The former household appliance is the power supply equipment of the latter household appliance. The adjacent household appliances can realize power supply and information intercommunication through the connecting device, and the information intercommunication between the two unconnected household appliances can be realized through the transfer information of other household appliances in the middle of the two household appliances, so that the information intercommunication can be realized for the household appliances on any two nodes in the household appliance cascade network. It can be seen that the socket 205 can provide power connection and data connection for the front and back home appliances connected to the home appliance.

The invention completes power supply connection and network connection for the household appliance through one-time connection operation, namely inserting the plug 204 of the next household appliance into the socket 205 of the previous household appliance. The household appliances in the household appliance cascade networking of the invention can realize the intercommunication among the household appliances in the cascade network without configuring hot spot information. Compared with the existing network distribution method of the Internet of things household appliances, the network selection method of the Internet of things household appliances needs to select a network for each household appliance one by one and input a corresponding user name and a corresponding password.

Fig. 3 is a schematic flow chart of a signal processing method for a household electrical appliance according to an embodiment of the present invention, and is applied to an nth-level household electrical appliance, where N is smaller than N, and N is the total number of household electrical appliances that are cascade-networked by the connection device. As shown in fig. 3, the signal processing method of the home appliance includes the following steps:

step 301: establishing power supply connection with a power supply module based on a first type of connection structure of the connection device included in the nth-level household appliance;

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 electrical appliance through a second-class connection structure of a connection device of the nth-level household electrical appliance;

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 connected in sequence 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 can be determined according to specific needs, for example, the communication identifier can be determined by the node position of the household appliance in the cascade networking, the communication identifier of the first-level household appliance is 1, the communication identifier of the second-level household appliance is 2 \8230 \ 8230, 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.

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.

It should be noted that, because the socket of the dedicated power supply device is generally a common socket, the common socket cannot transmit digital signals. Therefore, after the group plug of the first-stage household electrical appliance is inserted into the common socket, the first-stage household electrical appliance cannot establish communication connection with the special power supply equipment through the second-type connection structure of the group plug.

Further, the method further comprises:

When n is 1, the first level home device cannot receive a connection response from the previous device, as analyzed above. The first-level household electrical appliance allocates communication identifiers for the first-level household electrical appliance and the second-level household electrical appliance.

When n is larger than 1, the nth level household electrical appliance is connected with the nth-1 level household electrical appliance through the connecting device. In the case that the devices are all operating normally, the nth-level home device may receive a connection response sent by the nth-1-level home device within a predetermined time. And the nth-1 level household electrical appliance allocates a communication identifier for the nth level household electrical appliance through the connection response.

Further, the step 301 further includes:

and establishing the power supply connection with the n-1 level household electrical appliance participating in the cascade networking based on the first type of connection structure of the connection device included in the n level household electrical appliance.

As analyzed above, when n is 1, the power supply device of the nth-level household electrical appliance is a dedicated power supply device; and when n is larger than 1, the power supply equipment of the nth-level household appliance is the nth-1-level household appliance. The special power supply equipment provides power supply signals for all household electrical appliances in the whole household electrical appliance networking through the first-stage household electrical appliance equipment.

Further, the method further comprises:

In the invention, the first-level household appliance allocates the 1 st communication identifier for the first-level household appliance, the first-level household appliance allocates the 2 nd communication identifier for the second-level household appliance, the second-level household appliance allocates the 3 rd communication identifier for the third-level household appliance, and so on, all household appliances in the cascade household appliance networking are allocated with corresponding communication identifiers.

Further, the method further comprises:

receiving a first inquiry message sent by the (n-1) th-level household electrical appliance through a second-type connecting structure of the connecting device, wherein the first inquiry message contains communication identifiers of the (1) th-to (n-1) th-level household electrical appliances;

and sending a second return message to the N-1 level household electrical appliance through a second type connecting structure of the connecting device, wherein the second return message contains communication identifiers of the N-th to N-th level household electrical appliances.

The n-1 level household electrical appliance sends a first inquiry message to the n-1 level household electrical appliance, which is used for inquiring which household electrical appliances are cascaded behind the n-1 level household electrical appliance, and sends the identification of the household electrical appliance cascaded before the n-1 level household electrical appliance to the n-th level household electrical appliance and the household electrical appliance. And the nth level household appliance returns a second return message to the nth-1 level household appliance, wherein the second return message comprises the nth and the identification of the household appliance cascaded behind the household appliance. Therefore, the n-1 level household electrical appliance can acquire all communication identifiers of the whole networking household electrical appliance.

Further, the method further comprises:

receiving a first return message sent by the (N + 1) th-level household appliance through a second-class connecting structure of the connecting device, wherein the first return message contains communication identifiers of the (N + 1) th-nth-level household appliances;

after receiving a first query message which is sent by the nth-1-level household appliance and contains the communication identifiers of the 1 st to nth-1-level household appliances, the nth-level household appliance sends a second query message which contains the communication identifiers of the 1 st to nth-level household appliances to the n + 1-level household appliance. Therefore, each level of household appliances can obtain the communication identification of the household appliance cascaded before and sequentially send the inquiry message to the next household appliance.

The nth level household electrical appliance sends an inquiry message to the next equipment, and because no other cascade household electrical appliance exists, the nth level household electrical appliance cannot receive a return message within a preset time, determines that the nth level household electrical appliance is the last household electrical appliance in the cascade household electrical appliance networking, and sends the return message containing the communication identification of the nth level household electrical appliance to the nth-1 level household electrical appliance. And after receiving the return message, the N-1 level household appliance acquires the communication identifier of the subsequent cascade household appliance, and sends the return message containing the communication identifiers of the N-1 level household appliance and the N level household appliance to the N-2 level household appliance. And repeating the steps until the first-level household electrical appliance receives a return message, wherein the return message contains the communication identifiers of the second-level household electrical appliance to the Nth-level household electrical appliance.

And sequentially sending inquiry messages to the next household appliance through the first-level household appliance, and sequentially returning the identification of the cascaded household appliances behind the previous household appliance to the previous household appliance through the Nth-level household appliance. All the cascade household appliances can obtain the communication identifiers corresponding to all household appliances in the whole household appliance networking so as to communicate with other household appliances participating in the cascade networking through the communication identifiers.

Optionally, the inquiry message and the return message may include function information of all the cascaded home appliances, so that all the cascaded home appliances may obtain communication identifiers corresponding to all the home appliances in the entire home appliance networking, and may also obtain functions of all the home appliances in the entire home appliance networking, thereby facilitating scheduling of all the home appliances in the cascaded home appliance networking. For example, when detecting an abnormal condition, a video monitoring system in a home appliance networking system acquires a communication identifier of a first home appliance with an alarm function and a communication identifier of a second home appliance with a prompt function in the home appliance networking system, and sends indication information to the first home appliance and the second home appliance respectively, so that the first home appliance notifies a relevant department of immediate processing, and the second home appliance sends a prompt to a home owner.
