仿真转台计算机控制系统设计与实现

Design and Realization of Simulator's Computer Control System

计算机控制系统是保证仿真转台功能和性能的重要部分 ,文章结合飞行仿真转台讨论了计算机控制系统的设计问题 ,比较了单机集中控制、多机集散控制等几种不同结构形式的转台计算机控制系统方案 ,并以某型仿真转台为背景 ,采用DCS机制设计了计算机控制系统 ,对系统工程实现中的接口线路设计、采样频率选取、程序设计等一系列关键问题进行了讨论 。

Computer control system is an important part for guarenteeing performance of the simulator. In the paper some problems about overall design and realization of a computer control system of a turntable are presented according to the flight simulator. Some schemes of the simulator's computer control system with different structure forms are compared. For example: single-computer control,multi-computer distributed control and etc. Then taking a certain flight simulator as background,the whole series of key problems such as the interface circuit design, selection of the sample frequency and the program design for the control and management in the design and realization of computer control system are discussed respectively, and the design scheme is successfully applied in a simulator.
