基于飞机着陆下滑引导监视系统设计需求,针对现有光电经纬仪通信的缺陷,通过分析系统通信物理链路,突破了光电经纬仪之间通信转换协议设计、查表法CRC码校验快速计算、实测数据滤波模型构建等关键技术,以软件技术代替硬件板卡信号处理,实现了稳定可靠且成本低廉的飞机着陆下滑引导监视系统,实验部分验证了该方法的有效性。目前,该系统已成功应用到某型飞机灯光着陆系统试飞中。
Aiming at the defects of the existing optical theodolite communication based on the design requirements of the aircraft landing gliding guidance and monitoring system, by analyzing the system communication physical link, the design of the communication conversion protocol between the theodolite is broken through. The fast CRC table check calculation and the measured data Filter model construction and other key technologies, software technology instead of the hardware board signal processing, to achieve a stable and reliable low-cost aircraft landing glide guidance and monitoring system, the experimental part of the verification of the effectiveness of the method. At present, the system has been successfully applied to a type of aircraft lighting landing system test flight.
