城市轨道交通信号与通信系统基础知识(国外英文资料) Basic knowledge of urban rail transit signal and communication system Completion Urban rail transit signal system usually includes two parts, interlocking device and automatic train operation control system respectively. The automatic train operation control system (ATC) includes ATO (train automatic driving), ATP (automatic train overspeed protection) and ATS (automatic train monitoring system). The signal machine is composed of a column, a mechanism, a bracket, a ladder and a foundation. (this means a high column signal, if there is no ladder in a short signal.) Mechanism is composed of a lens group (focusing effect), lamp holder, lamp (bulb placed) (Guang Yuan), the chassis (installation of components), the marquee (avoid other light) and back (brightness increases color light signal and the surrounding background). A lens type signal is a device made up of the color and number of signals and uses a lens set of optical material. Through the display of color lights, train operation conditions are provided, and a series of display devices are called signal machines. The signal machine according to height can be divided into high signal and low signal machine. The signal machine can be divided into protective signal machine, blocking signal machine, out section signal machine, incoming signal machine and shunting signal machine according to different function. The signal set in the switch section is called a protective signal machine. 10. The equipment that controls the speed of the train entering and moving is called the signal. The transmission of various information (images, information, etc.) is called communication. 11 、 relay is composed of electromagnetic system and contact system. The electromagnetic system consists of coils and cores, that is, the input system. The contact system consists of front contacts and rear contacts, i.e., the output system. 12. The functions of the switch machine include switching the switch and locking th
