随着半导体电子元件的不断发展,现阶段人们家庭智能防盗报警器不管在工艺和产品质量方面都有很大的提高,同时在价格方面也出现了大幅的下降,现在价格大概到千元左右,这给平常家庭使用家庭防盗报警器的使用带来了很大的便利.但是常见的家庭防盗报警器都有哪些分类呢?济南瑞安电子有限公司给出了详细的介绍:
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、主动红外探测器:由红外发射器和红外接收器组成.红外发射器发射一束或多数经过调制过的红外光线投向红外接收器.发射器与接收器之间没有遮挡物时,探测器不会报警.有物体遮挡时,接收器输出信号发生变化,探测器报警.
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、被动红外探测器:中有2个关键性元件,一个是菲涅尔透镜,另一个是热释电传感器.自然界中任何高于温度(-273o)的物体都会产生红外辐射,不同温度的物体释放的红外能量波长也不同.人体有恒定的体温,与周围环境温度存在差别.当人体移动时,这种差别的变化通过菲涅尔透镜被热释电传感器检测到,从而输出报警信号.
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、微波探测器:应用的是多普勒效应原理.在微波段,当以一种频率发送时,发射出去的微波遇到固定物体时,反射回来的微波频率不变,即f发=f收,探测器不会发出报警信号.当发射出去的微波遇到移动物体时,反射回来的微波频率就会发生变化,即f发≠f收,此时微波探测器将发出报警信号.
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、震动探测器:震动探测器是以探测入侵者进行各种破坏活动时所产生的振动信号作为报警依据,例如,入侵者在进行凿墙、钻洞、破坏ATM、撬保险柜等破坏活动时,都会引起这些物体的振动.以这些振动信号来触发报警的探测器就称为振动探测器.
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、双元红外探测器和四元红外探测器:把2个性能相同,极性相反的热释电传感器整合在一起的具有两个探测源的探测器就是双元探测器.把4个性能相同,极性相反的热释电传感器整合在一起的具有四个探测源的探测器就是四元探测器.
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、双鉴探测器:为了克服单一技术探测器的缺陷,通常将2种不同技术原理的探测器整合在一起,只有当2种探测技术的传感器都探测到人体移动时才报警的探测器称为双鉴探测器.市面上常见的双鉴探测器以微波+被动红外.
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、三鉴探测器和四鉴探测器:三鉴探测器只是国内一些厂家和销售商宣传的噱头,以微处理器技术作为一种探测方式.实际上这只能算三技术探测器.
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.
