随着高速铁路的发展,列车运行自动控制设备水平也在不断提高,数字化、无线传输技术、漏泄电缆及卫星定位技术实现了列车和地面控制中心、列车和列车之间的信息传输,列车之间通过数据传输,自动计算出实时的列车追踪安全间隔,调整之间的追踪间隔,使两列车间的间隔最小,从而提高了行车密度和区间通过能力,这种运行间隔称为移动自动闭塞,代表了区间闭塞技术的发展方向。目前,我国自行研制的以数字信号处理技术为基础的新型移频自动闭塞系统即ZPW-2000A已被广泛应用。本文就对ZPW-2000A系统工程设计及维护进行了探讨。
With the development of high-speed railway, the level of automatic control equipment for train operation is also increasing. Digital, wireless transmission technology, leaky cable and satellite positioning technology enable the transmission of information between trains and ground control centers, trains and trains. Between trains Through data transmission, the real-time train tracking safety interval is automatically calculated and the tracking interval is adjusted so as to minimize the interval between two trains so as to increase the driving density and the interval passing ability. The running interval is called automatic moving blocking and represents The development of interval occlusion technology. At present, ZPW-2000A, a new type of automatic frequency-shift blocking system based on digital signal processing technology developed by our country, has been widely used. This article discusses the ZPW-2000A system engineering design and maintenance.
