在未来战争中通信卫星将是首先被攻击的目标,中、远距离军用机功通信将仍然依靠短波无线电台来保障。为了提高短波通信的可靠性而注视自动链路技术的研究,国内外已发表不少文章,但未提出标准化方案。本文提出按1986年颁布的“国家军用标准 GJB89—86数据链路控制规程”设计实现链路信令的方法,使有微处理器控制的短波电台能实理自动链路。本文介绍自动扫描、锁定的链路过程;详细介绍按 GJB89—86数据链路控制规程设计链路信令的方法;提出详细的实现信令传输的程序框图;最后给出链路建立和维持的过程图。文中对主要程序段用微机模拟调试过。本文为微机控制的无线电台设计与应用也为无线电台加入统一的数据网提供解决前提条件的方法。
In the future war, communications satellites will be the first target to be attacked. Medium- and long-range military communications will still rely on short-wave radio stations for protection. In order to improve the reliability of shortwave communications and watch the automatic link technology research, many articles have been published at home and abroad, but did not propose a standardized solution. In this paper, we propose a method of designing link signaling according to the “National Military Standard GJB89-86 Data Link Control Rules” promulgated in 1986 so that the shortwave radio controlled by the microprocessor can handle the real-time automatic link. This article describes the automatic scanning, locking the link process; details of the GJB89-86 data link control procedures designed link signaling method; put forward a detailed signaling diagram of the block diagram; Finally, given the link to establish and maintain Process diagram. The main text of the program with computer simulation debugging. This article for the design and application of computer-controlled radio stations for radio stations to join a unified data network to provide ways to solve the preconditions.
