It should be noted that the embodiments and features of the embodiments in the present disclosure may be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Referring to fig. 1 as an aspect of the present disclosure, fig. 1 is a flowchart of a power control method for a shared appliance in this embodiment, including:

step S4: and when the total operating power exceeds the total line power capacity, determining the household appliances to be processed according to the operating power of each running shared household appliance in the building to be controlled, and sending a first control instruction for controlling the household appliances to be processed to reduce the power.
The method of the embodiment of the disclosure can be executed by a server, and the server can be a cloud, a control center and the like; as one hardware configuration of a server implementing the method of the embodiments of the present disclosure, a computer including a processing unit, a system memory, a fixed non-volatile memory interface, a mobile non-volatile memory interface, a user input interface, a network interface, a video interface, and an output peripheral interface connected via a system bus may be included, it should be noted that the hardware configuration of the server is merely illustrative and in no way implies any limitation of the present invention, its application, or use.
According to the method, when the total operating power exceeds the total line power capacity, the household appliances to be processed are determined according to the operating power, a first control instruction is sent to the household appliances to be processed to control the household appliances to be processed to reduce the power, so that after the power is reduced, the total operating power of all the running shared household appliances in the building to be controlled is lower than the total line power capacity, the total operating power of the shared household appliances cannot continuously exceed the power limit of a power supply line of the building, and the potential safety hazard of the power supply line of the building is reduced.
In step S1, a total line power capacity is obtained, where the total line power capacity is the total power capacity allocated to the shared electrical appliances by the power supply line of the building to be controlled.
In the above steps, the total line power capacity is the total power capacity allocated to the shared household appliances by the power supply line of the building to be controlled, and can be confirmed and obtained by the installer during installation; taking the shared household appliances as air conditioners, the total line power capacity, that is, the capacity allocated to the air conditioner by the power supply line of the building where the air conditioner is located, is shown in fig. 2, fig. 2 is a schematic diagram of the building line and the air conditioner architecture, and the power capacity allocated to the air conditioner by the main power supply line of the building air conditioner in fig. 2 is the total line power capacity of the architecture schematic diagram. In FIG. 2, a main power supply line of a building air conditioner is connected with a power supply base i through an air-ground line i, and an air conditioner i is connected with the power supply base i through a power line; the air conditioner i transmits information with a server (a control center or a cloud); and the server transmits the information with the mobile phone app of the user.
In step S2, the operating power of each running shared appliance in the building to be controlled is obtained;
in the above steps, the operation power of each running shared household appliance in the building to be controlled is obtained, which may be the operation power sent by all the shared household appliances, and whether the running shared household appliances are running shared household appliances in the building to be controlled is judged according to the IDs of the shared household appliances sending the operation power and the association relationship between the pre-stored IDs and the building to be controlled; the server only receives the running power sent by the shared household appliances of the building to be controlled; since the power can be calculated from the current, the received operating power can also be replaced by the current.
Step S3: calculating the total operating power of all the running shared household appliances in the building to be controlled according to the operating power of each running shared household appliance in the building to be controlled;
in the above steps, the operating powers of the shared household appliances of the building to be controlled can be added, so as to obtain the total operating power of all the shared household appliances operating in the building to be controlled.
Step S4: and when the total operating power exceeds the total line power capacity, determining the household appliances to be processed according to the operating power of each running shared household appliance in the building to be controlled, and sending a first control instruction for controlling the household appliances to be processed to reduce the power.
In the above steps, the household appliances to be processed are the shared household appliances needing power reduction; when the running power of each running shared household appliance in the building to be controlled determines the household appliance to be processed, the shared household appliance with large running power reduction margin can be selected as the household appliance to be processed according to the running power; some optional solutions for determining the household appliance to be processed according to the operating power of each running shared household appliance in the building to be controlled can be seen in the following embodiments.
In step S1, the identity information of the shared home appliances may be obtained at the same time, and the shared home appliance information and the building line form a corresponding relationship, including: the capacity of the sub-line corresponding to each household appliance is large when the household appliances are equipped in a certain building.

and step S13, sending a second control instruction to the shared household appliance with the operating power larger than the power capacity of the sub-line, wherein the second control instruction is used for controlling the shared household appliance to reduce the power below the corresponding power capacity of the sub-line.
According to the method, when the running power of the shared household appliances is larger than the power capacity of the sub-line, the power of the corresponding shared household appliances is reduced to be lower than the corresponding power capacity of the sub-line through the second control instruction, and therefore the running power of the shared household appliances is guaranteed not to exceed the corresponding power capacity of the sub-line.
In the above steps, the sub-line power capacity is dedicated for each shared household appliance; referring to fig. 2, a power supply socket i of an air conditioner sub-line i is used for supplying an air conditioner i; the sub-line power capacity of air conditioner sub-line i is the sub-line power capacity of air conditioner i. If the operating power of the air conditioner i exceeds the sub-line power capacity of the air conditioner sub-line i, the fact that the operating power of the shared household appliance (the air conditioner i) is larger than the sub-line power capacity of the shared household appliance can be judged.
The power capacity of the sub-line in the above steps can be confirmed by an installer when the shared household appliance is installed; and storing the sub-line power capacity of the shared household appliance in the server, it can be known that the sub-line power capacity of the shared household appliance stored in the system can be the shared household appliance ID and the sub-line power capacity paired with the shared household appliance ID.
As can be appreciated, the second control command can include a sub-line power capability corresponding to the shared appliance.
The above steps may be performed before step S3, and the advantage of performing before step S3 is that the above steps are relatively fast to calculate, and when the sub-line power capacity is exceeded, belonging to line overload operation, the power must be reduced in time. In the above steps, after the second control command is sent, the process may return to step S2 again to obtain a new operating power, so that steps S3 and S4 are calculated according to the latest operating power.

Ninthly, calculating the power limit value P _ i _ limit _ calc of the n air conditioners which are operated beyond the power weighted value P _ i _ avg _ r allowed by each air conditioner, and finally calculating the power limit value P _ i _ limit _ calc as P _ i-P _ i _ over _ avg _ r.
Logic below the R, the control center or the cloud judges whether each air conditioner needs to reduce power or not, and sends the calculated power limit value P _ i _ limit _ calc to the air conditioner needing to reduce power.
(7) And after receiving the information of the calculated power limit value, the air conditioner executes the calculation according to the limit value. The user-set operating parameters must comply with this limit.
In the step (6), the running air conditioners can be changed into all air conditioners to participate in calculation, and the actual power of the air conditioners which are not in operation is marked as 0.
The step (5) may be replaced by: and the control center or the cloud sends the sub-line power capacity P _ i _ limit to each corresponding air conditioner, and each air conditioner controls the power per se not to exceed the sub-line power capacity P _ i _ limit in the running process.
