(54) УСТРОЙСТВО дл МНОГОТОЧЕЧНОЙ СИГНАЛИЗАЦИИ(54) DEVICE FOR MULTIPOINT SIGNALING

Изобретение относитс к автоматической сигнализации, в .частности к устройствам дл проверки исправности сигнальных ламп, питаемых посто нным или переменным током, и может быть использовано при автоматизации и диспетчеризации сложных технологических процессов,The invention relates to automatic signaling, in particular, to devices for checking the operability of signal lamps powered by direct or alternating current, and can be used in the automation and dispatching of complex technological processes,

Известно устройство дл многоточечной сигнализации, содержащее кнопку контрол , полупроводниковые диоды и подключенные к сигнальным лампам контакты датчиков -f .A device for multipoint signaling is known, containing a control button, semiconductor diodes and sensor contacts -f connected to signal lamps.

Недостатком устройства вл етс отсутствие проверки исправности.A disadvantage of the device is the lack of a health check.

Наиболее близким по технической сущности к предлагаемому вл етс устройство дл многоточечной сигнализации , содержащее диоды, одни выводы которых подключены -к контролируемым лампам, другие - к групповым шинам, указатели неисправности через одни дополнительные диоды подключены к групповым шинам, ко-торые через другие дополнительные диоды подключены к замыкающей контрольной кнопке 2,The closest in technical essence to the present invention is a device for multipoint signaling, comprising diodes, some of which are connected to controlled lamps, others to group buses, fault indicators through one additional diodes connected to group buses, which through other additional diodes connected to the closing control button 2,

Недостатком устройства вл етс то, что при повреждении одного из диодов происходит ложное загораниеThe disadvantage of the device is that if one of the diodes is damaged, a false fire occurs.

сигнальных ламп и, кроме того, сложно определить , какой из диодов неисправен.signal lamps and, in addition, it is difficult to determine which of the diodes is faulty.

Цель изобретени - расширение функциональных возможностей и повышение надежности устройства.The purpose of the invention is to enhance the functionality and increase the reliability of the device.

Поставленна цель достигаетс тем, что в устройство дл многоточечной сигнализации, содержащее сиг10 нальные лампы, первый вывод каждой из котор ых через закыкающий контакт соответствующего датчика подключен к первой шине источника питани , котора соединена с переключающим This goal is achieved by the fact that in a device for multipoint signaling containing signaling lamps, the first output of each of them through the snapping contact of the corresponding sensor is connected to the first power supply bus, which is connected to the switching

15 контактом первой контрольной кнопки, введены тиристоры, втора контрольна кнопка, две контрольные лампы, кнопка сброса, вторые выводы сигнальных ламп через кнопку сброса соединены с 15 by the contact of the first control button, the thyristors are entered, the second control button, two control lamps, the reset button, the second terminals of the signal lamps are connected to the reset button through

20 второй шиной источника питани , котора через вторую контрольную кнопку подключена к управл ющим электродам тиристоров, анод каждого из которых соединен с первым выводом соответствующей сигнальной лампы, катоды тиристоров подключены к замыкающему контакту первой контрольной кнопки, первому выводу первой контрольной лампы и первому выводу второй контрольной 20 by a second power supply bus, which is connected via the second control button to the thyristor control electrodes, the anode of each of which is connected to the first output of the corresponding signal lamp, the thyristor cathodes are connected to the make contact of the first control button, the first output of the first control lamp, and the first output of the second control

Claims

30 lamp, the second terminal of which is connected to the first power supply bus, the second bus of which is connected to the second terminal of the first control lamp. The drawing shows the basic electrical circuit. The proposed device includes sensors 1, alarm lights 2, typCCTop 3, control buttons 4 and a reset button 6, control lamps 7 and 8, and a power supply 9. The device works as follows. In the operating mode, the warning lamps are switched on through the corresponding contacts of sensors 1, Lamps 7 to 8 are connected in series, therefore, half of the voltage is supplied to each of them. Thyristors 3 provide for the isolation of circuits during the breakdown of any of them and the closure of the contacts of sensors 1. When the signal lamps are checked for health, buttons 4 are simultaneously closed and Button 4 shunts lamp 8, it goes out and there is a full working voltage applied to lammat 7. Through the closing contact of the button 5, the voltage is applied to the control electrodes, thyristors 3. The thyristors 3 are unlocked, and power is supplied to the signal 2. In devices powered by direct current, after checking the health of the signal lamps 2, you must press the button 6. Lamps 7 and 8 are similar in electrical parameters to signal lamps 3. When the thyristor 3 is broken and contact 1 is closed, the brightness of the lamp 7 increases, and the lamp 8 goes out, while the contact is open once again, the brightness of the lamp 8 increases and the brightness of the lamp 7 decreases. Thus, the test lamps 7 and B signal the occurrence of a malfunction in the device for checking the warning lamps. A faulty thyristor is detected by closing button 4 when lamp 7 is on. When button 5 is closed, lam pa pas 8 goes out and lamp 7 and lamp 2 in the circuit of the faulty thyristor light up. During the breakdown of the thyristor 3, the signaling circuit remains operable, since when the contact of the signaling sensor is closed, the signal lamp 2 receives the full operating voltage. Thus, a faulty thyristor does not affect the flow of information from the monitored object and not its. The invention The device for multi-point gnalisation, containing signal luminaires, the first output of each of which, through the closing contact of the corresponding sensor, is connected to the first power supply bus which is connected to the switching contact of the first control button, which is temporally functional and improves device reliability , thyristors, a second control button, two control lamps, a reset button, the second outputs of signal lamps through the soy reset button are entered into it. A dinene with a second power supply bus, which is connected via a second control button to the thyristor control electrodes, the anode of each of which is connected to the first output of the corresponding signal lamp, and the thyristor cathodes connected to the fade / contact of the first control button ;. the first output of the first control lamp, the first output of the second control lamp, the second output of which is connected to the first power supply bus, the second bus of which is connected to the second output of the first control lamp.
