Abstract

The invention discloses a data transmission protocol method. The data transmission protocol method is used for data transmission between a client and a host computer, and comprises: a step S1 of performing bit merging for original data to obtain a combined synchronous frame, wherein the size of the original data is M bytes, each byte has N bits, and the synchronous frame successively comprises a synchronous frame head, the frame number of asynchronous frames, data bits of the plurality of asynchronous frames and a synchronous frame end from beginning to end; a step S2 of transmitting the combined synchronous frame; a step S3 of receiving the combined synchronous frame; and a step S4 of performing bit decomposition for the asynchronous frame data in the combined synchronous frame to recoverthe original data. Through adoption of the data transmission protocol method of the invention, defects that synchronous serial communication is high in efficiency but short in communication distanceand asynchronous serial communication is long in transmission distance but low in efficiency can be avoided, different asynchronous frame bits are selected, a bit stream can be obtained through automatic merging when data is transmitted, and data bytes can be obtained through automatic decomposition when the data is received; therefore, transmission efficiency is improved in the case of ensuring reliable long-distance transmission.

Description

technical field [0001] The invention relates to the technical field of remote bus communication, in particular to a data transmission protocol method. Background technique [0002] With the increasing popularity of computer network communication, the construction of a communication platform between computers is becoming more and more important. Synchronous serial communication has high efficiency but short communication distance, and asynchronous serial communication has long transmission distance but low efficiency. At present, the communication line quality and anti-interference of serial communication are good. In order to speed up the transmission efficiency, the present invention uses the method of learning from each other to improve the transmission efficiency in the case of long-distance transmission. Contents of the invention [0003] The purpose of the present invention is to provide a data transmission protocol method for the deficiencies in the prior art. [...
