Abstract

The invention discloses a method for switching the communication mode of an air conditioner. There are multiple communication modes between the first heat exchange device and the second heat exchange device of the air conditioner. The method for switching the communication mode of the air conditioner includes: Assuming that the first heat exchange device has not received the information transmitted by the second heat exchange device within the time period, determine the current communication mode between the first heat exchange device and the second heat exchange device; control the first heat exchange device to communicate with the second heat exchange device through the current communication mode. The heat exchange device sends a check code; when the second heat exchange device does not receive the check code within a second preset time period, the current communication mode is switched to a standby communication mode. The invention also provides an air conditioner and a readable storage medium. Because the air conditioner can switch the current communication mode to the standby communication mode when the current communication mode fails, the air conditioner can avoid the situation that the air conditioner cannot operate due to the communication terminal, and improve the reliability of the communication between the internal and external units of the air conditioner, thereby improving the communication efficiency of the air conditioner. user experience.

Description

technical field [0001] The present invention relates to the technical field of air conditioner communication, in particular to an air conditioner communication mode switching method, an air conditioner and a readable storage medium. Background technique [0002] Because the distance between the indoor unit and the outdoor unit of the air conditioner is relatively far, the communication between the chips of the indoor unit and the outdoor unit cannot be directly connected, and a driving circuit must be added in the middle to enhance the communication signal and resist external interference. [0003] With the popularization of air conditioners and the improvement of people's living standards, air conditioners are often in long-term operation. When the communication between the indoor unit and outdoor unit of the air conditioner is interrupted, the air conditioner cannot operate. The reliability of the communication between the internal and external units of the air conditioner ...
