摘要: 为了实现多种传输速度和数据格式信号的光纤传输,开发了基于串口通讯的点-点链路光传操纵技术.以直升机飞行控制系统为背景,构建了飞行控制系统的地面光传半物理平台,建立了显模型计算机与飞行控制计算机之间、飞行控制计算机与实物舵机之间的通信.光/电传试验仿真表明,所开发的显模型跟踪光传系统LED(发光二极管)的中心波长为820 nm,最大传输距离400 m,远大于实际需要的光纤长度;飞行状态能准确地跟踪显模型输出,跟踪度不小于90.11%.Abstract: In order to achieve the fiber-optical communication with different speeds and data formats,a fly-by-light point-to-point link scheme based on serial communication was proposed.By taking the flight control system of a helicopter as an example,a semi-physical simulation platform was constructed,including communication between the MFCS(explicit model-following control system) computer and the FCS(flight control system) computer and communication between the FCS computer and the actuator.The simulation results show that the center wavelength of LED(lighting emitting diode) of the fly-by-light scheme is 820 nm,the longest transfer distance is 400 m far beyond the practical requisition,and it can track more than 90.11% of the input.
