Multi-frequency redundant wireless transmission method and device based on TDMA

The invention relates to a multi-frequency redundant wireless transmission method and device based on TDMA, and belongs to the technical field of communication. The method comprises the steps: setting a data packet header for target data, and obtaining to-be-sent data, wherein the data packet header comprises a source address and a serial number; copying the to-be-sent data to obtain N identical to-be-sent data, wherein each wireless radio frequency module corresponds to one piece of data to be sent; for each wireless radio frequency module, when the current time reaches the starting time of the TDMA superframe corresponding to the wireless radio frequency module, sending the corresponding to-be-sent data to a receiving end through the wireless radio frequency module; enabling different wireless radio frequency modules to correspond to starting time of different TDMA superframes; when a part of channels are interfered by the same frequency, still ensuring that the data packets can be transmitted to the receiv
