摘要
为克服现有列车自动运行系统中输出方式信号种类不全的问题,设计一种可提供数字量信号、电压模拟量信号、电流环信号以及PWM信号的输出单元。本系输出单元与对系输出单元互为冗余,均包括:数字量输出模块、模拟量(电压和电流环)输出模块、PWM输出模块、以及CPU模块。数字量信号、电压模拟量信号、电流环信号以及PWM信号能够进行一种或多种组合输出。满足现有各种型号列车自动运行系统对输出信号的需求。
In order to overcome the problem of incomplete types in the existing automatic train operation system, an output unit which can provide digital signal, voltage analog signal, current loop signal and PWM signal is designed. The output unit of this system and the output unit of the other system are mutually redundant, including digital output module, analog output module (voltage and current loop), PWM output module and CPU module. Digital signal, voltage analog signal, current loop signal and PWM signal can be output in one or more combinations. It can meet the demands of all kinds of automatic train operation system for output signals.
