Example 1

This embodiment provides a method for controlling the power consumption of household appliances in combination with the framework shown in FIG. 1 . The method mainly involves a power measurement module, a home appliance, a power control system and a power grid information monitoring module. Each household appliance is equipped with a power measurement module. Each power measurement module can be directly plugged into the household socket, and then the household appliance plug is directly inserted into the power measurement module, so as to periodically obtain the first work of its monitoring home appliances. information; or the power measurement module can also be directly embedded in the control board of the home appliance to directly detect the power consumption of each home appliance periodically, and through the communication interface of the home appliance itself, the first working information of the home appliance and its own second 2. Transmission of work information to the power control system; add the ID of the power measurement module to the power control system, and after matching the ID of the power measurement module with the ID of the home appliance on the power control system, the power measurement module can communicate with the power control system. The power data can be transmitted between the measurement module and the power control system in a wireless mode, or in a wired way, such as power line carrier or radio frequency; the power control system can be installed in a smart terminal, and the smart terminal can be placed in the A suitable location in the home; the grid information monitoring module is directly connected to the meter through the power line carrier communication, monitors the usage status of the entire grid in real time, and directly reads the grid usage information of the current user from the grid.

As shown in Figure 2, the method in this embodiment mainly includes:

101. At least one power measurement module periodically reports the first work information of the monitored household appliances and the second work information of the power measurement module to the power control system;

Wherein, in this embodiment and the following embodiments, the first working information of the home appliance includes: the electricity consumption of the home appliance and the working status of the home appliance; the second working information of the power measurement module includes: the power consumption of the power measurement module working status.

In this embodiment, after receiving the first work information and the second work information reported by each power measurement module, the power control system will save the first work information and the second work information, and can even detect The information periodically reported by the module corresponds to updating the first work information and the second work information.

For example, the power measurement module 1 monitoring the household appliance 1 periodically reports the power consumption and working status of the household appliance 1 and the working status of the power measurement module 1 to the power control system. Correspondingly, the power control system will periodically receive and save the power consumption and working status of the household appliance 1 reported by the power measurement module 1, as well as the working status of the power measurement module 1, and can even periodically The power consumption and working status of the household appliance 1 and the working status of the power measurement module 1 are updated.

102. The power control system determines the working state of the power control system according to the power grid usage information obtained by the power grid information monitoring module;

Wherein, the power grid usage information obtained by the power grid information monitoring module may specifically include: the load status of the power grid, and the total power consumption of users to which the power control system belongs.

Specifically, 102 can be implemented in the following ways:

When the load status of the power grid acquired by the grid information monitoring module is greater than the peak threshold, determine that the working state of the power control system is an energy-saving mode;

When the load status of the grid acquired by the grid information monitoring module is less than the valley threshold, determine that the working state of the power control system is the energy consumption mode;

When the grid load status acquired by the grid information monitoring module is within the normal threshold range, it is determined that the working state of the power control system is the normal mode.

103. The power control system controls the working state of the corresponding home appliance according to the determined working state and the first and second working information reported by the at least one power measurement module.

Specifically, in combination with the energy-saving mode, energy-consuming mode and normal mode in 102 above, this 103 can be realized in the following manner:

When the working state is the energy-saving mode, the power control system searches for the high-power household appliances in use that are greater than the high power threshold according to the first working information and the second working information (generally, household appliances with a power consumption greater than 2 kilowatts are defined as high-power household appliances), and control the high-power household appliances to enter the energy-saving mode of the household appliances themselves, or turn off the power supply of the high-power household appliances through the corresponding power measurement module;

When the working state is the energy consumption mode, the power control system searches for the low-power household appliances in use that are smaller than the low-power threshold according to the first working information and the second working information, and controls the low-power household appliances to enter the household appliances themselves energy consumption mode;

When the working state is the normal mode, the power control system controls the home appliance to restore the last working state according to the last saved working state of the home appliance, and sets the home appliance into a state controlled by the user.

In addition, the method of this embodiment also provides an alarm mechanism for home appliance failure, so as to deal with the scene of home appliance failure. This mechanism can be realized by adding a working state (that is, an alarm mode) in the power control system. The alarm mode is the mode with the highest priority in the power control system, which is higher than the energy saving mode, normal mode and energy consumption mode.

As shown in Figure 3, the methods of the alarm mechanism mainly include:

301. Each household appliance has its corresponding standard set amount of electricity consumption when it is working. For example: when the refrigerator is in normal operation, the standard set amount of power consumption is 150 watts; when defrosting, the standard set amount of power consumption is 180 watts, etc. When the power measurement module monitors that the current power consumption of the home appliance does not meet the standard set amount, the power measurement module sends an alarm command to the power control system;

302. The power control system performs fault detection according to fault detection rules, and after determining that a fault occurs, controls the power measurement module to power off, and notifies a user according to a preset contact strategy.

Specifically, the above-mentioned main method can be realized in the following manner: as shown in Figure 4,

401. After the power measurement module discovers that the monitored home appliance is abnormal, it actively sends a fault alarm command to the power control system. After receiving the alarm command, the power control system determines whether the current power of the home appliance exceeds the limited standard setting power. If yes, execute 402; otherwise, execute 403;

402. The power control system turns off the power of the household appliance by operating the power measurement module, and continues to execute 404;

403. The power control system judges whether the current working state of the home appliance exceeds the standard set power under the working state, and if so, executes 405; otherwise, executes 404;

404. The power control system sends a text message (or sends an email, or a recorded phone call, etc.) to notify the user of the failure of the home appliance, and saves the relevant information about the failure of the home appliance for use by the failure center for detection, and the process ends.

405. If the user presets the power standard for the home appliance in the power control system, judge whether the power of the home appliance exceeds the preset power standard, and if so, go to 406; otherwise, go to 407;

406. The power control system executes actions preset by the user, for example, turning off the home appliance, etc., and ends this process;

407. The power control system executes according to the default operation, and ends this process.

With the protection of the above-mentioned alarm mechanism, even in the case of a failure of the home appliance, it can be guaranteed to reduce the loss of the user and ensure the safety of the home appliance.

In addition, in order to cope with various situations, in this embodiment, the above-mentioned energy-saving mode can be further divided into multiple levels, and the judgment standard of each level corresponds to a different peak threshold, and the peak threshold can be set by the operator as a default value, It can also be set by the user; similarly, the energy consumption mode can be further divided into multiple levels, and the judgment standard of each level corresponds to a different valley threshold, and the valley threshold can be set by the operator as a default value, or by the user set up.

Combined with the three working states mentioned above in 102 (energy saving mode, energy consumption mode and normal mode), the three control modes corresponding to the power control system mentioned in 103 in the three working states, energy saving mode and energy consumption mode It can be further divided into multiple levels, and the scheme of the alarm mode that realizes the alarm mechanism is described in detail:

Energy-saving mode: the power control system obtains the grid usage information of the substation in the community through the grid information monitoring module (including the grid load status and the total power consumption of the users to which the power control system belongs), and judges whether the grid is in power consumption according to the grid load status Peak, when it is determined to be a peak of power consumption, the power control system is adjusted to work in an energy-saving mode. When the power control system enters the energy-saving mode, it starts to count the data according to the first work information (including the power consumption and working status of the home appliance monitoring home appliances) and the second work information (the working status of the power measurement module) reported by each power measurement module. According to the household appliances being used in the user's home at that time, the household appliances and the working status of the household appliances working at this time are determined according to the household appliances being used and the degree of the peak of the power grid.

The power control system divides the peak degree of the grid into three levels of 1, 2, and 3 by default according to the grid load. The power control system defaults to a level 1 grid load condition when the overload is greater than 30% of the first peak threshold and less than 60% of the second peak threshold; the power control system defaults to the grid load condition when the overload is greater than 60% of the second peak threshold, and When it is less than 90% of the third peak threshold, it is level 2; the power control system defaults to the grid load status as level 3 when the overload is greater than 90% of the third peak threshold.

When the peak degree of the power grid is the default level 1, the power control system can select the large power consumption greater than the high power threshold that is being used according to the power consumption of household appliances reported by each power measurement module, the working status of household appliances, and the total power consumption of users. high-power household appliances, and control these high-power household appliances to enter the first-level energy-saving mode of the household appliances themselves. Do control adjustments.

When the peak degree of the power grid is the default level 2, the power control system can select the high power in use that is greater than the high power threshold according to the power consumption of household appliances reported by each power measurement module, the working status of household appliances, and the total power consumption of users. home appliances, and control these high-power home appliances to enter the 2-level energy-saving mode of the home appliance itself. For example, in addition to the air conditioner entering its own energy-saving mode, the set temperature will be 2 degrees higher or lower than the preset temperature of the energy-saving mode depending on the cooling or heating mode; the water heater will stop using at this time; the refrigerator will not In modes that increase energy consumption such as defrosting, the washing machine does not adjust.

When the peak level of the power grid defaults to level 3, the power control system controls the home appliances being used to enter the level 3 energy-saving mode of the home appliance itself according to the power consumption of the home appliances reported by each power measurement module, the working status of the home appliances, and the total power consumption of the user , or directly turn off the power supply of high-power household appliances by operating the power measurement module. For example, directly cut off the power supply of the air conditioner, water heater and washing machine, and the refrigerator enters the energy-saving mode of the machine.

Normal mode: the power control system obtains the grid usage information of the substation in the community through the grid information monitoring module (including the grid load status and the total power consumption of the users to which the power control system belongs), and judges whether the grid is at the normal threshold according to the grid load status Within the range, when it is determined that the usage is within the normal threshold range, the power control system is adjusted to work in the normal mode. When the power control system enters the normal mode, control these home appliances to restore their last working state according to the last saved working state of each home appliance, and set the home appliances to enter the state controlled by the user. Therefore, in this mode, the switches of all home appliances maintain the settings used by the user, and the power control system does not actively turn on and off any home appliances. Unless the user sets the normal mode, all settings of the home appliances in this mode are all controlled by the user.

Energy consumption mode: the power control system obtains the grid usage information of the substation in the community through the grid information monitoring module (including the load status of the grid, and the total power consumption of the users to which the power control system belongs), and judges whether the grid is in use according to the load status of the grid. Electric wave valley, when it is determined to be an electric wave valley, adjust the working state of the power control system to the energy consumption mode. When the power control system enters the energy consumption mode, it starts to count according to the first work information (including the power consumption and working status of home appliances monitoring appliances) and the second work information (working status of the power measurement module) reported by each power measurement module At this time, the household appliances being used in the user's home are determined according to the household appliances being used and the degree of the valley of the power grid to determine the working household appliances and the working status of the household appliances at this time.

The power control system divides the trough degree of the grid into three levels of 1, 2, and 3 by default according to the grid load. The power control system defaults to level 1 when the grid load condition is less than 99% of the first valley threshold and greater than or equal to 80% of the second valley threshold; the power control system defaults to the grid load condition when the overload is less than 80% of the second peak threshold and greater than or equal to When the third valley threshold is 60%, it is level 2; when the default power grid load condition of the power control system is less than 60% of the third valley threshold, it is level 3.

When the trough level of the grid defaults to level 1, the power control system can select the low power in use that is less than the low power threshold according to the power consumption of household appliances reported by each power measurement module, the working status of household appliances, and the total power consumption of users. Home appliances, and control these low-power home appliances to enter the first-level energy consumption mode of the home appliances themselves. For example, the refrigerator will enter the defrosting mode, and the air conditioner, water heater, etc. will maintain the original working state set by the user and will not be adjusted.

When the peak load of the power grid is at level 2 of the valley level, the power control system can select the household appliances in use that are greater than the high power threshold according to the power consumption of household appliances reported by each power measurement module, the working status of household appliances, and the total power consumption of users , and control these home appliances to enter the level 2 energy consumption mode of the home appliance itself. For example, the water heater will automatically enter the high-power boiling water mode, and the temperature set by the air conditioner will be lower or higher than the preset temperature by 2 degrees depending on the cooling or heating mode.

When the trough degree of the power grid is the default level 3, the power control system controls each home appliance to enter the level 3 energy-saving mode of the home appliance itself according to the power consumption of the home appliance reported by each power measurement module, the working status of the home appliance, and the total power consumption of the user. For example, the power control system turns on the non-working water heater and other high-power household appliances by operating the power measurement module to make them start to work.

Alarm mode, in this mode, the power failure of home appliances caused by various reasons or exceeding the user's preset value are handled in this mode. The working mode of several other states is that the power control system actively queries the status of each power policy module and home appliances. In this mode, the power measurement module is allowed to actively send fault alarms to the power control system until the power control system confirms that it has received the fault. alarm.

All default settings in the above power control system can be changed by the user. Including the judgment threshold and classification method of the peak and trough of the power grid, the corresponding home appliance actions, and the associated actions of home appliances, etc. Users can also make settings that limit the operation of any mode of the power control system.

The method provided in this embodiment, combined with the load status of the power grid to control the working mode of the home appliance, can control the home appliance to enter the energy consumption state when the power of the power grid is high, which can not only make full use of the power, but also avoid energy loss caused by power loss. When the power is low, control the home appliances to enter the energy-saving state, which can not only reduce the load burden on the power grid, but also ensure the power consumption of other users, and also save the power consumption of home appliances, which not only improves the energy-saving consumption of home appliances, but also makes reasonable use of the power grid of electric energy. In particular, in the future development process, in order to avoid waste of resources, the State Grid may adopt a time-sharing power supply strategy. The home appliances will automatically enter the appropriate energy consumption mode to use electric energy to avoid the technical effect of power loss in vain; when the power grid reduces the power supply, through the control of the power control system, the home appliances will also automatically enter the appropriate energy-saving mode to save energy. , can not only save the user's electricity cost, but also reduce the technical effect of the load burden on the power grid.
