The invention relates to a
system and a method for diagnosing air conditioner failure based on data fusion in an internet-of-things environment. The
failure diagnosis of
air conditioning equipment is realized by analyzing and judging data in a
database of the
system for diagnosing the air conditioner failure and carrying out a corresponding decision. The
system comprises a plurality of environment modules, a plurality of air conditioner
wireless measurement and control modules, a plurality of room controllers and at least one management computer. The environment modules acquire environmental parameters of rooms; the air conditioner
wireless measurement and control modules acquire state and parameter information of air conditioners; the room controllers communicate with the environment modules and the air conditioner
wireless measurement and control modules through a
wireless sensor network, and are connected with the management computer through an
ethernet network; and the management computer performs unified management on data in a form of a
database, extracts the
environmental temperature, the
humidity, the
carbon dioxide concentration,
air conditioning parameters and the like in the
database, integrates the information to perform
data processing, comparison and analysis, and judges the states and the tendencies of the air conditioners to diagnose the air conditioner failure.
