Description

DEVICE INDICATIONS

The invention relates to a pulse technique, in particular to an alarm technique, and can be used to lightly indicate the presence of triggering of sensors of various types in automation systems, in alarm systems.

Currently, to indicate the occurrence in the alarm systems, a signal processing unit (BOS) is used from the detector kit of the surface protective shock-contact IOZOZ-4 Window-5 LV2.403.057, see the catalog of security equipment used by private security; supplement to the journal Protection: service, technical means, economics, - SIC Protection GUBO MVL, Russia, 2000, p. 26 (1).

The disadvantage when using this signal processing unit is that it is designed to work only with a glass break sensor (DLS) and, when used with other types of sensors, reduces the noise immunity of the alarm system.

A device is also known, the so-called chipper from the kit of the security foot detector I0102-1 TU25-75450.003-88, used to indicate the fact of the sensor triggering. See the catalog of security equipment used by private security; supplement to the journal Protection: service, technical means, economics, - SIC Protection GUUVO Ministry of Internal Affairs, Russia, 2000, from 156 (1)

which is triggered by mechanical action on the pedal, which corresponds to the transmission of an alarm signal (message) to the central monitoring console.

The disadvantage of this device is that the aforementioned chipper is used with a sensor, the inclusion of which occurs upon mechanical impact and has a current to turn on the indication of the same order as the standby currents of the alarm system.

The purpose of the proposed utility model Display device is to provide:

- turning on the display when the contacts of the sensor actuator are opened by connecting the input circuit of the display device to these contacts;

-exclusions of the influence of the indication cascade on the operation of the alarm system due to the low currents of the input circuit, which are provided by the introduction of signal amplifier 3 and its optoelectronic coupling with input circuit 1 (see drawing of the proposed device);

-stable operation of the device without reducing the noise immunity of the alarm system when using the display device due to a short circuit of the input circuit in standby mode of this system;

- small overall dimensions of the proposed device.

The specified goal is achieved as follows.

Instead of a thyristor optocoupler in known devices, the proposed device uses a transistor optocoupler connected to the executive contacts of the sensor, a KS chain is introduced into the input circuit of the transistor optocoupler; The transistor optocoupler controls the thyristor of the indication cascade.

(and

- 2 it is possible to take a chipper from the kit of the detector of the foot guard Y0102-1 TU25-75450.003-88 according to the source of scientific and technical information (1) from 156.

The drawing shows a structural diagram of the proposed Display Device.

The proposed device consists of a transistor optocoupler containing an input circuit 1, an optoelectronic transformer 2, a signal amplifier 3; a thyristor cascade of indication 4 is connected to the transistor optocoupler.

The proposed display device can be performed on a printed circuit board measuring 30 mm x 30 mm, which will allow, if necessary, to use it in conjunction with a standard contact block KK-8. When using this utility model, its input circuit 1 is connected to the contacts of the sensor actuator.

The proposed display device operates as follows. When the contacts of the sensor actuator in the input circuit 1 open, the current flows, which, after amplifying the signal of the optocoupler signal 3, opens the thyristor of the indication cascade 4, which leads to the glow of the LED included in the anode circuit of the thyristor. The display mode is maintained until the power of the display device is turned off.
