Data transmission method for dual redundant systems based on high-speed serial buses

Abstract

The invention belongs to a practical technology in the field of an airborne electromechanical management subsystem and is mainly applied to design and implementation of dual redundant systems in airborne equipment. The data transmission method for the dual redundant systems is simple, the dual redundant systems are cross-linked through high-speed buses, all data can be transmitted in real time, data received by the system are autonomously transmitted to the opposite channel while being received, and the data to be transmitted by the systems are mutually transmitted in real time through a datatransmission module between the two channels, thereby ensuring real-time update of the data between the dual redundant systems. When individual signal failures occur in a single channel, each channelis enabled to obtain complete correct data through data integration between the two channels; when functional component failures occurs in a single channel, data calculation is completed by the normalchannel through failure isolation; and when the process of a single channel fails, the opposite channel can complete system functions through cross data control.

Description

1 technical field [0001] This technology is a technology in the field of airborne electromechanical management subsystems, and is mainly used in the design and implementation of dual redundancy systems in airborne equipment. 2 background technology [0002] One of the important components of the aircraft electromechanical system is the electromechanical management subsystem, whose reliability directly affects the safety of the electromechanical system and even the entire aircraft. In the context of this demand, the electromechanical management subsystem is required to have high safety and reliability. sex. Due to the further improvement of the comprehensiveness of the electromechanical management subsystem, the electromechanical management subsystem integrates braking, power supply and other systems that have high safety requirements, which requires real-time and complete data transmission between the dual redundancy of the electromechanical management subsystem and autonom...

Problems solved by technology

[0003] The traditional data transmission set between dual redundancy, the general data interaction is slow, requires processor intervention, cannot be completed independently, all data cannot be interacted in real time, and cross control cannot be realized between dual redundancy, etc.
