地铁环控系统风机风阀联动控制方式研究

Studies of The Linkage Controlling Way about Fan and Air Valve Used in Metro Environmental Control System

针对地铁环控系统风机风阀联动时的现行控制方式,基于工程实践中出现的运营调试问题,分析了缺陷产生的原因及其危害性。通过研究风机风阀联动的基本需求,摒弃了原来导致联动控制缺陷的并列控制方式,创新性地提出了风机风阀的主从控制方式,简化了控制系统,工程实施简单,运营简便。

In view of the metro environment control system fan air valve linkage when the current control mode and based on the engineering practice in operation debugging problems, the paper analyses the reasons causing the defects and the harmfulness, then the paler research linkage basic needs about the fan and air valve, discard the original cause linkage control defects in parallel control mode, put forward the innovative fan air valve of the master-slave control mode. the control system is simplified, the engineering implementation is simple, operation is simple.
