Abstract

An embodiment of the invention discloses an automatic air-conditioner switching method and an automatic air-conditioner switching device. Two air conditioners alternating working can be adopted to effectively prevent service life of an air conditioner from being affected after the air conditioner is used for a long time. The switching method includes judging whether a main engine is in an operating state or not when automatic switching function is started; if the main engine is not in the operating state, then judging whether an auxiliary engine is in the operating state or not; if the main engine is in the operating state, then judging whether preset time is arrived or not; if the preset time is arrived, then closing the main engine and opening the auxiliary engine to operate; if the auxiliary engine is in the operating state, then judging whether preset time is arrived or not; and if the preset time is arrived, then closing the auxiliary engine and opening the main engine to operate. 485 chips are adopted as communication tools, so that the auxiliary engine operation can be preset to ensure that working frequency of the auxiliary engine is the same with the main engine, and problems that power rate of the auxiliary engine is limited in automatic controlling and switching methods of audion amplifying circuits in the prior art are solved.

Description

technical field

[0001] The invention relates to the field of electronic circuits, in particular to an air conditioner automatic switching method and device. Background technique

[0002] At present, in some working environments, it is necessary to run the air conditioner for a long time, the compressor is turned on and off repeatedly, the power consumption increases, and the service life of the air conditioner is affected. As a result, more and more air conditioner customers began to pay attention to the quality and service life of the air conditioner. If an air conditioner fails to work due to a problem, the working environment will not meet the requirements.

[0003] The existing technology adopts the control automatic switching scheme of the triode amplifier circuit, and there is a limit on the power of the matching slave. Contents of the invention

[0004] The embodiment of the present invention provides an air conditioner automatic switching method and device, which ...
