The present application relates to the technical field of digital communication, and discloses a method for power carrier communication transmission, including: receiving transmission request signaling sent by a communication node, and calculating the route between the central node and the communication node; Sending routing configuration signaling to the communication node, wherein the routing configuration signaling is used to set parameters for passing routing nodes; receiving data sent by the communication node along the route. By receiving the transmission request signaling frame, the end-to-end route is calculated, and the route configuration signaling is sent to each node in the route to complete the parameter setting of the route node, and then transmit the data packet according to the determined route path. In the process of data transmission, the route has been determined before the transmission of data packets, without real-time polling, thereby avoiding repeated retransmission of data packets, reducing data conflicts and collisions, and improving the reliability of data transmission. The application also discloses a device and system for power carrier communication transmission.
