摘　　要：利用RTLinux系统RTFIFO的实时性和共享内存,设计并实现基于RTLinux的飞控系统的进程间通信方案。采用多种通信机制相结合的方法,解决飞控系统内部复杂的进程间通信问题。实验结果表明,该方案能够满足系统对实时性能的要求,保证通信效率的稳定可靠。This paper designs and implements the inter-process communication of the flight control system based on RTLinux. According to the design task, with the good performance of the real-time FIFO provided by RTLinux and the advantage of reducing data copying of the shared memory, considering the efficiency of real-time requirements, it combines several communication mechanisms. It solves the issue of complex inter-process communication in the flight control system, and metes the demand of both real-time and efficiency.
