摘要
针对目前飞机重心调控系统通信部分存在的干扰问题,采用汉明码纠错技术对发送和接收数据进行纠错校正。本文将繁杂的汉明码算法简单化,便于程序编程的实现。为了不影响通信的速率和系统的实时性,采用查表的方式对汉明码进行编程。实验证明:在加入了汉明码纠正技术后,通信稳定可靠,重心调控系统运行实时性高,完全符合飞机的试飞要求。
To solve the current problems existing in communications of the barycentre of plane automated modulate system, Hammingeode correcting technical is used in the dam＇s sending and receiving. Besides, this paper simplifies complicated hamming method, which is conducive to the realization of programming. In order to not a[fect the rate of communications and real-time of system, harnmingeode is programmed through the look-up table. The experiment shows that this system could run stably and has a good behave in real-time, and the requests of test flight of new planes have being achieved,since the hamlningeode correcting is used.
