列车上水自动控制系统设计

Automatic Control System Design of Train Water-feeding

针对列车上水自动控制系统中电磁阀关断的阀值(水箱水满判据)确定问题,基于组态软件开发设计了一个自动控制系统.系统的工作分为手动训练阶段和自动控制阶段,在手动训练阶段,电磁阀的开断由人工手动控制,系统自动记录当时的水压数据,经过一定时间的训练,系统可进入自动控制阶段.此系统可采集不同复杂环境下关电磁阀时的水压数据,在理论数据的基础上,利用实验数据来优化水箱水满判据,使上水电磁阀自动关断具有较强的适应性.

Aiming at the key technique of the criterion for tankful water of train,we design a self-adapt control system based on development and design of configurable software. The system works in two steps. In manual step the system＇ s valves is operated by human being while the system automatically records the water pressure at the same time. Through several practice, the system can come into the automatic control step. The system can gather data of water pressure in different complex conditions when the solenoid valves are shut. On the basis of academic data, we can use experience data to optimize criterion that the water tank is full, so as to make the system more adaptive.
