[0019] See also Figure 1 and Figure 3 The present invention provides a household energy-saving housekeeper automatic control system, including a cloud server 1, a plurality of smart home devices 2 and a smart meter 3. The smart meter 3 is connected to the smart home devices 2 and the cloud server 1 in communication, and is mainly used to collect information of the plurality of smart home devices 2 and to perform intelligent control on the smart home devices 2. It undertakes the tasks of collecting, measuring and transmitting the original electric energy data, and also has the function of control, which is the basis for realizing information integration, analysis optimization and information display. In detail, in the present household energy-saving housekeeper automatic control system, in order to ensure that the power consumption of the smart home device 2 during daily use does not exceed the preset power consumption and thus achieve the purpose of energy saving, the smart meter 3 is built with a power detection module 301 for measuring the power consumption information, and the power consumption information mainly includes the actual power consumption and power consumption time generated by multiple smart home devices 2, so the power detection module 301 can measure the actual power consumption in different time periods, such as the power consumption. It can not only measure the power consumption, but also measure the power consumption in each time period, such as the power consumption per hour, so that it is convenient for the cloud server 1 to analyze the power consumption of different smart home devices 2 every hour, and then allocate the opening time of these smart home devices 2 according to these power consumption conditions to meet the preset power consumption requirements. Further, the power detection module 301 is a metering socket or a metering switch, and the metering socket and the metering switch can be used to electrically connect to the smart home device 2 and collect the power consumption information of the smart home device 2. Next, when the controller 302 collects the first power usage information collected by the power detection module 301 within the first time period, it will be sent to the cloud server 1. The cloud server 1 generates a control signal based on the first power usage information sent by the smart meter 3 and combined with a preset power usage. The cloud server 1 sends the control signal to the controller 302 of the smart meter 3. The controller 302 changes the power supply time of the smart meter 3 in the second time period according to the control signal, and the first time period is the same as the second time period. Among them, the second time period is after the first time period, and the second time period is the same as the second time period. For example, the first time period is 30 consecutive days, then the second time period is 30 days starting from the 31st day after the end of the first time period. That is to say, the cloud server 1 will plan the power consumption of multiple smart home devices 2 in the next time period for the user according to the power consumption of different smart home devices 2 in different time periods in the first time period, and in combination with the preset power consumption, such as changing the start-up time and start-up duration of each smart home device 2 in the second time period, so as to achieve the purpose of changing the power supply time of the smart meter 3 in the second time period, that is, the power supply time includes the start-up time and the start-up duration of the smart home device 2. Of course, the premise of the change is that an actual power consumption in the power consumption information exceeds the preset power consumption. If the actual power consumption does not exceed the preset power consumption, the power supply time of the smart meter 3 in the second time period is the same as the power supply time in the first time period, that is, the power supply time of the smart meter 3 in the first time period is maintained in the second time period. In addition, assuming that an actual power consumption in the power consumption information exceeds the preset power consumption, the control signal has the arrangement information of the start time and the start time of different smart home devices 2 in the next time period. Through such arrangement information, the power supply time of the smart meter 3 can be reduced, so that the actual power consumption in the second time period does not exceed the preset power consumption. For example, if the smart meter provides power to the smart home device for the power supply time of an initial duration in the first time period, since the actual power consumption exceeds the preset power consumption at this time, the power supply time of the smart meter in the second time period can be reduced to less than the initial duration, thereby reducing the actual power consumption. Furthermore, the first time period and the second time period can be one week or one month, which can be determined according to the needs of the user.Preferably, as an optional method, assuming that the current user Mr. Wang's electricity consumption in this month, i.e., the first time period, is 600 degrees, and he hopes to reduce it to 550 degrees in the next month, i.e., the second time period, that is, the preset electricity consumption is 550 degrees. Then, assuming that the smart home device 2 in the first time period, such as the water heater, is turned on 24 hours a day, its daily electricity consumption is 2 degrees, about 60 degrees a month. Since it is summer now, hot water is not needed all the time, so in the second time period, the cloud server 1 will combine the use time of the water heater in the first time period, and mark the time period with the longest average use time in the first time period. Then, in the second time period, except for the marked time period, the smart meter 3 will usually turn off the water heater, which is equivalent to reducing the power supply time of the smart meter 3, so as to achieve the purpose of saving electricity. If the opening time of the water heater is saved by half in the second time period, it is equivalent to saving about 30 degrees of electricity at this time, and the electricity consumption is saved by 30 degrees in the water heater. Similarly, the above method can also be used in other smart home devices 2, by marking the time periods with the longest average daily usage time of these smart home devices 2 in the first time period, so as to shut down the smart home devices 2 in other time periods in the second time period to save electricity, and easily achieve the goal of reducing electricity consumption to 550 degrees in the second time period.

[0020] As a preferred embodiment, when the actual power consumption exceeds the preset power consumption, the cloud server 1 calculates a power consumption difference between the actual power consumption and the preset power consumption, obtains a power consumption adjustment ratio through the power consumption difference, and the cloud server 1 sends the control signal with the power consumption adjustment ratio to the controller 302, and the controller 302 reduces the power supply time of the smart meter 3 in the second time period to be less than the initial duration according to the power consumption adjustment ratio in the control signal. For example, assuming that the actual power consumption in the first time period is 500 degrees, and the preset power consumption is 400 degrees, the power consumption difference between the actual power consumption and the preset power consumption is 100 degrees, and a power consumption adjustment ratio is obtained through the power consumption difference, and the power consumption adjustment ratio is 100 / 400*100%=25%, that is, in the next second time period, the smart meter 3 needs to reduce the power supply time by 25% based on the power supply time of the first time period. Assuming that the power supply time of the smart meter 3 to the water heater is 10 hours in the first time period, the power supply time of the smart meter 3 to the water heater will be shortened to 7.5 hours in the second time period. In this way, the power supply time of the smart meter 3 in the second time period is reduced to less than the initial time length, so that the total power consumption in the second time period does not exceed the preset power consumption.

[0021] Further, see Figure 2 The household energy-saving housekeeper automatic control system also includes a mobile terminal 4, which is communicatively connected to the smart meter 3. More specifically, the mobile terminal 4 is communicatively connected to the controller 302. The mobile terminal 4 can be a mobile phone, a tablet or a laptop, etc. Through these mobile terminals 4, these smart home devices 2 can be controlled, which is convenient for users to use and has a high degree of intelligence.

[0022] Furthermore, in order to ensure the safety of the user when using the smart home device 2, the smart meter 3 is used to shut down the smart home device 2 and issue a prompt message when the current flowing through the smart home device 2 is too large. The prompt message can be a buzzer or some prompting text content such as "The current working state is abnormal, please check manually" or other forms of content.

[0023] In addition, in order to achieve communication connection between the smart home device 2 and the smart meter 3, the smart home device 2 and the smart meter 3 are communicated through a WiFi module or a Bluetooth module.

[0024] To sum up, the smart meter 3 collects the user's electricity consumption information for different smart home devices 2 in different time periods and uploads it to the cloud server 1, so that the cloud server 1 can reasonably plan the start time of different smart home devices 2 according to the user's usage habits, so that the actual power consumption does not exceed a preset power consumption, and the working state of the smart home device 2 is well optimized. While meeting the user's life needs, it can reduce electricity bills and achieve energy conservation and emission reduction. Example 2

[0025] See also Figure 1 and Figure 2 In addition to planning and controlling electricity consumption, the present invention can also plan electricity charges, thereby achieving the purpose of saving electricity charges. At present, the electricity prices implemented in most areas of my country are not fixed, but peak and valley electricity prices or time-of-use electricity prices, that is, the electricity prices in different periods of the day are not the same. Therefore, it is necessary to collect the user's electricity consumption information for multiple smart home devices 2 in different time periods, and it is also necessary to collect electricity price information in different time periods, and upload these electricity consumption information and electricity price information to the cloud server 1 for analysis, so that the work of some smart home devices 2 can be completed in the time period of low electricity prices, and the number and working time of smart home devices 2 working in the time period of high electricity prices can be reduced, thereby achieving the purpose of saving electricity charges.

[0026] In detail, when planning electricity bills, the household energy-saving housekeeper automatic control system includes a cloud server 1, multiple smart home devices 2 and a smart meter 3. In this embodiment, the function of the smart meter 3 is mainly to control the smart home device 2 to work in different power supply time periods. The smart meter 3 is communicated with the smart home device 2 and the cloud server 1. The smart meter 3 supplies power to the smart home device 2 in a first power supply time period corresponding to a first electricity price within a first time period. The smart meter 3 includes a controller 302 and a power detection module 301. The power detection module 301 is communicated with the controller 302. The power detection module 301 is used to collect power usage information of multiple smart home devices 2. The controller 302 collects the power usage information and sends it to the cloud server 1. The cloud server 1 generates a first electricity fee according to the electricity usage information and the first electricity price, and generates a control signal after combining an electricity fee threshold. The cloud server 1 sends the control signal to the controller 302 of the smart meter 3. When the first electricity fee exceeds the electricity fee threshold, the smart meter 3 supplies power to the smart home device 2 in a second power supply period corresponding to the second electricity price in a second time period according to the control signal, and the second electricity price is lower than the first electricity price, and the second time period is the same length as the first time period. By changing the working time of the smart home device 2 in the second time period, the smart home device 2 works in the second power supply period corresponding to the second electricity price. Since the second electricity price is lower than the first electricity price, the second electricity fee generated by the smart home device 2 in the second time period does not exceed the electricity fee threshold, thereby realizing the management of the electricity fee in the second time period. The electricity fee threshold is pre-set by the user, and the electricity fee threshold is the total electricity fee value that the user expects to use in the second time period. In addition, when the first electricity fee does not exceed the electricity fee threshold, the controller 302 controls the smart meter 3 to supply power in the first power supply period corresponding to the first electricity price in the second time period according to the control signal. That is, in the second time period, the smart meter 3 maintains the power supply time in the first time period to supply power to the smart home device 2 in the first power supply period corresponding to the first electricity price.

[0027] Further, the control signal mainly refers to the arrangement of the start-up time and start-up duration of different smart home devices 2 in the next time range, i.e., the second time period, so that the second electricity fee in the second time period does not exceed the electricity fee threshold. In addition, the first time period and the second time period can be a week or a month, which can be determined according to the needs of the user. As an optional method, it is assumed that the power grid where the current user Mr. Wang is located usually has a low electricity consumption and low electricity fee in the time period from 22:00 to 8:00 in the morning, and other time periods are high electricity consumption and high electricity fee, that is, the time period other than the time period from 22:00 to 8:00 in the morning is the first time period, and the time period from 22:00 to 8:00 in the morning is the second time period. If the first electricity charge exceeds the electricity charge threshold, since the corresponding second electricity price in the second time period is lower than the first electricity price, some tasks of the smart home devices 2 can be completed in the second time period, such as the washing machine can wash clothes after 22:00, the tram and mobile devices such as mobile phones and iPads can be charged after 22:00, and porridge for tomorrow morning can be cooked before 8:00, etc., thereby reducing the electricity charge generated by these smart home devices 2, so that the second electricity charge generated by these smart home devices 2 in the second time period does not exceed the electricity charge threshold, thereby achieving the purpose of saving electricity.

[0028] As another preferred embodiment, the power detection module 301 can measure the power consumption in different time periods, such as the power consumption in kWh. It can not only measure the power consumption in kWh, but also measure the power consumption in each time period. For example, it can measure the power consumption in each hour, so that the electricity bill can be calculated according to the electricity price in this hour, and the power consumption in kWh can be sent to the controller 302 built into the smart meter 3. The controller 302 is communicated with the power detection module 301, and then supplies power according to a specific time period, such as in the first time period, in the first power supply period corresponding to the first electricity price. At this time, after the cloud server 1 collects the current power consumption in kWh, it can know the first electricity bill at this time in real time in combination with the first electricity price.

[0029] Furthermore, the household energy-saving housekeeper automatic control system also includes a mobile terminal 4, which is communicatively connected to the smart meter 3. More specifically, the mobile terminal 4 is communicatively connected to the controller 302. The mobile terminal 4 can be a mobile phone, a tablet, or a laptop, etc. Through these mobile terminals 4, these smart home devices 2 can be controlled, which is convenient for users to use and has a high degree of intelligence.

[0030] Furthermore, in order to ensure the safety of the user when using the smart home device 2, the smart meter 3 is used to shut down the smart home device 2 and issue a prompt message when the current flowing through the smart home device 2 is too large. The prompt message can be a buzzer or some prompting text content such as "The current working state is abnormal, please check manually" or other forms of content.

[0031] In addition, in order to achieve communication connection between the smart home device 2 and the smart meter 3, the smart home device 2 and the smart meter 3 are communicated through a WiFi module or a Bluetooth module.

[0032] In summary, the user pre-sets the electricity fee threshold and compares it with the first electricity fee. If the first electricity fee is less than the electricity fee threshold, the smart home device 2 is still powered in the first power supply period corresponding to the first electricity price during the second time period, so that the second electricity fee generated in the second time period will not be higher than the electricity fee threshold; if the first electricity fee is less than the electricity fee threshold, the smart meter 3 powers the smart home device 2 in the second power supply period corresponding to the second electricity price during the second time period according to the control signal. In this way, the working state of the smart home device 2 is well optimized, and the electricity fee expenditure can be reduced while meeting the user's life needs, thereby achieving energy conservation and emission reduction.
