All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
the appearances of the phrases "first," "second," and "third," or the like, in the specification, claims, and figures are not necessarily all referring to the particular order in which they are presented. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
the invention discloses a charging method based on the Internet of things, which comprises the following steps: the electric meter obtains an electric price table; the ammeter acquires the residual quantity of the electric quantity of each household appliance battery through each sensor; the sensors correspond to the household appliances one by one; the sensor is used for monitoring the residual quantity of the electric quantity of the corresponding household appliance battery; the ammeter determines the battery with the electric quantity residual quantity smaller than a first preset threshold value as a target battery; the ammeter compares the current time with the electricity price table to determine whether the current time is in a low electricity price stage; and when the current moment is in the low electricity price valley stage, the electric meter charges the target battery.
Referring to fig. 1, fig. 1 is a charging method based on the internet of things according to an embodiment of the present invention. As shown in fig. 1, a charging method based on the internet of things according to an embodiment of the present invention includes the following steps:
s101, the electric meter acquires an electricity price table.
the intelligent electric meter is an intelligent electric meter, and can be understood that the intelligent electric meter is an intelligent terminal of an intelligent power grid, and the intelligent electric meter has intelligent functions such as bidirectional multi-rate metering function, user side control function, bidirectional data communication function of multiple data transmission modes, electricity larceny prevention function and the like in order to adapt to the use of the intelligent power grid and new energy besides the metering function of the basic electricity consumption of the traditional electric meter.
the electric meter is used as a controller of a user side, and household appliances with residual electric quantity smaller than a preset threshold value can be automatically charged according to the wave crest and the wave trough of the electricity price.
Specifically, the electric meter can automatically acquire the electric price table provided by the electric power company from the network. For example, the electricity price table may be obtained from the official website of the electric power company every preset time period; of course, whenever the electric power company updates the electric price meter, the electric price meter is pushed to the smart electric meters in the district of the electric power company. After receiving the electricity rate table, the electricity rate table is updated by the new electricity rate table. Of course, the electricity meter may send a prompt at a preset point in time to let the user know the contents of the electricity rate meter. Of course, the prompting method includes voice prompt or dialog prompt; the electricity meter may also transmit the electricity rate table to the mobile phone of the bound user so that the user can know the latest electricity rate information.
note that the electricity rate table includes electricity rates corresponding to each time period. For example, 6 at night: 00-10: 00 is the peak period of electricity consumption of residents, and the electricity price of the electricity consumption of the residents is higher at the moment; 9 in the morning: 00-12: 00 is the underestimation period of the electricity consumption of the residents, and the electricity consumption price of the residents is lower at the moment.
And S102, the electric meter obtains the electric quantity residual quantity of each household appliance battery through each sensor.
The sensors correspond to the household appliances one by one; the sensor is used for monitoring the electric quantity residual quantity of the corresponding household appliance battery.
It is understood that common household appliances, which have a battery mounted therein, include a dust collector, a shaver, a washing machine, and the like. Each household appliance is bound with a sensor; the sensor is used for monitoring the residual capacity of the household appliance battery.
s103, the ammeter determines the battery with the electric quantity residual quantity smaller than a first preset threshold value as a target battery.
For example, a battery having a capacity of less than 60% may be determined as the target battery. That is, the sensor can acquire the percentage of the remaining power of the home appliance bound thereto.
Of course, the sensor may also obtain the current remaining power and the total power, and then send the current remaining power and the total power to the electric meter, which calculates the percentage of the remaining power of each household appliance, for example, the remaining power is divided by the total power to calculate the percentage of the remaining power.
S104, the ammeter compares the current time with the electricity price table to determine whether the current time is in an electricity price low valley stage.
Wherein, the ammeter is with the present moment with the electricity price table is compared in order to confirm whether the present moment is the low valley stage of electricity price, include: the electric meter traverses the information of the electricity price table to determine a time period corresponding to the electricity price low valley stage; the ammeter compares the current time with the time period corresponding to the electricity price valley stage to determine whether the current time is within the time period corresponding to the electricity price valley stage; and when the current time is determined to be in the time period corresponding to the electricity price low valley stage, determining that the current time is the electricity price low valley stage.
For example, the time period such as the electricity price trough is 9 a.m.: 00-12: 00, the current time is 11 a.m.: 00; then 11: 00 is in the time period of the electricity price trough.
and S105, when the current moment is in the low price valley stage, the ammeter charges the target battery.
it can be understood that charging the target battery in the low price valley period can not only meet the charging requirement, but also save the electricity fee.
there are many ways to charge the battery, such as wired charging or wireless charging.
For example, there is a battery in the washing machine, and the battery of the washing machine is the target battery; then when the current time is in the low price valley period, the wireless charger may be turned on to charge the washing machine through the wireless charger. Specifically, for example, when the washing machine is arranged, a charging coil, which is a wireless charger, may be mounted on a corresponding wall of the washing machine.
Optionally, the electric meter compares the current time with the electricity price table to determine whether the current time is before the electricity price valley stage, and the method further includes: the ammeter judges whether the battery residual quantity of the target battery is smaller than a second preset threshold value or not; wherein the second preset threshold is smaller than the first preset threshold; and when the residual quantity of the target battery is smaller than a second preset threshold value, charging the battery with the residual quantity of the electric quantity smaller than the second preset threshold value in the target battery.
optionally, after the battery with the remaining amount of power smaller than a second preset threshold in the target battery is charged, the method further includes: detecting whether the residual quantity of the charged target battery is larger than a third preset threshold value or not; wherein the third preset threshold is smaller than the first preset threshold and larger than the second preset threshold; and when the fact that the residual quantity of the charged target battery is larger than a third preset threshold value and the current moment is not in the low price stage is detected, stopping charging.
For example, the first preset threshold is 80%, the third preset threshold is 50%, and the second preset threshold is 20%.
in addition, the first preset threshold, the second threshold and the third preset threshold may be determined according to the living habits of the user. For example, the number of charges charged by each machine in the past preset time period is counted by using a machine learning algorithm. The more the number of charges, the higher the three preset thresholds.
The method comprises the steps that average charging times X, a first default threshold value A, a second default threshold value B and a third default threshold value C of a certain electric appliance within a preset time period can be obtained;
The electric meter counts the charging times Y of the electric appliance in a preset time period; adjusting an actual first preset threshold M, a second preset threshold P and a third preset threshold Q according to the ratio of Y/X;
Wherein, M ═ Y/X) × a, P ═ Y/X) × B, and Q ═ Y/X) × C.
Optionally, before the electric meter obtains the remaining quantity of the electric quantity of the battery of each household appliance through each sensor, the method further includes: the electric meter acquires the identifier of each sensor from the sensor management table; the ammeter sends heartbeat information to each sensor according to the identifier of each sensor so as to determine whether each sensor is in an on state; and when detecting that each sensor is in an on state, sending an electric quantity consumption feedback request to each sensor so that each sensor feeds back the electric quantity residual quantity of the household appliance battery.

Therefore, by implementing the technical scheme provided by the invention, the electric appliance which is connected with the power supply and has the battery capacity smaller than the preset threshold value can be charged in the low price, so that the charging requirement is met and the cost is reduced.

S202, the electric meter obtains the electric quantity residual quantity of each household appliance battery through each sensor;
Optionally, before the electricity meter obtains the remaining amount of the electricity of the battery of each household appliance through each sensor, the method further includes: the electric meter acquires the identifier of each sensor from the sensor management table; the ammeter sends heartbeat information to each sensor according to the identifier of each sensor so as to determine whether each sensor is in an on state; and when detecting that each sensor is in an on state, sending an electric quantity consumption feedback request to each sensor so that each sensor feeds back the electric quantity residual quantity of the household appliance battery.

s205, when the current moment is determined not to be in the time period corresponding to the electricity price low valley stage, the ammeter judges whether the battery residual quantity of the target battery is smaller than a second preset threshold value or not;
wherein the second preset threshold is smaller than the first preset threshold;
