Description
Technical field
The utility model relates to electronic anti-theft detector field, particularly a kind of infrared intrusion detector.
Background technology
In electronic anti-theft detector field, being widely used of infrared intrusion detector.Human body has constant body temperature, is generally 37 ℃, can send the infrared ray of specific wavelength 10UM left and right, and passive type infrared probe is to carry out work by the infrared ray of the 10UM left and right of detection human-body emitting.The infrared ray of the 10UM left and right of human-body emitting gathers on infrared induction source after strengthening by your optical filter of luxuriant and rich with fragrance mud.Infrared induction source adopts the pyroelectricity element containing two mutual serial or parallel connections conventionally, and two electric polarization directions making are just in time contrary.Ambient background radiation is released element to two heat and is almost had identical effect, makes its generation release electrical effect and cancels out each other, so the output of detector no signal.Once and have people to invade in search coverage, human infrared radiation focuses on by partial mirror, and is received by pyroelectricity unit, but the heat that two pyroelectricity units receive is different, pyroelectricity is also different, can not offset, and through signal, processes and reports to the police.
Current infrared intrusion detector on the market often adopts in order to improve detecting effect the method that sensitivity is heightened.The early stage range of sensitivity is generally 2-3 meter, has heightened now the meter to 7-8.Thereby this method can reach signal really amplifies the effect that expands reconnaissance range, but has also increased wrong report probability, its None-identified human body and toy, when constant temperature toy process reconnaissance range, also can produce false alarm.
Utility model content
The purpose of this utility model is to solve prior art when improving detecting sensitivity, the None-identified human body causing and short and small animal and increase the problem of false alarm probability.
For addressing the above problem, the utility model provides a kind of infrared intrusion detector, comprise body and main control unit, on described body, be provided with relay indicating light, also comprise the first infrared detection head and the second infrared detection head, described body has the first detecting window and the second detecting window, described the first infrared detection head and the second infrared detection head are arranged at internal body, and the position of corresponding the first detecting window of difference and the second detecting window, described the first infrared detection head arranges along the downward 30-40 degree of body vertical direction angle, described the second infrared detection head arranges along the downward 60-70 degree of body vertical direction angle.
Further, described the first infrared detection head is along the downward 30 degree angle settings of body vertical direction, and described the second infrared detection head is along the downward 60 degree angle settings of body vertical direction.
Further, described the first infrared detection head is positioned at the second infrared detection head top.
Further, on described body, be provided with mounting bracket, described mounting bracket is connected with body by connecting link, and one end of described connecting link is fixed on body, and the other end and the mounting bracket of described connecting link are hinged.
Further, on described body, be also provided with feeler switch.
