隨著半導(dǎo)體電子元件的不斷發(fā)展,現(xiàn)階段人們家庭智能防盜報(bào)警器不管在工藝和產(chǎn)品質(zhì)量方面都有很大的提高,同時(shí)在價(jià)格方面也出現(xiàn)了大幅的下降,現(xiàn)在價(jià)格大概到千元左右,這給平常家庭使用家庭防盜報(bào)警器的使用帶來了很大的便利.但是常見的家庭防盜報(bào)警器都有哪些分類呢?濟(jì)南瑞安電子有限公司給出了詳細(xì)的介紹:

With the continuous development of semiconductor electronic components, family intelligent anti-theft alarm at this stage no matter in terms of technology and product quality are greatly improved, but also a sharp decline in prices, now the price to about one thousand yuan, the use of household anti-theft alarm brings great convenience to the ordinary family. But the family anti-theft alarm, what are the common classification? Ji'nan Ruian Electronics Co. Ltd is given in detail:

1、主動(dòng)紅外探測(cè)器:由紅外發(fā)射器和紅外接收器組成.紅外發(fā)射器發(fā)射一束或多數(shù)經(jīng)過調(diào)制過的紅外光線投向紅外接收器.發(fā)射器與接收器之間沒有遮擋物時(shí),探測(cè)器不會(huì)報(bào)警.有物體遮擋時(shí),接收器輸出信號(hào)發(fā)生變化,探測(cè)器報(bào)警.

1, active infrared detector is composed of an infrared emitter and an infrared receiver into the infrared receiver. A beam or most modulated infrared light emitted by the infrared emitter. No obstructions between the transmitter and the receiver, the detector will not alarm. Covered when the receiver output signal changes, the detector alarm.

2、被動(dòng)紅外探測(cè)器:中有2個(gè)關(guān)鍵性元件,一個(gè)是菲涅爾透鏡,另一個(gè)是熱釋電傳感器.自然界中任何高于溫度(-273o)的物體都會(huì)產(chǎn)生紅外輻射,不同溫度的物體釋放的紅外能量波長也不同.人體有恒定的體溫,與周圍環(huán)境溫度存在差別.當(dāng)人體移動(dòng)時(shí),這種差別的變化通過菲涅爾透鏡被熱釋電傳感器檢測(cè)到,從而輸出報(bào)警信號(hào).

2, passive infrared detectors: there are 2 key elements, a Finel lens, a pyroelectric sensor. In nature, any more than the absolute temperature (-273o) of the object generates infrared radiation, infrared energy release wavelength objects at different temperatures are also different. The body has a constant body temperature. There are differences with the ambient temperature. When the body moves, changes the difference by the pyroelectric sensor detected by Finel lens, thus the output alarm signal.

3、微波探測(cè)器:應(yīng)用的是多普勒效應(yīng)原理.在微波段,當(dāng)以一種頻率發(fā)送時(shí),發(fā)射出去的微波遇到固定物體時(shí),反射回來的微波頻率不變,即f發(fā)=f收,探測(cè)器不會(huì)發(fā)出報(bào)警信號(hào).當(dāng)發(fā)射出去的微波遇到移動(dòng)物體時(shí),反射回來的微波頻率就會(huì)發(fā)生變化,即f發(fā)≠f收,此時(shí)微波探測(cè)器將發(fā)出報(bào)警信號(hào).

3, microwave detector is: the application of the principle of Doppler effect. In the microwave region, as in a frequency transmission, microwave emission out of the fixed objects encountered when the reflected microwave frequency is f =f unchanged, the detector will not send alarm signal. When the microwave transmitted across the mobile object, microwave frequency will the reflected changes, namely F and F, the microwave detector will send alarm signals.

4、震動(dòng)探測(cè)器:震動(dòng)探測(cè)器是以探測(cè)入侵者進(jìn)行各種破壞活動(dòng)時(shí)所產(chǎn)生的振動(dòng)信號(hào)作為報(bào)警依據(jù),例如,入侵者在進(jìn)行鑿墻、鉆洞、破壞ATM、撬保險(xiǎn)柜等破壞活動(dòng)時(shí),都會(huì)引起這些物體的振動(dòng).以這些振動(dòng)信號(hào)來觸發(fā)報(bào)警的探測(cè)器就稱為振動(dòng)探測(cè)器.

4, vibration detector: vibration detector is to detect an intruder alarm as the basis, the vibration signal generated by a variety of activities such as destruction, for intruders in Zaoqiang, holes, damage ATM, open safes and sabotage, will cause the vibration of these objects. The vibration signal to trigger the alarm detector known as the vibration detector.

5、雙元紅外探測(cè)器和四元紅外探測(cè)器:把2個(gè)性能相同,極性相反的熱釋電傳感器整合在一起的具有兩個(gè)探測(cè)源的探測(cè)器就是雙元探測(cè)器.把4個(gè)性能相同,極性相反的熱釋電傳感器整合在一起的具有四個(gè)探測(cè)源的探測(cè)器就是四元探測(cè)器.

5, dual infrared detector and four element infrared detector: the same 2 performance, the polar opposite of the pyroelectric sensor together with two source detector is a dual detector. The same 4 performance, the polar opposite of the pyroelectric sensor together with four detection the source of the detector is four yuan detector.

6、雙鑒探測(cè)器:為了克服單一技術(shù)探測(cè)器的缺陷,通常將2種不同技術(shù)原理的探測(cè)器整合在一起,只有當(dāng)2種探測(cè)技術(shù)的傳感器都探測(cè)到人體移動(dòng)時(shí)才報(bào)警的探測(cè)器稱為雙鑒探測(cè)器.市面上常見的雙鑒探測(cè)器以微波+被動(dòng)紅外.

6, detector: in order to overcome the defects of single detector, usually 2 different technical principle of detector together, only when the 2 sensor detection technology is to detect human mobile alarm detector called the detector. The detector common market with the microwave and passive infrared.

7、三鑒探測(cè)器和四鑒探測(cè)器:三鑒探測(cè)器只是國內(nèi)一些廠家和銷售商宣傳的噱頭,以微處理器技術(shù)作為一種探測(cè)方式.實(shí)際上這只能算三技術(shù)探測(cè)器.

7, three detector detector and four detector detector: three detector is just a gimmick publicizing by some domestic manufacturers and sellers, taking microprocessor technology as a detection way. In fact, it can only be regarded as three technology detector.
