信号系统与跨座单轨道岔转辙器接口设计

Design of Interface between Signal System and Switch Machine of Straddle-Monorail

跨座式单轨交通是城市轨道交通制式中较为特别的一种形式,具有适应性强、噪音低、转弯半径小、爬坡能力强等特点。跨座式单轨道岔集导向和承重于一体,是有一定长度的道岔梁,一端可以移动,每片道岔梁均固定在一个支撑台车上,由台车上的道岔转辙器驱动。道岔转辙器控制指令来自信号系统,经信号系统判断道岔转辙器具备转动条件时,信号系统会输出转辙器动作命令,转辙器依靠自身驱动装置转动。信号系统与转辙器的接口设计须符合故障-安全原则,接口设计安全,可靠。

The straddle-monorail is a special form of urban rail transit system, which has the characteristics of strong adaptability, low noise, small turning radius and strong climbing ability. The straddle-monorail switch integrates a set of orientation and load-bearing by a certain length of the track beam, and its one end can be moved, each piece of track is fixed on a support trolley and driven by switch on the trolley. The signal system determines the movement of the switch, and will output a switch action command if the condition is met, then the switch will turn by itself. The design of the interface between the signal system and switch should conform to the fail-safe principle and must be safe and reliable.
