Design And Implement Of LDS High-End Simulator System Of Interface

The simulator application is more and more widespread in different field. With the development of computer and simulation technology, it is possible to increase the function and improve the quality of the simulator. In the engineering, the simulator which is implemented with physics effect equipment in computer and every special tools is one kind of large-scale computer system simulation technology making use of system model to dynamic research into real or the imaginary system. Specially, the high-end simulator is the true system integration. It incorporates the simulation technology, computer technology, software development, communication technology, automatic control, image processing, audio frequency technology and machine manufacture.This paper is based on the LDS simulator project which is developed for Iran National Railroad Bureau by the Beijing Xinyuan company. Firstly this paper the presents situation and the significance of simulator , then introduce the LDS simulator function needs, thirdly, the paper analyse the needs of the LDS simulator interface system data,. The paper designs the data acquisition and implement the program. Finally, the paper concludes the LDS interface system of the LDS simulator. and discusses the further improvement and the development of LDS simulator and it' s interface.
