Central alarm verification method under comprehensive modular avionics architecture

Abstract

The invention belongs to the field of avionics systems, and provides a central alarm verification method under a comprehensive modular avionics architecture. The central alarm verification method comprises the following steps: S1, enabling the system to have a fiber channel network node simulation capability; S2, enabling the system to have the capability of simulating flight state information andwarning information of all airborne optical fiber channel network nodes; S3, connecting a simulation excitation system with a certain standby port outside the airborne fiber channel switch to realizephysical connection between the system and the airborne network; S4, compiling a network configuration file according to an airborne network configuration file compiling rule so that the system has amessage transmission capability; S5, simulating a plurality of pieces of alarm information of different alarm levels in a certain non-alarm-suppression flight state, and correspondingly checking alarm display, voice and light processes; and S6, simulating different flight state information to drive to generate different flight stages, simulating a plurality of pieces of alarm information as required in each flight state, and correspondingly checking suppression processing results of different flight stages.

Description

technical field [0001] The invention belongs to the field of avionics systems and relates to the verification of a central warning system, in particular to the verification of the central warning system under the framework of a general modularized avionics system. Background technique: [0002] The central alarm system is a system capable of receiving alarm information from each subsystem / equipment of the aircraft, sorting the alarm information according to the alarm level and priority, and driving the display, voice and light alarms after judging that the alarm information is valid. At the same time, the central warning system can suppress the warning according to the design requirements on the basis of obtaining the flight status information, so as to reduce the burden on the pilot. [0003] Based on the rapid development of avionics systems and the goal of weight reduction, avionics systems have gradually adopted a generalized modular design. The traditional alarm process...
