

[0036] As shown in Figure 1 The present application proposes a water flow estimation method of a water treatment device, wherein the water treatment device comprises a water pump, and the water flow estimation method comprises the following steps:

[0037] S10, obtaining operation data of the water treatment device.

[0038] Specifically, the operation data in the present embodiment can be experimental data or historical data, which can be directly obtained from the operation log of the water treatment device, wherein the operation data can include the input power of the water pump, the rotating speed of the water pump, and the water flow of the water treatment device under the control of the input power and the rotating speed.

[0039] S20, constructing a first preset model, a second preset model and a third preset model of the water treatment device under different environmental temperatures according to the operation data.

[0040] Specifically, after obtaining the operation data of the water treatment device, the corresponding model can be constructed according to the operation data, and it should be noted that the model in the present embodiment can be obtained by fitting two or more data. The present embodiment constructs multiple preset models, and it can be understood that the model related to the water flow can be fitted first, and then other parameters related to the water flow can be fitted to obtain other models. Moreover, since some operation data will change due to the influence of environmental temperature, the present embodiment also sets corresponding preset models for different environmental temperatures.

[0041] Specifically, the first preset model in the present embodiment can be obtained by fitting the input power of the water pump and the rotating speed of the water pump, the second preset model can be obtained by fitting the input power of the water pump and the water flow of the water treatment device, and the third preset model can be obtained by fitting the rotating speed of the water pump and the water flow of the water treatment device.

[0042] Further, the first preset model, the second preset model and the third preset model in the embodiment can be a group of models, and a group of models can be constructed every preset temperature step, where the preset temperature step can be 5 degrees Celsius. That is, every 5 degrees Celsius, one first preset model, one second preset model and one third preset model are constructed. For example, first preset models, second preset models and third preset models corresponding to 0 degrees Celsius, 5 degrees Celsius, 10 degrees Celsius, 15 degrees Celsius, 20 degrees Celsius, 25 degrees Celsius, 30 degrees Celsius, 35 degrees Celsius and 40 degrees Celsius can be constructed.

[0043] S30, acquiring the current input power, the current rotating speed and the current environment temperature of the water pump.

[0044] S40, determining the first current model, the second current model and the third current model of the water treatment equipment under the current environment temperature according to the current environment temperature, the first preset model, the second preset model and the third preset model.

[0045] S50, determining the equivalent rotating speed of the water pump and the first water flow of the water treatment equipment according to the current input power, the first current model and the second current model.

[0046] Specifically, in the embodiment, the current input power and the current rotating speed of the water pump are both parameters associated with the water flow, if there are other parameters associated with the water flow, and these parameters also participate in constructing the preset model, then these parameters also need to be acquired. In addition, since the preset model corresponding to different environment temperatures is not the same, the current environment temperature also needs to be acquired in the embodiment, and then the corresponding preset model is determined according to the current environment temperature, and the specific determination method will be described in detail in subsequent embodiments.

[0047] After the first current model, the second current model and the third current model corresponding to the current environment temperature are determined, the first water flow and the equivalent rotating speed of the water treatment equipment can be further calculated. Specifically, the first current model can represent the relationship between the input power and the rotating speed, the second current model can represent the relationship between the input power and the water flow, and the third current model can represent the relationship between the rotating speed and the water flow. The current input power is input into the first current model, and the rotating speed of the water pump can be obtained, which can be defined as the equivalent rotating speed. The current input power is input into the second current model, and the water flow of the water treatment equipment can be obtained, which needs to be combined with the water flow calculated in the subsequent step, so this water flow is defined as the first water flow.

[0048] S60, determining the second water flow of the water treatment equipment according to the equivalent rotating speed and the third current model.

[0049] Specifically, since the third current model is a model of the relationship between the rotating speed and the water outlet flow, the equivalent rotating speed obtained in the above step is input into the third current model, so as to obtain another water outlet flow of the water treatment device, which is different from the first water outlet flow, and the water outlet flow is defined as the second water outlet flow in the embodiment.

[0050] S70, estimating the actual water outlet flow of the water treatment device according to the first water outlet flow, the second water outlet flow, the equivalent rotating speed and the current rotating speed.

[0051] Specifically, in some embodiments, the average of the first water outlet flow and the second water outlet flow can also be directly used as the actual water outlet flow of the water treatment device, and the embodiment combines the equivalent rotating speed and the current rotating speed to participate in the calculation, so as to further improve the calculation accuracy of the actual water outlet flow.

[0052] In the embodiment, estimating the actual water outlet flow of the water treatment device according to the first water outlet flow, the second water outlet flow, the equivalent rotating speed and the current rotating speed includes: calculating a second correction coefficient according to the equivalent rotating speed and the current rotating speed; calculating an average water outlet flow of the first water outlet flow and the second water outlet flow; and estimating the actual water outlet flow of the water treatment device according to the second correction coefficient and the average water outlet flow.

[0053] Specifically, the embodiment first calculates the second correction coefficient through the equivalent rotating speed and the current rotating speed, and the second correction coefficient can be calculated through the formula q=(V-|V1-V|) / V, where q represents the second correction coefficient, V represents the current rotating speed, and V1 represents the equivalent rotating speed. After the second correction coefficient is calculated, the actual water outlet flow of the water treatment device can be calculated through the formula f=q*(fp1+fv1) / 2, where f represents the actual water outlet flow of the water treatment device, fp1 represents the first water outlet flow, and fv1 represents the second water outlet flow, and (fp1+fv1) / 2 represents the average water outlet flow. Further, in order to ensure the correction accuracy, the embodiment also limits the minimum value of the second correction coefficient, that is, the second correction coefficient is greater than or equal to a preset correction value, that is, if the calculated second correction coefficient is less than the preset correction value, the preset correction value is assigned to the second correction coefficient. Optionally, the preset correction value is 0.875.

[0054] In some embodiments of the present application, as shown in Figure 2 determining the first current model, the second current model and the third current model of the water treatment device under the current environment temperature according to the current environment temperature, the first preset model, the second preset model and the third preset model includes:

[0055] S201, determining adjacent first environment temperature and second environment temperature according to the current environment temperature.

[0056] S202, calculating a first correction coefficient according to the current environment temperature, the first environment temperature and the second environment temperature.

[0057] S203, determining a first current model according to the first correction coefficient, the first preset model corresponding to the first environment temperature and the first preset model corresponding to the second environment temperature, determining a second current model according to the first correction coefficient, the second preset model corresponding to the first environment temperature and the second preset model corresponding to the second environment temperature, and determining a third current model according to the first correction coefficient, the third preset model corresponding to the first environment temperature and the third preset model corresponding to the second environment temperature.

[0058] Specifically, first refer to Figure 3a 、 3b , 4a, 4b, 5a and 5b, wherein 3a represents the first preset model corresponding to the environment temperature of 10 degrees Celsius, 3b represents the first preset model corresponding to the environment temperature of 15 degrees Celsius, 4a represents the second preset model corresponding to the environment temperature of 10 degrees Celsius, 4b represents the second preset model corresponding to the environment temperature of 15 degrees Celsius, 5a represents the third preset model corresponding to the environment temperature of 10 degrees Celsius, and 5b represents the third preset model corresponding to the environment temperature of 15 degrees Celsius. If the current environment temperature is 12.5 degrees Celsius, then the adjacent first environment temperature can be determined as 10 degrees Celsius and the adjacent second environment temperature can be determined as 15 degrees Celsius according to the current environment temperature, and then the first correction coefficient can be calculated according to the current environment temperature, the first environment temperature and the second environment temperature, specifically by the formula a=(t1-t0) / (t2-t0), wherein a represents the first correction coefficient, t1 represents the current environment temperature, t0 represents the first environment temperature, and t2 represents the second environment temperature. After the first correction coefficient is calculated, the current model can be calculated by the formula f(t1)=a*f(t0)+(1-a)*f(t2), wherein f(t1) represents the current model corresponding to the current environment temperature, f(t0) represents the preset model corresponding to the first environment temperature, and f(t2) represents the preset model corresponding to the second environment temperature.

[0059] For example, the first preset model corresponding to 10 degrees Celsius is y=0.0349015084657x 2 +3.8512118551462x+471.4276095039620, and the first preset model corresponding to 15 degrees Celsius is y=0.0277430298727x 2+ 5.1795362614956x + 465.1329971422220, in the case of the current ambient temperature being 12.5 degrees Celsius, then the first correction coefficient a = (12.5-10) / (15-10) = 0.5, so the first current model y = 0.5*(0.0349015084657x 2 + 3.8512118551462x + 471.4276095039620) + (1-0.5)*(0.0277430298727x 2 + 5.1795362614956x + 465.1329971422220) = 0.031322269169x 2 + 4.515374058321x + 468.280303323092. If the current input power is obtained as 91 watts, and the current rotating speed is 1100 rpm, then the current input power belongs to the first current model, so the equivalent rotating speed is about equal to 1138 rpm, according to the current rotating speed and the equivalent rotating speed, a second correction coefficient q = (1100-|1138-1100|) / 1100 = 0.965 can be calculated, the second correction coefficient is greater than the preset correction value 0.875, so 0.965 can be directly used. In the above manner, the second current model corresponding to 12.5 degrees Celsius can be determined as y = 0.5*(-0.0000953395643x 2 + 0.0265722355093x + 0.8552144736188) + (1-0.5)*(-0.0000960626845x 2 + 0.0304727179025x + 0.89204241408350) = -0.0000957011244x 2 + 0.0285224767059x + 0.87362844385115. The first water flow fp1 is 2.67667 liters per minute when the current input power 91 watts is input into the second current model. In the above manner, the third current model corresponding to 12.5 degrees Celsius can be determined as y = 0.5*(-0.000001504922244x 2 + 0.004517729379317x - 0.672857944004267) + (1-0.5)*(-0.0000015530678x 2 + 0.0050933088121x - 0.9456855449207) = -0.000001528995022x 2+0.0048055190957085x-0.8092717444624835, the second water flow fv1 is 2.679293157183 liters per minute by inputting the equivalent speed 1138 into the third current model. According to the actual water flow calculation formula f=q*(fp1+fv1) / 2, the actual water flow f=0.965*(2.67667+2.679293157183) / 2=2.584252223341 liters per minute.

[0060] In conclusion, the water flow estimation method of the water treatment equipment in the embodiment of the present application can improve the detection accuracy of the water flow, without occupying additional space, reducing the detection cost, and improving the estimation range.
