Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
The terms "and/or", a kind of incidence relation describing affiliated partner, can there are three kinds of passes in expression
System, such as, A and/or B, can represent: individualism A, there is A and B, individualism B these three situation simultaneously.It addition, herein
Middle character "/", typicallys represent the forward-backward correlation relation to liking a kind of "or".
It should be noted that for the ease of the technical scheme clearly describing the embodiment of the present invention, at embodiments of the invention
In, have employed the printed words such as " first ", " second " and function is made a distinction with the essentially identical identical entry of effect or similar item, ability
Field technique personnel are appreciated that the printed words such as " first ", " second " are not to be defined quantity and execution order.
The inventive principle of the present invention is: first, it is determined that whether the compressor of air-conditioning can normally start, if can not, export
Corresponding Fisrt fault reason, secondly judges whether the compressor of air-conditioning can run Preset Time continuously, if can not, export
The second corresponding failure cause, if the compressor of air-conditioning can run Preset Time continuously, then obtains operation of air conditioner Preset Time
After state parameter, and obtain and export the state of air-conditioning according to the state parameter after operation of air conditioner Preset Time.
