1、毕业设计（论文） 外文翻译 学生姓名： 侯典冉 学 号： 200880874211 专 业： 自动化 班 级： 自动 082 设计（论文）题目： 家庭智能报警系统的设计 指导教师： 魏平俊 2012 年 3 月 10 日 外文原文 The traditional electron safe alarm system mainly is through thesensor automatic detection, produces the alarm, sends out the alarmfrom the scene or reports to the police through the s

2、pecial electriccable near distance, thus causes peoples vigilance. Through manyyears research and the development, the present alarm apparatus maysay is the class is multitudinous. As a result of the alarm apparatusrapid development and the social each domain anxious need, can theapplication domain

3、be more and more many, specially is rapidlydevelops in the civil domain. In recent years, the infrared alarmapparatus already became reports to the police a domain hot spot,because it used was not the obviously infrared acquisition, thereforehad the hiding to be good, characteristic and so on securi

4、ty. Theinfrared sensor is different according to the mechanism may divideinto the light survey and the hot survey. The light acquisition sensor is uses the photon effect the infraredacquisition aid. This kind of sensor speed of response quick, thesensitivity high, the examination characteristic is g

5、ood, but needs tocool, uses not conveniently. Moreover the component examinationsensitivity and the infrared wave length concern. The hot acquisitionsensor is uses hotly releases the electricity effect the infraredacquisition aid. After receives the goal the infrared radiationtemperature increment,

6、the temperature elevates causes the sensorinterior certain physical quantities changes, through examinationphysical quantity change definite infrared emission. This kind ofsensor works under the room temperature condition, examinationsensitivity also very high, speed of response also very quick,more

7、over has nothing to do with with the infrared emission wavelength, may survey the power only to receive the background radiationthe limit, the application is very convenient. This article designs isthe passive form hotly releases the electricity infrared acquisitionaid. In the article mainly elabora

8、ted has hotly released theelectricity the principle, hotly releases content and so on manyalarm circuit which the electric detector the characteristic,the BISS0001 signal processor, 555 timers composed. Finallydesigned completes has hotly released the electricity infrareddetection alarm apparatus th

9、e hardware electric 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

10、, to escape unfavorable 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 m

11、odern urban family, because of lot of people do not understand common sense home security caused by fire, so that the happy family Goog leruined 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

12、 more about the 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 asse

13、ts, and some result 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 f

14、ires are the main 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 preven

15、tion measures, a 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 too

16、l to fight the fire. 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 fightin

17、g, evacuation guidance, 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

18、alarm or automatic 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 i

19、s located in the 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

20、record the timing, 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

21、devices and other 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

22、 signals, transmitted to the fire alarm controller, and also shows the site of the fire, the fire record of the time. General fire alarm system and automatic sprinkler system, fire hydrant systems, smoke control systems, ventilation systems, air conditioning system, fire doors, fire shutter, smoke screen and other related equipment interaction, automatically or manually issue
