中国铁路信号显示技术的回顾与展望

信号显示是信号所能表达意义的总称,包括地面信号显示和车载信号显示。以发展为脉络,首先介绍地面色灯信号的颜色、机构、显示含义的发展过程,阐述地面信号"速差制"显示制度形成的重要原因。分析不同类型信号机构之间兼用的可行性,描述灯光配列原则与机构外形的变化,进而讨论地面信号显示制式应用的局限性。然后介绍车载设备、列控系统的发展,阐述车载信号显示制式的显示方式、内容,并分析其与地面信号显示制式之间的关系。结合不同等级列控系统的特点,讨论车载信号显示制式在部分等级应用的局限性。最后展望信号显示制度的宏观发展方向,初步探讨CTCS-1、CTCS-4级及ATO列控系统信号显示技术特点。下一代列控系统在向着自动化和智能化方向发展,届时信号显示含义也将重新定义。

Retrospect and Prospect of Chinese Railway Signal Display

Signal display is a general term for the meaning that a signal can express. It includes ground signal display and vehicle signal display. The development processes of the color, the mechanism and the meaning of signal aspect and indication are introduced and the formation of elementary speed signaling is demonstrated. The compatibilities of different types of ground signal are analyzed, the changes of light shape and arrangement are described, and the limitation of ground signal display system is discussed. The development of on-board equipment, train control system, display mode and content of vehicle signal is then introduced. The relationship between vehicle signal and ground signal is analyzed, and the limitations of vehicle signal display system applied in some grades are discussed combined with characteristics of different grades of train control system. Finally, the development direction of signal display is prospected, and the signal display of CTCS level one, four and ATO system is studied. The next generation train control system would develop towards automation and intelligence, and the meaning of signal display would be redefined.
