Based On The File Parsing Aircraft Simulation System Software Design

The aircraft simulation system is an important component in the process of development and operation of sophisticated aircrafts. Through simulation of the input/output interface of a real aircraft, data consistent with a real system is produced. And using simulated data can effectively avoid the probably high risk of using a real aircraft, which in turn greatly improves the development, testing and operational efficiency of ground control system.This thesis demonstrates the development methodology of the software for the aircraft simulation system based on file parsing. This design can implement easy changes in functionality via simple editing of configuration files when modification of the hardware or software source code is infeasible. In this way, the versatility and scalability of the system are greatly improved.The major works of the thesis are listed as follows:a) Initialisation profile for Ethernet interface chip W5300and1553B interface chip BU-61580for the hardware platform of the simulation system is given besides detailed introduction of settings for each register;b) Multi-task management mechanism based on time slices is implemented using the DSP timer, enabling the system to execute multiple tasks in real time without an operating system;c) FatFs is ported to the hardware platform of the simulation system, with the means of reading and parsing data for configuration files presented;d) Data transmission protocals for Current-Loop, RS422,1553B and Ethernet are formulated with detailed implementation introduced;e) The processing method for the two types of switch signal (logical and control code signal) is given.
