摘要
集中式25 Hz相敏轨道电路是近年来新兴的一种站内轨道电路制式,设备集中室内设置,实现了集中调压/调相,具有结构简单、维护方便以及抗干扰能力强的特点。本文采用四端网络理论,建立集中式25 Hz相敏轨道电路调整态的基本数学模型,利用MATLAB软件中的GUI设计,生成参数仿真结果及系统调整表,以此作为该系统调整及维护的理论依据。
The centralized 25 Hz phase-sensitive track circuit is an emerging in-station track circuit system in recent years,which adopts centralized installation of indoor equipment to achieve centralized voltage adjustment and phase adjustment and is characterized of simple structure,convenient maintenance and strong anti-interference performance.This paper adopts four-terminal network to establish a simulation model for state adjustment of the centralized 25 Hz phase-sensitive track circuit and uses the GUI design tool of MATLAB software to export the simulation results of system parameters and generate an state adjustment table as the basis for system adjustment and maintenance.
