【正文】 時器組成的多諧振蕩報警電路等內(nèi)容。最后設(shè)計完成了熱釋電紅外探測報警器的硬件電路。隨著現(xiàn)代家庭用火、用電量的增加，家庭火災發(fā)生的頻率越來越高。家庭火災一旦發(fā)生，很容易出現(xiàn)撲救不及時、滅火器材缺乏及在場人驚慌失措、逃生遲緩等不利因素，最終導致重大生命財產(chǎn)損失。探討家庭火災的特點及防火對策， 對于預防家庭火災，減少火災損失具有現(xiàn)實意義 在現(xiàn)代城市家庭里，許多人因不懂家庭安全常識引起火災事故，使好端端的幸福家庭轉(zhuǎn)眼間毀于一旦,有的導致家破人亡,而且一旦發(fā)生居民家庭火災，處置不當、報警遲緩,是造成人員受害的原因。人們應該積極了解家庭火災的主要起因，掌握防止發(fā)生火災的知識和萬一發(fā)生火災時保護自己的方法,及時消除隱患。 英國每年發(fā)生50000起以上的嚴重家庭火災，其中大部分火災造成人員傷亡和重大的家庭財產(chǎn)損失，有的還連累左鄰右舍，火災損失更加慘重。在調(diào)查火災起因的時候，絕大多數(shù)發(fā)生火災家庭的當事人說，以前總覺得火災是人家的事情，與自己離得很遠，沒有想到這一次竟然會發(fā)生在自己的頭上。 家庭火災的主要原因是麻痹大意，沒有及時采取預防措施。在我國的一些大中城市，幾乎每天都發(fā)生家庭火災，所以防火是每個家庭必須時刻注意的問題。假如能根據(jù)您家的實際情況預先采取簡單的防火措施，一些悲劇是完全可以避免的。火災自動報警系統(tǒng)是為了通知早期發(fā)現(xiàn)火,并采取有效措施,控制和戰(zhàn)斗的火災,并設(shè)置在建筑物或其他地方的火災自動設(shè)備,是那些有一個強大的工具來滅火。火災報警系統(tǒng),火災探測器一般、區(qū)域集中報警報警和組成。也需要根據(jù)該項目與各種消防設(shè)施和通訊設(shè)備連接,形成了一個中央控制系統(tǒng)。從自動報警、自動消防、疏散過程顯示,指導,系統(tǒng),消防了一個完整的檔案管理、消防系統(tǒng)。火災探測器是火災探測手段,如舞臺的煙和火將會產(chǎn)生高溫火焰的細胞。光和熱的煙霧,為電子信號通過發(fā)現(xiàn)者警報或自動滅火系統(tǒng)開始消防。地方的地板報警探測器可以發(fā)送信號轉(zhuǎn)變的聲、光報警,火在屏幕上顯示房間號碼。同時監(jiān)測濃度一定的樓層的報警(如監(jiān)視器位于建筑物的消防控制中心)輸出信號或控制自動滅火系統(tǒng)。收到報警信號的濃度的聲、光的方式顯示,屏幕上也能體現(xiàn)具體著火層和房間號碼,飛機停止服用第一個鬧鐘來記錄時間、使用電話,但是也快成的火災報警指點。此外,你可以控制的滅火系統(tǒng)或信號發(fā)送到消防的房間。火災自動報警系統(tǒng)是由觸發(fā)裝置、火災報警、火災報警裝置及其它輔助功能的裝置組成的一個按鈕消防報警系統(tǒng)的火災報警系統(tǒng)。它可以燃燒的煙火災的早期階段,光和熱放療和其他的物理量,溫度有關(guān)。攝影和其他煙和火事探測器成電子信號,傳送給火災報警控制器,同時也顯示了這個地點的火里,火的記錄時間。一般火災報警系統(tǒng)、自動噴淋系統(tǒng)、消火栓系統(tǒng)、防排煙系統(tǒng)、通風系統(tǒng)、空調(diào)系統(tǒng)、防火門、火百葉窗,煙幕之間的相互影響,以及其他相關(guān)設(shè)備的自動或手動發(fā)出指令開始對應的設(shè)備。(A)觸發(fā)裝置在火災自動報警系統(tǒng)、自動或手動火災報警信號裝置產(chǎn)生稱為觸發(fā)條件,包括火災探測器和手動火災報警按鈕。火災探測器是它能發(fā)射參數(shù)(煙、溫度、火焰輻射、氣體濃度等)的反應,并自動生成一個火災報警信號裝置。火響應參數(shù),根據(jù)不同的火災探測器變成熱能探測器、煙霧探測器,敏感的火災探測器,可燃氣體探測器和火災探測器的五個基本類型復合材料。不同類型的火災探測器為不同類型的火災和不同的地方。手動火災報警按鈕火災報警信號生成的手動啟動火災自動報警系統(tǒng)裝置、火災自動報警系統(tǒng)是一個不可或缺的組成部分。(B)火災報警裝置在火災自動報警系統(tǒng)接收、顯示、傳輸火災報警信號,可以發(fā)送控制信號、控制功能和其他輔助設(shè)備的火災報警裝置的指令。火災報警控制是一種最基本的類。被指控的火災報警控制火災探測器提供一個穩(wěn)定的工作能力。探測器和工作狀態(tài)下的系統(tǒng)本身。接待、轉(zhuǎn)換、處理一個警告,火災探測器Shuchu。金興聲光報警功能。Zhishi具體地點和鬧鐘時間。同時支持采用恰當?shù)目刂坪驮S多其他任務?；馂膱缶到y(tǒng)的核心組成部分。在火災報警設(shè)備,一些設(shè)備,如打破、區(qū)域監(jiān)測、火顯示等功能不能夠完成閥瓣報警裝置,可視為演化的火災報警控制器或補充。在一定條件下應用,火災報警裝置火災報警控制的歸屬。基本功能:火災自動報警控制的主要力量,備用電源自動轉(zhuǎn)換開關(guān),備用電源充電功能、動力功能、動力功能故障監(jiān)測工作狀態(tài)指示器,電源檢測器電路功能、控制傳感器或系統(tǒng)故障、聲音、光報警、火災聲、光報警、消防報警及記憶功能,時鐘功能單元,優(yōu)先被給予的錯功能火災報警聲警報聲警報聲啞巴又一遍。(C)火災警報器在火災自動報警系統(tǒng)發(fā)送,從不同的環(huán)境、聲音、光火警信號設(shè)備叫火災警報器。這聲音、光和聲音的方法對這一問題的火災報警信號報警區(qū)來警告人們采取安全疏散、火災撲救措施。(D)在消防設(shè)備火災自動報警系統(tǒng),當受到火災報警、自動或手動啟動相關(guān)消防設(shè)備顯示裝置的狀態(tài),如大家所知的消防設(shè)備。包括火災報警控制、自動滅火系統(tǒng)控制裝置、消火栓系統(tǒng)控制裝置、排煙系統(tǒng)、空調(diào)和通風系統(tǒng)的控制裝置,通常開防火門、火快門控制裝置、電梯下來控制設(shè)備、消防應急無線電、火災報警、消防通信設(shè)備,消防疏散標志和應急照明控制設(shè)備、控制設(shè)備在某些或全部。消防設(shè)備通常安裝在消防控制中心,便于實施集中控制。而另一些人放火控制設(shè)備、消防設(shè)備位于這些帶電的領(lǐng)域,但它的行動都必須予以回擊控制信號,結(jié)合實施集權(quán)與分權(quán)進行控制。(E)火災報警系統(tǒng)的電源電氣設(shè)備屬于火,形成的主要動力應該在火力,備用電源使用的電池。除了消防報警系統(tǒng)的電源控制器、供電,也關(guān)系到系統(tǒng)為消防設(shè)備,如電源。原文：Fire alarmThe 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 special electriccable near distance, thus causes people39。s 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 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 security. 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 good, but needs tocool, uses not conveniently. Moreover the ponent 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, 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,moreover 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 elaborated 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 posed. Finallydesigned pletes has hotly released the electricity infrareddetection alarm apparatus the 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 firefighting equipment and the presence of panicstricken people, 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 modern urban family, because of lot of people do not understand mon 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 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 assets, and some result in the neighbors, more heavy fire losses. Investigate the causes of fire in time, the vast majority of home fires happen partie
