This invention discloses a dual-mode communication method for the power Internet of Things (IoT) based on deep learning for channel estimation, relating to the field of power IoT communication technology. The method includes: designing a unified MAC layer protocol and setting a bit error rate (BER) requirement factor field in the data frame structure; obtaining power line and low-power wireless communication link parameters based on this, and determining the optimal communication path by introducing perturbation parameters; processing the initial channel matrix using deep learning to generate feature channel weights and perform residual connections, outputting channel state information; dynamically adjusting the BER requirement factor using a gradient adjustment method and calculating the sub-stream allocation ratio; and splitting the service data into sub-streams proportionally and transmitting them through corresponding links. This invention achieves intelligent selection of power IoT communication links and adaptive allocation of service data.
