Fan operating state determining method and system

The invention relates to a fan operating state determining method and system. The fan operating state determining method comprises the following steps: obtaining the fan operating data collected by anacquisition server; pre-treating the fan operating data to obtain time sequence fan data; according to the time sequence fan data, adopting a fan state judging model to determine the fan operating state, wherein the fan state judging model comprises affected state judgement logic, electricity generation state judgement logic, maintaining state judgement logic, halt state judgement logic and readystate judgement logic. According to the fan operating state determining method, the problem in the prior art that the operating states of fans from different fan manufacturers and with different model numbers are not consistent is solved, a unified real-time fan operating state is obtained, the fan operating data is effectively converted into the fan operating state corresponding to actual business, the data application v
