Устройство содержит источник питания с положительной 1 и отрицательной 2 клеммами, кнопку 3 контроля и сигнальные ячейки 4—1 - 4-п . Каждая из сигнальных ячеек 4-1 - 4 - η содержит ₃₀переключающий контакт 5 датчика с вы-выводами 6-8, светодиоды 9 и 10, транзисторы 11 и 12, резисторы 13-16.The device contains a power source with positive 1 and negative 2 terminals, a control button 3 and signal cells 4-1 - 4-p. Each of the signal cells 4-1 - 4 - η contains ₃₀ switching contact 5 of the sensor with pins 6-8, LEDs 9 and 10, transistors 11 and 12, resistors 13-16.

Устройство для сигнализации положения механизма работает следующим образом. ³⁵ A device for signaling the position of the mechanism operates as follows. ³⁵

В рабочем режиме при открытых или закрытых положениях контактов 5 через вывод 7 или 8 и вывод 6 подаются сигналы соответствующих полярностей и подсвечиваются светодиоды 9 (закры- ⁴⁰того положения механизма) или светодиоды 10 (открытого положения). Например, если в первой сигнальной ячейкеIn the operating mode, with the open or closed positions of contacts 5, signals of the corresponding polarities are fed through terminal 7 or 8 and terminal 6, and LEDs 9 (closed ^{40 of} that mechanism position) or LEDs 10 (open position) are illuminated. For example, if in the first signal cell

4—1 контакт 5 находится в состоянии, при котором замкнуты выводы 6 и 7, ⁴⁵ то в этой ячейке 4-1 подсвечивается светодиод 9 закрытого положения механизма по следующей цепи: поло жите голая клемма 1 источника питания - размыкающий контакт кнопки 3 контроля - зам- ^5,0кнутые выводы 7-6 контакта 5 в сигнальной ячейке 4-1 - резистор 13 - светодиод 9 — участок коллектор-эмиттер открытого транзистора 12 - отрицательная клемма 2 источника питания. Откры- ⁵⁵тое состояние транзистора 12 обеспечивается выбором сопротивления резистора 14, которым определяется величина тока базы транзистора 12. Необходимая в каждом конкретном случае величина прямого тока, протекающего через светодиод 9, от которого зависит важнейший параметр светодиода 9, яркость свечения определяется выбором сопротивления резистора 13.4-1, pin 5 is in a state in which terminals 6 and 7, ^{45 are} closed, then in this cell 4-1 the LED 9 of the closed position of the mechanism is illuminated along the following circuit: put the bare terminal 1 of the power source - NC contact of button 3 of the control - Deputy - ^5.0 bent conclusions 7-6 of contact 5 in the signal cell 4-1 - resistor 13 - LED 9 - section of the collector-emitter of the open transistor 12 - negative terminal 2 of the power source. Toe transistor ⁵⁵ open 12 condition provided by selecting the resistance of the resistor 14 which determines the magnitude of the base current of the transistor 12. The required in each particular case, the magnitude of direct current flowing through the LED 9, which determines the most important parameter of the LED 9, the brightness is determined by the resistance of resistor 13, one for .

Если, например, в сигнальной ячейке 4-η контакт 5 находится в состоянии, при котором замкнуты диоды 6 и 8, то в указанной ячейке 4—η подсвечивается светодиод 10 (открытого положения механизма) по следующей цепи: положительная клемма 1 источника питания резистор 16 в сигнальной ячейке 4- п светодиод 10 - участок коллектор-эмиттер открытого транзистора 11 - замкнутые выводы 6-8 контакта 5 - размыкающий контакт кнопки 3 контроля - отрицательная клемма 2 источника питания. Открытое состояние транзистора 11 обеспечивает резистор 15, а величина прямого тока через светодиод 10 определяется резистором 16.If, for example, in signal cell 4-η, pin 5 is in a state in which diodes 6 and 8 are closed, then LED 10 (open position of the mechanism) is illuminated in the indicated cell 4 — η along the following circuit: positive terminal 1 of the power supply resistor 16 in the signal cell 4-p, LED 10 - collector-emitter section of the open transistor 11 - closed terminals 6-8 of contact 5 - opening contact of control button 3 - negative terminal 2 of the power source. The open state of the transistor 11 provides a resistor 15, and the magnitude of the direct current through the LED 10 is determined by the resistor 16.

При переходе механизма от закрытого к открытому положению, когда контакт 5 находится в нейтральном положении, транзисторы 11 и 12 включаются последовательно, подсвечиваются одновременно оба светодиода 9 и 10 по следующей' цепи: положительная клемма 1 — источника питания - резистор 16 - светодиод 10 - участок коллектор - эмиттер открытого транзистора 11 - резистор 13 - светодиод 9 - участок коллектор - эмиттер открытого транзистора 12 - отрицательная клемма 2 источника питания. Следовательно, одновременная подсветка в рабочем режиме обоих светодиодов 9 и 10 в сигнальной ячейке 4 обеспечивает визуальный контроль переходного режима работы механизма.When the mechanism moves from closed to open position, when pin 5 is in the neutral position, transistors 11 and 12 are turned on in series, both LEDs 9 and 10 are illuminated simultaneously along the following 'circuit: positive terminal 1 - power supply - resistor 16 - LED 10 - section collector - emitter of an open transistor 11 - resistor 13 - LED 9 - section collector - emitter of an open transistor 12 - negative terminal 2 of the power source. Therefore, simultaneous illumination in the operating mode of both LEDs 9 and 10 in the signal cell 4 provides visual control of the transient mode of operation of the mechanism.

В режиме контроля исправности светодиодов следует нажать кнопку 3 контроля. Размыкающимися контактами кнопки 3 контроля все контакты 5 отключаются от источника питания. При этом, как и при переходном режиме работы механизма, транзисторы 11 и 12 в каждой из ячеек 4-1 - 4-п включаются последовательно, поэтому в каждой из ячеек 4-1 - 4-п также одновременно подсвечиваются оба светодиода 9 и 10.In the LED health monitoring mode, press the control button 3. The opening contacts of the control button 3, all contacts 5 are disconnected from the power source. At the same time, as in the transition mode of the mechanism, transistors 11 and 12 in each of the cells 4-1 - 4-p are connected in series, therefore, in each of the cells 4-1 - 4-p, both LEDs 9 and 10 are also simultaneously illuminated.

Надежность устройства повышается за счет того, что светодиоды 9 и 10 включены в цепи коллекторов транзисторов 12’ и 11 последовательно с токоограничивающими резисторами 13 й 16. В зависимости от величины напряженияThe reliability of the device is increased due to the fact that the LEDs 9 and 10 are connected to the collector circuits of transistors 12 ’and 11 in series with current-limiting resistors 13th 16. Depending on the voltage

995106 6 источника питания выбираются сопротив- i ления токоограничиваюших резисторов 13 и 16, которые определяют подсветку светодиодов 9 и 10 с требуемой яркостью свечения. 5995106 6 of the power source, the resistances of current-limiting resistors 13 and 16 are selected, which determine the illumination of LEDs 9 and 10 with the required brightness. 5

Расширение функциональных возможкостей предлагаемого устройства за счет визуальной локализации неисправных светодиодов обеспечивается введением в каждую сигнальную ячейку двух транзис- 10 торов и резисторов. При этом, если в одном из светодиодов какой-то ячейки возникает неисправность типа о^рыв, то в режиме контроля исправности последБ)вательная цепь питания второго (исправ- 15 ного) светодиода не нарушается. Второй (исправный) светодиод подсвечивается через участок эмиттер - коллектор своего транзистора и переход эмиттер - ба- * за другого транзистора (коллекторная 20 цепь этого транзистора разорвана неиоправным светодиодом). Таким образом, именно неисправный светодиод - один неподсвеченный - визуально определяется. Если же в одном из светодиодов 25 какой-то ячейки возникает неисправность типа короткое замыкание, то в режиме контроля исправности короткозамкнутый (пробитый) светодиод не оказывает шунтирующего влияния на другие цепи. Из- jq меняется только ток коллектора соответствующего транзистора, но в целом состояние насыщения этого транзистора не изменяется (это достигается соответствующим выбором параметров). Таким образом, неисправный (короткозамкнутый) светодиод и в этом случае визуально определяется. .The expansion of the functional capabilities of the proposed device due to the visual localization of faulty LEDs is provided by the introduction of two transistors and resistors into each signal cell. At the same time, if in one of the LEDs of a certain cell a malfunction of the breakaway type occurs, then in the serviceability control mode the serial power supply circuit of the second (operational) LED is not disturbed. The second (serviceable) LED is highlighted through the emitter – collector section of its transistor and the emitter – ba * transition for another transistor (the collector 20 circuit of this transistor is interrupted by a faulty LED). Thus, it is a faulty LED - one unlit one - that is visually detected. If in one of the LEDs 25 of a certain cell a fault occurs such as a short circuit, then in the health monitoring mode the short-circuited (broken) LED does not have a shunt effect on other circuits. From jq, only the collector current of the corresponding transistor changes, but in general the saturation state of this transistor does not change (this is achieved by an appropriate choice of parameters). Thus, a faulty (short-circuited) LED is visually detected in this case too. .

It is known a device for signaling the position of a mechanism, comprising cells of two signal lamps, one of whose terminals is connected via diodes to one end of a communication line, the other end of which is connected to the first contacts of a switch, a current source1, a closing key, and a current source. cells were wired with a secondary winding parallel to the first secondary winding by another output of the first signal lamp and a second pin and switch, and parallel to the second secondary winding of a trans (1 hr cells are connected by another output of the second signal lamp and the third contact of the switch, the initial output of the second secondary winding and the final output of the first secondary winding are connected via a C 3 key. Device drawback is low reliability and limited functionality. The device for signaling the position of the device is closest to the proposed one. containing a power source, the terminals of which through the control button are connected to the first and second switch of the alarm contact nuts, each of which also comprises two LEDs 2. The drawbacks of the device are low reliability and limited functionality. The purpose of the invention is to increase the accuracy and expand the functionality of the device for signaling the position of the mechanism. The goal is achieved by the fact that in the device for signaling the mechanism, containing a power source, the terminals of which through the control button are connected to the first and second switches of the switch contact of the signal cell sensor, each of which also contains two LEDs, into each signal cell Two transistors and four resistors are introduced, and the third output of the switching contact of the sensor is connected through the first resistor to the base of the first transistor, in series with the second resistor and Pervy LED - with the collector of the first transistor and directly with the emitter of the second transistor, the base of which is through the third resistor, and the collector is connected through the second LED and the fourth resistor in series to one terminal of the power supply, and the emitter of the first transistor is connected to another source terminal Pi In the drawing A schematic diagram of the device for signaling the position of the mechanism is shown. . The device contains a power source with positive 1 and negative 2 terminals, control button 3 and signal cells 4-1 - 4-p. Each of the signal cells 4-1 -4-p contains a switching contact 5 of the sensor with outputs 6-8, LEDs 9 and 1O, transistors 11 and 12, resistors 13-16. The device for signaling the position of the mechanism works as follows. In the operating mode, with the open or closed positions of the contacts 5, the outputs 7 or 8 and the output 6 are given signals of the respective polarities and the LEDs 9 (closed position of the mechanism) or the LEDs 10 (open position) are illuminated. For example, if in the first signal cell 4-1, pin 5 is in a state in which pins 6 and 7 are closed, then in this cell 4-1, the LED 9 of the closed position of the mechanism along the following circuit is illuminated: positively. power supply - Ramakayuschy contact of the control button 3 - closed 7-6 of pin 5 in the CPN 4-1 cell - resistor 13 - LED 9 - collector-emitter section of the open transistor 12 - negative terminal 2 of the power supply. The open state of transistor 12 is provided by selecting the resistance of the resistor 14, which determines the base current of transistor 12. In each case, the amount of direct current flowing through the LED 9, on which the most important parameter of the LED 9 depends, is determined by the choice of resistance of the resistor 13. If, for example, in the signal cell 4-n pin 5 is in the state in which diodes 6 and 8 are closed, then in the indicated cell 4-n the LED 1O (open position of the mechanism) is illuminated about the next chain. positive terminal 1 of the power supply - resistor 16 in the signal cell 4 - n - led 10 - collector-emitter section of the open transistor 11 - short terminals 6–8 of pin 5 - disconnecting pin 3 of the control - from the power source. picnic terminal The open state of transistor 11 is provided by resistor 15, and the amount of direct current through LED 10 is determined by resistor 16. When the mechanism goes from closed to open when contact 5 is in the neutral position, transistors 11 and 12 turn on in series, are lit simultaneously both LEDs 9 and 10 along the following circuit: power supply terminal 1 is positive - resistor 16 - LED 10 - collector section - emitter of an open transistor 11 - resistor 13 - LED 9 - collector section - em transistor open tter 12 - negative power source terminal 2. Consequently, the simultaneous illumination in operating mode of both LEDs 9 and 10 in the signal cell 4 provides visual control of the transition mode of the mechanism. In the mode of monitoring the health of LEDs, press the button 3 control. Opening the contacts of the control button 3, all the contacts 5 are disconnected from the power source. In this case, as in the transitional mode of operation of the mechanism, transistors 11 and 12 in each of the cells 4-1 to 4-n are connected in series, therefore both LEDs 9 and 10 are simultaneously illuminated in each of 4-1 -4-n. Reliability devices are increased due to the fact that LEDs 9 and 10 are included in the collector circuits of transistors 12 and 11 in series with current limiting resistors 13 and 16. Depending on the supply voltage, the resistances of current-limiting resistors 13 and 16 are selected, and the angles determine the illumination of the power supply in 9 and 1O with a required glow of light. The expansion of the functional devices of the proposed device due to the visual localization of faulty network diodes is ensured by introducing two transiators and resistors into each signal cell. In this case, if in one of the LEDs of some kind of 5peaks a type malfunction occurs, then in the monitoring mode of operation, the successive power supply circuit of the second (correcting) LED is not disturbed. The second (equal) LED6d is illuminated through the emitter-collector section of its transistor and the emitter-bgnz transition of another transistor (the collector circuit of this transistor is interrupted by an unbalanced light diode). Thus, it is a faulty LED - one unlighted - visually identified. is. If in one of the LEDs there is some kind of “short circuit” fault, the short-circuited (punctured) LED does not have a shunt effect on other circuits in the condition monitoring mode. Only the collector current of the corresponding transistor is changed, but in general the saturations of this transistor do not change (this is achieved by an appropriate choice of parameters). Thus, a faulty (short octane whip) LED is also visually detected in this case. Claims An apparatus for signaling the position of a mechanism, comprising a power source, the terminals of which a control button is connected to the first and second terminals of the switching contact of the signal cell, each of which is also two meters from the output diode, that, in order to improve reliability and expand the functional capabilities of the device, two transistors and four resistors are inserted into each signal cell, and the third output of the switching contact of the sensor is connected through the first resistor to the base the first transistor, through a series-connected second resistor and the first LED with the collector of the first transistor and directly with the emitter of the second transistor, whose base is through the third resistor, and the collector through the series-connected second LED and fourth resistor are connected to the same power supply terminal, and the emitter of the first transistor connected to another power supply terminal.
