Data transmission method and related equipment

Abstract

According to the data transmission method and the related equipment. In the method, after acquisition equipment acquires a message instruction sent by an upper computer, Ethernet equipment identifies and determines a message corresponding to the message instruction, then extracts information of a source MAC address, a source IP address and a source port number in the message, packs the extracted information, and transmits resultant packets to the upper computer. Thus, locking of the acquisition equipment is realized, directional transmission of output data of the acquisition equipment is realized, reliability of data transmission is guaranteed, and in the scheme, the output message of the acquisition equipment is bound to the fixed port of the system through the resultant packets, so that the port can only acquire the uploaded data of the specific acquisition equipment, thus, the process of identifying, analyzing and processing the message uploaded by the acquisition equipment by the driving layer is reduced, the data transmission efficiency is improved, the real-time performance of system data transmission is ensured, and the data transmission process is relatively simple.

Description

technical field [0001] The invention relates to the technical field of communication engineering, in particular to a data transmission method and related equipment. Background technique [0002] With the development of science and technology and actual needs, a complete control system often needs to establish a complex test platform before it is put into use, and a large number of experiments are used to strictly ensure the correctness and safety of the system. For example, a distributed experimental platform composed of data acquisition systems and simulation systems for various sensor signals on the aircraft. In view of the experimental requirements, the experiment needs to be carried out through multi-sensor / computer collaboration, and the functions of sensor data collection / storage / monitoring / playback / simulation need to be completed. [0003] Real-time communication is required between the various distributed systems that are being tested. Ethernet is the most widely us...

AI Technical Summary

Problems solved by technology

[0007] On the one hand, large and complex network environments such as aircraft test platforms are usually not suitable for static routing, and it is difficult for users to fully understand the topology of the entire network

On the other hand, when the network topology and link status change, the static routing information in the router needs to be adjusted on a large scale. The difficulty and complexity of this work is very high, and the work pressure of the router will also be great.

When the network changes or the network fails, the route cannot be reselected, which may cause the route to fail

Thereby affecting the conduct of platform experiments

Due to the need to exchange routing information with each other, dynamic routing occupies network bandwidth and system resources (CPU time, memory, and link bandwidth), which will complicate the data transmission of the experimental platform
