【正文】 本 科 畢 業(yè) 設(shè) 計(jì) 畢業(yè)設(shè)計(jì)題目：紅外線監(jiān)控遙控報(bào)警器設(shè)計(jì) 學(xué)生姓名： 學(xué) 號(hào)： 系 別：電子工程學(xué)院 專業(yè)班級(jí)： 指導(dǎo)教師姓名及職稱： 起止時(shí)間： 摘 要 隨著時(shí)代的不斷進(jìn)步，人們對(duì)自己所處環(huán)境的安全性提出了更高的要求，尤其是在家居安全方面，不得不時(shí)刻留意那些不速之客。 隨著電子技術(shù)的發(fā)展，人類不斷研究，不斷創(chuàng)新紀(jì)錄，人們自身的安防意識(shí)也在逐漸增強(qiáng)。紅外線具有隱蔽性，在露天防護(hù)的地方設(shè)計(jì)一束紅外線可以方便地檢測(cè)到是否有人出入。此類裝置設(shè)計(jì)的要 點(diǎn)：其一是能有效判斷是否有人員進(jìn)入；其二是盡可能大地增加防護(hù)范圍。 該報(bào)警器能探測(cè)人體發(fā)出的紅外線，當(dāng)人進(jìn)入報(bào)警器的監(jiān)視區(qū)域內(nèi)，即可發(fā)出報(bào)警聲，適用于家庭、辦公室、倉(cāng)庫(kù)、實(shí)驗(yàn)室等比較重要場(chǎng)合防盜報(bào)警。本設(shè)計(jì)是利用熱釋電紅外線傳感器探測(cè)人體輻射出的紅外線信號(hào)原理設(shè)計(jì)出來(lái)的人體紅外線感應(yīng)報(bào)警器。內(nèi)容廣泛，靈活應(yīng)用。 關(guān)鍵詞 傳感器 放大器 靈敏度 基準(zhǔn)電壓 Abstract Because the ages progresses unremittingly, people39。s make higher request the safety of place environment to them , particularly at the aspect of home safey, which have to keep in mind those guest who es uninvited every moment. Along with electronics technical development, the mankinds continuously study and continuously innovate to record, the consciousness of people39。s oneself defends also gradually strengthen. The infrared ray has concealment and design a bunch of infrared ray in the place of openair protection can expediently examine if someone es in and goes out. This kind of device designs of important point: One is effective ability judgment if someone39。s member gets into the room。 The other is the earth increment the protection scope is possibly. The alarm can detect infrared issued by the body, can sound an alarm into the alarm monitoring area, and applies to homes, offices, warehouses laboratories and other important occasions, antitheft alarm. This design is to make use of heat to release electricity infrared ray to spread a feeling machine to probe into the human body infrared ray that the infrared signal principle design that the human body radiates es out to respond to report to the police a machine. The contents of sensor is extensive, vivid applied.
