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.
