1、本科毕业生外文文献翻译指导教师:孟洁所在学院:信息技术学院专业:电气工程及其自动化黑施扛八中国大庆2012年5月Automatic fire alarm systemThe 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 dist

2、ance, thus causes people's 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

3、, specially is 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 se

4、nsor is different 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

5、to cool, uses 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 temper

6、ature elevates 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

7、has nothing 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

8、 hotly released the electricity the principle, hotly releases content and so on many alarm circuit which the electric detector the characteristic, the BISSOOO1 signal processor, 555 timers composed. Finally designed completes has hotly released the electricity infrared detection alarm apparatus the

9、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, t

10、o 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 modern

11、 urban family, 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 thatpeople should get to know more ab

12、out 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 assets, and

13、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 fires are

14、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 prevention mea

15、sures, 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 tool to figh

16、t the fire. Fire alarm system, fire detectors generally, regional centralized alarm alarm and composition; also be required under the project with various firefighting facilities and conimunication devices linked to form a central control system. From automatic alarm, automatic fire fighting, evacua

17、tion 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 alarm or a

18、utomatic 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

19、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 record the

20、 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 devices and

21、 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 signals, t

22、ransmitted 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 o

In addition to fire alarm system power controller, power supply, but also related to the system for the fire control equipment such as power supply.火灾自动报警系统传统电子安全报警系统主要是通过传感器自动检测,产生报警信号,从现场发

36、 出报警信号或通过专门电缆近距离报警,从而引起人们的警觉。通过多年的研究和 发展,现在的报警器可以说是门类众多。由于报警器的飞速发展和社会各个领域的 急切需要,能应用的领域越来越多,特别是在民用领域更是急速发展。近年来,红外线报警器已经成为报警领域的一个热点,由于其采用的是不可见 的红外线探测,所以具有隐蔽性好、安全等特点。红外线传感器按机理不同可以分 为光探测型和热探测型。光探测传感器是利用光子效应的红外探测器。这类传感器 响应速度快、灵敏度高、检测特性好,但需要冷却,使用不方便。而且器件的检测灵 敏度与红外波长有关。热探测传感器是利用热释电效应的红外探测器。在接收到目 标的红外辐射后温度升

37、高,温度的升高乂引起传感器内部某些物理量的变化,通过检 测物理量的变化来确定红外线辐射。这类传感器在室温条件下工作,检测灵敏度也 很高,响应速度也很快,而且与红外线辐射波长无关,可探测功率只受背景辐射的限 制,应用很方便。本文设计的是被动式热释电红外探测器。文中主要论述了热释电 的原理、热释电探测器的特性、BISS0001传感信号处理器、555定时器组成的多谐 振荡报警电路等内容。最后设计完成了热释电红外探测报警器的硬件电路。随着现代家庭用火、用电量的增加,家庭火灾发生的频率越来越高。家庭火灾 一旦发生,很容易出现扑救不及时、灭火器材缺乏及在场人惊慌失措、逃生迟缓等 不利因素,最终导致重大生命

38、财产损失。探讨家庭火灾的特点及防火对策,对于预防 家庭火灾,减少火灾损失具有现实意义。在现代城市家庭里,许多人因不懂家庭安全 常识引起火灾事故,使好端端的幸福家庭转眼间毁于一旦,有的导致家破人亡,而且 一旦发生居民家庭火灾,处置不当、报警迟缓,是造成人员受害的原因。人们应该积 极了解家庭火灾的主要起因,掌握防止发生火灾的知识和万一发生火灾时保护自己 的方法,及时消除隐患。英国每年发生50000起以上的严重家庭火灾,其中大部分火 灾造成人员伤亡和重大的家庭财产损失,有的还连累左邻右舍,火灾损失更加惨重。 在调查火灾起因的时候,绝大多数发生火灾家庭的当事人说,以前总觉得火灾是人家 的事情,与自己离

39、得很远,没有想到这一次竟然会发生在自己的头上。家庭火灾的主要原因是麻痹大意,没有及时采取预防措施。在我国的一些大中 城市,几乎每天都发生家庭火灾,所以防火是每个家庭必须时刻注意的问题。假如能 根据您家的实际情况预先采取简单的防火措施,一些悲剧是完全可以避免的。火灾自动报警系统是人们为了早期发现通报火灾,并及时采取有效措施,控制 和扑灭火灾,而设置在建筑物中或其它场所的一种自动消防设施,是人们同火灾作斗争的有力工具。火灾报警系统,一般由火灾探测器、区域报警器和集中 报警器组成;也可以根据工程的要求同各种灭火设施和通讯装置联动,以形成中心控 制系统。即由自动报警、自动灭火、安全疏散诱导、系统过程显示、消防档案管理 等组成一个完整的消防控制系统。火灾探测器是探测火灾的仪器,由于在火灾发生 的阶段,将伴随产生烟雾、高温格火光。这些烟、热和光可以通过探测器转变为电 信号报警或使自动灭火系统启动,及时扑灭火灾。区域报警器能将所在楼层之探测 器发出的信号转换为声光报警,并在屏幕上显示出火灾的房间号;同时还能监视若干 楼层的集中报警器(如果监视整个大楼的则设于消防控制中心)输出信号或控制自动 灭火系统。集中报警是将接收到的信号以声光方式显示出来,其屏幕上也具体显示 出着火的楼层和房间号,机上停走的时钟记录下首次报警时间性,利用本机专用电话, 还可迅速发出指示和向消防队报警。此外,
