1、毕业设计论文题目火灾报警与消防连动系统的设计学院专业班级指导教师姓名目前,随着电子产品在人类生活中的使用越来越广泛,由此引起的火灾也越来越多,在我们生活中到处潜伏着火灾隐患。为了避免火灾以及减少火灾造成的损失,我们必须按照“隐患险于明火,防患胜于救灾,责任重于泰山”的概念设计和完善火灾自动报警系统,将火灾消灭在萌芽状态,最大限度地减少社会财富的损失。本系统可安装在各防火单位,它负责不断地向所监视的现场发射巡检信号,监视现场的温度、浓度等,并不断反馈给报警控制器,控制器将接到的信号与内存的止常整定值比较
2、、判断确定火灾。当发生火灾时,可实现声光报警、故障自诊断、浓度显示、报警限设置、延吋报警及与上位机串口通信等,是一种结构简单、性能稳定、使用方便、价格低廉、智能化的烟雾传感器,具有一定的实用价值。消防泵、喷洒泵启动,防烟和排烟风机启动、切除非消防屯源、电梯迫降、防火卷帘的下降逻辑编制,任何确认火灾信号均联动消防设施动作。在系统设计上,自动确认,用两组探测器或两种不同类别的火灾探测器同吋报警后确定。确认火灾后,切除非消防电源和电梯迫降;火灾报警后应停止空调送风,关闭电动防火阀,启动有关部位的防烟和排烟风
