Description
Перед работой реле 9 настраивают на врем Гс. доп.. Делитель 4 настраивают таким образом, чтобы значение сигнала на его выходе было равно 0,37 от значени сигнала на его входе.Before the operation of the relay 9 is set to time Gs. add. Divider 4 is adjusted so that the value of the signal at its output is equal to 0.37 of the value of the signal at its input.
В начальный момент выхажнвани срабатывает элемент 3 и на входе делител 4 запоминаетс сигнал, соответствующий фактическому начальному значению контролируемого параметра.At the initial moment of vyhazhvani, element 3 is triggered and at the input of the divider 4 the signal corresponding to the actual initial value of the monitored parameter is memorized.
Одновременно с элементом 3 пам ти срабатывает реле 9 времени.Simultaneously with the memory element 3, the time relay 9 is activated.
В процессе выхаживани значение контролируемого параметра уменьшаетс и при равенстве сигналов на входах элемента 5 сравнени срабатывает пороговый элемент 6. Если фактическое значение посто нной времени Гс меньше времени Гс. доп.. то сигнал с порогового элемента 6 поступит в элемент 8 управлени раньше, чем сигнал от реле 9 времени, и команды на правку шлифовального круга не будет.In the process of nursing, the value of the monitored parameter decreases even if the signals at the inputs of the comparison element 5 are equal, the threshold element 6 is triggered. If the actual value of the constant time Gc is less than the time Gs. In addition, the signal from threshold element 6 will go to control element 8 earlier than the signal from time relay 9, and there will be no commands for editing the grinding wheel.
При времени Тс больше Гс. доп. сигнал от реле 9 поступит в элемент 8 раньше, чем с порогового элемента 6, и тогда блок 7 выдаст команду на правку шлифовального круга.At time Tc more Gs. additional the signal from relay 9 will arrive in element 8 earlier than from threshold element 6, and then block 7 will issue a command to edit the grinding wheel.
Реле 9 может быть настроено и на врем , отличное от значени посто нной времени системы. При этом коэффициент делител должен быть изменен в соответствии с уравнени ми, описываюш,ими переходные функции системы.Relay 9 can also be set to a time different from the constant time value of the system. In this case, the divisor coefficient must be changed in accordance with the equations described by them, the transition functions of the system.
