Design And Implementation Of Simulation System Of Chart Plotting Platform Based On Qt

System simulation is a comprehensive science that research system characteristics on aexisting or developing system. If the actual system does not exist or cannot be directlyresearched on, the only way to research the system is to structure a system structure modelwhich can both reflect the characteristics of the system and meet the requirements of thesystem research.Realizing a simulation system based on the system structure model，throughthe simulation system we can reveal the inherent characteristics and operation rules of thesimulated system and predict the future system performance parameters.With the development of simulation technology, simulation science tends to bediversified and comprehensive. Initial simulation technology is used as a auxiliary tool foractual system in system test. Now the application of simulation system include: systemconcept study, feasibility study, systems analysis and design, system development, system testand evaluation, operator training, system forecast, system use and maintenance of all aspects,etc. Its application field has developed to the military, and every important areas related to thenational economy.Chart plotting platform system is a set of mechanical and electrical integrated navigationequipment that use full digital plotting operation technology. It realized paper chart digitalplotting operation with the developing of microelectronics technology, embedded computertechnology and object-oriented theory, the existing system design and realization methodmust be changed to significantly improve the modular degree, software reliability, portabilityand easy maintenance of chart plotting platform system.This topic virtually design the newgeneration chart plotting platform system based on a certain type of chart plotting platformsystem in Qt Creator, a Qt integrated development environment.Goal is to develop a set ofstable and reliable simulation system of chart plotting platform with friendly user interfaceand highly modular, at the same time to realize the system’s convenient transplantation in avariety of operating systems.First of all, present the overall design scheme of the new generation chart plottingplatform system with the research of the existing system structure, working principle and areference to the domestic and foreign relevant material. On the basis of above, design eachmodule of simulation system of chart plotting platform with the understanding of the originalequipment deficiencies.In the design process, firstly study data communication, data storage and processing method of the simulation system, secondly clear the function of each module, at last give theinternal structure and function of joint of each module.Secondly, given the communication method between system modules with a reference ofQt’s characteristics.then programming each module in Qt Creator to realize its internalstructure and function.Finally, give the program release method in Qt Creator and release the simulationsystem.
