SU1672495A1 - Alarm device - Google Patents

Abstract

The invention relates to signaling and can be used to protect various objects. The aim of the invention is to increase the functional reliability of the device. The purpose of the invention is achieved in that a device comprising a power source, a switch, a sensor, two inverters, a trigger and a key are inserted into a magnetic audio playback unit, an integrating element, a counter, two switches, two pulse shapers, an OR element, and I. When the sensor is triggered, the counting of pulses is resolved. If, for a predetermined time, the person opening the room using the first switch writes the code number to the counter, then an alarm is not generated. Otherwise, after a predetermined time has elapsed, the power of the magnetic sound recorder is turned on, which generates a speech alarm with information, for example, about the number of the opened room. The destruction of the sensor, switch, first switch after opening the room does not prevent the formation of an alarm signal. 1 il.

Description

The invention relates to the field of signaling and can be used to protect various objects.

The purpose of the invention is to increase functional reliability.

The drawing shows the functional diagram of the device for alarm.

The device contains a sensor 1, a switch 2, a switch 3, an integrating element 4, formers 5, 6 pulses inverter 7, element OR NOT 8, element AND 9, key 10, trigger 11, counter 12, switch 13, inverter 14, source 15 power and a magnetic sound recorder 16. Position 17 marked the wind coil of block 16.

The device works as follows.

In standby mode, the contact of sensor 1 is open, the contact of switch 2 is closed. At the outputs of the formers 5, 6 pulses - signal O. With the signal 1 from the output of the inverter 7, the counter 12 is held in the state 0 Key 10 by the signal O from the output of the element 9 and 9 is locked and the magnetic recording unit 16 is turned off.

When the door is released at the facility, the contact of sensor 1 closes. If the time of the closed contact state exceeds a certain value, for example, 0.1 s, then the signal, having passed through the integrating element 4, starts the pulse shaper 5, with the output signal of which the pulse shaper 6 is started.

pulse generated by myroppel 5 pulses, e.g. remains in the closed state. During this time, the person opening the room must press the switch 3 a certain number of times. At the same time, the pulses from the output of the trigger 11 are sent to the counting input of the counter 12 If the number of pulses corresponds to NIJ of the counter 12 at which the signal 1 is present at the output connected to the output of the switch 13 closed with its common terminal, a signal, after passing through an inverter 14, disables signal flow 1 through the AND gate 9, and consequently the unlocking of the key 10.

Otherwise, the shear formed by the pulse shaper 6, i.e. after 10 s, at the output of the element OR-NOT 8, signal 1 appears, which causes the signal 1 to appear at the output of the element AND 9 and unlocks the key 10. Through the public key 10, the power goes to the magnetic sound reproduction unit 16 The last plays voice information any content, such as house number and apartment opened, etc. The speech signal is transmitted for a time equal to the difference in the lengths of the pulses formed by the shaper 5 and 6 pulses. At the same time, the loudspeaker 17 of the block 16 reproduces. The introduction of magnetic sound recordings can be placed outside the protected room.
