毕业设计、毕业论文 题 目 火灾报警与消防连动系统的设计 电气与电子工程学院 指导教师 姓 名 摘 要 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正常整定值比较、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、延时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、切除非消防电源、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时报警后确定。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机、排烟阀等，并接收反馈信号。 Now, with electronic products used in human life more and more widely,the resulting fire, more and more, we live in fire hazards lurking around everywhere. To avoid fires and reduce fire losses,we must follow the “hidden dangers fire in prevention is better than disaster relief, the responsibility is extremely heavy”the concept design and improvement of automatic fire alarm system, fire nipped in the bud,the maximum reduce the loss of social wealth. The system can be installed in all fire uints, which is responsible for continuously monitoring the side to start the inspection singal, monitor the site of temperature, concentration, and continuous feedback to the alarm controller, the controller will receive the signal and the normal memory setting value was determined by comparing to determine the fire. When fire occurs, can achieve sound and light alarm, fault diagnosis, concentration display, alarm limit settings, delay alarm and serial communication with the host computer is a simple structure, stable performance, easy to use, inexpensive, intelligent smoke sensor, has some practical value. Fire pump, sprinkler pump starts, smoke and exhaust fan starts, the removal of non-fire power, the elevator landing, fire shutter down logic preparation, any confirmation of fire signal fire facilities are linked actions. In the system design, automatic recognition,
