As shown in fig. 1, the air conditioner external unit and all the internal units are in the same communication network 1, the internal units and the line controllers are in the communication network 2, and each internal unit is connected with the line controller through a communication line.
The specific implementation case is as follows:
wired communication modes (such as CAN communication, 485 communication, HBS communication and the like) are adopted between the air conditioner external unit and the internal unit and between the internal unit and the wire controller. The three can form a relatively complete network, and each wire controller can independently control the corresponding internal machine in a wired communication mode (network 2), but cannot control other internal machines. This is the original topology of the air conditioning unit.
According to the invention, a structure in a dotted line frame is added on an original topological structure, a P L C module is added on each line controller, data are exchanged between a line controller main board and the P L C module through serial port communication, the P L C module is connected to a power grid through a power line, and data transmission is carried out by taking a power supply power line network as a data communication line, so that data interaction between the line controllers is realized.
In a preferred embodiment of the present invention, the power carrier communication module includes: a master node and a plurality of slave nodes; the wire controller is also used for setting the power carrier communication module connected with the wire controller as a main node or a slave node.

The method comprises the steps that a plurality of P L C communication networks possibly exist in the same power line network at the same time, and each P L C network is independent from each other and does not interfere with each other to ensure normal communication between devices.
In order to realize flexible control, the wire controller at least has the following control modes: a single control mode and a full control mode; the single control mode is used for controlling the target controlled equipment; the full control mode is used for controlling all controlled devices.
When the line controller enters a single control mode and the power carrier communication module corresponding to the line controller is a slave node, the line controller is used for sending a control instruction to the slave node connected with the line controller; the slave nodes connected with the slave nodes are used for sending control instructions of the wire controller to the master node, and the master node is used for sending the control instructions to the slave nodes corresponding to the target controlled equipment to control the target controlled equipment.

Each controlled device has a unique device address for identifying the controlled device; the wire controller adopts the device address of the controlled device connected with the wire controller as the control address of the wire controller.
In the scheme, the wire controller has an internal machine monitoring function and can select all internal machines for single control and full control, wherein the single control and the full control can inquire any internal machine state (switching on and off, setting temperature, wind speed, mode and the like). when the internal machine monitoring function is entered, if the single control function is selected, the wire controller (assuming that the address of the wire controller is M) controls the address N of the internal machine according to the selected target and sends a data inquiry or setting instruction to the wire controller with the same address N, the wire controller with the address N returns the state of the internal machine with the corresponding address N to the wire controller with the address M after receiving the inquiry instruction, and forwards the control instruction to the internal machine with the corresponding address N after receiving the control instruction, so as to achieve the purpose of controlling the internal machine.
The P L C equipment nodes need to have unique network addresses for identifying the equipment, and besides, when the wire controller is used for controlling other internal machines which are not connected with the wire controller through physical communication lines, the addresses of the internal machines also need to be known, because the wire controller and the internal machines have one-to-one relationship on the physical connection and can carry out one-to-one monitoring and communication in a wired communication mode, when the wire controller adopts P L C communication, the addresses of the internal machines adopt the same addresses as those of the internal machines which are physically connected, the addresses of the internal machines are identified by the external machines through unique identification codes of the internal machines and then are distributed through the network 1, and the automatic identification of the internal machines and the distribution of IP addresses are realized.
In the above embodiment, the line controllers each use the address of the controlled device connected to itself as an ID number; after receiving the ID number of the target controlled device, the power carrier communication module identifies the wire controller corresponding to the target controlled device through the ID number of the target controlled device, and sends a control instruction to the wire controller corresponding to the target controlled device to realize control over the target controlled device. After receiving the ID number of the target controlled device, the ID number of the target controlled device is sent to the main node; and the master node identifies the wire controller corresponding to the target controlled equipment according to the ID number of the target controlled equipment and sends a control instruction to the wire controller corresponding to the target controlled equipment to realize the control of the target controlled equipment.
