[0002] As living standards improve, the demand for products also increases. In order to meet market demand, more external devices are needed to meet it. Take the ducted air conditioner as an example. Its air outlet has no air sweeping function, which is fixed. Now the ducted air conditioner needs to be able to sweep the air. For this reason, an air outlet component with both air sweeping and communication functions needs to be externally mounted at the air outlet. The air outlet component, the wired controller, and the ducted air conditioner are connected to the same communication network.

[0003] Since the air outlet components, wire controller and duct unit are connected to the same communication network, the communication mode of the air outlet components, wire controller and duct unit is a bus-type communication mode. The characteristic of the bus-type communication mode is that if one of the devices interferes with the bus, the entire communication network will not be able to communicate normally, resulting in communication abnormalities. Therefore, when the wire controller or air outlet component fails, it will affect the entire communication network, causing the air conditioner to report a communication failure and be unable to operate normally.

[0074] Among them, for the third output terminal Ctrl of the processor, different voltage values ​​can be output, the first output terminal Ctrl1 of the first selection module 10 controls the conduction or disconnection of the communication of the wire controller, and the second output terminal Ctrl2 of the first selection module 10 controls the conduction or disconnection of the communication of the air outlet component. When the first output terminal Ctrl1 and the second output terminal Ctrl2 of the first selection module 10 are both at the conduction level (for example, a high level), the communication between the wire controller and the air outlet component is conducted, and when the first output terminal Ctrl1 and the second output terminal Ctrl2 of the first selection module 10 are both at the disconnection level (for example, a low level), the communication between the wire controller and the air outlet component is disconnected, and the switch K1 is turned on at the conduction level and disconnected at the disconnection level.

[0076] Under normal circumstances, the third output terminal Ctrl of the processor outputs 0V, the switch K1 is disconnected, the fifth transistor Q5, the sixth transistor Q6, and the seventh transistor Q7 are all not turned on, at this time, the first output terminal Ctrl1 and the second output terminal Ctrl2 of the first selection module 10 are both at the on level, and the communication between the wire controller and the air outlet component is turned on.

[0077] Based on the above communication control circuit, such as Figure 3 FIG. 1 is a schematic diagram of an implementation flow of a communication control method provided in an embodiment of the present application. The method may specifically include the following steps:

[0078] S301, when there is a communication fault in the air conditioner, determining a fault query sequence, wherein the fault query sequence is a fault query sequence of a wire controller and an air outlet component.

[0079] In an embodiment of the present application, when there is a communication failure in the air conditioner, a fault query order is determined, wherein the fault query order is the fault query order of the wire controller and the air outlet component, that is, which one of the wire controller and the air outlet component is prioritized for querying whether there is a fault.

[0080] There are generally two types of fault query sequences. The first sequence is to query the air outlet components first, followed by the wire controller, while the second sequence is to query the wire controller first, followed by the air outlet components. The embodiments of the present application do not limit this.

[0081] S302, according to the fault query sequence, control the voltage outputted by the third output terminal of the processor to control the level of the first output terminal and the level of the second output terminal of the selection module.

[0082] In the embodiment of the present application, for the fault query sequence, the voltage output by the third output terminal of the processor can be controlled according to the fault query sequence to control the level of the first output terminal and the level of the second output terminal of the selection module.

[0083] Among them, the level of the first output end of the selection module controls the communication of the wire controller to be turned on or off, and the level of the second output end of the selection module controls the communication of the air outlet component to be turned on or off. In this way, the voltage output by the third output end of the processor is controlled to control the level of the first output end and the level of the second output end of the selection module, and the recovery result of the communication failure can be obtained, that is, the communication failure is recovered or not.

[0084] S303, according to the recovery result of the communication failure, controlling the voltage outputted by the third output terminal of the processor to control the level of the first output terminal and the level of the second output terminal of the selection module.

[0085] In an embodiment of the present application, for the recovery result of the communication failure, the voltage output by the third output terminal of the processor can be controlled according to the recovery result of the communication failure to control the level of the first output terminal and the level of the second output terminal of the selection module, thereby controlling the communication conduction or disconnection of the wire controller and the air outlet component.

[0086] Wherein, when the fault query sequence is the first sequence, the voltage outputted by the third output terminal of the control processor (for example, the third output terminal Ctrl of the processor is outputted to Figure 2 The voltage at point A shown meets the conduction condition of the switch K1 but does not meet the conduction condition of the fifth transistor Q5), so as to control the first output end of the selection module to be at a conduction level and the second output end to be at a disconnection level, wherein when the first output end of the selection module is at a conduction level, the communication of the wire controller is conducted, and when the second output end of the selection module is at a disconnection level, the communication of the air outlet component is disconnected.

[0087] When the recovery result of the communication failure indicates that the communication failure has been recovered, it means that the air conditioner communication failure was caused by a failure in the air outlet component. From this, it can be determined that the air outlet component has failed, and the voltage output by the third output terminal of the control processor is controlled to control the first output terminal of the selection module to be at a conduction level and the second output terminal to be at a disconnection level, thereby controlling the communication of the wire controller to be conducted and the communication of the air outlet component to be disconnected.

[0088] In the case where the communication fault recovery result indicates that the communication fault has not been recovered, the voltage output by the third output terminal of the control processor (for example, the third output terminal Ctrl of the processor is output to Figure 2 The voltage at point B shown satisfies the conduction condition of the fifth transistor Q5), so as to control the first output end of the selection module to be at a disconnection level and the second output end to be at a conduction level, wherein when the first output end of the selection module is at a disconnection level, the communication of the wire controller is disconnected, and when the second output end of the selection module is at a conduction level, the communication of the air outlet component is connected.

[0089] When the communication failure is recovered, it means that the air conditioning communication failure is caused by the wire controller failure. Therefore, the wire controller failure can be determined. The voltage output by the third output terminal of the control processor is controlled to control the first output terminal of the selection module to be at the disconnect level and the second output terminal to be at the on level, thereby controlling the communication of the wire controller to be disconnected and the communication of the air outlet component to be on.

[0090] If the communication failure is not restored, it indicates that the air conditioning communication failure is caused by the failure of the wire controller and the air outlet component. Therefore, it can be determined that both the wire controller and the air outlet component are faulty, and the air conditioner is controlled to shut down. The voltage output by the third output terminal of the control processor is controlled to control the first output terminal of the selection module to be at the disconnect level and the second output terminal to be at the disconnect level, thereby controlling the communication of the wire controller and the air outlet component to be disconnected.

[0091] When the fault query sequence is the second sequence, the voltage output from the third output terminal of the control processor is used to control the first output terminal of the selection module to be at a disconnect level and the second output terminal to be at a conduction level, wherein when the first output terminal of the selection module is at a disconnect level, the communication of the wire controller is disconnected, and when the second output terminal of the selection module is at a conduction level, the communication of the air outlet component is conducted.

[0092] When the recovery result of the communication failure indicates that the communication failure has been recovered, it means that the air conditioning communication failure was caused by the wire controller failure. From this, it can be determined that the wire controller failure is occurring. The voltage output by the third output terminal of the control processor is controlled to control the first output terminal of the selection module to be at a disconnect level and the second output terminal to be at a conduction level, thereby controlling the communication of the wire controller to be disconnected and the communication of the air outlet component to be conducted.

[0093] When the recovery result of the communication fault indicates that the communication fault has not been recovered, the voltage output by the third output terminal of the control processor is used to control the first output terminal of the selection module to be at an on level and the second output terminal to be at a disconnect level, wherein when the first output terminal of the selection module is at an on level, the communication of the wire controller is turned on, and when the second output terminal of the selection module is at a disconnect level, the communication of the air outlet component is disconnected.

[0094] When the communication failure is recovered, it means that the air conditioner communication failure is caused by the failure of the air outlet component. Therefore, the failure of the air outlet component can be determined, and the voltage output by the third output terminal of the control processor is controlled to control the first output terminal of the selection module to be at the on level and the second output terminal to be at the off level, thereby controlling the communication of the wire controller to be on, while the communication of the air outlet component is disconnected.

[0095] If the communication failure is not restored, it indicates that the air conditioning communication failure is caused by the failure of the wire controller and the air outlet component. Therefore, it can be determined that both the wire controller and the air outlet component are faulty, and the air conditioner is controlled to shut down. The voltage output by the third output terminal of the control processor is controlled to control the first output terminal of the selection module to be at the disconnect level and the second output terminal to be at the disconnect level, thereby controlling the communication of the wire controller and the air outlet component to be disconnected.

[0096] The communication control method provided in the embodiment of the present application is described below with reference to specific examples. Figure 4As shown. When there is a communication fault in the air conditioner, the voltage output by the third output terminal of the control processor is controlled to control the first output terminal of the selection module to be the on level and the second output terminal to be the off level, so that the communication of the wire controller is controlled to be on and the communication of the vent component is disconnected. If the communication fault is restored at this time, the voltage output by the third output terminal of the control processor is controlled to control the first output terminal of the selection module to be the on level and the second output terminal to be the off level, so that the air conditioner can operate normally, and the wire controller displays a fault code indicating that the vent component is damaged. If the communication fault is not restored at this time, the voltage output by the third output terminal of the control processor is controlled to control the first output terminal of the selection module to be the off level and the second output terminal to be the on level, so that the communication of the wire controller is controlled to be disconnected and the communication of the vent component is connected. If the communication fault is restored at this time, the voltage output by the third output terminal of the control processor is controlled to control the first output terminal of the selection module to be the off level and the second output terminal to be the on level, so that the communication of the wire controller is controlled to be disconnected and the communication of the vent component is connected. If the communication fault is not restored at this time, it means that both the wire controller and the vent component are faulty, and the air conditioner is controlled to stop.
