Abstract

FIELD: banks where securities and bank-notes are to be identified. SUBSTANCE: device has signal sensor in the form of inductance coil with core and comparator whose first input is connected to reference-voltage supply and output, to executive device. Novelty is that identifying device is provided with rectangular-pulse generator loaded into series-connected inductance coil of signal and active resistor; common point between inductance coil and active resistor is connected through series-connected amplitude detector, high-frequency filter, and scaler to comparator second input. EFFECT: improved validity of identification, simplified circuit arrangement, facilitated procedure, and reduced labour consumption.

Изобретение относится к устройствам для распознавания подлинности банкноты или ценной бумаги и может быть использовано при разработке и изготовлении устройств контроля подлинности банкнот или ценных бумаг для использования в своей работе сотрудниками банковских учреждений. Предложенное техническое решение направлено на совершенствование электрической схемы устройства контроля подлинности, включающей в себя датчик сигнала в виде катушки индуктивности с сердечником и компаратор, к первому входу которого подключен источник опорного напряжения, а к выходу - исполнительное устройство. Отличительная особенность предлагаемой электрической схемы состоит в том, что она содержит генератор прямоугольных импульсов, нагруженный на последовательно соединенные катушку индуктивности датчика сигнала и активное сопротивление, при этом общая точка между катушкой индуктивности датчика сигнала и активным сопротивлением подключена через последовательно соединенные амплитудный детектор, фильтр верхних частот и масштабный усилитель к второму входу компаратора. Предлагаемое устройство контроля подлинности банкноты позволяет повысить достоверность контроля, упростить электрическую схему устройства, повысить технологичность контроля банкноты, а также снизить трудоемкость проводимых работ.The invention relates to devices for recognizing the authenticity of banknotes or securities and can be used in the development and manufacture of devices for controlling the authenticity of banknotes or securities for use in their work by employees of banking institutions. The proposed technical solution is aimed at improving the electrical circuit of the authenticity control device, which includes a signal sensor in the form of an inductor with a core and a comparator, to the first input of which a reference voltage source is connected, and an actuator is connected to the output. A distinctive feature of the proposed electrical circuit is that it contains a rectangular pulse generator loaded on a series-connected inductor of the signal sensor and active resistance, while the common point between the inductance coil of the signal sensor and active resistance is connected through a series-connected amplitude detector, high-pass filter and a large-scale amplifier to the second input of the comparator. The proposed device for controlling the authenticity of banknotes can improve the reliability of control, simplify the electrical circuit of the device, increase the manufacturability of banknote control, as well as reduce the complexity of the work.
