Description

Formula infrared detector is inhaled to magnetism

Technical Field

The utility model relates to a home security technical field, concretely relates to formula infrared detector is inhaled to magnetism.

Background

Infrared detectors operate by detecting infrared light emitted by a human body. The detector collects external infrared radiation and then gathers the infrared radiation on the infrared sensor. Infrared sensors usually employ pyroelectric elements, which release electric charges when receiving infrared radiation temperature changes, and alarm is generated after detection processing. Such detectors are aimed at detecting body radiation. The radiation-sensitive element must be very sensitive to infrared radiation having a wavelength of around 10 μm. In order to be sensitive to infrared radiation of the human body, the radiation-exposed surface is usually covered with a special filter, so that environmental disturbances are significantly controlled. The infrared detector has a sensor including two pyroelectric elements connected serially or parallelly. And the two manufactured electric polarization directions are just opposite, and the environmental background radiation almost has the same effect on the two pyroelectric elements, so that the pyroelectric effects generated by the two pyroelectric elements are mutually counteracted, and then the detector has no signal output. Once an invader enters the detection area, the infrared radiation of the human body is focused through a partial mirror and then received by the pyroelectric elements, but the heat received by the two pyroelectric elements is different, the pyroelectric elements are also different and cannot be offset, and an alarm is given out through signal processing. The multi-view field is obtained by the reflection focusing formed by the multi-normal small mirrors and the light is condensed on the sensor, and the reflection optical system is called. The other type of the infrared sensor is a transmission type optical system, namely a lens-Fresnel lens which is combined by multiple surfaces and is focused on the infrared sensor through the Fresnel lens. It is noted that the infrared rays indicate several fields of view, and instead of infrared red infrared rays, the more fields of view, the more tight the control.

The traditional infrared detector installation is generally three types:

the first column type installation, the more popular pillar has two kinds of circular and square, the earlier popular pillar is the circular section pillar, the present situation is just the reverse, the square pillar is more and more popular in the engineering world. Mainly, the detector is arranged on the square pillar and does not rotate and is not easy to move. Besides, the wide selection of stainless steel, alloy and aluminum alloy sections is one of the advantages. Another way in the industry is to select angle steel as a strut, and if the effective pipe penetration and hidden laying of the wiring cannot be guaranteed, the method is not preferable if the wiring is exposed in the air. The key point is that the fixing of the supporting column must be firm and firm without displacement or shaking, so as to facilitate the installation and fortification and reduce false alarm.

Wall-mounted installation is at the leading edge of technology's initiative infrared detector manufacturer now on the theftproof market, can provide the infrared detector of 180 all-round corners of level, the corner more than 20 of pitching, for example ALEPH initiative infrared detector HA, ABT, ABF series product, can support the probe directly to install on building outer wall or enclosure, fence.

And thirdly, the detector is arranged on the channel according to a general principle of detector installation, the main function of the detector is to prevent people from passing illegally, and the position of the probe is generally more than 50cm away from the ground in order to avoid false alarm caused by pets, small animals and the like. The shading time should be adjusted to a faster position to quickly respond to illegal intrusion. The detector arranged on the enclosing wall has the main functions of preventing man-made malicious crossing, and can be installed on the top and installed on the side surface. The detector is arranged on the top, and the position of the probe is 25cm higher than the top of the fence and the enclosing wall, so that false alarms caused by birds, kittens and the like moving on the wall are reduced. The four-beam detector has stronger false alarm prevention capability than the two beams, which are stronger than the single beam. The side installation is to install the probe on the side of the fence or enclosure near the top, generally in the wall type, and is installed on the outside mostly. The mode can avoid the activity interference of birds and cats. Each has their own advantages or disadvantages, and engineers have their own preferences for each installation. The users should choose according to the characteristics of their buildings and the anti-theft requirements.

The infrared detectors are complex to install, need to be wired in the early stage, and are huge in size, and various voltage transformation units are built in the infrared detectors due to the adoption of a 220V power supply. Generally, professional construction and installation personnel are needed for installation, and individuals cannot debug and install the equipment. Also have the unit version in the market, similar camera is that, need connect an electric wire, adopts to put or the mode that the wall pasted, has destroyed the whole decoration effect in room, and equipment is also simple exposes outside, and is very unsightly.
