[0079] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0080] It should be noted that, in this document, the terms "comprising", "including", or any other variant thereof are intended to cover a non-exclusive inclusion, such that processes, methods, articles, or apparatuses that comprise a list of elements are not limited to those elements, but can include other elements not expressly listed or inherent to such processes, methods, articles, or apparatuses. Without more limitations, the element defined by the statement "comprising a" does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0081] In the related art, the same component parameters are set for all home appliances of the same type, so that all home appliances of the same type can work normally within the same input voltage range. However, when multiple home appliances of the same type work in different regions, due to the different voltage fluctuation conditions of the power grids in each region, the multiple home appliances of the same type may have different failure conditions when used in the range of the power grids in different regions, resulting in low work reliability of the home appliances.

[0082] Based on the above problems, the present application proposes the following technical concept: in view of the different voltage fluctuation ranges of the power grids in each region, so that the home appliances working in each region can work normally without being affected by the voltage fluctuation of the power grid in the region. The home appliances in each region perform the following steps: first, obtain the working voltage information of multiple home appliances of the same type working in the same region within a historical period. Second, according to the obtained working voltage information of the multiple home appliances of the same type within the historical period, find out the highest voltage value and the longest duration of the lowest voltage value of the multiple devices in the region with the longest duration. Finally, according to the highest voltage value with the longest duration and the lowest voltage value with the longest duration, determine the component parameters for each component in the type of home appliances, so that the home appliances can work normally without being affected by the voltage fluctuation of the power grid in the region.

[0083] Next, the application will be described in detail in combination with Figure 1 The application scenario of the embodiments of the present application is introduced.

[0084] Figure 1 A schematic diagram of an application scenario provided by the embodiments of the present application is shown in FIG. 1. Please refer to Figure 1, including a first region and a server. Wherein the first region includes home appliance 1, home appliance 2, …, home appliance n. It should be noted that home appliance 1-n are all home appliances of a preset type. For example, home appliance 1-n are n identical washing machines. The server obtains working voltage information of home appliance 1, home appliance 2, …, home appliance n in a historical period. According to the working voltage information of each home appliance in the historical period, the minimum working voltage and the maximum working voltage of the home appliances of the preset type in the first region are determined. The server determines the component parameters corresponding to each component in the home appliances of the type according to the minimum working voltage and the maximum working voltage. Then, the components meeting the component parameters are used to produce the home appliances of the preset type, so that the home appliances of the preset type working in the first region can work normally without being affected by the voltage fluctuation of the power grid in the first region, which improves the reliability of the home appliances of the preset type working in the first region.

[0085] In the following, the technical solutions shown in the present application will be described in detail through specific embodiments. It should be noted that the following embodiments can exist independently or can be combined with each other. For the same or similar content, it will not be repeated in different embodiments.

[0086] Based on the technical concept introduced above, the determination method of the device parameters provided by the present application will be described in detail in combination with Figure 2 and specific embodiments, Figure 2 the flow of the determination method of the device parameters provided by the present application Figure 1 .

[0087] As Figure 2 indicated, the method comprises:

[0088] S201, obtaining working voltage information of a plurality of home appliances in a preset region in a historical period, the working voltage information comprising a plurality of voltage intervals and working time length of the home appliances in each voltage interval, and the types of the plurality of home appliances being a preset type.

[0089] The execution subject of the embodiments of the present application can be a server or a data processing device of a home appliance arranged in the server. Wherein the data processing device of the home appliance can be realized by the combination of software and / or hardware.

[0090] It should be noted that the preset region refers to a region composed of a plurality of regions with consistent power grid voltage fluctuation range.

[0091] The types of the plurality of home appliances are a preset type. It should be noted that the plurality of home appliances are devices of the same type. For example, the plurality of home appliances can be a plurality of identical washing machines, etc., which are not particularly limited.

[0092] The historical period is the time from the time of the home appliance leaving the factory to the current time, wherein the current time is the time corresponding to the acquisition of the working voltage information.

[0093] The working voltage information includes a plurality of voltage intervals and the working time length of the home appliance in each voltage interval. For example, the plurality of voltage intervals can be [110V, 120V), [120V, 130V), [130V, 140V), …, [360V, 370V), [370V, 380V). Wherein, the interval size of each voltage interval is the same, and the interval size of each voltage interval and the total voltage range included by the plurality of voltage intervals can be selected according to the needs, and no limitation is made to this. The working time length of each voltage interval is the cumulative length of time when the input voltage of the home appliance is in each voltage interval during the historical period. For example, the working time length of the current home appliance 1 in the voltage interval [200V, 210V) is 100 hours, the working time length in the voltage interval [210V, 220V) is 320 hours, and the working time length in the voltage interval [220V, 230V) is 120 hours. After that, the home appliance 1 continues to work for 1 hour, and the working voltage during the 1 hour is: the time length of the voltage continuously in the voltage interval [200V, 210V), [210V, 220V) and [220V, 230V) is respectively: 0.2 hours, 0.6 hours, 0.2 hours. Therefore, after working for 1 hour, the working voltage information of the home appliance 1 is updated to: the working time length of the current home appliance 1 in the voltage interval [200V, 210V) is 100.2 hours, the working time length in the voltage interval [210V, 220V) is 320.6 hours, and the working time length in the voltage interval [220V, 230V) is 120.2 hours. Wherein, the update frequency of the working voltage information of the home appliance, for example, can be updated every 5 minutes during the working of the home appliance, and the working voltage information is also updated once when the home appliance stops working. The update frequency and the update method are not particularly limited, and can be set according to the actual needs. For example, the working voltage information of the home appliance 1 in the historical period can be shown in Table 1:

[0094] Table 1

[0095]

[0096] It should be noted that Table 1 is only an example of working voltage information and is not a limitation of working voltage information.

[0097] For example, the server obtains the working voltage information of the household appliance 1 as shown in Table 1. The working voltage information of the household appliance 1 includes N voltage intervals, and the working time of the household appliance in the N voltage intervals is respectively: the working time of the household appliance 1 in the working interval 1 is the working time 1, the working time of the household appliance 1 in the working interval 2 is the working time 2, the working time of the household appliance 1 in the working interval 3 is the working time 3, and so on. It should be noted that the sum of the working time corresponding to the N voltage intervals is the total working time of the household appliance 1 after leaving the factory.

[0098] In S202, the minimum voltage and the maximum voltage are determined according to the working voltage information.

[0099] After the server obtains the working voltage information of each household appliance in the historical period based on the above step S201, the server determines the minimum voltage and the maximum voltage according to the working voltage information of each household appliance in the historical period.

[0100] It should be noted that each household appliance corresponds to a certain normal working voltage range, that is, if the voltage connected to the household appliance is within the normal working voltage range corresponding to the household appliance, the household appliance is in a normal working state; if the voltage connected to the household appliance is not within the normal working voltage range corresponding to the household appliance, the household appliance is in an abnormal working state, and the connected voltage will cause different degrees of damage to the components of the household appliance. For example, the normal working voltage range of the household appliance 1 can be [180V, 260V]. When the connected voltage of the household appliance 1 is 220V, it can be known that the connected voltage 220V is within the normal working voltage range [180V, 260V], so the working state of the household appliance 1 when the connected voltage is 220V is normal; when the connected voltage of the household appliance 1 is 150V, it can be known that the connected voltage 150V is not within the normal working voltage range [180V, 260V], so the working state of the household appliance 1 when the connected voltage is 150V is abnormal; or, when the connected voltage of the household appliance 1 is 280V, it can be known that the connected voltage 280V is not within the normal working voltage range [180V, 260V], so the working state of the household appliance 1 when the connected voltage is 280V is abnormal. It should be noted that when the household appliance is in an abnormal working state, the components in the household appliance will be damaged to different degrees.

[0101] Optionally, according to the normal working voltage range corresponding to the household appliance and the multiple voltage intervals of the working voltage information, multiple low-voltage intervals and multiple high-voltage intervals can be determined. The voltage in the low-voltage interval is less than or equal to the minimum voltage value of the normal working voltage range of the household appliance, and the voltage in the high-voltage interval is greater than or equal to the maximum voltage value of the normal working voltage range of the household appliance.

[0102] Next, a possible implementation of determining the multiple low voltage intervals and the multiple high voltage intervals is described by way of a specific example.

[0103] In this embodiment, the normal voltage ranges of the N home appliances are the same, and the multiple voltage intervals in the working voltage information of the N home appliances are the same.

[0104] For example, taking the normal working voltage range of the home appliances 1-N as [180V, 260V], and the multiple voltage intervals in the working voltage information of the home appliances 1-N as [100V, 120V), [120V, 140V), [140V, 160V), [160V, 180V), [180V-, 200V), [200V, 220V), [220V, 240V), [240V, 260V), [260V, 280V), [280V, 300V), [300V, 320V), [320V, 340V), [340V, 360V), [360V, 380V) as an example, a manner of determining the multiple low voltage intervals and the multiple high voltage intervals is described. According to the normal working voltage range of the home appliances 1-N being [180V, 260V], it can be known that the minimum voltage value and the maximum voltage value of the normal working voltage range of the home appliances are 180V and 260V respectively. Therefore, the voltage intervals in which the voltage is less than the minimum voltage value 160V are determined as the low voltage intervals, i.e., the multiple low voltage intervals are [100V, 120V), [120V, 140V), [140V, 160V), [160V, 180V) respectively; and the voltage intervals in which the voltage is greater than the maximum voltage value 180V are determined as the high voltage intervals, i.e., the multiple high voltage intervals are [260V, 280V), [280V, 300V), [300V, 320V), [320V, 340V), [340V, 360V), [360V, 380V) respectively.

[0105] Next, a possible implementation of determining the minimum voltage and the maximum voltage is described by way of an example.

[0106] In a possible implementation, according to the working time length corresponding to each voltage interval in the working voltage information of the home appliances 1-N, the total working time length corresponding to each of the multiple low voltage intervals and the multiple high voltage intervals is determined. Then, according to the total working time length corresponding to the multiple low voltage intervals, the minimum voltage is determined, and according to the total working time length corresponding to the multiple high voltage intervals, the maximum voltage is determined.

[0107] Optionally, the working time lengths of the same low-voltage intervals in the working voltage information of the N home appliances are added to obtain total working time lengths corresponding to the low-voltage intervals; similarly, the working time lengths of the same high-voltage intervals in the working voltage information of the N home appliances are added to obtain total working time lengths corresponding to the high-voltage intervals.

[0108] Optionally, according to the total working time lengths corresponding to the low-voltage intervals, a low-voltage interval corresponding to the maximum total working time length is determined as a first low-voltage interval; a minimum voltage in the first low-voltage interval is determined as the minimum voltage; correspondingly, according to the total working time lengths corresponding to the high-voltage intervals, a high-voltage interval corresponding to the maximum total working time length is determined as a first high-voltage interval; a maximum voltage in the first high-voltage interval is determined as the maximum voltage.

[0109] In the following, the possible implementation manners are described through specific examples.

[0110] For example, based on the above example of the multiple low-voltage intervals and the multiple high-voltage intervals, if the total working time lengths corresponding to the multiple low-voltage intervals [100V, 120V), [120V, 140V), [140V, 160V), [160V, 180V) are 2 hours, 5 hours, 9 hours and 20 hours respectively, therefore, among the multiple low-voltage intervals, the low-voltage interval corresponding to the maximum total working time length is [160V, 180V), that is, the first low-voltage interval is [160V, 180V); a minimum voltage 160V in the first voltage interval [160V, 180V) is determined as the minimum voltage. Similarly, if the total working time lengths corresponding to the multiple high-voltage intervals [260V, 280V), [280V, 300V), [300V, 320V), [320V, 340V), [340V, 360V), [360V, 380V) are 18 hours, 30 hours, 19 hours, 15 hours, 12 hours and 5 hours respectively, therefore, among the multiple high-voltage intervals, the high-voltage interval corresponding to the maximum total working time length is [280V, 300V), that is, the first high-voltage interval is [280V, 300V); a maximum voltage 300V in the first voltage interval [280V, 300V) is determined as the maximum voltage.

[0111] S203, determining the component parameter of the preset component in the home appliance of the preset type according to the minimum voltage and the maximum voltage.

[0112] The preset component is a component in the home appliance of the preset type that is greatly affected by the voltage size. For example, taking a washing machine as an example, the components in the washing machine that are greatly affected by the voltage size are a motor, a microprocessor and the like.

[0113] The size of the load in the DC brushless motor is fixed, and the size of the load determines the size of the rated power. The size of the power of the DC brushless motor is equal to the product of the voltage across the DC brushless motor and the current flowing through the DC brushless motor. In the case where the load is unchanged, i.e., the rated power is unchanged, the voltage across the DC brushless motor is reduced, and then the current flowing through the DC brushless motor is increased. When the current flowing through the DC brushless motor exceeds the maximum current that can be carried by the DC brushless motor, the DC brushless motor is burned out. Then, in order to prevent the DC brushless motor from being burned out in the case where the voltage is increased, the size of the current flowing through the DC brushless motor needs to be reduced, so that the size of the current flowing through the DC brushless motor does not exceed the maximum current that can be carried by the DC brushless motor, i.e., the DC brushless motor is guaranteed not to be burned out. Since the size of the current is determined by the rated power of the DC brushless motor and the voltage across the DC brushless motor, when the voltage across the DC brushless motor is increased, in order to prevent the DC brushless motor from being burned out due to the increased current, the size of the load of the motor can be appropriately reduced.

[0114] Based on the step S202, the minimum voltage and the maximum voltage corresponding to the preset type of the household appliance are determined. Next, a possible implementation manner of determining the component parameters of the preset components in the preset type of the household appliance according to the minimum voltage and the maximum voltage is described.

[0115] In a possible implementation manner, first, the preset components that are greatly affected by the voltage are determined. For example, when the voltage is too high or too low, the preset components that are easily damaged. Second, according to the characteristics of the preset components, the component parameters of the preset components are determined, so that the preset components in the preset type of the household appliance can normally work without being affected by the fluctuation of the voltage of the power grid in the preset area.

[0116] The method for determining the device parameters provided in the embodiments of the present application includes: obtaining working voltage information of a plurality of household appliances in a preset area in a historical period, the working voltage information including a plurality of voltage intervals and working time lengths of the household appliances in each voltage interval, and the types of the plurality of household appliances being preset types. The minimum voltage and the maximum voltage are determined according to the working voltage information. The component parameters of the preset components in the preset type of the household appliance are determined according to the minimum voltage and the maximum voltage. When the preset components in the preset type of the household appliance meet the respective component parameters, the preset type of the household appliance can normally work without being affected by the fluctuation of the voltage of the power grid in the preset area when working in the preset area, which improves the reliability of the preset type of the household appliance working in the preset area.

[0117] On the basis of the above embodiments, the method for determining the device parameters provided in the present application is further introduced in combination with a specific embodiment.Figure 3 The application is introduced, Figure 3 The device parameter determination method provided by the embodiment of the application Figure 2 .

[0118] As Figure 3 shown, the method comprises:

[0119] S301, obtaining working voltage information of a plurality of home appliances in a preset region in a historical period, the working voltage information comprising a plurality of voltage intervals and working time length of the home appliances in each voltage interval, and the types of the plurality of home appliances being a preset type.

[0120] The specific implementation of step S301 is similar to that of step S201, and thus will not be described here.

[0121] S302, determining a plurality of low-voltage intervals in the plurality of voltage intervals, the voltage in the low-voltage interval being less than or equal to a first preset voltage.

[0122] It should be noted that the home appliances of the preset type correspond to a certain normal working voltage range.

[0123] The first preset voltage can be the minimum voltage value corresponding to the normal working voltage range.

[0124] A possible implementation of determining a plurality of low-voltage intervals in a plurality of voltage intervals will be described by way of example.

[0125] In one possible implementation, in the plurality of voltage intervals, the voltage interval in which the voltage is less than or equal to the first preset voltage is determined as a low-voltage interval, i.e., a plurality of low-voltage intervals are obtained.

[0126] Next, the above possible implementation will be described by way of example.

[0127] For example, the plurality of voltage intervals in the working voltage information of the home appliances of the preset type are [100V, 120V), [120V, 140V),..., [340V, 360V), [360V, 380V), and the normal working voltage range corresponding to the home appliances of the preset type can be [180V, 260V). Therefore, according to the normal working voltage range [180V, 260V), it can be known that the first preset voltage is 180V. Therefore, the plurality of low-voltage intervals in which the voltage is less than or equal to 180V are [100V, 120V), [120V, 140V), [140V, 160V), [160V, 180V).

[0128] S303, determine a plurality of high-voltage intervals in the plurality of voltage intervals, a voltage in the high-voltage interval being greater than or equal to a second preset voltage, the second preset voltage being greater than the first preset voltage.

[0129] The second preset voltage can be a maximum voltage value corresponding to the normal working voltage range.

[0130] Next, a possible implementation of determining a plurality of high-voltage intervals in a plurality of voltage intervals will be exemplarily described.

[0131] In a possible implementation, in the plurality of voltage intervals, a voltage interval in which the voltage in the interval is greater than or equal to the second preset voltage is determined as a high-voltage interval, that is, a plurality of high-voltage intervals are obtained.

[0132] Next, the above possible implementation will be described through a specific example.

[0133] For example, the working voltage information of the preset type of household appliance has a plurality of voltage intervals, respectively: [100V, 120V), [120V, 140V),..., [340V, 360V), [360V, 380V), and the normal working voltage range corresponding to the preset type of household appliance can be: [180V, 260V). Therefore, according to the normal working voltage range [180V, 260V), it can be known that the second preset voltage is 260V. Therefore, the plurality of high-voltage intervals in which the voltage in the interval is greater than or equal to 260V are: [260V, 280V), [280V, 300V), [300V, 320V), [320V, 340V), [340V, 360V), [360V, 380V).

[0134] S304, determine a total working duration corresponding to each low-voltage interval according to the working duration of each household appliance in each low-voltage interval.

[0135] Since the working duration of each household appliance in each voltage interval is only counted when the household appliance is working, the working voltage information of a single household appliance cannot fully reflect the fluctuation of the power grid voltage in the preset area. In order to comprehensively and accurately record the working duration of the preset area in each voltage interval, the working voltage information of a plurality of household appliances is used to determine the total working duration of the preset type of household appliance in each voltage interval in the preset area.

[0136] Next, a possible implementation of determining a total working duration corresponding to each low-voltage interval will be exemplarily described.

[0137] In a possible implementation, the working durations of each household appliance in the same low-voltage interval are summed, that is, the sum of the working durations obtained after the summing operation is the total working duration corresponding to each low-voltage interval.

[0138] The above possible implementation manners are described below by specific examples in combination with Table 2.

[0139] For the convenience of description, the present example is described by taking 3 home appliances as an example. It should be noted that the more the number of home appliances is, the better in actual implementation of the present scheme. For example, the 3 home appliances are home appliance 1, home appliance 2 and home appliance 3. The working time length of the 3 home appliances in each low-voltage interval can be shown in Table 2, wherein h is used to indicate the time length unit is hour (h):

[0140] Table 2

[0141]

[0142] According to the working time length of each home appliance in each low-voltage interval, the total working time length of each low-voltage interval is calculated. Specifically, the total working time length of the low-voltage interval [100V, 120V) is T1=11.3+16.3+13.3=40.9h; the total working time length of the low-voltage interval [120V, 140V) is T2=13.5+19.5+15.1=48.2h; the total working time length of the low-voltage interval [140V, 160V) is T3=20.5+30.1+20.6=71.2h; and the total working time length of the low-voltage interval [160V, 180V) is T4=18.9+19.3+21.1=59.3h.

[0143] S305, determining the low-voltage interval with the longest total working time length as the target low-voltage interval.

[0144] Based on the determination of the total working time length of each low-voltage interval in step S304, the target low-voltage interval is determined among the low-voltage intervals.

[0145] In one possible implementation manner, the low-voltage interval with the longest total working time length is determined as the target low-voltage interval. For example, the target low-voltage interval is determined based on the example corresponding to Table 2. According to the description in step S304, the total working time lengths corresponding to the low-voltage intervals [100V, 120V), [120V, 140V), [140V, 160V) and [160V, 180V) are 40.9h, 48.2h, 71.2h and 59.3h respectively. Therefore, the low-voltage interval corresponding to [140V, 160V) has the longest total working time length, and thus the low-voltage interval [140V, 160V) is determined as the target low-voltage interval.

[0146] S306, judging whether the total working time length corresponding to the target low-voltage interval is greater than or equal to a first preset time length, if yes, performing S307, if not, performing S308.

[0147] In this embodiment, the minimum voltage is determined by judging the size relationship between the total working time corresponding to the target low-voltage interval and the first preset time length.

[0148] S307, if yes, the minimum value of the target low-voltage interval is determined as the minimum voltage.

[0149] In this embodiment, when the total working time corresponding to the target low-voltage interval is greater than or equal to the first preset time length, the minimum voltage value of the target low-voltage interval is determined as the minimum voltage.

[0150] For example, the total working time corresponding to the target low-voltage interval [140V, 160V) is 71.2h, and the first preset time length is assumed to be 50h. It can be known that the total working time corresponding to the target low-voltage interval [140V, 160V) is greater than or equal to the first preset time length, and therefore the minimum voltage value 140V of the target low-voltage interval [140V, 160V) is determined as the minimum voltage.

[0151] S308, if no, the first preset voltage is determined as the minimum voltage.

[0152] In this embodiment, when the total working time corresponding to the target low-voltage interval is less than the first preset time length, the first preset voltage is determined as the minimum voltage.

[0153] For example, the total working time corresponding to the target low-voltage interval [140V, 160V) is 71.2h, and the first preset time length is assumed to be 80h. It can be known that the total working time corresponding to the target low-voltage interval [140V, 160V) is less than the first preset time length, and therefore the first preset voltage is determined as the minimum voltage. Referring to the example in step S302, for example, the first preset voltage is 180V. Therefore, the minimum voltage is 180V.

[0154] S309, according to the working time of each household appliance in each high-voltage interval, the total working time corresponding to each high-voltage interval is determined.

[0155] In a possible implementation, the working time of each household appliance in the same high-voltage interval is summed, that is, the sum of the working time obtained after the summing operation is the total working time corresponding to each high-voltage interval.

[0156] Next, the above possible implementation is described by a specific example in combination with Table 3.

[0157] For the convenience of description, the example takes three home appliances as an example for illustration. It should be noted that the more the number of home appliances is, the better in actual implementation of the scheme. For example, the three home appliances are home appliance 1, home appliance 2 and home appliance 3. The working time length of the three home appliances in each high-voltage interval can be shown in Table 3, wherein h is used to indicate the time length unit is hour (h):

[0158] Table 3

[0159]

[0160] According to the working time length of each home appliance in each high-voltage interval corresponding to Table 3, the total working time length of each high-voltage interval is calculated. For example, the total working time length of the high-voltage interval [260V, 280V) is: T5 = 10 + 9.5 + 11 = 30.5h. Similarly, the total working time lengths corresponding to the high-voltage intervals [280V, 300V), [300V, 320V), [320V, 340V), [340V, 360V), [360V, 380V) are 31.3h, 55.8h, 37.8h, 11.8h, 4h respectively.

[0161] S310, determining the high-voltage interval with the longest total working time length as the target high-voltage interval.

[0162] Based on the determination of the total working time length of each high-voltage interval in step S309, the target high-voltage interval is determined in each high-voltage interval.

[0163] In one possible implementation, the high-voltage interval with the longest total working time length is determined as the target high-voltage interval. For example, the target high-voltage interval is determined based on the example corresponding to Table 3. According to the description in step S309, the total working time lengths corresponding to the high-voltage intervals [260V, 280V), [280V, 300V), [300V, 320V), [320V, 340V), [340V, 360V), [360V, 380V) are 31.3h, 55.8h, 37.8h, 11.8h, 4h respectively. Therefore, the total working time length corresponding to the high-voltage interval [280V, 300V) is the longest, and therefore the high-voltage interval [280V, 300V) is determined as the target high-voltage interval.

[0164] S311, judging whether the total working time length corresponding to the target high-voltage interval is greater than or equal to the second preset time length, if yes, executing S312, if not, executing S313.

[0165] In this embodiment, the maximum voltage is determined by judging the size relationship between the total working time length corresponding to the target high-voltage interval and the second preset time length.

[0166] S312, if yes, determining the maximum voltage of the target high-voltage interval as the maximum voltage.

[0167] In this embodiment, when the total working time length corresponding to the target high-voltage interval is greater than or equal to the second preset time length, the maximum voltage value of the target high-voltage interval is determined as the maximum voltage.

[0168] For example, the total working time length corresponding to the target high-voltage interval [280V, 300V) is 55.8h, and the second preset time length is assumed to be 50h. It can be known that the total working time length corresponding to the target high-voltage interval [280V, 300V) is greater than or equal to the second preset time length, and therefore the maximum voltage value 330V of the target high-voltage interval [280V, 300V) is determined as the maximum voltage.

[0169] S313, if no, determining the second preset voltage as the maximum voltage.

[0170] In this embodiment, when the total working time length corresponding to the target high-voltage interval is greater than the second preset time length, the second preset voltage is determined as the maximum voltage.

[0171] For example, the total working time length corresponding to the target high-voltage interval [280V, 300V) is 55.8h, and the second preset time length is assumed to be 70h. It can be known that the total working time length corresponding to the target high-voltage interval [280V, 300V) is greater than the second preset time length, and therefore the second preset voltage is determined as the maximum voltage. Referring to the example in step S303, for example, the second preset voltage is 260V. Therefore, the maximum voltage is 260V.

[0172] S314, determining the component parameter of the preset component in the preset type of household appliance according to the minimum voltage and the maximum voltage.

[0173] The specific implementation of step S314 is similar to that of step S203, and will not be described here.

[0174] The method for determining device parameters provided in the embodiments of the present application determines the total working time length corresponding to each low-voltage interval according to the working time length of each low-voltage interval of each household appliance, and determines the total working time length corresponding to each high-voltage interval according to the working time length of each high-voltage interval of each household appliance. Further, the low-voltage interval with the longest total working time length is determined as a target low-voltage interval. It is judged whether the total working time length corresponding to the target low-voltage interval is greater than or equal to a first preset time length. If yes, the minimum value of the target low-voltage interval is determined as the minimum voltage. If no, the first preset voltage is determined as the minimum voltage. Further, the high-voltage interval with the longest total working time length is determined as a target high-voltage interval. It is judged whether the total working time length corresponding to the target high-voltage interval is greater than or equal to a second preset time length. If yes, the maximum value of the target high-voltage interval is determined as the maximum voltage. If no, the second preset voltage is determined as the maximum voltage. The minimum voltage is determined by judging the size relationship between the total working time length corresponding to the target low-voltage interval and the first preset time length. The maximum voltage is determined by judging the size relationship between the total working time length corresponding to the target high-voltage interval and the second preset time length. The component parameters of the preset component in the household appliance of the preset type are determined according to the minimum voltage and the maximum voltage.

[0175] On the basis of the above embodiments, the method for determining device parameters provided in the present application will be further introduced in combination with a specific embodiment. Figure 4 will be introduced, Figure 4 the flow of the method for determining device parameters provided in the embodiments of the present application Figure 3 .

[0176] As Figure 4 shown, the method comprises:

[0177] S401, obtaining working voltage information of a plurality of household appliances in a preset region in a historical period, the working voltage information comprising a plurality of voltage intervals and working time lengths of the household appliances in each voltage interval, and the types of the plurality of household appliances being a preset type.

[0178] The specific implementation of step S401 is similar to that of step S201, which will not be repeated here.

[0179] S402, determining a plurality of low-voltage intervals in the plurality of voltage intervals, the voltage in the low-voltage interval being less than or equal to a first preset voltage.

[0180] The specific implementation of step S402 is similar to that of step S302, which will not be repeated here.

[0181] S403, determining a plurality of high-voltage intervals in the plurality of voltage intervals, the voltage in the high-voltage interval being greater than or equal to a second preset voltage, and the second preset voltage being greater than the first preset voltage.

[0182] The step S403 has a similar implementation as the step S303, and thus no further description is provided herein.

[0183] S404, determining a total working time length corresponding to each low-voltage interval according to the working time length of each household appliance in each low-voltage interval.

[0184] The step S404 has a similar implementation as the step S304, and thus no further description is provided herein.

[0185] S405, determining whether there is at least one first low-voltage interval in the plurality of low-voltage intervals according to the total working time length corresponding to each low-voltage interval, the total working time length of the first low-voltage interval being greater than or equal to a first preset time length.

[0186] The first low-voltage interval is a low-voltage interval corresponding to a total working time length greater than or equal to the first preset time length in the plurality of low-voltage intervals.

[0187] In the embodiment, the value of the minimum voltage is further determined by determining whether there is at least one first low-voltage interval in the plurality of low-voltage intervals.

[0188] S406, if yes, determining a low-voltage interval with the minimum voltage in the at least one first low-voltage interval as a target low-voltage interval, and determining the minimum value of the target low-voltage interval as the minimum voltage.

[0189] In a possible implementation, when there is at least one first low-voltage interval in the plurality of low-voltage intervals, a low-voltage interval with the minimum voltage in the at least one first low-voltage interval is determined as a target low-voltage interval, and the minimum value of the target low-voltage interval is determined as the minimum voltage.

[0190] In the following, the possible implementation is described through a specific example.

[0191] For example, based on the example in the step S305 in the previous embodiment, it is known that the total working time lengths corresponding to the low-voltage intervals [100V, 120V), [120V, 140V), [140V, 160V), and [160V, 180V) are 40.9h, 48.2h, 71.2h, and 59.3h respectively, and the first preset time length is assumed to be 50h.

[0192] Therefore, the low-voltage intervals with the total working time lengths greater than the first preset time length in the plurality of low-voltage intervals are [140V, 160V) and [160V, 180V), i.e., the two first low-voltage intervals are [140V, 160V) and [160V, 180V).

[0193] Among the two first low-voltage intervals, the interval with the lowest voltage [140V, 160V) is determined as the target low-voltage interval, and the minimum value of the target low-voltage interval, 140V, is determined as the minimum voltage.

[0194] S407. If not, then the first preset voltage is set as the minimum voltage.

[0195] In one possible implementation, when there is no first low-voltage interval among the multiple low-voltage intervals, the first preset voltage is determined as the minimum voltage.

[0196] The following examples illustrate the possible implementation methods described above.

[0197] For example, based on the example in step S305 of the previous embodiment, it can be seen that the total working time corresponding to the low voltage ranges [100V, 120V), [120V, 140V), [140V, 160V) and [160V, 180V) are 40.9h, 48.2h, 71.2h and 59.3h respectively, and it is assumed that the first preset time is 80h.

[0198] Since the total operating time of the four low-voltage zones is less than the first preset time, there is no first low-voltage zone.

[0199] Next, the first preset voltage is set as the minimum voltage. Referring to step S302, the first preset voltage is 180V. Therefore, the minimum voltage is set to 180V.

[0200] It should be noted that the method for determining the minimum voltage can be achieved through steps S405-S407, or through steps S305-S308 in the previous embodiment.

[0201] S408. Determine the total working time for each high-voltage zone based on the working time of each household appliance in each high-voltage zone.

[0202] The specific implementation methods of steps S408 and S309 are similar, and will not be described in detail here.

[0203] S409. Based on the total working time corresponding to each high-voltage section, determine whether there is at least one first high-voltage section among the multiple high-voltage sections, and the total working time of the first high-voltage section is greater than or equal to the second preset time.

[0204] The second high-voltage zone is the high-voltage zone among multiple high-voltage zones whose total working time is greater than or equal to the second preset time.

[0205] In this embodiment, the value of the maximum voltage is further determined by determining whether there is at least one second high-voltage interval among multiple high-voltage intervals.

[0206] S410, if yes, determining, as a target high-voltage interval, an interval with the maximum voltage among at least one first high-voltage interval, and determining, as the maximum voltage, the maximum value of the target high-voltage interval.

[0207] In a possible implementation, when there is at least one second high-voltage interval in the plurality of high-voltage intervals, an interval with the maximum voltage among at least one second low-voltage interval is determined as a target high-voltage interval, and the maximum value of the target high-voltage interval is determined as the maximum voltage.

[0208] Next, the above possible implementation is described through a specific example.

[0209] For example, based on the example in step S309 in the last embodiment, it is known that the total working time lengths of the high-voltage intervals [280V, 300V), [300V, 320V), [320V, 340V), [340V, 360V), [360V, 380V) are 30.5h, 31.3h, 55.8h, 37.8h, 11.8h, 4h respectively, and it is assumed that the second preset time length is 35h.

[0210] Therefore, the high-voltage intervals with the total working time lengths greater than the second preset time length in the plurality of high-voltage intervals are [320V, 340V) and [340V, 360V), that is, the two first high-voltage intervals are [320V, 340V) and [340V, 360V) respectively.

[0211] In the two first high-voltage intervals [320V, 340V) and [340V, 360V), the interval with the maximum voltage [340V, 360V) is determined as a target high-voltage interval, and the maximum value 360V of the target high-voltage interval [340V, 360V) is determined as the maximum voltage.

[0212] S411, if no, determining the second preset voltage as the maximum voltage.

[0213] In a possible implementation, when there is no at least one first high-voltage interval in the plurality of high-voltage intervals, the second preset voltage is determined as the maximum voltage.

[0214] Next, the above possible implementation is described through a specific example.

[0215] For example, based on the example in step S309 in the last embodiment, it is known that the total working time lengths of the high-voltage intervals [280V, 300V), [300V, 320V), [320V, 340V), [340V, 360V), [360V, 380V) are 30.5h, 31.3h, 55.8h, 37.8h, 11.8h, 4h respectively, and it is assumed that the second preset time length is 60h.

[0216] Since the total working time length of the two high-voltage intervals is less than the second preset time length, there is no first high-voltage interval.

[0217] Next, the second preset voltage is determined as the maximum voltage. Referring to the second preset voltage being 260V in step S303. Therefore, the maximum voltage is determined as 260V.

[0218] It should be noted that the implementation method of determining the maximum voltage can be through steps S409-S411, or through steps S310-S313 in the previous embodiment.

[0219] S412, determining the component parameter of the preset component in the preset type of household appliance according to the minimum voltage and the maximum voltage.

[0220] Wherein, the specific implementation of step S412 is similar to that of step S203, which will not be repeated here.

[0221] The device parameter determination method provided by the embodiment of the application comprises the following steps: determining a total working time length corresponding to each low-voltage interval according to a working time length of each household appliance in each low-voltage interval, and determining a total working time length corresponding to each high-voltage interval according to a working time length of each household appliance in each high-voltage interval. According to the total working time length corresponding to each low-voltage interval, it is judged whether there is at least one first low-voltage interval in the plurality of low-voltage intervals, and the total working time length of the first low-voltage interval is greater than or equal to a first preset time length; if yes, the interval with the minimum voltage in the at least one first low-voltage interval is determined as a target low-voltage interval, and the minimum value of the target low-voltage interval is determined as the minimum voltage; if not, the first preset voltage is determined as the minimum voltage. According to the total working time length corresponding to each high-voltage interval, it is judged whether there is at least one first high-voltage interval in the plurality of high-voltage intervals, and the total working time length of the first high-voltage interval is greater than or equal to a second preset time length; if yes, the interval with the maximum voltage in the at least one first high-voltage interval is determined as a target high-voltage interval, and the maximum value of the target high-voltage interval is determined as the maximum voltage; if not, the second preset voltage is determined as the maximum voltage. According to the minimum voltage and the maximum voltage, the component parameter of the preset component in the preset type of household appliance is determined. According to the minimum voltage and the maximum voltage, the component parameter of the preset component in the preset type of household appliance is determined.
