Data transmission method and related device

Abstract

The invention discloses a data transmission method. The method comprises the following steps: determining a transmission protocol by first equipment according to the length of an obtained data packet;when the first device receives a data request sent by the second device, dividing the to-be-sent data into a plurality of data packets according to a transmission protocol, and continuously sending the plurality of data packets to the second device; and when the sending is finished, sending a data transmission finishing instruction to the second equipment, so that the second equipment performs verification processing on the received data packet according to the received verification code. When the data request is received, all the to-be-sent data is continuously sent according to the transmission protocol with the variable data length, the data transmission process is achieved, due to the fact that the length of the data packet of the transmission protocol is variable and not fixed, the data transmission process can adapt to equipment performance to conduct data transmission, and the performance utilization rate during data transmission is increased. The invention further discloses adata transmission device, computer equipment and a computer readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a data transmission method, a data transmission device, computer equipment, and a computer-readable storage medium. Background technique [0002] With the continuous development of information technology, serial interfaces appear in information equipment for data transmission. Among them, the serial interface refers to the sequential transmission of data bit by bit, and its characteristic is that the communication line is simple, as long as a pair of transmission lines can realize two-way communication, thereby greatly reducing the cost. The communication method in which the data of each bit of a message is transmitted bit by bit sequentially is called serial communication. That is to say, the transmission of data bits is carried out in bit order, and at least only one transmission line is needed to complete it, which is low in cost but slow in transmission speed...

Problems solved by technology

[0004] However, with the continuous development of computer technology, the length of the existing transmission protocol package is not conducive to the optimal performance of the hardware, that is, it leads to waste of performance during data transmission and reduces the utilization of hardware performance.
