An Electromechanical Management Redundancy System Based on Data Flow

Abstract

The invention belongs to the technical field of airborne electromechanical management subsystems, and particularly relates to an electromechanical management redundancy system based on a data flow, which comprises dual channels in mutual redundancy. Each channel is internally provided with an external bus communication module, a channel data storage area, a channel data transmitting module, an other channel data storage area, an automatic transmitting module, an automatic receiving module and a main engine interface module. through using the system, when a certain functional part in one channel fails, fault isolation is carried out, and functions of the system can be ensured to be completed smoothly; when intersected fault happens between the dual channels, resource recombination is carried out on a health functional module, data intersected sharing and intersected control can be realized, and the functions of the system are completed; and the system has strong real-time performance, and an overall set of control process from data acquisition, data processing, instruction output and the like can be completed in a period.

Description

technical field [0001] The invention belongs to the technical field of airborne electromechanical management subsystems, and in particular relates to an electromechanical management redundancy system based on data flow. Background technique [0002] In the aircraft electromechanical system, the electromechanical management subsystem is an important part. Its reliability and performance directly affect the safety of the electromechanical system and even the entire aircraft. According to this demand, the electromechanical management subsystem is required to have high safety and reliability. At the same time, as the integration degree of the electromechanical management subsystem has been greatly improved, the electromechanical management subsystem has integrated braking, power supply and other systems that have high real-time requirements, which requires the electromechanical management subsystem to have high real-time processing capabilities. According to these characteristic...

Problems solved by technology

[0003] The traditional dual-redundancy design is generally more complicated, and the real-time performance is poor, and the processing of the redundancy data cannot be completed in this cycle. It is urgent to design a new set to realize the data sharing between the dual-redundancy and the failure after a single point of failure. Data reorganization and cross control can be performed after isolation and cross faults, and a complete control process from data collection, data processing to command output can be completed in any task cycle, and it has a redundancy management system with strong real-time control
