A qt-based cross-platform data communication method and system

Abstract

The present invention provides a QT-based cross-platform data communication method and system. The method includes: receiving communication data or file transmission data from a host computer or a lower computer; classifying and processing the communication data or file transmission data, prioritizing Level processing or sub-packet processing and forming a data packet sending queue, so that communication data or file transfer data can be transmitted between the upper computer and the lower computer with different operating systems; send the data packet sending queue to the lower computer, or Upload to the host computer. The present invention can separate and independently design the data transmission function of the bottom layer of the Ethernet network and the upper layer application program, thereby making it independent of the operating system and hardware environment, achieving the effect of unified and complete management of the network status, and further avoiding repeated work and network redundancy. This kind of conflict has good flexibility, scalability and low coupling.

Description

technical field [0001] The invention relates to the field of industrial automation control, in particular to a QT-based cross-platform data communication method and system. Background technique [0002] Driven by the development of modern science and technology, industrial technology is gradually developing in the direction of modernization, automation and intelligence. At present, industrial automation technology has become the main production technology in many industrial fields, which greatly improves production efficiency and product quality. When using industrial automation technology for production, the most important link is to do a good job in automation control. [0003] However, with the development of the industry and the increase of control equipment, it is impossible to meet the real-time data acquisition and processing requirements of various equipment in the industrial control field under the winning Kirin operating system and Windows operating system, which ...
