The invention discloses a
system and a method for the centralized control of a central air conditioner based on a graphical interface. The
system comprises a centralized controller, master control boards and a mobile terminal, wherein the master control boards are respectively mounted in all
air conditioning units of the central air conditioner; the centralized controller is used for respectively acquiring status parameters of all the
air conditioning units from all the master control boards through serial buses; the mobile terminal is used for acquiring the
bus addresses and status parameters of all the
air conditioning units from the centralized controller in a
wireless manner; the mobile terminal is further used for displaying a real-
scene graph similar to a mounted place of each air conditioning unit of the central air conditioner, displaying the graph of the related air conditioning unit corresponding to the real-
scene graph and displaying the name of the related air conditioning unit and status parameters of the related air conditioning unit with a
bus address associated with the related air conditioning unit name corresponding to the graph of the related air conditioning unit. According to the
system and the method, the central air conditioner is controlled based on the graphical interface by using the mobile terminal, so that the
control manner is flexible and convenient, and the needs of users can be better met.
