智能消防供水系统设计

摘要

随着我国智能建筑（IB）业的发展，高层建筑及建筑群体越来越多，从而也促进消防系统以迅猛的速度向前迈进。在智能建筑的建筑物自动化系统（BAS）中消防系统是非常重要的一个子系统, 担负着保障人员及财产安全的重任。该论文设计了智能建筑的消防系统，主要是消防系统的感应机构和其执行机构。着重论述了利用变频器、压力传感器、可编程序控制器组成的消防智能供水控制系统。此系统具有自动定期检查消防泵能否正常工作，并且当火灾发生时可自动启动消防泵，克服了以前人工操作或只能依赖于火灾传感器的情况。

本设计中采用了MCGS组态软件和西门子S7-200小型PLC控制器来组建本次消防供水系统。系统主要由集中管理个人计算机即上位机和可编程序控制器PLC构成。组态软件MCGS用于上位机监视，主要作用是监视消防过程；S7-200小型PLC则用于下位机的控制，主要作用是对采集信号的处理和对系统的PID控制。

The design of water supply for fire fightting

Abstract

With the development of Intelligence Building(IB) industry in our country, high buildings and building community are more and more, and that promote the fire fighting system to move forward with swift and violent speed. In Building Automation System(BAS) of Intelligence Building,the fire fighting system is a very important subsystem, and its assignment is to protect the safety of people and property. This thesis designed a fire system of a comprehensive building, about the part of response,including heat fire detectorand the part of execution. This thesis discusses improved water supply control system with constant pressure in the firefighting that is composed of transducer, pressure sensor, PLC as well as homemade controller. This system possesses the function that can automatically time-examine whether the fire engine works normally.Furthermore, thesystem possesses the function that can automatically start-upfire engine when fire happens and overcomethe status operated manually or depended on fire sensor formerly.

In this design, MCGS configuration software and the S7-200 small PLC controller are used to set up the fire fightting system. MCGS configuration software is used in the up-position machine process surveillance, the main function is to monitor the process. S7-200 small PLC uses in the lower-position control, the main function is to gather the signals and to launch the PID control.

Key words: fire fighting；fire alarm；water supply for fire fightting
