Method and device for integration of control system software of aircraft engine

Abstract

The invention provides a method and device for integration of system software of an aircraft engine. The method comprises the steps that the to-be-integrated control system software runs on a virtualhardware platform to constitute a controller assembly; through an interface adaptive assembly, the controller assembly is connected to a model simulation assembly; on a man-machine interface which runs monitoring and injection of the assemblies and provides software testing, a testing instance is read and sent to a running control assembly, adjustable parameters are read and sent to the controllerassembly, and running data of the control system software is received; testing courses of the control system software is controlled in the running control assembly; and behavior features of a controlled object are simulated in the model simulation assembly, and a closed loop simulation environment is provided for testing of the controller assembly.

Description

technical field [0001] The invention mainly relates to software testing and integration of an aeroengine control system, in particular to an integration method and device for aeroengine control system software. Background technique [0002] At present, the mainstream control technology of aero-engine adopts numerical control system, that is, full authority digital electronic control (FADEC), in which the control software is the core. After completing the design of the control logic model, the engine control software performs simulation verification, automatically generates codes or manually implements the control logic codes, and further integrates with other related codes to form operable software, such as task scheduling, communication, acquisition, signal processing, signal output, etc. The control software development process in the prior art is: after simulation at the model level, use the same hardware device as the peripheral interface environment of the electronic c...

Problems solved by technology

[0003] 1) Model simulation requires the use of a modeling tool license. When multiple people work together, the cost of purchasing a modeling tool license is high; modeling tools are aimed at use case loading, operation control, data storage, and test automation related to software debugging The support is limited, the secondary development is difficult, and the cost of technical consultation from the original manufacturer is high; in addition, using the modeling tool environment for model simulation also has the problem of slow simulation speed and low efficiency for large-scale simulation operations;

[0004] 2) The overall software integration work depends on the development of the hardware platform. When the hardware platform is not in place or the resources are insufficient, the overall software integration and testing work cannot be carried out; due to the long development cycle of the hardware platform, the overall software integration can only be carried out after the hardware platform is in place. Integration, the cost of finding and solving problems is greatly increased;

[0005] 3) The model simulation work and the software and hardware integration work are in a state of separation, the model simulation use cases cannot be inherited in the software and hardware integration link, and the test cases still need to be newly designed in the software and hardware integration verification link, resulting in a waste of human resources; model-level simulation results and The storage format of the simulation results of software and hardware integration is inconsistent, which brings additional workload for later data analysis and increases the cost of software integration
