Description
При засветке через отверстие 3 диода 4 датчик I выдает импульс, который через вентиль 6 поступает на вход двухразр диого счетчика 7. За врем первого оборота подвижна система датчика успевает стабилизироватьс , замер длительности временного интервала производитс за врем третьего оборота диска 2.During illumination through the opening 3 of diode 4, sensor I emits a pulse, which through valve 6 enters the input of a two-discharge counter 7. During the first turn, the movable sensor system has time to stabilize, and the duration of the time interval is measured during the third turn of the disc 2.
Второй импульс датчика 1 через открытый вентиль 6 вызывает по вление уровн напр жени на выходе второго разр да счетчика 7, который, воздейству на «единичный ввод триггера 8, переключает его, формиру начало временного интервала.The second pulse of sensor 1 through an open valve 6 causes the appearance of a voltage level at the output of the second discharge of counter 7, which, acting on a single input of the trigger 8, switches it, forming the beginning of the time interval.
Третий импульс датчика 1 приводит к по влению«единичных уровней на выходах первого и второго разр дов счетчика 7. Одновременно с выхода «И схемы 9 «единичный уровень переключает по нулевому входу триггер 8в «нулевое состо ние, формиру конец временного интервала. Уровень с выхода схемы «И 9 одновременно воздействует на «единичный вход триггера 10 и переключает его, тем самым закрыва вентиль 6, запрещающий дальнейшее прохождение сигналов с датчика 1. Сигнал с выхода триггера 8 подаетс на измеритель I временных интервалов, информаци которого пропорциональна удара.The third impulse of sensor 1 leads to the appearance of "unit levels at the outputs of the first and second bits of counter 7. At the same time, from the output" And the circuit 9 ", the unit level switches the trigger 8 to the zero input to form the end of the time interval. The level from the output of the "AND 9" simultaneously acts on the "single input of the trigger 10 and switches it, thereby closing the valve 6, prohibiting further signals from the sensor 1. The signal from the output of the trigger 8 is fed to the meter I time intervals, the information of which is proportional to the impact.
