【正文】 ntration, etc.) response, and automatically generate a fire alarm signal devices. Fire response parameters according to different fire detectors into heat detectors, smoke detector, sensitive fire detectors, bustible gas detectors and fire detectors five basic types of posite. 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 fire alarm system is an indispensable ponent of the. (B) The fire alarm device in automatic fire alarm system to receive, display and transmit fire alarm signals, and can send control signals and control functions with other auxiliary equipment as the fire alarm device instructions. Fire alarm control is one of the most basic kind. Charged with the fire alarm control fire detectors provide a stable working power。 detector and the working status of the system itself。 the reception, conversion, processing a warning of fire detectors Shuchu。 Jinxing sound and light alarm。 Zhishi specific location and alarm time。 the same time supporting the implementation of appropriate control and many other tasks. Fire alarm system is a core ponent. In the fire alarm devices, some devices such as break, regional monitors, fire shows and other functions can not plete disc alarm device, which can be regarded as the evolution of fire alarm controller or supplement. Under certain conditions applied, and the fire alarm device fire alarm control belong.The basic function of fire alarm control are: the main power, backup power automatically converted, standby power charge function, power failure monitoring function, power functions working status indicator, power supply for the detector circuit function, control sensors or system failures, sound and light alarm, fire sound, light alarm, fire alarm and memory function, clock function unit, with priority being given fault function fire alarm, sound alarm sound audible alarm mute and again. (C) Fire alarms in automatic fire alarm system to send different from the environment, sound, light the fire alarm signal device called the fire alarms. It sound, light and sound approach to the issue of fire alarm signals alarm area to warn people to adopt safe evacuation, fire fighting and rescue measures. (D)Fire control equipment in automatic fire alarm system, when receiving the fire alarm, automatically or manually start the related firefighting equipment and display devices of their state, known as the fire control equipment. Include fire alarm control, automatic fire extinguishing system control device, fire hydrant system control devices, smoke exhaust system and air conditioning and ventilation system control device, normally open fire doors, fire shutter control device, the lift back down control equipment, and fire emergency radio, fire alarms, fire munications equipment, fire evacuation signs and emergency lighting control devices, control devices in some or all. Fire control equipment normally installed in the fire control center to facilitate the implementation of centralized control. While others set fire control equipment, fire fighting equipment is located in the charged field, but its actions must be returned fire control signal, bined with the implementation of centralization and decentralization of control. (E) fire alarm system power supply electrical equipment belonging to the fire, the main power should be in the fire power, standby power use of battery. 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.Automatic fire alarm system is generally divided into the decentralized, centralized and distributed. A distributed system consists of non intelligent controller of intelligent detection nodes, by detecting nodes plete fire state judgment。 centralized system is posed of intelligent controller and a plurality of non intelligent nodes, detection node will only fire parameter is transmitted to the controller, the controller of intelligent judgment of fire state。 controller and the detection nodes of a distributed system are intelligent, but also the future development direction of the automatic fire alarm system. The western developed countries of the fire alarm system is perfect, set up fire control special service agencies, to provide fire alarm data munication service for city fire, provide reliable fire for fire alarm information。 secondly, the use of puter technology, network technology, munication technology, remote transmission equipment for fire monitoring system of realtime monitoring and fault the general construction, public alarm monitoring system network, the automatic fire alarm system, access network, so that the fire control center to quickly determine the exact location of fire, fire brigade quickly arrived at the scene and scheduling. Once again, especially in the developed countries such as Japan and Europe, automatic fire alarm system have entered the family, and access the city fire protection network, make the city fire larger network, covering a wider range of. In recent years, the use of wireless munication mode of the automatic fire alarm system is quietly on the rise in foreign countries.中文翻譯火災自動報警系統(tǒng)傳統(tǒng)電子安全報警系統(tǒng)主要是通過傳感器自動檢測，產(chǎn)生報警信號，從現(xiàn)場發(fā)出報警信號或通過專門電纜近距離報警，從而引起人們的警覺。通過多年的研究和發(fā)展，現(xiàn)在的報警器可以說是門類眾多。由于報警器的飛速發(fā)展和社會各個領(lǐng)域的急切需要，能應用的領(lǐng)域越來越多，特別是在民用領(lǐng)域更是急速發(fā)展。 近年來，紅外線報警器已經(jīng)成為報警領(lǐng)域的一個熱點，由于其采用的是不可見的紅外線探測，所以具有隱蔽性好、安全等特點。紅外線傳感器按機理不同可以分為光探測型和熱探測型。光探測傳感器是利用光子效應的紅外探測器。這類傳感器響應速度快、靈敏度高、檢測特性好，但需要冷卻，使用不方便。而且器件的檢測靈敏度與紅外波長有關(guān)。熱探測傳感器是利用熱釋電效應的紅外探測器。在接收到目標的紅外輻射后溫度升高，溫度的升高又引起傳感器內(nèi)部某些物理量的變化，通過檢測物理量的變化來確定紅外線輻射。這類傳感器在室溫條件下工作，檢測靈敏度也很高，響應速度也很快，而且與紅外線輻射波長無關(guān)，可探測功率只受背景輻射的限制，應用很方便。本文設計的是被動式熱釋電紅外探測器。文中主要論述了熱釋電的原理、熱釋電探測器的特性、BISS0001傳感信號處理器、555定時器組成的多諧振蕩報警電路等內(nèi)容。最后設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
