Description

Изобретение относитс к области электрооборудовани подвижного состава железных дорог и предназначено дл задани возбуждени т гового генератора тепловоза .The invention relates to the field of electrical equipment for railway rolling stock and is intended to specify the excitation of a locomotive traction generator.

Известно устройство задани возбуждени т гового генератора тепловоза, содержащее врем задающий элемент и источник преобразуемого сигнала, дешифратор , соединенный одним своим входом с выходом источника преобразу1 мого сигнала , счетчик, подключенный своим вгодом к выходу В; ем задаюшего элемента, и преобразователи код-аналог, св занные С выходом дешифратора- L--l A device for specifying the excitation of a locomotive traction generator is known, which contains the time setting element and the source of the signal to be converted, a decoder connected by one of its inputs to the output of the source of the signal to be converted, a counter connected to the output B of its own; I am the master element, and the code-analog converters associated with the output of the decoder- L - l

Недостатком данного устройства вл етс его сложность, привод ща к недостаточной надежности.The disadvantage of this device is its complexity, resulting in a lack of reliability.

Целью изобретени :ЯБл етс повышение надежности устройства.Purpose of the invention: Improving the reliability of the device.

Цель достигаетс тем, что устройство снабжено дифференцнруюшей цепочкой, под люченной своим входом к выходу врем задающего элемента, и последовательно соединенными элемоитом ИЛИ и фильтром , при этом другие входы дешифратора соединены соответственно непосредствен Но с выходом врем эадающего эйемента, с выходами счетчика и дифференцирующей цепочки, а его выходы соединены непоср едственно со входами преобразователей код-аналог, соединенных своими выходами оо входами элемента ИЛИ.The goal is achieved by the fact that the device is equipped with a differential chain connected by its input to the output of the time of the master element, and sequentially connected by an OR element and a filter, while the other inputs of the decoder are connected respectively directly But with the output of the output element, with the outputs of the counter and the differentiating chain, and its outputs are connected directly to the inputs of code-analogue converters connected by their outputs to the inputs of the OR element.

На чертеже представлена функциональ на схема устройства задани возбуждени т гового генератора тепловоза.The drawing shows the functional scheme of the device for setting the excitation of a locomotive traction generator.

Устройство содержит дешм{)ратор , один из входов которого соединен с|источникой преобразуемого сигнала (на чертеже не показан), второй вход - с выходом врем задающего элемента 2, третий и четвертый входы - с выходами счетчика 3, а п тый вход - с; выходом дифференцирующей цепочки 4. Входы счетчика 3 и дифференцирующей цепочки 4 подклю чены к выходу элемента 2.The device contains a remote {) rator, one of the inputs of which is connected to the source | of the signal being converted (not shown), the second input - with the output time of the master element 2, the third and fourth inputs - with the outputs of counter 3, and the fifth input - with ; output of the differentiating chain 4. The inputs of counter 3 and differentiating chain 4 are connected to the output of element 2.

Claims

The outputs of the decoder are connected to cc. the inputs of the converters 5, 6 are the code analog connected via the element OR 7 with the filter 8. The output signal from the filter 8 enters the control circuit of the heat of the cart. The device works as follows. The switching-on time of the master element 2 is transferred over the counter 3. At the same time, its output signal will open the decoder 1 for passing pulses from the source of the converted signal to. to the empty converter 5 codecode and to pass the setpoint signal to the installation input of the filled converter 6 code-analogue. Converter 5 code-analog will be filled until the time specified by the Element is turned off.

2. Turning off, BpeMsf, the master element 2, by cutting off its impulse, closes the decoder 1 to transmit pulses from the source of the converted signal and turn on differentiating chain 4, the output signal of which will return the converter Q code-analogue to the initial state. The output signal of the converter code-5 through the element OR 7 and the filter 8 will go to the control circuit of the locomotive. The next time the master element 2 is turned on, a similar cycle will occur, with the difference that the counter 3 will open the working input of the converter 6 code analog and the installation input of the converter 5 code analog. The invention The device for specifying the excitation of a locomotive traction generator, which contains the time setting element and the source of the converted signal, the decoder connected by one of its inputs to the output of the source of the signal being converted, the counter connected by its input to the output of the setting element, and code-analog converters connected from a decoder characterized by a heme that, in order to increase reliability, it is equipped with a differentiating chain connected by its input to the output of the time of the master element, and in series with Together with the OR element and the filter, the other inputs of the decoder are connected directly to the output of the master element, respectively, to the outputs of the counter and the differentiating chain, and its outputs are connected directly to the inputs of the code-analogue transducers connected to the inputs of the OR element.
