Embodiment

[0090] Examples of the present invention are figure 1 and figure 2 shown.

[0091] The specific process of sending data is:

[0092] The data received by the serial port is encapsulated into data packets according to the specified packet format and stored in the packet generation module.

[0093] The data packaged by the packet generation module is input into the module for encoding according to the input data bandwidth requirement of the RS encoding module.

[0094] The encoded data is divided into single-byte data streams by the slicing module and delivered to the 8b / 10b encoding module to obtain the DC balance characteristics of the data stream.

[0095] The parallel-to-serial conversion module converts the 10-bit data with DC balance characteristics into a 1-bit data stream and sends it to the single-ended to differential module.

[0096] The single-ended to differential module is responsible for realizing the sending action of the physical layer.

Abstract

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. Compared with the prior art, the invention is suitable for wired communication between PCB boards requiring a certain distance. This technical solution can be implemented by deploying modern and more convenient programmable logic devices, or by custom ASIC, which can help the system solve the above problems flexibly and conveniently. Moreover, the technical solution has a strong system error correction capability; it has better DC balance characteristics, which facilitates accurate deserialization at the receiving end of high-speed serial communication; and at the same time, it can provide higher bandwidth.

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...
