The invention discloses an adaptive ACT communication method. The method comprises: step 1, establishing wired and wireless communication connections among nodes; step 2, selecting a modulation mode for communication nodes; step 3, selecting a communication medium for the communication nodes; and step 4, determining a communication mode of the communication nodes. The method solves the technical problems that network communication isolated nodes are caused when nodes failing in communication appear in a wired or wireless communication mode due to the adoption of a single communication medium in the prior art, so that the communication coverage of a system declines, the reliability declines and the like.
