Abstract

The invention relates to automatic signaling with individual light and general sound alerts and can be used in systems for centralized control of production processes. The aim of the invention is to enhance the functionality of the device by ensuring control of the integrity of the tires. The device contains a power source 1, blinks 2 and 3, acknowledgment buttons 4 and 5, control button 6, indication cells 7, alarm block 8. Each indication cell 7 is made of an acknowledgment relay 19, a signal lamp 17, a switching contact 18 of the sensor, and diodes 9-16. The device works as follows. When the switching contact 18 of the sensor is triggered, the signal lamp 11 and the signal unit 8 are switched on in a pulsed mode with a single duty cycle. When the signal is acknowledged, the signal unit 8 is turned off, and the signal lamp 17 goes into a steady glow mode. When the sensor returns to its initial state, the signal lamp 17 and the signal unit 8 operate in a pulsed mode with a different duty cycle. When acknowledging, the signal lamp 17 and the signal unit 8 are turned off. If one bus of 2 or 3 blinks is interrupted, then when the sensor is triggered, only the warning light 17 turns on in a pulse mode. 1 Il. about (f C to; os wasps tfn her

Description

The invention relates to automatic alarms with individual light and general audible alarms and can be used in systems for centralized control of production processes, such as in coal mines.

The purpose of the invention is to expand the functional capabilities of the device by ensuring tire integrity monitoring.

The drawing shows a circuit diagram of the device.

The device for signaling the state of on-off objects contains a source of power 1, buses 2 and 3 blinking 5 buttons 4 and 5 of acknowledgment, button 6 of control, cell 7 of indication, block 8 of alarm. Each indication cell 7 is made of diodes 9-16, a signal lamp 17, a switching contact 18 of the sensor, an acknowledgment relay 19 with closing contacts 20 and 21, and a switching contact 22o. The alarm block 8 is made up of indicators 23 and 24 and sound alarms 25 and 26. Source 1 includes a pulse generator 27.

The device works as follows

In the initial state, the switch 18 of the sensor is in the

In the position shown in the drawing, the warning lamp 17 in the indication cell 7 is turned off and the acoustic warning devices 25 and 26 are disconnected in the alarm 8 block. When the sensor in the indication cell 7 is triggered, the warning lamp 17 is connected to the bus- 3 blinks to which it is simultaneously connected the buzzer 25 and the indicator 23 of the alarm unit 8 When you press the acknowledgment button 5 to turn on the acknowledgment relay 19 and become on the self-blocking. In this case, the switching contact 22 of the handshake relay 19 turns off the buzzer 25 and the indicator 23, and the warning lamp 17 in the indication cell 7 switches to steady light 5 as connected by the closing contact 20 of the handshake relay 19 and to the bus 2 blinks,,

When the sensor is disconnected, the signal lamp 17 of the alarm cell 7 remains connected only to the bus 2

gani ,, therefore, shines with flashing with; At the same time, an indicator 24 and an audible alarm 26 are connected through the indication cell 7 to the buses.

When the acknowledgment button 4 is pressed, the acknowledgment relay 19 is turned off and the device returns to its original state.

The check of indicators 23 and 24 and the audible alarms of the alarm unit 8 and the signal lamps 17 of the display cells 7 is carried out by the control button 6.

The prompt selection of a signal that a sensor is turned off or turned on is made due to the fact that the signals received via buses 2 and 3 are flashing different from each other by the duty cycle.

When one of the tires 2 or 3 blinks when the sensor is triggered, the signal lamp 17 of the alarm cell 7 turns on the blinking mode and the unit. 8 alarm is disabled.
