Problems solved by technology

[0003] There are a variety of bus mechanisms in the industry, but none of them can fully meet these requirements, for example
[0004] 1. The high-speed parallel bus can meet the real-time requirements, but cannot meet the isolation requirements between different nodes;
[0005] 2. Network communication can meet the isolation requirements, but cannot meet the real-time requirements;
[0006] 3. The CAN bus meets the requirements of isolation and real-time performance, but cannot achieve high-speed communication
However, this invention is aimed at CAN bus communication, and due to its own limitations, high-speed communication cannot be achieved

Abstract

The invention relates to a communication system based on M-LVDS real-time multi-homed high-speed buses. The communication system comprises a system A, a system B, and a M-LVDS bus, wherein each of thesystem A and the system B comprises a plurality of nodes, the nodes in the system A or the system B are interconnected through a backboard or PCB cabling; the nodes between the system A and the system B are interconnected through the M-LVDS bus. Compared with the prior art, the communication system disclosed by the invention has the advantages of being high speed, real-time, isolated and flexiblein networking.

Description

technical field [0001] The invention relates to the field of bus communication, in particular to a communication system based on M-LVDS real-time multi-master high-speed bus. Background technique [0002] In the safety system design, bus communication needs to meet several basic requirements: electrical isolation between different nodes, high-speed communication between different nodes, real-time communication between different nodes, fault tolerance and fault isolation between different nodes. [0003] There are a variety of bus mechanisms in the industry, but none of them can fully meet these requirements, for example [0004] 1. The high-speed parallel bus can meet the real-time requirements, but cannot meet the isolation requirements between different nodes; [0005] 2. Network communication can meet the isolation requirements, but cannot meet the real-time requirements; [0006] 3. The CAN bus meets the requirements of isolation and real-time performance, but cannot r...
