地铁车站消火栓系统控制模式优化

阐述地铁车站消火栓系统的控制模式,并分析消火栓系统的操作模式,对手动启泵控制模式和自动启泵控制模式进行详细分析,从启动时间、运营管理、经济性等方面进行对比,得出手动控制模式在启动时间上具有优势,但存在人为误操作的可能;自动控制模式比手动操作模式增加了压力开关(流量开关)控制系统,投资会有所增加。优化两种控制模式,在设计手动启泵控制模式时增加自动巡检或其他线路故障报警功能,在设计自动启泵控制模式时,增设低流量或者低压力报警的流量开关或者压力开关,在消火栓系统出现小流量泄漏时,能及时报警,及时维修,避免消防泵在非消防状态下的错误启动。

Study on the model of optimizing control of fire hydrant system in subway station

The control mode of the fire hydrant system in the subway station is elaborated and the operation mode of the fire hydrant system is analyzed.The manual control mode and the automatic pump control mode are analyzed in detail.Judging from the perspective of starting time,operation management and economic performance,we come to the conclusion that manual control mode has an advantage in starting time,but there are the possibilities of human errors.The automatic control mode increases the pressure switch (flow switch) control system;therefore,the investment will be increased.Optimization of the two control modes is also discussed.In the design of manual pump control mode,the automatic inspection should be increased or alarm function for other lines should be added.In the design of automatic pump control mode,the addition of low flow or low pressure alarm flow switch or pressure switch in the fire hydrant system is necessary.When small leakage happens,the system is supposed to alarm and get repaired in time,avoiding the fire pump mistakenly started in the non-fire state.
