座舱信号采集系统是飞机模拟器的重要组成部分,座舱内的开关,按键,指示灯等是飞行员和飞机之间的主要交互设备。由于座舱信号采集系统的实时性和稳定性等原因,其实现方法一直是飞机模拟器的难点之一。通过对现代数据采集技术的研究,提出一种基于I2C总线的座舱信号采集系统,该系统通用性强、体积小、成本低,使用维护方便。
Cockpit signal acquisition system is an important part of the aircraft simulator, cockpit switches, buttons, lights and other pilots and aircraft are the main interaction between devices. Due to the real-time and stability of the cockpit signal acquisition system and other reasons, its implementation has been one of the difficulties of the aircraft simulator. Based on the research of modern data acquisition technology, this paper proposes a cockpit signal acquisition system based on I2C bus, which has the advantages of high versatility, small size, low cost and convenient operation and maintenance.
