Study on Testing Platform for Train Control Center——Simulation of Communication Sub-System
HU Tian-yi · Computer Technology and Development · 2008
The testing platform for train control center is designed to test and access the reliability and safety of the train control center system.As one part of the platform,the sub-system of communication simulation accomplishes the data exchange between the train control center and the platform.With the application of object-oriented modeling and multithreading serial communication techniques,the simulation of communication sub-system is established.The interface mode and the communication protocols between the platform and the object tested are discussed in detail in this paper.The example given at the end of this paper shows that the simulation sub-system has met the demands of the platform.
