【摘要】 车站列控中心测试平台是对列控中心系统进行可靠性、安全性测试及评估的平台。通信仿真子系统是平台的一个子系统,它主要实现被测对象与平台中相关模拟子系统之间数据的交互。采用面向对象的多线程串口通信技术对通信仿真子系统进行了研究。详细地阐述了测试平台与被测对象之间的接口方式与通信协议,并给出仿真实例,满足了平台对通信仿真子系统的要求。更多还原

【Abstract】 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.更多还原
