1、指导教师:孟洁 所在学院:信息技术学院 专业:电气工程及其自动化 中国大庆 2012年5 月 Automatic fire alarm system The traditional electron safe alarm system mainly is through the sensor automatic detection, produces the alarm, sends out the alarm from the scene or reports to the police through the special electric cable near distance, th

2、us causes peoples vigilance. Through many years research and the development, the present alarm apparatus may say is the class is multitudinous. As a result of the alarm apparatus rapid development and the social each domain anxious need, can the application domain be more and more many, specially i

3、s rapidly develops in the civil domain. In recent years, the infrared alarm apparatus already became reports to the police a domain hot spot, because it used was not the obviously infrared acquisition, there for had the hiding to be good, characteristic and so on security. Theinfrared sensor is diff

4、erent according to the mechanism may divide into the light survey and the hot survey. The light acquisition sensor is uses the photon effect the infrared acquisition aid. This kind of sensor speed of response quick, the sensitivity high, the examination characteristic is good, but needs to cool, use

5、s not conveniently. Moreover the component examination sensitivity and the infrared wave length concern. The hot acquisition sensor is uses hotly releases the electricity effect the infrared acquisition aid. After receives the goal the infrared radiation temperature increment, the temperature elevat

6、es causes the sensor interior certain physical quantities changes, through examination physical quantity change definite infrared emission. This kind of sensor works under the room temperature condition, examination sensitivity also very high, speed of response also very quick, moreover has nothing

7、to do with the infrared emission wavelength, may survey the power only to receive the background radiation the limit, the application is very convenient. This article designs is the passive form hotly releases the electricity infrared acquisition aid. In the article mainly elaborated has hotly relea

8、sed the electricity the principle, hotly releases content and so on many alarm circuit which the electric detector the characteristic, the BISS0001 signal processor, 555 timers composed. Finally designed completes has hotly released the electricity infrared detection alarm apparatus the hardware ele

9、ctric circuit. With the modern family use of fire, electricity consumption increases, the frequency of home fires is getting higher and higher. The family of fire, it is easy to fight does not occur promptly, the lack of fire-fighting equipment and the presence of panic-stricken people, to escape un

10、favorable factors, such as retardation, which eventually led to a significant loss of life and property. Explore the characteristics of the family of fire and fire prevention measures. For the prevention of domestic fires, reducing the fire losses have practical significance . In the modern urban fa

11、mily, because of lot of people do not understand common sense home security caused by fire, so that the happy family Goog ruined blink of an eye, and some lead to destruction, but the event of household fires, improper disposal, alarm delay is caused so that people should get to know more about the

12、main causes of household fires, master to prevent the fire of knowledge and in case of fire to protect his or her own way, timely elimination of The United Kingdom each year more than 50000 families of serious fires, most of them fire casualties and significant loss of household assets, and some res

13、ult in the neighbors, more heavy fire losses. Investigate the causes of fire in time, the vast majority of home fires happen parties said that the fire always feel that things are other people with their own far away, did not think this will happen even in the top of his head. Home fires are the mai

14、n reason for negligent not to take timely preventive measures .In some of our large and medium-sized cities, almost every day family fires, fire prevention is so each family must always pay attention to. If your home based on the actual situation in advance to take simple fire prevention measures, a

15、 number of tragedies are entirely avoidable. Automatic fire alarm system is in order to inform the early detection of fire, and take effective measures to control and fight fires, and set in a building or other place of an automatic fire facilities, is that people with a powerful tool to fight the f

16、ire. Fire alarm system, fire detectors generally, regional centralized alarm alarm and composition; also be required under the project with various fire-fighting facilities and communication devices linked to form a central control system. From automatic alarm, automatic fire fighting, evacuation gu

17、idance, system process shows that, fire up a complete file management, fire control system. Fire detectors are fire detection devices, as in the stage of fire will produce smoke with high temperature flame cells. The smoke, heat and light into electrical signals through the detector alarm or automat

18、ic fire extinguishing system to start fighting the fire in time. Area where the floor of alarm detector can send the signal into sound and light alarm, and fire on the screen showing the room number; while also monitoring the concentration of certain floors of alarm （if the monitor is located in the

19、 building fire Control Center） output signal or control automatic fire extinguishing system. Concentration of alarm signal is received by way of sound and light show, and the screen also shows the specific fire floor and room number, the plane stopped taking the first alarm clock to record the timin

20、g, use of the machine-specific phones, but also quickly to the fire alarm to give directions and. In addition, you can control the fire extinguishing system or signal transmission to the fire control room. Automatic fire alarm system is by the trigger devices, fire alarm, fire alarm devices and othe

21、r auxiliary functions of the device with the composition of a button fire alarm system fire alarm system. It can fire early stages of burning smoke, heat and light radiation and other physical quantities, by temperature. Photographic and other smoke and fire detectors into electrical signals, transm

Fire response parameters according to different fire detectors into heat detectors, smoke detector, sensitiv

25、e fire detectors, combustible gas detectors and fire detectors five basic types of composite. Different types of fire detectors for different types of fires and different places. Manual fire alarm button fire alarm signal generated manually start the automatic fire alarm system devices, automatic fi
