Description

The invention relates to automation technology, in particular to multi-channel signaling devices with individual light and general sound notification. The aim of the invention is to expand the scope of the device by providing the automatic installation of the initial state. This is achieved by the fact that

in a device containing signaling channels, each of which the invention relates to an automation technique, namely to multi-channel signaling devices with individual light and general sound notification.

The aim of the invention is expanded. The application area of the device due to the provision of the automatic installation mode of the initial state.

The drawing shows a diagram of the scheme of the transport system.

The device contains channels 1 alarm, each of which is made of elements OR 2-4, triggers

None of the sensor, two triggers, amplifier and signal lamp, a common element OR, a buzzer, a pickup button, a control button and a pulse generator, three OR elements, four AND elements, the NOT element, a single vibrator and a pulse shaper are entered into each alarm channel. When the contact of the sensor is opened, the signal lamp glows evenly and the buzzer turns on. By pressing the pickup button, the buzzer will turn off. After closing the sensor contact, the device returns to its original state. R

When closing the sensor contact to ®

5 and 6, elements 7-10, the one-shot 11, the element NO 12, the amplifier 13, the warning lamp 14, the sensor 15 and the pulse shaper 16, the pulse generator 17, the OR element 18, the buzzer 19, the control button 20 and the removal button 21 signal.

The device works as follows.

When power is applied to

the device circuit at the output of the shaper 11 pulse forms a pulse that through the element OR 4

enters the input of the one-shot 11, generating a short pulse, which is fed to the inputs of the flip-flops 5 and 6, setting the trigger 5 to the zero state, and the trigger 6 - in the unit.

In the initial state, the contact of the sensor 15 is closed, and the triggers 5 and 6 are set to the zero and one states, respectively, at the output of the element OR 2 there is a low level signal. At the same time at the output of the element OR 3 there is a low level signal and the signal lamp 14 is turned off. At the output of the element And 8 there is also a low level signal and the buzzer 19 is turned off.

When the contact of the sensor 15 (or the control button 20) opens at the output of the element OR 2, a high level signal appears, the trigger 5 is set to one, with the result that the warning lamp 14 is lit and the buzzer 19 turns on;

If the contact of the sensor 15 remains in the open state, then pressing the pickup button 21 triggers the trigger 6 to the zero state and the buzzer 19 turns off, and the warning light 14 continues to be a steady light. When the contact of the sensor 15 returns to its original state after the damage is eliminated, a high level signal appears at the output of the element 12, which, through the element 9, together with the signal from the output of the trigger 6, enters the input of the one-vibrator 11, which produces a short pulse that sets the trigger 6 to one , and the trigger 5 - in zero. As a result, the warning lamp 14 is turned off and the device is again ready for operation.

When the contact of the sensor 15 returns to the closed state, before pressing the button 21, the signal is removed at the output of the element 10, a high level signal appears from the output of the element NO 12. The trigger 5 is in a single state, therefore the pulses from the generator 17 pulses pass to the input of the element OR 3 and the warning light 14 blinks while the buzzer 19 is on. By pressing the button 21 pickup signal

the trigger 6 is transferred to the zero state, resulting in a high level signal from the input and output ₍ element NO 12 through the element AND 9 and through the element OR 4 enters the input of the one-vibrator 11. The single-oscillator 11 generates a pulse that resets the trigger 5 state and sets the trigger 6 in one state. The buzzer 19 is turned off, and the warning lamp 14 is turned off and the device is again ready for operation.
