Intruder detector with infrared detection channels

摘要

The invention relates to the field of infrared technology, in particular to devices for controlling the movement of objects. The technical result - exclusion of false alarms the motion detector object-animal, and ensuring the reliability of object detection, people anywhere in the protected area. Also reduced economic cost and improved manufacturability of the device. Technical result is achieved due to the fact that the set of optical elements of the optical system of the upper part of the optical elements corresponds to the distal sector detection zone, the lower part of the optical elements corresponds to the neighbor detection zone sector, and intermediate optical elements disposed between the upper and lower part of optical elements correspond to adjacent sectors detection area that can cover all areas of sensitivity detection zone and the detection zone to eliminate "dead zones"; since the optical centers of the optical elements corresponding to different zones of the detection optical system, arranged in vertical rows, and the distance between the optical centers of the optical elements in each vertical row increases by taking into account the fact that the radiation energy of the upper part of the optical arrangement of elements to the bottom and are mounted object-animal anywhere in the protected area is going to only one optical element and the radiation energy of the object, the person who is in close or related sectors s detection zone, meets at least three optical elements and the radiation energy of the object-man, who is in a far sector of the detection area, meet at least two optical elements, so that the energy of a pet radiation focused on the receiver of infrared radiation, is always less than the human radiation energy focused infrared radiation at a receiver; due to the fact that the dimensions and accordingly the area of ​​optical elements are selected so that the radiation energy is collected by a single optical element from the object, the animal was less than the energy required for issuing an alarm signal, and the energy emission from the object person is collected several optical elements It was always greater than the energy required for the issuance of an alarm.
