Taking an air conditioner ducted air conditioner as an example, the blowing port has no fixed wind-sweeping function, and the ducted air conditioner needs to have a wind-sweeping function. Therefore, a blowing port component with a wind-sweeping function and a communication function needs to be externally connected at the blowing port.

Therefore, when the wire controller or the blowing port component fails, it will affect the entire communication network, resulting in air conditioner communication failure and unable to operate normally.

[0073] The selection module 10 includes a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, a fifth transistor Q5, a sixth transistor Q6, a seventh transistor Q7 and a switch K1. Figure 2The third output end Ctrl of the processor is connected with the first end of the fifth resistor R5, the second end of the fifth resistor R5 is connected with the first end of the sixth resistor R6, the second end of the sixth resistor R6 is connected with the first end of the seventh resistor R7 and the first end of the switch K1, the second end of the switch K2 is connected with the first end of the seventh transistor Q7, the second end of the seventh transistor Q7 is grounded, the third end of the seventh transistor Q7 is connected with the power supply VCC and the third input end of the second control module 30, the second end of the seventh resistor R7 is connected with the first end of the fifth transistor Q5, the third end of the fifth transistor Q5 is connected with the power supply VCC, the second end of the fifth transistor Q5 is connected with the first end of the sixth transistor Q6, the second end of the sixth transistor Q6 is grounded, the third end of the sixth transistor Q6 is connected with the power supply VCC and the third input end of the first control module 20 respectively, and the third end of the switch K1 is connected with the third input end of the first control module 20.

[0074] The third output end Ctrl of the processor can output different voltage values, the first output end Ctrl1 of the first selection module 10 controls the on or off of the communication of the drive-by-wire device, and the second output end Ctrl2 of the first selection module 10 controls the on or off of the communication of the air port component. When the first output end Ctrl1 and the second output end Ctrl2 of the first selection module 10 are both at the on level (for example, high level), the communication of the drive-by-wire device and the air port component are both on, when the first output end Ctrl1 and the second output end Ctrl2 of the first selection module 10 are both at the off level (for example, low level), the communication of the drive-by-wire device and the air port component are both off, and the switch K1 is on at the on level and off at the off level.

[0075] When the third output end Ctrl of the processor outputs 0V, the switch K1 is off, and the fifth transistor Q5, the sixth transistor Q6 and the seventh transistor Q7 are all off, at this time, the first output end Ctrl1 and the second output end Ctrl2 of the first selection module 10 are both at the on level, and the communication of the drive-by-wire device and the air port component are both on; when the third output end Ctrl of the processor outputs the voltage at point A as shown in the figure, which meets the on condition of the switch K1 and does not meet the on condition of the fifth transistor Q5, the switch K1 and the seventh transistor Q7 are both on, and the fifth transistor Q5 and the sixth transistor Q6 are both off, at this time, the second output end Ctrl2 of the first selection module 10 is at the off level, and the first output end Ctrl1 of the first selection module 10 is at the on level, so that the communication of the air port component is off, and the communication of the drive-by-wire device is on; when the third output end Ctrl of the processor outputs the voltage at point B as shown in the figure, which meets the on condition of the fifth transistor Q5 and does not meet the on condition of the switch K1, the fifth transistor Q5 and the sixth transistor Q6 are both on, and the switch K1 and the seventh transistor Q7 are both off, at this time, the first output end Ctrl1 of the first selection module 10 is at the off level, and the second output end Ctrl2 of the first selection module 10 is at the on level, so that the communication of the drive-by-wire device is off, and the communication of the air port component is on. Figure 2 Figure 2 ​When the voltage of the B point meets the conduction condition of the fifth transistor Q5, the switch K1 and the seventh transistor Q7 are both disconnected, and the fifth transistor Q5 and the sixth transistor Q6 are both conducted. At this time, the second output end Ctrl2 of the first selection module 10 is at a conduction level, and the first output end Ctrl1 of the first selection module 10 is at a disconnection level. Therefore, the communication of the tuyere component is conducted, and the communication of the line controller is disconnected.

[0076] Under normal circumstances, the third output end Ctrl of the processor outputs 0V, the switch K1 is disconnected, and the fifth transistor Q5, the sixth transistor Q6, and the seventh transistor Q7 are not conducted. At this time, the first output end Ctrl1 and the second output end Ctrl2 of the first selection module 10 are both at a conduction level, and the communication of the line controller and the tuyere component are both conducted.

[0077] Based on the above communication control circuit, as shown in Figure 3 The method can specifically include the following steps:

[0078] S301, in the case that the air conditioner has a communication fault, determining a fault query order, wherein the fault query order is a fault query order of the line controller and the tuyere component.

[0079] In the embodiment of the application, in the case that the air conditioner has a communication fault, the fault query order is determined, wherein the fault query order is a fault query order of the line controller and the tuyere component, that is, which one of the line controller and the tuyere component is queried first.

[0080] For the fault query order, there are generally two kinds. The first order is to query the tuyere component first and then the line controller, and for the second order, the line controller is queried first and then the tuyere component. The embodiment of the application does not limit this.

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

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

[0083] The level of the first output end of the selection module controls the communication of the line controller to be conducted or disconnected, and the level of the second output end of the selection module controls the communication of the tuyere component to be conducted or disconnected. By controlling the voltage output by the third output end of the processor, the level of the first output end and the level of the second output end of the selection module can be controlled, and the recovery result of the communication fault can be obtained, that is, the communication fault is recovered or not.

[0084] S303, according to the recovery result of the communication fault, the voltage output by the third output end of the control processor is controlled to control the level of the first output end and the level of the second output end of the selection module.

[0085] In the embodiment of the application, for the recovery result of the communication fault, the voltage output by the third output end of the control processor can be controlled according to the recovery result of the communication fault to control the level of the first output end and the level of the second output end of the selection module, thereby controlling the communication on or off of the drive-by-wire controller and the air outlet component.

[0086] In the case of the first sequence of the fault query sequence, the voltage output by the third output end of the control processor (for example, the voltage output by the third output end Ctrl of the control processor to point A as shown in the figure satisfies the on condition of the switch K1 and does not satisfy the on condition of the fifth transistor Q5) is controlled to control the first output end of the selection module to be the on level and the second output end to be the off level, wherein when the first output end of the selection module is the on level, the communication of the drive-by-wire controller is on, and when the second output end of the selection module is the off level, the communication of the air outlet component is off. Figure 2 In the case of the recovery result of the communication fault indicating that the communication fault is recovered, it is indicated that the air conditioner communication fault is caused by the air outlet component fault, and thus the air outlet component fault can be determined. The voltage output by the third output end of the control processor is controlled to control the first output end of the selection module to be the on level and the second output end to be the off level, thereby controlling the communication of the drive-by-wire controller to be on and the communication of the air outlet component to be off.

[0087] In the case of the recovery result of the communication fault indicating that the communication fault is not recovered, the voltage output by the third output end of the control processor (for example, the voltage output by the third output end Ctrl of the control processor to point B as shown in the figure satisfies the on condition of the fifth transistor Q5) is controlled to control the first output end of the selection module to be the off level and the second output end to be the on level, wherein when the first output end of the selection module is the off level, the communication of the drive-by-wire controller is off, and when the second output end of the selection module is the on level, the communication of the air outlet component is on.

[0088] Figure 2 In the case of the recovery result of the communication fault, it is indicated that the air conditioner communication fault is caused by the drive-by-wire controller fault, and thus the drive-by-wire controller fault can be determined. The voltage output by the third output end of the control processor is controlled to control the first output end of the selection module to be the off level and the second output end to be the on level, thereby controlling the communication of the drive-by-wire controller to be off and the communication of the air outlet component to be on.

[0089] In the case of the recovery result of the communication fault, it is indicated that the air conditioner communication fault is caused by the drive-by-wire controller fault, and thus the drive-by-wire controller fault can be determined. The voltage output by the third output end of the control processor is controlled to control the first output end of the selection module to be the off level and the second output end to be the on level, thereby controlling the communication of the drive-by-wire controller to be off and the communication of the air outlet component to be on.
