【Abstract】 With the wide application of computer. The computer simulation technology has been rapidly developed. It is playing an increasingly important role in social economy system, military science research system and educational service system etc. The training simulation system studied and designed by this paper is a totally new application of computer simulation technology in education area.This paper analyses the feature, technology, performance of synchronous digital hierarchy which is the new fiber communication hierarchy, and discusses the general structure, function module of the simulation system based on the computer. This paper also gives a new method on the hard section of the auto searching signal in the failure system. In this paper, a mathematical method is utilized to describe how to get a general model of the telecommunication equipment based on training aim. Author analyses and gives the data model and the arithmetic model of the SDH fiber communication training simulation system integrated database-modeling technology.The simulation system of SDH fiber communication for training service on the microcomputer platform is designed with the methods discussed by the paper above, The flexible design and powerful function have greatly simulate the truly communication system in the interface, the state of the action and the feedback of the system, this system can assume the role of the training and test of the staff, the system’s successful complication will greatly improve the training condition and will stir the progress the staff.更多还原
