本论文的主要内容是设计一套专门用于高层建筑自动喷淋式消防恒压给水的控制系统.该系统改变了以往由高位水箱和工频泵供水的模式,摒弃了供水不稳定的缺点,是一种安全可靠、快速稳定、节能、维护和管理方便的供水控制系统.
本论文设计的控制系统能控制两台稳压泵和两台消防主泵.稳压泵由工频电源供电,给消防管网及气压罐供水,使气压罐内始终储有30秒的消防水量,消防主泵由变频器供电恒压供水.稳压泵主要起到补水增压的作用,在管道系统渗漏使消防管网水压下降时自动投入工作.消防泵主要在发生火灾时投入运行,以消防管网的压力变送器压力信号作为反馈信号,反馈信号与PID调节仪设定值比较后输出,调节消防供水压力使其保持在恒压状态.
本系统设计以PLC为控制核心,实现了全自动控制的功能.两台稳压泵一用一备轮流工作交替运行,有故障能自动切换.两台消防泵也是一用一备,均能工频和变频运行,发生故障时备用泵能自动投入运行.当一台消防泵变频运行后水压仍然低于设定水压,备用泵会自动投入工作联合供水.本系统还设置了手动和自动的功能,并与消防控制中心联网,维护和管理非常方便.

The main content of this paper is devoted to design a high-rise building automatic constant pressure water spray fire-control system.The system has changed from previous high-water tanks and pumps for water supply mode,get rid of the shortcomings of the water supply instability,is a safe and reliable,fast and stability,energy saving,convenient maintenance and management of water supply control systems.
This paper designed control system can control two regulators pump and two main fire pumps.Regulators from the pump-frequency power supply,fire control network to the pressure tank and water supply,the pressure tank 30 seconds after all certificates have the fire water,fire pumps from the main power inverter constant pressure water supply.Regulators booster pump water supplement a major role in the leaking pipeline system so that the Fire Services Network automatically when water pressure dropped to work.The main fire pump in case of fire and put into operation,the pipeline network to fire the pressure transmitter signal pressure as feedback signals,and PID feedback signal conditioning instrument settings comparison of output,regulating water pressure on fire to keep constant pressure in the state .
PLC to design the system for the control of the core to achieve a fully automated control functions.Two regulators of a pump with a rotating work by the turn of operation,a failure to automatically switch.Two fire pump is also a one-up,both the frequency and frequency operation,failure of backup pump automatically put into operation.When a fire pump frequency operation after the hydraulic pressure is still lower than the set,the backup pump will automatically enter the workforce joint water supply.The system also set up a manual and automatic features,and fire control center networking,maintenance and management is very convenient.
