A reliable data transmission system and method based on multi-channel fusion

Abstract

The invention provides a reliable data transmission system based on multi-channel fusion, the system comprises a source end and a destination end, and the source end comprises a channel link monitoring device, a channel multiplexing device, a channel fusion subpackaging device and a channel fusion confirmation device; the destination end comprises a channel fusion response device; Wherein the channel link monitoring device detects whether the communication state of a first channel is abnormal or not; If the first channel is abnormal, the channel multiplexing device selects a second channel tocontinue to transmit data, and the channel fusion subpackaging device performs subpackaging operation on the data to perform data transmission; After the source end sends data through the second channel, the channel fusion response device of the destination end receives and feeds back the data; And the channel fusion confirmation device confirms a data transmission result according to the feedback. According to the invention, a multi-channel transmission mechanism is optimized in real time, the real-time performance of data transmission in a multi-channel network is improved, and the reliability of data transmission is improved.

Description

technical field [0001] The invention relates to the technical field of data communication under a narrowband network, in particular to a reliable data transmission system and method based on multi-channel fusion. Background technique [0002] Data communication in a narrowband network environment mostly adopts a data transmission mode based on a single channel; even if multiple communication channels coexist, the data transmission between each channel is independent of each other, such as figure 1 shown. [0003] For example, Chinese Utility Model Patent Publication No. CN206350172U discloses a comprehensive multi-channel access adapter device, which includes a power supply module for supplying power to the device, and also includes a main control chip. The main control chip is connected to an interface circuit, and the interface circuit includes Channel port, remote control port, LAN port, three serial ports, miniPCIE interface, two of the serial ports are connected to the...

AI Technical Summary

Problems solved by technology

[0006] 1) When a single channel communication fails or is interrupted, cross-channel transmission conversion requires manual intervention, system switching and other assistance, resulting in delays in the continuation of data transmission, which is not real-time;

[0007] 2) There are packet loss and repackage problems in cross-channel data transmission, and the reliability cannot be guaranteed;

[0009] 4) During the transmission process, there are problems of data loss (partial data is transmitted in the previous channel) and duplication of data transmission (the subsequent channel transmits the data already transmitted in the previous channel)
