Problems solved by technology

TCP uses bytes as the transmission unit. In the codesys-based engineering application of STEP robot controllers, the amount of data expressed by a single byte is too small to meet the actual needs.
If the mode of sending and receiving is adopted to transmit data, when the amount of data is large or the real-time requirements are high, it will lead to low efficiency. The interaction method of question and answer is not advisable

Abstract

The embodiment of the invention relates to the technical field of communication, and discloses a data transmission method and device based on a TCP protocol, electronic equipment and a medium. The data transmission method based on the TCP protocol comprises the following steps: creating a first data area according to a first data area format negotiated with a communication opposite terminal in advance; the first data area is used for storing data read from the communication opposite terminal; establishing a first transmission control protocol TCP connection with the communication opposite terminal; reading data in a first specified area of a first specified data area from the communication opposite terminal through the first TCP connection, and writing the read data into the first specified area in the first data area; the format of the first specified data area is the first data area format. Data transmission is carried out in the data areas of the communication home terminal and the communication opposite terminal, TCP communication and communication protocol formats of the communication home terminal and the communication opposite terminal do not need to be built, and efficient transmission of data streams between the communication home terminal and the communication opposite terminal can be achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a data transmission method, device, electronic equipment and medium based on the TCP protocol. Background technique [0002] Based on the most basic and efficient transmission method between devices, the transmission control protocol (Transmission Control Protocol, referred to as TCP) is used to communicate through the network port. But the biggest problem with using the TCP protocol is that TCP is transmitted in "stream" mode. In the same network flow, TCP can only guarantee byte information, and the order between bytes will not change. TCP uses bytes as the transmission unit. In the codesys-based engineering application of STEP robot controllers, the amount of data expressed by a single byte is too small to meet actual needs. If the mode of sending and receiving is adopted to transmit data, when the amount of data is large or the real-time ...
