C919机载数据实时处理系统设计

对于无人机在输电线路杆塔精细化巡视的路径规划问题，提出了对杆塔巡视路径和杆塔间避障路径的两阶段优化策略。针对利用传统旅行商问题(TSP)求解杆塔巡视路径，在多项式时间无法求得全局最优解问题，研究了基于双调欧几里得TSP求解杆塔最优巡视路径的优化数学模型，以及基于动态规划算法的求解方法。在此基础上，进一步基于人工势场法建立了避开巡视路径障碍最优路径的优化模型及其求解方法。仿真结果表明，利用双调欧几里得TSP确定的巡视路径具有偏转角小、最优路径求解时间短的特点，利用所提两阶段优化策略确定的巡视路径长度较短且能有效避开障碍，有利于实现无人机安全高效巡视杆塔的目标。

Design of C919 Airborne Data Real-time Processing System

Airworthiness certification is a key link in the development of large aircraft. Flight test is an important basis for the implementation of airworthiness certification tasks. Throughout the flight test of large aircraft at home and abroad, real-time processing of airborne data is very important. The real-time processing system of airborne data is studied in C919. Based on VXWORKS embedded real-time operating system, the performance of C919 airborne data real-time processing system is improved by integrating the function modules of the existing airborne real-time processing system and optimizing the software design. Flight validation shows that the system can receive, store, process, forward and process the 110 MB/S network data in real time. Compared with the traditional design, it can better ensure the real-time processing of system data, and provide technical support for ensuring the safety of large aircraft flight test and improving the efficiency of flight test.
