Abstract

The invention discloses an air conditioner, a communication control method and device of the air conditioner and electronic equipment. The method includes the steps of obtaining first communication power supply voltage of a main communication power supply in the air conditioner; detecting and recognizing whether the first communication power supply voltage is lower than a first preset voltage threshold value or not; controlling the air conditioner to be switched from the main communication power supply to a standby communication power supply; and controlling the air conditioner to use the standby communication power supply for communication. According to the control method of the air conditioner, when the power supply voltage is lower than the threshold value of a regulating communicationpower supply and normal communication is not possible, a power supply of communication modules of an indoor unit and an outdoor unit is automatically switched into a reserve power supply, the communication power supply is not pulled down, normal communication of the indoor unit and the outdoor unit is ensured, the deficiency of current loop communication power supply voltage reduction caused by power grid voltage reduction is made up for, the problem of abnormal communication of the indoor unit and the outdoor unit of the air conditioner when the power grid is at low voltage can be effectivelyprevented, and thus the air conditioner can work normally under low voltage.

Description

technical field [0001] The present application relates to the technical field of air conditioners, in particular to an air conditioner and its communication control method, device and electronic equipment. Background technique [0002] At present, the communication method between the indoor unit and the outdoor unit of the inverter air conditioner generally adopts the current loop for real-time communication, and the communication between the indoor unit and the outdoor unit generally uses the fixed communication interval and the master-slave mode. baud rate. When the power grid is in a low-voltage state, the air conditioner will have insufficient current loop power supply voltage, which will cause communication failures between indoor and outdoor units. Contents of the invention [0003] This application aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, the first purpose of this application is to propose a c...
