The embodiment of the invention provides an inter-network physical isolation one-way data transmission method and a data transmission system, and relates to the technical field of information security. The method is applied to a sending end terminal device of a data transmission system, and comprises the following steps: receiving encrypted data, splitting the encrypted data into a plurality of groups of data packets according to a preset size to serve as to-be-coded data packets, coding each to-be-coded data packet, and sending the coded data packets to a sending end terminal device of the data transmission system, and sending the to-be-coded data packets to obtain to-be-displayed data in all the to-be-coded data packets, and displaying the to-be-displayed data on a plurality of predetermined display areas in a display form of 0-F. According to the embodiment of the invention, the coding and display modes in the unidirectional data transmission are simplified, and the decoding difficulty in the unidirectiona
