区域联锁传输通道的安全性问题及仿真

Safety and Simulation of Area - interlocking Transmission Media in Testing Platform

构造了区域联锁系统测试平台的框架模型,并给出了在模型中承担信息传输的载体(光纤)的选择。传输过程是一个连续和离散相结合的过程,作者选用Petri网对传输过程进行仿真建模,同时还给出了仿真系统的模块图。

By making a framework model of area - interlocking system testing platform, which provides the choice of the media(optical fiber) for information transmission, the author uses Petri Net as the tool to set the simulation model, because transmission procession is a union of continuous procession and discrete procession, and thus produces the module picture consequently.
