摘要：現(xiàn)階段，隨著電子類產(chǎn)品在人們生活中的使用越來越頻繁，由此引發(fā)造成的火災(zāi)也呈現(xiàn)上升趨勢，在我們生活的周圍到處都存在著火災(zāi)隱患。為了避免和減少火災(zāi)造成的人員和財產(chǎn)的損失，我們必須嚴(yán)格按照“隱患險于明火，防患勝于救災(zāi)，責(zé)任重于泰山”的理念設(shè)計并且完善火災(zāi)自動報警裝置，及時發(fā)現(xiàn)并將火災(zāi)發(fā)現(xiàn)和控制在初發(fā)生階段，盡可能地減少人民群眾傷亡和財產(chǎn)的損失。 設(shè)計一種應(yīng)用在各種場所的防火報警裝置。將AT89S52 單片機(jī)作為主控制器, 火焰檢測傳感器檢測熱源,煙霧檢測傳感器MQ-2檢測煙霧，并把信號傳給單片機(jī)，做出火情判斷，并實(shí)現(xiàn)火災(zāi)聲光報警;利用 HC-SR501人體感應(yīng)模塊，對所發(fā)生火災(zāi)的空間進(jìn)行檢測，判斷是否有人，便于救助；用PL2302實(shí)現(xiàn)電腦和單片機(jī)實(shí)現(xiàn)串口通信能進(jìn)行遠(yuǎn)程監(jiān)控。是一種結(jié)構(gòu)簡單、性能穩(wěn)定、使用方便、價格低廉、智能化的報警器，具有一定實(shí)用價值。 關(guān)鍵詞：AT89S52；火焰檢測傳感器；HC-SR501；煙霧傳感器；上位機(jī)
ABSTRACT：At the present stage, with the frequent use of electronic products in people's daily life, the resulting fire accidents appear a rising trend; hidden dangers of fire exist around us.In order to prevent and cut the losses of human life and property, we must design and perfect the fire autoalarm on the base of such concept “Hidden danger is far more perilous than visible fire. Prevention is better than cure. Duty is more important than anything else”, detecting and bringing the fire situation under control when it is at the start stage, so as to minimize damage. To design a fire autoalarm which can be used in various places, taking AT89S52 SCM as main controller, the flame detection sensor detect heat producer and smoke detection sensor MQ-2 do smoke detection, then transmit signals to SCM which will make judgment on the fire situation and to achieve the fire acoustoopic alarm task; Taking advantage of HC-SR501 Human Body Induction Module to detect the fire space obtaining judgment on whether there is person to rescue, use PL2302 to achieve serial communication between computer and SCM for remote monitoring. This simple structured intelligent alarm with stable function which have certain practical value is convenient to use and cheap.
