摘要
铁路区间信号系统测试评估平台的研究是为了实现对信号系统的功能、可靠性及安全性的自动测试和评估,并为区间信号系统的研发或维护提供测试手段.铁路区间信号系统信息传输通道,作为铁路区间信号传输的途径,是铁路区间信号系统测试评估平台的重要研究对象,因此,信息传输通道仿真子系统是测试平台的一个关键子系统.针对移频自动闭塞系统信息传输通道的仿真,提出一种新的差分方程建模方法,并进行了仿真实现.
Research on the testing and assessment platform of railway section signal systems is to build an automatic checking and measuring device to test and assess the security and reliability of railway section signal equipments, and to provide means for studying and developing new section signal systems and keeping railway section signal equipments in a good condition. As a virtual channel for information transmission, the simulated transmission channel subsystem is playing an important role in the testing and assessment platform. The modeling method of the transmission channel, based on difference function, is put forward and discussed, and the model is simulated with the MATLAB language.
