Description

Изобретение относитс к оВпасти автоматинеской сигнализации с индивидуальным световым и общим повторным звуковым оповещением и может быть использовано при построении систем централизованного контрол судовых технических средств.The invention relates to an automatic signaling system with individual light and general repeated audible warning and can be used in the construction of centralized control systems for ship technical equipment.

Известно устройство дл многоточечной сигнализации, содер(жащее подключенные к источнику питани но числу точек сигнализации датчики С С-цепи, тиристоры, диоды и сигнал Ы1ые лампы, генератор им пульсов, кнопку кв1ггировани и звуковой сигнализатор 11,A device for multipoint signaling is known, containing (connected to the power source but to the number of signaling points sensors With a C-circuit, thyristors, diodes and an L1 signal, lamps, a generator of pulses, a switch button and a buzzer 11,

Наиболее близким к данному изобретению по технической сущности и достигаемому эффекту вл етс устройство дл многоточечной сигнализации, содержащее звуковой сигнализатор, генератор импупьс в , источник питани , кнопку кввтщюва- ни и сигнальные чейки, кажда из которых содержит контакт датчика, который подключен последовательно к репе квнти .рованЕ и первым замыкающим контактом sjoro реле - к источнику питани , диодThe closest to this invention in its technical essence and the effect achieved is a device for multi-point signaling, containing an audible alarm, an impulse generator, a power source, a push-button and signal cells, each of which contains a sensor contact that is connected in series to the turntable .Europe and the first closing contact sjoro relay - to the power source, the diode

и сигнальную лампу, подключенную через второй замыкающий контакт реле квитировани к источнику питани Г2Т.and a signal lamp connected via the second closing contact of the handshake relay to the G2T power source.

Недостатком этого устройства вл етс мала надежность.A disadvantage of this device is low reliability.

С целью повышени надежности устройства , в нем в каждую сигнальную чейку введено дополнительное реле, обмотка дополнительного репе подключена через контакт датчика и размыкающий контакт репе квитирован к источнику питани , сигнальна лампа подключена через первый замыкающий контакт дополнительного реле к (Генератору ш пульсов, замыкающие контакты дополнительного реле включены в цепь питани звукового сигнализатора.In order to increase the reliability of the device, an additional relay is inserted into each signal cell, an additional turnip winding is connected through the sensor contact and the turn-off contact is acknowledged to the power source, the signal lamp is connected through the first closing contact of the additional relay to (Pulse generator, additional contacts relays are included in the power supply circuit of the buzzer.

Claims

The device contains cells 1 connected in parallel, each of the second ones contains contact 2 of the sensor, a signal lamp 3, an acknowledgment relay 4, an additional relay 5, a razdyvayushchy drive 6, as well as a power source 7, an acknowledgment button 8, a pulse generator 9, a buzzer 10, the closing contacts 11, 12 of the relay 4, the opening contact 13 of the relay 4, the closing contacts 14, 15 of the relay 5. In the initial state, the relays 4 and 5 are both turned, the lamp 3 does not light, the warning alarm 10 is turned off. When the sensor contact 2 is closed, the relay 5 is activated and through the closing contact 15 turns on the buzzer 10, and through the closing contact 14 connects the signal lamp 3 to the blinking light generator 9. As a result, the signal lamp 3 flashes and a beep appears. By pressing the acknowledgment button 8, the development of DC 6 turns on the relay 4, the contact 13 is opened, and the contacts 11 and 12 are closed. The relay 5 is de-energized and the signal lamp 3 is connected via the closure contact 12 to the power supply 7. At the same time, the sound signal and the flashing of the lamp 3 stop, which is illuminated with a steady light until the corresponding sensor is flashing. When contact 2 of the sensor is opened, the signal lamp 3 goes out, as relay 4 is de-energized and contact 12 is opened; The coupling diode 6 is used to detect the operation of the switching on of the signal lamp 4, to which the signal from the contact 2 of the sensor 2 has just arrived, up to the moment when the acknowledgment button is turned on. The positive effect is that in the proposed device the relay contacts operate in a lightweight mode, which increases the service life of the relay and increases the reliability of the device as a whole. Apparatus of the Invention A multipoint alarm device comprising an audible alarm, a pulse generator, a power source, an acknowledgment button and signal cells, each of which contains a sensor contact that is connected in series to the acknowledgment relay and the first closing contact of this relay to the power source, a diode and a signal lamp , connect; via the second closing contact of the handshake relay to the power source, which is distinguished by the fact that, with an increase in the reliability of the device, an additional relay is inserted into each signal cell, the auxiliary relay coil is connected through the sensor contact and the break contact of the handshake relay to the power source, the warning lamp is connected via the first closing contact of the additional relay to the pulse generator, the second closing contacts of the additional relay are connected to the power supply circuit of the buzzer.
