Abstract

The invention discloses a communication control method and device for an air conditioning system, an air conditioning system, a storage medium and a processor. The method includes: after the current internal machine among two or more internal machines is powered on, the current internal machine itself determines the bus Whether there is a wired controller on the bus; if there is a wired controller on the bus, if the current internal machine itself is the upper computer, the current internal machine itself is switched from the upper computer to the lower computer; the current internal machine itself is the lower computer. If there is no wire controller on the bus, the current internal unit itself will be switched to the upper computer, so that the current internal unit itself can be used as the upper computer to control the other two or more internal units. Communication between internal units. In this solution, when it is determined that there is no wire controller on the bus network, an internal machine is determined and the internal machine is switched to a host computer to realize communication interaction among other internal machines.
