Design And Realization Of The Mutual Guidance Software Of TT&C Equipment

The distributed networking technology of range TT&C(Tracking,Telemetry,and Control)equipment can effectively enhance the flexibility and fault tolerance of TT&C system,shorten the preparation time of emergency tasks,so as to adapt to the future high-density,consistent,multi-target and multi-jamming situations.Until now,the range TT&C network adopts the centralized command-and-control mode of control centre which makes the software structure hard to understand and maintain,thus it can not take full advantages of flexibility and fault tolerance of distributed networking.This article develop the mutual guidance software,which effectively resolve the problem of centralized command mode.At the beginning,the article introduced the concept,the significance and the present developing situation of distributed networking technology,analyzed the working mechanism including the networking principles and forms.Then we elaborated the basic principles of mutual guidance technology which included data transmission mode,data formatting convention,coordinate transformation method,data preprocessing and UKF filtering technology.We described the design and implementation process of data communication software,tested the software and analyzed typical applications of distributed networking technology in missile test range from July 2017.The main research results of this dissertation are as follows:1.According to the software engineering method,the requirements analysis,software design,software implementation and software test of mutual guidance software are completed,and the software products that can be directly used in range TT&C equipment are produced.2.The mutual guidance technology is an effective supplement of centralized command mode,which can make full use of distributed networking’s advantages.3.The mutual guidance software developed in this paper can be generalized in similar units.4.According to the testes in many tasks,it can be seen that the network mutual guidance between TT&C equipments is achievable,when the center is unable to guide.
