After the communication controller B receives the equipment information of the electric appliance A, the electric appliance B and the electric appliance C on the power line respectively in the pairing effective time, the control chip extracts the electric appliance identification code in the equipment information of the electric appliance, and if the identification code of the electric appliance C is not stored, the equipment information of the electric appliance C is extracted to an electric appliance selection area to be paired; the communication controller B enters a pairing mode, and after a user selects an electric appliance C to be paired in an electric appliance selection area to be paired, pairing request data containing equipment information of the communication controller B is sent to the electric appliance C to be paired through a power line; when the electric appliance C selected to be paired receives the pairing request data, if the user does not press the confirmation, the electric appliance C does not respond to the pairing request data; if the user confirms that the pairing is approved, extracting the equipment information of the communication controller B in the pairing request data and storing the equipment information in the main control board of the electric appliance, and simultaneously sending the pairing approval response data to the communication controller B; after receiving the pairing agreement response data, the communication controller B stores the equipment information of the electric appliance C selected to be paired into the paired electric appliance area in the control chip memory. When the power line carrier signal conversion device receives the equipment information of the electric appliance A, the electric appliance B and the electric appliance C on the power line within the pairing effective time, the main processor extracts the electric appliance identification codes in the equipment information of the electric appliance A, the electric appliance B and the electric appliance C, judges whether the corresponding electric appliance identification codes are stored in the control chip memory, judges that the electric appliances A and B are paired and neglect to receive the equipment information of the electric appliances A and B, and simultaneously, detects that the identification codes of the electric appliance C are not stored, stores the equipment information of the electric appliance C in the main processor, and simultaneously, transmits the consent pairing response data containing the information of the power line carrier signal conversion device to the electric appliance C (the power line carrier signal conversion device transmits consent pairing response needs user operation confirmation); and after receiving the pairing response data, the electric appliance C stores the information of the power line carrier signal conversion device into the main control board of the electric appliance.
The user wants to unpair the communication controller A and the electric appliance A, firstly, ensuring that the two parties are in a power-on state, then entering a unpairing mode in the communication controller A, selecting the electric appliance A to be unpaired from the paired electric appliances A, B and C, and sending unpairing request data containing equipment information of the communication controller A to the electric appliance A to be unpaired; after receiving the unpairing request data, the electric appliance A deletes the equipment information of the corresponding communication controller A from the electric appliance main control board, and simultaneously sends unpairing response data to the communication controller A; after receiving the unpairing response data, the communication controller A deletes the corresponding equipment information of the electric appliance A from the control chip memory.
If the pairing effective time is exceeded, all components in the intelligent home multi-machine interconnection system do not respond to pairing operation. The paired components can realize mutual data transmission and interaction, and the pairing mode can realize the pairing of all the components in the intelligent household multi-machine interconnection system, one electric appliance can be simultaneously controlled by a plurality of communication controllers, and one communication controller can also control a plurality of electric appliances and a plurality of electric appliances. The communication controllers, the cloud platform and the mobile phone terminal only process data sent by the electric appliances, the communication controllers and the mobile phone terminal do not receive and send each other, and after any communication controller changes the working parameters of the electric appliances, the electric appliances are synchronized to other paired communication controllers to ensure consistency. By adopting the mechanism, the frequency of data receiving and transmitting in the system is effectively reduced, the network load is lightened, and the applicability is improved. In addition, when all the electric appliances do not need to be connected with the external internet, the power line carrier signal conversion device can be closed or canceled, and the local internet of things formed by the electric appliances and the communication controller can still operate independently.
In another alternative embodiment, the self device information may be broadcast by the communication controller, with the appliance selecting the mateable communication controller and initiating the pairing operation.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
