This can significantly reduce the efficiency of the inter-device communication.

The Power Line Carrier communication technology (PLC) is a common technology for communication between current intelligent devices, and can utilize the existing Power Line to transmit analog or digital signals at high speed in a Carrier mode, thereby realizing communication between devices. Therefore, the communication between the air conditioning system and other intelligent equipment can also be applied to the power line carrier communication technology. Because the communication carrier of the power line carrier communication technology is a power line, under the condition of three-phase power, common single-phase PLC equipment cannot perform communication transmission with other PLC equipment across the three-phase power, that is, under the environment of three-phase power, PLC equipment in the phase a cannot perform communication with PLC equipment in the phase C. This can significantly reduce the efficiency of the inter-device communication.

At present, if power line carrier cross-phase communication is to be realized in the prior art, a three-phase coupler is required to be used. The three-phase coupler can couple the signal of the phase A to the phase B \ C. However, the three-phase coupler is a hardware product, and all signals on a certain phase are coupled to other phases without filtering. Thus, when a plurality of networks exist in the power line, the coupling method without filtering increases the communication pressure between the intelligent devices, and also reduces the communication efficiency between the devices.

The embodiment of the application provides an air conditioning system and a control method thereof, and a three-phase coupler is added to a PLC gateway of an outdoor unit of the air conditioning system through a mobile device of a user in a mode of software and hardware, so that the three-phase coupler records the address of the PLC gateway of the outdoor unit. Therefore, when the three-phase coupler identifies that the networking signal is from the gateway address recorded by the coupler, the networking signal is forwarded to other phases, and cross-phase communication among the PLC communication module devices is achieved. The method can improve the conditions of message increase and communication pressure increase when the hardware equipment three-phase coupler is used for realizing the cross-phase communication between the equipment, and the air conditioning system can accurately send signals to the corresponding equipment and receive the signals sent by the corresponding equipment to the air conditioning system, thereby improving the communication efficiency between the equipment.
