Abstract

The invention belongs to the technical field of network communication, and particularly relates to a high-reliability combining and forwarding method for a multi-channel full duplex serial port, whichis suitable for being applied to wired communication between PCBs (Printed Circuit Boards) with certain distance requirements in comparison with the prior art. The technical scheme can be realized byutilizing modern relatively convenient programmable logic device deployment, and can also be realized by adopting a customized ASIC (Application Specific Integrated Circuit) mode, so that the systemcan be flexibly and conveniently helped to solve the problems. In addition, the technical scheme has relatively strong system error correction capability; the method has a better direct current balance characteristic, so that accurate deserialization can be realized at a receiving end of high-speed serial communication; and meanwhile, higher bandwidth can be provided.

Description

technical field

[0001] The invention belongs to the technical field of network communication, and in particular relates to a highly reliable combining and forwarding method of multi-channel full-duplex serial ports, which is suitable for wired communication between PCB boards requiring a certain distance. Background technique

[0002] In the field of industrial control, the serial port is a common communication interface, which is used for data transmission with small transmission bandwidth and no real-time requirements. For control system devices that require multiple serial port connections, there are several problems:

[0003] 1) The cable connection between devices is complex, requiring a large number of interfaces to be reserved;

[0004] 2) The expansion mode of the host interface is complicated;

[0005] 3) The processing host is deployed in a high-interference environment, and the serial port transmission itself has weak anti-interference ability; Contents of the...
