【摘要】 本课题以开发“莫尔斯码自动化标图系统”为背景,对自动标图上位机系统进行了一定程度的分析研究,重点对信息处理模块中莫尔斯码数据纠错部分进行了详细设计。本文首先描述了莫尔斯码标图的现状和发展趋势,说明了研制莫尔斯码自动化标图系统的意义,介绍了作者的主要工作及本文的组织结构。本文对莫尔斯码、数字化地图、九九方格坐标和大地坐标相关概念进行了介绍。在此基础上,概述了莫尔斯码自动化标图系统的主要功能及组成。该系统分为莫尔斯码自动解读下位机分系统和自动标图上位机分系统。上位机分系统的主要功能是空情标绘和空情模拟。空情信息标绘部分负责对信号进行识别、排错、分类和存储等处理,并且实现自动化标图。目标信息标绘部分组成主要有制定密语表模块、开设指挥所模块、接收模块、处理模块和自动标图模块。空情模拟部分由编辑空情模块、波形转化模块和音频播放模块组成,它用来对空情进行仿真模拟,达到平时进行相关训练的目的。针对各种干扰及人为失误易导致空情数据错误的事实,作者重点对该系统数据纠错处理部分进行深入研究。论文详细阐述了信息处理模块中数据纠错部分的分析与设计。数据纠错作为航迹标绘的前期准备,是整个系统实现正确空情标绘的关键之一。文章总结了空情数据组的十种正确编组格式。分析了莫尔斯码错码会形成数据冗余、数据残缺和数据变异等三种错误类型。针对这些错误情况,文章给出了数字莫尔斯码分解纠错法、坐标错误的距离判断法、缺失坐标的BP网络预测法、数据组内部数据数目判别法和数据组自身特征纠错法等五种数据纠错方法。在附录中给出了莫尔斯码表。本文在总结中给出了已有工作总结,谈到了尚需进一步解决的问题及下一步的研究工作内容。

【Abstract】 Based on the background of developing the Morse code automatic plotting system, the top device system of the automatic plotting is analyzed at a certain degree. The Morse code data error correction of the information processing module is detailed designed in keystone.The present situation and the development tendency of the Morse code plotting are first described. The necessity and the feasibility of the Morse code automation plotting system are explained. Author’s main work and the organizational structure of this article are introduced.The concept of Morse code, the digitized map, nine—nine pane coordinate and the geodetic coordinate are introduced. In this foundation, the Morse code automatic plotting system main function and its composition are outlined.The Morse code automation plotting system is divided into the top device subsystem and the down device subsystem. The top device subsystem has two basic functions: Air situation drawing and air situation simulation. The air situation drawing is responsible to recognition, correction, classification, storage and so on. It also realizes automatic plotting. The air situation drawing is mainly made up of the cipher table module, opening the headquarters module, the receiving module, the information processing module and the automatic plotting module. The air situation simulation is marked up of the edition air situation module, the wave transformation module and the audio frequency broadcast module. It is used for the air situation simulation, achieving the goal of the training.Aiming at the fact that the kinds of disturbance and the artificial fault are easy to cause the air intelligence data error, data error correction is studied in keystone. Analyses and the design of the data error correction in the information processing module are elaborated. As the earlier period preparation, the data error correction is the key of realizing air situation drawing. Ten kinds of the air situation data grouping form is summarized in this article. The mistake of the Morse code can make three kind of wrong types. They are the lacking data, the excessive data and the variation data. The digital Morse code analyzing method, the coordinate distance judgment method, BP neural network forecast method, the data number in group judgment method and the data group characteristic judgment method are proposed.The Morse code table is offered in the appendix. The question that should be solved and the content of the next work are given in the end of the article.
