Self-adaptive multi-path serial redundant high-speed bus

Abstract

The invention discloses bus equipment, comprising two composition structures and sub equipment including a forward subsystem and a backward subsystem, wherein the two composition structures are used for transmitting data in two transmission directions; the forward subsystem and the backward subsystem have the same connecting relationships; the forward subsystem comprises a forward input saving module, a forward transmitting module, a forward receiving and saving module, a forward output module, a forward feedback control module and a forward instruction control module; and the backward subsystem comprises a backward input saving module, a backward transmitting module, a backward receiving and saving module, a backward output module, a backward feedback control module and a backward instruction control module. The bus equipment can simultaneously realize the work with high speed and high reliability and the capacity of bus nodes is higher.

Description

technical field [0001] The invention relates to computer communication technology, in particular to a bus device. Background technique [0002] In modern military technology, the number of electronic devices on weapons continues to increase. How to effectively integrate electronic devices to achieve the integration of resources and functions has become an urgent requirement for weapon development. The basis of the weapon's integrated electronic system is to adopt the data bus structure, and use the data bus to make the three subsystems of processor (including hardware and software), information transmission and control display shared by various tasks. In order to achieve the purpose of reducing the volume and weight of weapon equipment, improving the reliability of weapon systems, reducing costs and improving detection accuracy. [0003] At present, the bullet (arrow) bus basically adopts the common 422 bus, and the newly promoted ones include 1553B bus, CAN bus, field Fast...

AI Technical Summary

Problems solved by technology

[0011] 3) The 422 and LVDS buses have no timing constraints, let alone protocols, and are the most convenient to use, but the bus itself has no reliability guarantee mechanisms such as error correction and retransmission, and its working stability needs to be guaranteed by the system. Therefore, if it is directly applied, its stability Sexuality cannot meet the requirements of military scenarios;

However, in this scheme, if the current bus does not have a problem, the backup bus will always be idle and cannot be fully utilized; and even if it is a dual backup, both buses may still fail, and communication will still fail at this time;

[0013]5) The capacity of bus nodes is small

[0014] It can be seen that the existing bus technology cannot realize high-speed and high-reliability work at the same time, and the capacity of bus nodes is limited, so it cannot adapt to the multi- Communication requirements for each device
