Data transmission method for realizing RTU multi-protocol dynamic loading

The invention discloses a data transmission method for realizing RTU multi-protocol dynamic loading. The method comprises the steps of firstly, performing parameter configuration according to a selected protocol; then, performing loading and initialization in a whole network so that the protocol is operated in the whole network, hereon performing framing and transmission on various kinds of basic data information of a data acquisition unit by an RTU embedded protocol stack according to the selected protocol, and simultaneously finishing transmission supplementing according to an algorithm strategy; and finally, analyzing and restoring original data at a central station or another data receiving end according to the selected protocol algorithm, and performing response, thereby finishing a data receiving and transmitting whole-process. The data transmission method can settle a problem of dynamically configuring and loading multiple application layer protocols and furthermore improves adaptability of RTU data tr
