step 302: acquiring energy consumption for executing a predetermined function based on the power supply connection;
step 303: allocating an n +1 communication identifier to the n + 1-level household appliance cascaded with the n-level household appliance;
step 304: sending the (n + 1) th communication identifier to the (n + 1) th-level household appliance through a second-class connection structure of a connection device of the nth-level household appliance;
the (n + 1) th communication identifier is used for the (n + 1) th-level household appliance to communicate with other household appliances participating in the cascade networking through a second-class connection structure of the connection device.
The household electrical appliance can be a household electrical appliance used in daily life of people, and comprises: kitchen appliances, entertainment appliances, communication appliances, and the like.
As described above, the plug of each household appliance is inserted into the socket of the previous appliance, so that a plurality of household appliances are sequentially connected to form a linear household appliance networking. The household appliance networking comprises N household appliance devices, wherein N is a positive integer larger than 1.
The power supply equipment can be the former household appliance, a power socket or power generation equipment and the like. In the household electrical appliance networking, each household electrical appliance has a unique communication identifier, the communication identifiers of all the household electrical appliances are different, the household electrical appliances correspond to the communication identifiers one to one, the household electrical appliances corresponding to the identifiers can be uniquely determined through the communication identifiers, and then each household electrical appliance is communicated with other household electrical appliances participating in the cascading networking through the communication identifiers.
When the tame electric installation is first level tame electric installation, above-mentioned power module is special power supply unit's power module, and special equipment includes: power outlets or power generating equipment, etc. When the household appliance is not the first-level household appliance, the power supply module is the power supply module of the previous household appliance.
The communication identifier may be determined according to specific needs, for example, the communication identifier may be determined by a node position of the household appliance in the cascade networking, where the communication identifier of the first-level household appliance is 1, and the communication identifier of the second-level household appliance is 2 … …, and the communication identifier of the nth-level household appliance is N. It may also be determined in accordance with a predetermined function of the home appliance, and the communication identifier of the refrigerator is "fridge", the communication identifier of the washing machine is "washing", and so on.
Further, the step 301 includes:
and if n is 1, establishing power supply connection with the special power supply equipment by using the first-class connection structure of the connection device contained in the nth-class household appliance equipment.
And when n is 1, the household appliance is a first-level household appliance, and the household appliance needs to be connected with a special power supply device to provide power supply signals for all household appliances in the whole household appliance networking. The special power supply equipment can be a power socket or power generation equipment and the like.
When n is 1, the power supply equipment of the nth-level household electrical appliance is special power supply equipment; and when n is larger than 1, the power supply equipment of the nth-level household appliance is the nth-1-level household appliance.
