【正文】 出人體輻射的紅外線能量變化,并將其轉(zhuǎn)換成電壓信號輸出。這種熱釋電紅外傳感器能以非接觸形式檢測 出人體輻射的紅外線,并將其轉(zhuǎn)變?yōu)殡妷盒盘枺盟谱鞯姆辣I報警器與目前市場上銷售的許多防盜報警器材相比,具有如下特點: ●不需要用紅外線或電磁波等發(fā)射源。由于紅外線是不見光,有很強的隱蔽性和保密性,因此在防盜、警戒等安保裝置中得到了廣泛的應用,此外,在電子防盜、人體探測等領域中,被動式熱釋電紅外探測器也以其價格低廉、技術性能穩(wěn)定等特點而受到廣大用戶和專業(yè)人士的歡迎。因此,越來越多的居民家庭對財產(chǎn)安全問題十分擔憂。 緒論 近年來,隨著改革開放的深入發(fā)展,電子電器的飛速發(fā)展 .人民的生活水平有了很大提高。 斷電保護電路 ............................................................................... 錯誤 !未定義書簽。 最小硬件系統(tǒng)部分電路 ................................................................................ 11 AT89C51時鐘振蕩電路 ............................................. 錯誤 !未定義書簽。 關鍵詞:紅外線熱釋電傳感器 熱敏電阻 LM324 放大器; 聲光報警; Abstract: The design for the name infrared wireless infrared detectors. This is a new type of multifunctional wireless security detectors with warning functions. The physical design will be functional expansion is good, and advanced hardware configuration advantages. This sets warning systems to prevent theft and the pursuit of thieves, have important practical significance. The pletion of the design driven mainly by two factors, first, to meet consumer demand and the extent to which lead;Second, the development of science and technology. The design of the following main characteristics : 1. As antitheft warning system uses unique, which requires antitheft warning system to cope with the continuous improvement of its function of the thieves are stealing tools. In the design, fully consider this matter, it has very good functional system expansionary, on different occasions, the system improved. 2. In the design, taking into account the actual environment and the safety of users against the request. 3. A certain antijamming capabilities, can prevent misreporting . High sensitivity and reliability of the system.
