[0028] In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions in the present application will be described clearly and completely in combination with the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present application.

[0029] Figures 1-3 The structural schematic diagram of the communication system of the air conditioner controller and the air conditioner indoor unit provided by the present application is described. Figure 1 The system includes the air conditioner outdoor unit 1, at least two air conditioner indoor units 2 and at least two controllers 3. The air conditioner outdoor unit 1 and the at least two air conditioner indoor units 2 are connected in sequence through the communication bus 4. The air conditioner indoor unit 2 and the controller 3 correspond to each other in communication. The controller 3 listens to the communication bus 4.

[0030] Further, the structural schematic diagram of the communication system of the air conditioner controller and the air conditioner indoor unit provided by the present application is described. Figure 2The controller 3 determines whether to take over the corresponding abnormal air conditioner indoor unit 21 based on the monitored communication failure. The communication failure is uploaded to the communication bus 4 by the abnormal air conditioner indoor unit 21 based on the communication abnormality with the corresponding controller. Based on the determination of taking over, the controller 3 controls the abnormal air conditioner indoor unit 21 according to the monitored communication failure.

[0031] In an optional embodiment, the communication bus is a PQ communication bus.

[0032] In an optional embodiment, the controller 3 determines whether to take over the corresponding abnormal air conditioner indoor unit 21 based on the monitored communication failure. Figure 2 Before the controller 3 monitors the communication bus and determines whether to take over the corresponding abnormal air conditioner indoor unit 21 based on the monitored communication failure, the abnormal air conditioner indoor unit 21 sends the communication failure to other normal air conditioner indoor units 22 through the communication bus 4 based on the communication abnormality between the air conditioner indoor unit and the corresponding controller.

[0033] It should be noted that before the abnormal air conditioner indoor unit 21 sends the communication failure to other normal air conditioner indoor units 22 through the communication bus 4 based on the communication abnormality between the air conditioner indoor unit and the corresponding controller, the communication abnormality between the air conditioner indoor unit and the corresponding controller is determined. Specifically, the air conditioner indoor unit 2 and the corresponding controller 3 communicate in real time. When the controller 3 sends a control signal to the corresponding air conditioner indoor unit 2, the air conditioner indoor unit 2 returns an acknowledgement signal. If the controller 3 does not receive the acknowledgement signal, it is determined that the communication is abnormal. The air conditioner indoor unit 2 determines that the communication is abnormal based on the fact that it does not receive the communication signal from the corresponding controller 3.

[0034] In addition, when the air conditioner indoor unit and the corresponding controller are in communication abnormality, the abnormal air conditioner indoor unit 21 and the corresponding controller will report a communication failure. The abnormal air conditioner indoor unit 21 generates a communication failure according to the fault code and the indoor unit address and reports it to the communication bus 4. The controller 3 displays a fault icon and a fault code.

[0035] In an optional embodiment, the communication failure is transmitted by the abnormal air conditioner indoor unit to the corresponding air conditioner indoor unit through the communication bus based on the preset air conditioner indoor unit takeover sequence received in advance, and after the controller of the corresponding air conditioner indoor unit refuses to take over, the abnormal air conditioner indoor unit sends the communication failure to the next air conditioner indoor unit in the preset air conditioner indoor unit takeover sequence. The preset air conditioner indoor unit takeover sequence is set by the controller based on the room position information of each air conditioner indoor unit and sent to the corresponding air conditioner indoor unit.

[0036] Specifically, based on the communication abnormality of the air conditioner indoor unit and the corresponding controller, the abnormal air conditioner indoor unit 21 sends the communication failure to other normally communicating air conditioner indoor units 22 through the communication bus 4, including: based on the communication abnormality, the abnormal air conditioner indoor unit 21 transmits the communication failure to other normally communicating air conditioner indoor units through the communication bus 4 according to the preset air conditioner indoor unit takeover sequence received in advance. Correspondingly, the controller listens to the communication bus, including: the controller 3 listens to the communication bus 4 of the corresponding air conditioner indoor unit 2.

[0037] In addition, the controller 3 listens to the communication bus 4, and based on the communication failure obtained by listening, determines whether to take over the corresponding abnormal air conditioner indoor unit 21, including: based on the controller that listens to the communication failure, the abnormal air conditioner indoor unit 21 transmits the communication failure to the next air conditioner indoor unit through the communication bus according to the preset air conditioner indoor unit takeover sequence.

[0038] It should be noted that the abnormal air conditioner indoor unit realizes intelligent selection of taking over the air conditioner indoor unit according to the preset air conditioner takeover sequence sent by the controller. For example, in a home environment, there are children's room, adult room, old people's room and guest room, when the air conditioner indoor unit and the controller of the children's room are in communication abnormality, the preset air conditioner indoor unit takeover sequence can be: first the adult room, second the old people's room, and last the living room. Correspondingly, the air conditioner indoor unit of the children's room sends the communication failure to the air conditioner indoor unit of the adult room through the communication bus according to the preset air conditioner indoor unit takeover sequence; the controller of the adult room obtains the communication failure based on listening to the communication bus of the corresponding air conditioner indoor unit, and determines whether to take over, if taking over, controls the air conditioner indoor unit of the children's room to synchronize with the running state of the air conditioner indoor unit of the adult room, if refusing to take over, sends a refusal signal to the corresponding air conditioner indoor unit of the adult room; the air conditioner indoor unit of the adult room sends a refusal takeover signal to the air conditioner indoor unit of the children's room through the communication bus; the air conditioner indoor unit of the children's room sends the communication failure to the air conditioner indoor unit of the next old people's room through the communication bus according to the preset air conditioner indoor unit takeover sequence, and the subsequent communication logic of the adult room is referred to above, which will not be further described here.

[0039] In another optional embodiment, based on the communication abnormality of the air conditioner indoor unit and the corresponding controller, the abnormal air conditioner indoor unit 21 sends the communication failure to other normally communicating air conditioner indoor units 22 through the communication bus 4, and also includes: based on the communication abnormality, the abnormal air conditioner indoor unit 21 transmits the communication failure to all other normally communicating air conditioner indoor units 22 through the communication bus 4.

[0040] It should be noted that in the case of communication exception of the air conditioner indoor unit, the communication bus is used to transmit the communication failure to all other normally communicating air conditioner indoor units. The controller corresponding to the other normally communicating air conditioner indoor units confirms whether to take over based on the monitored communication failure, and after any controller confirms to take over, the air conditioner indoor unit corresponding to the takeover controller sends a takeover signal to the communication bus, and the remaining normally communicating controllers cancel the takeover confirmation of the abnormal air conditioner indoor unit based on the monitored takeover signal.

[0041] In an optional embodiment, based on the communication exception of the air conditioner indoor unit and the corresponding controller, the abnormal air conditioner indoor unit 21 sends the communication failure to other normally communicating air conditioner indoor units through the communication bus, including: if at least two air conditioner indoor units and the corresponding controller communicate abnormally, at least two abnormal air conditioner indoor units 21 respectively send the corresponding communication failure to other normally communicating air conditioner indoor units through the communication bus 4.

[0042] Correspondingly, based on the monitored communication failure, it is determined whether to take over the corresponding abnormal air conditioner indoor unit, including: the controller 3 monitors the communication bus of the corresponding air conditioner indoor unit to obtain at least two abnormal failures, and according to the indoor unit address of the abnormal air conditioner indoor unit 21 corresponding to the abnormal failure, it is confirmed in turn whether to take over the corresponding abnormal air conditioner indoor unit 21.

[0043] In addition, with reference to Figure 3 , based on the communication exception of the air conditioner indoor unit and the corresponding controller, the air conditioner indoor unit sends the communication failure to other normally communicating air conditioner indoor units through the communication bus, and also includes: if at least two air conditioner indoor units and the corresponding controller communicate abnormally, each abnormal air conditioner indoor unit 21 respectively sends the corresponding communication failure to other normally communicating air conditioner indoor units 22 through the communication bus 4 according to the preset air conditioner indoor unit takeover sequence sent by the corresponding controller.

[0044] It should be noted that if the communication failure of at least two abnormal air conditioner indoor units 21 is sent to different normally communicating air conditioner indoor units 22, the corresponding controller 3 confirms whether to take over based on the monitored communication failure; if the communication failure of at least two abnormal air conditioner indoor units 21 is sent to the same normally communicating air conditioner indoor unit 22, the corresponding controller 3 confirms whether to take over in turn according to the indoor unit address of the abnormal air conditioner indoor unit 21, which can be specifically referred to as described above, and will not be further described here.

[0045] It should be noted that when there are n air conditioner indoor units, and n-1 air conditioner indoor units and the corresponding controllers communicate abnormally, the n-1 abnormal air conditioner indoor units report the communication failure to the communication bus; the controller of the normally communicating air conditioner indoor unit monitors n-1 communication failures, and confirms whether to take over in turn according to the indoor unit address of each abnormal air conditioner indoor unit.

[0046] In an optional embodiment, the controller 3 listens to the communication bus 4, and determines whether to take over the corresponding abnormal air conditioner indoor unit 21 based on the communication failure listened to, including: the controller 3 listens to the communication bus 4, and obtains the indoor unit address of the corresponding abnormal air conditioner indoor unit 21 based on the communication failure listened to; the controller 3 determines whether to take over the air conditioner indoor unit in the first order of the abnormal air conditioner indoor unit according to the preset air conditioner indoor unit takeover sequence and the indoor unit address of the abnormal air conditioner indoor unit, and takes over the corresponding abnormal air conditioner indoor unit 21 based on taking over the air conditioner indoor unit in the first order; otherwise, the takeover is refused.

[0047] In an optional embodiment, based on the confirmation of the takeover, the corresponding controller 3 controls the abnormal air conditioner indoor unit 21 according to the communication failure listened to, including: based on the confirmation of the takeover, the corresponding controller obtains the indoor unit address of the abnormal air conditioner indoor unit 21 according to the communication failure listened to; the controller 3 taking over sends the obtained indoor unit address to the corresponding communication air conditioner indoor unit 22; the air conditioner indoor unit 22 sends the running state to the abnormal air conditioner indoor unit 21 through the communication bus 4 according to the received indoor unit address.

[0048] In summary, the embodiment of the application realizes communication between the air conditioner outdoor unit and at least two air conditioner indoor units through the communication bus, and uses the controller in one-to-one communication with each air conditioner indoor unit to listen to the communication bus, so that when the communication failure between the air conditioner indoor unit and the controller occurs on the communication bus, the remaining controllers determine whether to take over based on the communication bus listened to, so as to select the required controller to take over the operation of the corresponding communication abnormal air conditioner indoor unit as needed, ensure that the air conditioner indoor unit abnormal communication does not affect the normal use of the user, improve the user experience, and reduce the defective rate.
