Abstract

FIELD: security devices, instruments. SUBSTANCE: device has additional filtration and amplification channel, which input is connected to output of detector and which output is connected to signal processing circuit. Each signal processing circuit has comparator, integrator and Schmidt- flip-flop, which are connected in series. Outputs are connected to final-control devices. Output of each Schmidt-flip-flop in circuit having lesser threshold of comparator is connected to input of integrator in signal processing circuit with greater comparator threshold. Device may be used in alarm devices using capacitor antenna as sensitive element. It provides possibility of protection of rooms, safes, metal constructions, windows and doors. EFFECT: increased stability to noise, stability against contingent motion around object, stability in thunder storm conditions, operations under changes in weather, exclusion of additional tuning.

Изобретение относится к техническим средствам охраны, а именно к тревожной сигнализации с применением в качестве чувствительного элемента устройства наружной антенны емкостного типа, и может быть использовано для защиты различных объектов, сейфов, металлических конструкций, оконных и дверных проемов зданий, а также в приборостроении. Задача изобретения - усовершенствование устройства для тревожной сигнализации емкостного типа, содержащего генератор, полосовой фильтр, который соединен с усилителем, и детектор. Согласно изобретению в устройство введен дополнительный канал фильтрации и усиления, вход которого подключен к выходу детектора, а выход - к цепям обработки сигнала, каждая из которых включает последовательно соединенные компаратор, интегратор и триггер Шмидта, выходы которых соединены с исполнительными устройствами, при этом выход каждого триггера Шмидта в цепи с меньшим порогом срабатывания компаратора соединен с входом интегратора в цепи обработки сигнала с большим порогом срабатывания компаратора. Устройство обладает повышенной помехозащищенностью, не реагирует на случайные приближения к охраняемому объекту, не реагирует на грозовую деятельность, сохраняет работоспособность при климатических изменениях, не требует дополнительных подстроек и регулировки аппаратуры.The invention relates to technical means of protection, namely to alarm using an external antenna of capacitive type as a sensitive element of the device and can be used to protect various objects, safes, metal structures, window and doorways of buildings, as well as in instrumentation. The objective of the invention is the improvement of the device for alarm capacitive type containing a generator, a bandpass filter that is connected to an amplifier, and a detector. According to the invention, an additional filtering and amplification channel is introduced into the device, the input of which is connected to the detector output, and the output to signal processing circuits, each of which includes serially connected comparator, integrator and Schmidt trigger, the outputs of which are connected to actuators, while the output of each Schmidt trigger in the circuit with a lower threshold for the comparator is connected to the input of the integrator in the signal processing circuit with a large threshold for the comparator. The device has increased noise immunity, does not respond to accidental proximity to a guarded object, does not respond to thunderstorm activity, maintains operability during climatic changes, does not require additional adjustments and equipment adjustment.
