Abstract

FIELD: security systems. SUBSTANCE: device has emitter with lens, receiver with lens, which has narrow-band interference filter. Emitter and receiver are connected to control unit, which has preliminary amplifier, master oscillator, pulse detector, alarm unit. In addition device has shaping protection grid for monitored area, system of reflectors, which last one is regulated with respect to slope. Reflectors serve for directing beams to receiver. Emitter with lens and receiver with lens are located in same plane and are located on same rotation bear which detects angle α for emission to system of reflectors. Angle a determines required density of protection grid of monitored area and belong to range of 0<α<90. Device operates as follows. Sharp beam from emitter with lens which is located on rotation bear enters reflector at angle α. Beam is reflected from reflector to reflector and so on until after multiple reflection it reaches regulated reflector which sends beam to receiver through narrow-band filter and further to control unit which has preliminary amplifier, master oscillator, pulse detector, alarm unit, which generates required signal. When intruder or object enters arbitrary point of monitored area, flow emitted by emitter is broken and alarm unit generates signal which corresponds to function of detection unit (alarm, locking final controls, an so on). Device may be used in security devices for counting number of persons or objects who intersect monitored area as well as in protecting systems which protects working area against prohibited access of persons or objects in said areas. EFFECT: monitored area is shaped by single functional channel.

Изобретение может быть использовано в системах охранной сигнализации, системах подсчета лиц или объектов, пересекающих контролируемую зону, а также в предохранительных системах защиты рабочих зон различного оборудования от несанкционированного попадания лиц или объектов в эти зоны. Устройство позволяет сформировать контролируемую зону только одним функциональным каналом, путем введения системы отражателей (в отличие от существующих сложных и громоздких многоканальных устройств обнаружения). Устройство обнаружения содержит излучатель с объективом, приемник излучения с объективом, снабженный с целью повышения помехозащищенности узкополосным интерференционным фильтром, связанные со схемой управления, включающей предварительный усилитель, задающий генератор, импульсный детектор и блок сигнализации, а также формирующую защитную сетку контролируемой зоны систему отражателей, последний из которых, регулируемый по наклону, для направления отраженного потока излучения на приемник излучения. При этом излучатель с объективом и приемник с объективом расположены в одной плоскости и установлены на общем поворотном устройстве, задающем угол ввода излучения в систему отражателей, который определяет необходимую плотность защитной сетки контролируемой зоны и может принимать значения от 0 до 90o.The invention can be used in alarm systems, counting systems of persons or objects crossing a controlled area, as well as in safety systems for protecting work areas of various equipment from unauthorized persons or objects entering these zones. The device allows you to create a controlled area with only one functional channel, by introducing a system of reflectors (in contrast to the existing complex and bulky multi-channel detection devices). The detection device comprises an emitter with a lens, a radiation receiver with a lens, equipped with a narrow-band interference filter to increase noise immunity, associated with a control circuit including a preamplifier, a master oscillator, a pulse detector and an alarm unit, and a reflector system forming the protective grid of the controlled zone, the latter of which, adjustable in slope, for directing the reflected radiation flux to the radiation receiver. In this case, the emitter with the lens and the receiver with the lens are located on the same plane and are mounted on a common rotary device that sets the angle of radiation input into the system of reflectors, which determines the necessary density of the protective grid of the controlled area and can take values from 0 to 90 o .
